From Timothy Leary's 1983 autobiography, Flashbacks (via Wikipedia): "Turn on" meant go within to activate your neural and genetic equipment. Become sensitive to the many and various levels of consciousness and the specific triggers engaging them. Drugs were one way to accomplish this end. "Tune in" meant interact harmoniously with the world around you—externalize, materialize, express your new internal perspectives. "Drop out" suggested an active, selective, graceful process of detachment from involuntary or unconscious commitments. "Drop Out" meant self-reliance, a discovery of one's singularity, a commitment to mobility, choice, and change. Unhappily, my explanations of this sequence of personal development are often misinterpreted to mean "Get stoned and abandon all constructive activity"
