This paper argues for the following three claims. First, the Agrippan mode from disagreement does not play a secondary role in inducing suspension of judgment. Second, the Pyrrhonist is not committed to the criteria of justification underlying the Five Modes of Agrippa, which nonetheless does not prevent him from non-doxastically assenting to them. And third, some recent objections to Agrippan Pyrrhonism raised by analytic epistemologists and experimental philosophers fail to appreciate the Pyrrhonist's ad hominem style of argumentation and the real challenge posed by the mode from disagreement.

Several scholars familiar with Sextus Empiricus’s Pyrrhonism who have attentively read his Against the Ethicists have gotten the impression that something strange is going on in this book. For, at variance with the ‘official’ Pyrrhonian attitude of universal suspension of judgment, a number of passages of Against the Ethicists seem to ascribe to the Pyrrhonist both a type of negative dogmatism and a form of realism, which together amount to what may be called ‘moderate ethical realism’. The purpose of this paper is to determine whether Sextus does embrace such a position in Against the Ethicists.

In recent years, there has been renewed interest in Pyrrhonism among both philosophers and historians of philosophy. This skeptical tradition is complex and multifaceted, since the Pyrrhonian arguments have been put into the service of different enterprises or been approached in relation to interests which are quite distinct. The diversity of conceptions and uses of Pyrrhonism accounts for the diversity of the challenges it is deemed to pose and of the attempts to meet them. The present volume brings together twelve essays by leading specialists which explore the history and philosophical significance of this form of skepticism: they discuss some thorny questions concerning ancient Pyrrhonism, explore its influence on certain modern thinkers, and examine it in relation to contemporary analytic philosophy. The essays combine historical and exegetical analysis with an assessment of the philosophical merits of the Pyrrhonian outlook, with the aim of understanding it both in its historical context and in connection with contemporary concerns. This volume, the first entirely devoted to a detailed study of the Pyrrhonian tradition, is intended to open up new exegetical and philosophical perspectives on Pyrrhonism and to motivate further examination of certain difficult issues. It will be a valuable resource for scholars of ancient philosophy, historians of modern philosophy, and epistemologists, as well as for graduate students interested in skepticism.

Particularly during the past twenty five years, there has been an outstanding advance in the study of ancient skepticism, both in its Pyrrhonian and Academic varieties. This is reflected in the publication of a considerable number of works about the nature and consistency of those philosophical outlooks, as well as about their influence on the development of early modern philosophy and their relevance to present day epistemological discussions. Most of these works concern Pyrrhonian skepticism. This predominance of interest in Pyrrhonism over Academic skepticism also manifests itself in the fact that, whereas in recent years several new translations of Sextus Empiricus' writings (our principal source for Pyrrhonism) have appeared in the most important European languages, the same has not happened with Cicero's Academica, which is our main source of information about the philosophy of the skeptical Academy. Even though Sextus'.

Julia Annas has affirmed that the kind of modern moral skepticism which denies the existence of objective moral values rests upon a contrast between morality and some other system of beliefs about the world which is not called into doubt. Richard Bett, on the other hand, has argued that the existence of such a contrast is not a necessary condition for espousing that kind of moral skepticism. My purpose in this paper is to show that Bett fails to make a good case against Annas’ thesis. To accomplish this, it will be helpful to consider the Pyrrhonean attitude towards morality as expounded in Sextus Empiricus’ work.

Moral skepticism is at present a vibrant topic of philosophical inquiry. Particularly since the turn of the millennium, the metaethical study of skepticism has profited from advances in general epistemology and findings in empirical sciences, in light of which new arguments for and against moral skepticism have been devised, while the traditional ones have been reexamined. This collection of original essays by leading metaethicists will advance the ongoing debates about various forms of moral skepticism by drawing on recent innovative work on moral disagreement, moral knowledge and justification, moral error theory, moral fictionalism, moral phenomenology, moral psychology, and evolutionary debunking of morality. It will be a valuable resource for professionals and advanced students working in the areas of moral philosophy and moral psychology.

This paper approaches the current epistemological debate on peer disagreement from a neo-Pyrrhonian perspective, thus adopting a form of skepticism which is more radical than those discussed in the literature. It makes use of argumentative strategies found in ancient Pyrrhonism both to show that such a debate rests on problematic assumptions and to block some maneuvers intended to offer an efficacious way of settling a considerable number of peer disputes. The essay takes issue with three views held in the peer disagreement debate: there is an objective fact of the matter about at least most controversial questions; we possess theory-neutral evidence bearing on those questions which grants us access to the truth of the matter; and many peer controversies are resolved by attending to which disputant has correctly evaluated the objective evidence. With respect to the first two views, it is argued that the belief in both objective facts and theory-neutral evidence is subject to fierce dispute, and should not therefore be taken for granted in the discussion of peer disagreement. As for the third view, it is argued that from either a first- or a third-person perspective, there seems to be epistemic symmetry between the disputants which makes it necessary to suspend judgment.
