Some disagreements concern our most fundamental beliefs, principles, values, or worldviews, such as those about the existence of God, society and politics, or the trustworthiness of science. These are ‘deep disagreements’. But what exactly are deep disagreements? This paper critically overviews theories of deep disagreement. It does three things. First, it explains the differences between deep and other kinds of disagreement, including peer, persistent, and widespread disagreement. Second, it critically overviews two mainstream theories of deep disagreement, the Wittgensteinian account and (...) the Fundamental Epistemic Principle account, before introducing a Hybrid account. Finally, it explores the notion that deep disagreements can be deeper than others. (shrink)

Appeals to “being on the right side of history” or accusations of being on the wrong side of history are increasingly common on social media, in the media proper, and in the rhetoric of politics. One might well wonder, though, what the value is of invoking history in this manner. Is declaring who is on what side of history merely dramatic shorthand for one's being right and one's opponents wrong? Or is there something more to it than that? In this (...) paper, I argue that an appeal to being on the right side of history is best construed as an invocation of higher-order evidence. I do not deny that there are purely rhetorical, non-evidential uses of the right and wrong side of history, but the phrase can be construed in a more substantive manner. I use work on virtual epistemic elections to model these appeals to history. Zeroing in on the kind of higher-order evidence invoked helps us clarify the criterion for better or worse, more or less convincing appeals to it. (shrink)

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

The article addresses the question of how should scientific peers revise their beliefs (if at all) upon recognized disagreement. After presenting the basics of peer disagreement in sections 1 and 2, we focus, in section 3, on a concrete case of scientific disagreement, to wit, the dispute over the evidential status of randomized control trials in medical practice. The examination of this case motivates the idea that some scientific disagreements permit a steadfast reaction. In section 4, we support this conclusion (...) by providing a normative argument in the same direction; if we are correct, typical reasons for conciliation are absent in this kind of scientific disagreements.

The conciliationist and steadfast approaches have dominated the conversation in the epistemology of disagreement. In this paper, drawing on Jennifer Lackey’s justificationist approach and the casuistry paradigm in medical ethics, I will develop a more contextual epistemology of political disagreement. On this account, a given political disagreement’s scope, domain, genealogy, and consequence can be helpful for determining whether we should respond to that disagreement at the level of our confidence, beliefs, or with policy. Though some may argue that responding with (...) policy is a practical consideration instead of an epistemic matter, I argue that even policy responses to disagreements have an epistemic dimension to them that we should not ignore.
