physicalism

If materialism, are there subjects?

In this post I seek to establish one premise: If materialism is true, there are no subjects.

There has been much extended discussion in my post on atheism’s universe, wherein (in the comments) I asserted that, on atheism, there are no subjects. It is high time I clarified my position and drew out its implications.

Materialism and Atheism

My argument is based upon a materialist or physicalist view of reality [I use the terms 'materialism' and 'physicalism' interchangeably here--I realize they are sometimes used to delineate differences between hard and soft materialists, but for the sake of this post one may assume that any time I mention "physicalism" I mean materialism at large]. I am asserting that: if physicalism is true, there are no such things as “subjects.” I’ve briefly argued elsewhere (see the post linked above) that the only consistent atheism is materialistic. For atheists who are not materialists, I leave it to them to show that their view consistently allows for immaterial entities.

The Nature of a “Subject”

One constant objection to my position is that I never defined what I meant by “subject.” One reason I did not seek to define the term is because  I did not want the debate to boil down into a semantic war over the meaning of subject. There are some features of “subjects” which most parties agree upon, but how to lay out those features is hotly debated. Further, I did not wish to beg the question against the materialist by defining a subject in such a way that no materialist ontology could even attempt to approach it (suppose I defined a “subject” as a “wholly mental feature of reality which acts as the center of consciousness”; in such a case, I’ve added nothing to the discussion because I’ve excluded materialism from the debate without argument).

There is no easy way to define what is meant by “a subject.” I will seek now to define it as broadly as possible, so as to avoid any questions begged.

A Subject: 

1. Is the referent of the term, “I”
2. Endures from moment-to-moment as one being. A subject would be the same subject at T2 as it was at T1.
3. Accounts for any mental states–whether they are actually aphysical or physical.

Hopefully these terms are agreeable to both sides. I’m sure people on either side will want to flesh out the notion of “subject” more, but it seems to me that these points can be acknowledged by all. The first point seems to be fairly clearly true. It is “I” who experience x and not someone else. The second point is necessary for subjects because otherwise “I” would be a different “I” from T1 to T2, and in fact not be the same being at all. The third point, likewise, seems fairly obvious, because it seems mental life is what comprises a subject to begin with. Whether the image in my mind of a cat is a purely physical phenomenon or not, any theory of the mind must take it into account.

Materialism Fails to Account for One and Many

On materialism, what is it that is the referent of the term “I”? Is it my brain (only)? Is it my body? What am “I”? I will here offer a brief argument that no materialist account can take seriously the notion that “I” am distinct from other entities. It is, basically, an offshoot of the “one and the many” problem in philosophy.

Materialism holds that all which exists is matter. Thus, “I” am composed of matter. The problem is distinguishing between everything else and me, for ultimately “I” am just a rearrangement of matter. Suppose that all matter is referred to as (M), and I am referred to by (I). Ultimately, on materialism, (I) is reducible to (M), which is really just all real being on materialism. Why suppose there are separate entities, (I) and (I2) and (I3) when all are, ultimately, (M)? It is much simpler to just suppose that (M) is all and that (I), (I2), and (I3) are (M) in rearranged forms.

Now I don’t suppose for a moment this isn’t highly contentious. Some will come along and say that their own experience is enough to confirm that they are a different being from every other. But why suppose this? Ultimately, that conscious experience is reducible to the brain, which is reducible to matter, which is everything. On materialism, there really is just one “thing”: the material universe as a whole. The “parts” of this “thing” are ultimately reducible to smaller and smaller particles which comprise all the “things” themselves. Ultimately, all is matter, merely arranged in different ways at different times. I’m not suggesting that matter is some kind of single entity. It is particulate. But matter is also one kind of thing. Ultimately, on materialism, all things are just this kind of thing: material. The only way to differentiate between them is by time and place, but even then every individual thing is itself composed of particles of matter. All things are reducible to the same thing.

What can save materialists from this? Materialists would have to embrace a robust metaphysics in order to supply a way out for the problem of “the one and the many.” Yet it seems to me that no materialist can take seriously a robust metaphysics, because they would then have to posit distinctions between entities that are aphysical. Positing such entities or properties would be decidedly contrary to materialism. For example, one solution is that entities are distinct in that all share being itself, but they also have essences which distinguish them from other things (see Clarke, 72ff, cited below). For a materialist to embrace this, they would have to hold that each individual person has an immaterial essence which is such that it makes it distinct from other entities. But of course, that would fly in the face of materialism. It seems to me, therefore, that materialism has no way to answer the problem of “the one and the many.”

Materialism Fails to Provide Enduring Identity

On what basis can a materialist affirm that I, J.W., am the same subject now as I was 20 years ago? All my matter has been replaced. There is no material component of me which is the same as it was back then. Yet my experience tells me that I am the same subject.

How can materialists account for this?

One possibility is that they can simply point out that I am numerically identical to my past self. Although the individual pieces of matter which comprise me are not the same as they were 20 years ago, they were replaced only in portions, during which my body endured as a totality.

The difficulty with this scenario is that it only serves to underscore the problems with materialism. Imagine a mad scientist, who, over the course of a day, cuts my brain into 24 pieces. Each hour, he removes one piece of my brain and places it into another body, which has no brain. He simultaneously replaces the piece of brain with an exact molecular copy. After the day, there is a body which has my brain in it, and my body, which has a copy of my brain in it. Which is me? And, if that question can be answered on materialism (which I doubt), when did my body/brain cease being me and transfer to the other body/brain?

Materialism simply cannot answer these questions. The worldview is baffled by them. Yet in order for something to be a subject, it must endure through time. On materialism, I have not endured through time at all. My entire being–from my fingers to the hairs on my head to my brain–is material, and has been replaced by new material. Where am “I”?

