Chapter 4 of Being Known outlines an integrated metaphysics and epistemology for the metaphysical—absolute—notions of necessity and possibility. The leading idea is to view the modal status of a proposition as the deliverance of a set of fundamental Principles of Possibility, and our ability to recognise modal status as issuing from an implicit knowledge of these principles. Peacocke aims at a middle way between the extremes of Lewis-style realism about modality and the various—conventionalist, expressivist, Wittgensteinian—forms of non-cognitivism that were prominent (...) in the last century. An attraction of his account is its unified treatment both of a priori logical—more generally, conceptual—necessity and possibility and of a posteriori necessities of essence, identity, origin and constitution, etc. The treatment is ambitious and rich in invention and original detail, but Peacocke professes himself more wedded to the general approach than to the particular development. I shall correspondingly confine my remarks, more or less, to the general approach. (shrink)

Knowledge and its Limits presents a systematic new conception of knowledge as a kind of mental stage sensitive to the knower's environment. It makes a major contribution to the debate between externalist and internalist philosophies of mind, and breaks radically with the epistemological tradition of analyzing knowledge in terms of true belief. The theory casts new light on such philosophical problems as scepticism, evidence, probability and assertion, realism and anti-realism, and the limits of what can be known. The arguments are (...) illustrated by rigorous models based on epistemic logic and probability theory. The result is a new way of doing epistemology and a notable contribution to the philosophy of mind. (shrink)

I argue against the orthodox view of the relationship between propositional and doxastic justification. The view under criticism is: if p is propositionally justified for S in virtue of S's having reason R, and S believes p on the basis of R, then S's belief that p is doxastically justified. I then propose and evaluate alternative accounts of the relationship between propositional and doxastic justification, and conclude that we should explain propositional justification in terms of doxastic justification. If correct, this (...) proposal would constitute a significant advance in our understanding of the sources of epistemic justification. (shrink)

The Neo-Moorean Deduction (I have a hand, so I am not a brain-in-a-vat) and the Zebra Deduction (the creature is a zebra, so isn’t a cleverly disguised mule) are notorious. Crispin Wright, Martin Davies, Fred Dretske, and Brian McLaughlin, among others, argue that these deductions are instances of transmission failure. That is, they argue that these deductions cannot transmit justification to their conclusions. I contend, however, that the notoriety of these deductions is undeserved. My strategy is to clarify, attack, defend, (...) and apply. I clarify what transmission and transmission failure really are, thereby exposing two questionable but quotidian assumptions. I attack existing views of transmission failure, especially those of Crispin Wright. I defend a permissive view of transmission failure, one which holds that deductions of a certain kind fail to transmit only because of premise circularity. Finally, I apply this account to the Neo-Moorean and Zebra Deductions and show that, given my permissive view, these deductions transmit in an intuitively acceptable way—at least if either a certain type of circularity is benign or a certain view of perceptual justification is false.

Entitlement is conceived as a kind of positive epistemic status, attaching to certain propositions, that involves no cognitive or intellectual accomplishment on the part of the beneficiary — a status that is in place by default. In this paper I will argue that the notion of entitlement — or something very like it — falls out of an idea that may at first blush seem rather disparate: that the evidential support relation can be understood as a kind of variably strict (...) conditional (in the sense of Lewis 1973). Lewis provided a general recipe for deriving what he termed inner modalities from any variably strict conditional governed by a logic meeting certain constraints. On my proposal, entitlement need be nothing more exotic than the inner necessity associated with evidential support. Understanding entitlement in this way helps to answer some common concerns — in particular, the concern that entitlement could only be a pragmatic, and not genuinely epistemic, status. (shrink)

I set out the standard view about alleged examples of failure of transmission of warrant, respond to two cases for the view, and argue that the view is false. The first argument for the view neglects the distinction between believing a proposition on the basis of a justification and merely having a justification to believe a proposition. The second argument for the view neglects the position that one's justification for believing a conclusion can be one's premise for the conclusion, rather (...) than simply one's justification for the premise. Finally, the view is false since it is inconsistent with the closure of knowledge as closure is properly understood. (shrink)

Something about this argument sounds funny. As we’ll see, though, it takes some care to identify exactly what Moore has done wrong. Iwill assume that Moore knows premise (2) to be true. One could inquire into how he knows it, and whether that knowledge can be defeated; but Iwon’t. I’ll focus instead on what epistemic relations Moore has to premise (1) and to his conclusion (3). It may matter which epistemic relations we choose to consider. Some philosophers will diagnose Moore’s (...) argument using Contextualist machinery. They’ll say. (shrink)

In this paper I discuss two fundamental challenges concerning Crispin Wright's notion of entitlement of cognitive project: firstly, whether entitlement is an epistemic kind of warrant since, seemingly, it is not underwritten by epistemic reasons, and, secondly, whether, in the absence of such reasons, the kind of rationality associated with entitlement is epistemic in nature. The paper investigates three possible lines of response to these challenges. According to the first line of response, entitlement of cognitive project is underwritten by epistemic (...) reasons – and thus supports epistemic rationality – because, when P is an entitlement, trust in P is a dominant strategy with respect to promotion of epistemic value. The second line of response replaces dominance with maximization of expected utility. I argue that both of these proposals are flawed and develop an alternative line of response. (shrink)

David Lewis (1941-2001) was Class of 1943 University Professor of Philosophy at Princeton University. His contributions spanned philosophical logic, philosophy of language, philosophy of mind, philosophy of science, metaphysics, and epistemology. In On the Plurality of Worlds, he defended his challenging metaphysical position, "modal realism." He was also the author of the books Convention, Counterfactuals, Parts of Classes, and several volumes of collected papers.

