Adventures In Quantumland by Ruth Kastner: commentary and review

Picture of me blowing smoke

Ruth Kastner has made another effort to explain the “transactional theory of quantum mechanics”. My Amazon review of this excellent book is included below with a link to her text. In this commentary I address one technical aspect (or consequence) of the theory and separately her more speculative ideas in chapters 6 and 7 (both mentioned in the review). Her first attempt at explaining her ideas to a lay readership, the book “Understanding our Unseen Reality” 2015 is reviewed here.

The technical issue is I hope straight forward. In Dr. Kastner’s scheme, energy is not transferred, nor a spacetime event realized until a virtual or “incipient transaction” becomes a “real transaction”. Incipient transactions happen between any potential emitter of some quantum of energy, and all the possible absorbers of that quantum (the atoms that could absorb it) throughout the universe! They happen outside of spacetime and so their instantaneous virtual interaction throughout the universe is not at issue here.

What is at issue is that as I read her, no real transaction can begin until one of the emitter (offer wave) absorber (confirmation wave) pairs is promoted to a real transaction. A photon cannot be emitted until it has a determinate absorber destination! How does this idea work if the absorber is an atom in the detector of a telescope on Earth, and the emitter is a star in a galaxy 10 billion light years distant? How could there have been an actualized transaction between a star and a telescope that did not exist when the photon was emitted? I have identified two separate problems here.

First, the confirmation waves come from absorbers capable of absorbing the photon which, at the time of its emission, might have been an X-ray photon. But by the time of its real absorption by some atom in our telescope detector has been stretched way into the red end of the spectrum. It is possible that our red-capable absorbing atom could not possibly have produced a confirmation wave for an X-ray photon.

Secondly, at the time of the emission, the atom that ended up in the detector of the telescope might have been anywhere in the vicinity of the Earth/Sun system such as it was at the time, perhaps a just coalescing mass of hydrogen gas and dust swirling around a proto-star. How did that lucky atom end up in our telescope and not in the center of the Earth, or the moon or anywhere else in the solar system? Further the spatial relation between the proto solar system and our emitting star would be completely different than it is now 10 billion years later. But when we trace the path of our captured photon it always appears to have made a beeline (least time) path between the emitting star and that particular place in space where the Earth (and our telescope) just happen to be 10 billion years after emission.

I suspect Dr. Kastner has an answer here, or I am misunderstanding something about what she means about emission requiring an actualization between offer and confirmation waves. I hope she will address a query sent to her. If she does I will update this blog entry with her explanation.

In her chapters 6 and 7 she goes off the rails speculatively speaking. Her aim in chapter 6 is free will. There is nothing here that hasn’t been said before by others (broadly a theory called dual-aspect monism, see my “Fantasy Physics and the Genesis of Mind”). Kastner begins by demolishing the anti-free-will arguments of David Dawkins and others of a similar type. She does a marvelous job from the viewpoint of the idea’s epistemological absurdity. If there is no free will, then Dawkins’ book isn’t really “his” and so on. In this she is entirely right even to pointing out that the view reduces us to automatons, something I have said for years (see my “Arguing with Automatons”).

Kastner points out that if nothing else, quantum mechanics shows the universe is not fully deterministic. Quantum mechanics “makes room” for free will. That’s fair enough. She also recognizes that “making room” and “the phenomenon” (free will) itself are two different things. Why? Because free will is not merely not-determined (indeterminate) but purposeful. Free will introduces teleology and if not for the universe as a whole then at least for the free-willed individual. Choice is always exercised “for a purpose”, and this is something quantum mechanics doesn’t address unless…

Kastner’s next move, the metaphysical move, is where she goes wrong. Perhaps, she says, quantum phenomena are not merely indeterminate. Perhaps they are also proto-volitional; there is in the phenomenon that which leads directly to the human sort of free will through some ascending volitional hierarchy? Something is “built into physics” that bears the germ of volition. She is, in effect, saying: we have a mystery here (free will) and we have a mystery there (Quantumland), perhaps one mystery is the explanation of the other? Now she emphasizes that this move is pure speculation but what is the point of it other than to fix a source of volition in a universe that is otherwise determinate and indeterminate at the same time, but not volitional.

No one (including Dr. Kastner) asserts that virtual quanta are conscious, but nor can anyone (including Dr. Kastner) tell us in what exactly, besides the non-teleological behavior described so well by mathematics, this proto-volitional consists! What is even a single “identity characteristic” of a proto-volition? In what way does (or even might) proto-volition contribute to quantum measurement outcomes? Where would a proto-volitional term fit into the equations of quantum mechanics? If there is no place for it why say it (volition) might be there other than the purely metaphysical need to have it start somewhere coupled with the metaphysical assumption that there is nothing more to the universe than the physical (including Quantumland).

To put the matter another way, Quantumland is speculation but not “empty speculation”. There are observables, particles communicating at seeming space-like distances and being in two places at once. A “foundation to macrophysics” outside of spacetime makes perfect sense in this context. Raw space and time can be seen to emerge from its seething processes. Quantumland explains a lot. It gives us part of the mechanism of spacetime emergence, and it removes the mystery from many of its emerging observables.

By contrast there is no observable that demands volition at the microscopic level. That volition (or proto-volition) is to be located there explains nothing about the mechanism of [much later] emerging consciousness. Free will is expressed only by or through consciousness (human or animal) as far as we know. The speculation here is empty of content. Nothing stands as an example of a property that ultimately adds up to consciousness or the volitional will of consciousness.

Quantum mysteries are encountered at just the point where they enter spacetime, but volition is not encountered in any obvious way until we reach all the way up to macroscopic brains. This is not to say that quantum phenomena are not involved in producing consciousness. It would surprise me if they weren’t! But this does not mean that quantum phenomena are themselves volitional or even proto-volitional there remains no teleology in physics.

This then brings me to chapter 7 where there is a related problem. The problem in chapter 6 is the emptiness of the speculation, the ad hoc quality of throwing volition into Quantumland because materialism has no other place to put it. In chapter 7 the problem is an induction fallacy. That Eastern metaphysics refers to a world beneath (or above or beyond) that of our physical senses, a world that is the source of the physical, does not mean they are talking about Quantumland! A Buddhist or Hindu using the word ‘energy’ and a physicist using the same word are not necessarily talking about the same thing (Dr. Jacob Needleman pointed this out to me a long time ago using “The Tao of Physics” [Capra], one of the books Kastner mentions in this chapter). Of course they could be talking about the same thing, and if you read enough of both you can cherry pick qualities from each that seem to overlap. Kastner does this in this chapter.

At the same time, Dr. Kastner gives herself the clue to their difference. The “spiritual traditions” all ascribe some sacredness to that which underlies our ordinary reality, but she doesn’t fully grasp the implications. Sacredness is intrinsically teleological. The source of our ordinary reality according to the “spiritual traditions” is purposeful, and being indirect products of it, we human beings have some relation, some responsibility to that purpose. But in no wise does it make sense to say we have any responsibility to Quantumland (nor does Dr. Kastner say such a thing), and this is precisely because Quantumland is not teleological.

Kastner must realize this implicitly as she reminds us multiple times that her ascription of volition to Quantumland (chapter 6) has no bearing on her physical theory as such. But nor is the traditional ascription of sacredness to “the other” some sort of mistake on the part of such traditions. It is a necessary quality of the other to which the traditions refer; a demonstration (as it were) that they are not speaking of Quantumland! There is nothing wrong with calling attention to the fact that spiritual traditions refer to “another reality” underlying our ordinary experience. Quantumland is also another possible reality underlying the macrophysical. But they are two different kinds of “other reality”.

If materialists wish to insist that the sacred sort of other doesn’t really exist, I can only say that until such time as there are observables that pick one theory out over another the same can be said of all the competing quantum others advocated by physicists and philosophers today.

I will leave things here because after all neither of these chapters bears in any way on the transaction interpretation of quantum mechanics as a physical theory. Unlike in her addenda to this latest book, Dr. Kastner isn’t resolving any paradoxes in these chapters. Indeed the misapplied logic (chapters 6 & 7) and misunderstood metaphor (chapter 7) is all on her side; though again and to repeat, none of this has ought to do with the explanatory value of the physical theory.

