It is widely assumed that it is rational to suspend one’s belief regarding a certain proposition only if one’s evidence is neutral regarding that proposition. In this paper I broaden this condition, and defend, on the basis of an improved ancient argument, that it is rational to suspend one’s belief even if the available evidence is not neutral – or even close to neutral.

Sextus responds to the Dogmatists’ criticism that the Sceptics cannot investigate Dogmatic theses, formulating his own version of Meno’s puzzle against them. He thus forces them to adopt υοεῐυ ἁπλῶς – a way of thinking that does not carry any commitment to the reality of what someone thinks – as their only solution to the puzzle and as the necessary starting point of their investigation. Nοεῐυ ἁπλῶς avoids Dogmatic assumptions without making use of the Sceptical argumentation that leads to suspension (...) of judgment. It constitutes a novel answer to Meno’s puzzle, Dogmatism- and Scepticism-free, with important consequences both for Dogmatism and for Scepticism. (shrink)

Sextus Empiricus présente le scepticisme néo-pyrrhonien comme une philosophie qui cherche la vérité (PH I, 1-3). Il est difficile de le croire, pourtant, lorsque l ’ on étudie les longues séries d ’ arguments qu ’ il met en opposition afin de produire l ’ isosthénie, la force égale des arguments, qui amène à la suspension du jugement. Comment faut-il interpréter ce qui pourrait apparaître comme un décalage entre la théorie et la pratique du scepticisme? Plutôt que de conclure à (...) l ’ inconséquence du scepticisme, (i) l ’ article se propose de reprendre à nouveaux frais les passages où Sextus présente le scepticisme comme une recherche de la vérité. Pour ce faire, il faut d ’ une part (ii) lier cette présentation à l ’ opération de différenciation entre le scepticisme de la Nouvelle Académie et celui des néo-pyrrhoniens ; d ’ autre part (iii) revenir sur la pratique du scepticisme par les néo-pyrrhoniens. Loin d ’ être une recherche de la vérité, le pyrrhonisme présenté par Sextus Empiricus recherche l ’ incertitude à l ’ origine du bonheur sceptique. (shrink)

In his Pyrrhonian Outlines , Sextus Empiricus employs an argument based upon the possibility of disagreement in order to show that one should not assent to a Dogmatic claim to which at present one cannot oppose a rival claim. The use of this argument seems to be at variance with the Pyrrhonian stance, both because it does not seem to accord with the definition of Skepticism and because the argument appears to entail that the search for truth is doomed to (...) failure. In the present paper, I examine the passages in which Sextus utilizes the argument from possible disagreement and offer an interpretation that makes the use of this argument compatible with the Pyrrhonian outlook.

The Pyrrhonist’s argumentative practice is characterized by at least four features. First, he makes a therapeutic use of arguments: he employs arguments that differ in their persuasiveness in order to cure his dogmatic patients of the distinct degrees of conceit and rashness that afflict them. Secondly, his arguments are for the most part dialectical: when offering an argument to oppose it to another argument advanced by a given dogmatist, he accepts in propria persona neither the truth of its premises and (...) conclusion nor the validity of its logical form. Thirdly, he avails himself of arguments in his own open-minded inquiry into the truth about a wide range of topics. Fourthly, Pyrrhonian argumentation is oppositional inasmuch as it typically works by producing oppositions among arguments that appear to the Pyrrhonist to be equipollent. In this article, I focus on the first three features with the aim of both shedding some light on them and determining whether they are in tension or coherently relate to each other. (shrink)

Sextus Empiricus associates the skeptical stance with the activity of inquiry or investigation. My purpose in this paper is to examine the Pyrrhonist's involvement in that activity because getting an accurate understanding of the nature and purpose of skeptical inquiry makes it possible to delineate some of the distinctive traits of Pyrrhonism as a kind of philosophy. I defend the minority view among specialists according to which (i) Sextus describes both the prospective Pyrrhonist and the full-fledged Pyrrhonist as inquirers into (...) truth, and (ii) the full-fledged Pyrrhonist can, without inconsistency, engage in truth-directed inquiry.

Ancient philosophy knew two main skeptical traditions: the Pyrrhonian and the Academic. In this final paper of the three‐part series devoted to ancient skepticism, I present some of the topics about Academic skepticism which have recently been much debated in the specialist literature. I will be concerned with the outlooks of Arcesilaus, Carneades, and Philo of Larissa.

Pyrrhonism was one of the two main ancient skeptical traditions. In this second paper of the three‐part series devoted to ancient skepticism, I present and discuss some of the issues on Pyrrhonian skepticism which have been the focus of much attention in the recent literature. The topics to be addressed concern the outlooks of Pyrrho, Aenesidemus, and Sextus Empiricus.

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.

Sextus Empiricus portrays the Pyrrhonian sceptics in two radically different ways. On the one hand, he describes them as inquirers or examiners, and insists that what distinguishes them from all the other philosophical schools is their persistent engagement in inquiry. On the other hand, he insists that the main feature of Pyrrhonian attitude is suspension of judgement about everything. Many have argued that a consistent account of Sextan scepticism as both investigative and suspensive is not possible. The main obstacle to (...) characterizing Pyrrhonism as both investigative and suspensive is the fact that it seems that the mature sceptics, after they have suspended judgement and thus reached tranquillity, have no motivation for further inquiry. Any inquiry they seem to be interested in after they have suspended judgement is the refutation of beliefs needed for maintaining tranquillity. I try to show that the mature sceptics' removal of distress does not ipso facto mean removal of the desire for knowledge. This is because distress is not just a matter of unsatisfied desire, but of belief that one of the opposed appearances must be true, or, more generally, of belief that the truth is the only worthwhile epistemic goal. Having abandoned this belief, the sceptics can still engage in philosophical inquiries. This is because Sextus does not assume that philosophy is the search for truth: it is so only for the dogmatists. In a more general sense, applicable to the sceptics as well, philosophy is just an inquiry into certain things, and for the sceptics, its epistemic goal is still open. (shrink)

This article is an investigation of the nature of suspension of judgement as it is conceived by Sextus Empiricus. I carry out this investigation by examining what I take to be Sextus’ most pertinent remarks on the topic and by considering them in the context of contemporary philosophical work on the nature of suspension. Against the more frequently encountered idea that Sextus is operating with a privative conception of suspension, I argue that Sextus instead has a metacognitive account of suspension, (...) whereby suspending constitutively involves acknowledging that one is not in a position to tell whether or not p.

