This is a talk I gave recently to the Drug Science and Bioscience Societies at the University of York.

I first became interested in psychedelics when I was at school in the 1950s and a young doctor friend was involved in some of the early research on the effects of LSD. When I was 17, before going to Cambridge, I worked in a pharmacology research lab on the effects of LSD and mescaline on chicks. However, it was not until 1970, when I was 28, that I experienced the mind-opening effects of LSD for myself.

In the 1980s, I became friends with Terence McKenna, an expert on the shamanic use of psychedelics, and Ralph Abraham, a chaos mathematician at the University of California, Santa Cruz. We had many discussions about the effects of these substances, including their influence on the growth of computer graphics. I also attended a series of conferences on psychedelics at the Esalen Institute in California and have been in continual contact with recent researchers on the subject.

In this talk, I discuss the nature of psychedelic visions, their possible relationship to dreams and near-death experiences, and the ‘entities’ that many people encounter through them, including machine elves and angels. I look at the cultural history of their use, the emergence of new psychedelic religions such as Santo Daime in Brazil, and suggest that the current psychedelic renaissance is part of a major cultural shift—away from materialism towards a more interconnected worldview.
