In the soul of a psychopath. Journey to a world without pity, conscience and feelings

For the first time in history, Pyotr Borisovich Gannushkin dared to study and classify the frightening world of people who lack the ability to feel - psychopaths. The proposed book by the outstanding Russian psychiatrist P. B. Gannushkin was the result of almost thirty years of research activity by the author. For the first time, clear clinical criteria for delimiting constitutional psychopathy were given, and the three features that define them, which have retained their significance to this day, were substantiated. The work examines in detail the types, laws, formulas for the development of psychopathy, gives the author's classification of psychopathy, and most importantly, presents hundreds of real and often tragic stories of people who are deprived of the ability to feel.
