This paper explains the nature and role of common sense in Reid and uses the exposition to answer some of Reid's critics. The key to defending Reid is to distinguish between two kinds of priority that common sense beliefs are supposed to enjoy. Common sense beliefs enjoy epistemological priority in that they constitute a foundation for knowledge; i.e. they have evidential status without being grounded in further evidence themselves. Common sense beliefs enjoy methodological priority in that they constrain philosophical theory: they serve as pre-theoretical commitments that philosophical theories ought to respect in the absence of good reasons for rejecting them.

An adequate account of testimonial knowledge in general explains how religious knowledge can be grounded in testimony, and even in the context of conflicting testimonial traditions. Three emerging trends in epistemology help to make that case. The first is to make a distinction between two projects of epistemology: “the project of explanation” and “the project of vindication.” The second is to emphasize a distinction between knowledge and understanding. The third is to ask what role the concept of knowledge plays in our conceptual-linguistic economy. Each of these trends, it is argued, helps us to make progress in the epistemology of testimony, and by application in the epistemology of religious belief.

Alvin Plantinga charges classical foundationalism with self-referential incoherence, meaning that that doctrine employs criteria for rationally acceptable propositions which exclude the criteria themselves. More specifically, the charge is that the criteria are neither properly basic nor supported by properly basic propositions. In section 1 the doctrine of classical foundationalism is briefly explained. In section 2, a defense against Plantinga's objection is provided showing how the foundationalist can provide arguments which ground the criteria in question in properly basic propositions.

In ”Virtues in Epistemology,” John Greco presents and evaluates two main notions of intellectual virtue. The first concerns Ernest Sosa's development of this concept as a disposition to grasp truth and avoid falsehood. Greco contrasts this with moral models of intellectual virtue that include a motivational component in their definition, namely a desire for truth. Instead, Greco argues that a minimalist reliabilist account of intellectual virtue “in which the virtues are conceived as reliable cognitive abilities or powers,” can be illuminating in an account of knowledge. He sets out to support this on the grounds that his approach to intellectual virtue can adequately address three major problems on the theory of knowledge: Humean skepticism, the Gettier problem, and the problem of showing that knowledge is more valuable than mere true belief.

In section one the deontological (or responsibilist) conception of justification is discussed and explained. In section two, arguments are put forward in order to derive the most plausible version of perspectival internalism, or the position that epistemic justification is a function of factors internal to the believer's cognitive perspective. The two most common considerations put forward in favor of perspectival internalism are discussed. These are the responsibilist conception of justification, and the intuition that two believers with like beliefs and experiences are equally justified in their like beliefs. In section three it is argued that perspectival internalism is false, and that in fact the position is not supported by a responsibilist conception of justification. Section four explicates two other forms of internalism, which are rejected for reasons similar to those presented against perspectival internalism. In section five, an internalist theory of justification is defended which is supported by a responsibilist conception of justification. Roughly stated, the position is that justified belief is belief which arises from the use of correct rules of reasoning. The idea of correctness is explicated, and the position is distinguished from others which are similar to it.

I review a familiar skeptical argument from Hume, and conclude that it requires us to accept that there is no necessary relation between beliefs about the world and their evidential grounds; that is, there is no logical or quasi-logical relation between empirical beliefs and their grounds, such that their grounds entail them, or even make them probable. I then argue that generic reliabilism can accommodate this fact about evidential grounds in a non-skeptical way. According to reliabilism, the grounds for our beliefs constitute good evidence so long as they are contingently reliable. Next I argue that agent reliabilism successfully addresses two related problems for other versions of reliabilism: the fact that beliefs can be reliably formed by accident, and the need for subjective justification. Finally, I explain why agent reliabilism is properly conceived as a version of virtue epistemology.

The second major thesis of the book follows closely on the first: that the analysis of skeptical arguments is philosophically useful and important, and should therefore have a central role in the methodology of philosophy, and especially in the methodology of epistemology. A close analysis of skeptical arguments highlights our pre-theoretically plausible, but ultimately mistaken, assumptions about the nature of knowledge and evidence. Skeptical arguments are powerful just because their assumptions are so plausible pre-theoretically. But the arguments show us where those assumptions lead, and thereby force us to rethink those assumptions. On this view, skeptical arguments constitute theoretical problems rather than practical problems. There is no “practical” or “existential” problem of skepticism. Rather, skeptical arguments show us that we need to rethink our assumptions about knowledge and evidence, and replace them with something better.

A number of virtue epistemologists endorse the following thesis: Knowledge is true belief resulting from intellectual virtue, where Ss true belief results from intellectual virtue just in case S believes the truth because S is intellectually virtuous. This thesis commits one to a sort of contextualism about knowledge attributions. This is because, in general, sentences of the form X occurred because Y occurred require a contextualist treatment. This sort of contextualism is contrasted with more familiar versions. It is argued that the position: (a) yields a better solution to the lottery problem, and (b) may be grounded in a more general theory of virtue and credit.

The claim that knowledge is a kind of success from ability has great theoretical power: it explains the nature of epistemic normativity, why knowledge is incompatible with luck, and why knowledge is more valuable than mere true belief. This paper addresses objections to the view by wedding it with two additional ideas: that intellectual abilities display a certain structure, and that the concept of knowledge functions to flag good information, and good sources of information, for use in practical reasoning.

In this paper I will take it for granted that Zagzebski's position articulates a broadly Catholic perspective, and that Plantinga's position accurately represents a broadly Calvinist one. But I will argue that so construed, the Catholic and the Calvinist are much closer than Zagzebski implies: both views are person-based in an important sense of that term; both are internalist on Zagzebski's usage and externalist on the standard usage; and Plantinga's position is consistent with the social elements that Zagzebski stresses in her view. In the second part of the paper I will identify what I think is the real issue between Zagzebski and Plantinga. Namely, Zagzebski thinks that knowledge requires epistemic responsibility, in the sense that instances of knowledge must be appropriately praiseworthy. Plantinga thinks that no such condition is required for knowledge or warranted belief. I will argue that on this issue Zagzebski is right, and that her virtue approach gives us resources for seeing why. Finally, I will look at the consequences for religious knowledge. Here I will argue that the consequences are minimal. Even if knowledge requires responsibility, Plantinga can still make a good case that religious belief is properly basic. And even if religious belief is properly basic, natural theology can still have an important role in the justification of religious belief.

This paper addresses two worries that might be raised about contextualism in epistemology and that carry over to its moral analogues: that contextualism robs epistemology (and moral theory) of a proper subject-matter, and that contextualism robs knowledge claims (and moral claims) of their objectivity. Two theses are defended: (1) that these worries are appropriately directed at interestdependent theories in general rather than at contextualism in particular, and (2) that the two worries are over-stated in any case. Finally, the paper offers some considerations in favour of attributor contextualism over 'subject-sensitive invariantism', both in epistemology and in moral theory. But here we note an interesting result: the very considerations that support contextualism as a semantic thesis, threaten to rob that position of its anti-sceptical force.
