Personification of knowledge (Greek Επιστημη, Episteme) in Celsus Library in Ephesus, Turkey.

Knowledge is a familiarity with someone or something, which can include facts, information, descriptions, or skills acquired through experience or education. It can refer to the theoretical or practical understanding of a subject. It can be implicit (as with practical skill or expertise) or explicit (as with the theoretical understanding of a subject); and it can be more or less formal or systematic.^[1] In philosophy, the study of knowledge is called epistemology, and the philosopher Plato famously defined knowledge as "justified true belief." However no single agreed upon definition of knowledge exists, and there are numerous theories to explain it. The following quote from Bertrand Russell's "Theory of Knowledge" illustrates the difficulty in defining knowledge. "The question how knowledge should be defined is perhaps the most important and difficult of the three with which we shall deal. This may seem surprising: at first sight it might be thought that knowledge might be defined as belief which is in agreement with the facts. The trouble is that no one knows what a belief is, no one knows what a fact is, and no one knows what sort of agreement between them would make a belief true. Let us begin with belief."

Knowledge acquisition involves complex cognitive processes: perception, communication, association and reasoning; while knowledge is also said to be related to the capacity of acknowledgment in human beings.^[2]

Theories of knowledge[link]

Robert Reid, Knowledge (1896). Thomas Jefferson Building, Washington, D.C.

The definition of knowledge is a matter of on-going debate among philosophers in the field of epistemology. The classical definition, described but not ultimately endorsed by Plato,^[3] specifies that a statement must meet three criteria in order to be considered knowledge: it must be justified, true, and believed. Some claim that these conditions are not sufficient, as Gettier case examples allegedly demonstrate. There are a number of alternatives proposed, including Robert Nozick's arguments for a requirement that knowledge 'tracks the truth' and Simon Blackburn's additional requirement that we do not want to say that those who meet any of these conditions 'through a defect, flaw, or failure' have knowledge. Richard Kirkham suggests that our definition of knowledge requires that the evidence for the belief necessitates its truth.^[4]

In contrast to this approach, Wittgenstein observed, following Moore's paradox, that one can say "He believes it, but it isn't so", but not "He knows it, but it isn't so".^[5] He goes on to argue that these do not correspond to distinct mental states, but rather to distinct ways of talking about conviction. What is different here is not the mental state of the speaker, but the activity in which they are engaged. For example, on this account, to know that the kettle is boiling is not to be in a particular state of mind, but to perform a particular task with the statement that the kettle is boiling. Wittgenstein sought to bypass the difficulty of definition by looking to the way "knowledge" is used in natural languages. He saw knowledge as a case of a family resemblance. Following this idea, "knowledge" has been reconstructed as a cluster concept that points out relevant features but that is not adequately captured by any definition.^[6]

Communicating knowledge[link]

Los portadores de la antorcha

Symbolic representations can be used to indicate meaning and can be thought of as a dynamic process. Hence the transfer of the symbolic representation can be viewed as one ascription process whereby knowledge can be transferred. Other forms of communication include observation and imitation, verbal exchange, and audio and video recordings. Philosophers of language and semioticians construct and analyze theories of knowledge transfer or communication.^{[citation needed]}

While many would agree that one of the most universal and significant tools for the transfer of knowledge is writing (of many kinds), argument over the usefulness of the written word exists however, with some scholars skeptical of its impact on societies. In his collection of essays Technopoly Neil Postman demonstrates the argument against the use of writing through an excerpt from Plato's work Phaedrus (Postman, Neil (1992) Technopoly, Vintage, New York, pp 73). In this excerpt the scholar Socrates recounts the story of Thamus, the Egyptian king and Theuth the inventor of the written word. In this story, Theuth presents his new invention "writing" to King Thamus, telling Thamus that his new invention "will improve both the wisdom and memory of the Egyptians" (Postman, Neil (1992) Technopoly, Vintage, New York, pp 74). King Thamus is skeptical of this new invention and rejects it as a tool of recollection rather than retained knowledge. He argues that the written word will infect the Egyptian people with fake knowledge as they will be able to attain facts and stories from an external source and will no longer be forced to mentally retain large quantities of knowledge themselves (Postman, Neil (1992) Technopoly, Vintage, New York,pp 74).