Adventures in Quantumland: Exploring Our Unseen Reality. Ruth Kastner 2019.

In (2015) Ruth Kastner, a physicist and philosopher, published “Understanding Our Unseen Reality”, a layman’s version of her earlier “The Transactional Interpretation of Quantum Mechanics” (2014). This book, “Exploring Our Unseen Reality”, is something of an addendum to that earlier work. It is really two books in one. The first half (roughly) is the book, while the last half is a collection of papers authored by Kastner, and sometimes collaborators, each addressing a specific (usually in more technical terms) issue covered in the book’s first half. Kastner frequently refers back (by chapter and page) to her earlier book. It isn’t necessary to have read the earlier book, Kastner makes her overall case perfectly well in this book alone using minimally more technical language (really symbols) to which she introduces us. On the one hand, this book’s explication of the theory’s main points and implications is brief. On the other hand, Dr. Kastner has had a lot of practice explaining the transactional interpretation and this latest attempt is clear and succinctly expressed.

Beginning with the basics Kastner moves us through subjects that are important to understanding her with a particular emphasis on the fact that her theory does not demand (I get the impression she encounters this idea a lot) that some mind be present to “collapse the quantum wave function”. To be clear, there are wave functions that minds do collapse. the ones that end in a quanta-absorbing event in one of our sensory neurons (and from there up the chain to our brains). In general, however, wave collapse is the result, the completion, of a measurement and that means a transaction between a quantum emitter and some absorber whether that absorber is in an eye, a brain, or the detector of some instrument.

The key to the theory is that the transfer of a quantum (measurable energy) requires an interaction between an emitter and absorber. There are two sorts of interactions here, incipient and actual. Incipient interactions happen between an emitter (an “offer wave”) and every potential absorber in the universe (“confirmation waves”), literally every atom that can absorb a photon of that particular energy. It doesn’t matter if these potential absorbers are near to or far from the potential emitter (in the incipient stage nothing has been yet emitted). Every incipient potential occurs instantly and simultaneously throughout the universe. One of these “offer wave/confirmation wave” (confirming that some emitter is ready to emit) “incipient transactions” wins out (remember this has taken place in zero time and across all space from our viewpoint in timespace) and becomes an “actual transaction”. The photon is emitted generating the beginning of a real singular timespace event propagating at the speed of light, and ends when the winning absorber receives the photon. The absorption constitutes a measurement because energy is transferred between the emitting and absorbing atoms. The transaction is complete.

If Dr. Kastner is right here, her theory has implications as revolutionary as the original insight (energy is quantized) resulting in the first generation of quantum mechanics. It would mean that no real photon can leave an emitter until a real absorber is selected out of the incipient possibilities. Personally I do not see how this can be. What if the absorber, the one that completes the transaction, is at the business end of a telescope while the [real not incipient] absorbed photon was emitted from a star 10 billion light years away; long before that telescope existed? There are several potential issues here and I suspect Kastner has an answer, but she does not explicitly address this. See my blog for further discussion.

In the final chapters of the book Kastner gets speculative about quantum mechanics and mind or more specifically the possibility of free will. This is not the “mind collapses the wave function” business, but its opposite. Not only does quantum mechanics give us an escape from absolute macroscopic determinism (fair enough) but rather that the quantum realm is somehow proto-volitional. The last chapter explores some speculations on the potential analogy between Kastner’s Quantumland (beneath spacetime) and various ideas present in ancient Greek and Eastern (Hindu and Buddhist) metaphysics. Kastner follows others, citing references, in all of these speculations. I have huge problems with both of these ideas, but this is not for a review and Kastner is sedulous about these ideas being purely speculative, having no direct bearing on the transactional theory as such.

Following her last chapter, Kastner gives us an epilogue calling attention to (and thanking) her predecessors in the explanatory thread leading to the transactional interpretation, followed by an addendum in which she addresses several long standing “quantum paradoxes”. Her aim here is to show that they are not paradoxes at all, but bad interpretations of data even apart from the transactional theory, and that the transaction idea can make paradox resolution easier to grasp.

In summary an excellent if abbreviated explication of the “transaction theory”. In response to her previous book I said that Dr. Kastner’s theory is the only one I’ve ever encountered that “explains quantum mysteries without explaining them away”. Having read this book I see no reason to change my mind.

Review: Terence Horgan “Austere Realism”

As I noted at the top of my Amazon review (see inclusion below), Hogan’s “Austere Realism” and Graham Harman’s “Object Oriented Ontology” are, near as I can tell, exact inverses of one another. Harman’s view is that everything is real, everything is an object. Every star, planet, building, book, nation, thought, and all their relations, a virtual infinity of relations between everything and everything else taken individually and in sum. “All objects”. Horgan’s view it the exact inverse. For Horgan there is only one ontologically genuine concrete object in the universe, that being the universe taken as a whole, across all time, what he calls “the blobject”.

Both theories, in their own way, amount to saying the same thing. Whether “all is one” or “literally everything is an object”, both declare that “everything is the same”. On a strictly ontological level, there is no distinction to be made anywhere. This is not to say that the two theories say the same thing, not at all. But because they are both at the extreme ends of the metaphysical spectrum they both collapse all distinction and end up explaining nothing.

Horgan doesn’t mention Harman; not in the book nor the copious end notes. None of Harman’s books are even listed in the bibliography. I am surprised. Although the polar opposite of Horgan’s ontology, I would think the common feature of “being at the extremes” of ontological speculation would be worth a mention. I have dealt with Harman in several book reviews and essays here on the blog. Now it is Horgan’s turn.

In my review I do point out that Horgan’s book has two purposes; to set forth his “blobjectivism” and to show how, even if there is but one concrete particular in the universe (the universe itself) this idea is perfectly consistent with talk about a multiplicity of objects. “The United states dollar is the primary reserve currency on Earth” is true even though “the United States”, dollars, currency, and “the Earth” do not strictly exist. The same is true for more purely physical assertions. “Mars is the fourth planetary orbit outward from the sun” is true though there is no Mars, planets, orbits, or the sun. These statements can be true because their truth lies in semantic contexts that only “indirectly correspond” to some as yet unspecified phenomena of the “mind-independent world”, something both Horgan and Harman must accept as real or they wouldn’t be “realists” at all.

It is the social construction of language and so the presence of varying semantic contexts that make such statements true. They are true not because the things they purportedly reference (planets, money) exist, but because they meet the semantic standards of speech concerning posits about distinctions that exist only in a mind-dependent way. This connection between ordinary speech and ontology is a nice touch, but what is it about these “pseudo object posits” that makes them unreal ontologically speaking? Horgan points to vagueness (which he also calls boundarylessness) and the “Special Composition Question” introduced by a short detour through the work of Peter Van Inwagen. Much of this Horgan illustrates with what philosophers call “sorites problems” the most famous of which (and perhaps because of this Horgan doesn’t use it) is the “ship of Theseus”.

Theseus has a ship made from wooden planks. At some point one of the planks rots and must be replaced with a new piece of wood. Is it still the same ship? What if two planks are replaced, or ten, or all of them? Somewhere along the process some people would say that it is no longer the same ship though others would disagree. But the point is there is no definite point where the replacement of just one more plank makes a different ship. This observation suggests that the ship of Theseus (and most everything else) is vague and it is an axiom of Horgan’s ontology that “vague objects” do not actually exist as such. There is no such object as “the ship of Theseus” even though Theseus (who also does not exist) is plainly sailing in something.

The “special composition question” is related to this but has to do with what is and is not a proper part of a larger construct. Does a chair (some chairs) have parts? Does it have legs, a back, a seat, and perhaps arms? The chair is subject to sorites issues; if I remove a leg and replace it with another is it the same chair? But also we notice that legs, arms, seats, and backs, not to mention chairs, are all made of atoms. Perhaps the only real parts of anything are the atoms. A chair (Van Inwagen’s famous example) is nothing but “atoms arranged chair-wise”. It has no other proper parts because they are all merely atoms arranged leg-wise, seat-wise and so on.

