What epistemology asks, the main theories of truth (correspondence, coherence, pragmatist and deflationary), knowledge as justified true belief and the Gettier problem, theories of justification, skepticism from Descartes to the brain in a vat, evidence and degrees of belief, how science produces knowledge, and how to rely wisely on testimony and experts.

The aim is understanding, not persuasion: you should finish able to explain each position as its best defenders would, state the strongest objections to it, and apply these ideas to everyday questions about what to believe and whom to trust. No background needed.
