Book Review: The Universe in a Single Atom

Picture of me blowing smoke

We’ve all heard of or noticed it… The solar system: a sun and planets, mostly empty space. The atom: a nucleus and electrons, mostly empty space. As above, so below! The analogies are in-exact, but they still serve to illustrate that the stuff of the universe is mostly empty. That part is true unless you count fields. Fields aren’t made of atoms but they do pervade empty space. In this book there isn’t much discussion of fields, though they are mentioned. Mostly the book is about consciousness, but I’m going to focus on the metaphysics of Buddhism as the Dalai Lama summarizes it because as must be the case it grounds the Buddhist view of consciousness, identity, and has implications for the matter of free will.

It all begins with that emptiness. It is worth quoting some key passages here because they hold in their language the key to their truth and error.

“At its [the theory of emptiness] heart is the deep recognition that there is a fundamental disparity between the way we perceive the world, including our own existence in it, and the way things actually are. In our day-to-day experience, we tend to relate to the world and to ourselves as if these entities possess self-enclosed, definable, discrete, and enduring reality. … The philosophy of emptiness reveals that this is not only a fundamental error, but also the basis for attachment, clinging, and the development of our numerous prejudices.”

“All things and events, whether material, mental, or even abstract concepts like time, are devoid of objective, independent existence. To possess such independent, intrinsic existence would imply that things and events are somehow complete unto themselves and are therefore entirely self-contained. This would mean that nothing has the capacity to interact with and exert influence on other phenomena.”

“Effectively, the notion of intrinsic, independent existence is incompatible with causation. … Things and events are ’empty’ in that they do not possess any immutable essence, intrinsic reality, or absolute ‘being’ that affords independence.”

“In our naive or commonsense view of the world, we relate to things and events as if they possess and enduring intrinsic reality. We tend to believe that the world is composed of things and events, each of which has a discrete, independent reality of its own, and it is these things with discrete identities and independence that interact with one another.”

Is his eminence correct about our ordinary, commonsense way of seeing things? I do think my automobile is a discrete particular I can positively identify in part because it endures through time. But those existence (enduring through time) and identity (my car, is a different particular from your car) criteria exist only because a mind (mine or yours) abstracts them from the concrete reality of the object. Independence here (in both the commonsense and philosophical view) implies only independence of a particular from mind. The object exists and has certain characteristics that I can name, but I do not create them. Nor, however does it imply that there endurance is any more than temporary, for a time, and that one day they will cease to exist.

Obviously automobiles can interact with the world causally. Certain of their properties, mass for example, have causal implications. If all the Dalai Lama is saying here is that no object, no event, is permanent, eternal, then this is but a trivial truth. It seems to his eminence that “independent existence” entails changelessness, not merely “mind independence”. Of course he is right that material object or event is eternal, but that does not mean it lacks all independent existence if only “for a time”. The object is not empty, even though it is temporary.

I do not agree with a lot of what Graham Harman believes, but he does handle this issue well. In summary:

1. Everything (material things, events, thoughts, intrinsic and extrinsic relations, etc) is an object.
2. Every object has both an essence and dispositional properties. The dispositional properties can be enumerated and quantified, the essential properties never entirely known.
3. Even given #2, objects and their essences are temporary. They come into existence at a time and go out at another time.
4. It is through their dispositional properties, not essences, that objects interact causally and relationally.

Harman claims to be a realist albeit from a continental background. While he need not represent here the majority opinion in modern philosophy he is comfortable with objects having an essence which does not participate in events (causally or otherwise) and at the same time dispositional properties that do. I suppose what makes this possible is temporal dependence, something the Dalai Lama denies is possible for essences. Because no eternal object exists (East and West [mostly] agree), they cannot (in the Lama’s view) therefore have essences. In the Western view (if one holds there are essences), this object, essence and all, had a beginning and will have an end. Putting this another way, the one physical phenomenon to which essences relate, or in which essences participate, is time!

Another quote is telling: “By according intrinsic properties of attractiveness, we react to certain objects and events with deluded attachment, while toward others, to which we accord intrinsic properties of unattractiveness, we react with deluded aversion.”

If there is one thing all modern western philosophy has in common it is the assumption that there is such a thing as “mind-independent reality”. The debate in Western terms is over what can be said or known about the mind-independent world, not its existence. To a realist, real objects (whose dispositional properties are discoverable by mind) exist and have all their properties, essential or otherwise, prior to and independent of their apperception by any individual mind, human or animal. Not all objects are like this of course. Thought-objects (Harman a big fan) of course do not, but even some material objects. A particular automobile, once built and prior to its someday destruction, is mind-independent now, but its origin in the past, its coming into existence as a mind-independent object, cannot have been possible without some mind’s intervention in the causal stream.

Who today, in the Western tradition, would say that attractiveness was an intrinsic property? It is in the Western sense, a relational property between some (possibly) presently-mind-independent object’s dispositional properties and some mind! One of the insights of modern science is that the mechanisms of the mind-independent universe (essences or not) are teleology-free (see “Fantasy Physics and the Genesis of Mind”)! Attractiveness, by contrast, is implicitly teleological. It is attractiveness for the purposes of some mind whether for some pleasure, survival, or merely aesthetic appreciation.

In the Dalai Lama’s view, the ground of all reality is empty of all properties. At this ground, there is no distinction to be made between mind-dependent and mind-independent reality. All are equally empty. His eminence takes this to be a fundamental truth. So when we get to what amounts to an illusion of a differentiated world he does not, other than superficially (from within the illusion) distinguish between mind-dependence and mind-independence, emptiness all!

There is yet another problem. The emptiness doctrine might be incoherent. If the fundamental ground of everything including space and time is emptiness where does all this illusory stuff come from? That is to say where does anything that can have illusions come from? Emptiness at least implies quiescence. Not only must it be free of any real, mind-independent, stuff, it is free also of any process. Nothing happens! How is it that anything comes to be at all?

How does the emptiness doctrine impact the matter of free-will? If the differentiation of everything is an illusion, then that we (an illusion) have an effective will must also be illusion. One of the great differences between Hinduism, and especially Buddhism, as compared to Judeo-Christianity and Islam is that the former religions aim at being a “vessel of the divine”. The personal goal of those religions is to realize the emptiness of all that is. The net result is quiescence, merging with emptiness as a drop of water merges with the ocean. Will, among our illusions, has nothing therefore to do. In fact doing anything, willing anything is counterproductive, and precisely what leads to desire and misery. It isn’t that God wants us to do nothing, it is that like everything else God is empty. Technically speaking there is no “divine” only the empty ground of all that is.

Western religions, by contrast are religions of action. God and the universe are not nothing. They have positive existence. The goal of these religions is to bring what God wants (ultimately for us to love one another) to fruition and this takes place only when we freely will (of our own volition) and so act (or attempt to act) to bring that state about now and in the future. If free will does not exist (not because all is empty but because only brain-states have any causal efficacy) obviously this would be impossible; impossible that is to “freely choose” to do God’s will.

If a transcendent God of a sort envisioned by Western religions exists (this is not to say the real God would in all qualities be what is said of him in Western holy books see “Prolegomena to a Future Theology” for a less conflicted portrait) not only must free will be real, it must be the linchpin of the process for getting from the present to the future God intends (see “Why Free Will?”). But why would an omnipotent transcendent God set things up this way? Why not just make the universe the way he intends it to be from the beginning? The answer can be inferred from our sensitivity to values (see “What are Truth, Beauty, and Goodness?”) free will itself. What God intends must be that universe resulting from the mass-exercise of value-sensitive minds freely electing to instantiate (literally “make instances of”) the values.

If the Dalai Lama’s metaphysics of emptiness was true, and everyone on Earth achieved union with it, human history would end; everyone would starve to death! By contrast if the transcendent God exists, and everyone freely chooses, to the best of their evolving capacities, to do his will (the collective instantiation of truth, beauty, and goodness being love) the life of every individual on the world would be paradisaical! Because we (who are not illusions in this view) are partnering with God, freely choosing his way rather than what might be our own, the universe ends up better (apparently) than what God could have done by himself because all value-discriminating wills in the universe are freely on board!

