Review: Unseen Reality; Kastner

Kastner’s is one of two “most important” books in physics and cosmology that I’ve read (and in my opinion of course) over the past 7+ years, the other being “Singular Universe” by R. Unger and L. Smolin. How many books have I read addressing the subject of “quantum mysteries”? Paradoxes of the “double slit experiment”, “action at a distance”, “the impact of the observer”, and so on. Except for hidden variables, mostly rejected for good reasons these days, all of the *explanations* are either mere speculative descriptions of phenomena taking place independently of their observation, or they explain them away. Dr. Kastner (building on the work of her mentor John Cramer) does actually explain these phenomena without hidden variables! Whether you like her hypothesis or not, it has to be a contender.

“Unseen Reality” is Kastner’s very good explanation for a popular audience familiar with the basic issues of quantum mysteries. She also has a more technical version for physicists: “Transactional Interpretation of Quantum Mechanics”, very expensive, and filled with the math to back her up. I include a link to it here for completeness. If you can follow this more technical version, you probably aren’t interested in my opinion anyway!

I have taken the liberty of modifying this review by adding (following Kastner) a short review of “Quantum Ontology” by Peter Lewis. Lewis’ book is a summary of the ontological implications of various interpretations of Quantum Mechanics. Most was review for me but I read the book because he mentions Kastner’s “Transaction Interpretation”. I criticized Lewis (in the review) for failing to note what Kastner claims is the ontological implication of her interpretation, but I now realize the possibility that Lewis was working from her longer more technical book which I have not read. It is possible she does not introduce the ontological implications of her work until “Unseen Reality” published only the year before Lewis.

In 2019 Dr. Kastner published a second book: Adventures in Quantumland in which she reprises and expands on this earlier book. I review and comment on the later book here.

Understanding Our Unseen Reality: Solving Quantum Riddles (Kindle Edition 2015)

Ruth E. Kastner resolves 100 year-old quantum mysteries. Moreover, she explains them without explaining them away and all-the-while retains the fundamentality of the particles (as compared to the Schrodinger wave) and forces in spacetime. She calls her theory a “transactional interpretation”. We’ll see why in a moment. The solution proposed supposes (an inference anlogous to the status of atoms in 1850) that physical reality, the universe explored by science (particularly physics), includes something besides spacetime. She calls this Quantumland and compares it to the bulk of an iceberg which exists beneath our sight while the tip, spacetime, is only a small part of all of what is the physical universe.

All quantum phenomena (“incipient transactions”) happens in this bulk part of the iceberg. It has important qualities. Foremost, it is outside spacetime. Second, unlike the bulk of a real iceberg, incipient transactions are in principle invisible to observation as that is commonly understood by science. What science can observe is what makes it from an incipient transaction to a real transaction, and in that transition moves from Quantumland to spacetime. At that point, an event becomes measurable, essentially observable. This has nothing to do with whether or not it is observed by human beings. It isn’t human observation that turns an incipient transaction into a real transaction but the response of absorbers to an emitter. An absorber might be a molecule in a human eye that evokes some response in human consciousness, but it might also be an atom on the surface of a rock. Our instruments are absorbers, the environment, the whole of spacetime, is filled with absorbers whose transaction-capable atoms can respond to an offer wave outside spacetime.

Here’s how the system works as I imperfectly understand it. Inside Quantumland there is constantly going on an exchange of virtual particles. These are “offer waves” of an emitter (say a photon or an electron), and these waves are met by corresponding “response wave” that comes from the side of every particle surrounding the emitter that can potentially absorb the particle implicit in the offer wave. Individual absorbers can only respond to a fraction of the offer wave, that fraction that the response encounters. When offer wave and response wave meet (remember this is all taking place outside spacetime) we have an “incipient transaction”. The meeting sets up probabilities for any part of itself to become a real transaction. No part of the offer-response (incipient) process transfers energy. Only one of a possibly near infinite number of incipient transactions can become a real transaction and in doing so transfers a quantum of energy. The process is fundamentally random. When it happens, that event enters spacetime and we can measure it!

Quantumland where virtual particles are the origin of the forces (strong, weak, and electromagnetic at least) we experience in spacetime is not particularly controversial in quantum mechanics and is the main reason that physicists believe there is a quantum realm even though we cannot observe it directly. Dr. Kastner explores this origin of forces in her book as well, but her addition to the whole idea is that all of this quantum stuff takes place outside spacetime but remains a part of “the physical universe”. It is a transaction’s emergence into spacetime that makes it observable! Quantum physics merges into classical physics because as quantum events emerge into spacetime, one of many incipient transactions into a real transaction, energy is transferred. As these events cluster, quantum physics becomes classical physics. Kastner makes clear how each aspect of the relation between Quantumland and classical physics in spacetime result in what quantum experiments tell us. She explains action-at-a-distance, incipient transactions take place outside spacetime and are not constrained by the speed of light. But the effect cannot be used to send information faster-than-light because sending information requires actual transactions that have entered spacetime and therefore restricted to the lightspeed limit!

There is even more to Kastner’s book than I explore here. She spends time on the distinction between mind-as-absorber and absorbers generally, that is the physical universe, and explores a role for Quantumland in an explanation of free will. Significantly, her explanation really is an explanation. She writes beautifully for a non-mathematical audience and her analogies (many more than the iceberg) capture her concepts well. At least I thought I was with her at every step. I’m sure some of the concepts are oversimplified for the lay audience (including myself) but I think there is a genuine insight here. Excellent book if you have any interest in quantum mysteries.

Quantum Ontology: A Guide to the Metaphysics of Quantum Mechanics (Kindle Edition 2016)

A book at the intersection of quantum mechanics and metaphysics. Lewis focuses on the three dominant interpretations of quantum mechanics and various of their variations exploring the advantages and disadvantages of each from a viewpoint of the metaphysical ontology (the philosophy of what exists or what is real) of the universe and our experience. On the whole the book delivers on what it promises. While it fails to come to any definite conclusions, the author is clearly biased towards “the many worlds” view, one of the three dominant interpretations of quantum mechanics.

When I first bought the book I searched it for a mention of my own favorite interpretation, the “transactional theory” of Cramer and Ruth Kastner (see my review of her book “Understanding our Unseen Reality: Solving Quantum Riddles”). Lewis casts this interpretation as one of a class involving temporally reversed cause. Oddly he fails to mention that Kastner herself rejects this interpretation based precisely on a unique ontological commitment; that quantum phenomena take place outside (as Kastner puts it “underneath”) timespace. In her view, the quantum phenomena only appear to be causally reversed from a viewpoint within time but in reality no such reversal occurs because prior to the phenomena being particularized as energy is transferred in timespace they occur outside of it. This is a big ontological consequence that Lewis utterly fails to notice.

But aside from this quibble, the book is a good review of the dominant interpretations of quantum mechanical phenomena and their associated ontological implications.

 

Review: Singular Universe and Reality of Time

selfie

Of all the physics and cosmology I’ve read over the past 7+ years this book stands out as one of the two most interesting, the other being Ruth Kastner’s “Understanding Our Unseen Reality: Solving Quantum Riddles”. Now this is a tough call because I’ve read a lot of great books, But this book inspired not only this review but one of my books, while Kastner’s work manages to actually account for phenomena like “action at a distance” and the paradoxes of the “double slit experiment” without hidden variables or merely explaining them away.

The crucial insight of Singular Universe is that time is not only real but the most fundamental (brute) characteristic of our universe. No other property of our universe (including space) could begin to exist in the absence of time. Impressively, Unger manages to disentangle the “global time” that both authors insist must be real from the temporal insights of Special and General Relativity. Einstein discovered that the measurement of time can only be a local measurement (from within some relative reference frame) but that discovery does not at all preclude a global time for the universe as a whole. In terms of shaking up modern physics, this might be Unger’s greatest contribution. Smolin adds to Unger’s fundamental a rationale accounting for the crystallization of “the cosmological settings”. He has a hypothesis grounded in empirically verified cosmology (black holes) suggesting an answer to the question “why did the cosmological settings come out with the values they have?” I think his rationale is far fetched but in the present community of cosmologists it counts as a strong rational hypothesis.

The Singular Universe and the Reality of Time: A Proposal in Natural Philosophy (Kindle Edition 2014)

This is a superb and important book. It is quite long and two books in one, the first by Roberto Unger and the second by Lee Smolin. Both address the same topic, the reality (and fundamentality) of time and the failure of the Newtonian paradigm when applied to the whole universe. Each author takes a different approach to the subject on which, for the most part, there is a wide area of agreement between them and a few differences as concerns some details.

Neither book is “popular science”, but rather both are serious attempts at a novel “natural philosophy” that contributes (or should contribute) to advancing the subject of cosmology by illuminating little considered implications and interpretations of the physical (standard model) and cosmological data we already have.

Unger’s approach is more purely philosophical. He begins straightforwardly enough with the common (in science) metaphysical assumption that only the material universe is real. Although he abjures a strong metaphysics and offers instead what he calls a “proto ontology” that does not attempt to fix the kinds of things there are in the universe for all time, he is nevertheless stuck with this basic materialism and that forces him onto one of two horns of a dilema. The mystery is the extreme unlikeliness of “the settings” that make the universe hospitable to life. Most physicists being philosophically trapped in the “block universe” model of relativistic time (which in effect denies the fundamentality of time by casting time in terms of spatial geometry) have gone over to the multiverse as an (untestable) explanation (along with the “anthropic principle) for the unlikely values of the settings in our universe. From Unger’s viewpoint, the opposite tack, assuming time to be both real and fundamental, and that there is a global “preferred time” (perfectly compatible with relativity given appropriate alterations in what Unger calls its “metaphysical gloss”) which all means that there is nothing in the physical universe that is immune from the effects of time including the laws and settings which change (albeit in this universe phase very slowly) and that instead of multiple universes, the unlikeliness of our settings is explained by our one universe having an indefinite (not eternal) past that has gone through phases having various settings and has just happened, in this phase, to end up with the settings it has. Unger believes that this option, the “indefinite past” and a single universe at a time is better than the multiverse hypothesis because it provides for a causal (although the laws governing causal interactions will be different from phase to phase) continuance between phases. Time and causation entail one another, they are both fundamental in that what ever the laws and settings operative at a given moment happen to be, there is still some sort of causal interaction in time. As difficult as it might be to detect records of past universe phases (that is prior to our own big bang) such detection remains possible and therefore within the scope of science, while non-communicating multiverses that preclude any interaction do not.

Unger covers his ground very well. His approach is to revisit the same questions and issues over and over again like a skeleton on which he lays a little more flesh with each pass. In the end he leaves out two things. He offers no specific explanation for our particular settings this time around, and he fails to address how it is that the laws and settings we measure in our universe phase happen to hold over a range of conditions from the cold of interstellar space to the interior of stars. He admits that in our present “cooled down” universe the laws and settings appear very stable. His failure to offer any explanation for their stability does not detract from the argument that time is real and there is only one universe at a time. He explicitly leaves the rest to Lee Smolin.

Smolin is a physicist writing here as a natural philosopher and he is very good at it. His argument here is a reprise of his book “Time Reborn”. He’s had a few years to chew over these ideas, and I think his more concise treatment here is clearer than it was in that book. Smolin does offer two possibilities for explaining what Unger leaves out. The first is his “principle of precedence” which goes only part of the way, explaining how it is that the settings might get set, but not why they are what they are. The second, his notion of “cosmological natural selection” does actually explain both the settings and to some extent their stability across the wide range of conditions in our present universe. But these explanations rely on two rather speculative ideas.

First, new universes arise from the interior of black holes. The point of the settings and their stability is that these two properties are necessary to produce lots of black holes from massive stars. Such black holes in effect set the parameters of the universes they generate. Our own universe is in fact such a baby universe generated by a black hole in another universe. Second, the range of possible (or likely) settings of the baby universe would be different than those of the parent universe but only and always in a small range. This is what sets up the “natural selection”.. Universes whose properties happen to produce a lot of those kinds of black holes will end up dominating a history of branching universes such that the great majority of them have settings similar to ours just so that they can produce a lot of black holes.

Of course the very idea that universes are born in black holes (or that ours emerged from a black hole) is at present utterly beyond observational science, so this is sheer speculation whose only relation to physics (as distinct say from asserting that “God did it”) is that there is a potential causal chain (no matter what transformation the settings might undergo in between) connecting parent (black hole) to child (new universe). Smolin fails to say why it is that the variation in settings through black holes from massive stars (he explicitly rejects primordial black holes as selectable parents for this reason) should vary by only a little.This property is what makes them selectable. If the settings vary by very much, the outcomes (as far as black hole creation are concerned, not to mention life) will be random and not converge to an optimal type. There is no mention here that the coincidence of these same settings being conducive to life AND black holes is itself something of a mystery. Dr. Smolin spends a small chapter addressing the nature of qualia in consciousness, but he is interested in suggesting an example of precedent-agnostic causation (brain correlates of qualia) and not the coincidence of settings conducive to both black holes and life.

Both men address “the unreasonable effectiveness of mathematics”, and claim, reasonably enough given their history-first foundation, that present mathematics happens to be fit-able to present physics but that the discipline has no magic insight into the nature of every particular event in the history of the universe (Smolin) or into some Platonic structure that is metaphysically prior to actual history taken in aggregate (Unger). This is one of the more fascinating parts of both arguments because both men get to the same place about math in very different ways.

