This entry is composed of three sections. In §1, we survey debates about what structural rationality is, including the emergence of the concept in the contemporary literature, its key characteristics, its relationship to substantive rationality, its paradigm instances, and the questions of whether these instances are unified and, if so, how. In §2, we turn to the debate about structural requirements of rationality – including controversies about whether they are “wide-scope” or “narrow-scope”, synchronic or diachronic, and whether they govern processes (...) or states; as well as examining various forms of skepticism about structural requirements of rationality. In §3, we turn to the debate about the normative significance of structural rationality, surveying central challenges for the view that structural rationality is normatively significant and the theoretical options that arise in light of these challenges.

Both actions and beliefs are subject to normative evaluation as rational or irrational. As such, we might expect there to be some general, unified story about what makes them rational. However, orthodox approaches suggest that the rationality of action is determined by practical considerations, while the rationality of belief is determined by properly epistemic considerations. This apparent disunity leads some, like Rinard (2019), to reject orthodox theories of the rationality of belief in favor of pragmatism. In this paper, I argue (...) we should reject pragmatist approaches to unifying the rationality of action and belief. Instead, I argue, we should embrace a correctness‐based view of rationality, on which rationality is fundamentally about getting things correct as best we can, given our epistemic limitations. On such a view, the facts about rational action and belief are a function of the facts about correct action and belief. I contend that the apparent disunity of orthodox theories is created by the fact that action and belief have different correctness conditions. Nevertheless, on the correctness‐based view, this disunity is merely apparent. This renders pragmatism's revisionary implications for the rationality of belief unnecessary to take on in order unify it with the rationality of action. (shrink)

The term ‘coherence’ (and its antonym ‘incoherence’) is used in a bewildering variety of ways in epistemology (and in philosophy more broadly). This entry attempts to bring some discipline to uses of the term by offering a taxonomy of notions of coherence (and incoherence), and then surveying which of the resulting notions is (or should be) at work in the various different contexts in which it is deployed.