So what does Horgan say is the chair in the mind-independent world? He says it doesn’t exist. It is not a “proper part” of the universe. Instead, what he believes, is that the blobject, the whole universe just is in some particular spatiotemporal location arranged chair-wise. Instead of a composition from atoms on up, the key insight for Horgan is that the differentiation goes from the top down. The mind-independent “whole universe” happens to be differentiated into everything that we take to be mind-independent about the world and according to Horgan (he is explicit here) this differentiation is both real and precise; not vague.

Yet, since the blobject is differentiated into something or other not-vague (chair shaped, rocks in orbits, suns, gas clouds, radiation) literally everywhere, and all of these differentiations have effects (gravitationally or otherwise) on other differentiations around them, how is saying what Horgan says any different from saying that all of the differentiations, taken mind-independently, are simply real objects with a genuine compositional structure? If the blobject’s everywhere differentiations are not vague, where comes from that vagueness he uses to insist that suns, rocks, gas clouds, and chairs don’t really exist? If the blobject differentiates precisely and the differentiations are mind-independent, the vagueness can only come from what is not mind-independent, namely the machinations of mind both pre-linguistic and linguistic!

The problem comes fully around to bite Horgan when he speculates on mind itself. If there is mind in the universe, the blobject also is differentiated spatiotemporally into minds! Mind itself, our phenomenology taken as a whole (Horgan suggests) is also a differentiation of the blobject and for that reason precise, though the contents of any given mind, for example propositions, can still be vague. But even with this little escape for vagueness’ sake, Horgan seems committed to mind-independent mind!

This result does not appear to have given Horgan any pause, but I think it is enough to show that there are difficulties with his view he does not address in the book. In the end philosophy is always trivially right when it takes positions at the extremes of ontology or epistemology. One cannot in the end refute a pure idealism, nihilism, solipsism, or a realism that says, one way or another, that “everything is the same”. In the end Horgan is not wrong. Nor is Harman. But Blobjectivism, like Object Oriented Ontology, is a difference that makes no difference! As concerns the “mind-independent world” saying everything, including all properties, are localizations of the blobject is the same as saying that all the localizations are real and exist. As goes ontology, Horgan (though not Harman) need not worry about baldness, nations, money, or even language since none of these phenomena are strictly mind-independent.

Austere Realism: Contextual Semantics Meets Minimal Ontology. Terence Horgan 2008

Interestingly this book is a counter point and the ultimate theory is exactly the inverse of Graham Harman’s “Object Oriented Ontology” (see my reviews of various Harman books). Ironically, the universality of their views cause both philosophers the same problem. If what exists is univocal (everything is an object [Harman] or there is only one object [Horgan]) you explain everything while explaining nothing. However delving into such philosophical matters is not the purview of a book review and I will talk more about this in my blog. Meanwhile, one of my criticisms of Harman is that he never really tells us why or how he came to his position, a complaint I cannot level at Horgan as that telling is the very purpose of this book.

Horgan first introduces us to realism in general and then austere realism. He spends roughly one third of the book (at the beginning and again at the end) characterizing austere realism and in particular his version of it, something he calls “blobjectivism”. Roughly two thirds of the book he spends not on his ontological theory as such but on how that theory relates to statements in ordinary and scientific discourse. If we want to say that planets, stars, buildings, and nations do not exist, how is the scientific statement “Earth occupies the third orbit outward from the sun” or the economic observation “the U.S. dollar is the world’s primary reserve currency” true? He says such statements are true not because the “objects” they purportedly name exist, but because talk of these categories only “indirectly corresponds” to the mind-independent world. The indirection goes through the process of conceptualization.

Much of the book is an exposition of this process works; how it is that many statements in ordinary and scientific discourse can be true even though the objects they purportedly talk about do not really exist. His direct argument for their non-existence has to do with vagueness, what he also calls the boundarylessness of discursive subjects, and the related “special composition question”. In stipulating a mind-independent world he also stipulates that no mind-independent object can be vague or boundary-less. Vagueness can always be made to look inconsistent. He gets into this issue by introducing what philosophers call “sorites problems” (take a man with 5000 hairs on his head. If I take away 1 hair is it still the same man? And this is only the beginning of a sorites problem). Anything we might call “an object” within the universe is subject to this sort of breakdown. Horgan insists that this being so, none of these postulated things exist in the mind-independent world. Objects of the mind-independent world cannot be intrinsically vague.

Horgan slides between mind-independence that cannot be vague, and discourse following general and not-fully-specifiable linguistic standards (themselves vague), to what he calls the vagueness of linguistic posits about the world. The problem here, the problem Horgan doesn’t seem to see, is that all the vagueness is mind-dependent. There isn’t any vagueness about the man with 5000 hairs in the mind-independent world. The vagueness enters only when mind directs itself at analyzing the concept of that man. Horgan is quite correct I think in that all that is mind-dependent is vague. I believe this is necessarily so, though Horgan does not (and says so). Nevertheless these indirectly corresponding posits cannot be real though propositions about them can still be true. Besides introducing us to the blobject, the point of the book is the [mind-dependent] connection between Horgan’s ontology and the correctness of ordinary talk thanks to semantic context and indirect correspondence.

To my mind, Horgan fails to appreciate some of the implications of his ontology. For him, the stuff of the mind-independent world are not parts of something greater but rather spacetime localisations, differences, of “the one concrete particular that exists”, the blobject. If this is the case, and he says this, these spatiotemporal localisations must be precise, not vague! There are many issues arising here I will leave for another venue (see my blog), but the bottom line is that if they are not vague we might as well call them objects! It isn’t that Horgan is wrong (let’s say). It isn’t that ontology cannot be as austere as he claims. But it doesn’t matter. Giving an inch here is worth a mile. If spatiotemporal variations in the blobject are real and precise then conceptualizing those variations as objects, saying “they exist” and “directly correspond” (in Horgan’s semantic scheme) to mind-independent particulars amounts to saying the same thing.

Still all in all Horgan does a great job putting this together. I gave the book four stars not because of philosophical issues but because Horgan’s writing is not as clear as it might be. There are many long sentences with multiple and parenthetical clauses. Sometimes his argument is a little difficult to follow. But what was worse, the Kindle version of this book (the version I have) has a serious problem! This is not the author’s fault. The publisher was way too casual with this conversion. There are a lot of end notes in this book. A considerable amount of detail in the author’s exposition is in the end notes! But while the notes are flagged in the text, flags are not made into links. You cannot press on an end note and go to the note as as is conventionally the case in most of the Kindle books in this and other non-fiction genera. Such features are, after all, part of the point of e-books! This is a serious omission in a scholarly work like this, and makes the whole, if you really want to see the end notes as they come up, way more difficult than it should be.

Book Review: Self Knowledge for Humans by Quassim Cassam

selfie

A philosopher needs both breath and depth in the discipline. There are a certain range of issues in which I have a primary interest reflected in all of the essays on this blog. But a philosopher cannot rely only on the writings of others in their field. To understand the implications of even narrow issues, one must read both opposing voices and something of other issues that may be but peripherally related. For me this is one of those books.

Is self-knowledge of the substantial variety on which Cassam focuses important to me as a person? Yes to some extent it is, and in fact the author covers that “to some extent” very well in his last chapter. Is self-knowledge important to me as a philosopher? Is it important to my specific interests? In my case crucially yes, but it is not a sort of self-knowledge, a knowledge of beliefs and why I have them (I do know what I believe and why I believe), wants, emotions, and character traits addressed in this book.

What I need better to understand is the quality of my evidence and whether it is evidence for what I believe. My primary interests often impinge on philosophy of mind (not our belief that other people or animals have minds, but rather what mind is, what makes mind happen in brains, and how this relates to physics, biology, etc) and much of what I believe is derived from a phenomenal examination of my own mind. I want to know if what I discover in that examination is genuinely evidence for what I believe.

