The problem, however, is that I have yet to meet anyone, materialist or otherwise, who was able to dispense with value judgments. On the contrary, the literature of materialism is peculiarly marked by its wholesale profusion of denunciations of all sorts. Starting with Marx and Nietzsche, materialists have never been able to refrain from passing continuous moral judgment on all and sundry, which their whole philosophy might be expected to discourage them from doing.

Imagine a person who . . . argues ‘no air exists’ but continues to breathe air while he argues. Now intellectually, atheists continue to breathe — they continue to use reason and draw scientific conclusions [which assumes an orderly universe], to make moral judgments [which assumes absolute values] — but the atheistic view of things would in theory make such ‘breathing’ impossible. They are breathing God’s air all the time they are arguing against him.
