It's an interesting book. He talks about savages, who are the peoples of the world who are are, basically, aboriginal and not inheritantly Christian. The Aboriginies of Australia, the Native Americans of North America, etc. He compares these people's clan system (totem) and their taboo's to the thinking (?) of neurotics (neurosis being a perfectly valid diagnoses back then).
I don't think Freud had the vaguest idea about these native peoples and was extremely general in trying to figure out why they think and have the beliefs they do.
Nevertheless, the book was thought provoking.
I like how Freud linked everything back to sex. He must've been quite the pervert. I also learned a new word for taking a piss: micturate.
