These lectures were given by Freud at the University of Vienna during the winter terms of 1915-1916 and 1916-1917. They were originally delivered extemporaneously, then written down by Freud immediately afterward. Though a modern reader is not likely blithely accept theories such as 'Penis Envy' and the 'Oedipus Complex,' these lectures remain an excellent introduction to Freud's thought, delivered by the man himself.
Here are some representative quotations from the book:
"(P)sycho-analysis is a procedure for the medical treatment of neurotic patients."
"(Psycho-analysis asserts) that instinctual impulses which can only be described as sexual ... play an extremely large and never hitherto appreciated part in the causation of nervous and mental diseases. It asserts further that these same sexual impulses also make contributions that must not be underestimated to the highest cultural, artistic and social creations of the human spirit."
"What instigates a dream is a wish, and the fulfillment of that wish is the content of the dream---this is one of the chief characteristics of dreams."
"The very great majority of symbols in dreams are sexual symbols."
"I refer you to ... C.G. Jung, at a time when he was merely a psycho-analyst and had not yet aspired to be a prophet..."
"(After Copernicus and Darwin) human megalomania will have suffered its third and most wounding blow from the psychological research which seeks to prove to the ego that it is not even master in its own house, but must content itself with scanty information of what is going on unconsciously in its mind."
"(Psycho-analysis) can be applied to the history of civilization, to the science of religion and to mythology, no less than to the theory of the neuroses, without doing violence to its essential nature. What is aims at and achieves is nothing other than the uncovering of what is unconscious in mental life."
