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.

An objection that has been raised to the conciliatory stance on the epistemic significance of peer disagreement known as the Equal Weight View is that it is self-defeating, self-undermining, or self-refuting. The proponent of that view claims that equal weight should be given to all the parties to a peer dispute. Hence, if one of his epistemic peers defends the opposite view, he is required to give equal weight to the two rival views, thereby undermining his confidence in the correctness (...) of the Equal Weight View. It seems that the same objection could be leveled against those who claim to suspend judgment in the face of pervasive unresolvable disagreements, as do the Pyrrhonian skeptics. In this paper, I explore the kind of response to the objection that could be offered from a neo-Pyrrhonian perspective, with the aim of better understanding the intriguing character of Pyrrhonian skepticism.

It is a common intuition that at least in some cases disagreement has skeptical consequences: the participants are not justified in persisting in their beliefs. I will argue that the currently popular non-dialectical and individualistic accounts of justification, such as evidentialism and reliabilism, cannot explain this intuition and defend the dialectical conception of justification that can explain it. I will also argue that this sort of justification is a necessary condition of knowledge by relying on Craig's genealogy of the concept (...) of knowledge. I will then respond to the accusation that the dialectical conception leads to radical skepticism. My response is partly concessive. It does lead to skepticism in areas where controversy prevails, such as philosophy, politics and religion, but this sort of skepticism is quite intuitive. Finally, I deal with the objection that my defense of skepticism about philosophy is self-refuting. (shrink)

Ignorance can excuse otherwise blameworthy action, but only if the ignorance itself is blameless. One way to avoid culpable ignorance is to pay attention when epistemic peers disagree. Expressed disagreements place an obligation on the agent to pay attention when an interlocutor disagrees, or risk culpable ignorance for which they might later be found blameworthy. Silence, on the other hand, is typically taken as assent. But in cases of suppressed disagreement, the silenced interlocutor has information that could save the agent (...) from ignorance in scenarios where that ignorance might lead to harmful action, and silence does not actually indicate assent. The problem is further complicated because the agent might not be aware of the fact that a silenced interlocutor has information that could prevent ignorance, and consequent harmful action. In this paper, I provide a new account of excuses from ignorance in situations of suppressed disagreement. I do this in the context of two cases; Kelly’s hypothetical case of the Tyrannical Dictator, and the real-world case of former South African President Thabo Mbeki and his AIDS denialist policies in the late 1990s and early 2000s.

This article examines the central epistemological issues tied to the recognition of disagreement.

In this introductory chapter, I first offer an overview of the two themes addressed in the present collection - namely, disagreement and skepticism - and their connection, then present the purpose and content of the volume.

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.

Recent discussions about the ancient sources of skepticism have provided new elements to evaluate the scope of the Pyrrhonian proposal and to differentiate it from modern skeptical manifestations. This, in turn, has allowed us to explore the affinities between the ideas that Sextus Empiricus exposed in his Outlines of Pyrrhonism and the ideas that Wittgenstein presented in On Certainty. My purpose is to evaluate the scope of these affnities from the place that both authors give to the problem of disagreement.
