Evolution and the possibility of ethics: A Humanist reply to Pope John Paul II and Immanuel Kant

If evolution has equipped us for a xenophobic morality, denying that fact by postulating for humanity a transcendent essence is, in my view, the intellectual equivalent of an ostrich burying its head in the sand to escape danger. That we are unhappy with the logic of evolution says nothing about the validity of that logic. If natural xenophobes is what we are then the sooner we accept it and learn to deal with it the better for everyone.