It is unfair to criticize either author for not solving every problem. For both this book is to be the foundation of a natural philosophy, not its completed edifice. Both author’s arguments rest on a foundation of time, causation, and therefore history as being fundamental. The universe is what it is and if we discover structure in its behavior, that structure, mathematically describable regularities, it doesn’t mean those very regularities weren’t different in the past and won’t change in the future. There is every reason to believe they are both onto something here. Smolin’s illustration of how we slip from an observation of causal stability in the present universe to a mistaken notion of absolutely deterministic precedents is illuminating to say the least. All of this above does not do justice to the over-all philosophical integrity of this work. Drs. Unger and Smolin happen to discover in one another kindred spirits as far as this business of the reality and fundamentality of time is concerned. I hope there will be more collaborations between them in the future.

Review: After Finitude

My intuition tells me this will be an important book in the development of my own philosophical thought. It will prove important to my philosophy and theology although like all materialists, Meillassoux rejects theology as nothing more than “speculative metaphysics”. Yet he is brave enough to call what he writes here “speculative realism”, and it is speculative because his starting point is very much antirealist in orientation. Fundamentally an antirealist (he might disagree with me), he cannot know that he is correct. Like my theology (I cannot know that God exists), the evidence that Meillassoux is correct, is the result; his grounding of the insight that scientific discovery is about the world.

In my essay “Realism and Antirealism” here on the blog I note that “…one of the possibilities for explanations of experience in antirealism is realism.” This comment, made in a marginal note to Zizek’s “Less than Nothing” was made in the context of Zizek’s discussion of Meillassoux, and Meillassoux himself does not disappoint. The point of this little book is to recover realism, that is the genuineness of scientific insight into the nature of a world independent of experience, that there is a world independent of experience and that we can reliably have knowledge of it. Meillassoux achieves this with a very clever argument concerning the relation between necessity (there isn’t any except…), contingency (the only necessary thing about the world is that everything is contingent), and consistency — the reliability of the world’s regularities present to experience really is in the world itself and not merely in the “categories of our experience” a la Kant.

Meillassoux here is after nothing less than establishing a warrant for “scientific realism” on an antirealist foundation. As I note in my review below he doesn’t quite finish the job. He does manage to lay out all the elements of the argument and provide reasons for the validity of the assumption that science discovers truth about the world “as it is” in the absence of our experience of it even as he denies the validity of the Principle of Sufficient Reason, a principle “scientific realism” implicitly embraces. This is a singular achievement on his part. I’m glad I decided to read him.

Besides Meillassoux, there are two other philosophers who comprise the “New Realist” school Maurizio Ferraris and Graham Harman. I have reviews of both of them now with commentary comparing the three.

Quentin Meillassoux, “After Finitude” (Kindle edition 2013) Reviewed for Amazon

Meillassoux’s writing reminds me much of other top tier philosophers of the present day like E. J. Lowe (recently passed away), David Chalmers and a few others. Not in what he says of course his starting points and subject are different, but stylistically, carefully crafting his arguments and at each point stopping to describe and evaluate alternatives advanced by his contemporaries and historical predecessors. In “After Finitude” he begins, conceptually, with Hume and Kant, accepting with the latter that the proper starting point for philosophy is the world experienced by humans; what can be thought, but rejecting in both the idea that we cannot come to “know”, in the sense of rely-on experience, to deliver genuine insight into the world in itself.

Meillassoux rejects speculative metaphysics (mostly coming down these days to religion) and accepts the generally anti-realist notion that the Principle of Sufficient Reason, need not apply to the world apart from human experience of it, but holds that the principle of non-contradiction should not be abandoned. Even if we cannot conceptually embrace infinite possibility (totalize the world), it cannot be that the world contradicts itself. All of this comes down to there being no absolutes, no “necessary being” and no “thinkable totality of all possibility” except for the fact of contingency. The only absolute for Meillossoux is that everything is contingent and might have been other than it is.

But all of this leaves historical and present day (postmodern) anti-realists in the position of claiming that we cannot know anything beyond our experience at all, and it is this mistake that he aims to rectify. Despite his general acceptance of the Kantian starting point, he insists that the achievements of science over the last two centuries well demonstrate that we can discover (through an objectivity emerging from shared experience, the results of repeated observations and experiments) much that is true about the world of the past and the present even if such truth lacks the a priori assurance of mathematics.

That problem comes down to why, if it is correct to reject the Principle of Sufficient Reason for the world apart from human experience, the world, that is the laws of physics, seem to be so stable? If the history of the universe comes out to its not-necessary “facticity”, that it is the way it is merely by chance, why aren’t the laws and regularities constantly changing rendering our ability to comprehend anything, even to be conscious at all, impossible? Kant’s answer to Hume was that the stability is only the effect of the categories of our consciousness, and if the in-itself (Kant’s noumenon) were not stable there couldn’t be any consciousness in the first place. But Kant accepted the Principle of Sufficient Reason which Meillassoux rejects. Instead he points out than an unstable in-itself might appear stable for long periods (essentially an anthropic argument). Instability need not mean moment-by-moment instability.

Meillassoux argument rests itself on our ability to “mathematize” our shared experience. That we can describe phenomena in-the-world in mathematical terms and discover not only that 2+2=4 (a priori) but also that E=mc^2 (a posteriori) speaks to us of the world’s stability. But he never quite gets around to telling us how mathematics grounds the stability. Indeed I do not see how it can because if it did, that would render the world necessary.

But there is a further problem here. If instability were really a quality of the in-itself and the universe was infinitely (or trillions of years) old, a few tens of billions of years of stability would not be problematic. But if he is right about the meaningfulness of scientific discoveries, then the universe is only 13.8 billion years old and yet the laws have been stable at least since the moment of nucleosynthisis a second or so after the big bang. That means the laws have been the same for 13.8 billion years minus 1 second! Extraordinary stability indeed!

To sum up, a beautifully written book, well argued, a delight to read, with many insights into the relation between human experience (the for-us) and the antecedent (the for-itself) world. But it doesn’t quite finish the job, something Meillassoux says he must let go of (for now I presume) at the end of the book. A fantastic example of how good philosophy is done even if, in my humble opinion of course, he begins from the wrong starting point and never quite finishes.

Review: Explaining Postmodernism

 

Explaining Postmodernism: Skepticism and Socialism from Rousseau to Foucault

Postmodernism a popular subject these days. What is it? What is its history? There are a number of books on the subject — just key ‘postmodernism’ into an amazon search. I have read only one of them, this one, published in 2010. Hicks has written a great introduction here to both philosophical history and present implications. Here is a LINK to the book on Amazon. The subject ties into my recent essay REALISM and ANTIREALISM. Postmodernism is a final descent, very much the logical (or illogical) end point to Antirealist madness!

Not often I get to say of a non-fiction book that I didn’t want to put it down and was sad when I reached the end. Except for a sense of the movement’s nihilism, I didn’t know much about Postmodernism, but Dr. Hicks has covered the ground. He begins with a broad brush of what postmodernism stands for metaphysically (anti-realism), epistemologically (skepticism), ethically (collectivism in the social, educational and political sphere) and aesthetically (the meaninglessness of art and criticism). One gets the impression that he knows the subject well. His attention to detail is that of the scholar and even the true believer, but he hints slyly at the movement’s absurdity even here. From his review he goes backwards and traces the roots of the movement beginning with Kant’s response to the Enlightenment in an attempt to shore up the authority of the Church, and up through Rousseau, Hegel, Schopenhauer, Fichte, Nietzsche, Marx, and then Heidegger to the later 20th century with Foucault, Derrida, and Rorty. There are many other voices mentioned along the way (Kierkegaard plays a role as does Freud). Besides philosophers he traces political movements of the left and the right in opposition to the Enlightenment’s development of capitalism resting on individualism.

In the last chapter HIcks returns to Postmodernism proper and its absurdity from the metaphysical and epistemological to the political and aesthetic. In 200 hundred years every political and social consequence of anti-Enlightenment philosophy, every prediction and political hope has singularly failed. Postmodernism is the response to this failure by philosophers who come to the conclusion that if the foundation and development of the anti-Enlightenment movement over 200 years is rotten the only thing left to do, besides admit that you are wrong, is attack and destroy what the Enlightenment produced. Even Nietzsche (who Hicks returns to illustratively at the end) presciently suggests that one can take anti-realism and nihilism too far leaving the postmodernists to “quote Nietzsche less and Rousseau more”. Not only is Postmodernism nihilistic, it is destructively so, the bitter fruits of jealousy over the failure of collectivist anti-realism and seeming political, economic, and social success of Enlightenment realism, rationalism, and individualism.

An excellent review, thorough, scholarly, and easy to read. I find Hick’s style both serious and humorous at the same time. Superb!

Review: The Big Picture

selfie

This is my Amazon review of Sean Carroll’s “The Big Picture: On the Origins of Life, Meaning, and the Universe Itself”. Although I am a theologian, I read a lot of books by atheist/materialist scientists. In my reviews of these books, I leave religion out if they do. But Dr. Carroll’s book is as much about his scientific theme as it is a book explicitly critical of religion all the way through. In the following review I mention this only briefly, but I have written also a longer piece here in the blog covering this ground more thoroughly. The link will take you to it. Meanwhile here is a link to Carroll’s book on Amazon. Hope you enjoy the review. —

Sean Carroll’s book has two broad themes. The first is to explain to us how it is that everything we observe in the universe, including all of what makes up human experience, emerges from the physics that lies at the heart of the universe, what Carroll calls “the core theory”; quantum field theory and the “standard model” of particle physics. Here he makes the case that what exists is what emerges from very special (low entropy) conditions in the universe’s past. It all comes down to the the second law of thermodynamics, the fundamental forces and the fact that the universe is far from an equilibrium state. In this he does an excellent non-technical job of describing how it is that the universe we find produces so much complexity from but humble beginnings. As he moves up the chain of complexity (emergence and phase changes) he applies the same principles of development to everything from galaxies and stars to life, consciousness, and the complex mentality of human beings. He admits that we have a much better explanation of the emergence of stars and even life from physics and chemistry than we do for the emergence of consciousness from biology. But he is confident his model works all the way to the top.

In his second theme, Carroll is concerned not only with establishing that physics tells the right story, but that it is the only story and no other story is reasonable. Put another way, by his lights, any other story is highly unlikely. By this he doesn’t mean that we don’t use different languages to speak of particles, biology, or feelings, but that nothing besides emergence from purely physical roots is going on as concerns consciousness, moral sensibility, and the seeming appearance of free will. Since the argument that there is more than physics going on here comes mostly from religion, he pointedly and repeatedly criticizes it claiming it has no genuine bearing on anything real. To be sure he doesn’t claim to know that there is no God, only to have established (he believes) that God’s reality is very very unlikely. One wonders why he feels the need to be so forceful about this, but the reason is clear enough in the book’s last section where he attempts to make sense of experiences that (to many) most strongly suggest that there is something besides physics going on; meanings in life, love, moral choices, desires, a sense of self, and what seems to us to be robust free will. To explain these, he applies the same model of emergence and phase change to consciousness and from there to all things mental. He confidently asserts that all of these things are nothing more than “a way of talking” about phenomena that are, in the end, nothing but physics.

What perturbs me about this second theme is certainly not his desire to mention (at least) and critique the competition but that he critiques such a straw man version of it. Time and time again he demonstrates his grasp of the nuances of physics while criticizing grossly superficial and unnuanced notions of what religion is and what it says.

There are other recent mainstream books that cover much of this same ground as concerns cosmic evolution, life, and even consciousness. Dr. Carroll is good here. He writes well, non-technically, and does an good job of stretching the idea of emergence into the human experience. That this is a part of the whole story is undoubtedly true, but it is unwise to declare that it is the whole story, or even likely the whole story, without knowing the whole story (which he admits is not known), or at least appreciating what the competition actually says.

Review: Zizek End Times

I recently posted a review of Zizek’s “Less Than Nothing: Hegel and the Shadow of Dialectical Materialism” (2013) here in the blog. A book inspiring my “Realism and Antirealism”. Here is my Amazon (October 2016) review of his earlier “Living in the End Times” (2011). When I wrote this one I hadn’t yet keyed in to Zizek’s fundamentally antirealist outlook, something that became obvious in the opening pages of the later book. I was sensitized to the distinction by Maurizio Ferraris, a continental “new realist”, and an excellent book on Postmodernism by Stephen Hicks (The links will take you to their books on Amazon) both read in between the two Zizek books. The review does however capture my intuitive realist rebellion to Zizek’s approach. Now I understand why.

I’ve watched Slavoj Zizek through several YouTube interviews, a very articulate and animated speaker who always seems to have an unusual but common sensical slant on goings on in the world. I bought this book because I thought I might find more of the same between its covers and the title was especially interesting. But how to review this book? The author has a vast background in European social and political philosophy from Marx and Hegel (on whom he particularly rests for the grand picture) to more contemporary figures like psychiatrist/philosopher Jacques Lacan and Alain Badiou (a modern French Marxist) one or the other of whom is mentioned on almost every page!

This book ranges over the entirety of Earth’s present social, political, and economic space. Marx and Hegel updated to the present serve as the backdrop. Of course Freud is in there too along with a few dozen other philosophers and authors both popular and literary. Zizek brings into this business not only thinkers and writing, but film, architecture, modern art, and technological transformations. War and peace, terror, contentment, and sexual mores all fall within his gaze.

Within this scope, with every political, cultural, economic event event, philosophy, and interpretation, nothing is quite as it seems. Freedom is not free, goodness is not entirely good, nor badness all bad. Every “ism” is evil and yet highlights something important about the human condition. You name it, and Zizek will find a viewpoint that stands whatever the “it” is, on its head. Much of this would be laughable, but Zizek’s viewpoints (and he takes many of them, often opposed to one another for the sake of illuminating consequences actually felt by real human beings) are not easily dismissed as fantasy. Each has something to say to us. A few struck me as unfair, perhaps contrived, but that would be reading my own personal political and social biases into what I know of history and psychology. None of his varied perspectives lack force. Perhaps there is an over emphasis here or an under-emphasis there, but who is to say if it is I or he who has the greater insight into the true weight of it? It is clear that he is very well read and deeply thinks about all that he encounters.

