"The book combines history, sociology, political science and prophecy. The first two-thirds of the book features a critique of modern American society and its consumerism and conformity. In that, it was far from unique. But Reich also wrote about three categories of consciousness. Consciousness I was the traditional self-reliant outlook of early America. It was replaced by the New Deal conformism of organizational society, Consciousness II. … It was Consciousness III, the counterculture of '60s youth, that attracted the most controversy. Reviews were mixed but mostly negative. For some reviewers, when it came to Consciousness III, Reich was politically naive and excessively romantic. He celebrated the hippie lifestyle and the use of psychedelic drugs. Marijuana "is a truth serum that repels false consciousness," Reich wrote. Reich was praised for capturing the spirit of the counterculture and struck a chord with parents by making it understandable and non-threatening. The book was written "with the rigour of an intellectual and the enthusiasm of a teenager," wrote law professor Rodger Citron in a 2007 biographical essay on Reich."