Materialism Cannot Account for Mental States

There are at least five features of mental states which materialism cannot take into account. They are:

• The feeling of “‘what-it-is-like’ to have a mental state such as a pain”
• Intentionality
• Inner, private, and immediate access to the subject
• Subjective ontology which is irreducible to the third person
• They lack spatial extension, location, etc. (Adapted from Moreland, 20, cited below)

While delving into these in great detail is beyond the reach of this post, I have already addressed a few of them in my post arguing for Substance Dualism against Monism. It seems that, on materialism, one must embrace supervenience and epiphenominalism in order to preserve mental states. Consider the following:

When I experience thought A’, it is because of a prior brain state, A. My mental states are either identical to, or supervenient upon, the physical state of my brain. The problem with this is that it relegates mental states to epiphenomenalism… This is because the mental state is entirely dependent upon (or identical to) the brain state. On physicalism, a mental state does not occur without a brain state occurring prior to, or in conjunction with, it.

…If it is always the case that Brain state A=> Mental state A’, then Brain state A causes whatever actions we take, for the brain state entails the mental state, which itself is identical to or supervenient upon the brain state to exist. But then, if we cut mental state A’ out of the equation, we would still have Brain state A and the action. Thus, consciousness is entirely superfluous. (Wartick, http://jwwartick.com/2010/11/10/against-monism/)

Reflection upon the supervenience of the mental on the physical leads materialist philosopher Jaegwon Kim to writes:

To think that one can be a serious physicalist and at the same time enjoy the company of things and phenomena that are nonphysical [by this he is referring to consciousness, the causal powers of thought, etc.], I believe, is an idle dream. (Kim, 120, cited below)

Objections

Objection 1: One of the most common objections I have encountered when I reason in this fashion is the common sense objection: “I think, therefore I am a subject!” or, as one commented on another post, “I’m an [atheist]. I have meaning. It’s possible.”

Such notions are scoffed at by materialist philosophers. Paul Churchland, the famed materialist and philosopher of mind, writes:

You came to this book assuming that the basic units of human cognition are states such as thoughts, beliefs, perceptions, desires, and preferences.  That assumption is natural enough: it is built into the vocabulary of every natural language… These assumptions are central elements in our standard conception of human cognitive activity, a conception often called ‘Folk psychology’ to acknowledge if as the common property of folks generally.  Their universality notwithstanding, these bedrock assumptions are probably mistaken.

In other words, the notion that “I’m a subject! I have meaning!” is nothing more than a philosophical dinosaur, a remnant of our ‘folk psychology’ which we should cast off now that we know the truth of materialism. Those who object in such a fashion as materialists seem to be blissfully unaware that they stand aligned against the vast majority of materialistic philosophy of mind. They must justify their position, but cannot, as they arguments above have shown.

Objection 2: Neuroscience has shown that the brain is the center of consciousness. When we think things, we can observe specific areas of activity in the brain. 

This objection is clearly mistaken. The previous arguments have sought to establish the premise: On materialism, there are no subjects. I could easily grant Objection 2 without doing any damage to my arguments. Sure, when we “think thoughts” we may be able to observe effects in the brain. How does it then follow that “we” are subjects? All that this has done–assuming I grant it–is show that our consciousness is somehow related to our brains. It doesn’t demonstrate that mind is identical to brain, nor does it justify the position that “I am a subject.” In fact, it seems to undermine the notion that materialism can explain subjects, because it implies, once more, that “I” am reducible to “my brain” which is, of course, reducible to its component matter as well.

Conclusion: That There Are No Subjects on Materialism and the Implications Thereof

Any one of these problems provides insurmountable problems for materialists who believe they are, themselves, subjects. There is no way, on materialism, to distinguish the one from the many; there is no way for subjects to endure; mental states are reduced to causally inert epiphenomena; and there is no way to account for mental phenomena.

Thus, if atheism is committed to materialism, and materialism cannot account for subjects, it  follows that, without question, there is no meaning on atheism. There cannot even be subjective meaning, for to reference something as a “subject” is, itself, illusory.

Materialists: Where is hope? Look to the stars!

“[T]he Universe may harbor civilizations more intelligent than our own. Perhaps one day, through interstellar communication, some advanced civilization will help us resolve such age-old problems as war, famine, disease, overpopulation, misuse of natural resources, and human aging.”- John Oró, “Historical Understanding of Life’s Beginnings” (40, cited below).

Such is the hope of materialism. I’ve argued elsewhere that if all we are is matter, then there is no meaning. The pervasive response was that “we make our own meaning.” Leaving questions over the tenability of such a view aside, I have turned to a different, and interesting phenomenon: Where is there room for hope, within materialism? 

It didn’t take long to dig up some quotes. One of the classes I’m taking this semester is on the Origins of Life. A few books we were assigned for this class were from a materialist perspective. The quote above is from one of those books. It resonated deeply with me. Consider this: If all we are is matter, having arrived here by unguided, biochemical processes, living on a dying planet in a dying universe–where is our hope? One cannot turn to transcendence with such a worldview, but one can attempt to emulate it.

Such is the case found in materialistic literature. Such is the grand materialist hope:

We can look hopefully for our saviors from the stars. There must be more intelligent life out there, and they will usher in a new era, a near utopia wherein disease, death, war, and hunger are all eliminated. Our alien saviors will rush to our aide once they’ve found us on this dying rock, and we will worship them as we used to worship the mythic gods of old. 

But it is not just hope for the future which must guide us. Our realization that we are but one among many (and many who are probably smarter than us) must lead us to a new set of ethics. Oró writes of new ethical principles we must embrace: “Humility: The life of all cells descends from simple molecules… Hope: Someday we may communicate with more advanced civilizations… Universality: We come from stardust and to stardust we shall return… Peace: We should change our culture of war into a culture of peace” (Oró, 40-41 cited below). Humility, hope, peace, universality–these are all things Christians embrace also, but the materialist has redefined them. Our hope is not int the transcendent but in the here-and-now. Our hope, again, reaches for the stars.

