What is knowledge? How much can we know? And how do we know anything? One major field of philosophy is the study of knowledge, i.e., “epistemology” (in Greek “epistÃ©mÃ©” means knowledge and “logos” can mean study). In a series of sharp, focused, and well-animated video lectures, Jennifer Nagel introduces the contemporary field. The first episode is linked here; explore all six of them. If you find epistemology interesting, you may want to consider contemporary versions of skepticism in episode #2 in light of ancient Pyrrhonian Skepticism.
