Thomas Szasz's classic book revolutionised thinking throughout the world about the nature of the psychiatric profession and the moral implications of its practices. By diagnosing behaviour problems as 'mental illness', psychiatry, Szasz argues, absolves the individual of responsibility for his actions, placing blame instead on the illness. In "The Myth of Mental Illness", he attacks Freudian psychology as a dangerous pseudo-science and critiques the overreach of psychology into all aspects of modern life.
