For several decades Freud's reputation has been steadily going downhill. One reason surely has been the realization by leading feminists that Freud never rose above Victorian male chauvinism, but the main reason is much stronger.

On matters for which he is given the most credit, such as the influence of repressed memories on behavior, Freud took over a commonly accepted opinion. You'll find long discussions of unconscious causes of psychosomatic ills in William James Principles of Psychology, published ten years before Freud began to invent his theories. It is where Freud departed from his colleagues that he should be judged, and it is precisely these departures that are coming to be seen, as Karl Popper and Peter Medawar have long insisted, as little more than colorful mythology projected by a neurotic genius. Even Freud's theory of dreams is now under fire, as recent research suggests that dreams may be mostly random by-products of the brain's process of clearing its circuits and that trying to recall dreams may actually harm a patient.
In a chapter of my Mathematical Carnival I tell of Freud's strange and passionate friendship with one of the giants of German crackpottery. He was a Berlin nose-and-throat doctor named Wilhelm Fliess--two years younger than Freud, handsome, charming, conceited, paranoid (he later thought Freud was trying to kill him), and utterly irresponsible. It is hard to believe, but for more than ten years he was Freud's most intimate confidant.
Fliess suffered from two major obsessions. He believed that all living processes conform to two cycles: a male cycle of 23 days, and a female cycle of 28 days. The theory became known as biorhythm, and later his