The Universe in a Single Atom by the Dalai Lama 2005

Who can critique the Dalai Lama? He is a smart, wise, man with a curiosity about pure science, and a pragmatic streak about technological applications. Should they benefit mankind, alleviate suffering, they are good. The Dalai Lama seems to have wanted to write this book thanks to a life-long fascination with science coupled with insights of his years of Buddhist training. He tells us as a boy growing up he had no training in western science whatsoever, but he was fascinated with a few (first-half 20th century) examples of western technology belonging to his predecessor. As a young man, once vested in his office, he availed himself of a new-found access to many of the world’s greatest minds, philosophers, scientists, artists, and so on. He has gone on talking and learning from great minds ever since.

After this introduction, the book looks at the physical (cosmology, quantum mechanics, relativity) and then life sciences. I was hoping he would not get into a “Buddhism discovered it first” argument, and mostly he does not. He comes close on the subject of quantum mechanics but I think mostly because at the time, the people from whom he learned it still took seriously the idea that individual human minds (for example that of a researcher) could be responsible for wave-function collapse. If this were true (the idea has long been put to rest as concerns individual minds) the tie-in with the Buddhist mind-first world-view and deep exploration of that first-person (consciousness) world would indeed be strong.

Even within quantum mechanics his eminence is sensitive to the great gulf between the western scientific paradigm and the focus of Buddhism. He well illustrates these differences while pointing out to scientists that much of what they take to be the “structure of reality” is a metaphysical assumption. It does not follow necessarily from scientific methodology which so well illuminates structure as concerns the physical world.

But this same methodology can say very little about consciousness. It is with consciousness that he spends much of the book examining the views of modern brain-science and how they might relate to Buddhist discoveries. The views of these different worlds stem as much from the purposes of their separate investigations as the technique; empirical 3rd-party evaluation versus highly-trained rigorous introspection. Becoming a master monk takes as many years as obtaining a PhD in physics (more in fact), but he mis-uses the term ’empirical’ here. What the monk does and what the monk learns in the doing should not be dismissed by western science, but it is still subjective and for that reason not empirical. He advocates for joint research. Neuro-scientists together with trained monks, he thinks, might help unlock some of the mind’s mysteries. He also is aware that not all mysteries are unlock-able!

In the book’s penultimate chapter he uses the then-new technology of genetic manipulation to plead with the scientific community to take it slow. He wants us all to be asking the right questions concerning the long term affects of the possibilities on our humanity. Here the contribution of Buddhism is the importance of compassion, of constant awareness of the mission to alleviate suffering. He is very good at identifying frightening possibilities in the technology and lists them. At the same time, aspects of the field, the need to produce more food, provided it isn’t motivated purely by financial gain, can be good. In his last chapter, his eminence returns to the same subject, a cooperation between science and Buddhism’s focus on bettering the human estate, not only physically or biologically, but socially, psychologically, and spiritually.

The book is full of interesting philosophical implications I will perhaps explore on my blog. These have more to do with physics, cosmology, and what western philosophy calls metaphysics than with consciousness which Buddhism takes more or less for granted. The idea that the stuff of the universe is fundamentally phenomenal suffuses all schools of Buddhism, while in the West the idea, while not unknown, is viewed with great suspicion. Where consciousness is concerned, his emphasis falls on intentionality, our capacity to direct our attention, but he never mentions free will. Like consciousness itself, perhaps Buddhism takes free will for granted.

What are Truth, Beauty, and Goodness?

In many essays of this blog I discuss what philosophers in prior centuries called values:  truth, beauty, and goodness, distinguishing them from facts. I have to sketch these over and over because my approach to a philosophy of mind, in particular any discussion of what distinguishes human from animal mind has to bring up the values. It is the ability to distinguish the values, that is to grasp that truth, beauty, and goodness exist and are discernible, that separates human from animal mind. This essay focuses on the values as such.

Is goodness (or beauty or truth) objective or subjective and relative? This is a question that has vexed philosophers for more than two thousand years. The answer, grounded in my theology (see “Prolegomena to a Future Theology”) is that it is both. It is the point of this essay to show why and how that is the case. What the values are falls out of my theology as does the distinction (made by almost no one in the philosophical community) between what values are and what has them. Goodness is a value. Justice (to take an example I will use below) is usually taken to “be good”. Justice is good (if indeed it is) because it has, embodies, or is an instance of goodness. This distinction holds for all three values. A sunset has beauty, and a proposition like 2+2=4 has truth. In the English language we normally say that justice is good, sunsets are beautiful, and propositions are true. It is this construction that blurs the distinction presented just above just as, pointing at a lit lamp and saying “that is light”, would blur the distinction between light and what is lit.

In the Prolegomena (linked above) I note that from a rational first-principle theism we infer there are three fundamental joints in reality: Matter-energy, mind, and spirit. Matter-energy is the familiar stuff of the material universe, including time. Mind refers not to individual human (or animal) mind, but the phenomenon of mind in the universe. To our experience of course mind manifests individually (see “From What Comes Mind?”). The reason mind so well represents the material world is that mind and the material world both originate in spirit. The point of mind is to represent matter-energy (in the human, biological case, on middle scales) to a subject. The subject is yet another matter I will not much deal with here. See “Why Personality”.

Human mind can, and animal mind cannot, sense something of antecedent spirit-reality, a thin something that is, in effect an inkling of “the character of God” or more precisely qualities of God’s character. Values, their reality, not what exhibits them, are that of which we are aware, by means of mind, is spirit. It is the only such awareness (of spirit) we have. Mind represents the material world to a creature having an individualized subjectivity. The phenomenon that catalyzes a brain’s evocation of a subjectivity is the same everywhere. The quality of spirit that humans can sense and further discriminate in their mental arena is present (everywhere) in the field I have called (again see above linked “From What Comes Mind?”) Cosmic Mind. The lion, or the dog, or the ape, simply do not notice it, do not detect it as a distinguishable facet of consciousness. Animal mind is not up to the task. Being “up to the task” is the identity criterion for human mind.

Values are the unified quality of God’s character refracted into the three primary joints: beauty into the material world, truth into mind as such, and goodness into the intentions (and intentional behavior) of persons (personality being the only spirit-component of our otherwise blended identity — see “Why Personality”). They also happen to be the root concepts of three major branches in philosophy,  aesthetics, epistemology, and ethics respectively.

Beauty is something we experience in sensory qualia and they, in turn are our window on the mind-independent material world. We find truth by mind in mind. To philosophers it is a property of propositions. Propositions are abstractions, mental phenomena, that either do or do not conform to the structure of the world as a whole, spiritual, mental, and material. There is a “fact of the matter” about the relation between General Relativity and quantum mechanics, and about the existence (or nonexistence) of God. Like beauty, truth is not about what is true or which abstractions have more truth, but rather the conviction that there is a consistent way the world is.

Goodness is about the intentions, and subsequently behaviors, of persons. Again it is not about what purposes are good, or how much goodness they have, but that it is possible to align (more or less) our individual purposes with God’s. Goodness is the most difficult value to grasp intellectually because it is the value refracted through reality’s “spirit joint”. Of matter we know much, of mind we have immediate experience, but of spirit we have only the mind-discriminated values themselves and personality which we cannot find (see “Why Personality”).

At the same time goodness is the value with which we most often engage. Persons, by extension their behavior, have (or do not have) goodness, but this is also the case with social institutions which are impersonal, but created by persons. Unlike the other values we project goodness strictly outside (though of course it remains related) its domain, the person. In doing this we invent new words for it, for example ‘justice’, fairness, or fitness. But in each case, though we speak of impersonal institutions, we refer to the doings, present or historical, of people.

There is something to note about the values taken together. As God is unified, the values, while refracted to human apprehension in reality’s three primary joints, must also be unified. Each must be consistent with the quality of the others. Beauty must be both true and beautiful, goodness beautiful and true, and truth beautiful and good. This interrelation between the values, recognized in classical treatments of them, has sometimes been identified with ‘love’ (Christian Agape) and is consistent with the view that they are what we apprehend as qualities of “God’s character”.