This is a question that Dr. Cassam misses. I make no criticism of his work here. It is clear from his exposition that the metaphysics of mind is not his subject. Who or what is this entity that believes, wants, feels, and has character traits? None of what Cassam writes here hinges on any particular metaphysical view of this entity. Yet surely an answer to this question is about one’s self? It is about what one believes constitutes the self. My interest is in what I might learn of the self as compared to knowledge about myself. While not addressing that question, this book provides a helpful context. Thanks to  my reading, I am better positioned to describe that entity and what I can (perhaps) infer of it in the context of self-knowledge more broadly conceived.

Self-Knowledge for Humans by Quassim Cassam (2014)

As with many other philosophy texts I’ve reviewed over the years this one is both professional and well written. There is almost a formula for doing good philosophy in the analytic tradition. Begin by clearly stating the nature of the problem you are going to address. Briefly review the history of the issue; make distinctions, show that the problem is more than trivial. Here the subject is something of a narrow subset of philosophy of mind, epistemology, phenomenology, and even psychology. It is the nature of what, how, and why we know, or fail to know, about ourselves as this pertains to our beliefs, emotions, desires, characters and more. Cassam sketches distinctions between the trivial and the substantial in self knowledge, and also the occasional (what I’m thinking, believing, feeling, wanting, right now) versus the standing (what do I believe, fear, want, and so on over time).

Next address the various theories about the subject in the literature and show why they are inadequate, if not entirely then at least partly. This review often, and in this case does, take up much of the book. Third make a positive argument for your own theory, in this case what Cassam calls “inferentialism”; describe it carefully and show how it addresses the inadequacies of the other dominant theories in the subject area. Then address specific objections to your theory advanced by others and show why they do not have the force their authors believe they do.

Cassam does all of this masterfully and manages not to be dry in the doing of it. He ends with two chapters on related matters, one being self-ignorance itself distinguished into variations and brought under his theory, and lastly a chapter on a meta-issue, why these inferences, why self-knowledge is or might be important.

Is Inferentialism convincing? Well yes, given how much Cassam emphasizes its broad but not always universal applicability. His claim is that Inferentialism covers much of the ground because it can be conscious or unconscious (sometimes this last is better understood as “interpretation”) and would often, but not always, be the dominant means by which we come to know things about ourselves. In short there are a lot of distinctions to be made about what self-knowledge is, and Inferrentialism happens to address all of them (including self-ignorance) to a greater or lesser extent, but is never, or almost never, absent entirely from the process of coming to know things about ourselves. Objections to the idea are unable to gain purchase because Cassam fully accepts that other theories have explanatory power here and there about this or that sort of self-knowledge, but points out that none of these, even if they happen to be operational in specific cases, preclude an inferential component to the path to self-knowledge. It is about as neat and tidy a package as I have seen.

“Self-Knowledge for Humans” would make a superb introduction to the style of Western Analytic Philosophy. In addition it well illuminates the issue and makes a substantial contribution to our grasp of what a solution looks like.

Book Review: I am a Strange Loop by D. Hofstadter

This book deserves a lot of additional commentary, but I will keep it short and begin with philosophy of mind’s “elephant in the room”; free will.

Hofstadter rejects free will. No such thing, any appearance to the contrary an illusion. But even worse, it is an illusion on top of an illusion (the agent whose will it is) on top of another illusion, mind, that is subjective consciousness, also illusion or at best epiphenomenal with zero power of downward causation. Of course. What else can he say? He is committed to all of this being nothing more than manifestations of physical process in the brain whose complexity in some unspecified way becomes self-referencing, creating some sort of physical effect (like a harmonic oscillation though he doesn’t say this) that magically transforms itself into our subjectivity. A harmonic oscillation (a complex pendulum) that becomes an unmeasurable (by third parties) interiority.

Despite this multi-layered trickery, Hofstadter uses the word ‘soul’ many dozens of times throughout the book, even calling human beings “spiritual animals” in his conclusion. To what, in this epiphenomenal context, can these concepts possibly refer? Nothing. They are meaningless terms standing for illusory abstractions. Surely he knows that these words, in a non-physicalist context, stand for something purportedly both real (not illusory) and yet non-physical. To be sure, even in their normal context they are vague terms and there is no end of debate among philosophers of religion about what they reference. But all agree they reference something not material. But God is a fantasy to Hofstadter. Words normally associated with “God talk” can be appropriated and made to mean anything one wants. Nothing about ‘soul’ or ‘spirit’ can be real. Although the words are real enough in the English language, they literally can mean nothing what-so-ever as  that to which Hofstadter applies them is ultimately an illusion.

Take beauty, the simplest of the values (truth, beauty, goodness) to grasp because we detect its manifestation in the physical world. Physical things (whether natural or artifactual phenomena, sunsets or art) strike us as beautiful or not but either way the perception of beauty is something that exists only in mind. We seem to see it in the material world, but there is not much controversey about its status as a purely mental phenomenon, coming out, in what would have to be Hofstadter’s view if he is being consistent, as an illusion in an epiphenomena. While having no causal power, our epiphenomenal mind can itself have an illusion about which we might report: “that is a beautiful sunset”. But this is but another behavior determined by the purely physical operation of our brains, a report that happens, magically to coincide with the illusion arising in a causally impotent epiphenomena having no correspondence what-so-ever to any physical quality of the sunset.

This leaves all of what Hofstadter says he values, the memories of a wife he loved deeply, and the children he continues to adore, his close friends, his career, all illusion. Memories are an imperfect mental record of past experience, but experience is nothing but effervescent epiphenomena. They don’t mean anything because meaning is intelligible only to a subject, itself an illusion. He likes to think he acts out of love for his children, but this is impossible unless there is downward causation. Love has an experience that is overtly more than its physiological concomitants. This part of it is quintessentially mental, and therefore epiphenomenal. There is nothing there that has any stake (and in any case cannot be a cause) in the behavioral game.  Like beauty, physics does not find love in the causal mechanisms of the physical world.

If Hofstadter is right, then we might as well be zombies of the sort envisioned by his student (years ago) David Chalmers. Our interiority would seem to belie that. Chalmer’s “philosophical zombies” (P-zombies) have no interiority, but then our having one makes not the slightest difference to anything we might say or do, like “I love my children”. There is no “him” (all illusion) there to love anything, only his brain that determines the verbal report made.

Hofstadter declares to us that he “takes mind seriously”. Another zombie-report forced on him by his brain, just as that same brain forced him to pen that book. This is not “taking mind seriously”. If you take mind seriously, then you have to come out a bit like John Searle (whose critique of “machine consciousness” Hofstadter swipes at here and there throughout the book). Searle takes mind seriously. He says that he cannot shake the feeling that nothing about the entire history of human experience, not to mention the day-to-day experience of individual humans, makes any sense, becomes unintelligible, unless free will, and even personal agency (for Searle at least of a functional and not ontologically real sort) are both real. Searle, being ultimately a physicalist, admits he cannot figure out how this would be possible, but he nevertheless cannot shake the conviction that it is. Hofstadter (Searle and many others also) has another option, one that his  sort of “taking it seriously” prevents him from considering. He could take consciousness, agency, and free will to be real, and conclude that therefore physicalism must be false!

If one takes mind, and provisionally like Searle, free will and agency seriously, if physicalism is false, then one moves on to asking what must be the case about reality as a totality that makes these phenomena possible? What must be true about the universe if these subjective experiences are experiences of real phenomena? This is a question that Hofstadter, like Searle, cannot bring himself to ask.

I Am a Strange Loop by Douglas Hofstadter 2004

Douglas Hofstadter, justifiably famous for “Godel, Escher, Bach” wrote about the much trickier subject of mind and personal identity in this 2004 book. It is one thing to analyze the relation between three applications (their results in Math, visual art, and music) of self-referencing thought, and quite another to analyze the entity doing the thinking. Hofstadter begins with Godel because as it will turn out, his insight into the recursive descriptiveness of number theory from which self-reference was (supposedly) banned by Bertran Russel, becomes his inroad into a philosophy of mind. Hofstadter is a master at describing (without mathematical formalism) what Godel did and why it matters. He is not so good at applying this to mind.