Does he ever answer the question? Are we living in the end times? I think, if you mean the end of biological humanity as such the answer would be no (unless someone triggers a global thermonuclear war). But if you mean the end of life as it is presently known and understood, the answer is probably yes. What will it be that gets us? Economic exhaustion? Ecological (and so biological) collapse? Old fashioned war, or a new fashioned loss of the very center of our “selves” to virtual reality; “the Matrix” for real, not imposed by aliens but by our own economic elite and not even the elite as individuals but the system itself! Quite possibly it will be all or much of it together. Nor is he sanguine about what will follow. His view of history is pessimistic. Civilizations and political systems come and they go and when they go what replaces them, while perhaps different from what went before, is no less oppressive to the majority of individuals alive at the time. His is not a view of ever evolving perfection, of goodness eventually triumphing over evil, but rather more of the same, more of the mix of good and bad that makes human beings what they are now and ever will be.

In the end he reverts back to his updated Marx. The governments of Eastern Europe were evil, but what replaced them was also evil and continues to wreck its corrosive influence. Interestingly he discerns, in the political and economic patterns of the world, the further expansion and domination of capitalist-oriented systems regardless of the politics of individual nations. He in fact discerns the emergence of the “market state” from the nation state, but he never gets around to naming it. It is no doubt a mix of adaptation to the totality of the global situation, though he does loudly proclaim that for all that adaptation it is itself a part (if not the main part) of our present problem and about this he is surely correct. Oddly, for a Marxist-Hegelian, he doesn’t seem to recognize its present inevitability.

This is a book of great scope. If you are interested in a dense survey of our age from the viewpoint of an updated Marxist/Hegelian “rolling on” of history written by a scholar of the highest caliber (which doesn’t automatically make him right) then this is a good book for you. If you prefer a simple or unambiguous answer, then perhaps it is not.

Book Review: Less Than Nothing, Zizek 2013

The text of my Amazon review of Slavoj Zizek’s “Less Than Nothing: Hegel and the Shadow of Dialectical Materialism” Verso Books 2013. I know I could post a link, but Amazon has enough power already! If you are interested in the book, here is a link to it and other reviews of it.  Here is a recent blog post of mine on Antirealism and Realism inspired by  Zizek and other reading like this article on Antirealism from SEP.

 

This is a sweeping review of Hegel’s “dialectical method”, its application in his history and phenomenology, and then its outworking in the thought of Hegel’s contemporaries and successors. All of this is Zizek applying Hegel (beginning with the genesis of Hegelian-ism in Kant) to [mostly] continental philosophers influenced by Hegel, which comes out to just about everybody in the European antirealist tradition that Kant began. Besides Hegel Lacan takes up the most consideration but beyond him there are many many others to numerous to name.

Philosophers never declare themselves for “realism” or “antirealism”, a division always reflected in their thought. Zizek is an acknowledged heavyweight in the antirealist domain and his dominant interests, psychology, and political history, reveal themselves in all the threads of this book. He covers these and many more subjects (and philosophers) as he interprets them through Hegel. Sometimes he notes where he thinks their thought “goes wrong” (relative to Hegel) but more often he uses their material to illustrate the added insights they bring to the subject matter via their Hegelian influence.

It is impossible to cover this book in detail, but I can describe its broad structure. Imagine a wheel with a hub and spokes, perhaps a bicycle wheel. Zizek begins at the hub with a theme “truth has the structure of fiction”, almost his opening line. His writing spirals around the hub in tight circles outward toward the rim. On the way, he crosses the same spokes which in this analogy stand for both discrete subjects within the universe of his interests (and they are broad) and the philosophers whose thought he uses to illustrate his point. Round and round he goes touching the same spokes again and again each time adding more or new context with which to understand the particular subject and philosopher involved. Throughout the book, Zizek weaves together his own commentary with extensive quotes from dozens of philosophers from Kant to Meillassoux. As he crosses each spoke over again their thought is re-illustrated, re-applied to the subject matter at hand whether it be language, sex, politics, economics, history, or quantum mechanics.

I am a realist philosopher and it has been a long time since I’ve read Kant, Hegel, Heidegger, Freud, Nietzsche, or Marx. I’ve not read Lacan, or any of the many other continental antirealists of the later 20th century Zizek uses here. Zizek’s vocabulary, evolved over two centuries of antirealism, is dense, obscure, and difficult for me. But as the many subjects are touched on again and again his meaning became clearer. Thanks to the enhancing repetition, retouching each spoke, his central arguments became clearer. Was Zizek’s repetition solidifying my impressions, or was I just getting used to the lingo? Probably some of both.

There is probably more than one legitimate way to interpret Hegel, Lacan, and the rest. Zizek’s authoritative grasp of this material certainly makes his interpretation one of them, an approach to be taken seriously. He runs into trouble only when he crosses into the subject of science, represented by the association between quantum mechanics and cosmology, where he seems a bit out of his depth. His description of the relation between the Higgs field and the “true and false vacuum” (the next-to-last chapter) quotes Paul Steinhardt and is clear enough, but then Zizek goes back and casts this phenomenon in Hegelian, Lacanian, and even Freudian terms! None of this could be more than poetic metaphor, but Zizek doesn’t seem to take it that way. To me (and I opine here because I’ve read so much physics and cosmology) quantum physics as described by modern physicists, can only be understood in realist terms. If I understand antirealism properly nothing in the corpus of antirealist thought can possibly be about (signify) the quantum world which is washed out long before the point where the external horizon appears to phenomenal experience.

Although I am not an antirealist, I enjoy reading Zizek. This book is long and dense, but his enthusiasm and humor reveal themselves throughout. I enjoy reading philosophers who are passionate about their work and at the same time refuse to take themselves too seriously. It’s hard to tell if Zizek takes himself too seriously. I don’t think so, but this ambiguity coupled with a little self-deprecating humor (where do you see that otherwise in philosophy these days) is all a part of the book’s charm.

To finish this review, I do want to give kudos to the publisher (Verso Books)! I recently read a 125 page Kindle book priced at $40 (greedy publisher who shall remain unnamed). This book is 1000 pages long and only $11! Very reasonable! Highly recommended for Zizek fans and anyone interested in a forcefully argued interpretation of Hegel and much of antirealist thought from Kant to Meillassoux.

Realism and Antirealism

It has occurred to me that something theologians (of my sort) and philosopher-scientists (typically of the athiest/materialist sort) have in common is that we are philosophical realists (there is an exception concerning quantum mechanics in which realism has a technical connection to what are called “hidden variable theories”). What we both take to be true, is (1) there is a material world having a structure and history (facticity) with positive qualities preceding and having nothing to do with human consciousness, and (2) that in or with mind, we can come to know, that is accurately represent to ourselves, the structure and history of that independent world. This is not to say that we represent it perfectly or even at all when it comes to some of its more extreme phenomena. The bottom line for realists is that as concerns the bric-a-brac of day-to-day experience, what we see (experience though mediating senses) is pretty much what there is that is independent of our mental representations.

I’ve recently read two books (“Living in the End Times” [2010] and “Less than Nothing: Hegel and the Shadow of Dialectical Materialism” [2013]) by Slavoj Zizek, and two from Arthur Schopenhauer (“The Fourfold Root of the Principle of Sufficient Reason” [1813] and the first two books of “The World as Will and Representation” [1819]). It’s been 40 years since I’ve read any Hegel, Neitzsche, Heidegger, Husserl, Wittgenstein, or Marx. I have also explored modern antirealists like Quentin Meillassoux (“After Finitude” 2016), an antirealist seeking a justification for realism and the “new realist” Graham Harman who offers an ad hoc view of what is mind-independently real. The antirealist viewpoint, not the examination of the structure and nature of consciousness (their only program), but the ad hoc rejection of that structure being representative of a world radically independent of and prior to consciousness, is alien to me.

Having stumbled onto this point of view in recent reading, represented to me mostly by Zizek (who is an acknowledged heavyweight in this domain) this essay compares some consequences of the fundamental ontological stance of Realism and Antirealism. This is not an exhaustive review of either side (see the SEP entry on Antirealism here for a great introduction). My goal is to highlight what I take to be the fundamental antirealist problem and argue that it is a much bigger problem than the fundamental realist one.

REALISM

Modern realists, the “New Realists” like Maurizio Ferraris (Harman mentioned above is another of these but he never quite gets past antirealism), understand that “what we experience” are “mental representations”. What exactly constitutes “the mental” (consciousness) is hotly debated among realists, a debate I won’t get into here (see “PHYSICS AND THE EVIDENCE FOR NON-MATERIAL CONSCIOUSNESS”). But there isn’t much debate about the subjective perspective (and language) from which we are all forced to communicate both what we experience and our ideas about that seeming, including its correspondence with the external (connected up to its truth; see “TRUTH AND TRUTHMAKING”). All of these are ingredients of “the subjective” within which the external world (including the bodies containing the sensory organs on which that world impinges) is somehow or in some sense modeled. The realist’s realism consists precisely in taking this modeling to be accurate, properly representational of “what is out there” at suitable scales or graining.

This last part, the graining, is important. Modern realists believe there is “independent reality” at scales both too large and too small for human senses to probe directly; roughly anything smaller than a dust mote or larger than a mountain. Below and above these sizes, instruments enhance our senses allowing us to probe the very small and very large. We build the instruments at familiar scales, but they work to map the larger or smaller onto scales which we can sense directly. The broad assumption of realism is the map, our mental modeling emerging from instruments through our senses, is accurate. This means not only that the content of consciousness represents a real-external, but also that the structure of subjective content reflects the structure of the external.

We extend what we know (internal experience) to phenomena outside our minds by trusting the map. Modern realists even approach antirealism in recognizing that there are phenomena whose positive properties will always remain unknowable because they cannot, even in principle, be probed by macroscopic instruments. This is the quantum-real on the smallest scales and the cosmos beyond our visible horizon at the largest. But while there is no “trustable map” potentially available here, realists do not doubt there is something real and independent of mind at these extreme scales. Further they have a faith in our eventual ability to explain the emergence of the bric-a-brac world from those unknowable phenomena. Achieving this would be tacit evidence that our theoretical speculations concerning the unknowable reflects more rather than less of structure beyond the range of our instruments.

A few scientists and philosophers argue there is no independent real except for the extremely small (or even the Wave Function) which cannot be known. This “scientific antirealism” is not the same [metaphysical] antirealism I address here. Even these antirealist scientists admit that anything we elect to “call real” (for practical purposes) in the intermediate scales, is “faithfully modeled” in the mental experience of the scientist. To most realist scientists, the mental ability to conceptualize different scales itself also represents the structure of reality independent of the mind doing the conceptualizing. Unaided by instruments, phenomena on scales to which we are sensitive are real. What eyes see, ears hear, noses smell, and our bodies physically feel in their encounter with the world is all real and ordered (structured) as we perceive them even as we have also learned that at different scales reality’s structure lies beyond what senses can detect and even (possibly) what mind can conceptualize.

So what exactly is the problem with realism? Pre-philosophically realism seems, well, obvious. Early modern scientists were religious men. They grasped that God, if real, had to be consistent; changeless. They reasoned the regularities observed in the universe were a reflection of God’s constancy. That assumption grounded the idea that the “laws of nature”, the physical laws of God, were discoverable and mathematically qualifiable.

Later, early empiricist philosophers (Locke, Hume) dared to suggest that the regularities of nature were the constituents of “material stuff”. The closure of physics on itself is taken to be a sign that the properties of the physical come from nothing other than the physical; self-generating brute fact. God’s constancy, even his presence, becomes redundant. Being could be self-sustaining! Antirealism began as an attempt to save God, more precisely the doctrines of the Church about man. There is some irony in that today’s antirealism is even more radically atheistic than most realism. Materialist-realists mostly admit that God, as a source, an origin, is not incompatible with physics, merely redundant. Antirealists, by contrast have come to assert that God is impossible.

Realism today, among scientists, has little connection with theology. But on becoming atheist, realism faced a philosophical problem. What guarantees the veracity of the map, the connection between our singular individual internal experience and the external world? We know the brain is a warm, wet, electrochemical environment, obviously a material object constrained to regular behavior consistent with natural law. Most scientists suppose not only that this brain, by itself, is sufficient to produce consciousness, but that this subjectivity properly models the world as our senses relate it to us. How exactly does that work? Without God, in this case a bridge between the internal and the external, what justifies the internal conviction that experience reflects reality?

We know that brains fail and that in failing they can produce all sorts of deceptive maps. The problem, called the “representation problem” is explaining how it is they produce truthful models most of the time? Truth, means there is some one-to-one correspondence between something in the world and its representation in subjective experience such that we (at least humans) can claim knowledge of the external world as represented in internal experience. If one has God of course the explanation is available. God (via some mechanism he uses to add mind to brains) sets the world up that way. Mind evoked on brains, functions, by design, to represent the external-real to the subjective; to produce veracious maps. This explanation tells us nothing about the mechanism of the relating. It removes not the mystery of the mechanism, but only the mystery of the facticity of its result. If God is real, then we would expect that mind (however produced) models the world because the same self-consistent God produced that world; the purpose (among them) of mind is to model the world to the subjective viewpoint. The mystery of how mind does this remains, but that it happens is not a mystery given theism.