Our thin sense of these qualities is only a hazy pointer. It is not a reliable arbiter of what about particulars in the world (human art, propositions, or acts of persons) has these qualities or more exactly to what degree they have them. Values are apprehended in mind, but we recognize they belong to broad categories in the physical (a sunset), mental (a proposition) or personal (some exhibition of human intention) world. Subjective interaction with the world is always perspectival, it has a viewpoint. Perspective is unique to every human being who’s history, not to mention a unique physical ground (the brain) of the mental, ensures that uniqueness.

Each of our individual, already unique by different brains, perspectives color our general value awareness. There is room in the human perspectival range for both broad agreement and much disagreement about what is true, beautiful, or good. Suppose we face a palette of colors and must classify each into one of only three groups, red, yellow, and blue. We might agree about many of the various shades, but when it comes to an orange, I might say it belongs more to the red and you to the yellow. It is because of this colorization effect that we can have different views of say the value content of a sunset (or work of art), proposition, individual act or social policy; whether, for example a particular human action or policy enforced by law, is just.

There is another phenomenon that, to human mind, relativizes the values, time itself. Time, of course, is an ingredient in our own individual perspectives, but it is also a part of the social perspective we share as a culture. We are conditioned not only as individuals but also as a culture. Almost all humans agree there is often beauty in sunsets, but art is a different matter. The people of 17th century Europe expressed a wide variety of views on what makes up beauty in art. Faced with 19th century impressionistic art they might have had the capacity to extend their view of beauty-in-art to include it. But show any one of them a painting by Picasso or Pollack and few would find any beauty in them as many do today. What has happened here? The capacity of present-day individuals (some of them) to respond to beauty in a wider variety of art forms results from broadening this capacity within the evolving culture. The same holds for truth. There was “more truth” in Newton’s theory of gravity than what came before him, but still more in Einstein’s General Relativity.

For another example lets look at justice, not retributive justice but social justice. We take for granted nowadays that universal (in adults) and equal suffrage with regard to selecting political representatives is good because it is just. Justice, in other words, has goodness. But even in the Earth’s best models for the social evolution of universal suffrage (England and the United States) achieved today’s notion of what is just over several (in England’s case many) generations. At each stage of the evolution, the people who lived in those stages thought of them as just compared with prior stages. The situation in the late 18th Century and early 19th when only adult male property owners had an acknowledged political voice was “more just” than the prior condition when only aristocrats had a say, and that in turn more just than when kings alone made all the rules. Fifty or so years later when all adult males could vote there was yet more justice, more goodness (or at least we think so today), in the arrangement and so on.

Political inclusiveness was just, had goodness, in 1800, 1900, and today when all adults can vote. This is possible because cultural relativity conditioned what was just for that time. What was just in 1800 was good in the same way as it is today, yet what framed its just-ness varied from one age to the next. Philosophy’s inability to reconcile the relativity of value as we find it in the world with its seeming objectivity, the nagging suspicion that it is not, at least, purely relative stems from the philosophical failure to distinguish between what the values are and what has, embodies, or instantiates them in the world. This failure in turn results from philosophy’s rejection of God who would be the only possible source of the values as we know them (truth, beauty, goodness) that could ground their existence independently of minds which discover them.

Unlike the qualia set up by physical senses, values are found in human mind as such. No physical pathway connects an “outside source” of value to its discrimination in mind. Because of this it seems plausible to suppose (most philosophers do suppose) that we just invent the values in the sense that they spring into consciousness out of the froth of mind; they are epiphenomena! Humans all recognize them (some more than others) because human mind-froth is, after all, similar from one brain to the next. While this theory does account for different qualities-of-discrimination in different minds (brains differ), it does not account for some of their objective-like qualities.

Beauty seems to be in or of the sunset. 2+2=4 seems to be mind-independently true, while one can argue that slavery is unjust always even if there was a time when it was a compassionate alternative to murder. In our experience, mind-froth produces many mental states: epiphanies, novel idea combinations, fantasies, and so on that we do not take to be mind-independently real. The values are different in this way. Their mind-independence, unlike fantasies, is controversial. This alone suggests that something different may be going on. Cosmic Mind explains both how it is values are mind-independently real, qualities of God’s character, while present only, and differently felt (brains differ), in human mind.

While not epiphenomena, values themselves, like ideas or qualia, are not causal. Values can however, like the others, be reasons for intentions. Indeed if God exists and the physical universe, consciousness, and the interaction between the two is purposeful, the values must be a linchpin of that purpose. See “Why Free Will” for a further elaboration on this point.

Review: Philosophy of Mind by Edward Feser 2006

One would expect a book on this broad subject to leave some dangling issues. Dr. Feser’s sympathies clearly lay with Aristotelian dualism, even theism. He begins with a nuanced statement of Cartesian Substance Dualism. His aim is to explicate the logical strength of substance dualism, aware also of its primary weakness (the “interaction problem”) and then ask if the various alternatives to it, particularly those promulgated by materialist philosophers of the 20th and 21st centuries, are coherent in their own right and if so, successfully defeat dualism’s logic.

As noted in the review (reproduced below with a link to the book on Amazon) Feser spends the bulk of the book on this latter task. He demonstrates that none of the suggested alternatives actually work. Some (eliminativism of two kinds and epiphenominalism) are incoherent, while others (functionalism, behaviorism, and many others) fail to capture the substance of subjective first person experience, in effect explaining it away. Most of these critiques focus on epistemological issues, but some also run into metaphysical issues, indeed the same “interaction problem” faced by Cartesian dualism (see also “From What Comes Mind” and “Fantasy Physics and the Genesis of Mind”).

Having demolished the contenders, Feser asks if there is something else, a different sort of dualism that might work and yet not require or point to theism? His solution is Aristotelian Hylomorphic dualism. Alas, as noted in the review, here he fails but doesn’t seem to notice it. Either the form emerges from the facts of the assemblage that is the brain, or it is added intentionally from the outside. Hylomorphism either collapses into reductive (or supervenient) materialism, or it leads back to something that must stand in the place of, if not be, God. Feser leaves this matter dangling.

Other issues dangle. Feser cites many authors I’ve read, among them David Chalmers, but as I read Feser, he seems to misunderstand Chalmers’ “property dualism”, more or less equating it with epiphenomenalism,  the idea that our mental arena is merely an accidental by-product of brain function with absolutely no causal consequence. It is precisely the point of Chalmers’ property dualism that it does have causal consequence and so is not epiphenomenal but rather a radical emergence.

From the physics of brains alone emerges what amounts to a substance with novel properties, the upward property of subjective experience itself, and a downward causal power, subjective will, on that same physics. Chalmers, being bothered by the radical character of the emergent subjectivity, speculates on panpsychism or various types of monisms that might be embedded in physics and so support such an emergence (see above linked “Fantasy Physics…” essay for details). These various ideas for sources of the phenomenal in a hidden property of the physical are quasi-material in Feser’s taxonomy.

Another matter of interest to me is Feser’s characterization of substance dualism. His sketch is more nuanced than that usually given by his materialist peers but there are other possibilities that yet remain broadly Cartesian. For example, a property dualism supported by the presence of a spacetime field that is not physical but also not phenomenal (or proto-phenomenal).

The field need not be mind as such. It need have no phenomenal/proto-phenomenal properties of its own. Viewed from the material, mind is a radical emergence (upward) and has, as a result of its novel properties, also downward causal qualities. Its appearance, however, its form and nature, is the result of an interaction with this everywhere present (and yes, mysterious) field and not equally mysterious undetectable properties embedded in physics. For a detailed explication of this model see my “From What Comes Mind?”

Of course an “interaction problem” comes immediately forward. This hypothetical field is, after all non-material. But this interaction issue is the same faced by property dualism generally along with panpsychism, and Russelian or dual-aspect monism. All of these theories propose proto-phenomenal properties embedded in micro physics or the universe as a whole, but none ever say how exactly to identify the proto-phenomenal, in what exactly its properties consist. Nor do they speculate on their origin, and how they interact with the physical we know; how exactly they perform their teleological function driving the physical towards [genuinely] phenomenal expression.