Andrew Robinson also highlights, in his work The Origins of Writing, the possibility for writing to be used to spread false information and therefore the ability of the written word to decrease social knowledge (Robinson, Andrew (2003) The Origins of Writing in Crowley and Heyer (eds) Communication in History: Technology, Culture, Society, Boston pp 34). People are often internalizing new information which they perceive to be knowledge but in reality fill their minds with false knowledge.

The above points are moot in the modern world. Verbal communication lends itself to the spread of falsehoods much more so than written, as there is no record of exactly what was said or who originally said it (usually neither the source nor the content can be verified). Gossip and rumors are common examples. As to value of writing, the extent of human knowledge is now so great that it is only possible to record it and to communicate it through writing. Major libraries today can have millions of books of knowledge (in addition to works of fiction). It is only recently that audio and video technology for recording knowledge have become available and the use of these still requires replay equipment and electricity. Verbal teaching and handing down of knowledge is limited to those few who would have contact with the transmitter person - far too limited for today's world. Writing is still the most available and most universal of all forms of recording and transmitting knowledge. It stands unchallenged as mankind's primary technology of knowledge transfer down through the ages and to all cultures and languages of the world.

Situated knowledge[link]

Situated knowledge is knowledge specific to a particular situation.^[7]

Some methods of generating knowledge, such as trial and error, or learning from experience, tend to create highly situational knowledge. One of the main attributes of the scientific method is that the theories it generates are much less situational than knowledge gained by other methods.^{[citation needed]} Situational knowledge is often embedded in language, culture, or traditions.^{[citation needed]}

Knowledge generated through experience is called knowledge "a posteriori", meaning afterwards. The pure existence of a term like "a posteriori" means this also has a counterpart. In this case that is knowledge "a priori", meaning before. The knowledge prior to any experience means that there are certain "assumptions" that one takes for granted. For example if you are being told about a chair it is clear to you that the chair is in space, that it is 3D. This knowledge is not knowledge that one can "forget", even someone suffering from amnesia experiences the world in 3D. See also: a priori and a posteriori.^{[citation needed]}

Partial knowledge[link]

One discipline of epistemology focuses on partial knowledge. In most cases, it is not possible to understand an information domain exhaustively; our knowledge is always incomplete or partial. Most real problems have to be solved by taking advantage of a partial understanding of the problem context and problem data, unlike the typical math problems one might solve at school, where all data is given and one is given a complete understanding of formulas necessary to solve them.^{[citation needed]}

This idea is also present in the concept of bounded rationality which assumes that in real life situations people often have a limited amount of information and make decisions accordingly.

Scientific knowledge[link]

The development of the scientific method has made a significant contribution to how knowledge is acquired. To be termed scientific, a method of inquiry must be based on gathering observable and measurable evidence subject to specific principles of reasoning and experimentation.^[8] The scientific method consists of the collection of data through observation and experimentation, and the formulation and testing of hypotheses.^[9] Science, and the nature of scientific knowledge have also become the subject of Philosophy. As science itself has developed, knowledge has developed a broader usage which has been developing within biology/psychology—discussed elsewhere as meta-epistemology, or genetic epistemology, and to some extent related to "theory of cognitive development".    

Sir Francis Bacon, "Knowledge is Power"

Note that "epistemology" is the study of knowledge and how it is acquired. Science is “the process used everyday to logically complete thoughts through inference of facts determined by calculated experiments." Sir Francis Bacon was critical in the historical development of the scientific method; his works established and popularized an inductive methodology for scientific inquiry. His famous aphorism, "knowledge is power", is found in the Meditations Sacrae (1597).^[10]

Until recent times, at least in the Western tradition, it was simply taken for granted that knowledge was something possessed only by humans — and probably adult humans at that. Sometimes the notion might stretch to (ii) Society-as-such, as in (e.g.) "the knowledge possessed by the Coptic culture" (as opposed to its individual members), but that was not assured either. Nor was it usual to consider unconscious knowledge in any systematic way until this approach was popularized by Freud.^[11]

Other biological domains where "knowledge" might be said to reside, include: (iii) the immune system, and (iv) in the DNA of the genetic code. See the list of four "epistemological domains":   Popper, (1975);^[12] and Traill (2008:^[13] Table S, page 31)—also references by both to Niels Jerne.

