Research Assistant, University of Adelaide

Dr. Chris Letheby is a philosopher working on issues related to the therapeutic and transformative potential of classic psychedelic drugs. His doctoral research, conducted at the University of Adelaide, presented the first systematic analysis of psychedelic experience within the framework of 21st century philosophy of cognitive science.  In his thesis Letheby argues that an ‘entheogenic conception’ of psychedelics as agents of epistemic and spiritual benefit is both consistent with philosophical naturalism and plausible in light of current scientific knowledge.  Having been awarded his PhD in early 2017, he is currently teaching philosophy at the University of Adelaide and logic at Eynesbury College, while continuing to conduct research on philosophical issues relating to psychedelics.

Psychedelics have a remarkable capacity to violate our ideas about ourselves. Is that why they make people better?