This chapter considers the encounter of skepticism with the Kantian and post-Kantian philosophical enterprise and focuses on the intriguing feature whereby it is assimilated into this enterprise. In this period, skepticism becomes interchangeable with its other, which helps understand the proliferation of many kinds of views under its name and which forms the background for transforming skepticism into an anonymous, routine practice of raising objections and counter-objections to one’s own view. German philosophers of this era counterpose skepticism to dogmatism and (...) criticism, ancient to modern skepticism, and, importantly, conceptualize the transitions from one form to another, which forms the conceptual matrix in which new disciplinary forms, such as psychology, anthropology, and historicism contend for cultural-intellectual standing beside philosophy. I present this assimilationist trajectory by reviewing three well-known moments of this encounter of skepticism and idealism: (1) Kant’s idealization of skepticism as a floating position amidst various philosophical positions through the dialectic, polemics, systematics, and history of pure reason; (2) Fichte’s schematic conception of skepticism as a dispute of systems in the early Wissenschaftslehre following his review of the skeptic G. E. Schulze’s attacks on Critical philosophy; (3) Hegel’s historicizing conception of skepticism in the context of differences between subjective idealism and speculative thought and his early Jena review of another work by the same skeptic Schulze.

Ancient Greek philosophical schools are said to share a common structure in their ethical theories which is characterized by a eudaimonistic teleology based in an understanding of human nature. At first glance, the skepticism of Sextus Empiricus as described in the Outlines of Pyrrhonism seems to fit into this model insofar as he describes the end of the skeptic as ataraxia, a common account of the expression of human happiness. I argue that this is a misunderstanding of Sextus’s philosophy for (...) several reasons. “The end of skepticism” cannot be eudaimonistic or teleological in the way that other ancient ethical theories are typically understood; moreover, ataraxia is not an end derived from a theory about human nature. For these reasons, the skeptical way of life is radically different than the ethical theories proposed by other schools. I argue that this difference is a result of the character of the skeptical enterprise which involves the implicit rejection of norms in both the epistemological and the ethical spheres. (shrink)

The question of whether the Pyrrhonist adheres to certain logical principles, criteria of justification, and inference rules is of central importance for the study of Pyrrhonism. Its significance lies in that, whereas the Pyrrhonist describes his philosophical stance and argues against the Dogmatists by means of what may be considered a rational discourse, adherence to any such principles, criteria, and rules does not seem compatible with the radical character of his skepticism. Hence, if the Pyrrhonist does endorse them, one must (...) conclude that he is inconsistent in his outlook. Despite its import, the question under consideration has not received, in the vast literature on Pyrrhonism of the past three decades, all the attention it deserves. In the present paper, I do not propose to provide a full examination of the Pyrrhonist’s attitude towards rationality, but to focus on the question of whether he endorses the law of non-contradiction (LNC). However, I will also briefly tackle the question of the Pyrrhonist’s outlook on both the canons of rational justification at work in the so-called Five Modes of Agrippa and the logical rules of inference. In addition, given that the LNC is deemed a fundamental principle of rationality, determining the Pyrrhonist’s attitude towards it will allow us to understand his general attitude towards rationality.

This is a defense of Pyrrhonian skepticism against the charge that the suspension of judgment based on equipollence is vitiated by the assent given to the equipollence in question. The apparent conflict has a conceptual side as well as a practical side, examined here as separate challenges with a section devoted to each. The conceptual challenge is that the skeptical transition from an equipollence of arguments to a suspension of judgment is undermined either by a logical contradiction or by an (...) epistemic inconsistency, perhaps by both, because the determination and affirmation of equipollence is itself a judgment of sorts, one that is not suspended. The practical challenge is that, independently of any conceptual confusion or contradiction, suspending judgment in reaction to equipollence evinces doxastic commitment to equipollence, if only because human beings are not capable of making assessments requiring rational determination without believing the corresponding premises and conclusions to be true. The two analytic sections addressing these challenges are preceded by two prefatory sections, one laying out the epistemic process, the other reviewing the evidentiary context. The response from the conceptual perspective is that the suspension of judgment based on equipollence is not a reasoned conclusion adopted as the truth of the matter but a natural reaction to an impression left by the apparently equal weight of opposing arguments. The response from the practical perspective is that the acknowledgment of equipollence is not just an affirmation of the equal weight of arguments but also an admission of inability to decide, suggesting that any assent, express or implied, is thrust upon the Pyrrhonist in a state of epistemic paralysis affecting the will and the intellect on the matter being investigated. This just leaves a deep disagreement, if any, regarding whether equipollence is an inference based on discursive activity or an impression coming from passive receptivity. But this, even if resolved in favor of the critic (which it need not and ought not be), is not the same as confusion or inconsistency on the part of the Pyrrhonist, the demonstration of which is the primary aim of this paper.
