This book presents an original discussion and analysis of epistemic peer disagreement. It reviews a wide range of cases from the literature, and extends the definition of epistemic peerhood with respect to the current one, to account for the actual variability found in real-world examples. The book offers a number of arguments supporting the variability in the nature and in the range of disagreements, and outlines the main benefits of disagreement among peers i.e. what the author calls the benefits to (...) inquiry argument.

While epistemologists have long debated what it takes for beliefs to be justified, they've devoted much less collective attention to the question of what it takes for beliefs to be excused, and how excuses differ from justifications. This stands in contrast to the state of affairs in legal scholarship, where the contrast between justifications and excuses is a standard topic in introductory criminal law textbooks. My goal in this paper is to extract some lessons from legal theory for epistemologists seeking (...) to distinguish epistemic justifications from epistemic excuses. First, I'll provide a brief overview of appeals to the justification/excuse distinction in epistemology, focusing on the internalism/externalism debate. Then, I'll identify some choice points in legal theory for how to think about the function of the justification/excuse distinction, and will in turn correspond to analogous choice points in epistemology. Ultimately, I'll argue that depending on which way we go at some crucial junctures, we can motivate either a traditional, non‐factive, internalist conception of justification, or a purely factive one where truth is all that's required for a belief to be justified. But there's no clear path, via legal theory, to view that only beliefs that amount to knowledge are justified. (shrink)

There seem to be cases where A believes p, and B believes not-p, but neither makes a mistake. This is known as faultless disagreement. According to the epistemic account, in at least some cases of faultless disagreement either A or B must believe something false, and the disagreement is faultless in the sense that each follows the epistemic norm. Recently, philosophers have raised various objections to this account. In this paper, I propose a new version of the epistemic account and (...) show how it can handle those objections. (shrink)

Far from considering the phenomenon of disagreement across the board, the peer debate in epistemology solely focuses on cases of disagreements that are at least assumed to be genuine. What counts as a genuine disagreement is most of the times kept on the level of a pre-theoretical intuition according to which the peers disagree insofar as they hold incompatible doxastic attitudes with respect to a proposition P (King, 2012). Yet, the pre-theoretical intuition yields the wrong verdict when the bone of (...) contention is a proposition whose truth is relativized. In order to avoid these counter-intuitive results, the peer debate needs to replace the pre-theoretical intuition of genuine disagreement with a full-fledged account of it. In this essay I firstly put forth a possible candidate for the role coming from an ongoing discussion in philosophy of language. Then, I assess how well such an account fares in both an outright and a credal model of belief. (shrink)

I hope to show that each of 1, 2, and 3 are plausible, yet we can derive 4: 1. It is epistemically permissible to believe that our preferred views in multi-proposition disputes are true, or at least more likely true than not. 2. If it is epistemically permissible to believe that our preferred views in multi-proposition disputes are true, or at least more likely true than not, then it is epistemically permissible for us to believe that we are über epistemic (...) superiors to our disagreeing colleagues in multi-proposition disputes. 3. It is not epistemically permissible to believe that we are über epistemic superiors to our disagreeing colleagues in multi-proposition disputes. 4. At least one of 1, 2, or 3, is false. (shrink)

Throughout history, both philosophers and non-philosophers have doubted that philosophical positions qua philosophical positions are justified and that philosophy is a rational enterprise. Today, such doubts are grouped under the term “Metaphilosophical Skepticism”. Nicholas Rescher, in his book Strife of Systems, includes Kant among the proponents of this kind of skepticism. I want to argue that while Rescher is wrong, Kant has con­tributed to a new version of such skepticism. In the first step, I characterize the basic idea of metaphilosophical (...) skepticism in more detail and identify a version of this idea, which I call “Second-Stage-Skepticism” and on which I will focus. In the following part, I reconstruct Rescher’s reading of Second-Stage-Skepticism as well as his reasons for considering Kant to represent this version. My main claim in this part will be that there is no reading of the mentioned basic idea that makes Rescher’s view reasonable. In the third step, I introduce a newer form of metaphilosophical skepticism — “Third-Stage Skepticism” — and conjecture that this form can be seen as inspired by Kant’s thought on philosophical diversity. Finally, I point out a way to reject this newer form. (shrink)

In recent debates over permissivism and uniqueness—two theses concerning the relationship between evidence and epistemic rationality—some philosophers have claimed that permissivism has an intuitive advantage over uniqueness. I examine the cases alleged to intuitively motivate permissivism and suggest they do not provide prima facie support for permissivism. I conclude by explaining how my discussion bears on whether permissivism can defeat skeptical arguments based on recognized peer disagreement and the historical contingency of our beliefs.

