What is the name of the book Jenny is reading?

M: Hey, Jenny!
F: Oh, Johnny! You scared me.
M; You seemed today absorbed in this book. What is the name of it?
F: The Interpretation of Dreams.
M: You’re reading Freud. Can you understand the book? Or do you agree with the opinions in the book?
F: Well, as a matter of fact, it is rather difficult for me. It is part dream analysis, part autobiography, part theory of the mind, and part history of contemporary Vienna. The principle that underlay this book was that mental experiences and entities, like physical ones, are part of nature.
M: Sounds complicated.
F: Ah, that means that Freud could admit no mere accidents in mental procedures.
M: That is even more confusing.
F: Well, he thought that even nonsense, the most casual slip of the tongue, the most fantastic dream, must have a meaning.
M: Then what?
F: Then he applied this principle lo treat his patients, which is called psychoanalytic therapy. When treating his patients, he would be a largely silent listener and encouraged the patients to say whatever comes to mind, no matter how foolish, repetitive or outrageous. He occasionally intervened to what the patient is struggling to say.
M: I think this therapy is quite popular in modern practice.
F: Yes, although the effect of this analysis still remains a question. Do you know about his fundamental idea?
M: Just some vague ideas. Like that all humans are born with strong sexual desires and aggressiveness that fight against your intentions to suppress them; that erotic desire starts as early as in infancy.
F: You are right. And in many people’s eyes, this is nothing less than obscene. That is why there are never neutrals in the Freud wars. A psychoanalyst may regard Freud as a cultural hero, while another critic may devote his days to exposing Freud as a charlatan.
