It is impossible to overstate the cultural significance of the four men described in Don Lattin's The Harvard Psychedelic Club. Huston Smith, tirelessly working to promote cross-cultural religious and spiritual tolerance. Richard Alpert, a.k.a. Ram Dass, inspiring generations with his mantra, "be here now." Andrew Weil, undisputed leader of the holistic medicine revolution. And, of course, Timothy Leary, the charismatic, rebellious counter-culture icon and LSD guru. Journalist Don Lattin provides the funny, moving inside story of the "Cambridge Quartet," who crossed paths with the infamous Harvard Psilocybin Project in the early 60's, and went on to pioneer the Mind/Body/Spirit movement that would popularize yoga, vegetarianism, and Eastern mysticism in the Western world.
