The final part of a debate between theologian Wilson and atheist polemicist Hitchens.  This is Wilson speaking:

This relates to the second point, which concerns evolved morality and the past. When dealing with people whose moral judgments have differed from yours, do you regard them as “immoral” or as “less evolved?” The rhetoric of your book, your tone in these exchanges, and your recent dancing on the grave of the late Jerry Falwell would all seem to indicate the former. In your choice of words, the people you denounce are to be blamed. The word fulminations comes to mind. You write like a witty but acerbic tenth-century archbishop with a bad case of the gout. But this is truly an odd thing to do if “morality” is a simple derivative of evolution. Are you filled with fierce indignation that the koala bear hasn’t evolved ears that stick flat to the side of his head like they are supposed to? Are you wroth over the fact that clams don’t have legs yet? When you notice that the bears at the zoo continue to suck on their paws, do you stop to remonstrate with them?

Your notion of morality, and the evolution it rode in on, can only concern itself with what is. But morality as Christians understand it, and the kind you surreptitiously draw upon, is concerned with ought. David Hume showed us that we cannot successfully derive ought from is. Have you discovered the error in his reasoning? It is clear from how you defend your ideas of “morality” that you have not done so. You are a gifted writer, and you have a flair for polemical voltage. But strip it all away, and what do you have underneath? You believe yourself to live in a universe where there is no such thing as any fixed ought or ought not. But God has gifted you with a remarkable ability to denounce what ought not to be. And so, because you reject him, you have great sermons but no way of ever coming up with a text. When people start to notice the absence of texts, the absence of warrant, the absence of reasons, you adjust and compensate with rhetorical embellishment and empurpled prose. You are like the minister in the story who wrote in the margin of his notes, “Argument weak. Shout here.”