Besides Godel, the author’s other insight comes from the loopy-like nature of recursive entities like infinite halls of mirrors or what happens when you point a television camera at the screen displaying what that camera is viewing. We all have seen these, and from these two things, Hofstadter assembles a theory of mind based on the idea that whatever goes on in the brain at the low and mid physical levels results in some sort of abstractions (perhaps manifested in harmonic oscillations of electromagnetic energy) that from another perspective, are the very stuff of consciousness.

There is nothing particularly new about this. Rejecting religion or other basis for any sort of dualism (and his remarks are rather disparaging in this respect) and declaring oneself a physicalist (there is nothing more than physics) is par for the course and occasionally swatting straw-man arguments to the contrary, is all part of the contemporary game for most of today’s philosophers and scientists. Besides religion he mentions David Chalmers who was, apparently, a student of Hofstadter’s in his doctoral days and rejects Chalmer’s non-religious panpsychism (and along with this presumably Davidson’s “dual aspect” monism as well) which is fine as far as it goes.

Hofstadter’s theory is somatic. Mind arises from what goes on physically in the brain and nothing more. The problem is he never gets to connect up the subjective with anything that can, even in theory, be measured by third parties. This is not to criticize him alone here, no other physicalists (or for that matter panpsychists) manage to do it either, but in this case the author jumps from the neurological layer to the concept of self-referencing abstraction (presupposing consciousness) without pointing to anything in between that might connect the two.

After declaring his theory “explained”, Hofstadter moves on to considerations of how one strange loop-abstraction, the one that fools me into the illusion of a stable “I”, is influenced and modified by others. He is much impressed by Derek Parfit’s thought experiments [supposedly] demonstrating that what we take to be the uncopyable core of ourselves, is nothing but effervescent illusion and can in fact be copied. Moreover, though we cannot copy it today (and may never be able to do that in reality) we can, from our own interiority, find ourselves being partial expressions of other people, their strange loops!

He supposes that our own personal-identities form slowly as we proceed from infant to child based on all the various influences that impinge on us from the world as these come to influence new effects in our own minds. The totality of all this over time results in a relatively stable, but not changeless, personal identity. He moves on from there to suppose that those we hold and know particularly closely (our parents, wives, children, siblings, etc) can cause their own identities to be partly duplicated in our own minds. None of this really makes sense. Of course someone with whom we are close for many years will have a proportionally larger influence over the shape of our phenomenal arena. What he doesn’t seem to appreciate is that this influence takes the same pathways (our interpretation of sensory experience for example) as the initial early development of our own personality. There isn’t any loop in my brain that is a copy (however imperfect) of my wife or children’s identity, only modifications of my own that represent them.

There is much here and I do not doubt that writing “I am a Strange Loop” was a labor of love in more ways than one. It is, as with other somatic theories, even possible that oscillating fields in the brain have a lot to do with consciousness and personal identity. There are still reasons to believe that this is not the whole story.

The Mistake in Theological Fatalism

“God knows everything you’ve done and loves you. God knows everything you are going to do and still loves you” Vern Benom Grimsley

There is a present fashion among intellectuals, a belief they are not free willed in the libertarian sense, that libertarian free will is impossible in a universe of randomness (quantum mechanics) and determinism (everything else). Although this present fashion is rationalized by modern physics, the idea is as old as the Greeks. Democritus (of atom fame) was one of those who believed this, and so the debate has gone on for some 2400 years.

I make no secret of my scorn for this fashion (see “Arguing with Automatons” and “The Nonsensical Notion of Compatibilism”). It is the philosophical equivalent of adolescent obsession with self-mutilation. Philosophers, even atheist philosophers like John Searle (“MIND” 2005 and “Making the Social World” 2010), Nicholas Rescher (“Free Will: A Philosophical Reappraisal” 2009), and Edward Lowe (“Personal Agency” 2006), address the absurdity of this position, though Searle admits he cannot reconcile his epistemological conviction that free will must be genuine with his equally strong metaphysical conviction (grounded in physics) that it is impossible.

In this context, the term ‘libertarian’ is not a political ideology but refers to the idea that some agency, my “I”, is volitional; “at liberty” to cause (in Rescher’s term “initiate” [atemporal cause]) some sorts of neurological activity in my brain. Some entity (often called mind) is the starting point of actions instantiated in the physical world by my body. In effect a subjective agent, I, and not merely neurological activity (which I am not aware of directly) am in command/control of my body, and this I, while resting on neuro-physiology, has some independence from physics; there is a gap between that which chooses, and the physiology the choice precipitates. For this reason, the term “contra-causal will” is associated with libertarianism.

The idea here is that this “I” in command (mind?) does not appear to be a physical entity and so libertarian free will commits to the added idea there is in the universe a “cause of the physical” that is not physical. This idea violates a central principle of physics known as the Causal Closure Principle (see “Fantasy Physics and the Genisis of Mind”). The two ideas, libertarian will and contra-causal will, are therefore associated, but the connection rests on the assumption the “I” is not a physical object. ‘Libertarian’ refers to phenomenology, first person experience, while ‘contra-causal’ cause is a metaphysical idea. “Theological Fatalism” addresses the former and is not necessarily committed to the latter should the “I” happen to be physical (see “I Am a Strange Loop” 2004 by Douglas Hofstadter and Lowe referenced above).

THE PROBLEM

On the other side of the debate, philosophers of religion (also going back to the Greeks) have an escape. God, being omnipotent, knows the trick of making contra-causal (and so libertarian) free will possible in a universe whose only other causes are random or deterministic.

Logicians then framed a puzzle. If God is omniscient, he knows everything that has, is, and will happen. This has to include every choice ever made (and ever to be made) by any minded being, personal or otherwise. If that is the case, if God already knows that when you step into a taquiria you will today order pollo and tomorrow carne asada, how can those choices be free? You cannot avoid the problem by intending to order chicken and then at the last moment changing your mind; God knows you will do that too. This puzzle is called “Theological Fatalism”. Even if God is the source of a third (contra-causal) cause, and “mind causes physics” (Sean Carroll “The Big Picture” 2016, something Carroll of course denies is possible) that cause cannot be free in the libertarian sense because God already knows what the choice will be and can never be wrong about it.

The puzzle is reminiscent of Zeno’s paradox (back to the Greeks again). Zeno said that movement, change in space, is impossible because to move a mile, or a foot, or even a millimeter, one has to go first half the distance, and then half that distance and so on blocking any movement before it begins. Although it seems obvious that we can move, it took some time for philosophers, early mathematicians, to figure out where Zeno goes wrong. The distance between any two points can be divided into an infinite series of smaller distances. Mathematicians demonstrated that one can traverse or complete an infinite series in a finite time. Zeno did not account for time and in a sense the same is true of Theological Fatalism, or at least that is a part of the story.

Before I dismantle this puzzle I want to note that this argument is raised by scientists and philosophers by way of ridicule; God himself is (or would be) inconsistent with free will. Oddly, many present-day theologians and philosophers of religion have accepted the argument and decided that therefore God is either not omniscient or not omnipotent!

If a theologian does not understand that God must be able to do and experience in ways we cannot and that there are logical riddles, transparent to God, we cannot (perhaps never will) fathom, who will? Such philosophers should hang up their philosophy hats and go away. Logically probing how such qualities as omnipotence and omniscience go together and yet provide for free will is one thing. Denying this is possible because they cannot figure out how it works is ridiculous; the pinnacle of hubris!

THE SOLUTION

If God is God then he knows everything that has, is, and will happen throughout time with absolute assurance, never guessing, and never being surprised. His knowledge is immediate and atemporal, it is a knowledge of a sort we know nothing about by experience, nor can we grasp it logically. We can suppose that God’s knowledge must be infinite and perfect, but not what that is like to experience it.

I’ll go further for the sake of the conundrum. Harry Frankfurt is famous in ethics circles for coming up with a puzzle. A mad genius has learned to take over brains and can cause a person to make any decision the genius wishes. Moreover, the genius knows (here is the real genius) what decision you make as you are making it. If your decision is what the genius wants you to do anyway, she need do nothing. But if your decision is about to be what she doesn’t want, she can force you to make the one she wants and do so in such a way that you do not even realize you are being forced! The question is: is your will still free?