So what arguments do realists who are not theists advance to explain or justify the veracity of the map? Mostly the problem doesn’t trouble them because the origin and nature of consciousness itself presents a bigger and encompassing problem. Realist-materialists mostly assume that, when we get a genuine reductive explanation for consciousness, the representation problem will take care of itself. We will know why consciousness produces an accurate modeling because (1) modeling is intrinsic to consciousness, and (2) we will know how it is that consciousness comes about. Notice that (1) has the same structure as the argument that God is redundant because the material world and its regularities are self-constituted; material being is a brute fact.

Materialists point to our survival as a species, and the progressive evolution of consciousness not only as evidence the map is accurate, but also is the reason for it. Suppose as consciousness evolved from the lower animals there were cases of both true and false (corresponding and non-corresponding) modeling not just as concerns individual sensory events but in the consciousness of the creature over-all. Those creatures having inaccurate maps are more likely to die early (perhaps because they fail to avoid some predator) and not reproduce. Those whose maps are more accurate, more corresponding, survive to reproduce. This doesn’t explain how it is that any accuracy is achieved in the first place. It doesn’t explain how a connection between the model and the world is possible, but it is a plausible account of the Darwinian ground of its achievement. Realists (without God) have not reduced the representation problem to physics, but this failure does not mean realism is wrong.

ANTIREALISM

Modern antirealism began with Kant, with his idea that the right way to do philosophy is to begin from within the subject. Antirealists and realists alike admit that, after all, all experience occurs within a “subjective arena”. Moreover, they agree that this subjective is a phenomenon “in the world”, that is in the broader context we might loosely conceive as the “totality of the universe”. That last notion, that there is, conceptually some total, that the idea is coherent, comes mostly from the realist side.

Antirealists today will mostly claim that not only can we not directly experience such a total (most realists agree) but conceptualizing a totality is meaningless (perhaps incoherent like a square circle), amounting to “begging the realist question”. There is some irony here in that most antirealists today are also materialists. They have to say that the subjective arena is simply “another component in the world” while remaining metaphysically non-committal about the nature and even existence of “a world”. Realism is first a metaphysics having epistemological consequences. Antirealists mostly abandon metaphysics (being unknowable) and fold what is left of it into epistemology. Since we cannot have knowledge of an outside, we cannot know if there is a total, an all of it.

The first historical result of that irony for antirealism was radical idealism. In the 18th century George Berkeley, “Bishop Berkeley” of Cloyne, took the antirealist idea and ran with it. Being a theist Berkeley was free to make an extreme claim; there is no “external world” at all. Not only must all experience be inherently subjective, but that was all there was to being in his ontology. The subjective is all there is and anything that seems as though it is external to the subject is put there, that is into the subjective, by God. God makes multiple simultaneous subjective experiences consistent. If I see a tree and you, standing next to me, also see the tree, it is because God put the tree into both our minds in just the way that it appears to us individually.

Obviously materialists cannot take this seriously, and even theists no longer give it much thought. The latter might acknowledge that it remains a theoretical possibility, but it seems far too improvized, even compared to the theistic solution to the reference problem. In today’s terms, radical idealism collapses into a variation of the computer simulation hypothesis in which God plays the role of the computer. This, in turn, collapses into solipsism. Perhaps everything I take to be another is only placed there for me.

By dropping God, antirealists face a philosophical problem far greater than the realist’s inability to explain representation; they find themselves with a well neigh infinite set of possibilities with no intersubjective mechanism to separate the sublime from the ridiculous. There might, hypothetically, be an infinite number of realist theories explaining our experience. But those theories, to be counted at all, must not only account for what appear to be external constraints, the behavior of the seemingly external universe, but also assume its metaphysical primacy.

By contrast, antirealist theories are constrained only by what is possible subjectively and this includes not only what appears to be external, but also such internal experiences as imagination, fantasy, fiction, and psychosis! Further, all the set of antirealist possibilities can be applied to anything. Not only might such analysis be fruitful in subjective-centered disciplines like art or psychotherapy, but also in inter-subjective phenomena like history, economics, and politics as these too exist to-the-subject only in the form of what makes itself known across the boundary of the subjective.

Antirealists since Berkeley claim there is an objective world independent of the subject and the subject (and subjectivity) is a part of this world. They also claim however that we cannot know in what this objectivity consists. All we can know is what it is experienced like from the inside, the subjective. Not only does this idea that “experience alone is knowable” apply to the external world (whatever it might be) but to the subject itself. We cannot strictly know our own subjectivity in any complete way either. Specifically, our experience, being what it is, we cannot get behind experience to find the subject of experience. In modern antirealist writing this comes out to everything, the seeming-world and the seeming subject of experience, emerging only from boundaries or horizons (the fact and content of consciousness) beyond which lies we know not what!

This (in a painful inverse of radical idealism) leads antirealists to suggest the possibility that behind the boundary there is nothing at all, that even the boundary is nothing and that behind it is less than nothing! Truth is like a rainbow, a phenomenon that has no ontological presence but rather emerges in consciousness from that which we do not see directly; in realist terms water molecules diffracting light. Not that antirealists can claim “there is nothing there” because after all they cannot know this, but what they can know (they suppose) is that “nothing at all” is a possibility, and if not nothing, then undifferentiated chaos, a universe of meaningless multiplicity about which we can say nothing. Structure comes only when the chaotic crosses the horizon of experience.

Homologous to the realist assumption that physics is self-constituting, consciousness, “whatever it is” is also self-constituting (tensions or torsions in, or exceptions to, the “unknowable multiplicity of (non-totalizable) universality (Zizek)). In another ironic twist having no homologue in realist circles, one of the possibilities for the explanation of experience in antirealism is realism (see Quentin Meillossoux “After Finitude” [2009])! To be sure antirealists cannot assert that realism is true, but they must accept that it is a possibility! Today’s Postmodernism is a direct consequence of these antirealist contortions. If truth can emerge from anything, even nothing, if truth’s foundation is entirely subjective, then perhaps there is no truth to be had at all, no ground for morality and so on.

But Postmodernism goes too far. Zizek points out that reality can be so chaotic (the universe at all levels of graining taken at the same time) or horrible (the holocaust) that subjective mind is overwhelmed by everything and cannot grasp anything. “Fiction has the structure of truth” (Almost the opening line of Zizek’s “Less than Nothing”) means that by fictionalizing “the real”, meaningful patterns invisible in the swarm of facts stand out. We experience their presence. This can happen also with “mistaken interpretations” of philosophical arguments or viewpoints, and also with art. These can unexpectedly reveal otherwise hidden insights or issues in what was intended by the author or artist.

Zizek is quite correct in that the “truths” revealed in this way arise purely in mind, but realists recognize that truth as such is a mental object, a part of the content of consciousness. The issue is whether or not what is experienced in the subjective, the pattern, “the truth” is represented by something identifiable in the external-real event to which it corresponds; of which it is a recognition, not an invention.

But what then is the antirealist response to this inverse of the representation problem? If realists cannot explain how it happens that our mental models are representative, how do antirealists explain, since we cannot know that our models are representative, why it is that airplanes fly? Realists point to such artifactual objects as airplanes (classical physics), and modern computers (quantum mechanics) as evidence sine qua non of the correspondence between model and independent reality. How, if we do not know in mind something of the structure of reality outside mind, do we explain our technology?

Antirealists here rely on what, in my opinion, is a pseudo distinction, one that only applies in mind, but cannot apply to a mind independent world, a distinction that amounts to “begging the antirealist question”; that between “working for-us” and “corresponding”. Our technology seems to work because it does successfully manipulate the horizon (qualia and such) that confines our subjectivity. To antirealists technological prowess does not mean that we know what is going on beyond the boundary only that what we experience is in line with our purposes (our intent for the technology) from our viewpoint on the inside.

Antirealism is to philosophy a little like String Theory is to physics. String theory has not brought relativity and quantum mechanics together despite 30+ years of trying. But it has resulted in many useful mathematical discoveries. By abstaining from talk of the external world (whose existence they nevertheless grant) antirealists have discovered much about the internal one.

Realist-materialists often have a difficult time with the idea that there are fundamental limits to what we can know, limits to mind’s ability fully to interpret material reality or mind itself. On the physical side, quantum mechanics is the quintessential example these days. Here it seems reasonable to believe that we can narrow the domain of that which we cannot interpret. But as concerns mind, there must be positive fundamental limits. Why? The antirealists understand this better than the realists. Mind is something in the world, but it is precisely that in the world in which we, the experiencing subject, are locked. We are inside a box. The box interacts with what is outside the box with sensory apparatus, but inside the box we experience qualia, an interpretive effect of sensory operation. We know the qualia conveyed to us, and in addition our purposes, emotions and so on, but not directly what lies beyond the boundary nor what exactly, on the inside, is having the experience.

Qualia are a boundary. Qualia are not the thing-in-itself outside the box. But they are what (to a realist) permit interpretation, knowledge, of that which lies outside the box while to an antirealist they are the only phenomena which we can know. For both realists and antirealists it is this interpretave experience that distinguishes the inside from the outside, but neither realist nor antirealist has any direct access to the “I” which experiences.

The I has nothing analogous to qualia by which it can interpret itself, that is distinguish itself from the content of consciousness. The “us”, our “I” is a horizon of the inside, the slippery object which we are fundamentally unable to analyze. To be consistent we have to say that, as with the “external world”, we cannot know anything about the “I”. Like the external world, the “I” might even be nothing at all. To all intents and purposes it might as well be nothing because, as with our senses, we experience not the thing-in-itself but only its boundary, the place where its illusion emerges into subjectivity.

Realist-materialists make the same invalid deduction with respect to the person that they do concerning the independent world. “There is nothing other than physics (the material world) because we can (a) explain all of physics and (b) not find anything other than physics with physics!” When we “look for” our center, our “I”, we do not find it. Since, from a realist viewpoint, we should find anything there is on the inside, there is therefore nothing there, no I. Antirealist-materialists are more sanguine about the external world because they “cannot say anything positive (meaning assign it positive, knowable properties) about it”. But with regard to personality, which if it is a positive reality must nevertheless be non-material, they make the same mistake as realists. Because we cannot find it (the person) there must be nothing there.

Realist-materialists might be mistaken about the completeness of physics, but at least their philosophical contortions stop there. Antirealists are not so lucky. Mind is an illusion (not material), and the person, the interior “I”, is also an illusion, a “hallucination halucinating a hallucination”. Zizek quotes this approvingly from Metzinger but goes on to say that Metzinger makes a mistake by not recognizing that a hallucination redoubled sublates itself, and from that dialectical process a reality (something positive — consciousness and self?) emerges.

From a realist perspective this is absurd. Zero “0” is a placeholder in mathematics. As a sign in the world it stands for nothing. Nothing plus nothing (0+0) or nothing times anything, even infinity, is precisely nothing. Everything that is real in the universe is either positive (atoms, chairs, “the universe”) or emerges from something positive: the rainbow from water vapor plus light, cold from a relative absence of [molecular motion] heat, and even evil from an intentional choice to commit error; an act positive not in the sense of “being good” but in the sense of being “a physical cause”. We need negative numbers for the consistency of mathematics, but they aren’t real. They don’t represent anything “in the universe”. If I add a negative three apples to a positive one apple (-3+1) I do not have negative two apples, I have precisely zero real apples.

In the human case, minds are directed by something intrinsically central to subjectivity. No we cannot find that center when we examine our own minds, but that we can examine (even partially) our own mind proves that the person is real, positive. Something exists that [partly] stands outside mind. The antirealist insight that there is subjective experience we cannot encompass because we do not and cannot stand “outside it” is genuine, but it does not mean that what we cannot reach is therefore nothing.

Purposeful intention is both real and positive. All of what is real, material and non-material alike, must have positive properties even if we cannot always say what, exactly, they are. Only in antirealism does something apparently come from nothing. The quantum vacuum (cited as counterexample by realists and antirealists alike) is not a metaphysical nothing. To realists, minds, be they the minds of lions chasing zebras or humans building airplanes, make a difference in the world, they cannot be nothing.

Mind is only the first step. Self-consciousness is possible only if something positive exists, at least partially differentiated from mind itself; within the box yet distinct from its purely mental content. Something positive is differentiated from the content of consciousness yet remains entirely dependent on the subjective arena for its expression. It is responsible for the recognition by that subjectivity that there is something both within and apart in it simultaneously. But the person is the end of the line. We cannot find personality directly because nothing stands outside it.

Personality transcends mind, views it as it were from an outside. But its difference or distinctness is not complete; partial. Partial is important because whatever personality is it experiences and expresses itself through mind. It is a pattern of some sort made of mind. This is why we cannot find a clean joint between mind and personality, but only a fuzzy one. Mind and the “I” together seamlessly constitute subjective experience! See my WHY PERSONALITY for a more detailed discussion of this.

Materialists of either realist or antirealist persuation both assert that free will is an illusion. The incoherence of this view is demonstrated by the impossibility of asserting its truth if it were true. Such assertion, given the subjective appearance of freedom must devolve into a Postmodernist rejection of all truth. If there is no free will then “there is no truth” that we can assert, because we are trapped in the role of “mouthpiece of the universe” having no idea whether what we [determinately] say is true or not. We might say that “it seems true to me”, but the me is an illusion, a hallucination, and after all we were deterministically impelled to say that too (see WHY FREE WILL and ARGUING WITH AUTOMATONS for more discussion).

