Hello, dear readers. I have another round of Really Recommended Posts to share with you this week. I hope you enjoy them as much as I did!
The Knower and the Known- Interview with Stephen E. Parrish– Stephen Parrish is a Christian philosopher who has written a wonderful tome on philosophy of mind. Here’s an interview with Parrish about the central themes of the book. See also my review of the book. I’ve read it a few times now, and it is phenomenal.
Ben Hur: An Epic Movie of Christian Forgiveness in an Empire of Hate– A great look at the Christian themes that can be found in the latest iteration of the classic story of “Ben Hur.” Also check out my own reflections on the film.
Obama’s Pardons– Whatever one’s political affiliation, I believe this post from Thinking Christian will be a thought-provoking read. It is by someone who was incarcerated, and speaks to the real injustice in some portions of the United States’ criminal justice system.
Science and the Optimistic Naturalist– Is it truly rational to punt to possible future scientific understanding to answer what are currently understood as metaphysical questions?
Sunday Quote!- The Failure of Eliminativism for Explaining Mind
Every Sunday, I will share a quote from something I’ve been reading. The hope is for you, dear reader, to share your thoughts on the quote and related issues and perhaps pick up some reading material along the way!
The Failure of Eliminativism for Explaining Mind
Philosophy of mind has long been an interest of mine that I have read extensively on. Stephen Parrish’s The Knower and the Known remains what I consider the most valuable single-volume resource for outlining and refuting various physicalist and materialist varieties of philosophy of mind. I have been re-reading the book and come across many excellent arguments once again.
One example is the section on eilminativist views of the mind. According to those who hold this theory, at the most basic level, things like beliefs and consciousness simply don’t exist and are instead relegated to “Folk Psychology.” Parrish’s critique is incisive. He writes:
One cannot, in the making of theories, coherently deny that there are theories and theory makers. One cannot, in trying to understand something, coherently deny that there is such a thing as understanding, and that there are conscious selves who understand. One cannot try to make reality intelligible by denying the very notion of intelligibility. Yet it is precisely these things that eliminativists attempt to do. Therefore, belief in eliminativism is self-refuting and cannot possibly be true. (139, cited below)
Of course, this argument is not one that is unanticipated by eliminative materialists like Patricia and Paul Churchland. Parrish deals with their counter-arguments at length, but the most pressing problem remains that their position effectively is impossible to maintain, for it denies that it can be believed itself.
I’d highly recommend The Knower and the Known to you, dear readers, if you’d enjoy a lengthy, deep treatment of this and many other related issues. Check out my 2 part review (part 1 and part 2) for more analysis.

“The Knower and the Known” by Stephen Parrish, Part 2
Stephen Parrish’s The Knower and the Known
Thought and Consciousness
What does it mean to have a thought? Parrish notes several aspects which go into the very act of knowing. There must be an object of knowledge; there must be a subject to consider the object; there must be consciousness in order to apprehend concepts and aboutness; there must be a relationship between subject and object and consciousness; there must be understanding of that relationship; and finally there must be a view of the world in which all of this can occur.
Consciousness itself is an extremely complex notion which involves phenomenality: the actual experience of thought; intentionality: the turning of one’s thoughts to consider an object; subjectivity: an agent which is itself the subject of the thought; and rationality: the capacity to order thoughts in such a way as to make sense of them. (206-213).
Consciousness has certain phenomenal properties. That is, when we consider our own thoughts, there is a distinct feeling to them which allows us to differentiate them from simple sense perceptions. There is an aspect of inentionality or attending-to our thoughts which is itself irreducible. Moreover, we are able to comprehend things which are themselves non-physical, such as the nature of a logical argument like modus ponens (226-228).
Consciousness must somehow interact with the physical world. If one is a physicalist, it becomes a matter of reducing consciousness to purely physical explanations, eliminating consciousness, or offering a brute relationship between consciousness and the physical world.
Qualia are also extremely important when considering consciousness. How is it that we are able to see objects as objects with certain properties? What process allows for individual particles/rays of light to manifest themselves in phenomenal consciousness in such a way as to provide a coherent picture of an object? Moreover, “there is more to recognizing qualia than just having color in one’s sensory field; there is also our attention to said qualia, the judgments we make about them, the objects that they represent, and also our memory of them–and these factors can make all of the difference” (257).
Subjectivity is also extremely important to forming a theory of consciousness. It seems that subjects are, in fact, irreducible. For the physicalist, the concept of a subject is extremely difficult. After all, a subject at t1 is going to be different from that subject at t2 in a number of highly relevant physical ways. Their neurons are firing differently from t1 to t2. How is it that subjectivity is maintained. The substance dualist holds that subjectivity is maintained through unity of consciousness which may not be reduced to the physical (291). The unity is preserved through intentionality but more thoroughly through rationality. The use of reason is one of the primary ways to offer continuity of the self. For the subject, S, at t3 is considering both thoughts at t1 and t2 in order to come to a conclusion at t4. Reason itself has aspects of intentionality which cannot be accounted for on a physicalist view of reality, for a physical object is capable of performing mathematical computations but not understanding the aboutness inherent in those computations (266-267).