Feser notes that materialist philosophers always cite “Occam’s Razor” as reason for rejecting theism and so any sort of substance dualism. He should somewhere have noted Occam’s Razor is supposed to apply to two or more theories that equally explain all the data! Theism answers two of the questions left dangling by quasi-materialisms. It explains why it is we find the phenomenal, any phenomenal proto or otherwise, only in association with brains. It has also an origin story in theistic intentionality, the phenomenon we find at the core of the recognizably phenomenal, our phenomenal, itself!

Quasi-materialisms deny intention in the proto-phenomenal leaving the transition to intention in brains hooked (metaphysically) on nothing. None of this, not the postulation of a field or the proto-phenomenal explains how exactly interaction occurs. The problem with theism isn’t merely the interaction (about which at least “God knows the trick”) equally suffered by all the non-eliminative materialisms. The problem is the postulation of an intentional source of the field supporting intentionality as we experience it. Yes this is a big pill to swallow, but without it we can say nothing about how any of this works anyway. Rejecting the possibility of theism leaves behind more mysteries than it resolves.

Surely suggesting that there is an intentional (minded) source of intentional, subjective mind begs the question. Of course it does! It remains, however, a coherent, possibility! God can not only be conceived, his necessary qualities can be specified to considerable detail (see my “Prolegomena to a Future Theology”). It isn’t clear that the proto-phenomenal can be conceived, and even if we allow its conceivability there seems to be nothing that can be said at all about any  of its qualities.

I said at the end of the book review I would say something about free will. Feser does not mention it. Free will is related to intentionality. The ability to direct our attention purposefully is the core of the matter and some (Schopenhauer) would say it, is the essence of the conscious self! “Mental causation” or in Rescher’s terms initiation is, when not subconscious, agent-directed. We experience our agency as will (and this why the ‘free’ in ‘free will’ is redundant’ see “All Will is Free”). Will’s  relation to “philosophy of mind” should be obvious. We experience our volitional agency in mind, and like qualia and intention, the nature of volitional agency is mysterious, doubly so because it is a mystery on top of a mystery!

I have said much about free will and its associated agency elsewhere in the blog. On the negative side (the absurdity of denying it) see “Arguing with Automatons”, and “The Nonsensical Notion of Compatibilism”. On the positive side, “Why Free Will”, “Why Personality”, and “The Mistake in Theological Fatalism”.

The two best books on the subject are “Free Will: A Philosophical Reappraisal” by Nicholas Rescher and E. J. Lowe’s “Personal Agency”. My own books, “Why this Universe” and “God, Causal Closure, and Free Will” both address the subject.

 

Philosophy of Mind by Edward Feser (2006)

I picked up Feser’s “Philosophy of Mind”, a book in an introductory series, for the sake of little else to read at the time, but I’m glad I did. It is, perhaps the best basic-evaluation of this subject (one of my specialty areas) I have ever read. It doesn’t merely introduce and review the subject. It makes an argument, a point about the present philosophical state-of-the art on the nature of mind, and does it very well.

Feser begins by introducing the subject and settles on representative-realism (the external world is real more or less as we experience it, but what we experience as subjects is nevertheless a representation of it) as the fundamental datum which a philosophy of mind must account. He then moves to examine the various proposals put forth by modern philosophers, some with their roots back in classical Greek times. He begins with Cartesian (substance) Dualism, a rather more sophisticated treatment than is usually accorded by modern philosophy. He shows us that substance dualism rests on more solid logical foundations than is usually acknowledged even if it smacks of being unscientific thanks to its infamous “interaction problem”.

From that point Feser looks at what has been offered as alternatives to Dualism, various materialisms (eliminative, functionalism, behaviorism, pure epiphenomenalism, causalism, reduction and supervenience) and quasi-materialisms (panpsychism, Russelian-monism, property dualism). All of this treatment constitutes the bulk of the book and as he covers each solution there emerges the best taxonomy of philosophies-of-mind I have yet seen. The modern emphasis on qualia is explored thoroughly but he argues that intentionality, even given the representational realism with which he begins, is more important, more central to mind and consciousness, than qualia.

In doing all of this Feser drives home the point that none of the alternatives is without serious metaphysical or epistemological problems. All of the quasi-materialisms, in fact, come up against the same interaction problem as substance dualism, and the others are either incoherent (two sorts of eliminativism), or simply do not get at two core problems: why do we experience anything at all and why does the subject that appears throughout all experience seem so obviously causally potent?

In the last chapter Feser asks if there is anything else that does address the core issue without having to invoke what ultimately comes down to God? His answer is Aristotle’s “Hylomorphic Dualism” (also championed by Thomas Aquinas though his variation relies directly on God). To explain consciousness, to get at its core and resolve the ever-present interaction problem, Feser says all we have to do is reject the contemporary physicalist insistence that material and efficient causes (two of Aristotle’s four leaving out formal and final cause) exhaust causality in the universe. This would be, to say the least, a big pill for 21st Century science, and most of philosophy, to swallow.

Further while Hylomorphic dualism might deal nicely with the epistemological issues Feser everywhere touches, it does no better than the quasi-materialisms concerning the metaphysical. Either the form of the human mind springs entirely from the arrangement and dynamics of physical particles, in which case we are back to reductive or supervenient materialism, or it does not. But if it does not, where does it come from? That physics cannot detect any teleology in the physical universe does not mean it isn’t there. It does mean that it has to come from somewhere other than physics and be prior to individual human minds. We are on the way back to God.

There is also a notable absence. Feser never mentions free will. A discussion might be beyond Feser’s scope in this book, but I’m surprised he did not at least note its obvious relation to intentionality. I will cover this and other implications in a blog commentary.

From What Comes Mind?

This essay is about mind in general, consciousness, the “what it is like to be…” experience. What follows applies to human and animal mind. I include a note at the end about animal mind in particular. My focus is on consciousness as such, why it exists at all and why does it have the form it has. This will not be so much about the contents of conscious phenomenal gestalt, qualia, intentionality, beliefs, memories, and so on.

Many of the essays on the blog impinge on philosophy of mind. Although the assertions, analogies, and connections to philosophy here are mine, they rest broadly on the theory of mind presented by The Urantia Book. It is after all with mind that we experience the mind-represented sensory world, assert propositions, make intentional choices, sense values, and experience our agency.

The Urantia Book’s philosophy of mind is theistic and dualistic, but not in the way of Cartesian or for that matter Thomistic dualism. It does have elements of each of these but also shares much with “property dualism” of the sort championed by David Chalmers. The purpose of this essay is to present the theory and note certain relations to philosophies of mind common among present-day philosophers. The theological basis of this theory is to be found here. I begin therefore with property dualism.

Chalmers is at base a materialist. There cannot be any super-natural power in his theory, but there is nevertheless a supra-natural effect. In his view, minds emerge from nothing above and beyond physical brains. No intentional power adds mind to brains, but the emergent mind does, nevertheless, have real powers and potentials that are nowhere present in brains simplicter antecedent to mind’s emergence. These qualities include the form of our subjective arena, its qualia and the ever present awareness of our intentional agency, our will, its power of downward causation.

This is a new type of cause in the universe perhaps best described by Nicholas Rescher in “Free Will: A Philosophical Reappraisal”. Rescher advocates for far more freedom in our intentions and acts than many other advocates of free will (see Richard Swinburne’s “Mind, Brain and Free Will” for a much narrower view). His argument for the unique quality of mental-cause is that it is timeless; he calls it initiation rather than cause, it being simultaneous with its effect. This comes out to the impossibility of ever identifying a “mental cause” independent of a brain-state correlate! There is more on Rescher’s view here.

What manifests in mind (pace Aristotle) are final and formal causes where before mind there were but material and efficient causes. We experience, directly and only in the first person, the causal efficacy of our agent-purposeful-volition. The combination qualia (emergence upward), and agent-intention (downward causation) has been called a “radical emergence” to distinguish it from the more ordinary emergence that produces, from physics, only physical if novel properties. As far as we know the only such phenomenon in the universe, the only radical emergence there has ever been, is mind (see note on emergence at end)!

