Drawing on research in psychology and evolutionary biology, Rachel Herz presents fascinating and informative insights in her book That's Disgusting. While most of us know that disgust originated to prevent people from eating poisonous food, making it a survivalist emotion, it is in fact very complex, highly individual, and shaped by the culture we grew up in. And unlike other emotions disgust is not innate, but an instinct that has to be learned.
Starting out with the most obvious topics - food as source of disgust - Rachel leads the reader down some unexpected paths. Disease, pornography, cannibalism, humor. All of these can be perceived as disgusting, while some may, oddly enough, even turn out to be fun and entertaining (unless you dislike stand-up comedians making jokes about bodily functions, that is). Especially the chapter on moral disgust intrigued me. Influenced by culture, it evokes the same emotion as physical disgust, yet it is clearly different.
If you're interested in the topic, this book is definitely a must-read!
In short: A truly absorbing and well researched book on the mysteries of repulsion!