If the Respresentation Problem is realism’s biggest challenge, antirealism’s seems much bigger. In theory the representation problem has a solution, but there is no end to the recursive possibilities possible in antirealism. Given the latter’s conviction that truth is only about the inside, within the arena of experience, the possibility of uncheckable recursion is fatal to the antirealist program. Realist-materialists might mistakenly reason there is no God, but the honest ones know that God remains a logical possibility. By contrast antirealist materialists (at least this is my interpretation of them) are ultimately forced to the conclusion that God, a real God independent of human experience not only does not exist, but cannot possibly exist.

In Realism universals (Realism does not deny universals) have particular instances. “Color” has Red, Blue, Green, and so on while particular modes (the redness of a particular apple) instantiate in particulars (the apple that has that shade of red — I follow here E.J. Lowe’s “Four Category Ontology” for example because Lowe was a Realist-materialist). In Antirealism universals can’t have individual instances. Particulars can exemplify universals for realists but there are no particularized universals in antirealism except the subject who is universal, whose experience is the only universal, for herself.

This “logic of the inside” reaches its apex for the subject, and subjectivity, itself. From every individual’s viewpoint, their own subjectivity, my universal for-myself is at the same time the ultimate particular. There is only one of that viewpoint in all the universe. There cannot, therefore, be an external “universal subject”, “a God”. A real, positively existing, God would occupy all separate individuality simultaneously. If God is “the universal person” then individual persons, that is an individual point-of-view, multiple in the universe yet universal for itself, would be impossible.

The person and her experience faces the outside which is nothing. She cannot find herself on the inside either, another nothing. From the gaps (horizons) between the nothings emerges our particular viewpoint which is also nothing and so comes from “Less Than Nothing” (the title of a Zizek book). Everything, because our experience after all makes up the all-there-is for each of us, is subject to this endless recursive descent of meaning. There is no stable social relationship because the outside is incomplete and the inside never fully known. Any evolving socio-political world, any particular example of it, has to crash against what cannot be known even on the inside and must inevitably conflict it.

Hegelian antirealists (my interpretation of Zizek) view history as an endless repetition, doubling down, sublation, and re-emerging with what was always there. History’s expression only seems new but is really nothing but a shift in perspective by the subject, herself emerging from the internal void as history emerges from voids both internal and external. Art of all kinds is subject to endless reinterpretation not merely (and sensibly) in historical context but intrinsically. There is no end to what art “can mean”. Nothing is necessary (everything contingent) yet the unfolding (and remember we are in consciousness) follows its own inexorable logic. The unqualified “real world” is unstructured, chaotic, actual-in-itself, potential-for-us. It is only the inside that structures it.

Capitalism is unique in the history of economic systems not because it is different and happens to be dominant in the present, but because it is the first of the economic systems whose “seed of destruction” lies not in its relation to an external environment but is built-in to it. Capitalism must grow forever (obviously unsustainable) and yet will not work at all without this excess at its core. The inconsistency in capitalism isn’t merely between it and its non-economic (political, social, ecological) environment (although it is that too) but is a fundamental part of how it works. Without that part of itself, its demand for endless growth and capital (self) accumulation it wouldn’t work at all. Remember though that all of this process takes place in and to experience, subjectively. In this realm, capital itself “comes alive” as it were and becomes “self serving”. Mind that produced it cannot fix the destructive ambiguities at its core.

There does seem to be something insightful in this, but only if its life is represented also in an intersubjective independent world. It is not capital’s “life within the mind” that makes it hard to correct imbalances or mitigate evil (gaming the system) but the fact (however it came about) that this subjective construct is mapped into independent-world effects that correspond to what we experience of them, often times economic disasters that bring misery to billions. All this is true of history more generally speaking. But it is a mistake to move from this insight to the assumption that the ambiguities and inconsistencies, both negatives in the sense that no ontological object exists for them, no positive qualities, are the core itself; that there is “nothing more” to the core than this negativity. Applied to history this comes out to there being only contingency; no such a thing as progress. Antirealist “intuitive logic” forces them to these conclusions, but they don’t seem so obviously true to most realists.

To be sure notions like progress in a moral sense are often rejected by realists as well and for the same reasons. Only as concerns the representations of physics do realists believe there is a, more or less, “immutable standard”; intersubjective agreement on theoretical implications coupled with experimental agreement.

Not surprisingly, sex gets some of the most convoluted analysis. Not the sex-act (though that too gets its share) but sexuality in general. Not-man is woman, but not-woman is an impossible universal and so not man. There are not two sexes but “one and a little more”, and so on. One is reminded of Freud’s quip (which Zizek quotes) “Sometimes a cigar is just a cigar”. The antirealist mistake is a failure to recognize that most of the time a cigar is just a cigar. In stereotypical Freudian fashion, sex gets tied into everything from itself, the sweep of history (it is not enough to note that there would be no human history without it), the entire edifice of art, and the very ontological foundation of being!

Language is the intersubjective expressive instrument of all that goes on in experience. Language is finite and imperfectly expressive. Fiction can reveal truth but also obscure it. In their examination of language (something after all we all experience subjectively), antirealists have subjected it to  more recursive convolutions than sex. Even the materialism of antirealist-materialism emerges, in experience, from the inability of lauguage to encompass the “out there” void itself merely a reflection (sublation) of the “in here” void. Chairs, or stars, exist, for example, because we can name (signify) them and what we cannot name can only be chaotic void. Mind is not recognizing patterns emerging onto its horizon, but generating those patterns which are otherwise “only void”. To be sure not all antirealist philosophers go all the way down with this recursive process, but the problem is there is no natural stopping point, no standard against which its theories can be compared. Nothing can be rejected. Any hypothesis we imagine is possible.

SUMMING UP

Realist physics has its own problems with indefinite speculation because, after all, the representation of the senses, even enhanced by instruments, doesn’t go “all the way down”. The string theory M-Brane universe of 11 dimentions is a fitting example. But there is a check on realism, at least in its dealings with the external. Speculation has to make predictions that are, at least in principle, testable. If it does not, it is never taken quite seriously. Antirealists can always say “the turning stops here”, but the next philosopher comes along and says “no there is one more turn” and this “one more” can go on endlessly. No check exists because whatever mind imagines can be taken seriously.

Antirealism has genuine insights. That there are limits to what we can know both inside and outside (and the latter for reasons more profound than merely scaling) comes naturally to antirealists. They understand why such limits are inevitable; a necessary (at least) core of consciousness. Modern realist thought (David Deutch, “The Beginning of Infinity” [2011] perhaps the present poster child) too often mistakenly elides this truth. Limits apply on the outside because the fundamental structure of the external-in-itself includes that which is genuinely indeterminite, irregular (and not merely beyond the possibility of measurement), and on the inside for the reason well understood by antirealists; we cannot get out of the box.

Arguing with Automatons

Introduction

There is no metaphysical middle ground between libertarian free will and automatonism. I stress the metaphysical here because there is phenomenological (psychological) middle ground that backs up into the epistemological. By “phenomenological middle ground” I refer to what I take to be most people’s every day experience with making choices. If you step into a taqueria and for a moment do not know if you “feel more like” chicken, beef, or pork, you think about it and choose one. We each make these (and many other) sorts of decisions throughout our day. In this process I (for I can in the end only speak for me) do not feel impelled by something, some combination of events in my past, to make one particular choice over another. I had chicken last week, so this week I’ll take the steak, or perhaps I liked the chicken so much I choose it again. Whether you are committed to libertarian free will philosophically the choice of chicken, steak, or pork, feels at least superficially free. Whichever choice you make you are at the same time aware that other choices (and so futures) were potentially open to you.

I will not further address this experience of phenomenological freedom because it is conceivable that you can genuinely believe you are free without actually being free just as genuinely believing you are Napoleon reincarnated does not mean you are Napoleon reincarnated. The issue then is not whether the alternatives appear open to you but whether they actually are open. Although you might have chosen beef or pork and have done so in the past, on this occasion something stemming from your past (indeed going all the way back to the big bang) determined that you would choose chicken and this determination was (usually is because otherwise the phenomenological room would also disappear) at least entirely subconscious if not in fact unconscious. On this occasion you were going to choose chicken just as on prior occasions there were determinations that led to your choosing steak or pork at those times. Automatons are entities that sometimes appear to make free decisions from a purely behavioral viewpoint, but which we know not to be free because we understand all of what leads deterministically to those choices; that is, we know all of what underlies the behavior both necessarily and sufficiently.

In this paper my goal is not to defend a view of libertarian free will as I have done that before here in this blog and other places. What does interest me here are two related things. First does it make any sense for a human being with free will to argue or debate with an entity who appears to be a human being but lacks free will? Second, if no human beings have free will does any debate or argument between such entities have any meaning or significance? I am thinking of the following scenario. Two human beings are having a debate. The thought of the first being is freely expressed through speech in a language that both know. That speech, having some meaning in the common language the other being grasps in her thought, leads to a free decision in the thought of the second being to accept the argument of the first being or to reject it and freely offer a counterargument of her own. Note the freedom involved here would entail the second being might have, besides agreeing or offering a counterargument, instead have chosen simply to be quiet and abandon the discussion among other options. What is crucial to meaning here is the respondent understands the semantic relation between the argument presented and her response whatever that turns out to be. “The semantic” is important here because the relation is not about the brain states of one party invoking brain states in the other, but rather subjective states of consciousness whose form and content do not resemble brain states.

The Argument

An automaton is a “state machine”. Some combination of parts each having various but finite numbers of states in which they can reside together determine what the automaton “does” at any given moment. The parts here can be mechanical, electromechanical, or of any other constitution that can express a “state”. Automatons today range from such trivial devices as automated floor cleaners to sophisticated computers in which software initially constrains possible “states” expressed in hardware; servomotors controlling a driver-less car or making chess moves on a game board. Every automaton begins in some first state when it is “turned on” and that state evolves in time from that point depending on what the automaton experiences in its inputs. Inputs include what it senses of the world’s response to its outputs (for example a chess move) which become further inputs. Not only do modern automatons “adapt” their behavior (within the range of mechanical possibility) by responding to their various inputs (given the potentials embedded in their programming), and that behavior can appear unexpected from the viewpoint of a human observer.

That these behaviors appear unexpected does not mean they are not fully determined (causally) by the automaton’s present state including all present inputs. In all the automatons we build from thermostats to self-driving cars and game playing computers we take this “ultimately determined” status for granted. We know that if we examine the machine’s workings in fine enough detail we will find exactly which combinations of states determined any particular behavior, that those states were sufficient to cause the behavior in question, and that those states were recursively determined by prior states (plus inputs) back in time to the machine’s first state. Because we know exactly how one state causes another we assume there is nothing more to the behavior of the automaton than its history of prior states. We assume that is, the automaton experiences no internal subjectivity. If two such automatons were to have an argument of some sort, a third-party would see what looked like our argument response between two humans illustrated above. But we have good reasons to believe that despite the behavioral similarity there is no subjective, semantic, understanding occurring in either of them.

Back in the 1970s there was an automaton named ELIZA. Today there are far more sophisticated automatons, but ELIZA is illustrative for my purposes here because it was specifically designed not so much to “be intelligent” but to mimic intelligence passing the Turing test. Simply stated, the Turing test proposed that a machine would or could be taken to be intelligent if in interacting with a human being, the human could not tell if it was interacting with a machine or another human. But the Turing test proved a little easy to pass under domain restricted circumstances and ELIZA was proof of that.

ELIZA’s domain was psychotherapy of the lite sort in which a therapist speaks one-to-one with a patient. Humans (students) were the patients and asked to talk (type) to their therapist.

Patient: I’m not sleeping well lately.
ELIZA: Have you any idea why?
Patient: I’m having bad dreams.
ELIZA: What are the dreams about?
Patient: My mother.
ELIZA: Tell me about your mother.

A simple program by today’s standards ELIZA found subjects, verbs, and objects in patient sentences and wove questions around one or more of them. If the program could not find any specific word to incorporate in its reply it output something more general like “why?” Most patients could tell that ELIZA was a machine but only after enough interaction that they realized ELIZA’s answers weren’t getting at anything. But initially, and in brief transactions, many patients thought they were speaking (typing) to a human being. But here’s where it gets really interesting for this argument. There came a point in work with ELIZA that some students, even knowing that ELIZA was a machine, not only continued to interact with it (some for long sessions), but reported experiencing therapeutic value! Some students said the sessions reduced stress and helped them think about their lives. The sessions “had meaning” in the broad sense, they had significance to the student.

The first question we want to ask is: were these interactions of meaning or significance to ELIZA? We assume not. We normally take it there is “nothing it is like” to be ELIZA, there is no consciousness there, no free will, no subjectivity. All of ELIZA’s replies are necessarily and sufficiently determined by a few hundred lines of code controlling the CPU and memory registers of a non-conscious automaton. One alternative view (taken by Chalmers and others) is there is something minimally “to be like” ELIZA, there is some subjectivity there though we cannot, from the human viewpoint “get at” what it might be like. Thomas Nagel (“What is it Like to be a Bat” 1974) deliberately chose an example (the bat) that to most people would have a subjective experience of some kind. Nagel’s argument is that it is in principle impossible for us to access bat-experience subjectively. His conclusion is taken to apply to any other subjective experience including that of other humans.

What would happen if we made two ELIZA programs interact? From a third-party perspective it would be a conversation between a therapist and a patient, that is two persons. But we know that this is not the case. We can explain all the behavior of both sides with reference to nothing but algorithms and programmable hardware, and we have good reason to believe that these are both necessary and sufficient causes of the observed behavior. We wouldn’t normally think to say that either side experienced any “therapeutic value”, semantic understanding or indeed had any internal experience of the interaction at all. Why not? Two reasons. One is that we do not impute any consciousness to ELIZA, and not having any consciousness, ELIZA cannot have and will at all. We normally take for granted that some consciousness is a necessary ground of any sort of willing. Will is only experienced, only exists, subjectively and never, like Hume’s cause, in the third person. My theme here focuses on the will so I want to stress the causal determinism (both necessary and sufficient) of the combination of algorithm and hardware is what robs the automation of anything that could conceivably be called “will”.

