Ethical Individualism and the Natural Law

"Generic qualities" are qualities typical of a kind because of the nature of that kind. It is commonly thought that generic qualities are morally irrelevant. For instance, the fact that human beings have a natural tendency to be thus-and-such is not relevant to moral acts involving a particular human being; what matters, rather, are the qualities of that individual. I argue that generic qualities are relevant in certain instances. First, we need to believe that this is so in order to be morally competent. Second, there is no other way to account for the rationality of the universal response to Oedipus the King .