Chalmers’ must ask: how can this possibly work? Cartesian dualism after all is universally challenged based on a single irresolvable issue, the matter of how a non-material substantive entity interacts with a material brain. Property dualism faces the identical problem. How exactly does physics, without a built in phenomenalism, produce a non-material phenomenalism, and how then does that turn around and become a literal cause, effectively directing (however minimally) the physics of the brain? Chalmers’ answer, and the answer, in variations, of many contemporary philosophers of mind, is that physics is not without built-in phenomenalism (or proto-phenomenalism).

Both panpsychism and various sorts of monisms posit the existence in (the monisms) or the emergence of phenomenal (or proto-phenomenal) qualities from physics (cosmology for panpsychism) alone. These qualities are forever undetectable by physics but are, nevertheless, built-in to physics! There spring immediately to mind two further questions: where exactly, or how, do these phenomenal/proto-phenomenal qualities inhere in physics, and what precisely is phenomenal about them?

To the first question, none has any answer. They could, of course, say “God put it there” but the whole point of the exercise is to find a solution without postulating a minded being having such powers. But if we rule out a minded source we are left at best with a supposedly mindless source of mind. We have done nothing but push the interaction issue to another part of the rug.

The second question is equally vexing. No one wants to say that the fundamental constituents of matter (atoms, quarks, the quantum field, the monists) or the universe taken as a whole (panpsychists) are conscious or minded. The claim is that the phenomenal builds itself up as the basic building blocks (atoms or galaxies) themselves are built up. But they nevertheless insist there is something inherent in these entities that is the real root of the consciousness we have. The problem is that when asked in what do hypothetical proto-phenomenal qualities consist, none can say, or even speculate. It seems that, short of mind as we know it, we cannot say in what the proto-phenomenal consists.

How does my view help? It does not explain the interaction mechanism. It does account for the reason the mechanism cannot be explained by mind of our type. It does, however, account for why we cannot give any account of that in which the proto-phenomenal might consist. We cannot give such an account because there need not be any proto-phenomenal qualities for which to account.

Starting with the property dualism, brains produce subjective-conscious-minds in a way analogous to a radio producing music (compression waves in air that we interpret as music or speech or whatever, but this detail has no bearing on the analogy). Destroy the radio or alter its function and the music disappears or becomes distorted. This is exactly what happens to mind when brain function is altered away from normal working limits; from distortions of consciousness to mind’s destruction. Real minds do not survive the destruction of brains any more than music survives destruction of the radio. From a common sense point of view, it is perhaps legitimate to view the radio as the real and perhaps sole source of the music.

But the radio does not produce music ex nihilo. Rather it interprets information present in a spacetime field in the radio’s vicinity. The radio is the “source of the music” in that it alone is responsible for the conversion, interpretation, or translation of information present in the field from its electromagnetic form ultimately to compression waves in air, an entirely different phenomenon! One way to look at it is to say brains are responsible for the conversion or interpretation of some spacetime pervading field into the form of our consciousness. More accurately, we should say that the field has the power to evoke consciousness from the doings of brains.

The field need not, by itself, have any phenomenal qualities at all. It need not itself be conscious or minded in any sense of those terms any more than the electromagnetic wave is music. Electromagnetic information isn’t music until the radio makes it so, and the field isn’t phenomenal until the brain makes it so, or at least this is all we need to specify about it. The field is a constant throughout (as far as we know) the universe. Radical emergence is effected from the brain-field combination.

The field I have elsewhere called “Cosmic Mind” (see “Fantasy Physics and the Genesis of Mind”). Perhaps this a poor terminological choice as I do not mean to imply the field is conscious or even phenomenal in some uncharacterizeable sense. It mght be proto-phenomenal, phenomenal, or even conscious, but none of these matter to the model. As far as human beings and human consciousness is concerned the only property the field has to have is a capacity to evoke our subjective experience from our brain-states. If it has other properties, or indeed even purposes, we have no way of knowing.

Mind, in other words, springs from brains as Chalmers envisions it, and this is why it is properly a property dualism. Viewed from the material, it is a radical emergence (upward) and has, because of its novel properties, also downward casual qualities. Mind’s appearance, however, its form and nature, is the result of an interaction. The emergence of subjective consciousness from brains is enabled by Cosmic Mind. Consciousness is the music produced by brains in the (everywhere) presence of Cosmic Mind.

Unlike an electromagnetic field Cosmic Mind is not physical and that quality explains mind’s non-material quality. Cosmic Mind’s postulation accounts for mind’s relation to brains (mind’s physical root) and its subjective first-person-only phenomenology (mind’s non-material root). Qualia would appear to come from te brain side, our representation, via the senses, of the physical world. Intentionality is related to purpose, to final cause, something that doesn’t exist in physics. This quality must somehow be contributed by Cosmic Mind. How does Cosmic Mind interact with the physical? Aren’t I faced with the same “interaction problem”, perhaps pushed around a bit, as old fashioned Cartesian dualism?

The short answer is yes. It is the same problem, the same also faced by property dualism and panpsychism, and also Russelian, and any dual-aspect monism. The presence of Cosmic Mind is (like Cartesian mind) normally associated, directly or indirectly, with God, but one could leave its final source in abeyance as phenomenal monists and panpsychists do with their protophenomenal properties. None of these other theories ever say what exactly the phenomenal or proto-phenomenal qualities are let alone from where they come. Unlike the quasi-materialistic theories, Cosmic Mind is not (or need not be) phenomenal or proto-phenomenal (let alone conscious) at all. The emergent effect, subjective phenomenalism, only occurs when brains appear — Cosmic Mind being always on the scene. Unlike quasi-materialisms, this explains why we find the phenomenal only in association with brains and why we cannot even speculate about the protophenomenal in physics. It isn’t there to be found.

What about my other promise? Why is explanation of the interaction mechanism forever out of our reach? To support the radical emergence taking place, the field cannot, itself, be material (like the electromagnetic) or we would be back to unsupported radical emergence. Since it isn’t material it remains forever outside the capacity of physics (having only material instruments) to detect. Moreover, since the emergent dualism effected by the brain is also non-material the mechanism producing it is a mix of the physical (brain states) and non-physical (Cosmic Mind). Physics (in this case a synechode for neurophysiology resting on biology resting on chemistry and so on) can only measure the material side and it does! We can measure and find (roughly) consciousness-correlated brain states! What we cannot measure is the evocation subjective experience from their functioning.

What physics wants is an equivalence relation. But proving equivalence relations (for example the equivalence between thermodynamics and statistical mechanics) needs experimental confirmation, physical measurement, of the phenomenon from both ends as it were. This is precisely what is not possible concerning mind.

Where does Cosmic Mind itself come from? I’m a theist for this reason and many others. God covers a few problems. The origin of course, but also the interaction. We can never spell out the mechanism but God knows the trick! Theism has no particular burden here. Panpsychists and monists do not tell us from where come their postulated “phenomenal properties-of-physics”, or for that matter even in what they consist. The latter question I have answered!

If we let materialist philosophers get away with “we don’t know, they’re just there” why shouldn’t theists? A non-material field pervading spacetime is no less conceivable than undetectable phenomenal properties in physics. One of Chalmers’ suggestions is “psychic laws” in parallel with physical law. Postulating Cosmic Mind answers more questions than proto-phenomenal physics or psychic laws, specifically why we cannot specify, or even speculate about, what qualities the proto-phenomenal has.

Note: On emergence

I have allowed in this essay that mind is the only example of radical emergence of which we know, but I believe there are two others, the universe itself, the big bang, and life.  This essay is not the place to go into either, but it is the theme of my book “God, Causal Closure, and Free Will” linked above.

Note: On the subject of animal mind

Since mind is associated with brains we might speculate about where it appears in the development of animal nervous systems. The short answer is I do not know but at least it seems to be present, a “what it is like to be” subjectivity in all the mammals and birds and possibly all vertebrates. If Cosmic Mind is all of a piece, everywhere uniform throughout the universe, how is it that animal consciousness seems less rich than the human? The answer here is on the brain side. The electromagnetic field is filled with information all jumbled together. It can be made coherent (by radios) through the process of tuning. When a radio is tuned to a particular “carrier frequency” amidst the jumble, all of the electromagnetic modulation around that frequency can be detected and interpreted say as music from one, speech from another and so on. But notice also, that even if we single out a particular carrier, radios can vary widely in the quality of their conversion/reproduction. The sound emerging from older, more primitive, radios contains less of the information than that coming from newer more advanced electronics.

