"Underlying the crisis in psychoanalysis is an existential or social ambiguity from which Freud himself was not free. Esoterically, Freud knew that what he had in hand was either nothing at all or a revolution in human thought.

"Exoterically, he launched the psychoanalytical movement as a method of therapy controlled by professional adepts and available only to a select and wealthy few, individuals moreover whose usefulness to society was already impaired by an "abnormal" degree of frustration or mental disorder.

"We, however, are concerned with reshaping psychoanalysis into a wider general theory of human nature, culture, and history, to be appropriated by the consciousness of mankind as a whole as a new stage in the historical process of man's coming to know himself.

"The entry into Freud cannot avoid being a plunge into a strange world and a strange language world of sick men, a diagnostic language of formidable technicality. But this strange world is the world we all of us actually live in."
