John Lilly (January 6, 1915 – September 30, 2001) was an American physician, psychoanalyst and writer.
He was a pioneer researcher into the nature of consciousness using as his principal tools the isolation tank, dolphin communication and psychedelic drugs, sometimes in combination.
He was a prominent member of the Californian counterculture of scientists, mystics and thinkers that arose in the late 1960s and early 70s. Albert Hofmann, Gregory Bateson, Ram Dass, Timothy Leary, Werner Erhard, and Richard Feynman were all frequent visitors to his home.
In the early sixties he was introduced to psychedelics like LSD and Ketamine and began a series of experiments in which he took the psychedelic in an isolation tank and/or in the company of dolphins.
These events are described in his books Programming and Metaprogramming in the Human Biocomputer: Theory and Experiments and The Centre of the Cyclone, both published in 1972.
Later in life, Dr. Lilly laid out the design for a future "communications laboratory" that would be a floating living room where humans and dolphins could chat as equals and where they would find a common language.
He envisioned a time when all killing of whales and dolphins would cease, "not from a law being passed, but from each human understanding innately that these are ancient, sentient earth residents, with tremendous intelligence and enormous life force. Not someone to kill, but someone to learn from."
