Last week Viewpoint discussed the book by philosopher Victor Reppert titled C.S. Lewis's Dangerous Idea. Reppert examines the corrosive effect that metaphysical naturalism, if true, has on the status of Reason. Reppert's basic argument is an elaboration of an argument employed by C.S.Lewis, but Reppert expands it and addresses several objections raised by critics.
His contention is that if matter, energy, and physical forces like gravity are all there is then everything is ultimately reducible to material, non-rational particles. If so, our beliefs are just brain states that can be completely explained in terms of non-rational physical forces. But any belief that is fully explicable in terms of non-rational causes cannot itself be rationally grounded. Therefore, if materialism is true, none of our beliefs are rationally grounded, Reason itself is a non-rational illusion, and both truth and the reliability of scientific invetsigation are chimerical. Thus the materialist has no rational grounds for believing that materialism is true or that anything is true.
Whatever the eventual verdict on this argument and its several derivatives is, one of the things the author does which is hard to gainsay is show that the atheists' claim to intellectual superiority based upon the rationality of their beliefs is something of a self-delusion. It intimidates the unsophisticated and unsuspecting perhaps, like suddenly encountering a bloated puffer fish, but there's nothing there to be particularly fearful of.
Reppert quotes two well-known intellectuals, one a leading materialist scientist and the other a philosopher, who inadvertantly reveal that whatever role reason plays in their professional lives, it has little to do with their ultimate commitments and that some of Reason's most eminent proponents are perfectly willing to abandon it when it suits their purpose. The first passage is from Richard Lewontin:
This is an extraordinary expression of dogmatic faith in naturalism, and it's not just non-rational, it's anti-rational. To see how, Reppert asks us to imagine the reaction of a materialist to a similar claim made by a Biblical theist:
Any Christian who wrote something like this would be laughed to scorn by skeptics, including, no doubt, Lewontin himself, yet a scientist of his stature writes almost exactly this, and his colleagues merely nod sagely and think nothing of it.
The second quote is from philosopher Thomas Nagel and his book The Last Word:
And Freudians accuse believers of engaging in irrational wish-fulfillment. Nagel's atheism is based upon a hope that there is no God, which is itself based upon a subjective preference for a Godless universe. The point here is that neither Lewontin nor Nagel is ultimately basing his anti-theism on anything rational. Even if the evidence went against them they would not yield in their adamantine refusal to accept the existence of God. Their ultimate commitments are founded primarily upon an aesthetic predilection for one kind of reality as opposed to another. The much vaunted role of Reason in the rejection by atheists of belief in God is shown, in these two men at least, to be quite irrelevant.