Such considerations seem to call for a separate definition of "knowledge" to cover the biological systems. For biologists, knowledge must be usefully available to the system, though that system need not be conscious. Thus the criteria seem to be:

• The system should apparently be dynamic and self-organizing (unlike a mere book on its own).
• The knowledge must constitute some sort of representation of "the outside world",^[14] or ways of dealing with it (directly or indirectly).
• Some way must exist for the system to access this information quickly enough for it to be useful.

Scientific knowledge may not involve a claim to certainty, maintaining skepticism means that a scientist will never be absolutely certain when they are correct and when they are not. It is thus an irony of proper scientific method that one must doubt even when correct, in the hopes that this practice will lead to greater convergence on the truth in general.^[15]

Religious meaning of knowledge[link]

In many expressions of Christianity, such as Catholicism and Anglicanism, knowledge is one of the seven gifts of the Holy Spirit.^[16]

The Old Testament's tree of the knowledge of good and evil contained the knowledge that separated Man from God: "And the LORD God said, Behold, the man is become as one of us, to know good and evil…" (Genesis 3:22)

In Gnosticism divine knowledge or gnosis is hoped to be attained. In Thelema knowledge and conversation with one's Holy Guardian Angel is the purpose of life.^{[citation needed]}

विद्या दान (Vidya Daan) i.e. knowledge sharing is a major part of Daan, a tenet of all Dharmic Religions.^[17] Hindu Scriptures present two kinds of knowledge, Paroksh Gyan and Prataksh Gyan. Paroksh Gyan (also spelled Paroksha-Jnana) is secondhand knowledge: knowledge obtained from books, hearsay, etc. Prataksh Gyan (also spelled Prataksha-Jnana) is the knowledge borne of direct experience, i.e., knowledge that one discovers for oneself.^[18] Jnana yoga ("path of knowledge") is one of three main types of yoga expounded by Krishna in the Bhagavad Gita. (It is compared and contrasted with Bhakti Yoga and Karma yoga.)

In Islam, knowledge (Arabic: علم, ʿilm) is given great significance. "The Knowing" (al-ʿAlīm) is one of the 99 names reflecting distinct attributes of God. The Qur'an asserts that knowledge comes from God (2:239) and various hadith encourage the acquisition of knowledge. Muhammad is reported to have said "Seek knowledge from the cradle to the grave" and "Verily the men of knowledge are the inheritors of the prophets". Islamic scholars, theologians and jurists are often given the title alim, meaning "knowledgable".^{[citation needed]}

In Jewish tradition, knowledge (Hebrew: דעת da'ath) is considered one of the most valuable traits a person can acquire. Observant Jews recite three times a day in the Amidah "Favor us with knowledge, understanding and discretion that come from you. Exalted are you, Existent-One, the gracious giver of knowledge." The Tanakh states, "A wise man gains power, and a man of knowledge maintains power", and "knowledge is chosen above gold".

Michael Lee Wesch (born June 22, 1975) is associate professor of cultural anthropology at Kansas State University. Wesch's work also includes media ecology and the emerging field of digital ethnography, where he studies the effect of new media on human interaction.

Wesch is a cultural anthropologist and media ecologist exploring the effects of new media on human interaction. He graduated summa cum laude from the Kansas State University Anthropology Program in 1997 and returned as a faculty member in 2004 after receiving his PhD in Anthropology at the University of Virginia. There he pursued research on social and cultural change in Melanesia, focusing on the introduction of print and print-based practices like mapping and census-taking in the remote Mountain Ok region of Papua New Guinea where he lived for a total of 18 months from 1999-2003. This work inspired Wesch to examine the effects of new media more broadly, especially digital media. Also as a consequence of this trip, Dr. Wesch has gained some command in the Tok Pisin language, a primary lingua franca of Papua New Guinea.

To this end, Wesch is launching the Digital Ethnography Working Group, a team of undergraduates exploring human uses of digital technology. Coinciding with the launch of this group, Wesch created a short video, "Web 2.0 ... The Machine is Us/ing Us." Released on YouTube on January 31, 2007, it quickly became the most popular video in the blogosphere and was viewed over 10 million times. Wesch has won several awards for his work with video, including a Wired Magazine Rave Award and the John Culkin Award for Outstanding Media Praxis from the Media Ecology Association.

