How can someone who says, almost proudly, that ethics is an illusion of the genes mesh with Christianity, a religion that puts obedience to God’s word and will right at the heart? In fact, it is not as difficult as it seems, so long as you remember that I am offering a naturalistic account of ethics, and Christianity is a supernatural religion.
I am saying that if you ask, “Take God out of the equation and can you still get ethics?” my answer is, “Yes, you can, if you are talking about normative ethics, but when you enter the metaethical realm you find that it is all biology and psychology, with no further meaning.
The thought that there is something more—the thought needed to make normative ethics function—is an illusion.”
