The rest of the book proceeds largely as a novel of ideas, mostly involving Frazier, a smug, talkative, and colorful character, guiding his new visitors around Walden Two and proudly explaining its socio-politico-economic structures and collectivist achievements. A wide range of intellectual topics such as behavioral modification, political ethics, educational philosophy, sexual equality (specifically, advocacy for women in the workforce), the common good, historiography, freedom and free will, the dilemma of determinism, fascism, American democracy, and Soviet communism are discussed and often debated among the self-satisfied Frazier, the skeptical and doubting Castle, and the quietly intrigued Burris.
