Definition of "Beat Generation" offered to Random House publishers in 1959, after being asked him if there was anything he'd like to add to the definition they were preparing for the American College Dictionary: "Certain members of the generation that came of age after World War II who affect detachment from moral and social forms and responsibilities, supposedly the result of disillusionment. Coined by Jack Kerouac." The Random House definition eventually published read: "members of the generation that came of age after World War II who, supposedly as a result of disillusionment stemming from the Cold War, espoused forms of mysticism and the relaxation of social and sexual inhibitions."
