One of the main goals of epistemologists is to provide a substantive and explanatory account of the conditions under which a belief has some desirable epistemic status (typically, justification or knowledge). According to the reliabilist approach to epistemology, any adequate account will need to mention the reliability of the process responsible for the belief, or truth-conducive considerations more generally. Historically, one major motivation for reliabilism—and one source of its enduring interest—is its naturalistic potential. According to reliabilists, epistemic properties can be (...) explained in terms of reliability, which in turn can be understood without reference to any unreduced epistemic notions, such as evidence or knowledge. This article begins by surveying some of the main forms of reliabilism, concentrating on process reliabilism as a theory of justification. It proceeds to review some of the main objections to reliabilism, and some of the responses that have been offered on the reliabilist’s behalf. After canvassing some recent developments in reliabilist epistemology, the article concludes by considering various cousins and spin-offs of reliabilist epistemology, including virtue reliabilism and various evidentialist-reliabilist hybrids.

The generality problem is one of the most pressing challenges for reliabilism. The problem begins with this question: of all the process types exemplified by a given process token, which types are the relevant ones for determining whether the resultant belief counts as knowledge? As philosophers like Earl Conee and Richard Feldman have argued, extant responses to the generality problem have failed, and it looks as if no solution is forthcoming. In this paper, I present a new response to the (...) generality problem that illuminates the nature of knowledge-enabling reliability. My response builds upon the insights of Juan Comesaña’s well-founded solution to the generality problem, according to which relevant types are content–evidence pairs, i.e., descriptions of both the target belief’s content and the evidence on which the belief was based. While most responses to the generality problem, including Comesaña’s, only posit one relevant type for any given process token, I argue that knowledge-enabling reliability requires a process token to be reliable with respect to multiple content–evidence pairs, each with varying degrees of descriptive specificity. I call this solution multi-type evidential reliabilism. After offering a clear formulation of MTE, I conclude by arguing that MTE is sufficiently informative to rebut Conee and Feldman’s generality problem objection to a reliability condition on knowledge.

In “A well-founded solution to the generality problem,” Comesaña argues, inter alia, for three main claims. One is what I call the unavoidability claim: Any adequate epistemological theory needs to appeal, either implicitly or explicitly, to the notion of a belief’s being based on certain evidence. Another is what I call the legitimacy claim: It is perfectly legitimate to appeal to the basing relation in solving a problem for an epistemological theory. According to Comesaña, the legitimacy claim follows straightforwardly from (...) the unavoidability claim. The third one is what I call the basing solution claim: An appeal to the notion of basing relation is all we need to solve the generality problem for (process) reliabilism. In this paper, I will argue that the unavoidability claim and the basing solution claim are false and that the legitimacy claim might be true only in a qualified sense. (shrink)

Hume's epistemological legacy is often perceived as a predominantly negative sceptical one. His infamous problem of induction continues to perplex philosophers to this day, and many of his sceptical worries maintain their interest in contemporary eyes (e.g. with regard to reason, the senses, substance, causation). Yet Hume's positive epistemological contributions also hold significance for philosophy in this day and age. In this paper, I aim to situate Hume's epistemology in a more contemporary context, particularly with regard to the theme of (...) reliabilism that runs throughout this epistemology. This will take the shape of examining correspondences and contrasts between Hume's epistemologies in the Treatise and Enquiry and reliabilism, as well as an examination of how Hume's framework might handle some major challenges for reliabilist epistemologies. In particular, I argue that that while Hume is tempted to an epistemology that is intimately tied to truth in the Treatise, he backs away when confronted with the excesses of scepticism in the conclusion of Book 1, and winds up with an epistemology most similar to the contemporary epistemological frameworks of dogmatism and phenomenal conservatism. Yet, largely because of his reliance on the passions (a respect in which he diverges from these two contemporary frameworks), the epistemology of the Treatise remains crucially dissociated from truth. Meanwhile, in the first Enquiry, he proceeds to develop a two-tiered epistemological framework that first accords all our justification with default authority, and then founds all-things-considered epistemic justification on our evidence for the reliability of our faculties. The first tier most resembles the contemporary epistemological framework of conservatism, while the second tier most closely resembles approved-list reliabilism. In this, a clear reliabilist thread runs through the epistemology of the Enquiry. I will also argue that although Hume did not appear to fully appreciate one of the most significant challenges for reliabilism-that is, the generality problem-his philosophical framework nevertheless contains the beginnings of a response to it.
