Earl Conee and Richard Feldman have recently argued that the evidential support relation should be understood in terms of explanatory coherence: roughly, one's evidence supports a proposition if and only if that proposition is part of the best available explanation of the evidence (2008). Their thesis has been criticized through alleged counterexamples, perhaps the most important of which are cases where a subject has a justified belief about the future (Byerly 2013; Byerly and Martin forthcoming). Kevin McCain has defended the thesis against Byerly's counterexample (2013, 2014a). I argue that McCain's defense is inadequate before pointing toward a more promising solution for explanationism. The Byerly–McCain exchange is important because it casts light on the difficult issues of the standards for justification and the nature of epistemic support. Furthermore, McCain's defense of explanationism about epistemic support represents an important recent development of the burgeoning explanationist program in epistemology and philosophy of science.

Solidarity is supposed to facilitate collective action. We argue that it can also help overcome false consciousness. Groups practice ‘epistemic solidarity’ if they pool information about what is in their true interest and how to vote accordingly. The more numerous ‘Masses’ can in this way overcome the ‘Elites,’ but only if they are minimally confident with whom they share the same interests and only if they are (perhaps only just) better-than-random in voting for the alternative that promotes their interests. Being more cohesive and more competent than the Masses, the Elites can employ the same strategy perhaps all the more effectively. But so long as the Masses practice epistemic solidarity they will almost always win, whether or not the Elites do. By enriching the traditional framework of the Condorcet Jury Theorem with group-specific standards of correctness, we investigate how groups can organize to support the alternatives truly in their interests.

This paper concerns the relationship between epistemology and radically extended cognition. Radically extended cognition (REC) – as advanced by Andy Clark and David Chalmers – is cognition that is partly located outside the biological boundaries of the cognizing subject. Epistemologists have begun to wonder whether REC has any consequences for theories of knowledge. For instance, while Duncan Pritchard suggests that REC might have implications for which virtue epistemology is acceptable, J. Adam Carter wonders whether REC threatens anti-luck epistemology. In this paper, I argue that the possibility of REC has no systematic consequences for theorizing in epistemology. I suggest an alternative relationship between the two: epistemology can play a role in diagnosing cases of REC. Thus, by establishing that entities partially located outside biological boundaries don't play certain epistemic roles, one can establish that they don't play the related cognitive roles either. I conclude the paper by illustrating this last point.

Offering a solution to the skeptical puzzle is a central aim of Nozick's sensitivity account of knowledge. It is well-known that this account faces serious problems. However, because of its simplicity and its explanatory power, the sensitivity principle has remained attractive and has been subject to numerous modifications, leading to a ‘second wave’ of sensitivity accounts. I will object to these accounts, arguing that sensitivity accounts of knowledge face two problems. First, they deliver a far too heterogeneous picture of higher-level beliefs about the truth or falsity of one's own beliefs. Second, this problem carries over to bootstrapping and Moorean reasoning. Some beliefs formed via bootstrapping or Moorean reasoning are insensitive, but some closely related beliefs in even stronger propositions are sensitive. These heterogeneous results regarding sensitivity do not fit with our intuitions about bootstrapping and Moorean reasoning. Thus, neither Nozick's sensitivity account of knowledge nor any of its modified versions can provide the basis for an argument that bootstrapping and Moorean reasoning are flawed or for an explanation why they seem to be flawed.

In Democratic Reason, Hélène Landemore has built a case for the epistemic virtues of inclusive deliberative democracy based on the cognitive diversity of the group engaged in making collective decisions. She supports her thesis by appealing to the Diversity Trumps Ability Theorem of Lu Hong and Scott Page. This theorem is quite technical and the informal statements of it aimed at democratic theorists are inaccurate, which has resulted in some misguided critiques of the theorem's applicability to democratic politics. This paper provides an exposition of the Diversity Trumps Ability Theorem that does not sacrifice precision for accessibility. It also shows that it is not possible to satisfy the assumptions of this theorem when there are only two options. Thus, the Diversity Trumps Ability Theorem cannot provide support for the epistemic virtues of inclusive democratic deliberation for binary collective decisions.
