Susan it's been 40 years since I read that bestseller. Here's an overview from Wiki
"The book's argument rests on three separate types of consciousness. "Consciousness I" applies to the world-view of rural farmers and small businesspeople that arose and was dominant in 19th century America. "Consciousness II" represents a viewpoint of "an organizational society", featuring meritocracy and improvement through various large institutions; it dominated the New Deal, World War II and 1950s generations. "Consciousness III" represents the worldview of the 1960s counterculture, focusing on personal freedom, egalitarianism, and recreational drugs.
The book mixed sociological analysis with panegyrics to rock music, cannabis, and blue jeans, arguing that these fashions embodied a fundamental shift in world view.
The book was a best-seller in 1970 and 1971, and topped the New York Times Best Seller list on December 27, 1970 and other weeks."
