Terrence McKenna
Dennis and Terrence McKenna traveled to the Amazon in 1971 in search of indigenous DMT-containing plants such as those that constitute the psychedelic brew ayahuasca. They subsequently wrote the book Invisible Landscape about their experiences. Terrence’s “novelty theory,” explained in the book, lead him to predict a novelty singularity in 2012, possibly kicking off the 2012 phenomena.
Terrence went on to become something of a psychedelic guru and author of several books. A collection of interviews with him was published under the title Archaic Revival. Terrence died in 2000.
Dennis took a more academic route, studying the science of entheogens. He still lectures on the subject today.