Wesch's videos are part of his broader efforts to pursue the possibilities of digital media to extend and transform the way ethnographies are presented. Wesch is also a multiple award-winning teacher active in the development of innovative teaching techniques. Most notably, Wesch has developed a highly-acclaimed "World Simulation" for large introductory classes in cultural anthropology. On Nov. 20, 2008, CASE and the Carnegie Foundation for the Advancement of Teaching honored Wesch as Professor of the Year.[1]

Currently he is the coordinator for the Peer Review of Teaching Project at Kansas State University, part of a broader nation-wide consortium of universities pursuing new ways to improve and evaluate student learning. He is also working with the Educause Center for Applied Research on "The Tower and the Cloud" project, examining "the question of how higher education institutions (The Tower) may interoperate with the emerging network-based business and social paradigm (The Cloud)."

Administrating Tests[link]

Dr. Wesch is significant in that the final exams for his anthropology classes only have one question: Why are you here? The responses must be an essay of a minimum of 800 words, and a maximum of 1500 words.

Terence Kemp McKenna (November 16, 1946 – April 3, 2000) was an American philosopher, psychonaut, researcher, teacher, lecturer and writer on many subjects, such as human consciousness, language, psychedelic drugs, the evolution of civilizations, the origin and end of the universe, alchemy, and extraterrestrial beings.

Biography[link]

Early life[link]

Terence McKenna grew up in Paonia, Colorado.^[1] He was introduced to geology through his uncle and developed a hobby of solitary fossil hunting in the arroyos near his home.^[2] From this he developed a deep artistic and scientific appreciation of nature.

At age 16, McKenna moved to Los Altos, California to live with family friends for a year. He finished high school in Lancaster, CA.^[1] In 1963, McKenna was introduced to the literary world of psychedelics through The Doors of Perception and Heaven and Hell by Aldous Huxley and certain issues of The Village Voice that talked about psychedelics.^[1][3]

McKenna claimed that one of his early psychedelic experiences with morning glory seeds showed him "that there was something there worth pursuing."^[1] In an audio interview Terence Mckenna claims to have started smoking cannabis regularly during the summer following his 17th birthday.

Studying and traveling[link]

In 1965, McKenna enrolled in the University of California, Berkeley^[4] to study art history.^[1] In 1967, while in college, he discovered and begun studying shamanism through the study of Tibetan folk religion.^[5] That year, which he called his "opium and kabbala phase"^[6] he also traveled to Jerusalem, where he met Kathleen Harrison, who would later become his wife.^[6]

In 1969, McKenna traveled to Nepal led by his "interest in Tibetan painting and hallucinogenic shamanism."^[6] During his time there, he studied the Tibetan language and worked as a hashish smuggler, until "one of his Bombay-to-Aspen shipments fell into the hands of U. S. Customs." He was forced to move to avoid capture by Interpol.^[6] He wandered through Southeast Asia viewing ruins, collected butterflies in Indonesia, and worked as an English teacher in Tokyo. He then went back to Berkeley to continue studying biology, which he called "his first love".^[6]

After the partial completion of his studies, and his mother's death from cancer in 1971,^[7] McKenna, his brother Dennis, and three friends traveled to the Colombian Amazon in search of oo-koo-hé, a plant preparation containing dimethyltryptamine (DMT). Instead of oo-koo-hé they found various forms of ayahuasca, or yagé, and gigantic Psilocybe cubensis which became the new focus of the expedition.^[6] In La Chorrera, at the urging of his brother, he was the subject of a psychedelic experiment which he claimed put him in contact with "Logos": an informative, divine voice he believed was universal to visionary religious experience.^[6] The voice's reputed revelations and his brother's simultaneous peculiar experience prompted him to explore the structure of an early form of the I Ching, which led to his "Novelty Theory".^[6] During their stay in the Amazon, McKenna also became romantically involved with his translator, Ev.^[6]

In 1972, McKenna returned to Berkeley to finish his studies.^[4] There he decided to switch majors to a Bachelor of Science in ecology and conservation, in a then new experimental section of the same university called the Tussman Experimental College.^[1] During his studies, he would also develop techniques for cultivating psilocybin mushrooms with Dennis.^[6]

In 1975, he parted with his girlfriend, Ev, when she left him for one of his friends from Berkeley. Their parting left him "tormented with migraines and living alone".^[6] He graduated in 1975.^[8] That same year, he began a relationship with Kathleen Harrison, whom he had met in Jerusalem.

