I must admit that I was under the wrong impression about the meaning behind the slogan coined by Timothy Leary. I do not advocate his approach to psychedelic drugs, because it was often reckless. Nonetheless, here is his explanation of ‘Turn on, Tune in, Drop out’.
Leary explained in his 1983 autobiography Flashbacks: “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 that engage 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 elective, 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 were often misinterpreted to mean ‘Get stoned and abandon all constructive activity.”