But is this really a hope? We know the universe is dying. We know that, even were we to escape death, eventually the cosmic heat death of the universe would occur, and our ultimate doom is sealed. Should we hope that our alien saviors are also inter-dimensional travelers? Should we hope that they transcend space and time? I leave these questions open.

But the most interesting phenomenon in all of this is that the materialist has abandoned their presupposition. Rather than hoping for what is they hope for what we know not. They look to the stars, grasping at things unseen. Iris Fry, a professor at both Tel Aviv University and Technion-Israel Institute of Technology in Haifa and author of The Emergence of Life on Earth writes honestly and lucidly of the philosophical commitments of the materialist in this sphere:

[T]he realization that many non-empirical factors are involved in determining scientific positions and in the adoption of scientific theories leads to the notion of theoretical and philosophical decision, or commitment. Research into the origin of life and the search for extraterrestrial life are a clear case in point, because here the weight of the philosophical commitment is much greater than in more conventional scientific fields. As long as no empirical evidence of life beyond Earth has been found, and as long as no scientific theory has succeeded in providing a fully convincing account of the emergence of life on Earth, the adoption of an evolutionary point of view toward the question of life’s origin and the rejection of the idea of purposeful design involve a very strong philosophical commitment. -Iris Fry (283, Cited Below)

Ultimately, I think she is quite right. There is a philosophical commitment being espoused here, not a scientific commitment. Too often, materialists forget that, but kudos to Fry for honestly admitting it while also espousing the very commitment.

Where is our hope?

The materialist answers: The stars.

Is this really rational?

Cruel Logic: “Ideas have Consequences”

“No Apologies Allowed” put a post up with a link to a YouTube video called “Cruel Logic.” In it, a serial killer debates a college professor about ethics and determinism in a materialistic universe. Check out the original post and discussion here. I recommend his site because it has tons of thought-provoking imagery and links to videos.

Watch the video below: WARNING: VIDEO CONTAINS DISTURBING IMAGERY.

What do you think? Are these the implications of materialism? Are we merely matter, determined in motion and emotion?

Atheism’s Universe is Meaningless and Valueless

“‘Meaningless! Meaningless!’
says the Teacher.
‘Utterly meaningless!
Everything is meaningless.’” – Ecclesiastes 1:2

My most recent post on the problem of evil granting empirical atheism generated some thoughtful discussion. Most importantly, it lead me to the following argument:

1) On materialistic [I use materialism and physicalism interchangeably, as is common in philosophy today] atheism, all we are is matter in motion.

2) There is no objective reason to value matter moving in way A over matter moving in way B

3) Therefore, on materialistic atheism, there is no value or meaning

Premise 1 seems self-evident. Materialistic atheism, by definition, says that “everything is physical, or as contemporary philosophers sometimes put it, that everything supervenes on, or is necessitated by, the physical” (SEP, cited below). The physical world is matter.

Premise 2 also seems like it should need little defense, yet atheists continually come up with ideas to try to get around it. For example, one may argue that the subjective suffering of persons should matter. Yet I fail to see how this argument succeeds. Pain and suffering, on materialism, at most supervenes upon neurons firing in the brain (along with chemical reactions and other physical phenomenon). My question for the materialist is: What reason can be provided for favoring matter moving in way A (call it, the way neurons fire when someone is in a state of bliss) over matter moving in way B (neurons firing in the way which causes pain)?

One answer which may be forthcoming is that creatures and persons tend to try to get away from things which cause B. This argument fails to provide an answer to the question, because all it does is push the question back to a higher level. It would change to: Why should we favor physical observable phenomenon which don’t cause avoidance over those that do? Again, the avoidance of B would simply be matter moving in a different way. In order to make a judgment between them, one would have to reach beyond the material world and into the world of objective meaning and value; this is, necessarily, a world which is nonexistent on materialism. Even if one could provide an answer to this second question, say “We tend to not like B. Things we don’t like are bad”, then we would have a purely subjective reality. What of the serial killer who delights in torturing himself, causing things to B? What reason do we have for saying what he is doing is wrong, because, after all, he likes B?

Ultimately, on materialism, everything boils down to matter in motion. Making value judgments about matter in motion is meaningless.

But if everything is matter in motion, then there doesn’t seem to be any way to make value judgments. How does one value a rock over a stick? They’re both just stuff. But then, on materialism, people are just stuff to; albeit more complex. However, if you were to break us down into our ultimately realities, we are no different than the rock. We are matter organized in a different way. Why value us?

There is no objective reason to do so. Therefore, there is no objective meaning or value. Life is purposeless, meaningless, valueless. Atheistic materialism demands this bleak view of the universe. I’m not saying it’s a good reason to abandon that [un]belief. I’m merely saying that those who hold such a view must be consistent.

“Now all has been heard;
here is the conclusion of the matter:
Fear God and keep his commandments,
for this is the duty of all mankind.
For God will bring every deed into judgment,
including every hidden thing,
whether it is good or evil.” -Ecclesiastes 12:13-14

[In the comments, I have suggested that on materialism, there is no such thing as a subject. The claim has proven highly contentious, so I have created a post to clarify my position: http://jwwartick.com/2011/12/05/subjects-materialism/.]

The Case for Dualism: Against Monism

Substance dualism seems to be the most reasonable position when it comes to consciousness. I’m going to be exploring the reasons for this throughout several posts.

Substance dualism is the idea that our conscious self is a combination of both a physical and non-physical reality. That is, our consciousness is not just neurons firing in the brain, but also some kind of phenomenal self, which is separate from the physical realm.

One reason for holding to substance dualism is that it avoids the problems of monistic physicalism. Physicalism argues that our conscious self is literally the brain. There is nothing but neurons firing in the brain (okay, it’s a lot more complicated than that, but the general idea is that our brain is our “self”).

Physicalism, therefore, leads to a kind of monism–everything is matter. Depending on which physicalist philosopher one prefers, this can lead to all sorts of problems. We can see this when we examine what exactly composes a “thought.” On dualism, a “thought” is a non-physical, phenomenal experience of the “self”–which is generally referred to either as “mind” or “soul.” On physicalism, a “thought” is identical with a brain state.

