"This book finally gives us the concepts to think or say why assholes disturb us so, and explains why such people seem part of the human social condition, especially in an age of raging narcissism and unbridled capitalism. These concepts are also practically useful, as understanding the asshole we are stuck with helps us think constructively about how to handle problems he (and they are mostly all men) presents. We get a better sense of when the asshole is best resisted, and when he is best ignored—a better sense of what is, and what is not, worth fighting for."