Now suppose we substitute real human beings for the two ELIZAs but stipulate that neither has a free will. The interaction is, in a manner perfectly analogous to “algorithm and hardware”, causally determined by states of the brains of the two humans. This causal relation is both necessary and sufficient to bring about every question and response there being no genuine “will” about it. So what is different about these two cases? Why (and where) can there be meaning and significance in the humans but not the automatons? The difference is the humans are (or could be) conscious – I stipulated only that they had no free will.

In the literature on free will and philosophy of mind one often finds that deniers of free will are not always deniers of consciousness. That is, although there is no genuine will there is experience, something subjective, and meaning arises in that arena. But consciousness itself is problematic for the same reason as free will. As Sean Carroll (“The Big Picture: On the Origins of Life, Meaning, and the Universe Itself” 2015) put it “thought can’t cause physics”. But if consciousness is real, then by some mechanism physics causes thought, subjectivity, and that should be equally impossible. There is, to put it bluntly, no more evidence in all of modern science that physics causes thought (subjectivity) than there is (from a third-party perspective remember the two ELIZAs) that thought causes physics. Consciousness and free will are two sides of the same coin.

If consciousness is real, and therefore experience can have meaning, then one must hold that physics causes [nonmaterial] thought. Rejecting this leaves only epiphenomenalism or eliminative materialism. The first makes experience (the subjectivity we experience every day) an illusion, while the second says it isn’t even illusory but nonexistent, something experience itself makes incoherent. Think of having a few orgasms in some clinical setting. The clinician asks you “which orgasm was the most powerful?” You say “the second.” The clinician, monitoring the behavior of every nerve in your body, says “No, my instruments tell me the first was more powerful.” The question comes down to who are you going to believe? The report of the clinician or the orgasm qualia you experienced? I stress here that it isn’t the orgasm, the measureable biological phenomena of nerve and muscle, but the subjective quality of the experience that matters.

The above example applies to qualia in general, but orgasms are particularly individual and subjectively qualified. It would be absurd to hold the third-party measurement had logical priority over the subjective experience. The quality of an orgasm is in its subjective experience and nowhere else. It would also be absurd to hold that an orgasm was illusory (epiphenomenalism) or nonexistent (eliminative materialism). An “illusory orgasm” is no more possible than a “square circle”. But none of this means there isn’t some brain state associated with every experience including experiences of thinking or choosing. If subjective experiences (think orgasms) are real, if they mean anything to a subject, there must be at least a logical separation between brain states and subjective experience. This is the gap so well described by David Chalmers (“The Conscious Mind: In Search of a Fundamental Theory” 1996 and “The Character of Consciousness” 2010), and that forces one to accept a property dualism of some sort.

In his 2015 book “Free Will a Philosophical Reappraisal” Nicholas Rescher asks us to consider that there is some brain state literally simultaneous with “the thought”. The question is not which is physically antecedent (and so causal) but logically antecedent and so initiating. Rescher is a materialist, so his scheme must work from the side of physics. He argues the relation between physics and thought is not causal in the normal sense that physics understands it. Instead of a cause he calls it an initiation. He makes two distinctions here. Initiations are atemporal. Rescher (a process ontologist) holds an “event view” of cause in which events unfold (cause) other events. What is important about all event unfolding is its temporality. Events have duration (however short or long) and “causing events” must precede result unfolding in time. By contrast, initiations are simultaneous with their physical expressions. Crucially they are not “events”. Rescher calls them “eventuations”. In Rescher’s view the eventuations go both ways. Brain states eventuate thoughts, and sometimes a certain class of thoughts we commonly call choices or decisions eventuate brain states.

Although Rescher does not try to resolve the mystery of the interaction metaphysically he doesn’t have to. What he shows is the reasonableness of the relation going both ways. If physics can evoke consciousness, then consciousness can, correspondingly, evoke physics. A second consequence of initiations is that there is some brain state just before a decision or choice in thought which is not sufficient to guarantee evocation of the brain state correlated with the thought. Of course the “thought correlate” is compatible with that prior state. It must be one of the following states that can evolve from the prior state. That it does evolve requires the prior state (or some other compatible prior state) but also the initiating thought which remember by Recher’s view is not strictly a cause. This is important because the neuroscientist need not accommodate any thought. One brain state (an event with temporal duration and so causal powers) is traceable backwards through (temporal) series of other brain states, the prior unfolding into the latter (as in ELIZA) without ever detecting the inflection point where a thought had non-temporal control.

Rescher’s distinction gives us the possibility of free will but at the cost of some logical dualism. If one accepts such a dualism then there is no unique problem with free will. But if one rejects all dualism in favor of eliminative materialism, then not only free will, but consciousness itself (and so subjective orgasm) is impossible. The only escape from such a trap is the ad hoc move of declaring that physics causes thought but not the other way around. There is no particular reason to believe this is the case however for even in this view, the basic metaphysical problem of the mechanism remains. If someday neuroscience does resolve the matter of how physics causes consciousness and demonstrates its sufficiency, it is reasonable to suppose they will discover at the same time how it is that consciousness [sometimes] causes (eventuates) physics.

My original statement “no metaphysical middle ground between free will and automatonism” has now come to the identity between eliminative materialism and automatonism. We have no reason to suppose that consciousness is real (think orgasm) and free will is not. Each must interact with physics in what might well be the same mechanism, some non-temporal cause not yet identified but that crosses Chalmers’ gap. But where does all this leave us on the meaningfulness of arguing with automatons? If you accept that consciousness is in some sense real then there is no choice but to accept some dualism. Once you accept that, there is no reason not to think that libertarian free will of some capacity is real also. If you reject this and insist on eliminative materialism then neither free will nor consciousness is real, and you must accept this in the face of that very experience that leads you to this conclusion. In short, the conclusion is incoherent and that means eliminative materialism is an epistemological nihilism.

Epiphenomenalism fares little better here. There are no epiphenomena in the physical universe apart (purportedly) from consciousness itself, no evidence that physics can cause epiphenomena. If consciousness is epiphenomenal so are its contents including judgments, thoughts, and everything built upon them; our mathematics and all of what we take to be empirical knowledge. Suppose we (and who is this “we” given the epiphenomenal nature of consciousness?) use our mathematics and science, build a real (not simulated) airplane, step into that airplane and it flies.

Is our flight experience something real (remember the orgasm) or also an epiphenomenal illusion? If illusion, what mechanism (the interaction problem) entails such a reliable connection between the illusion and the world? Physics produces an illusory phenomenon able, nevertheless, to make discoveries and use them to engineer devices that can only work if the discoveries (mental phenomena after all) match purportedly independent physics across time. Planes don’t only fly occasionally or by happenstance. Properly designed, built and maintained they fly every time. The only alternative to this extraordinary coincidence is there is no “independent world” at all.

What saves epiphenomenalism from metaphysical nihilism is that they must hold (being materialists) that it isn’t anything subjective (in this case discoveries and their connection to application) resulting in these engineering marvels, but brain states determined in an engineer’s deep past. None of what we take to be “subjective experience”, for example thoughts about airplane wings, can have any causal relation to the production and flying of airplanes. Experience tells us this is patently absurd. Rescher’s notion of initiation might help here but physics (and traditionally materialism) does not recognize any atemporal cause.

If eliminative materialism or epiphenomenalism is true then human beings cannot be anything more than complex automatons whose “initial state” goes at least as far back as conception. Possibly it goes back further, but just as an automaton cannot know what states of the world led to its being “turned on”, it would be impossible for humans to know one way or another if what fixes [illusory] choices goes back any farther than conception of your body.

Either way, it doesn’t matter because there is no you in anything that you do, choose, believe, or think. There is your body of course, but what issues from it is no different in principle than what issues from ELIZA or for that matter a robot floor cleaner. There is no reason for any conscious and free willed being to accept anything that issues from you as anything more than properly (let us say) formed propositions in the English language. The signs (words) carry standard meanings to the conscious recipient but the issuer counts for nothing being unable to have any “genuine opinion”, that is subjectively (though it may falsely report having such opinions), to consider one way or another.

Note that this does not mean that propositions expressed by automatons are not true. They may well be true, but if they are it is purely by chance that such truth is expressed through this particular channel compared to any other. There is no reason to credit the source other than to recognize the expression came from this source. The expressive vehicle has no “stake in the game”. It makes perfect sense to take the propositions of automatons seriously in the same sense that it makes sense to take a chess move by Big Blue seriously. But at the same time, it makes no sense to further argue or debate an automaton or give it credit for being clever. As clever as their behavior might appear to us (who have consciousness and free will) the cleverness (though not the truth) is imputed to the automaton by us.

Consequences

So what happens if you debate an automaton and as a result your argument and alters its behavior? Nothing is going on other than your output becoming its new input and deterministically re-vectoring the automaton’s report. There isn’t any mind there to change and arguing with it becomes nothing more than a game played with the objective of affecting the course of its behavior. One might interact with ELIZA merely to try to invoke a particular response. But note that an automaton (or other determined entity) changes our free minds all the time. How many books have I read whose contents have persuaded me to alter my opinions or beliefs? Of course we normally assume that a conscious free-willed person writes the book, but there is no reason this must be the case.

Being free willed I allow the arguments (by accepting as valid and good and choosing to alter my beliefs, behavior, motives) in the book to have the impact on me that they have. Linguistically, crediting the book with “changing my mind” is merely (usually) a proxy for according its author that credit. But the book is neither conscious nor free willed and yet the book, by my reading, and not its author, is the proximate cause of my change of opinion.

At the end of the day then debating an automaton simply makes no sense. Winning such a debate is like winning a chess match against Big Blue. On the conscious side it might be satisfying and it provides new inputs to the automaton, but we have not thereby altered any mind. No person acknowledges any “good argument” on our part. If the automaton has a designer she might come to recognize something novel about my argument. I might be impacting some mind at second order here, but among the foundation pillars of materialism an insistence there is no designer.

So what do we do with an entity who looks just like a free willed person but claims to be an automaton? There are three possibilities: 1) the entity is lying, 2) the entity is mistaken, and 3) the entity is an automaton. Notice the three alternatives concern only the status of the free will claim. An automaton can produce true propositions. Theoretically, a mind might fruitfully engage with an automaton, even learn something from it. But fruitfulness is precluded if the subject at issue is or inevitably involves the no-free-will claim. As it turns out, most philosophical issues are entangled with the no-free-will claim. Obviously metaphysics and epistemology touched above, but also ethics (any subject having any socio-political import; anything on our world involving interaction between entities that look like people) and aesthetics (can an automaton experience beauty?); all the classic philosophic sub-disciplines.

If the entity is lying there is no point in arguing because we do not know the motivation behind the lie and thus even a knock-out argument serves no purpose. If the entity is an automaton then again there isn’t any point arguing because no argument exists that would make the truth other than it is. Big Blue is an automaton no matter how hard we try to convince it otherwise. Indeed we might cause Big Blue to report that it isn’t an automaton, a mistake by the machine. Reporting free will (or consciousness) when none exists does not change the fact of the matter. We have done nothing more than caused a deterministic system to mis-adapt in a small way, a Pyrrhic victory if ever there was one. Big Blue’s mistaken report need not affect its chess playing skills.

That leaves “being mistaken” by a conscious entity. Here at least there is, presumptively, a mind to be changed. In theory, some argument can affect it, could make the conscious entity recognize that it must in fact be free willed. While possible, such an argument isn’t likely to be found. Why? Because the individual concerned believes the falsehood (often asserted by authorities like physicists and philosophers) “there is nothing but physics” and “thought cannot cause physics” (even bearing in mind the causal distinctions made above). Ironically many of these same authorities see no inconsistency in physics causing thought. We cannot prove the reality of free will or even consciousness in any logically rigorous way any more than we can disprove it. Human beings (I speak biologically here) who claim “no free will” believe this (typically) for metaphysical reasons. If physicists are correct as far as they (all science) can legitimately claim and there is nothing but physics to be found by physical means, then the only possible evidence of the reality of consciousness and free will is what we experience subjectively in the daily business of our lives.

Either we assume that human beings on Earth who deny any free will are mistaken by intellectual error, a choice (free willed) to accept a falsehood, or we take them at their word and they are not, in fact, free willed. If we take the second alternative, continued interaction is nothing more than a game played with a sophisticated ELIZA. Of course in our real world, some mix of the these is also possible. Some of those who report lacking free will are simply mistaken, while others might genuinely lack it. But all of this only matters to free willed human beings on one side or the other. If a free willed being mistakenly believes she has no free will, she might be enlightened, liberated, saved by our interaction with them — however unlikely this is. If the being on one side has no free will, really is an automaton, arguing with it about this is a waste of time.

By contrast if there is no free will on either side, then everything is a “waste of time” because all interaction would be meaningless; epistemological nihilism. There would be nothing “to know”, only what determined physical behavior, a process physics does correctly recognize as purposeless and therefore also metaphysically meaningless. Why should all of us automatons bother to do anything at all? The answer should be plain. The capacity to ask that last question cannot issue from a true automaton. To an automaton, the answer must be determined, perhaps “to maintain its existence”; not a rationale or purpose (of a mind) but a blind switching of state. To question the meaningfulness of existence presupposes some subjectivity whose experience, and so existence, it is. If subjective experience is real then physics causes (perhaps atemporally initiates as in Rescher) thought, and though obscure there is no a priori reason why thought shouldn’t cause (initiate) physics by the same mechanism.

