The term "narcissism" is continuously mentioned in the media, the subject of millions of online queries, and the center of political debates. But what does this term really mean? One of the most acclaimed specialists on the issue breaks down the generally misused concept and delves into the most recent psychological and sociological research on the phenomenon. Rather than pathologizing the associated behaviors, the author not only reveals to us that narcissism occurs in a wide spectrum of contexts, but that almost everyone displays narcissistic tendencies. Based on real cases, this book includes tools and suggestions to work on toxic behavior patterns both towards others and in oneself.
