Disgust and Moral Taboos

Disgust is not a pleasant subject. It is perhaps partly for this reason that it has not been much discussed in philosophical literature, or, indeed anywhere else. Disgust has considerable moral significance however, and appreciating its significance will illuminate the present state of our morality. One may be led to this view by reflecting on several recent works on pollution. The pollution in question, of course, is not of the air, soil, or water, but that of people who have violated moral taboos of their society'.
