Murray G. Murphey’s masterful treatment of C. I. Lewis’s philosophy leaves two things amply clear: first, that Lewis struggled with skeptical arguments from Hume throughout his career; and second, that Lewis never adequately resolved the problems raised by those arguments. In this paper I will consider Lewis’s approach to Hume’s skepticism in Mind and the World Order (MWO) and in An Analysis of Knowledge and Valuation (AKV), and I will argue that Lewis’s reply to Hume in these works did not change as dramatically as Murphey claims. Nevertheless, I agree with Murphey that there are two quite different lines of reply discernable in Lewis, and that neither adequately answers Hume. In the final part of the paper I argue that Lewis’s pragmatism gives us resources for an adequate reply to Hume’s skeptical arguments, although it is not the reply that Lewis himself gives.

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.

For over thirty years, Robert Audi has produced important work in ethics, epistemology, and the theory of action. This volume features thirteen new critical essays on Audi by a distinguished group of authors: Fred Adams, William Alston, Laurence BonJour, Roger Crisp, Elizabeth Fricker, Bernard Gert, Thomas Hurka, Hugh McCann, Al Mele, Walter Sinnott-Armstrong, Raimo Tuomela, Candace Vogler, and Timothy Williamson. Audi's introductory essay provides a thematic overview interconnecting his views in ethics, epistemology, and philosophy of action. The volume concludes with his comprehensive response essay that yields an illuminating dialog with all his critics and often extends his previous work.

Section 1 articulates a genus-species claim: that knowledge is a kind of success from ability. Equivalently: In cases of knowledge, S’s success in believing the truth is attributable to S’s ability. That idea is then applied to questions about the nature and value of knowledge. Section 2 asks what it would take to turn the genus-species claim into a proper theory of knowledge; that is, into informative, necessary and sufficient conditions. That question is raised in the context of an important line of objection against even the genus-species claim; namely, that there is no way to understand the attribution relation so that it does all the work that it is supposed to do. Section 3 reviews several extant proposals for understanding the attribution relation, and argues that none of them are adequate for answering the objection. Section 4 proposes a different way of understanding the relation, and shows how the resulting view does resolve the objection. Section 5 completes the new account by proposing a way to understand intellectual abilities. Section 6 briefly addresses Barn Façade cases and lottery propositions. Section 7 briefly addresses a question about the scope of knowledge; in particular, it shows how the new view allows a neo-Moorean response to skepticism

This paper explores a familiar skeptical problematic and considers some strategies for responding to it. Section 1 reconstructs and disambiguates the skeptical problematic, distinguishing between some importantly different lines of skeptical reasoning. Section 2 distinguishes two kinds of anti-skeptical strategy. “Cooperative strategies” accept the conditions on knowledge that are laid down by a target skeptical argument, and argue that those conditions can be satisfied in a relevant domain. “Critical strategies” respond to a skeptical argument by rejecting some condition on knowledge that the argument supposes. It is argued that critical strategies readily present themselves against the skeptical problematic once it is disambiguated as in Section 1. Section 3 looks at an interesting anti-skeptical strategy from Ram Neta and Duncan Pritchard on behalf of John McDowell. Here I argue that, initial appearances to the contrary, no plausible cooperative strategy is available to the internalist
