Freud influenced social thought on at least three separate levels. First, and probably of least enduring significance, was through his socially focused books themselves, works like The Future of an Illusion and Totem and Taboo, which—apart from Civilization and Its Discontents, now ensconced in the liberal arts canon—are rarely read anymore and feature farfetched notions like "the primal parricide." Freud himself shared this assessment, it seems. Roazen quotes Freud as saying that Civilization and Its Discontents "strikes me…as quite superfluous in contrast to earlier works which always sprang from some inner necessity. But…one cannot smoke and play cards all day" (p. 103). And of The Future of an Illusion he was even more blunt: "This is my worst book! It’s the book of an old man" (p. 103).