In other words, on Physicalism:

Brain state A => Mental state A’

Brain state B => Mental state B’

And so on.

When I experience thought A’, it is because of a prior brain state, A. My mental states are either identical to, or supervenient upon, the physical state of my brain. The problem with this is that it relegates mental states to epiphenomenalism. That is, if a mental state is wholly dependent on a brain state, the mental state is superfluous. This is because the mental state is entirely dependent upon (or identical to) the brain state. On physicalism, a mental state does not occur without a brain state occurring prior to, or in conjunction with, it.

This, in turn, leads to epiphenomenalism because the mental state is, as  I said, superfluous. If it is always the case that Brain state A=> Mental state A’, then Brain state A causes whatever actions we take, for the brain state entails the mental state, which itself is identical to or supervenient upon the brain state to exist. But then, if we cut mental state A’ out of the equation, we would still have Brain state A and the action. Thus, consciousness is entirely superfluous.

Another problem with this is that it also means consciousness doesn’t have to have any connection with the actual world. Our brain states could be causing all kinds of wild mental states which are completely unconnected to what is happening outside of our “self,” but we would never know it or act differently. I could be having the mental states of pigs flying and eating buffaloes as I write this, but it wouldn’t matter because the brain state is what is causative. The mental state is simply a byproduct of the brain state. Or, we could all be zombies, without any kind of phenomenal consciousness, and yet still be performing the same actions.

Yet another problem, on the physicalist perspective, is that there seems to be no reason for our mental states to line up with reality. Why is it that despite the fact that our brain state is causing all of our actions, or mental state seems to line up with those actions? There doesn’t seem to be any reason our mental states should line up with reality. One response could be that we have no reason to suppose they do line up with reality, but then we have no reason to trust anything we “think” and should give up whatever positions we do hold.

Of course, monistic physicalism actually argues that there is no mental state A’ generated by brain state A, but I don’t see any reason for believing this is true, for they are of two completely different kinds. One is gray mush, the other is a phenomenal image of a cat. One is composed of neurons shooting impulses to and fro, the other is the idea that “I wish I had eaten breakfast.” The law of identity states that A = A. But, according to monistic physicalism, my gray mush/neurons firing = image of cat. This is simply false.

So, I have no reason to accept physicalism on any of these formulations, and every reason to reject it. Physicalism is epiphenomenal, gives us reasons to doubt our basic intuitions, and makes any thoughts we have completely arbitrary.

Naturalism: Self-Defeating, Unintelligible, and Ungrounded (Among Other Problems)

Naturalism is self-defeating.

Naturalism’s “Grand Story” (I’m unsure of who exactly coined this phrase) includes evolution as the means by which humanity arrived on earth. I’m not here to debate that. Rather, I think that Alvin Plantinga’s “Evolutionary Argument Against Naturalism” has some fairly hefty weight (see Warrant The Current Debate and Warranted Christian Belief for this argument). The argument basically goes like this:

1) On naturalism, evolution selected for our cognitive system

2) On evolution, it is what is beneficial for survival that is selected (with some exceptions–some animals are just unlucky)

3) Therefore, our cognitive system was selected for survival

4) What is beneficial for survival is not necessarily what is true (in an objective sense)

5) Therefore, we can’t know (on naturalism) that our cognitive system is truth-seeking

6) If we can’t trust our cognitive system, but we come to the conclusion that naturalism is true, then we can’t trust this conclusion

7) Therefore, naturalism is self-defeating

Now take 4). It seems to be clearly true that evolution does not select for true belief, if it selects for beliefs at all. Take an example I stole from Plantinga earlier (here)

“Tim the Tiger lover and Suzy the Warrior.

“Tim the Tiger Lover has formed false beliefs that a) wild tigers are warm and cuddly and b) the best way to pet them is to sneak away from them silently. Suzy the Warrior has formed the beliefs that a) wild tigers are ferocious critters and b) they must be killed to insure the survival of mankind.

“Tim and Suzy are walking through the jungle one day, when they spot in the distance a tiger. Now, Tim immediately begins joyfully sneaking away, believing that he will soon be petting that warm, cuddly tiger. Suzy dashes forward to attempt to strangle the beast with her bare hands. Suzy dies, though it seems clear that her beliefs were at least partially true (wild tigers are indeed ferocious). Tim, however, succeeds in escaping and surviving, despite this not actually being his goal.

“Now, on naturalism, it seems quite obvious that Tim has succeeded. He has survived, and will thus pass his genes on to the next generation. Indeed, it seems quite likely he will pass along his false beliefs as well. For let us modify the scenario only slightly and say that it was quite dark. While Suzy was being torn to bits by the tiger, Tim happened upon a tiger cub or some other beast he took to be a tiger cub. He immediately, happily danced with it and cuddled it for a while before sneaking away to go home, having quite happily reinforced his false beliefs. So Tim, with his false beliefs enforced by some data that they are in fact true (after all, he sneaked away quietly from the tiger and managed to pet tigers), also manages to survive, and therefore pass along his genes and his false beliefs” (Wartick).

To put it another way:

Take N to be metaphysical naturalism, P to be probability, R is the proposition that our cognitive facilities are reliable, and E is the proposition that our cognitive facilities have developed directly by way of the mechanisms to which contemporary evolutionary theory directs our attention.

Now P(R/N&E) seems to be low (see above). “One who accepts N… has a defeater for R. This induces a defeater, for him, for any belief produced by his cognitive facilities, including N itself; hence, ordinary naturalism is self-defeating” (Plantinga, 231).

Thus, it seems unlikely to me that naturalism can even find grounds for warranted belief on its own basis for warrant. But that’s not where the problems end. Naturalism has a major problem with consciousness.

Naturalism cannot explain consciousness.

