Timothy
Leary is called a ”high priest of LSD” and a ”psychedelic shaman”. He
believed that LSD showed potential for therapeutic use in psychiatry. He
used LSD himself and developed a philosophy of mind expansion and personal
truth through LSD. After leaving Harvard, he continued to publicly promote the
use of psychedelic drugs and became a well-known figure of
the counterculture of the 1960s, and therefore also in New Age. He
popularized catchphrases that promoted his philosophy, such as
"turn on, tune in, drop out", "set and setting", and
"think for yourself and question authority". He also wrote and spoke
frequently about transhumanist concepts involving space migration,
intelligence increase, and life extension (SMI²LE). Below you can
