MercatorNet: Is “Yuck!” a good enough reason?

It is my grave duty to inform you that the same is true of the discipline of ethics, where the most reasoned and convincing arguments nevertheless rest upon a set of basic assumptions which we simply must accept or deny. Those who best represent traditional ethics exist in a kind of parallel universe to most modern academic ethicists, and, it seems, never the twain shall meet.
Hence, such philosophers as the renowned and infamous Peter Singer can freely condemn the irrationality of moral intuition or “the yuck factor”, thereby defending in principle such remaining taboos as bestiality and incest.
