Disgust is a charged emotion since it has strong moral implications (see the work by Jonathan Haidt and more recently Simone Schnall). A better understanding of what it is from a historical perspective is urgently needed. And this book, extraordinary in many respects, delivers it. Argues that the history of aesthetics can be (best?) understood from the perspective of what has been avoided. Surprisingly, this is not so much the ugly as it is whatever provokes disgust (although the two may overlap). The readings of Nietzsche, Freud, and Kafka are remarkable and quite original.
