# The Agency-First Epistemology of Psychedelics **Keywords:** Epistemology ∙ Agency ∙ Psychedelics∙ Self-know-how ∙ Skills ∙ Self-regulation **Abstract:** Letheby’s book is an engaging and crystal-clear exploration of the philosophical issues raised by the use of psychedelic drugs. In this paper, we focus on the epistemological issues Letheby examines in chapter 8 and argue that his analysis requires an agency-first approach to epistemic evaluation. On an agency-first approach, epistemic evaluation is about identifying the skills agents needs to acquire in order to pursue and fulfil their epistemic goals. **Authors:** [[Lisa Bortolottia and Kathleen Murphy]]
