Evidentialism says that a subject S’s justification is entirely determined by S’s evidence. The plausibility of evidentialism depends on what kind of entities constitute a subject S’s evidence and what one takes the support relation to consist in. Conee and Feldman’s mainstream evidentialism incorporates a psychologist answer to and an explanationist answer to. ME naturally accommodates perceptual justification. However, it does not accommodate intuitive cases of inferential justification. In the second part of the paper, I consider and reject a reply (...) based on a refined explanationist theory of the support relation proposed by K McCain. (shrink)

In this paper, I defend the view that only practical reasons are normative reasons for belief. This requires viewing beliefs as the predictable results of our actions. I will show how this fits with our intuitions about mental autonomy. The remainder of the paper consists in a defense against a series of objections that may be expected against this position. The paper concludes with a metaphilosophical explanation about our conflicting intuitions regarding the normativity of rationality.

Phenomenal conservatism is a popular theory of epistemic justification. Despite its popularity and the fact that some think that phenomenal conservatism can provide a complete account of justification, it faces several challenges. Among these challenges are the need to provide accounts of defeaters and inferential justification. Fortunately, there is hope for phenomenal conservatism. Explanationism, the view on which justification is a matter of explanatory considerations, can help phenomenal conservatism with both of these challenges. The resulting view is one that respects (...) the internalist character of phenomenal conservatism and its motivating intuitions while providing an intuitive and elegant account of both inferential justification and the justificatory impact of defeaters.

In this paper, I provide a novel explanationist framework for thinking about peer disagreement that solves many of the puzzles regarding disagreement that have troubled epistemologists over the last two decades. Explanationism is the view that a subject is justified in believing a proposition just in case that proposition is part of the best explanation of that subject’s total evidence. Applying explanationism to the problem of peer disagreement yields the following principle: in cases of peer disagreement, the thing that the (...) subjects ought to believe is the thing that is the best explanation of their total evidence, where part of their evidence is the fact that they happen to find themselves in disagreement with an epistemic peer. In what follows, I show how to understand and apply this core idea. (shrink)

In a recent paper, Appley and Stoutenburg present two new objections to Explanationist Evidentialism : the Regress Objection and the Threshold Objection. In this paper, I develop a version of EE that is independently plausible and empirically grounded, and show that it can meet Appley and Stoutenburg’s objections.

We offer a general framework for theorizing about the structure of knowledge and belief in terms of the comparative normality of situations compatible with one’s evidence. The guiding idea is that, if a possibility is sufficiently less normal than one’s actual situation, then one can know that that possibility does not obtain. This explains how people can have inductive knowledge that goes beyond what is strictly entailed by their evidence. We motivate the framework by showing how it illuminates knowledge about (...) the future, knowledge of lawful regularities, knowledge about parameters measured using imperfect instruments, the connection between knowledge, belief, and probability, and the dynamics of knowledge and belief in response to new evidence.

When is a person justified in believing a proposition? In this paper, I defend a view according to which a person is justified in believing a proposition just in case the person’s evidence sufficiently supports the proposition and the person responsibly acquired and sustained the evidence that supports the proposition. This view overcomes a deficiency in a prominent theory of epistemic justification. As championed by Earl Conee and Richard Feldman, Evidentialism is a theory subject to counterexamples at the hands of (...) cases involving epistemic irresponsibility. I critically discuss such a case as put forward by Jason Baehr. After providing an argument that clarifies why the case is problematic for Evidentialism, I defend my argument from a response by Earl Conee. Then I develop a theory of epistemic justification capable of handling cases involving epistemic irresponsibility, and I defend this theory from evidentialist objections. (shrink)

This paper continues a recent exchange in this journal concerning explanationist accounts of epistemic justification. In the first paper in this exchange, Byerly argues that explanationist views judge that certain beliefs about the future are unjustified when in fact they are justified. In the second paper, McCain defends a version of explanationism which he argues escapes Byerly’s criticism. Here we contribute to this exchange in two ways. In the first section, we argue that McCain’s defense of explanationism against Byerly’s objection (...) is unsuccessful. Then, in the second section, we develop an independent objection to explanationism from a different direction. If our arguments in each section are sound, then not only do explanationist accounts of epistemic justification judge beliefs that are justified to be unjustified, but they judge beliefs that are unjustified to be justified. Explanationism faces problems on both sides. (shrink)

This paper discusses the ability of explanationist theories of epistemic justification to account for the justification we have for holding beliefs about the future. McCain’s explanationist account of the relation of evidential support is supposedly in a better position than other theories of this type to correctly handle cases involving beliefs about the future. However, the results delivered by this account have been questioned by Byerly and Martin. This paper argues that McCain’s account is, in fact, able to deliver plausible (...) results in cases involving such beliefs and that explanationism, if properly articulated, is illuminating with respect to the justification we have for holding such beliefs, as it manages to correctly distinguish evidence that only supports believing probabilistic claims about the future from evidence that is sufficient to believe that a particular event will happen.

This article examines Smith’s recent treatment of the problem of statistical evidence and the conception of epistemic justification that he puts forward. Two possible solutions to the problem of statistical evidence that result from his analysis of cases involving a contrast between statistical and individual evidence are considered. The solution resulting from Smith’s conception of epistemic justification is shown to be inferior to the solution calling for an explanationist conception of epistemic justification. As a result, Smith’s analysis of cases illustrating (...) the problem of statistical evidence, given his own standards of theory choice, is shown to support an explanationist conception of epistemic justification as an alternative to the probabilistic conception that he urges us to reject.

After a period of inactivity, interest in explanationism as a thesis about the nature of epistemic justification has been renewed. Poston and McCain have both recently offered versions of explanationist evidentialism. In this paper, we pose two objections to explanationist evidentialism. First, explanationist evidentialism fails to state a sufficient condition for justification. Second, explanationist evidentialism implies a vicious regress.

Evidentialism is an internalist view (or family of views) about epistemic justification saying that a subject s’s epistemic justification entirely depends on the evidence at her disposal. In order to distil a complete theory of epistemic justification from this general principle it is necessary to answer three main questions. What kind of entities constitute a subject’s evidence? What does it take for a piece of evidence E to support a proposition P? What does it take for a subject s to (...) possess E? In this entry I describe the main answers defended in the literature in response to these three questions, and critically discuss the main objections that have been raised against evidentialism, both at a general level and as targeting more specific variants of it.
