By Simon Baron-Cohen
The book takes a closer look at empathy. Especially interesting is the term 0-empathy, including 0-empathy negative and 0-empathy positive. Referring to 0-empathy negative the focus is on borderline, psychopathy and narcissism. With 0-empathy positive the focus is on Asperger syndrome. Heredity and environment are discussed in relation to all the conditions.
It is a good and rewarding book spiced with cases.
