This course traces the origins of skepticism from its roots in Pyrrho of Elis's encounter with Indian Gymnosophists during Alexander the Great's 334 BCE campaign to its later use as a therapeutic method in Roman medicine. Lecture 1 covers the Equipollence Framework and Epoche, showing how Pyrrho developed the practice of suspending judgment to achieve Ataraxia, while warning against the pitfall of Nihilistic Paralysis. Lecture 2 examines the Academic shift under Arcesilaus and Carneades in the 2nd century BCE, where the Probabilism Framework replaced total suspension with the use of persuasive impressions for action, and identifies the Certitude Trap as the risk of treating probable beliefs as absolute truths. Lecture 3 presents Sextus Empiricus's Ten Tropes of Aenesidemus in 2nd century CE Rome as a diagnostic toolkit for dismantling dogmatic anxiety, with the Cynic's Shield as the misuse that blocks emotional growth. Each lecture ends with a bridging rule that applies the historical method to modern decisions: the 50/50 Perception rule for listing opposing reasons, the 70% Confidence Threshold for acting on incomplete data, and the Diagnostic Doubt Check for testing stressful thoughts by shifting perspective, distance, and context.