Our Minds in the World
Parrish grounds his understanding of consciousness in a theistic worldview. There are numerous difficulties with an account of substance dualism which seem to only be soluble on a theistic interpretation. One of these is the problem of the interaction between body and mind. If God exists, then it seems inherently possible that a deity would be capable of forming the world in such a way that mind could interact with body. Parrish addresses several objections to the notion that an immaterial being could interact with a physical universe while also making an argument for non-physical selfs apart from God interacting in the universe (324ff).
The match of our minds with the world is something which must be accounted for. Parrish notes that if we ground ideal objects in an immaterial being like God, the difficulties with such objects existence and subsistence may be solved. Moreover, the glorious match of our mental life with reality is also explained, for a rational being is the source of all which we observe. If that is the case, then we no longer must appeal to simple brute fact to attempt to explain the phenomena of consciousness; instead, we may note that it is exactly as one might expect given theism (337ff).
And Then There was More…
Parrish concludes the work with a brief comparison of physicalism and substance dualism across multiple questions related to consciousness and the physical world. Finally, there are two appendices which address free will/agency and the theory of panpsychism, respectively.
Conclusion
In Part 1 of this review I outlined Parrish’s discussion of physicalism. Here, we have seen the structure of his substance dualism. It seems to me that Parrish’s deconstruction of physicalism is quite powerful. In particular, I noted that he makes a strong argument that physicalist theories ultimately boil down into either epiphenomenalism or mysterianism, neither of which is plausible. Moreover, his use of numerous examples and thought experiments throughout makes the work easier to comprehend while also providing a solid basis for grounding further discussions in philosophy of mind. Finally, the vast amount of research and documentation Parrish provides makes the work invaluable as a reference for physicalist writings alongside its clear value as a thorough critique of those same works.
The second major section, in which Parrish outlines his view of a theistic dualist ontology, is equally important. He provides a large amount of background for understanding how to put together various aspects of consciousness while also noting that, on theism, these observed phenomena cohere within an ontology, while on physicalism they are generally either discredited or ignored. The one thing the work may lack is a bit of cohesion in the section on substance dualism. Parrish has given a broad vision for how to hold a dualist ontology, but sometimes leaves it up to the reader to put the pieces together. The pieces are there, but not always assembled. I should note, however, that even here Parrish has provided an invaluable resource for those who wish to argue for a dualist vision of philosophy of mind.
I have already noted that Parrish’s The Knower and the Known is a tour de force in the realm of analyzing physicalist theories. However, the work is much more than a simple refutation of physicalism. Alongside that critique, Parrish has laid out the groundwork for substance dualism as a cogent alternative. Simply put, it is a must read for anyone with any interest in philosophy of mind. Comprehensive in scope, exhaustively documented, and interesting to read, The Knower and the Known is a must-have.

Book Review: “The Knower and the Known” by Stephen Parrish – Part 1
What is the mind? Are humans purely physical beings? What are we to make of physicalist/materialist philosophies of the mind? Do these debates have any relevance for the existence of God?
Stephen Parrish seeks to answer these questions (and more) in his work, The Knower and the Known
The work is split into two major sections. The first is an exploration of physicalist/materialist theories of mind; the second is an exploration of consciousness and how theism provides the best explanation for our phenomenal consciousness (among other things). We shall explore these in order. In this post, I shall focus upon Parrish’s critique of physicalism.
Physicalism
Parrish introduces the major physicalist theories related to the mind-body problem. These include reductionism, eliminativism, supervenience, and emergence. In order to make sense of the claim that the mind is a purely physical substance, it is important to come to an understanding of what it means to be “physical,” and Parrish cites numerous philosophers in order to come to a fairly simple working definition: “to be a material object (to be composed of matter) is ultimately to have certain kinds of causal power over certain areas” (69). The definition must, necessarily, be more complex. Thus, various aspects of dimension, space, and the like are explored. Then, KK provides an explanation of the standard materialist/physicalist view of reality, which is essentially that “everything that exists… can be located within space and time…” (85, Parrish’s definition cites that of C. Koons, and is also lengthier, but for the purpose of this review I have left it at this).
The nature of physicalism must also be understood in order to analyze the claims of physicalists. How is it, exactly, that the physical is to account for the mental? Parrish explores numerous ways proposed to explain physically the connection. These are centered around various proposed psycophysical laws, which hold that there are certain ways in which conscious states relate relation to other physical states. There have been many different proposals about how these laws might work.
According to the nomological theory, there is a lawlike correlation between conscious and other physical states. A nomological theorist would note the correlation between neurons firing in the brain and various mental states. The proposal would then lead to a law of correlation (and perhaps causation) for brain states b1, b2, and b3 with conscious states c1, c2, and c3. Parrish notes a number of problems with this theory, however. Most notably is the fact that there are sometimes different patterns of neurons firing for the same thought. Of course, a physicalist could counter that there are different laws for these different patterns as well. In that case, notes Parrish, “there would have to be laws to regulate the relation of every brain state with the relevant phenomenological aspect of thought to which it is correlated” (89-90). Of course, this becomes even more problematic when one considers that there is an infinite set of phenomenological aspects of our consciousness. That is, we can focus our minds around thinking of numbers and continue counting from one to a billion and beyond. For nomological theory to be correct, there must be a specific brain state for each of these thoughts (along with whatever different brain states would need to exist for the variations which can produce the same number). So there would then need to be an infinite set of laws to account for our mental life.
