Harold Blum, a past Editor-in-Chief of the Journal of the American Psychoanalytic Association and author of more than 170 psychoanalytic papers and several books, posted this article on the website of the American Psychoanalytic Association:
Freud revolutionized the understanding and treatment of mental disorders. He created the psychoanalytic theory of personality. But beyond this, he profoundly changed our understanding of humanity, thought and culture. Freud, like Darwin, disturbed the sleep of the world by revealing hitherto unpalatable, but fundamental, truths about human nature.
