Timothy Leary's passion affected an entire culture and influenced modern world history. Flashbacks, Leary's own account of his career as "an accomplished clinical psychologist at Harvard University, a dabbler in Eastern mysticism, a fugitive and convict, a stand-up comedian and actor, a writer and software designer and exponent of cybernetics" - (The New York Times), is the only book written by him that directly addresses the issues, people, and history of his personal awakening and crusade.
