Editing Timothy Leary (section)

===Post-Millbrook===
At the end of 1967, Leary moved to [[Laguna Beach, California]], and made many friends in Hollywood. "When he married his third wife, Rosemary Woodruff, in 1967, the event was directed by Ted Markland of ''[[Bonanza]]''. All the guests were on acid."<ref name="Mansnerus"/>

In the late 1960s and early 1970s, Leary formulated what became his [[eight-circuit model of consciousness]] in collaboration with writer [[Brian Barritt]]. The essay "The Seven Tongues of God" claimed that human brains have seven circuits producing seven levels of consciousness. This later became seven circuits in Leary's 1973 monograph ''[[Neurologic (book)|Neurologic]]'', which he wrote while he was in prison. The eight-circuit idea was not exhaustively formulated until the publication of ''Exo-Psychology'' by Leary and [[Robert Anton Wilson]]'s ''[[Cosmic Trigger]]'' in 1977. Wilson contributed to the model after befriending Leary in the early 1970s, and used it as a framework for further exposition in his book ''[[Prometheus Rising]]'', among other works.{{efn-ua|{{harvnb|Wilson|2000|p=6}}: "The eight-circuit model of consciousness in this book and much of its future-vision derive from the writings of Dr. Timothy Leary, whose letters and conversations have also influenced many other ideas herein."}}

Leary believed that the first four of these circuits ("the Larval Circuits" or "Terrestrial Circuits") are naturally accessed by most people at transition points in life such as puberty. The second four circuits ("the Stellar Circuits" or "Extra-Terrestrial Circuits"), Leary wrote, were "evolutionary offshoots" of the first four that would be triggered at transition points as humans evolve further. These circuits, according to Leary, would equip humans to live in space and expand consciousness for further scientific and social progress. Leary suggested that some people might trigger these circuits sooner through meditation, yoga, or psychedelic drugs specific to each circuit. He suggested that the feelings of floating and uninhibited motion sometimes experienced with marijuana demonstrated the purpose of the higher four circuits. The function of the fifth circuit was to accustom humans to life at a zero gravity environment.{{sfnp|Wilson|1991|pp=211–213}} Leary did not specify the location of the eight circuits in any brain structures, neural organization, or chemical pathways.{{sfnp|Leary|1977|p=11}} He wrote that a higher intelligence "located in interstellar nuclear-gravitational-quantum structures" gave humans the eight circuits. A "U.F.O. message" was encoded in human DNA.{{sfnp|Leary|1977|p=16}}

Many researchers believed that Leary provided little scientific evidence for his claims. Even before he began working on psychedelics, he was known as a theoretician rather than a data collector. His most ambitious pre-psychedelic work was ''Interpersonal Diagnosis Of Personality''. The reviewer for ''The British Medical Journal'', H. J. Eysenck, wrote that Leary created a confusing and overly broad rubric for testing psychiatric conditions. "Perhaps the worst failing of the book is the omission of any kind of proof for the validity and reliability of the diagnostic system," Eysenck wrote. "It is simply not enough to say" that the accuracy of the system "can be checked by the reader" in clinical practice.<ref>{{cite journal |last1=Eysenck |first1=H.

Penn State psychology researcher Jerome E. Singer reviewed the book and singled out Leary as the worst offender in a work containing "melanges of hucksterism". In place of scientific data about the effects of LSD, Leary used metaphors about "galaxies spinning" faster than the speed of light and a cerebral cortex "turned on to a much higher voltage".<ref>{{cite journal |last1=Singer |first1=Jerome |title=Review: The Psychedelic Reader |journal=American Sociological Review |date=April 1966 |volume=31 |issue=2 |page=284|doi=10.2307/2090932 |jstor=2090932 }}</ref>