Rich with historical and cultural value, these works are published unaltered from the original University of Minnesota Press editions.

This paper takes the form of a critical discussion of Crispin Wright’s notion of entitlement of cognitive project. I examine various strategies for defending the claim that entitlement can make acceptance of a proposition epistemically rational, including one which appeals to epistemic consequentialism. Ultimately, I argue, none of these strategies is successful, but the attempt to isolate points of disagreement with Wright issues in some positive proposals as to how an epistemic consequentialist should characterize epistemic rationality.

Evidentialism is a view about the conditions under which a person is epistemically justified in having a particular doxastic attitude toward a proposition. Evidentialism holds that the justified attitudes are determined entirely by the person's evidence. This is the traditional view of justification. It is now widely opposed. The essays included in this volume develop and defend the tradition.Evidentialism has many assets. In addition to providing an intuitively plausible account of epistemic justification, it helps to resolve the problem of the (...) criterion, helps to disentangle epistemic and ethical evaluations, and illuminates the relationship between epistemic evaluations of beliefs and the evaluation of the methods used to form beliefs. These issues are all addressed in the essays presented here. External world skepticism poses the classic problem for an epistemological theory. The final essay in this volume argues that evidentialism is uniquely well qualified to make sense of skepticism and to respond to its challenge.Evidentialism is a version of epistemic internalism. Recent epistemology has included many attacks on internalism and has seen the development of numerous externalist theories. The essays included here respond to those attacks and raise objections to externalist theories, especially the principal rival, reliabilism. Internalism generally has been criticized for having unacceptable deontological implications, for failing to connect epistemic justification to truth, and for failing to provide an adequate account of what makes basic beliefs justified. Each of these charges is answered in these essays. The collection includes two previously unpublished essays and new afterwords to five of the reprinted essays; it will be the definitive resource on evidentialism for all epistemologists. (shrink)

The dominant response to this problem of the criterion focuses on the alleged requirement that we need to know a belief source is reliable in order for us to acquire knowledge by that source. Let us call this requirement, “The KR principle”.

The paper explicates a new way to model the context-sensitivity of 'knows', namely a way that suggests a close connection between the content of 'knows' in a context C and what is pragmatically presupposed in C. After explicating my new approach in the first half of the paper and arguing that it is explanatorily superior to standard accounts of epistemic contextualism, the paper points, in its second half, to some interesting new features of the emerging account, such as its compatibility (...) with the intuitions of Moorean dogmatists. Finally, the paper shows that the account defended is not subject to the most prominent and familiar philosophical objections to epistemic contextualism discussed in the recent literature. (shrink)

Knowledge and Presuppositions develops a novel account of epistemic contextualism based on the idea that pragmatic presuppositions play a central role in the semantics of knowledge attributions. According to Blome-Tillmann, knowledge attributions are sensitive to what is pragmatically presupposed at the context of ascription. The resulting theory--Presuppositional Epistemic Contextualism (PEC)--is simple and straightforward, yet powerful enough to have far-reaching and important consequences for a variety of hotly debated issues in epistemology and philosophy of language. -/- In this book, Blome-Tillmann first (...) develops Presuppositional Epistemic Contextualism and then explores its ability to resolve various sceptical paradoxes and puzzles. Blome-Tillmann also defends PEC against familiar and widely discussed philosophical and linguistic objections to contextualism. In the final chapters of the book PEC is employed to illuminate a variety of concerns central to contemporary discussions of epistemological issues, such as Gettier cases, Moorean reasoning, the nature of evidence, and other current problems and puzzles.

This paper examines the relevance of Wittgenstein’s On Certainty to the contemporary debate regarding the problem of radical scepticism. In particular, it considers two accounts in the recent literature which have seen in Wittgenstein’s remarks on “hinge propositions” in On Certainty the basis for a primarily epistemological anti-sceptical thesis—viz., the inferential contextualism offered by Michael Williams and the ‘unearned warrant’ thesis defended by Crispin Wright. Both positions are shown to be problematic, both as interpretations of Wittgenstein and as anti-sceptical theses. (...) Indeed, it is argued that on a reading of On Certainty which has Wittgenstein advancing a primarily epistemological thesis, there is in fact strong evidence to suggest that Wittgenstein thought that no epistemic response to the sceptic was available—at best, it seems, only a pragmatic antisceptical thesis is on offer. Such a conclusion is not without import to the present debate regarding radical scepticism, however, since it poses a general challenge for how the sceptical argument is conceived in the contemporary literature.

"Dogmatism" is a term renovated by James Pryor [2000] to stand for a certain kind of neo-Moorean response to Scepticism and an associated conception of the architecture of basic perceptual warrant. Pryor runs the response only for (some kinds of) perceptual knowledge but here I will be concerned with its general structure and potential as a possible global anti-sceptical strategy. Something like it is arguably also present in recent writings of Burge 1 and Peacocke.2 If the global strategy could succeed, (...) (...) it would pre-empt any role in the diagnosis and treatment of sceptical paradoxes for the kind of notion of entitlement (rational, non-evidential warrant) I have proposed elsewhere [Wright 2004]. But my overarching contention will be that Dogmatism is, generally and locally, too problematic a stance to be helpful in that project. (shrink)
