About this episode

This episode explores the foundations of knowledge and justification in the context of historical philosophical debates.

When a society tears itself apart over beliefs it cannot justify, philosophy steps in to ask what it really means to know anything at all. Topics explored * The 16th and 17th centuries were marked by intense religious fanaticism and violence (e.g., the Peasant Rebellion, Münster, the Thirty Years' War). * These events pushed thinkers to demand firmer foundations for belief—not mere authority or dogma. * But agreement proved impossible: philosophers disagreed sharply about what counts as justification and what a belief must rest on to be considered rational. * Meanwhile, ancient texts and ideas—especially from Plato and the skeptics—were being rediscovered, raising old questions in a new era. * The lesson introduces epistemology, the study of knowledge, and frames the central issue: What makes a belief justified? * Plato's Justified True Belief (JTB) theory sets the stage, but Agrippa's Regress Argument challenges whether justification is possible at all (the setup for the next steps in the course). * Pyrrhonian skepticism reappears as a powerful alternative: suspend judgment to achieve ataraxia, tranquility free from dogmatic conflict.
