Timothy Leary, the visionary Harvard psychologist who became a guru of the 60's counterculture, re-emerged at the end of his life as an spokesperson on cyberspace and cybersex. Timothy Leary, in his 37 books and monographs, 250 articles, and more than 100 printed interviews published since the early 1950s has helped define the Humanistic Revolution which had a huge impact on world culture. His books and papers as a psychologist in the 1950s helped launch the emerging "Humanistic Psychology" movement with an emphasis on interpersonal relationships, multilevel personality assessments, group therapy, body/mind interactions, and a libertarian redefinition of the doctor-patient relationship. During the 1960s Timothy Leary’s published research and social activism helped trigger the psychopharmalogical and countercultural revolution known as the Psychedelic Movement, with emphasis on altered consciousness, ecstatic ritual, and social experimentation. During the 1970s (in which he spent nearly eight years in prison and exile as a political dissident) Timothy Leary’s work helped expose the mass mind control used by the government behind the scenes. Finally, in the 1990s Leary came to the forefront again with his ground-breaking work on individual freedom and cyberculture - including cybersex.
