Justin explains how Western philosophy has historically privileged rational, sober, and waking states of mind, often dismissing dreams and altered states as unreliable. He explores how psychedelic experiences push against these assumptions, raising deeper questions about knowledge, language, and what counts as real.

The conversation also examines the tension between therapeutic and existential uses of psychedelics, and how medicalization may shape the cultural role these substances play moving forward.

Justin Smith-Ruiu is a professor of history and philosophy of science at the Université Paris Cité and author of On Drugs: Psychedelics, Philosophy, and the Nature of Reality. His work explores intellectual history, consciousness, and the limits of rational thought, and he writes regularly for Harper's, WIRED, and The New York Times.