I quote my fellow blogger, Chris Reese and outline what physicalist philosophers are saying about consciousness:

[P]hilosopher of mind . . . Ned Block . . . confesses that we have
no idea how consciousness could have emerged from nonconscious matter: “we have nothing—zilch—worthy of being called a research programme…. Researchers are stumped.”6

Berkeley’s John Searle says this is a “leading problem in the biological sciences.”7

Jaegwon Kim notes our “inability” to understand consciousness in an “essentially physical” world.8

Colin McGinn observes that consciousness seems like “a radical novelty in the universe”; 9  he wonders how our “technicolour” awareness could “arise from soggy grey matter.”10

David Papineau wonders why consciousness emerges: “to this question physicalists’ ‘theories of consciousness’ seem to provide no answer.”11

If, however, we have been made by a supremely self-aware Being, then the existence of consciousness has a plausible context.

Physicalism goes so far as to deny consciousness. I take it as self-evident that I do have consciousness. It seems entirely unintelligible to me to deny this. But then naturalists cannot even explain it. They are unable to understand it in a “physical” world. Perhaps the answer is that there is more to the world than the physical. But due to the presuppositions of the naturalist, they cannot accept this possibility.

Naturalism denies freedom of the will.

Freedom of the will is another problem for the naturalist. If all we are is, ultimately, matter in motion, then how is that we have freedom of the will? Since the big bang, matter has simply been bumping against each other in a way that was determined by the big bang. Every path is planned out by the laws of nature.

Thus, naturalism denies freedom of the will, it denies consciousness, and it refutes itself. These are but a few problems I raise against naturalism (see my other posts on the topic here and here). I thus deny naturalism its right for philosophical dominance of my (free) mind.

Scientific (Evolutionary) Explanations of Religion

It is baffling to me that some, particularly the “New Atheists” seem to think that if we were to find some kind of biological “hard wiring” into our brains of religious belief, it would prove that God does not in fact resist and that we are simply machines driven by biological and sociological means to believe in some mystical being.

Why is this? What is the reason that evidence for scientific accounts of the origins of religion would somehow undermine religion itself? There aren’t reasons offered. It is always just assumed that if science can explain something, that precludes any other kind of explanation. This is a blatant genetic fallacy, also known as the fallacy of origin. Explaining how some belief came to be does not mean that belief is false.

The argument seems to be:

1) If science can explain some belief as being hard-wired into the brain, that belief is false

2) Religion (supposedly) is hard-wired into the brain.

3) Therefore, religion is false.

Premise 1 is obviously fallacious by the genetic fallacy. Just arguing that some belief is hard-wired into the brain does not make that false. If something springs to mind because of our cognitive predisposition to believe something, that does not mean that this “thing” that springs to mind is false. We believe, for example, in the existence of other minds innately, despite being unable to enter other minds and show that they are operating in a similar fashion as our own (God is Great, God is Good 102).

Though the argument is trying instead to show that belief in God is not really due to the fact that God is actually there, but rather due to some kind of naturally arising belief that we have evolutionarily forced into our brains. Thus, when we experience something that we may take to be supernatural in origin, we are only taking it in such a way because we are genetically predisposed to do so. But again this is a genetic fallacy and it doesn’t actually attack the religious beliefs themselves.

It could just as easily be the case that the Bible and most of human history are correct when they assert that the natural world gives evidences of God’s existence, and that man can have natural revelation of God by seeing His works revealed in the world. Not only that, but it is clear that the argument in the above paragraph is wrong. Let me take an example from Michael Murray in God is Great, God is Good.

“I believe there is a deer in the neighborhood because I can see its tracks in the mud in my yard. I can’t see it directly, but I see things that are causal consequences of the deer’s presence, and this triggers in me a belief that it is around. What this line of argument does not see or even acknowledge is the possibility that the mechanism s that lead us toward belief in God might be, like the deer tracks, causal consequences of God’s activity” (103). Thus, the conclusion that God does not exist simply because we may have triggers in our minds that lead us to believe something is God’s activity does not exclude the existence of God.

There simply is no good argument against the existence of God that can come from some kind of scientific explanation of religion. All such arguments fall to the genetic fallacy or would seem to argue against any kind of belief formation based on cognitive evidences.

The Ontological Consequences of Naturalism

What does naturalism entail? This is largely a discussion of the ideas contained within the book World Without Design: The Ontological Consequences of Naturalism by Michael C. Rea. An outline of his ideas comes first, followed by a look at a critique of his work.

Michael C. Rea has lofty goals for his book World Without Design: The Ontological Consequences of Naturalism. He lays them out almost immediately: to show that naturalists are 1. committed to rejecting realism about material objects (RMO), 2. are forced to reject materialism,  and 3. cannot accept the reality of other minds (ROM) (Rea, 8).

Naturalism, according to Rea, is best understood as a research program. This he defines as: “a set of methodological dispositions” (Rea, 3). He argues that research programs cannot be accepted based on evidence, but can be discarded based on evidence. “[T]here is no method-neutral basis on which to assess the decision to adopt a particular research program” (Rea, 7). He pushes for acceptance of this view of naturalism as opposed to epistemological, metaphysical, etc. naturalism. While I believe that naturalism can certainly be viewed as a research program (using his definition), I think it is unclear from his arguments as to why exactly the other views of naturalism are to be rejected. Interestingly, however, it seems that Rea’s definition of research program manages to include these various types of naturalism.

Whether or not Rea is successful in his arguments to refocus naturalism as a research program, his arguments stand, as they are directed at this kind of “naturalism-at-large.”

It is important to note that a central concept that must be understood in order to discern Rea’s argument is that he is almost certainly attacking what seems to be most naturalists views that naturalism is unapproachable. Rea’s argument for viewing naturalism as a research method becomes stronger when taking this into account–for if naturalism is accepted without justification, it fits his definition of research program. He quotes Quine (who is extremely important in many fields of philosophy [such as logic], not just naturalism): “The proper answer to questions like ‘What justifies me in believing what I learn by way of scientific method?’ is simply ‘Do not ask that question’” (Rea, 44).

