This paper contributes to an increasing literature strengthening the connection between epistemic logic and epistemology (Van Benthem, Hendricks). I give a survey of the most important applications of epistemic logic in epistemology. I show how it is used in the history of philosophy (Steiner's reconstruction of Descartes' sceptical argument), in solutions to Moore's paradox (Hintikka), in discussions about the relation between knowledge and belief (Lenzen) and in an alleged refutation of verificationism (Fitch) and I examine an early argument about the (im)possibility of epistemic logic (Hocutt). Subsequently, I deal with interpretive questions about epistemic logic that, although implicitly, already appeared in the first section. I contend that a conception of epistemic logic as a theory of knowledge assertions is incoherent, and I argue that it does not make sense to adopt a normative interpretation of epistemic logic. Finally, I show ways to extend epistemic logic with other branches of philosophical logic so as to make it useful for some epistemological questions. Conditional logics and logics of public announcement are used to understand causal theories of knowledge and versions of reliabilism. Temporal logic helps understand some dynamic aspects of knowledge as well as the verificationist thesis.

A popular form of virtue epistemology—defended by such figures as Ernest Sosa, Linda Zagzebski and John Greco—holds that knowledge can be exclusively understood in virtue-theoretic terms. In particular, it holds that there isn't any need for an additional epistemic condition to deal with the problem posed by knowledge-undermining epistemic luck. It is argued that the sustainability of such a proposal is called into question by the possibility of epistemic twin earth cases. In particular, it is argued that such cases demonstrate the need for virtue-theoretic accounts of knowledge to appeal to an independent epistemic condition which excludes knowledge-undermining epistemic luck.

Operational epistemology is, to a first approximation, the attempt to provide cognitive rules such that one is in principle always in a position to know whether one is complying with them. In Knowledge and its Limits, I argue that the only such rules are trivial ones. In this paper, I generalize the argument in several ways to more thoroughly probabilistic settings, in order to show that it does not merely demonstrate some oddity of the folk epistemological conception of knowledge. Some of the generalizations involve a formal semantic framework for treating epistemic probabilities of epistemic probabilities and expectations of expectations. The upshot is that operational epistemology cannot work, and that knowledge-based epistemology has the right characteristics to avoid its problems.

Jonathan Kvanvig's book, The Value of Knowledge and the Pursuit of Understanding (Kvanvig, 2003), is a wonderful example of doing epistemology in a style that Kvanvig himself has termed "value−driven epistemology." On this approach, one takes questions about epistemic value to be central to theoretical concerns, including the concern to provide an adequate account of knowledge. This approach yields the demand that theories of knowledge must provide, not just an adequate account of the nature of knowledge, but also an account of the value of knowledge. Given the near−universal assumption that knowledge has a special kind of value, this demand seems reasonable, though surprisingly hard to satisfy. Another consequence of this approach to doing epistemology is that certain assumptions about epistemic value, like what sorts of things have it and what sorts of things don't, and where such value comes from, become much more salient to the epistemic enterprise. In his book, Kvanvig challenges the assumption that knowledge has some unique store of epistemic value. And he investigates the matter by asking questions about what the bearers of epistemic value are and where they get it. He concludes, of course, that knowledge as we have come to conceive it in 21st century epistemology has no such special value.

Standard epistemology takes it for granted that there is a special kind of value: epistemic value. This claim does not seem to sit well with act utilitarianism, however, since it holds that only welfare is of real value. I first develop a particularly utilitarian sense of "epistemic value", according to which it is closely analogous to the nature of financial value. I then demonstrate the promise this approach has for two current puzzles in the intersection of epistemology and value theory: first, the problem of why knowledge is better than mere true belief, and second, the relation between epistemic justification and responsibility.

There is a tendency, a bad tendency, to make epistemic agency the central focus of epistemology. In brief, epistemologists have traditionally elevated epistemic agency as the crucial issue to be addressed, and ask all other epistemological questions in light of that issue. This is not surprising given the Cartesian influence on epistemology, but I argue that epistemic agency should not always be the central focus of epistemology. There are times when giving central place to epistemic agency gets in the way of good epistemology. In this paper, I show how one approach to a communitarian epistemology falters precisely because of the primacy given to epistemic agency. Specifically, I take a close look at Lynn Hankinson Nelson?s notion of epistemological communities in terms of epistemic agency and analyze both its merits and its shortcomings. This is an important analysis for general consideration given the trend in non-traditional epistemologies to look towards social complexes as the real seats of knowledge. But this is also important because my analysis pushes one to consider an alternative framing concept for epistemology?that of epistemic practises instead of epistemic agency.

Given the hundreds of articles and books that have been written in epistemology over the span of just the past few decades, relatively little has been written specifically on epistemic responsibility. What has been written rarely considers the nature of epistemic responsibility and its possible role in epistemic justification or knowledge. Instead, such work concerns philosophical analyses and arguments about related concepts such as epistemic virtues or duties, rather than epistemic praiseworthiness and blameworthiness.2 It is epistemic responsibility in the blameworthiness and praiseworthiness senses that is the primary concern of this paper, though the duty sense of epistemic responsibility is explored in terms of its pertinence to epistemic virtue. What is epistemic responsibility? And what, if anything, is its relationship to justification and knowledge?