Information, Life, and the Big Bang

selfie

In 2014 William Dembski published “Being as Communion: A Metaphysics of Information” what he calls (in the introduction) a capstone on a trilogy that began with “The Design Inference: Eliminating Chance through Small Probabilities” (1998) and continued with “No Free Lunch: Why Specified Complexity Cannot Be Purchased Without Intelligence” (2001). In the first two books Dembski spends his time building an argument about the unlikelihood of even simple life’s “information content” assembling itself accidentally on the Earth of some 3 to 4 billion years past.

Considering the Earth could only have supported any conceivable life as recently as 4 billion years ago, life appeared rather soon after supportive conditions developed. Dembski concludes (and you can read the books to follow the math) the probability of that much information assembling itself in that little time is about 1 x 10^-150. The same basic principles hold true for life’s evolution to its present forms adding an extraordinary amount of extra information along the way. Dembski understands Darwinian mechanisms. He carefully evaluates their capacity to assemble such an information pyramid by accident given the possible range of chemical interactions that occur among all the molecules of the nascent biological Earth on up to the present day. He shows again that it is incredibly unlikely for evolution to have been nothing but an accidental combination of mutation and selection.

In his third book Dembski goes on the offensive and focuses not on the unlikelihood of accidental life and evolution to present forms, but its impossibility. He does this by adding to his previous analysis a principle understood and accepted by today’s physics community; “Conservation of Information”. The concept is simple enough. A given system of mass-energy with boundary conditions (including energy flow) cannot express more information than was put into it somewhere.

To see how this all plays out over the history of the universe is the purpose of this essay. Dembski misses something important by leaving open when exactly the information needed to specify life (and next evolution) is added. Dembski happens to believe in a Christian God so he has no problem with the idea of information added to the world at life’s origin. But he leaves open the possibility the information comes not from God, but perhaps aliens. Also open is the notion the necessary information was there at the beginning, at the big bang, leading to a panpsychism, or for that matter that we are living in a computer simulation (another version of aliens) adding information as the code grinds on.

What Dembski misses (or fails to appreciate properly) is that the fundamental discoveries of physics point to a late introduction of the information needed to assemble genuine life. It is my aim here to fill in that gap. Beyond this, Dembski goes on to note that our only experience of information-creation or addition to the world is our own intelligent designs. If information is conserved, and its only source is intelligence, the universe’s initial information must come from some intelligence somewhere. Again this leaves open the possibility of super-aliens, computer simulation, or God. If Dembski is right that information is conserved, then either the universe’s information originates in some intelligence or it was all there from its beginning. If it was there from the beginning, if it was a part of the physical universe at the big bang, where in physics is it found? Does what physics finds at the beginning provide for everything from stars to conscious observers?

Information as understood by physics is of three types, Shannon information, Kolmogorov information, and semantic information. I review these more extensively in my books. A brief summary will do here. Information in all these forms is exclusionary. A hypothetically information-less collection of matter energy, displaying no behavioral regularities, contains within itself a well-nigh infinite potential of future possible states. But there is no such collection because the nature  of matter-energy and the regularities we observe depend on information. Information, beginning with its first expression in “natural law”, restricts present potentials and future possibilities. Our universe, its fundamental material regularities, allows everything from black holes to consciousness, but the possible future states of a present state anywhere in the universe, or for the whole universe, are not infinite.

On a cosmic scale, the specific history of our universe cannot have been much different than it was given its initial information. A stable universe of undifferentiated energy, mint-jelly, or Boltzman brains is ruled out of genuinely possible histories. Information configures matter-energy in some way. This is an important characteristic or property of information, more particularly its causal effect on matter-energy, and is understood and accepted by modern physics.

Claude Shannon developed formula for computing the quantity of information that could be unambiguously (clearly received) over a communication channel having a certain bit rate (number of detectable state changes per second) and some amount of noise. No information channel is noise free in the real world thanks to the second law of thermodynamics. Shannon information isn’t about any particular message, but about how much message a channel can carry. Capacity might be measured over time as it is in digital communications and radios, or in some other measure, for example the length of a DNA segment or a chromosome. The exclusion principle comes in trivially here. A particular message on a channel excludes other messages on that same channel at the same time or in the same place.

Kolmogorov information is about the complexity of a message. The message BBBBBBB is less complex than the message BCADFGE. We can re-write the first as 7B while the second requires all 7 characters in the correct order. Notice that the message FGCBAED is a different message but has exactly the same complexity as BCADFGE. Something like CCCABBF is intermediate in complexity because 3CA2BF requires only 6 characters to specify a 7 character message. Again we note the exclusivity property. Any one message of any complexity excludes all others.

Semantic information concerns what a message (information) means. Normally associated with human mind semantic information is plausibly characteristic of consciousness in general. Life, even without consciousness, displays metaphorical meaning. This meaning is metaphorical because life doesn’t apprehend it. Rather meaning is imputed to life by consciousness, and seemingly always by human consciousness. Importantly to physics, there is no semantic meaning, metaphorical or otherwise, in nonliving, material process. The purposelessness of material mechanism reflects its lack of semantic meaning. “Purposeless mechanism” and “absence of semantic meaning” are two sides of the same coin.

Information expresses itself, one way or another by configuring matter-energy whether the flow of electrons on a wire, persisting patterns, or a recognition of significance (meaning) of a configuration to consciousness. We are now in a position to understand the connection between information, life, and the big bang.

Information, the potential-reducing patterning of some chunk of matter-energy, expresses itself differently depending on boundary conditions, and energy flows. Boundary conditions reflect information in the wider chunk of matter-energy that has causal input on expression in the bounded chunk. Theoretically that would be everything in the past light cone of the inner most bounded chunk, but this is often so vast a space and time that we ignore most of it. The word ‘chunk’ here refers to the matter-energy of some particular region of space and through some bounded time. Every expansion of view to wider and wider spacetime chunks encompasses more matter-energy configured by information whose expression is in turn influenced by even wider chunks. ‘Causal effect’ is a function of forces, fields, with which matter-energy both brings about and with which it interacts. For my purposes, it matters not whether we view matter-energy as the product of fields (as in quantum field theory) or fields as a product of more fundamental matter (charged particles). Both views rest on the same fundamental information.

The first boundary conditions of our universe are the particular qualities of the forces describable in information theoretic terms. These forces restrict what can happen at any given “next instant”. When we gaze into the heavens what we see, the stars, galaxies, clusters, clusters of clusters, interlocking streams of clusters going on as far as our telescopes can peer. At the largest scales, distribution of these substructures appears random, but just inside the largest scale, there is clearly an expressed arrangement. The matter-energy of the universe is not distributed randomly at all scales. Our particular arrangement, can be described as a measure of complexity; Kolmogorov information. That state, any given “state of the universe”, changes into new states. The entire universe has a capacity, a limit, at which the evolving information expression advances. There is a limit to the rate at which change in the universe takes place. The universe has a Shannon information limit.

Cosmologists and physicists have long recognized the structures of the universe are, over-all, a natural outworking of a tension between positive energy expressed as temperature and pressure and negative energy known by its more common name, gravity. A cold cloud of hydrogen gas and dust floating around in space has more entropy than the star which eventually forms from it. It is gravity (negative energy) that reduces entropy in the gas cloud by consolidating it, restricting the freedom of its individual atoms to be anywhere in the much larger region of space that was the cold cloud. At cosmic scales, gravity is the great reducer of entropy. It does this by folding space around mass. Mass migrates inward (falls) toward the center of the folding which happens to be always what we call the “center of gravity”.

Taking entropy out of a system like this makes it more difficult for photons to escape it. Folding space compresses electromagnetic forces (constraining photons) heating the contracting gas producing more rapid particle motion, raising temperature, and increasing pressure. Eventually the gas heats up enough that fusion occurs and the resulting release of positive energy balances ever-present negative gravitational energy. But why does the balancing out occur here at this point? Why isn’t gravity strong enough to overcome fusion and keep folding space until a black hole forms more or less immediately?

The balance occurs at fusion, and gravity and pressure combine to make all the structures of the physical universe, thanks to the cosmological settings. The causal regularities we call “natural law” rest on the settings. The settings (there are some 20 of these seemingly arbitrary values among them the “cosmological constant”, the value of the “Higgs field”, the “fine structure constant”, and the “proton-electron mass ratio”) limit the ways in which matter-energy can interact. The particular interactions that occur are a reflection of the settings under boundary conditions holding at any given place and time. The settings are the minimal information present at or shortly after the big bang.

The star balanced at fusion expresses the same information as the cold gas cloud from which it formed. Both are deterministic expressions, patterning in behavior, of the same settings. At the opposite end of the size scale from stars, at the building blocks of matter (the fundamental particles of the present Standard Model) to molecules the same settings restrict behavior. At the small scales the important forces are the electromagnetic (molecular scale), and the strong/weak forces (nuclear scale). The same settings pattern matter on a different scale from the cosmological under differently relevant, microscopic, boundary conditions.

When mass-energy at a macroscopic scale is somewhere in thermodynamic equilibrium its state expresses the information present in the settings under that equilibrium. For the expression to change, to evolve, boundary conditions must change. That change rests causally on the flow of energy through the system. Change is also inextricably bound up with time. The seemingly simple notion of time is anything but simple. Is time something fundamental, perhaps even more fundamental than space (Unger/Smolin “The Singular Universe and the Reality of Time” 2014), or does it emerge from (and amount to) an averaging (as temperature is an averaging of molecular velocity) of the change in the quanta of space (Carlo Rovelli “Things Are Not as they Seem” 2016)? Does time exist at all, perhaps being nothing more than a meaning (semantic information) consciousness associates with measuring the rate of change (Julian Barbour “The End of Time” 1999). For purposes of this essay, nothing depends on this controversy. Time, one way or another, is an ingredient of every boundary condition and energy flow throughout the universe at all scales.

Significantly, when change occurs ordered patterns emerge. A star is ordered in this way compared with a gas cloud We note the same phenomena in columns of bubbles rising in the simmering water in a pot. The ordering in all of these cases is the result of a coupling between the settings, the boundary conditions, and energy flow. For my purposes below, I lump energy flow into the boundary conditions but the reader should always be aware that if changes in information expression are occurring, energy is somewhere flowing through the system. There are a few scientists who claim this emergence of order is enough to explain the eventual appearance of life, but this cannot be true. As I discuss below, life exhibits a new kind of ordering that never appears in non-living phenomena; and ordering requiring information not present in the settings directly though of course it remains consistent with them.

All the phenomena of the universe from the layout of the galaxies and down to the behavior of atoms in crystals and amino acids directly express cosmological settings under different boundary conditions, and these in turn also rest on the settings. The settings are the information present at (or within a second) of the big bang. They are information because they do what information does, they restrict or exclude possibilities by constraining what they pattern. The behavior of quarks, protons, neutrons, electrons, or the effect of gravity, isn’t random. The settings restrict the values of the forces and those constrain the behavior of everything else from quarks to superclusters.

The limits, patterns of behavior, vary as conditions change, the changes themselves “caused” (some would prefer “unfold into”) by those same regularities. Two seconds after the big bang all the settings were already in place. The strong, weak, and electrostatic forces had to exist as they now do for there to come into existence protons, neutrons, electrons, and a few nuclei of helium and lithium. Given the enormous pressures and tempretures of the environment (boundary) of the big bang in its first seconds, the building block particles where the expression of the settings. Given 14 billion years of evolution, we have the universe of today, an expression of the same settings. Up to a point.

If the Conservation of Information theorem is correct the information respresented by cosmological structure or molecules had to be put into the universe as it has evolved over time, or it had to be there at its beginning. Cosmologists today mostly believe that this information was in fact all present from the beginning, or at least within a few microseconds of the big bang. Physics and cosmology has convincingly shown the settings plus gravity explain the present structure of the cooled down universe. Granting that all of this information was present at or near the beginning from where did it come?

At first cosmologists thought perhaps the values had to be what they now are; not arbitrary but rather forced out of the boundary condition of the big bang. But a hundred years of theoretical effort to derive them has failed to prove the necessity of these particular values. The now fashionable answer is the values sprang (quickly evolved) into their values purely by accident, by sheer coincidence. Recognizing the improbability of this, cosmology and physics have spawned many theories of multiuniverses (Max Tegmark “Our Mathematical Universe” 2014) in which the settings take on all manner of random values. The idea is that given billions of such universes, it is not inconceivable that one would occur in which the settings took the values we observe. That they did so here makes the eventual appearance of observers possible and it should not be surprising that observers find themselves existing in such an unlikely universe. This idea, called the “Anthropic Principle” (Brandon Carter Krakow symposium 1973, Barrow and Tipler “The Anthropic Cosmological Principle” 1987), must be at least trivially true. Since we exist, it must be possible for us to exist within the constraints (remember information restricts possibilities) of the cosmological settings.

Of course there are plausible “intelligent alternatives”. God might have constrained the settings to obtain the physical universe we occupy, a physical universe supporting eventual life and consciousness. A few honest physicists have noted the unlikeliness of the settings would not be surprising if there is a God. Besides God, the intelligent alternatives coming from science have tended to pure science fiction speculation of super-aliens (effectively demigods) or perhaps computer simulations (also implying super-aliens). Such speculative alternatives all involve beings like ourselves only having far advanced cognitive abilities and technology. Such beings either live with us in our universe or inhabit their own universe outside our own. Either way, all the cosmological origin questions remain. But multiuniverse theories require only more physics; perhaps other physical universes of some sort. This is why the science community prefers such otherwise unverifiable speculations. But they are not better explanations. They do not, for example, extend to consciousness very well.