I believe that this stance should be, at the very least, uncomfortable for naturalists, or at least naturalists who attack theists for similar responses as to justification for belief in God, but that’s a whole different subject. I believe that, however, both cases need at least some kind of warrant or justification.

But let’s delve into the meat of World Without Design. Rea, as was said before, argues that naturalists are forced to ontologically give up RMO, ROM, and materialism. What grounds does he have for making these claims? I was initially quite skeptical. Obviously, I have every reason to rejoice in any attempts to undermine naturalism, but to claim that naturalism cannot even justify reality about material objects is, as I said, a lofty claim.

Rea cites The Discover Problem as the main reason naturalists are forced to these consequences. The Discovery Problem is “…just the fact that intrinsic modal properties seem to be undiscoverable by the methods of the natural sciences. Modal properties are properties involving necessities or possibilities for the objects that have them” (Rea, 77). It is this Problem that Rea continues to press against naturalists, and after analyzing his exhaustive arguments, I believe he succeeds.

The problem is that science can discover, at most, extrinsic modal properties, but not those that are intrinsic. Rea frames one of the problems that follows from the Discovery Problem as follows (paraphrased): one man owes another a debt. When the one to whom the debt is owed confronts the debtor about it, he argues that he is not the same person he was when the debt was incurred, for, after all, large amounts of the molecules in his body are no longer there, or have rearranged somehow, etc. The one owed the debt promptly punches him on the nose (Rea, 79ff).

But how is it that one can prove he is the same person? What makes it so that the matter can be said to be arranged “human-wise” instead of merely “collection-wise“? The answer is modal properties. The problem, however, is that in order to successfully point to the debtor as being the same person, one must use intrinsic modal properties, which are undetectable via scientific method, and, according to naturalism, must therefore be rejected.

I can’t type out the whole book here for a number of reasons, so I’ll highlight a few arguments:

“[I]t is possible for belief in material objects to be justified only if it is possible to have at least one justified M[odal]P[roperties] belief” (Rea, 83). This is because 1. one must be able to say this is a material object, 2. that belief can only be justified by beliefs in certain properties that are essential to the object (essential in the philosophical sense), and 3. these kinds of beliefs are MP beliefs (Rea, 83-84).

There are a number of ways naturalists have tried to get around this problem, but ultimately they can, at most, only grant extrinsic modal properties. In order to grant intrinsic modal values, on naturalism, “(a) we must observe it, (b) we posit its existence to explain our observations, or (c)we discover that our theorizing is simplified or otherwise significantly pragmatically enhanced by supposing that it exists” (Rea, 104). But modal properties are not observable, so only (b) or (c) are possibilities.

The possible solution (b) generally points to tying modal properties in with Proper Function. Proper Function is, generally, the belief that certain things that occupy a certain region have an objective function that they are supposed to perform. But even granting that empirical techniques can somehow claim this about anything, Proper Function can only grant extrinsic modal properties (such as saying that cat-arranged things have the proper function of “operating” as cats). The problem remains.

Solution (c) presents a pragmatic argument. Now setting aside some of the blatant flaws with pragmatism in general (i.e. the absurdity that, on pragmatism, it follows that if there are no people, there is no truth), this pragmatic consideration within naturalism doesn’t help in discovering intrinsic modal properties as it is completely unclear as to what pragmatic value there is in considering intrinsic modal properties on naturalism. Not only that, but Rea presents another valuable argument: “If, for example, it cannot be a truth that a thing x has a property p unless it is somehow useful or convenient for human beings to believe that x has p, then it is hard to see how x could have p in a world that does not include human beings.” [As I mentioned.] “So pragmatic theories of truth seem to imply (perhaps absurdly) that every property is extrinsic [ed: in that properties are assigned pragmatically]. hence, they also imply that modal and sortal properties are extrinsic. Thus they are incompatible with R[eality about]M[aterial]O[bjects]” (Rea, 146).

The Discovery Problem thus eliminates the possible of RMO, ROM, and materialism from the naturalist ontology. But these are things that naturalists will be extremely reluctant to eliminate. Rea follows with a discussion of intuitionism–which is another way naturalists might salvage RMO from the implications of naturalism, but the problem with intuitionism is that it is a version of idealism which eliminates RMO to begin with. I’m not going to go into the details of Rea’s argument here, as to do so would take quite a bit of extra space and I don’t think it is all that relevant to the current discussion.

I find Rea’s method quite sound, and his reasoning is certainly solid. Whether or not his book is successful (as I think it is), it certainly is thought-provoking. I expect many a naturalist will be forced to reconsider his or her position and attempt many a rejoinder to the arguments contained in World Without Design. One such rejoinder will be discussed next.

A critique of Rea’s work can be found here. The author (Troy Cross) was quite fair in his evaluation of Rea’s work, but I think the conclusions he drew weren’t quite spot on. For example:

“Rea’s ‘charitable’ proposal on naturalism’s behalf [that of it being a research program], by contrast, is to be avoided at all costs… Rea’s argument is not of the form: there are material objects, therefore, naturalism is false.”

