William Miller embarks on an alluring journey into the world of disgust, showing how it brings order and meaning to our lives even as it horrifies and revolts us. Our notion of the self, intimately dependent as it is on our response to the excretions and secretions of our bodies, depends on it. Cultural identities have frequent recourse to its boundary-policing powers. Love depends on overcoming it, while the pleasure of sex comes in large measure from the titillating violation of disgust prohibitions. Imagine aesthetics without disgust for tastelessness and vulgarity; imagine morality without disgust for evil, hypocrisy, stupidity, and cruelty.
