Ralph Metzner

Ralph Metzner (1936-2019) was a German-born American psychologist, researcher and author known for his pioneering work in consciousness studies, psychedelic research, and ecological psychology. He served as a psychotherapist and professor emeritus at the California Institute of Integral Studies in San Francisco, where he established the graduate program in consciousness studies. Metzner collaborated with Timothy Leary and Richard Alpert (Ram Dass) at Harvard University in the early 1960s, conducting research on psychedelic substances including LSD and psilocybin. He co-authored "The Psychedelic Experience" (1964), which became a foundational text in psychedelic studies and was based on the Tibetan Book of the Dead. During his later career, Metzner focused on the intersection of consciousness, ecology, and shamanic traditions, writing extensively about altered states of consciousness and ecological preservation. His notable works include "Green Psychology" (1999), "Sacred Vine of Spirits: Ayahuasca" (2006), and "Birth of a Psychedelic Culture" (2010). Metzner's academic contributions extended beyond psychedelic research to include studies in comparative mysticism, consciousness transformation, and ecological sustainability. His work bridged Western scientific approaches with traditional indigenous knowledge systems and practices.
