The classical Indian Cārvāka (“Materialist”) tradition contains three branches with regard to the means of knowledge (pramāṇas). First, the standard Cārvākas accept a single means of knowledge, perception, supporting this view with a critique of the reliability and coherence of inference (anumāna). Second, the “more educated” Cārvākas as well as Purandara endorse a form of inference limited to empirical matters. Third, radical skeptical Cārvākas like Jayarāśi attempt to undermine all accounts or technical definitions of the means of knowledge (even perception) in order to enjoy a life free from philosophical and religious speculation. These branches respectively present something akin to David Hume’s problem of induction, endorse a fallibilistic, mitigated skepticism, and embody a thoroughgoing skepticism about philosophy itself. While all three branches are skeptics about religious matters, each branch exemplifies a different variety of epistemological skepticism.

This chapter considers the literature associated with explorations of consciousness in Indian philosophy. It focuses on a range of methodological and conceptual issues, drawing on three main sources: the naturalist theories of mind of Nyaya and Vaisesika, the mainly phenomenological accounts of mental activity and consciousness of Abhidharma and Yogacara Buddhism, and the subjective transcendental theory of consciousness of Advaita Vedanta. The contributions of Indian philosophers to the study of consciousness are examined not simply as a contribution to intellectual history, but rather with a view to evaluating their relevance to contemporary issues, specifically to the mind-body problem. The presence of dualist positions with strong naturalist undercurrents in Indian philosophy, especially in the Nyaya and Samkhya traditions, rules out the possibility of treating the mind-body problem as an idiosyncratic feature of Cartesian metaphysics.