Soon after graduating, McKenna and Dennis published a book inspired by their Amazon experiences, The Invisible Landscape: Mind, Hallucinogens and the I Ching. He also began lecturing.^[4] The brothers' experiences in the Amazon would later play a major role in McKenna's book True Hallucinations, published in 1993.^[6] In 1976, the brothers published what they had learned about the cultivation of mushrooms in a book entitled Psilocybin - Magic Mushroom Grower's Guide under the pseudonyms "OT Oss" and "ON Oeric".^[9]

Later life[link]

In the early 1980s, McKenna began to speak publicly on the topic of psychedelic drugs, lecturing extensively and conducting weekend workshops. 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 felt experience, as opposed to dogma.^[10] Timothy Leary once introduced him as "one of the five or six most important people on the planet."^[11]

He soon became a fixture of popular counterculture. His growing popularity culminated in the early-to-mid-1990s with the publication of several books: True Hallucinations, relating the tale of his 1971 La Chorrera experience; Food of the Gods; and The Archaic Revival. He became a popular personality in the psychedelic rave/dance scene of the early 1990s, with frequent spoken word performances at raves and contributions to psychedelic and goa trance albums by The Shamen, Spacetime Continuum, Alien Project, Capsula, Entheogenic, Zuvuya, Shpongle, and Shakti Twins. His speeches were, and are, sampled by many. In 1994 he appeared as a speaker at the Starwood Festival, documented in the book Tripping by Charles Hayes. His lectures were produced on both cassette tape and CD.^[13]

McKenna was a colleague of chaos mathematician Ralph Abraham, and biologist Rupert Sheldrake, creator of the theory of "morphogenetic fields", not to be confused with the mainstream usage of the same term. He conducted several public debates known as trialogues with them from the late 1980s until his death. Books containing transcriptions of some of these events were published. He was also a friend and associate of Ralph Metzner, Nicole Maxwell, and Riane Eisler, participating in joint workshops and symposia with them. He was a personal friend of Tom Robbins, and influenced the thought of many scientists, writers, artists, and entertainers. His influences include comedian Bill Hicks, whose routines about psychedelic drugs drew heavily from McKenna's works. He is also the inspiration for the Twin Peaks character Dr. Jacoby.^[14]

In addition to psychedelic drugs, McKenna spoke on the subjects of virtual reality, which he saw as a way to artistically communicate the experience of psychedelics; techno-paganism; artificial intelligence; evolution; extraterrestrials; and aesthetic theory, specifically about art/visual experience as information representing the significance of hallucinatory visions experienced under the influence of psychedelics.

In 1985,^[8] McKenna co-founded Botanical Dimensions with his then-wife Kathleen, a nonprofit ethnobotanical preserve in Hawaii, where he lived for many years before he died. In 1997 he and Kathleen divorced.^[15] Before moving to Hawaii permanently, McKenna split his time between Hawaii and Occidental, located in the redwood-studded hills of Sonoma County, California.

Death[link]

A longtime sufferer of migraines, in mid-1999 McKenna returned to his home on the big island of Hawaii after a long lecturing tour. He began to suffer from increasingly painful headaches. This culminated in three brain seizures in one night, which he claimed were the most powerful psychedelic experiences he had ever known. Upon his emergency trip to the hospital on Oahu, Terence was diagnosed with glioblastoma multiforme, a highly aggressive form of brain cancer. For the next several months he underwent various treatments, including experimental gamma knife radiation treatment. According to Wired magazine, McKenna was worried that his tumour was caused by his 35-years of smoking cannabis; though his doctors assured him there was no causal relation.^[15]

In late 1999, Erik Davis conducted what would be the last interview of McKenna.^[16] During the interview McKenna also talked about the announcement of his death:

McKenna died on April 3, 2000, at the age of 53, with his loved ones at his bedside. He is survived by his brother Dennis, his son Finn, and his daughter Klea.

Library fire[link]

On February 7, 2007, McKenna's library of rare books and personal notes was destroyed in a fire which burned offices belonging to Big Sur's Esalen Institute which was storing the collection. An index maintained by his brother Dennis survives, though little else.^[18]

Ideas[link]

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, and DMT, which he believed was the apotheosis of the psychedelic experience. He spoke of the "jeweled, self-dribbling basketballs" or "self-transforming machine elves" that one encounters in that state.

Although he 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"; literally, enabling an individual to encounter what could be ancestors, or spirits of earth.^[10] He remained opposed to most forms of organized religion or guru-based forms of spiritual awakening.

