Dr Sigmund Freud has long been misunderstood as a nutcase or even a pervert for his ideas re: psychoanalysis, and his theories on "eros" and "thanatos". However, I have just read his five lectures on psychoanalysis, and I have found the scientific clarity with which he explained and conveyed his ideas to an audience completely unacquainted with such revolutionary ideas, mind blowing to say the least. While inherently difficult to comprehend, the sheer logic is utterly persuasive. In fact, Dr Freud is not some social scientist dreaming up some crazy psychological theory but a medical doctor who approached the problems of hysteria from the neurological viewpoint! Taking this background into account, I think his ideas must be given due credit and plausibility.
However, I must say that the origins of hysteria as a disease have not been beyond reproach. In fact, hysteria means "wandering womb" as those afflicted were often of the gentler gender; so the predominantly male doctors of the time viewed it as a female ailment, akin to something gynaecological in origin. They kind of thought the womb would wander around the body causing all kinds of symptoms in a typically fickle female manner. This is of course laughable in retrospect - we all know very well in this modern day and age that the female mind is perfectly capable of all that fickleness and much much more, without the help of the uterus.
