As a youth, McKenna had a hobby of fossil-hunting from which he acquired a deep scientific appreciation of nature. At the age of 14, he became interested in psychology after reading Carl Jung's book Psychology and Alchemy. At the age of 14, McKenna first became aware of magic mushrooms when he read the article "Seeking the Magic Mushroom" from the May 13, 1957 edition of LIFE magazine. He began smoking cannabis as a teenager.
Soon after graduating, McKenna and Dennis published a book inspired by their Amazon experiences, The Invisible Landscape: Mind, Hallucinogens and the I Ching. The brothers' experiences in the Amazon were the main focus of McKenna's book True Hallucinations, published in 1993. McKenna also began lecturing locally around Berkeley and started appearing on some underground radio stations.
In the early 1980s, McKenna began to speak publicly on the topic of psychedelic drugs, becoming one of the pioneers of the psychedelic movement. His main focus was on the naturally occurring psychedelics such as psilocybin mushrooms (which were the catalyst for his career), ayahuasca, cannabis, and the plant derivative DMT. He conducted lecture tours and workshops promoting natural psychedelics as a way to explore universal mysteries, stimulate the imagination, and re-establish a harmonious relationship with nature. Though associated with the New Age and Human Potential Movements, McKenna himself had little patience for New Age sensibilities. He repeatedly stressed the importance and primacy of the "felt presence of direct experience", as opposed to dogma.
In 1985, McKenna founded Botanical Dimensions with his then-wife, Kathleen Harrison. Botanical Dimensions is a nonprofit ethnobotanical preserve on the Big Island of Hawaii, established to collect, protect, propagate, and understand plants of ethno-medical significance and their lore, and appreciate, study, and educate others about plants and mushrooms felt to be significant to cultural integrity and spiritual well-being. The 19-acre (7.7 ha) botanical garden is a repository containing thousands of plants that have been used by indigenous people of the tropical regions, and includes a database of information related to their purported healing properties. McKenna was involved until 1992, when he retired from the project, following his and Kathleen's divorce earlier in the year. Kathleen still manages Botanical Dimensions as its president and projects director.
After their divorce, McKenna moved to Hawaii permanently, where he built a modernist house and created a gene bank of rare plants near his home. Previously, he had split his time between Hawaii and Occidental, CA.
In late 1999, McKenna described his thoughts concerning his impending death to interviewer Erik Davis:
McKenna died on April 3, 2000, at the age of 53.
McKenna's library of over 3,000 rare books and personal notes was destroyed in a fire in Monterey, California on February 7, 2007. An index of McKenna's library was preserved by his brother Dennis.
Terence McKenna advocated the exploration of altered states of mind via the ingestion of naturally occurring psychedelic substances; for example, and in particular, as facilitated by the ingestion of high doses of psychedelic mushrooms, ayahuasca, and DMT, which he believed was the apotheosis of the psychedelic experience.
He was less enthralled with synthetic drugs, stating, "I think drugs should come from the natural world and be use-tested by shamanically orientated cultures ... one cannot predict the long-term effects of a drug produced in a laboratory."
He also recommended, and often spoke of taking, what he called "heroic doses", which he defined as five grams of dried psilocybin mushrooms, taken alone, on an empty stomach, in silent darkness, and with eyes closed. He believed that when taken this way one could expect a profound visionary experience, believing it is only when "slain" by the power of the mushroom that the message becomes clear.
Although McKenna avoided giving his allegiance to any one interpretation (part of his rejection of monotheism), he was open to the idea of psychedelics as being "trans-dimensional travel". He proposed that DMT sent one to a "parallel dimension" and that psychedelics literally enabled an individual to encounter "higher dimensional entities", or what could be ancestors, or spirits of the Earth, saying that if you can trust your own perceptions it appears that you are entering an "ecology of souls". McKenna also put forward the idea that psychedelics were "doorways into the Gaian mind", suggesting that "the planet has a kind of intelligence, it can actually open a channel of communication with an individual human being" and that the psychedelic plants were the facilitators of this communication.
During the final years of his life and career, McKenna became very engaged in the theoretical realm of technology. He was an early proponent of the technological singularity and in his last recorded public talk, Psychedelics in the age of intelligent machines, he outlined ties between psychedelics, computation technology, and humans. He also became enamored with the Internet, calling it "the birth of [the] global mind", believing it to be a place where psychedelic culture could flourish.
McKenna's hypothesis concerning the influence of psilocybin mushrooms on human evolution is known as "the 'stoned ape' theory."
McKenna's "stoned ape" theory has not received attention from the scientific community and has been criticized for a relative lack of citation to any of the paleoanthropological evidence informing our understanding of human origins. His ideas regarding psilocybin and visual acuity have been criticized as misrepresentations of Fischer et al.'s findings, who published studies of visual perception parameters other than acuity. Criticism has also noted a separate study on psilocybin-induced transformation of visual space, wherein Fischer et al. stated that psilocybin "may not be conducive to the survival of the organism". There is a lack of scientific evidence that psilocybin increases sexual arousal, and even if it does, it would not necessarily entail an evolutionary advantage. Others have pointed to civilizations such as the Aztecs, who used psychedelic mushrooms (at least among the Priestly class), that did not reflect McKenna's model of how psychedelic-using cultures would behave, for example, by carrying out human sacrifice. There are also examples of Amazonian tribes such as the Jivaro and the Yanomami who use ayahuasca ceremoniously and who are known to engage in violent behaviour. This, it has been argued, indicates the use of psychedelic plants does not necessarily suppress the ego and create harmonious societies.
