Comments on Declan Smithies’ The Epistemic Role of Consciousness

Declan Smithies’ The Epistemic Role of Consciousness argues for “phenomenal mentalism,” according to which justification is determined synchronically and solely by phenomenally individuated mental states. Moreover, part I of the book argues for a few specific epistemic principles about perception, cognition, and introspection. My comments focus on the discussion of these specific principles and raise worries about the consistency with other ideas in the book, and about the arguments for these principles.
