On the question of prevalence, this first DSM entry was cagey: “This disorder appears to be more common recently than in the past, but this may be due only to more professional interest in it.” But behind that neat list of narcissistic traits, within psychology’s ever-expanding and dividing fields and schools, the debates continued: How much self-regard is normal, and how much unhealthy or even evil? When someone is acting like a six-year-old, should you empathize with their view of reality or try to correct it? If someone doesn’t want to talk to you or fall in love with you, when is that because he is fundamentally an asshole? If someone turns suddenly away from treatment, or from a relationship, does that mean she is incapable of love? Are there really people who have no empathy? Can you help someone learn to love? And is this thing called narcissism something some people are, or something they do? These are questions you can ask forever, not only if you are a psychologist, but if you find yourself loving someone who turns away.