Either philosophically or religiously, he expressed admiration for Marshall McLuhan, Pierre Teilhard de Chardin, Gnostic Christianity, Alfred North Whitehead and Alchemy. McKenna always regarded the Greek philosopher Heraclitus as his favorite philosopher.^[11]

He also expressed admiration for the works of James Joyce (calling Finnegans Wake "the quintessential work of art, or at least work of literature of the 20th century")^[20] and Vladimir Nabokov: McKenna once said that he would have become a Nabokov lecturer if he had never encountered psychedelics.

"Stoned Ape" theory of human evolution[link]

In his book Food of the Gods,^[21] McKenna proposed that the transformation from humans' early ancestors Homo erectus to the species Homo sapiens mainly had to do with the addition of the mushroom Psilocybe cubensis in its diet - an event which according to his theory took place in about 100,000 BC (this is when he believed that the species diverged from the Homo genus). He based his theory on the main effects, or alleged effects, produced by the mushroom. One of the effects that comes about from the ingestion of low doses, which agrees with one of scientist Roland Fischer's findings from the late 1960s-early 1970s,^[22] is it significantly improves the visual acuity of humans - so theoretically, of other human-like mammals too. According to McKenna, this effect would have definitely proven to be of evolutionary advantage to humans' omnivorous hunter-gatherer ancestors that would have stumbled upon it "accidentally"; as it would make it easier for them to hunt.

In higher doses, McKenna claims, the mushroom acts as a sexual stimulator, which would make it even more beneficial evolutionarily, as it would result in more offspring. At even higher doses, the mushroom would have acted to "dissolve boundaries", which would have promoted community-bonding and group sexual activities-that would result in a mixing of genes and therefore greater genetic diversity. Generally McKenna believed that the periodic ingestion of the mushroom would have acted to dissolve the ego in humans before it ever got the chance to grow in destructive proportions. In this context, he likened the ego to a cancerous tumor that can grow uncontrollable and become destructive to its host. In his own words:

Wherever and whenever the ego function began to form, it was akin to a cancerous tumor or a blockage in the energy of the psyche. The use of psychedelic plants in a context of shamanic initiation dissolved-as it dissolves today-the knotted structure of the ego into undifferentiated feeling, what Eastern philosophy calls the Tao.

—Terence McKenna, Food of the Gods

The mushroom, according to McKenna, had also given humans their first truly religious experiences (which, as he believed, were the basis for the foundation of all subsequent religions to date). Another factor that McKenna talked about was the mushroom's potency to promote linguistic thinking. This would have promoted vocalisation, which in turn would have acted in cleansing the brain (based on a scientific theory that vibrations from speaking cause the precipitation of impurities from the brain to the cerebrospinal fluid), which would further mutate the brain. All these factors according to McKenna were the most important factors that promoted evolution towards the Homo sapiens species. After this transformation took place, the species would have begun moving out of Africa to populate the rest of the planet ^[21] Later on, this theory by McKenna was given the name "The 'Stoned Ape' Theory of Human Evolution".^[23]

Novelty theory[link]

McKenna's Timewave zero is a numerological formula that purports to calculate the ebb and flow of "novelty", defined as increase over time in the universe's interconnectedness, or organized complexity. ^[24] According to McKenna, the universe has a teleological attractor at the end of time that increases interconnectedness, eventually reaching a singularity of infinite complexity in 2012, at which point anything and everything imaginable will occur simultaneously. He conceived this idea over several years in the early to mid-1970s while using psilocybin and DMT.^[24]

McKenna expressed "novelty" in a computer program which purportedly produces a waveform known as "timewave zero" or the "timewave". Based on McKenna's interpretation of the King Wen sequence of the I Ching, ^[15] the graph appears to show great periods of novelty corresponding with major shifts in humanity'sbiological and sociocultural evolution. He believed that the events of any given time are recursively related to the events of other times, and chose the atomic bombing of Hiroshima as the basis for calculating his end date of November 2012. When he later discovered this date's proximity to the end of the 13th b'ak'tun of the Maya calendar, he revised his hypothesis so that the two dates matched. ^[25]

The 1975 first edition of The Invisible Landscape refers to 2012 (but no specific day during the year) only twice. In the 1993 second edition, McKenna employed Sharer's date^{[Note d]} of 21 December 2012 throughout. ^[26]
