Theory of Knowledge
An introduction to epistemology from MIT OpenCourseWare, centered on skepticism, the claim that we know nothing at all. The course surveys classical and contemporary skeptical arguments, including brain-in-a-vat and dream scenarios, alongside the major philosophical responses that attempt to defeat them. Materials include lecture notes, reading assignments drawn from historical and contemporary sources, and written assignments that ask students to construct and evaluate arguments about the nature and limits of knowledge. Topics covered include the structure of justification, the regress problem, and different theories of what knowledge requires. The course is self-paced through MIT's OpenCourseWare site, with all materials free to access under a Creative Commons license and no certificate offered. It suits anyone wanting a rigorous, argument-driven entry point into epistemology rather than a survey of philosophy in general.