The paper argues that adopting a form of skepticism, Skeptical-Dogmatism, that recommends disbelieving each philosophical position in many multi-proposition disputes- disputes where there are three or more contrary philosophical views-leads to a higher ratio of true to false beliefs than the ratio of the “average philosopher”. Hence, Skeptical-Dogmatists have more accurate beliefs than the average philosopher. As a corollary, most philosophers would improve the accuracy of their beliefs if they adopted Skeptical-Dogmatism.

Conflict framing is key in political communication. Politicians use conflict framing in their online messages (e.g., criticizing other politicians) and journalists in their political coverage (e.g., reporting on political tensions). Conflicts can take a variety of forms and can provoke different reactions. However, the literature still lacks a systematic and theoretically-grounded conceptual framework that accounts for the multi-dimensionality of political conflict frames. Based on literature from political epistemology, political communication, and related fields such as psychology, we present four conceptual dimensions (...) of political conflicts: (1) the style (civil/uncivil); (2) the subject (personal/substantive); (3) whether it is about underlying moral/epistemic principles or not (deep/superficial conflict); and (4) whether it concerns a normative or factual issue. Results of a content analysis of newspaper articles and politicians’ tweets confirm the usage of these conflict dimensions in the Netherlands during a non-election period. Interestingly, most of the conflicts are civil, substantive, and do not highlight deep fundamental clashes. In light of the current societal concerns about the lack of respect in political debates and the deepening of our political divides, these findings can be considered encouraging. (shrink)

In my recent book, The Epistemic Benefits of Disagreement, I develop a defense of non-conciliationism, but one that only applies in research contexts: Epistemic benefits are more likely in the offing if inquirers stick to their guns in the face of disagreement. I aim to expand my original account by examining its implications for non-inquiry beliefs. I’m particularly interested in broader worldview disagreements. I want to examine how inquirers should react upon discovering that they disagree about the truth value of (...) a particular proposition because they disagree about a whole host of related propositions. I argue that in many ways, worldview disagreements are easier to work with than disagreement over isolated propositions, in part because it is easier to provide a set of criteria by which to evaluate worldviews. I conclude that my original argument can, at least in part, be successfully expanded to include worldview disagreement. (shrink)

RésuméÉtant donné un ensemble de données D, les tenants de l'unicité épistémique soutiennent qu'une seule réponse doxastique est rationnelle, tandis que les tenants du permissivisme épistémique soutiennent que plusieurs réponses doxastiques peuvent être rationnelles. Comme certains auteurs l'ont signalé, l'un des attraits de la position permissiviste est qu'elle nous permet de comprendre le désaccord philosophique comme un désaccord dans lequel aucune des parties ne commet de faute rationnelle, et donc de respecter le statut épistémique de chacune d'elles. Je soutiens au (...) contraire que la position permissiviste ne parvient pas à offrir un tel avantage dans de nombreux désaccords philosophiques. (shrink)

Political liberalism, or public reason liberalism, has taken a decisive turn towards the Convergence Conception of public justification and away from the orthodox Consensus Conception. Convergence theorists argue that public justification should be understood as all reasonable people having some conclusive reason to endorse coercively enforced moral rules that are issue and context specific. They argue for this on the basis that, given the nature of deep moral and political disagreement, only the Convergence Conception can show reasonable people how to (...) achieve a stable political order. I argue however that the Convergence Conception faces the Verbal Agreement Objection which puts pressure on its claims to show people how to maintain a political order. This is because at its core it involves a tension between its account of the nature of the agreements that constitute public justification and the objects of those agreements that make it highly sensitive to context changes.