Cosmic Mind need contain only one signal. Being non-material it might as well be undifferentiated as we couldn’t measure any differentiation anyway. But there are, like radios, brains of various qualities. Like an older radio, the mind evoked by the brain of a mouse is less rich than that of a dog, the dog less than an ape, and the ape less than a human all bathed in the same field. This seems to be the case for consciousness as a whole, but is not the case concerning specific qualia. A dog’s aroma qualia are far richer than a human’s, as is a bird’s visual qualia (birds have four types cone cells in their eyes supporting ultra-violet visual qualia). There is nothing surprising about this if qualia in particular are closely tied to the physical root of the subjective arena. Some more primitive radios can be optimized to reproduce a narrow range of audible frequencies better than a more advanced radio even though the latter does a better job over-all.

In accounting for this difference this “Cosmic Mind” hypothesis at least matches the accounting for qualia by panpsychism and monisms. In the latter theories, more primitive brains produce less rich phenomenal qualities from the basic proto-phenomenal building blocks but nothing blocks optimizations in different brains. In both cases, the onus for the quality (richness) of qualia lays with brains. But the quasi-materialisms cannot so well account for intention, purpose (something the higher animals clearly have), unless one posits its proto-presence as well. This move puts teleology firmly back into physics, and in that case we are half-way back to theism.

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 problems with both of these ideas, but this is not for a review and Kastner is sedulous about these 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.

Why “One Size Fits All” Ontologies Never Work: Horgan, Harman, and DeLanda

There are three books from contemporary philosophers advocating for “one size fits all” ontologies. Each of them is strikingly different. In this commentary I’m going to focus on the meta-philosophical issue of a problem common to all of these ideas and by extension, all “one size fits all” ontologies. Ontologists do one of two things. They describe or catalog “what exists” or “what is real”, or they try to say something about the foundational qualities or properties of reality; what is “most fundamental” about what exists. All three of these philosophers are doing “what exists” sorts of ontologies.

As always, the three books I discuss are listed below with links to their editions on Amazon. Each title (except Horgan, I’ve linked my separate review of him here) is followed by the text of the review I posted to Amazon. I write these commentaries because their issues are out of place in a book review as such.

I’ll begin quickly with Terrence Horgan whose book “Austere Realism” I’ve reviewed separately (see link above). Horgan is the extreme minimalist. There is for him only one object that fully exists in the universe, and that is the universe in total (he calls it the ‘blobject’). Everything that we humans envision as existing (atoms, stars, animals, artifacts, and our own minds) exist only as affectations of language, a “fashion de parler”. As affectations, and for pragmatic purposes such “existence talk” is all well and good, but it is false to move from there to an ontological commitment; to the literal existence of any of these things. But Horgan is also a realist. The differentiation within the blobject (or of the blobject) are real. They are “mind independent differentiations” of the blobject. They are not “objects in their own right” but merely variations in the one object.

I’ve written before about Graham Harman here, and his collaborative work with DeLanda here. But I haven’t written about this particular book, “Object Oriented Ontology” in which Harman tries to address an issue I brought up in my review of other books, his “ontological idea” seeming to pop out of nowhere. In this book Harman describes more or less where his OOO idea comes from. It reinforces my idea that while proclaiming himself a realist he somewhat straddles the line between realism and anti-realism.

Harman’s approach is exactly opposite that of Horgan. Everything, stars, governments, ideas, relations between ideas or things, arbitrary sets, fictional characters, events, all real, all distinct objects. His is the ultimate ontological plurality but he is careful to say that while all are objects, not all objects are of the same sort. Some for example, like fictional characters, are real yet do not exist. Harman’s goal is a univocal causality. If rocks, governments, corporations, and ideas can be causes what does this say about the nature of causation in general?

Of the three authors, DeLanda’s ideas are the easiest to reconcile with common sense. Basically he observes that most differentiated things in the universe are composed of other things. They have parts that are extrinsic to the phenomenon of which they are parts. That means such parts can be removed and replaced by something similar (but not identical) and still retain their identity. In addition, these things composed of parts can become parts of other wider or larger things exhibiting new causal potentials.

As concerns ontological commitments, for Horgan, planets and governments do not exist as such, only the blobject actually exists but it happens to be differentiated into recognizable particulars that we can label in any way we see fit for pragmatic and scientific purposes. Horgan is interested mostly in what makes scientific discourse (say about stars) true even if stars do not, strictly speaking exist.

DeLanda agrees with Horgan that governments and stars do not belong in a strict ontology. What exists are assemblages each existing in a hierarchy of assemblages. Presumably the hierarchy goes all the way up to Horgan’s blobject, and all the way down to protons. But DeLanda does manage to clearly distinguish between social assemblages having physical expressions and potentials (governments, banks), and physical assemblages like stars and galaxies. What is important in both cases is that it is the assemblage that has ontological gravitas because it has causal potentials whether those are the potentials of a government or an asteroid.

Neither Horgan nor DeLanda are “essentialists” as concerns either what does or does not “strictly belong” in an ontology. There is no “hidden center” or essence to what belongs in ontology. If we had a complete description of everything (which for various reasons, linguistic, and perspectival, we cannot have) we would have fully exhausted being. Harman says no, that each object has an essence or being that we cannot even in principle ever exhaust. This includes “real objects” that do not exist like fictional characters. It is precisely this essence to which an object’s qualities are attached. Like objects have like qualities but their essence makes them individual. Objects are not merely “bundles of properties” described by a spacetime worm. Properties inhere in something and the being of that object, what makes it real, is whatever that something is.

Horgan is after the truth and meaningfulness of scientific discourse. He establishes this even in the face of his extreme ontological claim, and I believe this may be his point; “even given the blobject, science can be true”. Harman is after causation and he gets there but at the cost of an ontology as copious as Horgan’s is sparse. To make it all work, Harman’s objects must be divided up in various ways, much depending on what amounts to the classical distinction between mind and the mind-independent world. Harman does give us a nice account of fictional characters, but not really different from yet another “new realist” Maruzio Ferraris (reviewed here) who gives us the same account without the causal metaphysics. I am not sure how DeLanda would handle fictions. They surely have expressions in the physical (books, films) but I am not sure they could be said to have causal properties of their own. Certainly not outside minds that encounter and interpret the physical expressions.

Horgan and Harman are the two strictest “one size fits all” ontologists, DeLanda is less so, but even viewed as a one size fits all proposal, assemblages require little ad hoc maneuvering (Harman) or stipulation (Horgan and Harman) to fit in with most if not all of our experience. The common sense fact is that almost everything is made of other things. None of these views address mind very well though to be sure all are implicitly physicalist so brains are surely objects, assemblages, or proper differentiations of the blobject.

Harman, taking us back to Heideggar, claims that the contents of consciousness are all objects. This works fine as concerns sensory representations, even beliefs and memories. It is less clear how attitudes and intentions are objects. To the extent that both amount to ideas they have an object-hook. Both intentions and attitudes have causal properties. Ideas can lead us to actions. If that qualifies them for object-hood, so be it.

DeLanda’s ontology is “one size fits all” in the form of things and not the things themselves. He does not insist that literally everything real (fictional or otherwise) is an assemblage. By contrast Harman and Horgan do claim that their ontologies cover everything. That they likely do not is demonstrated by how they must each be twisted to make them work. For Horgan, scientific truth, even epistemology in general, floats free of the “true ontology”. For Harman, objects must be distinguished into partly overlapping classes or kinds, universals like existing and non-existing, symbiotic and dormant, real and sensual (both of these last categories real in the strict ontological sense), and so on.