The short answer to the Frankfurt question is, I think, yes you are free when you make the decision the genius wants and no otherwise. My point in bringing this up is to note that God has the power (omnipotence plus omniscience) to be the supreme Frankfurt genius! While we appear to be free, we are merely compelled (having no feeling of being compelled) to follow God’s script. But this mistakenly implies a causal relation between what God knows and what we do. No one claims theological fatalism precludes freedom because it is causal . It is rather a logical problem. God does not cause, that is force, us to make a particular choice.  The matter is rather about what God knows in what seems, from our viewpoint to be “ahead of time”. But God’s foreknowledge is foreknowledge only from a human, temporal, perspective. What ever be the limits of human libertarian freedom, even the most dyed-in-the-wool libertarian does not suppose that such limits include contravention of natural law, including time.

In the comments here an interlocutor points out that what God knows amounts to fate, and for this reason we are not free. It is a viewpoint that amounts to a deduction from a universal perspective impossible for us to actually have. Since “God is one” one might argue that everything that, to us, appears differentiated about the universe is all illusion or but a shadow of the singular unified reality. This ignores the manifest, to us, reality of matter and a richly differentiated universe. Both views reflect the same singular reality, some shadow to God, differentiated reality to us. It is from this perspective that we are free even if what we choose is, from God’s universal view fated.

No libertarian claims our freedom is absolute. Just as we cannot contravene natural law, so also we cannot surprise God. So long as (and assuming) mind is a cause in time, the future is genuinely open in time! If from our perspective, always limited to the present, a choice makes a future difference, then our choice is free from within that perspective.

Of course we might still be wrong about this if God is a deceiver, if it is in fact the case (as in Frankfurt’s clever puzzle) that we are not the cause of our choices, or that we are that cause only when we choose what God has foreordained. But if we are deceived then God has to be causing our choices and that is not the crux of theological fatalism.

There is every reason to believe that God (should he exist) cannot be a deceiver (see Prolegomena to a Future Theology). It does seem to experience that our will itself, the subjective mind exercising it, is (provided we are of normal brain) sovereign over choice no matter what choice we make. That God knows what that choice will be does not abrogate its freedom from within the view of our temporally constrained, to the present, perspective.

From our viewpoint, future possibilities from among which we choose (God knows these also) are in fact genuinely open to us because we do not know what God knows. We do, subjectively, choose from among alternatives and “which choice” we make makes a future difference to us and others whom the choice may entangle. This is all a robust libertarian free will needs. The strongest advocates of libertarian will do not demand that no power in the universe knows what you will decide.  Being unable to “surprise God” does not equate to fate from our perspective.

Libertarianism requires only that we cannot know what that power knows and as concerns God’s viewpoint this is surely true.  To say then: “well our freedom is purely perspectival, or stems merely from our limited perspective” is trivially true, but over-simplified. All freedom short of God stems from or exists within some perspective. It is freedom nevertheless because from within any perspective it bears causal responsibility for the particular choice made.

All that libertarianism requires is that subjective agency, the self-aware subject, and not deterministic neurophysiology nor God causally, initiates action from within its perspective and this requirement is fully satisfied in the human experience of willing. We are free in our experience and if “mind can cause physics”, if contra-causal cause is real (possible if God is real), and God is not a deceiver, then we are free in the libertarian sense, from within our perspective, despite what God knows. God knows what we will choose, but so long as his knowledge is not a cause of our choice our will is free within its constrained perspective. Theological fatalism is a false doctrine.

Fantasy Physics and the Genesis of Mind

selfie

Physics rests on the “causal closure principle” (CCP). The CCP has three legs:

CCP(1): Physics comes only from physics.
CCP(2): Physics produces only physics.

Together these say the physical effects we observe come only from prior physics, and physical causes (using cause in its common language sense) produce only physical effects.

CCP(3): There is no teleology in physical mechanism, no goal-directedness. CCP(3) is something of a corrollary of the first two legs. Physical relations and interactions are either determinate or indeterminate, but either way they are not “before the fact” directed at particular outcomes.

If God does not exist, the only philosophy of mind (PoM) consistent with all three legs of the CCP is eliminative materialism. Every other nontheistic PoM that rejects eliminative materialism and accepts that mind cannot be logically reduced to physics, violates the CCP in one or more ways.

PoM theories that claim mind exists in some sense of that word, that mind is real and emerges from ordinary physics without anything “in principle undetectable” (QM aside) added to physics to make it happen violate CCP(2) but not CCP(3).  They assert, plainly enough, that physics results in something that is in some sense non-physical, but mind’s emergence is just as accidental (contingent) as all other [physical] emergent phenomena (from stars to liquid water to life).

PoMs claiming that physics is incomplete, that something else must be added to ordinary (measurable) physics to make mind emerge (dual-aspect monism and panpsychism of various sorts) violate both CCP(2) and CCP(3).

Only theism can both accept all the CCP while accommodating mind’s reality (and for that matter libertarian free will). Theism also grounds our conviction of agency which nontheistic theories universally deride. I write about theism extensively but my purpose in this essay is to show that the [supposed] problems with theism for physics and PoM are no worse than those of nontheistic PoMs. This is to say both suffer from equally serious metaphysical and epistemological problems.

Being inaccessible to empirical (or for that matter logical) demonstration (or falsification), a “God hypothesis” is a speculative solution, a curve drawn arbitrarily to fit points (mechanistic nature of the universe joined with free will for example). Other speculative solutions, so it is claimed, are equally possible and equally impossible to confirm or deny. In fact however it is more difficult than it seems to come up with these alternative solutions. Speculative solutions that fit all the points (the mind-independent world and everything in experience) and remain logically coherent are difficult to invent. Many have tried. Like theism, atheistic attempts at solving the mind problem are also data-free speculative solutions because the data, mind emerging from brains, cannot be observed!

Physicists are often eliminative materialists (nothing emerges strictly speaking) or reductive-materialists (only an epiphenomenon emerges).  Only eliminative materialism is fully compliant with the CCP and logically coherent, but it is also the solution that is most prima fascia absurd from the subjective viewpoint it denies exists! Reductive-materialism either violates CCP(2) if epiphenomenal-mind is taken to be something real or it is logically incoherent! Physics causes the external conditions of a mirage, but the illusion that is the mirage happens only in a mind. An illusion presumes a subjective experience in which the illusion occurs.

The view that a non-material mind emerges from ordinary physics violates CCP(2)! The idea is coherent because mind is not taken to be an illusion. The problem is that no physicist has ever seen a physical phenomenon emerging into (or as) a nonphysical one. We see physics emerging from physics all over the universe from galaxies and stars to liquid water to life, but all of what comes of these events (causes and effects) is physical! The retort from physics is that we do not see any other non-physical emergence because the one such thing that has happened in the universe is the very mind we are trying to explain. Mind is the evidence that physics can produce mind. Surely this argument is circular? It plainly begs the question to say that the evidence physics alone can explain the appearance of mind is mind!

There are a few philosophers who follow the physicists here (John Searle, Bob Dole among others), but many philosophers see problems in this approach. First there is the circularity already mentioned, but in addition, this solution (whether it includes a role for quantum mechanics commonly sited by both physicists and philosophers) entails that mind’s appearance is contingent. Not only might it not have appeared in the universe, something every materialist accepts, but its appearance is mysterious. The mystery applies to mind in general, and individual minds in particular. Why is consciousness ubiquitous in animals with complex nervous systems?

Troubled by these problems, materialist philosophers seek solutions that remain [purportedly] physical while, at the same time, channeling universe evolution towards consciousness and by doing so taking its mystery away. But every one of these solutions violates CCP(2) and CCP(3)! The idea that universe evolution is directed is plainly teleological! This is what prompts philosophers (and some physicists) to grasp the straw of quantum mechanics,  but this (I will argue) doesn’t help them.

To explain genuine mind in a Godless universe there are dual-aspect monisms (Henry Stapp, Donald Davidson, Thomas Nagel) and panpsychisms (David Chalmers, Philip Goff, John Leslie). Under normal circumstances both of these theories would count as metaphysical, that is not physical theories at all! They are physical not logically, but merely by ancestry. Purportedly they remain physical (or physics grounded) because their novel (never specified) qualities can only have originated in the big bang!