But it is in Cross’ accusing Rea of being unnecessarily “charitable” that he seems to ignore one of the central arguments of the first chapters, which is an argument against naturalism as Cross seems to want to take it [though as I discussed above I am not entirely sure of its success]. Not only that, but while he states specifically what Rea’s argument is not (and I agree with him), he seems to ignore that if Rea has succeeded in his actual argument, then while naturalism may not be untrue or false on an epistemological level, naturalists are forced into some uncomfortable positions. In fact, I don’t really think that Rea is anywhere trying to prove naturalism is false, but only that naturalism forces us to give up much on an ontological level and that some of these beliefs seem basic to naturalism itself. It is in this way that many of Cross’s critiques fail. He seems to miss the general point of Rea’s book, which may perhaps be summed up in Rea’s own words:

“I think it is important to acknowledge that the theses I have said naturalists must give up are theses that many philosophers, naturalists in particular, will be very reluctant to give up.”

and

“We are told that if only we look in the right places we will find everything we want: realism about material objects, realism about other minds, materialism for those who want it, and much more. But when all the shells have been turned over, we find that we have been duped, and nothing is there.” (Rea, 170)

Further, Cross makes a rather bold statement by asserting, “Perception is a science-approved basic source of justification, and on a suitably robust notion, perception delivers real material objects, not merely sense data or mind-dependent objects.” Despite these claims, he offers no evidence to support it. It seems he missed the section on pragmatism, or at least chose to ignore it. In what way does naturalism, with its “science-approved” methodology somehow grant itself the assumption that perception is not mind based? How does his claim rule out idealism? He truly fails in this regard, and he falls victim to his own presuppositions.

Naturalists cannot seem to view their own worldview objectively at all (see Quine’s quote, above). Material objects are simply assumed based on perception and it is similarly assumed that materialism is true. And then it follows from these two assumptions that the mind is at the least supervenient on the physical. But this is nothing other than a circular argument. If any one of these three assumptions fails, then the circle is broken. And I don’t see any reason that all of these assumptions won’t fail. Not only that, but a circular argument is  a simple logical fallacy.

What grounds do naturalists have to accept such a statement as Cross makes? The assumption that perception somehow proves material objects flies in the face of competing metaphysical approaches such as idealism and certainly begs the question against them. And because of this, such a statement is, if not false, at least lacking any kind of epistemic value. It’s nothing but an assumption with no grounds (other than perhaps pragmatism) for accepting it. And if one would like to argue for such a view on pragmatic grounds, the arguments presented by Rea against pragmatism apply.

Naturalists seem to make these kinds of statements all the time. Whatever they say they simply grant because of either pragmatic concerns or some kind of circular argument. There is no reason to accept either of these reasons.

So Cross seems to miss the mark in a number of ways. He is attempting to argue against a point Rea didn’t make. When he argues that Rea fails to give epistemic reasons that naturalism is false, he is arguing against a straw man. Rea isn’t trying to do so to begin with. Rather, he is arguing that if naturalism is true, it forces those who want to accept it to give up many of the things that they may wish to take as truths–those things shown above, namely, ROM, RMO, and materialism. Not only that, but Cross fails to make any kind of argument for a naturalism that escapes Rea’s casting of it as a “research program.” Cross instead states “[Rea] succeeds in aiding and motivating the construction of naturalistic theories.” The problem is that the construction of those theories hasn’t happened. The current naturalism is fully subject to the arguments presented in World Without Design, and the consequences of naturalism are hard to swallow.

I should note, in closing, that the arguments I make above against Cross (particularly my statement that he is making assumptions and/or begging the question for naturalism) might be leveled against my own view of theism. It should be noted, however, that Rea himself addresses these issues briefly. But there are other reasons that such accusations don’t have merit, for theism doesn’t presuppose such things as dualism. There is a huge amount of literature dedicated to the mind-body problem that is readily accessible. Further, claims that God is the basis for intrinsic modal properties and/or intrinsic human worth have also been addressed in many formats by theists. Certainly, theists may make claims that grant certain underlying beliefs, but those beliefs themselves are building blocks that theists at least have arguments that at the least warrant, if not justify those beliefs (I can once again refer to dualism as a prime example). Naturalists have no such warrant. It is simply assumed that scientism or empiricism is the correct method (or argued on the basis of pragmatism), and that somehow this serves as a defeater for idealism, various theistic views, or other explanatory positions. But, as can be seen in Rea’s book and our brief discussion, these claims only lead us to a rejection of those things which naturalists hold most dear: material objects and materialism itself.

Religious Experiences: Providing Warrant for Belief in God

Physicalism: Rejected on the Grounds of Unintelligibility

Physicalism is the view that everything is physical. Every thought, mental state, etc. we experience is reducible to physical explanations. It can be said, according to physicalism, that neurons firing or chemicals being released are an emotion or mental state.

I believe physicalism can be rejected on the grounds of unintelligibility. One reason for this is that physicalism forgets the idea of causation. It equates a cause with an entire process. One can agree that there are physical causes for a mental event, but does not have to accept that this means that a mental event itself is physical. An emotion is not a firing of a neuron or some amalgam of chemicals. Mental states are described from a first-person subjective viewpoint, and cannot be equated with the physical world, which is described in physical terms.

The most commonly used argument for physicalism is the “argument from causal closure”:

–”If an event e causes event e*, then there is no event e# such that e# is non-supervenient [edit: supervenient generally means dependent] on e and e# causes e*.” (Stanford Encyclopedia of Philosophy).

The problem with this view, of course, is that it can be countered by simply rejecting premise 2 “there is no event e# such that e# is non-supervenient on e and e# causes e*.” One can simply point out that it is possible for there to be an event e# to exist.

Further, what exactly does it mean to say that mental states are wholly physical? I believe that is ontologically untrue. One can simply examine one’s own thoughts and realize that, say, thinking about a pink elephant is not ontologically a pink elephant. Physicalists would have to try to describe this mental image wholly in physical terms, for that is all there is to the world according to their methodology. But it is then almost impossible to distinguish between the image of a pink elephant and the pink elephant itself. Try that thought experiment. Describe yourself “thinking about a pink elephant” in wholly physical terms. Do not slip into saying such words as “mental state”, “mental”, “thinking”, “I”, and the like. It may be possible, but it ends up being something utterly ridiculous which doesn’t seem to really describe the event (thinking about a pink elephant) at all. It describes the things that are causing one to think of a pink elephant.

Physicalism also leads inevitably to determinism. If all things are wholly physical, there cannot be any kind of freedom of the will. All things are determined by physical processes, meaning there is simply no individual to possess freedom.

Physicalism can be faulted for either not adequately explaining or completely rejecting: mental states, the will, individuals, liberetarian freedom, freedom of permission, freedom of personal integrity, and freedom of moral and rational responsibility.

