Contribution to a symposium on Keith DeRose's book, The Case for Contextualism: Knowledge, Skepticism, and Context.

There is pragmatic encroachment on some epistemic status just in case whether a proposition has that status for a subject depends not only on the subject's epistemic position with respect to the proposition, but also on features of the subject's non-epistemic, practical environment. Discussions of pragmatic encroachment usually focus on knowledge. Here we argue that, barring infallibilism, there is pragmatic encroachment on what is arguably a more fundamental epistemic status – the status a proposition has when it is warranted enough (...) to be a reason one has for believing other things.

We begin by asking what fallibilism about knowledge is, distinguishing several conceptions of fallibilism and giving reason to accept what we call strong epistemic fallibilism, the view that one can know that something is the case even if there remains an epistemic chance, for one, that it is not the case. The task of the paper, then, concerns how best to defend this sort of fallibilism from the objection that it is “mad,” that it licenses absurd claims such as “I (...) know that p but there’s a chance that not p ” and “ p but it there’s a chance that not p .” We argue that the best defense of fallibilism against this objection—a “pragmatist” defense—makes the following claims. First, while knowledge that p is compatible with an epistemic chance that not- p , it is compatible only with an insignificant such chance. Second, the insignificance of the chance that not- p is plausibly understood in terms of the irrelevance of that chance to p ’s serving as a ‘justifier’, for action as well as belief. In other words, if you know that p , then any chance for you that not p doesn’t stand in the way of p ’s being properly put to work as a basis for action and belief. (shrink)

Knowledge in an Uncertain World is an exploration of the relation between knowledge, reasons, and justification. According to the primary argument of the book, you can rely on what you know in action and belief, because what you know can be a reason you have and you can rely on the reasons you have. If knowledge doesn't allow for a chance of error, then this result is unsurprising. But if knowledge does allow for a chance of error--as seems required if (...) we know much of anything at all--this result entails the denial of a received position in epistemology. Because any chance of error, if the stakes are high enough, can make a difference to what can be relied on, two subjects with the same evidence and generally the same strength of epistemic position for a proposition can differ with respect to whether they are in a position to know. In defending these points, Fantl and McGrath investigate the ramifications for debates about epistemological externalism and contextualism, the value and importance of knowledge, Wittgensteinian hinge propositions, Bayesianism, and the nature of belief. The book is essential reading for epistemologists, philosophers who work on reasons and rationality, philosophers of language and mind, and decision theorists. (shrink)

We argue, contrary to epistemological orthodoxy, that knowledge is not purely epistemic -- that knowledge is not simply a matter of truth-related factors (evidence, reliability, etc.). We do this by arguing for a pragmatic condition on knowledge, KA: if a subject knows that p, then she is rational to act as if p. KA, together with fallibilism, entails that knowledge is not purely epistemic. We support KA by appealing tothe role of knowledge-citations in defending and criticizing actions, and by giving (...) a principled argument for KA, based on the inference rule KB: if a subject knows that A is the best thing she can do, she is rational to do A. In the second half of the paper, we consider and reject the two most promising objections to our ease for KA, one based on the Gricean notion of conversational implicature and the other based on a contextualist maneuver.

Much of the plausibility of epistemic conservatism derives from its prospects of explaining our rationality in holding memory beliefs. In the first two parts of this paper, I argue for the inadequacy of the two standard approaches to the epistemology of memory beliefs, preservationism and evidentialism. In the third, I point out the advantages of the conservative approach and consider how well conservatism survives three of the strongest objections against it. Conservatism does survive, I claim, but only if qualified in (...) certain ways. Appropriately qualified, conservatism is no longer the powerful anti-skeptical tool some have hoped for, but a doctrine closely connected with memory. (shrink)

One familiar form of argument for rejecting entities of a certain kind is that, by rejecting them, we avoid certain difficult problems associated with them. Such problem-avoidance arguments backfire if the problems cited survive the elimination of the rejected entities. In particular, we examine one way problems can survive: a question for the realist about which of a set of inconsistent statements is false may give way to an equally difficult question for the eliminativist about which of a set of (...) inconsistent statements fail to be 'factual'. Much of the first half of the paper is devoted to explaining a notion of factuality that does not imply truth but still consists in 'getting the world right'. The second half of the paper is a case study. Some 'compositional nihilists' have argued that, by rejecting composite objects (and so by denying the composition ever takes place), we avoid the notorious puzzles of coincidence, for example, the statue/lump and the ship of Theseus puzzles. Using the apparatus developed in the first half of the paper, we explore the question of whether these puzzles survive the elimination of composite objects. (shrink)

This paper argues, in response to Huw Price, that deflationism has the resources to account for the normativity of truth. The discussion centers on a principle of hyper-objective assertibility, that one is incorrect to assert that p if not-p. If this principle doesn't state a fact about truth, it neednt be explained by deflationists. If it does,, it can be explained.

The correspondence theory of truth is often thought to be supported by the intuition that if a proposition (sentence, belief) is true, then something makes it true. I argue that this appearance is illusory and is sustained only by a conflation of two distinct notions of truthmaking, existential and non-existential. Once the conflation is exposed, I maintain, deflationism is seen to be adequate for accommodating truthmaking intuitions.

McGrath argues for an original theory truth that combines elements of two well-known philosophical theories--deflationism and correspondence.

Is truth a substantial feature of truth-bearers? Correspondence theorists answer in the affirmative, deflationists in the negative. Correspondence theorists cite in their defense the dependence of truth on meaning or representational content. Deflationists in turn cite the conceptual centrality of simple equivalences such as ''Snow is white' is true iff snow is white'' and 'It is true that snow is white iff snow is white'. The apparent facts to which these theorists appeal correspond to some of our firmest and most (...) basic convictions about truth. An account of truth that fails to accommodate either sort of apparent fact is inadequate. The account presented in this essay attempts to avoid this inadequacy by 'deflating' truth for propositions but 'inflating' truth for entities that express propositions, thus drawing from the insights of both deflationists and correspondence theorists.
