Outlines of Scepticism, by the Greek philosopher Sextus Empiricus, is a work of major importance for the history of Greek philosophy. It is the fullest extant account of ancient scepticism, and it is also one of our most copious sources of information about the other Hellenistic philosophies. Its first part contains an elaborate exposition of the Pyrrhonian variety of scepticism; its second and third parts are critical and destructive, arguing against 'dogmatism' in logic, epistemology, science and ethics - an approach that revolutionized the study of philosophy when Sextus' works were rediscovered and published in the sixteenth century. This volume presents the accurate and readable translation which was first published in 1994, together with a substantial new historical and philosophical introduction by Jonathan Barnes.

Five Modes of Scepticism examines the argument forms that lie at the heart of Pyrrhonian scepticism as expressed in the writings of Sextus Empiricus. These are the Agrippan modes of disagreement, hypothesis, infinite regression, reciprocity and relativity; modes which are supposed to bring about that quintessentially sceptical mental state of suspended judgement. Stefan Sienkiewicz analyses how the modes are supposed to do this, both individually and collectively, and from two perspectives. On the one hand there is the perspective of the sceptic's dogmatic opponent and on the other there is the perspective of the sceptic himself. Epistemically speaking, the dogmatist and the sceptic are two different creatures with two different viewpoints. The book elucidates the corresponding differences in the argumentative structure of the modes depending on which of these perspectives is adopted. Previous treatments of the modes have interpreted them from a dogmatic perspective; one of the tasks of the present work is to reorient the way in which scholars have traditionally engaged with the modes. Sienkiewicz advocates moving away from the perspective of the sceptic's opponent - the dogmatist - towards the perspective of the sceptic and trying to make sense of how the sceptic can come to suspend judgement on the basis of the Agrippan modes.

A new and accurate translation of an important work of ancient Greek scepticism.

The Outlines of Pyrrhonism by the 2nd century A.D. Greek physician Sextus Empiricus was immensely influential in the history of Western philosophy. The rediscovery and publication of this work in the sixteenth and seventeenth centuries led directly to the skepticism of Montaigne, Gassendi, Bayle, Descartes, Berkeley, Hume, and others, and eventually to the preoccupation of modern philosophy with attempts to refute or otherwise combat philosophical skepticism. In recent years, however, it has become apparent that Pyrrhonism--the form of skepticism professed by Sextus--is in several important respects quite different from the modern forms of skepticism to which the writings of Sextus have given rise. Some of these differences are of particular philosophic interest because they seem to render the ancient form immune to many of the standard responses to skepticism that are made today. In this book, which incorporates a new translation of the Outlines in their entirety, Benson Mates presents Pyrrhonism not as a mere historical curiosity, as has often been done, but as a philosophical position eminently worthy of serious philosophical consideration here and now. His thorough introduction sets the stage by explaining what Pyrrhonism is and what it is not, and by contrasting it in the relevant respects with modern skepticism. He gives particular attention to explicating a number of quasi-technical terms that occur frequently in the Outlines and have decisive bearing on the philosophical content. By rendering these terms more accurately and uniformly in his translation, he seeks to make the essential feautres of Sextus's Pyrrhonism more evident to the reader. The latter part of the book consists of a detailed Commentary, which endeavors to discuss and explain the work, section by section, from a philosophical (as contrasted with a philological) point of view.

"Judicious in every respect: selection, translation and structuring of the texts, footnotes, bibliography, and index. . . . The book of choice for undergraduate courses." --Edward M. Galligan, University of North Carolina

Casey Perin presents a new interpretation of key ideas and arguments in Sextus Empiricus' Outlines of Pyrrhonism, a founding text of the Sceptical tradition in philosophy. Perin examines Sextus' commitment to the search for truth and to certain principles of rationality, the scope of his scepticism, and its consequences for action and agency.

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.