One of the main themes running through McKenna's work, and the title of his second book, was the idea that Western civilization was undergoing what he called an "archaic revival".
His hypothesis was that Western society has become "sick" and is undergoing a "healing process": In the same way that the human body begins to produce antibodies when it feels itself to be sick, humanity as a collective whole (in the Jungian sense) was creating "strategies for overcoming the condition of disease" and trying to cure itself, by what he termed as "a reversion to archaic values". McKenna pointed to phenomena including surrealism, abstract expressionism, body piercing and tattooing, psychedelic drug use, sexual permissiveness, jazz, experimental dance, rave culture, rock and roll and catastrophe theory, amongst others, as his evidence that this process was underway. This idea is linked to McKenna's "stoned ape" theory of human evolution, with him viewing the "archaic revival" as an impulse to return to the symbiotic and blissful relationship he believed humanity once had with the psilocybin mushroom.
The basis of the theory was conceived in the mid-1970s after McKenna's experiences with psilocybin mushrooms at La Chorrera in the Amazon led him to closely study the King Wen sequence of the I Ching.
When examining the King Wen sequence of 64 hexagrams, McKenna noticed a pattern. He analysed the "degree of difference" between the hexagrams in each successive pair and claimed he found a statistical anomaly, which he believed suggested that the King Wen sequence was intentionally constructed, with the sequence of hexagrams ordered in a highly structured and artificial way, and that this pattern codified the nature of time's flow in the world. With the degrees of difference as numerical values, McKenna worked out a mathematical wave form based on the 384 lines of change that make up the 64 hexagrams. He was able to graph the data and this became the Novelty Time Wave.
Peter J. Meyer (Peter Johann Gustav Meyer), in collaboration with McKenna, studied and developed novelty theory, working out a mathematical formula and developing the Timewave Zero software (the original version of which was completed by July 1987), enabling them to graph and explore its dynamics on a computer. The graph was fractal: It exhibited a pattern in which a given small section of the wave was found to be identical in form to a larger section of the wave. McKenna called this fractal modeling of time "temporal resonance", proposing it implied that larger intervals, occurring long ago, contained the same amount of information as shorter, more recent, intervals. He suggested the up-and-down oscillation of the wave shows an ongoing wavering between habit and novelty respectively. With each successive iteration trending, at an increasing level, towards infinite novelty. So according to novelty theory, the pattern of time itself is speeding up, with a requirement of the theory being that infinite novelty will be reached on a specific date.
McKenna believed that events in history could be identified that would help him locate the time wave end date and attempted to find the best-fit of the graph to the data field of human history. The last harmonic of the wave has a duration of 67.29 years. Population growth, peak oil, and pollution statistics were some of the factors that pointed him to an early twenty-first century end date and when looking for a particularly novel event in human history as a signal that the final phase had begun McKenna picked the dropping of the atomic bomb on Hiroshima. This adjusted his graph to reach zero in mid-November 2012. When he later discovered that the end of the 13th baktun in the Maya calendar had been correlated by Western Maya scholars as December 21, 2012, he adopted their end date instead.
Novelty theory is considered to be pseudoscience. Among the criticisms are the use of numerology to derive dates of important events in world history, the arbitrary rather than calculated end date of the time wave and the apparent adjustment of the eschaton from November 2012 to December 2012 in order to coincide with the Maya calendar. Other purported dates do not fit the actual time frames: the date claimed for the emergence of Homo sapiens is inaccurate by 70,000 years, and the existence of the ancient Sumer and Egyptian civilisations contradict the date he gave for the beginning of "historical time". Some projected dates have been criticized for having seemingly arbitrary labels, such as the "height of the age of mammals" and McKenna's analysis of historical events has been criticised for having a eurocentric and cultural bias.

Most Mayanist scholars, such as Mark Van Stone and Anthony Aveni, adhere to the "GMT (Goodman-Martinez-Thompson) correlation" with the Long Count, which places the start date at 11 August 3114 BC and the end date of b'ak'tun 13 at December 21, 2012.[89] This date was also the overwhelming preference of those who believed in 2012 eschatology, arguably, Van Stone suggests, because it was a solstice, and was thus astrologically significant. Some Mayanist scholars, such as Michael D. Coe, Linda Schele and Marc Zender, adhere to the "Lounsbury/GMT+2" correlation, which sets the start date at August 13 and the end date at December 23. Which of these is a better correlation remained unsettled.[90] Coe's initial date was "24 December 2011." He revised it to "11 January AD 2013" in the 1980 2nd edition of his book,[91] not settling on December 23, 2012 until the 1984 3rd edition.[92] The correlation of b'ak'tun 13 as December 21, 2012 first appeared in Table B.2 of Robert J. Sharer's 1983 revision of the 4th edition of Sylvanus Morley's book The Ancient Maya.[93]

The 1975 first edition of McKenna's The Invisible Landscape refers to 2012 (but no specific day during the year) only twice. In the 1993 second edition, McKenna employed December 21, 2012 throughout, the date arrived at by the Mayanist researcher Robert J. Sharer.[94] /wiki/Mayanist