Dual-aspect monisms make the claim that physics is incomplete in the sense that there are additional fundamental properties in micro-physics not yet (and perhaps never to be) discovered. The physical in this view includes the mental in a proto-property form. This undiscovered addition is not conscious; atoms are not aware. Nevertheless the qualities of this extra-physics direct event unfolding towards that which yields consciousness. Working backwards from consciousness, this channeling must also encompass the preconscious stages of life’s evolution and the origin life throughout the universe. To our empirical experience, only life, some life, becomes conscious, and that only as it gains the right sort of complexity following millions of years of evolution.

If dual-aspect monism of any sort was true however, we would expect its effect to show up in the equations describing the regularity of physical evolution. There is no such term in the equations of macro physics so to say that this extra aspect of the physical is a part of physics surely begs the question.

This is why I think so many philosophers grasp at quantum dynamics to locate proto-mental qualities. We cannot directly measure quantum phenomena until they interact with the macro physical world, and quantum phenomena, technically, are not random but indetermined. Perhaps (so they speculate) we can locate the proto-mental in the difference between ‘random’ and ‘indeterminate’, in effect shielding teleology from possible detection? But surely a proto-mental is not the only possibility accounting for the restriction from random to indeterminate (see note on this distinction at end of essay).

Furthermore no one (physicist or philosopher) has been able to say what properties the proto-mental has, how they restrict random to indeterminate, or how the indeterminateness of the quantum phenomena we know push the macro universe towards consciousness. Even Henry Stapp’s “Quantum Zeno Effect” addresses only the narrow interface between brain and the human type of consciousness. Even if this speculative connection turns out to be a measurable phenomenon, no one has suggested how the physical world accommodates it. They all seem to agree that the proto-mental cannot be conscious in the sense that we experience it, but that tells us nothing of what properties it does, or even might, have and how they work!

What all of these theories entail however is that the mental (the proto-mental at least) must be antecedent to the physical! If it has a downward influence on the physical, which these views entail, it has to be ontologically real! Where does it come from? If the foundation of the universe is physical, what is it in or of the physical that grounds the proto-mental? The idea of a proto-mental here is not incoherent by any means. But it’s coherence largely depends on there being something about the fundamental ontology of the universe that isn’t physical! Moreover something that directs with intention!  Teleology is here introduced something the more honest of the philosophers admit they cannot seem to avoid.

For these reasons, dual-aspect monisms violate CCP(2) but they also violate CCP(3) because whatever else the extra might be it is clearly teleological. Instead of the universe ending in one state or another driven only by contingent process, the extra-physics channels evolution toward a specific outcome! It is therefore purposeful in the sense of being goal-directed.

Panpsychism is the converse of dual-aspect monism. It isn’t that mind builds up particle by particle thanks to some undiscovered property of particle physics, but rather it is the universe taken as a whole that comes to embody the extra physical qualities. Philip Goff (in a paper) neatly distinguishes two forms of panpsychism, micro and cosmo versions. Micropanpsychism is much like dual-aspect monism. The mental is attached to physics at the particle level but it isn’t effective except as contributor to a totalizing affect of the cosmos. Micropanpsychism has dual-aspect monism as a foundation but asserts that its impact is felt only in relation to the whole universe. You might think of this like neurons and brains. Every neuron in your brain is a foundation of brain functionality. But mind doesn’t show itself other than at the level of the whole brain, or at least large parts of it. In Micropanpsychism, the properties of the whole emerge from properties of the parts.

Cosmopanpychism abandons the dual-aspect foundation and asserts it is only the universe as a whole that reveals proto-mental properties. This view needs no micro-alteration to physics. Mind emerges from brains the way stars emerge from gas clouds because special properties of the totality, properties described by laws parallel to those of physics, are able to invoke it. Somehow, the entire universe acquires properties (usually not taken to be conscious as such) that come to direct physical evolution, and then biological evolution, towards consciousness.

This idea clearly violates CCP(3) (it is teleological) but is precisely an attempt to avoid violating CCP(2).  It is unsuccessful because the panpsychist claim is essentially that from the total state of the universe there emerges a parallel collection of qualities (properties and laws) that evoke mind from brains!  At one level or another, physics results in non-physics and so violates CCP(2). Besides Goff, David Chalmers is a proponent of this view.

For the cosmopanpsychists the “mental qualities” do not (typically) amount to the emergence of a literal Cosmic Mind, a “thinking universe”. Such a view would amount to substance dualism at the level of biological mind! But the philosophers who assert this do not, with one exception that I know of, specify what any of these properties are. As is the case with all the other theories, none of the qualities that supposedly effect the transformation nor any part of the mechanics of their interaction with the other-than-mental are anywhere given.

The exception here is John Leslie who asserts the property or quality characterizing this emergence is goodness. We normally think of goodness as a quality of the character of persons and so, by extension, of their minds. Emerging with the big bang is not only purposeless physical mechanism, but a parallel quality of goodness. A universe pushed in that direction is so pushed because goodness is a quality of it from the beginning, and mind is good!

To get the job done, any of these extras must, necessarily, be effective. It does no good to say that something besides the physics we know, something that is nevertheless physical (or quasi-physical), might or might not push cosmological evolution towards life and life towards consciousness. If the operation of these extras is itself contingent then what would be their point? To do the job they must not only have the necessary power, but that power must result in their goal-directed effect. The extra-in-physics, its goal-directedness, must be logically antecedent to the physics we measure that does not, in any aspect, appear goal-directed.

Where does antecedence come from? Since all of these philosophers are materialists, it must originate, with everything else, in the big bang. But there is nothing in the physics of the big bang that contains anything of the mental, anything of this extra there, and certainly nothing to which we can point that bears value; goodness. The big bang is a quintessentially physical event. What is  the proto-mental property in physics? How does it arise from within an other-than-mental physics and yet be logically antecedent to physics?

The extra-in-physics, under any of these approaches, hangs, metaphysically, on literally nothing! In John Leslie’s view, not only is universal mechanism goal directed, it is also moral! For him, morality happens to pop into the universe with the big bang and it is this quality that underlies drift towards the mental. How, presumably in the absence of any mind, has this direction become good? Even if it is, how does goodness effect the direction of physical contingency?

Does physics itself have an analogous problem with this last point? Where does the physical universe come from? Why is there any physics at all? Physicists have an out. They have the quantum vacuum which, while purportedly physical, cannot in principle be directly probed. This boundary layer between physics and nothing insulates physics. As concerns physics itself, and anything it gleans of quantum phenomena, the CCP is not violated. It is for this reason, I think, that so many philosophers reach for the quantum straw. We have already seen that this move is ad hoc. Moreover it goes against that which we have discovered about quantum behavior. No “mental term” is needed in the equations of quantum mechanics any more than in macrophysical equations, and goal-directedness is not implied by any of our multiple quantum interpretations.

To be fair, many of the philosophers who propose the solutions outlined above recognize that these suggestions violate the CCP. All claim (often citing Occam’s Razor) that violating the CCP is less onerous than supposing there is, for example, a God who knows the trick of making all of this work out the way it has. Working out a way, that is, for purposeless physical mechanism, mind, and even libertarian free will, to coexist in the universe. What troubles me about these philosophers is their refusal to admit that these problems (what brings about cosmological mental properties. How precisely do they interact with physics) are in some respects more mysterious than God! At least God can be supposed to “know the trick”.

Perhaps in the greatest twist of irony,  many of these minds have thrown up their hands and returned to idealism, abandoning the CCP entirely! Not only is the mental logically antecedent to physics, it is ontologically prior! The above mysteries are resolved because mind causes physics and not the other way around! The irony is that, in essence, this is what theism has claimed all along! I should not need to point out that in God’s absence, the metaphysical ground, prior to physics, of the mental is unfathomably mysterious!

