On the question of morality, you again attempt an answer: “My answer is the same as it was all along: Our morality evolved.” There are two points to be made about this reply. The first concerns evolved morality and the future, and is a variation on my previous questions. If our morality evolved, then that means our morality changes. If evolution isn’t done yet (and why should it be?), then that means our morality is involved in this on-going flux as well. And that means that everything we consider to be “moral” is really up for grabs. Our “vague yet grand conception of human rights” might flat disappear just like our gills did.

Douglas Wilson, from a debate with Christopher Hitchens.

I am struck by Hitchens’ inability (or refusal) to answer Wilson’s most basic question.
