(A more in-depth convo with the Vice-President of the Cornell University Atheist Society)
Let’s consider a basic question: Why does the natural world make any sense to begin with? Albert Einstein once remarked that the most incomprehensible thing about the universe is that it is comprehensible. Why should we be able to grasp the beauty, elegance, and complexity of our universe?
Einstein understood a basic truth about science, namely, that it relies upon certain philosophical assumptions about the natural world. These assumptions include the existence of an external world that is orderly and rational, and the trustworthiness of our minds to grasp that world. Science cannot proceed apart from these assumptions, even though they cannot be independently proven. Oxford professor John C. Lennox asks a penetrating question, “At the heart of all science lies the conviction that the universe is orderly. Without this deep conviction science would not be possible. So we are entitled to ask: Where does the conviction come from?”” Why is the world orderly? And why do our minds comprehend this order?
Toward the end of The God Delusion, Dawkins admits that since we are the product of natural selection, our senses cannot be fully trusted. After all, according to Darwinian evolution, our senses have been formed to aid survival, not necessarily to deliver true belief. Since a human being has been cobbled together through the blind process of natural selection acting on random mutation, says Dawkins, it’s unlikely that our views of the world are completely true. Outspoken philosopher of neuro-science Patricia Churchland agrees:
The principle chore of brains is to get the body parts where they should be in order that the organism may survive. Improvements in sensorimotor control confer an evolutionary advantage: a fancier style of representing [the world] is advantageous so long as it… enhances the organism’s chances for survival. Truth, whatever that is, takes the hindmost.
Dawkins is on the right track to suggest that naturalism should lead people to be skeptical about trusting their senses. Dawkins just doesn’t take his skepticism far enough. In Miracles, C. S. Lewis points out that knowledge depends upon the reliability of our mental faculties. If human reasoning is not trustworthy, then no scientific conclusions can be considered true or false. In fact, we couldn’t have any knowledge about the world, period. Our senses must be reliable to acquire knowledge of the world, and our reasoning faculties must be reliable to process the acquired knowledge. But this raises a particularly thorny dilemma for atheism. If the mind has developed through the blind, irrational, and material process of Darwinian evolution, then why should we trust it at all? Why should we believe that the human brain—the outcome of an accidental process—actually puts us in touch with reality? Science cannot be used as an answer to this question, because science itself relies upon these very assumptions.
Even Charles Darwin was aware of this problem: “The horrid doubt always arises whether the convictions of man’s mind, which has developed from the mind of the lower animals, are of any value or at all trustworthy. Would anyone trust the conviction of a monkey’s mind, if there are any convictions in such a mind?” If Darwinian evolution is true, we should distrust the cognitive faculties that make science possible.

Even Darwin had some misgivings about the reliability of human beliefs. He wrote, “With me the horrid doubt always arises whether the convictions of man’s mind, which has been developed from the mind of lower animals, are of any value or at all trustworthy. Would any one trust in the convictions of a monkey’s mind, if there are any convictions in such a mind?”
Given unguided evolution, “Darwin’s Doubt” is a reasonable one. Even given unguided or blind evolution, it’s difficult to say how probable it is that creatures—even creatures like us—would ever develop true beliefs. In other words, given the blindness of evolution, and that its ultimate “goal” is merely the survival of the organism (or simply the propagation of its genetic code), a good case can be made that atheists find themselves in a situation very similar to Hume’s.
The Nobel Laureate and physicist Eugene Wigner echoed this sentiment: “Certainly it is hard to believe that our reasoning power was brought, by Darwin’s process of natural selection, to the perfection which it seems to possess.” That is, atheists have a reason to doubt whether evolution would result in cognitive faculties that produce mostly true beliefs. And if so, then they have reason to withhold judgment on the reliability of their cognitive faculties. Like before, as in the case of Humean agnostics, this ignorance would, if atheists are consistent, spread to all of their other beliefs, including atheism and evolution. That is, because there’s no telling whether unguided evolution would fashion our cognitive faculties to produce mostly true beliefs, atheists who believe the standard evolutionary story must reserve judgment about whether any of their beliefs produced by these faculties are true. This includes the belief in the evolutionary story. Believing in unguided evolution comes built in with its very own reason not to believe it.
This will be an unwelcome surprise for atheists. To make things worse, this news comes after the heady intellectual satisfaction that Dawkins claims evolution provided for thoughtful unbelievers. The very story that promised to save atheists from Hume’s agnostic predicament has the same depressing ending.
It’s obviously difficult for us to imagine what the world would be like in such a case where we have the beliefs that we do and yet very few of them are true. This is, in part, because we strongly believe that our beliefs are true (presumably not all of them are, since to err is human—if we knew which of our beliefs were false, they would no longer be our beliefs).
Suppose you’re not convinced that we could survive without reliable belief-forming capabilities, without mostly true beliefs. Then, according to Plantinga, you have all the fixins for a nice argument in favor of God’s existence For perhaps you also think that—given evolution plus atheism—the probability is pretty low that we’d have faculties that produced mostly true beliefs. In other words, your view isn’t “who knows?” On the contrary, you think it’s unlikely that blind evolution has the skill set for manufacturing reliable cognitive mechanisms. And perhaps, like most of us, you think that we actually have reliable cognitive faculties and so actually have mostly true beliefs. If so, then you would be reasonable to conclude that atheism is pretty unlikely. Your argument, then, would go something like this: if atheism is true, then it’s unlikely that most of our beliefs are true; but most of our beliefs are true, therefore atheism is probably false.
Notice something else. The atheist naturally thinks that our belief in God is false. That’s just what atheists do. Nevertheless, most human beings have believed in a god of some sort, or at least in a supernatural realm. But suppose, for argument’s sake, that this widespread belief really is false, and that it merely provides survival benefits for humans, a coping mechanism of sorts. If so, then we would have additional evidence—on the atheist’s own terms—that evolution is more interested in useful beliefs than in true ones. Or, alternatively, if evolution really is concerned with true beliefs, then maybe the widespread belief in God would be a kind of “evolutionary” evidence for his existence.
You’ve got to wonder.

My argument against God was that the universe seemed so cruel and unjust. But how had I got this idea of just and unjust? A man does not call a line crooked unless he has some idea of a straight line. What was I comparing this universe with when I called it unjust? If the whole show was bad and senseless from A to Z, so to speak, why did I, who was supposed to be part of the show, find myself in such violent reaction against it? A man feels wet when he falls into water, because man is not a water animal: a fish would not feel wet. Of course I could have given up my idea of justice by saying it was nothing but a private idea of my own. But if I did that, then my argument against God collapsed too–for the argument depended on saying that the world was really unjust, not simply that it did not happen to please my fancies. Thus in the very act of trying to prove that God did not exist–in other words, that the whole of reality was senseless -I found I was forced to assume that one part of reality–namely my idea of justice–was full of sense. Consequently atheism turns out to be too simple. If the whole universe has no meaning, we should never have found out that it has no meaning: just as, if there were no light in the universe and therefore no creatures with eyes, we should never know it was dark. Dark would be a word without meaning.