How does a “God hypothesis” avoid violating CCP(1) with particular regard to free will? Doesn’t a genuinely (libertarian) free will entail (as Sean Carroll has put it in “The Big Picture”) that “mind causes physics”? In a narrow sense yes, theism violates CCP(1) but theism has an out. Mind is presupposed after all and constitutes the one exception to CCP(1) in the universe! The Theist is free to change CCP(1) to read: “physics comes only from physics and mind”. This move doesn’t help the physicalist because for her, the issue is the emergence of mind from physics without presupposing mind. They can, of course, say that mind is the only exception to CCP(1), but that surely begs the question, there not being any other evidence that physics can do this.

The change to CCP(1) is not circular in Theism. Yes mind is an exception. It is in truth a cause of physics. But here mind is presupposed. CCP(1) is not violated because mind doesn’t emerge only from physics. The exception, that part that evokes subjective experience from brain activity, comes not from physics but by some indirect route from God. It must be indirect (I do not believe God personally manages emerging individual minds) because God is changeless while mind, individual mind, changes with time. Mind’s direct source (besides brains) must be inside time.

Theism does not violate CCP(2) because physical mechanism still produces only physics. The result of mind-producing-physics, say the movement of my arm, remains physical. Theism does not violate CCP(3) because physical mechanism remains perfectly purposeless. Purpose as such remains entirely in mind. Notice that CCP(3) does not say that the physical universe has no purpose, only that the local operation of its mechanism (macro and micro)  is purposeless.

The goal of this essay has been to argue that nontheistic notions of mind’s emergence (or lack of existence) have problems equal to or exceeding the problematic aspects of theism. Let’s review.

God is a fantastical being. Positing his existence demands at the least an addition to what physicists take to be the only ontology of the universe; the physical. A God hypothesis demands that this entity has the power and knows the trick to producing the physical as well as causing minds to arise from the physical work of brains and interact downward with the material world. This mystery cries out for a physical explanation; at least a suggestion of what it is about the physical that makes that connection. Theism does not supply this physical answer, but nor does physicalism or any of the extra-physical theories covered above.

On first blush, the extra-physical ideas demand less addition to our fundamental ontology. The physicalist theories demand, if not technically an addition to ontology, at least that the physical can do that which no observation, no experiment, has seen it do; bring about something nonphysical. The extra-physical theories do demand a new, non-material addition to ontology. It isn’t God, but yet it must have the power to bring life and then mind about. Not only must it have this power, it must surely succeed. If the emergence of consciousness remained contingent and might not have happened the extra-physical qualities of the universe would be redundant. Further, any direction, anything other than absolute contingency, implies a teleology that has to be antecedent to the physics it influences!

The atheist philosophers who hold such theories recognize that they do move partway towards God (at least a Deistic version of him). In effect they are a “functional God”. But if there is no real God, then in what, metaphysically speaking, do any of these properties cohere? If you add to this stand-in the property of “having purpose”, and to backstop an infinite chain of prior cause, being first (and so uncaused) cause, you pretty much have gone all the way to God. In the end, the purely physicalist theories are nonsensical because mind is both prima facia obvious and non-physical. The extra-physical theories, if they do not need all the qualities of an “Abrahamic God”, require enough of these properties (non-materiality, purpose, antecedent cause) to be equally fantastical! When, in addition, you accommodate the problem of these mysterious properties emerging, literally from nothing, you end at a full-blown God concept that is at least deistic if not fully theistic.

Note on the distinction between ‘random’ and ‘indeterminate’

The distinction is important in quantum mechanics (I believe) because quantum phenomena come out in a well known and repeatable probability distribution even though there is no reason, no cause that we know of, why they should not be actually random. An electron could, theoretically be anywhere in the universe but there is a 99.9% probability that it will be found in bounded range of locations.

Here is a mundane macrophysical example I hope captures the idea. Imagine a fair six-sided die. Any face from 1 to 6 can come up with equal probability. The die is random within the confines of possibility (even an electron cannot be outside the universe). Now suppose you have a heavily-loaded die in which two sides, 1 or 6 are likely (and repeatedly) to come up on 90% of the throws, but within that 90% a 1 or a 6 are equally likely. That die is no longer random, but it is indeterminate.

 

Review: The Order of Time by Carlo Rovelli

By sheer coincidence I published the essay, “What is Time”, shortly before reading Carlo Rovelli’s book. Rather than writing additional commentary here, I put a pointer to that essay. While it does not address Rovelli directly (I hadn’t read him yet) it covers the points made in the review included below. But I do not want to discourage people from reading this excellent book. It is always good to understand the arguments of authors with which you (in this case I) happen to disagree. One cannot claim to be a well rounded philosopher without understanding what it is that those you disagree with are saying.

The Order of Time by Carlo Rovelli (2018) Amazon review

Like consciousness, time is a subject that no philosopher or physicist has ever managed to nail down completely. Thanks to their slippery character, being so close to us (the first one IS us) they are endless sources for fountains of speculation. In this book, Rovelli’s subject is time, but consciousness comes into this narrative as well.

Rovelli is a “time denier”. OK, that’s being a little unfair but not by much. What he denies is that there exists an independent, fundamental property or quality of the universe that is time. Of course the universe is full of movement and change, events unfolding into other events. His basic position is that time emerges into our perspective, our viewpoint, from these phenomena, but it is merely an illusion. The movement is real, the changing is real, but the time in which all of this seems to occur is nothing more than a manifestation of human (possibly animal) mind and the illusion, in turn, is supported by the entropy generated in the functioning of our brains.

The book (not long read) is divided into three parts. In the first Rovelli covers the various sub-disciplines of physics and their temporal implications (or lack thereof). He begins with classical physics (the equations work backwards in time), and moves on to General and Special Relativity, and quantum mechanics. Here he demonstrates that our simple intuition of a universal time flowing from past to future is untenable. Time, mind-independent time, if it exists at all, cannot be like that. In part two he further demolishes time. Not only is it not what we think, in and for physics, it doesn’t really exist at all; even the present is an illusion! In part three, he puts time back together for and in the perspective of an subjective viewpoint.

He argues it is the fact that we view the world from a perspective, that when we perceive the world we inevitably blur the details into a sort of summary or gestalt for our perspective, that causes time to appear to mind, The physics supporting that appearance comes down to thermodynamics. Human time, brain time, is “thermal time”. Certainly Rovelli thinks thermodynamics (in particular the 2nd law) is real, but while responsible for what consciousness perceives of time and so a real enough subjective experience, from the 3rd party perspective of physics, change is real, but time is a mirage.

This book is written for a lay audience. There is almost no math in it (what there is appears in footnotes), and it defends a view common to much of the physics and philosophy community. To be sure Rovelli differs a bit from some of his peers. He argues that relativistic “block time” is no more a “true portrait of objective time” than any other theory. In Rovelli’s view remember there is no such thing as “objective time”.

In 2015 a philosopher (Roberto Unger) and a physicist (Lee Smolin) wrote “The Singular Universe and the Reality of Time”. This book (reviewed by me on Amazon) makes precisely the opposite case from that of Rovelli. Of course they recognize what Relativity and quantum mechanics imply about time, but they maintain, nevertheless, that a notion (and reality) of objective, “universal time”, is more fundamental than any other phenomena of the universe, even more than space! Rovelli mentions this book in a footnote and admits that Unger and Smolin’s view “is defensible”, but he leaves it there and never addresses what is defensible about it.

The Unger/Smolin book goes against the grain of 95% of today’s physicists. Personally I agree with Smolin and Unger. The fact (thanks to limiting effect of the speed of light) that we cannot map our present to any present in a remote galaxy, or even the nearest star does not mean there is no present there, in fact everywhere. Something is happening, NOW, everywhere in the universe. We do not know what it is, but that does not mean the present isn’t real as Rovelli believes. Had Rovelli directly addressed Unger and Smolin I would have given this book another star. Had he not mentioned them at all, I would have taken another away.

In summary this is a decent and well written book advocating for a particular view of time (or no time) that I happen to think is wrong, but what do I know? It happens to be the dominant view in physics today. Rovelli is a well respected physicist and a good writer. Those of you interested in the subject will find this book valuable whether you agree with the author or not.