There is something more to notice about information re-expression based solely on the settings and evolving boundary conditions. All of these expressions, that is everything governed primarily by gravity as the source of negative energy, electromagnetism, or nuclear forces are repeating structures. Every proton is identical to every other proton, and all the galaxies, while differing widely in specific shape and size are gravitationally bound rotating collections of stars very often influenced by a large central black hole (dark matter is a part of the boundary conditions forming and maintaining these structures). If you consider any given cubic meter of a star’s interior at some distance between its center and periphery, it is much like any other cubic meter of that same star at the same distance from the center.

At almost the opposite end of universal size scales, the most informationally complex structures are homogeneous crystals and relatively simple organic molecules like amino acids which themselvs will form crystal structures under the right boundary conditions. There is a large negative entropy difference between a freely floating gas of hydrogen, carbon, nitrogen, and oxygen, and an amino-acid composed of those same elements. But that reduction, purchased in the molecular case with the energy of electrostatic bonds, is nothing more than a structure that arises automatically thanks to the settings under particular boundary conditions. From the crystallization of water (ice) to the formation of amino-acids, as with gravity, entropy reduction is associated only with the production of regular repeating structures whose variation depends solely on the nature of the settings and boundary conditions which are themselves the result of the setting and their own larger-scale boundary conditions.

This situation changes dramatically when we look at life. Galaxy formation, stars, and amino acids are an immediate response to entropy reduction caused directly by gravity or electrostatic forces under specific conditions. Once any of these arise they become stable. Only changing boundary conditions alter their stable states. Even dynamic but presently stable stars are in a stable equilibrium condition with pressure balancing gravity.

But living systems differ from any nonliving information expressions in several ways. Their stability is never merely a simple equilibrium, but rather the product of many interactions dynamically reducing entropy in the living organism over all. Of course living processes cause entropy increase in the environment, the boundary within which life operates, and there are living processes that spend heat in support of neg-entropic mechanism. Life exhibits a persistent battle against entropy and is never in internal equilibrium. If a living organism comes to complete equilibrium, or its entropic activity dominates, the organism dies. More importantly, life’s neg-entropy mechanisms achieve their effect not by the simple surrender to the consequences of the settings but rather to active mechanisms that map or translate information from one form into another. Living systems are filled with little engines that map information from one form into another reducing entropy in the system over all as a by-product. No comparable mechanisms exist in the nonliving cosmos.

The most familiar of these living mechanisms is the multistep interaction chain, associated with many intermediate structures themselves built up out of the same process, of mapping information in DNA to proteins. Obedient to the Conservation of Information theorem, this creates no new information. Rather, information is mapped from one expression to another. But the mechanism itself, a mapping engine, is new. None of this works apart from the limits imposed by the settings. But unlike stars, life’s entropy reduction is not a direct outcome of the settings, but of an entropy reducing transfer of information from one form to another.

The complexity of life frames a further limit on the space of possibility within the restriction imposed by the settings. It amounts to new information besides the settings alone. A protein’s biological functionality is not merely the result of its electostatic forces, but also its physical shape. True, the shape is the result of electrostatic forces, but an identically force-balanced molecule of a different shape will not work. Many differently shaped molecules might have identical force balances. The biological activity of a particular shape is a restriction not found in the settings alone. Life’s information is a restriction on top of a restriction and that demands more information. Where did this more come from?

Once again science, this time biology down through chemistry to physics, declares that it was all, like the settings, a lucky accident. Yes, they admit, unlikely, but not impossible and if it hadn’t happend on Earth, we would not be around to comment on it. In his first two books, Dembski explains just how unlikely such an accidental assembly is; thousands of different translations, hundreds of thousands of molecular arrangements, functioning as an integrated system, a living organism. In his third book Dembski argues that the information difference between nonliving processes and the simplest conceivable life (simpler than anything we find on Earth today) could not possibly come to exist accidentally. If life’s arrangement cannot be a direct product of the settings alone (the only information present in the big bang and throughout the evolution of the nonliving cosmos) its accidental appearance would be a violation of the Conservation of Information principle. What Dembski misses (at least I do not remember him mentioning it) is that life’s entropy reduction mechanism, complexity translation, is nowhere else exhibited in the interactions of the nonliving cosmos. From intergalactic clusters to amino acids none of the accumulated information is carried through translation mechanisms. It is all the immediate expressions of the settings under specific conditions.

For science to declare the one “life origin” event we know of is an accidental product of the settings plus boundary conditions directly is question begging and most scientists know this. “Accidental” is not a valid generalization from a single observation. Even if life on Earth originated on Mars (some cosmologists do assert this is a possibility), the question of how Mars’ life began still stands. Plausibly however, life-harboring planets around other stars are effectively isolated from one another. Life on such worlds originates and evolves independently.

What a discovery of genuine life on the planets of other stars would mean depends on what we find. Finding something indisputably alive but much simpler than the simplest life on Earth, would lend credence to the view that initial assembly might be accidental. Perhaps some life is so simple (something true also of long vanished early life on Earth) that it is not so unlikely after all. But if what we find on one or even dozens of other worlds is that all life is complex, different perhaps but on the same order of complexity as the simplest life on Earth, the hypothesis of “accidental appearance” gets all the more problematic. If, as Dembski claims, the chance of life springing into being accidentally on Earth is 1 x 10^-150, it is half as likely to have happened twice, let alone multiple times.

The rest of Dembski’s argument is straightforward. Human beings, observers in the universe, know of (that is experience and observe) only one source of new information in the universe; intelligent agency. For materialists to claim that this too, that is what we experience subjectively as intelligent agency, is nothing more than an outcome of the settings and boundary conditions, begs the same question as regards life. The “only example one has” of anything cannot be the ground of a valid inductive generalization. If the only life we ever find is complex enough to be highly unlikely there are only three possibilities. The absurdly unlikely happened, there is something fundamental that we are missing in physics, or life’s information came from the outside, from intelligent agency. In all my writing including this essay I have taken for granted there is not something fundamental missing in physics.

Physics may not be finished thanks to the problem of unifying gravity and quantum mechanics, but it has nailed a few fundamentals. It has adequately dispensed with the idea there is an “invisible force” that pushes physical regularity toward the assembly of living information. We find nothing of this in classical physics or quantum mechanics. If physics is correct as concerns its own causal closure, then life’s information had to be added at a place and time when boundary conditions were supportive. If some intelligent agency acted at life’s origin (perhaps on many worlds) then the same agency’s action, to fix the settings, at the big bang would not be at all surprising. The settings are fixed as they are in support of [eventual] developing boundary conditions conducive to life’s origination.

This notion must also apply to life’s evolution on Earth to the point of emerging consciousness, and in particular a personal consciousness (discussed at length in other essays on the blog). Over a mere 3 billion years an amazing quantity of new information (Kolmogorov complexity) assembles from primitive cells to organisms having subjective experience. Subjectivity at least begins with the higher animals, but it makes the transition into “observer status” only in human beings. Animals observe their environment in the sense of integrating sensory experience in a subjective gestalt. But being an OBSERVER implies more than mere observation, it implies recognition of meaning implicit in observation but not of the observation as such. This brings me to final consideration of semantic information.

Semantic information, taken most broadly, is prelinguistic, but not preconscious. A lion easily distinguishes between a zebra and the tree next to it. It grasps the zebra is potential food and the tree is not. The discrimination between zebra and tree has meaning to lion consciousness. Given memory and subjective experience an association links ‘zebra’ to the relief of hunger. Semantic information is transferred not by translation from one physical carrier to another, but from some such physical state to a subject. Meaning is meaning to a subject. Compared to biological information, semantic information is one step further removed from the settings. Many discrete sets of biophysical states ground a particular persisting consciousness, while different conscious experiences follow from similar biophysical states. Semantic information is largely independent of the physics underlying it and exists only to consciousness.

The uncoupling of semantic information from physical information continues in human consciousness. A zebra means [potential] food to a lion whether it is hungry at the moment or not. Both lions and humans apprehend meanings in this way, we are after all animals. But human beings not only apprehend meanings, they also abstract and evaluate them. Abstraction and evaluation combine to suggest meanings not immediately apprehended. This (and our volitional power to control our bodies) underlies our capacity to put new information into the world, literally to pattern matter-energy restricting its future potentials. Humans alone are capable of adding information, arising in subjective abstractions, to the world. Lions are not. We create art, and airplanes. Flying airplanes are like biological activity in the outcomes of information mapping engines. A successful mapping creates not only a biologically active molecule, but one that functions in a role specified by biological demands. A flying airplane signals a successful combination of semantic information and physics (purposeless mechanisms resting on the settings) whose proper role is specified by subjective intent to build a flying machine.

In a living cell there is nothing in the chain of events from DNA to a shaped protein that relies on anything other than the basic forces whose fundamental information, present at the big bang, is the settings. In this case, the electrostatic forces are dominant, but everything has its effect on the outcome. There does not appear to be anything in life that originates outside the physical world. As with the settings, once information is put in somewhere, life’s day-to-day operation exhibits nothing but outcomes explained by the forces (settings), and boundaries now including life, that cell, itself. But life’s delicately balanced self-maintenance does not address the issue of how its information originates. If the Conservation of Information theorem is true, then not only was its accidental assembly unlikely, it is impossible.

Individuals are free, of course, to believe life’s origin and evolution was accidental. But the argument that they were nothing of the kind is clearly plausible, even reasonable compared with much speculation from materialists. When we arrive at human beings, a new power springs from life through consciousness. Not only is there a mapping from some physical “state of affairs” to a meaning apprehended in consciousness, but uniquely, humans can map abstract meanings from consciousness to the world. Abstraction capable language marks the final separation between information and the settings.

The word ‘palo’ in Spanish means ‘tree’ in English. Either might refer to some particular tree or to the class or kind ‘tree’, and both are equally compatible with the settings and boundary conditions up through all of biology. All human languages are of course compatible with human biology everywhere on Earth. Expressing a single abstract meaning in different languages demonstrates the complete decoupling of semantic meaning from the settings. Completing the decoupling begun with life and continued in animal consciousness grounds both human free will and our power to create information.

This capacity, the free-willed intelligent creation (by arrangement of matter-energy) of new information, demands new information. If everything that happens in the universe expresses information, such novel power rests on information not previously present; information added not to matter-energy directly, but to consciousness. I go into what this implies in more detail in my books and the blog essay “Why Personality?”

All the information from the settings to life, supposing they come from outside physics, might conceivably (however implausibly) be the work of aliens, or perhaps we live in a computer simulation. Consciousness poses a special problem because unlike the universe and life, it is plausibly both real and nonmaterial. A corollary of life’s physical nature is that living process isn’t intrinsically conscious. Nothing about biology, however complex, suggests an emergence of subjective experience. It isn’t clear that any subjectivity can emerge from a causally closed physics; not even accidentally given infinite time! Human consciousness poses an additional problem. Even the highest animal consciousness does not display an ability to configure the world in novel ways based on new meanings conceived first (and not merely apprehended) in consciousness!

Human beings can shape the world based on thoughts whose origin has little direct connection to immediate sensory experience or memory. Of course our creative thinking includes apprehended meaning. But human creativity goes beyond experience to first postulate new, associative meanings, and then test their validity (truth content) by configuring physical subsystems that function (like shaped proteins) in their intended roles. Art, philosophy, and technology are all predicated on the validity of meanings originating in consciousness.

If aliens did this, from life (at least) to subjectivity capable of original creation, directly or in a computer simulation, they would stand in relation to us much as religion’s claims for God. Not entirely, for it is not an entailment of the alien hypothesis that aliens be for example omnipotent. If however we live in the matrix, a computer simulation, then omniscience, omnipotence, and omnipresence within the context of the program are reasonable inferences.

If the aliens are a product of this universe, the matter of the settings, and how the alien life started and evolved, appears. The alien hypothesis settles no philosophical issues. If aliens created the universe itself, and it is not a simulation then their universe must be something outside, apart from the physical as we see it from inside our universe. Even if one insists this outside is physical it cannot be “our physical”. There must, in this view, still be something outside our universe. But none of this matters because if any of these speculations are even remotely true, then something or someone added information, at least beginning with life if not the big bang, to the universe, our universe! It doesn’t matter if the agency is divine or not or if the information came from aliens inside or outside the universe. It isn’t necessary to assume that this agency must be purposefully intelligent. But evidence at least suggests that it exhibits all the characteristics of purposeful intelligence as we observers experience it.

If any of this speculation is true, physics must still give up the idea that “no such information came from anywhere”. There is some irony here. The speculation taken most seriously by the materialist community is that all we know as our world was genuinely an accident; precisely the “no information from anywhere” hypothesis. The irony is that this hypothesis is the one least supported by all the evidence, even the purely material evidence of life. Life is the first, partial decoupling from the settings. That decoupling depends on information not present in the settings. If the Conservation of Information theorem is true, life’s information had to come from somewhere other than physics.

There is nothing in physics, nothing in the strict causal closure of the physical that is incompatible with information coming in from the outside. Purposeless mechanism (a valid insight of physics) and purposeful information added by an intelligent, at least intelligent seeming, source are not incompatible. This is almost a trivial truth as concerns human experience. We configure purposeless mechanism (mechanism of the physical world) with our own purposes all the time. Our entire technological history not to mention art, science, and philosophy begin with that ability. If physics and intelligent agency get along as we experience them, and if our universe is everywhere basically the same, there is no reason to insist that agency characteristic of intelligence did not add information to the universe possibly starting with the big bang. Only an agency outside the universe explains everything, where all the information came from, including the universe, the settings. Physics cannot address itself to the nature of that agency because whether it is physical or not, it is not a part of our universe.