Only Horgan claims there is literally but one existing thing. Harman counts literally everything (remember even thoughts and arbitrary relations) as real objects but must then divide them up into many categories to make the idea come out. Why not merely objectify the category and claim that these universals are the foundation of the real? For DeLanda it is a structure of relations that is [almost] universal, but what emerges from such a structure is, like Harman, both distinct and real provided we are careful to distinguish between the abstraction naming it (star, or government) and the reality (an assemblage) of its composition and history.

Horgan and Harman are “ontologies of the now”. Neither takes much account of time. Time is involved in the differentiation of the blobject (Horgan) of course and objects (Harman) come, go, and change through time, but neither theory demands time to make its basic point. Only DeLanda’s ontology demands time because both the coming-to-be of assemblages and their impacts have intrinsically temporal dimensions. Assemblages include as a proper part their own history and possible future effects on events, other assemblages.

Though each of these ontologies are different they all suffer from a species of triviality. If literally everything is an X, then to say that “only Xs exist” is a difference that makes no difference. Horgan shows that scientific truths can remain firmly grounded even in the face of a stipulated truth: “all is one”. Harman’s idea is also, ultimately, a stipulation. He can’t really deliver an equivocal causation, only one that can be “thought of” like that. If all cause lies between categories (the real and the sensual) that doesn’t tell us much about it. It also might be that there is something important about the difference between the categories and not merely the objects in them. Non-arbitrary categories (perhaps material particulars and some universals) might indeed exist, while arbitrary ones (random sets, trivially contingent relations — “taller than”) do not.

Harman’s distinction between the important and the trivial is also arbitrary. What appears dormant or unimportant from our perspective might be symbiotic from another. DeLanda’s triviality is a little different. Remember that each of these philosophers is a materialist and so ultimately, whatever should be both “real and exist”, it must begin with atoms that are surely assemblages. So while Harman and Horgan’s ontologies ultimately come down to stipulations, DeLanda’s, by contrast, is observational, and if he is right, if everything is some part of everything else (the universe at least), his observation must be true (at least of the material world) and so is also trivial.

In the end none of these “one size fits all” ontologies fit the universe of our experience because the universe is not a one size fits all arena. If there is a God then there are three fundamental mind-independent joints in reality (see Prolegomena to a Future Theology), spirit, mind (not individual minds but the phenomenon of mind in general), and matter — the material world experienced by individual minds. Even if there is no God and individual minds emerge only from the functioning of brains (i.e. brains are sufficient, a dubious proposition disallowed by physics — see Fantasy Physics and the Genesis of Mind), it is prima facia absurd to assert that mind is material, even more absurd to say it doesn’t exist. Individual minds, once emerged, have an impact on the unfolding of events. Mind is not physical and yet causally efficacious notwithstanding that what propagates its causal effect in the physical is a physical body controlled by a mind.

Aside from these three authors (Ferraris does not try to construct a universal ontology) I haven’t encountered another “one size fits all” ontology. If I do in the future I am confident that like these three any truth it contains will be but a trivial truth.

Assemblage Theory by Manuel DeLanda 2016

Manuel DeLanda’s book is a mature attempt at explaining what “assemblage theory” is and its relation to the philosophical sub-discipline of ontology. Assemblage theory can be applied to other philosophical domains but first you have to understand what it says about what there is. To put it in its simplest form, most things in the world are assemblages. They are (1) made of parts that might be exchanged for sufficiently similar parts (parts are “extrinsic”), (2) have properties and potentials that the parts do not have other than as the assemblage, and (3) they can, in turn, become parts of larger assemblages having novel properties and potentials in part made possible by the contribution of its sub-assemblages.

Assemblages are rather intuitive in fact. We are all familiar with many of them. We are a part of some of them, and it is natural to see in the world differently scaled phenomena (from atoms to galaxies, even the universe) that all appear to be assemblages. DeLanda then begins from a place that matches most intuitions about the world, and he does not insist that everything that is MUST be an assemblage. There are things of the world that are not, but by-in-large very much of our familiar world consists of assemblages.

DeLanda then explores many of these familiar things as encountered through human history. He explores tools (machines), people themselves, language, cities, society, wars, and so on. A particular point he wants to make is that every noun I used in the last sentence is a made-up “making real” (reification or “to reify”) of things that don’t really exist simpliciter. DeLanda understands that to make up these concepts is perfectly legitimate for ordinary discourse, but he is not committed to “their existence” as these things. Rather his commitment is to the assemblages from which they are composed and the higher-level assemblages they can and do contribute to composing. To understand an assemblage we name, “the government”, or “the market”, we really have to understand what it is made of (more assemblages) and how it comes to affect the wider world, other assemblages in which it participates. It is the assemblages and their expressions that “are real” as far as ontology is concerned.

The examination of human institutions is followed by a chapter on the doing of science; the best encapsulation of “philosophy of science” I’ve read! He moves down from social reality to particles, atoms, and molecules in order to introduce us to the concept of a “diagram” by which not only can assemblage be described (its history) but also what future paths in could (possibility) and is likely (disposition) to follow. DeLanda moves away from social phenomena for the sake of simplicity. Future paths for a molecule are vast but still restricted compared to that of a city or person. In theory it is simpler to understand what he is driving at on this level and its significance can be felt in philosophy and other disciplines. Importantly, the same principles apply whether we are talking about a protein or a nation.

He gets a little technical here in the last chapters. Simpler or not I could follow all of this only because I’ve had just enough mathematics background to get the difference between the levels and types of mathematics he talks about here. Some readers will have trouble with this though DeLanda nowhere USES mathematics; there are no formulas or mathematical demonstrations. His aim is to show us that there are mathematical tools that can be applied to assemblages describing their history as well as dispositions and possible futures. DeLanda is keen to show that assemblage theory as philosophy is (can be) firmly grounded in mathematics. Again as from the beginning, this makes intuitive sense. That mathematics can be applied to the regularities of the universe is well known. If those regularities are “qualities of assemblages” it makes sense that math can be used to describe them.

All of this then comes together very well in this book. I have read and reviewed others of DeLanda’s books, but this is the one to get if you want a grounding in his idea from the fundamentals on up.

Object Oriented Ontology by Graham Harman 2018

In reviews of earlier books by Harman I complained that his “object oriented ontology” (OOO) seemed to pop out of nowhere. He never (before) tells us how ideas preceding it, those of other writers, built up to his central insight. He seems to be making an attempt to correct that lacuna in this book. I think he succeeds in the effort to enlighten us about OOO’s origins, but my issues with the substance of the theory itself are not here resolved.

Harman begins by introducing a distinction between truth and knowledge along with their relation to the doing of philosophy. For him philosophy is not about truth or knowledge though it seeks and approaches both. Instead it is about reality which cannot, nevertheless, be approached directly but only indirectly. With this he begins to give the reader an introduction to his version of realism which is not very realist as I understand that term. But nor is Harman an anti-realist in the traditional sense. Rather he seems to straddle the fence.

The mind independent world is perfectly real and filled with particulars (objects), this being the realist thread. However we never encounter those objects directly but through their qualities, sensual qualities (he should have used the word ‘sensuous’ here not ‘sensual’ but I’ll let you look up that difference), which are qualities of the object as it is reflected in the content of our consciousness. The tree in the yard is a real object. The tree in my mind is its sensual counterpart. But neither the tree in the yard, nor the counterpart in our mind ever reveal themselves fully to us. They are “real”, but their core is always hidden. This is the anti-realist thread in Harman.

In Chapter two Harman gives us the key insight that also belies his Continental inclinations. Philosophy is metaphor and theater. He doesn’t mean here play acting. He means that to do philosophy the philosopher must replace the metaphor with herself to understand what it reveals about the real object. Even the metaphor never completely succeeds in exhausting the object, but it gets us further into it than does any literal or scientific statement. Harman knows that language is metaphorical. In fact (for Harman) the literal tells us less than the metaphorical. No word or collection of words captures everything about that which they denote. But he rejects the notion that language alone is responsible for failing to grasp everything. There is always more to the object, real or sensual, than we can ever know.

