This book explores the nature and significance of Pyrrhonism, the most prominent and influential form of skepticism in Western philosophy. Not only did Pyrrhonism play an important part in the philosophical scene of the Hellenistic and Imperial age, but it also had a tremendous impact on Renaissance and modern philosophy and continues to be a topic of lively discussion among both scholars of ancient philosophy and epistemologists. The focus and inspiration of the book is the brand of Pyrrhonism expounded in the extant works of Sextus Empiricus. Its aim is twofold: to offer a critical interpretation of some of the central aspects of Sextus’s skeptical outlook and to examine certain debates in contemporary philosophy from a neo-Pyrrhonian perspective. The first part explores the aim of skeptical inquiry, the defining features of Pyrrhonian argumentation, the epistemic challenge posed by the Modes of Agrippa, and the Pyrrhonist’s stance on the requirements of rationality. The second part focuses on present-day discussions of the epistemic significance of disagreement, the limits of self-knowledge, and the nature of rationality. The book will appeal to researchers and graduate students interested in skepticism.

This is the first collection of original essays entirely devoted to a detailed study of the Pyrrhonian tradition. The twelve contributions collected in the present volume combine to offer a historical and systematic analysis of the form of skepticism known as “Pyrrhonism”. They discuss whether the Pyrrhonist is an ethically engaged agent, whether he can claim to search for truth, and other thorny questions concerning ancient Pyrrhonism; explore its influence on certain modern thinkers such as Pierre Bayle and David Hume; and examine Pyrrhonian skepticism in relation to contemporary analytic philosophy.

Scholarship on ancient Pyrrhonism has made tremendous advances over the past three decades, thanks especially to the careful reexamination of Sextus Empiricus’ extant corpus. Building on this momentum, the authors of the eight essays collected here examine some of the most vexed and intriguing exegetical and philosophical questions posed by Sextus’ presentation of this form of skepticism. The essays explore in a new light the skeptical interpretation of Plato, the differences between Pyrrhonism and Cyrenaicism, the Pyrrhonist’s stance on ordinary life, religion, language, and ethics, Sextus’ discussion of our access to our own mental states, and the relationship between Pyrrhonism and epistemic internalism and externalism. These new essays represent a substantial contribution to the advancement of scholarship on Pyrrhonian skepticism.

Sextus Empiricus was the voice of ancient Greek skepticism for posterity, providing a model of skeptical philosophy that remains significant to this day. This volume collects essays discussing Sextus's influence in the history of modern philosophy as well as contemporary engagements with Sextus's version of Pyrrhonian skepticism.

This work examines contemporary theories in knowledge and justification. It presents an analysis of ordinary knowledge claims, showing that they are philosophically unproblematical. It then asks whether theories of justification meet the challenges raised by Empiricus' "Outlines of Pyrrhonism."

Brian C. Ribeiro’s Sextus, Montaigne, Hume: Pyrrhonizers invites us to view the Pyrrhonist tradition as involving all those who share a commitment to the activity of Pyrrhonizing and develops fresh, provocative readings of Sextus, Montaigne, and Hume as radical Pyrrhonizing skeptics.

This volume offers the first bilingual edition of a major text in the history of epistemology, Diogenes Laertius's report on Pyrrho and Timon in his Lives of Eminent Philosophers. Leading experts contribute a philosophical introduction, translation, commentary, and scholarly essays on the nature of Diogenes's report as well as core questions in recent research on skepticism.
