Nietzsche realized that the Enlightenment project to reconstruct morality from rational principles simply retained the character of Christian ethics without providing the foundational authority of the latter. Dispensing with his fantasy of the Übermensch, we are left with his dark diagnosis. To paraphrase the Scottish philosopher Alasdair MacIntyre, our moral vocabulary has lost the contexts from which its significance derived, and no amount of Dawkins-style hand-waving about altruistic genes will make the problem go away. (Indeed, the ridiculous belief that our genes determine everything about human behavior and culture is a symptom of this very problem.)