Yet there is another difficulty, for “since it seems possible for different types of brains to have the same conscious phenomenal thought, and every brain is constructed somewhat differently from every other brain, there would have to be even more laws that accounted for conscious items to accommodate all of the brain states of all the different brains” (90). To say that such a theory of mind begins to make a bloated metaphysics seems something of an understatement. And this is not to even begin to consider the possibility of other intelligent life in the universe, which would also need these lawlike relations for governing their conscious states.
And all of this is not to take into account the problems with explaining how and why there could be different patterns for the same thoughts not only across species but also across brains of the same species and also across individuals. A number of other possibilities are examined, including accidental correlation theory, realizability, and identity. Each of these comes with their own set of problems which Parrish elucidates (92-97).
Parrish throws the gauntlet at physicalist theories of mind in the chapter aptly titled “Judging Physicalist Theories of the Mind.” In this chapter, KK provides a thorough critique of all the major physicalist theories of mind. For the purpose of this review, I will only provide the briefest of summaries for each of these critiques. Mysterianism is essentially the notion that we cannot know how consciousness and the brain relate, but we do know that physicalism is true. The problem with this position is that such a position basically pushes the burden of proof unto other physicalist theories of mind as opposed to providing its own explanation, and the theory in fact seems to be just another form of epiphenomenalism.
Eliminativism is a simpler theory in which it is simply asserted that consciousness does not exist (133ff). Such a theory seems patently absurd on its face, yet some physicalist philosophers continue to maintain that despite any appearance to the contrary, “there are no conscious aspects, objects, properties, or events at all” (136). The difficulty with such a position is that it is “self-referentially incoherent” (137). That is, it cannot be consistently believed (whatever it means to “believe” something) that there are on mental state when, in order to have such a belief, one must have some sort of mental state. Parrish further offers a scenario to describe our world in terms of an eliminativist worldview, which would yield a kind of “zombie” world in which our fictional mental states have no relation to the world around us (149-150).
Identity theory basically asserts that consciousness just is identical to the brain. Much work must be done to analyze this theory by noting which theory of identity one might hold to, along with how such a theory of identity might play out. KK provides just such an exploration and comes to conclude that any of these identity theories falls to a number of objections, including the arbitrariness of the connection between the physical and the [identical] consciousness (162-163). Supervenience theory, which holds that somehow the mental supervenes upon the physical, suffers from providing no actual explanation for how this should be the case and thus basically devolves into one of the other physicalist theories.
Functionalism is the theory that “the conscious mind is the brain functioning in a certain manner” (171). Again, the difficulty here is that this seems to boil down largely into a bare assertion and how closely related to (and probably reliant upon) eliminativism it is.
Higher order theories of mind posit that consciousness is something like the brain scanning itself. However, this provides no explanation for how consciousness could arise and thus is again parasitic upon other varieties of physicalism, most notably eliminativism.
Epiphenomenalism is at the core of Parrish’s critique, for throughout the work he shows in numerous ways how the other physicalist theories of mind are ultimately mysterian or epiphenomenal in nature. Epiphenomenalism is basically the view that consciousness is causally inefficacious. Thus, it is the brain which “does the work” while consciousness is some kind of byproduct of brain activity. However, such a theory does not adequately explain how consciousness may itself arise, nor does it provide any attachment for our thoughts to reality. It thus suffers again from self-referential incoherence, for our mental states have no causal attachment to our brain states or reality. They are, again, merely “epiphenomena” which somehow are generated by our brains. If our mental states happen to line up with reality, that becomes a merely happy accident, for our mental states do not control our brain states but are rather generated by them. This is not to imply that mental states must control brain states to give rise to coherency, but rather to note that unless our mental states are causal in some sense, the very process of rational thought is illusory, for our prior mental states have no connection to our past mental states other than to be generated in a certain temporal order.
Conclusion
We have outlined Parrish’s critique of physicalism. Next week, we shall explore his defense of dualism and his case for theism from the nature of intelligibility. However, by way of conclusions for this section, it is important to note the insights which Parrish has offered in KK. The arguments he presented seem devastating to physicalism. In particular, the fact that so physicalist theories of mind all seem to either ultimately appeal to mystery or reduce consciousness beyond causal powers undermine the physicalists’ ability to explain reality sufficiently. If a worldview cannot even account for something as basic as our thoughts, such a deficiency seems to bode ill for the rest of that view. As noted, we shall note a powerful alternative which Parrish argues for in the latter part of the book, theistic substance dualism.
Parrish, of course, offers much more thorough critiques of every position listed here (along with many that were not included in this outline). The work is extremely important in not only its comprehensiveness but also its thoroughness for exploring theories of mind.