What exactly does it mean, within physicalism, to have the “want to do something?” For example, I am moving my things from one room to another. I want to lift up and move my couch on my own, but I cannot. Physicalism does not seem to have an adequate explanation for this. Wanting to do something could be causally linked to certain parts of the brain showing activity, but it could not explain the desire itself.

What would it mean if, say, a scientist could monitor the brain and know every thing a person was thinking about? Imagine being able to do such a thing. Looking at a screen, one could see that a person could think about a “dog” and one would not actually know what that person is thinking. Or, perhaps the technology is such that the dog which the person was thinking of would be entirely described. It’s a black lab the person owned in his or her childhood, it has a scar on its nose from a fight with a cat, its fur has a bluish sheen in certain light, etc. It still does not mean that one could literally read this person’s mind. For the mental image of a black lab, down to the tiniest detail (i.e. fur length, etc.) will be different from one person to the next. Even if we could literally think of every detail, including the length of each individual hair on that lab, etc., the mental image we had would be different, for we all think of such details in different ways. Descriptions of colors, scents, sounds, etc. vary widely from person to person.

But then, what if we could project an image onto the screen of that dog, in every detail? Two things would prevent this from allowing an identical image: 1. any emotional attachment to the image, and 2. the subjective interpretation of sensory imagery.

Another way to try to explain this scenario into possibility for the physicalist would be to say that technology could allow us to transfer that image, with its emotion, etc. into someone else’s mind. But then, we still have problems. 1. Even if we could project the exact image, along with it’s emotional responses, into someone else’s brain, that person’s brain would still interpret that image for itself. It would be presented with certain emotional states, sensory details, etc., but it would be filtering all of those through its own system. 2. There’s no clear way to say that even if we could eliminate problem 1, the image would be exactly the same with both people.

Even if one could project all the emotion, history, details, and the like of an image from one person to the other, it would not be the same. Why not? Because of another problem with physicalism: emotional states are not the same. What one person experiences as pain can be entirely different for someone else. Let’s say that, sticking with the black lab, subject A has a positive experience of this animal. This brings with it the feeling of pleasure at recalling the image, and calmness related to feeling protected by the dog. When it is projected into the brain of subject B, these emotions may not be the same. For even if one could capture the intensity of these feelings, there’s no way to say that the conotations they’d carry would be the same. Subject B would have pleasure related to recalling the image projected into his or her brain, but this pleasure would have to be intepreted by Subject B before it was presented as an image. The pleasure could feel different from subject A to person B, despite the exact same physical processes involved.

But what if we could project literally every aspect of this image into someone else’s mind (from person A to B)? What if we could somehow get past the interpretation problem? Would this then prove physicalism has weight? I don’t believe so. The problem here is threefold: 1. The problem of “self” in regard to the image. If the image were projected in such a way from person A to B, would it then be person B’s thought/image or would it still be person A’s, just projected into another brain (or mind)? For physicalism to be true, the image would have to be person B’s and identical to person A’s, but it seems like this is not the case, both by the nature of the whole experiment and by the fact that the image exists within person A’s brain originally. Not only that, but 2. it ignores the fact that there is such a thing as the image itself. Even if 1. were not a defeater of physicalism in this case, it seems to be defeated by the fact that the image is itself not made itself all the factors that go into making the image, but is simply an image. The image itself is different from the causation. There is not a black lab within someone’s brain. There is the image of this black lab within their brain. The fact that it must be discussed in such terms goes against physicalism. Cause is not equal to effect. 3. If this entire scenario were about an image that was imagined in person A’s head, rather than a real black lab he or she owned, it runs into a whole host of other problems. What does it mean to have something that doesn’t actually exist, existing in two people’s brain/minds? How is it that physical explanations give rise to a non-physical thing (something that is imagined does not exist physically, so it does not have physical space, qualities, etc., and cannot therefore be reduced to physical qualities, as it does not posess any)?

The point of this scenario is to point out that physicalism discounts some of the most self-evident qualia we experience. Physicalism cannot account for such differences in pain, pleasure, and other feelings or emotional states. It cannot account for the differences in experience when the physical causation is the same.

Point 3. has in it yet another blow against physicalism. What of imagined things? It seems possible that we could physically explain how we bring forth the image of something that is imagined (such as a flying pig), but that does not explain in physical terms what exactly that imagined thing is. What is it, in terms of physicalism? It is not real or physical, so how can it be reduced to something physical? And we certainly cannot say the image does not exist, because anyone with an imagination can think of a flying pig! But even if we were to assign it physical properties (i.e., wings, pigs feet, curly tail, etc.), it would not actually possess any of these. It is something that simply does not exist physically, and it would beg the question to assign it physical properties.

Ontologically speaking, physicalism seems shot full of holes. It can be simple to talk about all mental states, images, and the like as if they were merely physical, but in the real world, does it really mean anything to say that? It is evident from one’s own experience that one can think in terms of self, in terms of intentionality,  and in terms that defy physical explanation. What does it show to say that such things don’t actually exist? It makes our personal experiences meaningless.

It is unintelligible to embrace physicalism, for it means nothing to say that our “self” is not a “self” but a mixture of physical explanations. It means nothing to say that our emotions don’t exist except in physical terms. It means nothing to say that the mind is not a “mind” but a physically reducible thing. It means nothing to say that imagined things don’t exist (they exist within the brain [or mind] of anyone with an imagination), and it begs the question to say that they possess physical properties.

Physicalism, at best, can serve only as a causal explanation of mind states, mental images, and the like. Yet the thesis itself claims to have superior explanatory power in that it can explain everything (via physical means). Finally, physicalism has inadequate explations for, or outright rejects, things that are evident simply through introspection (imaginary objects, the concept of “self,” etc.). Its claims about such things are either meaningless or unintelligible. I therefore reject it on the grounds of unintelligibility.