From this beginning he investigates social and political discourse and then returns to a more detailed view of objects (real and sensual), their qualities, and the relations between them. Harman divides his ontological universe into four different types, the real and sensual objects, and their real and sensual qualities. He does a pretty good job on the objects and the sensual qualities, but I have trouble understanding what a “real quality” can be since like the real object, real qualities also withdraw from direct contact. Harman does a good job of analyzing fictional objects, and we are introduced to his distinction between passive and symbiotic object-relations. Again (as in other of his books) Harman insists that symbiotic is not only about importance to humans, but in fact it always seems to end up being that in the final analysis.

His ultimate target in this part of the book is physical causation (like two billiard balls colliding, though the idea is supposed to apply to causation of all sorts). Even billiard balls do not make contact directly but through their sensual qualities. This part of OOO makes no sense to me unless “sensual qualities” are taken to be something independent of mind. I suppose this interpretation is possible, but Harman does not make his thought clear here at all.

The book moves then to challenge some of Harman’s peers who have accused him of stealing ideas from others. He focuses on Deleuze and Foucault arguing that their views, which some have taken to be foreshadows of OOO are not really that at all. Following this he reviews the work of a number of young philosophers who have broadly adopted an OOO orientation. Harman does a good job here of sketching both the similarities and differences between his work and the others reviewed.

It is not until here, near the end of the book that Harman lets drop his disdain for matter something strange for a realist. He explains himself a bit more in the last chapter, but his explanation fails to bridge a gap. It may be true NOW that there is no undifferentiated matter in the universe. Everything is differentiated and hence all are objects. But this was not the case in the opening Planck times of the universe when there was nothing but undifferentiated radiation. Harman’s ontology, even if it captures the universe’s present (and I don’t think it really does) misses its history, something for which ontology should surely account. In this latter part of the book he also lets slip that all relations between objects are also objects. He has said this in other books, but other than this one parenthetical aside, he doesn’t elaborate on this claim at all.

In the end, this book does the job of explaining the origin of Harman’s OOO idea and some (but not all) implications. I remain not a fan. There is too much about OOO that seems ad hoc to me, but after all, differences of opinion are what keep philosophy going and as Harman notes at the very beginning we do not get all the way to knowledge or truth, but only aspire to find ways to get closer to both.

Book Review: “Ontology and Metaontology”

As with most of the philosophy I review there are matters, lines of inquiry, alternate points of view, that illuminate more to be done, or resolve issues raised, that are not appropriate in the context of a book review. A review should focus on what the author says and perhaps how (s)he gets to what is said, not on differences of opinion between author and reviewer. And so I publish book reviews on Amazon, and then republish them here along with a link to the book for my reader’s convenience, and commentary whose purpose is dredging up those differences of opinion.

The first question that comes to my mind is the relation between metaphysics and ontology. The authors do not address this very much other than to say that the latter is usually considered to be a sub-discipline of the former, but no relation is clearly delineated. As a result an issue I noted in the review is the authors attribution to ontology (an alternative “fundamental question”) of a question I normally associate with metaphysics; the “fundamental ground” of what is real. If ontology is about “what is real” or “what exists” independent of mind (including such mind-managed entities as propositions, numbers, and sets), it only gets to be about the fundamental ground of what is real if, as some ontological systems do claim, that fundamental ground is the sole existent entity, everything else being nothing more than various assemblies of it and “are real” only in a derivative sense.

But while trying to understand what might be real even of the assemblies (natural and artifactual kinds for example) surely mind itself is among the [presumably] “natural kinds” for which we must account. Drs. Berto and Plebani ignore this singular question choosing instead to narrow their survey to a few well-worked channels of thought about reality “besides mind”. Idealism (everything is mind) is ignored because their focus is on what can be said of “mind independent” reality. Taking for granted that there is such a thing, we can characterize it in variously useful ways, and thus reject idealism. But even if idealism itself is false, the question of what exactly mind is matters a great deal.

Natural kinds like stars and animals, and artifactual kinds like chairs and statues are, after all, physical particulars while propositions and numbers clearly are abstractions and the mind-independent status of abstractions surely depends on the status of mind itself? If mind “substantively exists” then we can argue about the ontological status of abstractions. If mind does not exist (eliminative materialism) or is merely epiphenomenal illusion, then abstractions cannot in principle have any “mind independent” status.

On the matter of “fundamental ground” there is no explicit discussion of the distinction between substance and process ontology. The authors come at their subject mostly from a “substance viewpoint” but they do also address the ontological status of events which are processes. They address the causal status of agency versus process in events, but the chicken and egg problem (are all substances process or is process merely the causal interaction of substances) is not specifically covered.

I have another small issue with this book. When reading books on ontology written in the last few years (this one in 2015) I look for references to E. J. Lowe who, in my opinion, was among the best thinkers on this subject (he passed away quite young in 2014 or so). I rarely find him, but these authors do cite him (from a 1989 book) in their examination of particulars. But the authors discuss not only particulars, but kinds (classes), tropes (or modes), and global universals (all are after all well-worn ontological subjects). Yet they make no mention of Lowe’s “Four Category Ontology” (2006) in which he brings each of these four elements into harmonious and logically consistent relation. Of course Lowe’s is but one idea among many, but it is the only recent treatment (and I have looked having read many of the authors they cite in the text) that so neatly ties them all together. There should have been at least some mention of Lowe’s book.

Meanwhile, despite these shortcomings, this is a good read. The authors address only a tiny slice of the whole ontological field, but they do a good job with that slice, broadly illustrating how ontology is done and the salient factors that enter into it.

Ontology and Metaontology by Francesco Berto and Matteo Plebani (2015)

I’m not much for reading “overview books” in philosophy, they tend to be over simplistic and misrepresent as much as they enlighten. Once in a while a title appeals to me and this one looked rich enough to be worth a read. It was.

Dr.’s Berto and Plebani (“the authors” from here on) begin very deliberately setting out the distinction between ontology from metaontology. The former (covered last in the book) is about answering the question: what things are there in the universe, or what kinds of things are there, and are “kinds” (for example) among the things there are? As it turns out trying to answer such questions, since they are so fundamental to what we take our experience to be about, raises many questions of procedure. From what set of assumptions do we begin to address such issues and by what methodology? These latter questions are the subject of metaontology.

In a moderate length book covering a 2500 year-old field, the authors cannot possibly address all the viable proposals for answering these questions. They choose several lines of thought taken to be the dominant contemporary themes of the field in the analytic tradition and follows them out. Beginning with what they entail for the procedural questions, and then using each of the various meta-positions to address the main questions of ontology proper: material things (natural and artifactual), abstract things (propositions, numbers, sets and classes, fictional characters), and events. They do a superb job tying the procedural approaches covered in the first half of the book to the meat of the subject in the second. They never answer the question “what is there” but then they are not advocating a particular ontology, rather showing how the possible set of answers follow from different approaches to the subject. The book illustrates how different meta-approaches affect the possible range of answers to the ontological questions themselves. He is successful here, but the reader does have to pay attention.

There are a few holes (and yes the ontological status of holes is addressed) in the presentation. Ontology is a sub-discipline of metaphysics and the authors do not ever clearly distinguish between them; not that this is easy to do in any case. For example, they present “grounding theories”, as the idea that the big question of ontology is not “what there is” but what is the “fundamental ground”, the “basic stuff” of “what there is”? As I understand it, the matter of grounding is the core of metaphysics and not ontology per se, though to be sure the line between them is very ill defined. They also note from the beginning that matters of mind are not at issue. Propositions and the quality of redness are mental phenomena. The ontological question is would we still, hypothetically, count them as entities in the universe if minds did not exist? Fair enough, but the ontological status of mind itself is controversial in philosophy. Some discussion of this question from the viewpoint the metaontologies he covers would have been interesting.

In the telling of all this, the authors include many dozens of references from philosophers of the 19th and (mostly) 20th Century. The book’s bibliography is a who’s who of metaphysical and ontological thought, and yet there is far more left out (God theories, ontological commitments in Continental philosophy, or Eastern philosophies are ignored) than included. Again I do not fault the authors for this. They had to find a way to narrow the material or the book would be a thousand pages long. This is a superb book for philosophy students at the undergraduate level who have an interest in these questions. It can be read by anyone however and does not presuppose any familiarity with the presented material.
