Your evidence constrains your rational degrees of confidence both locally and globally. On the one hand, particular bits of evidence can boost or diminish your rational degree of confidence in various hypotheses, relative to your background information. On the other hand, epistemic rationality requires that, for any hypothesis h, your confidence in h is proportional to the support that h receives from your total evidence. Why is it that your evidence has these two epistemic powers? I argue that various proposed accounts of what it is for something to be an element of your evidence set cannot answer this question. I then propose an alternative account of what it is for something to be an element of your evidence set. 1 Introduction 2 The elements of one's evidence set are propositions 3 Which kinds of propositions are in one's evidence set? 3.1 Doxastic accounts of evidence 3.2 Non-doxastic accounts of evidence 4 Elaborating and defending the LIE CiteULike    Connotea    Del.icio.us    What's this?

Sometimes, there are reasons for which we believe, intend, resent, decide, and so on: these reasons are the “bases” of the latter, and the explanatory relation between these bases and the latter is what I will call “the basing relation.” What kind of explanatory relation is this? Dispositionalists claim that the basing relation consists in the agent’s manifesting a disposition to respond to those bases by having the belief, intention, resentment, and so on, in question. Representationalists claim that the basing relation consists in the agent’s representing the bases as justifying the belief, intention, resentment, and so on, in question. This article shows that an adequate account of the basing relation requires a particular refinement and combination of these two views. On the hybrid account defended here, the basing relation involves a disposition exercise that is individuated by the agent’s object-involving de se representation of that very exercise as justifying.

Epistemology is one of the oldest, yet still one of the most active, areas of philosophical research today. There currently exists many annotated tomes of primary sources, and a handful of single-authored introductions to the field, but there is no book that captures epistemology’s dynamic growth and lively debates for a student audience. In this volume, eight leading philosophers debate four topics central to recent research in epistemology: The A Priori: C. S. I. Jenkins and Michael Devitt The A Posteriori: Richard Fumerton and Nicholas Silins The Regress of Justification: Declan Smithies and Peter Klein Skepticism: Anthony Brueckner and Ernest Sosa Ram Neta’s introduction to the volume, descriptions of each chapter, annotated bibliographies for each controversy, and supplemental guide to further controversies in epistemology help provide clearer and richer views of active controversies for all readers.

In his recent Knowledge and its Limits, Timothy Williamson argues that no non-trivial mental state is such that being in that state suffices for one to be in a position to know that one is in it. In short, there are no “luminous” mental states. His argument depends on a “safety” requirement on knowledge, that one’s confident belief could not easily have been wrong if it is to count as knowledge. We argue that the safety requirement is ambiguous; on one interpretation it is obviously true but useless to his argument, and on the other interpretation it is false

Many philosophers accept a “privileged access” thesis concerning our own present mental states and mental events. According to these philosophers, if I am in mental state (or undergoing mental event) M, then – at least in many cases – I have privileged access to the fact that I am in (or undergoing) M. For instance, if I now believe that my cat is sitting on my lap, then (in normal circumstances) I have privileged access to the fact that I now believe that my cat is sitting on my lap. Similarly, if I now imagine a parade coming down Main Street, then (again, in normal circumstances) I have privileged access to the fact that I am now imagining a parade coming down Main Street. And again, if it now visually appears to me as if there is a cloud in the sky, then (again, in normal circumstances) I have privileged access to the fact that it now visually appears to me as if there is a cloud in the sky. In each of these aforementioned cases, if circumstances are normal, then, these philosophers say, I have a distinctive kind of privileged epistemic access to facts about my own mental states or events. Of course, I don’t have privileged epistemic access to all facts about my own mental states or events. For instance, I don’t have privileged epistemic access to facts about which unconscious mental states or events I have. But I do have privileged epistemic access to many facts about my own mental states or events, and in particular to the various facts listed above.

According to "skepticism about the external world", one cannot know whether there are any things that have these two characteristics: they exist, or occur, at, or come from, some place, and they might have existed even had no one been conscious of them. In attempting to show that one cannot know whether or not there are any such things, the skeptic appeals to the alleged fact that one cannot rule out various possibilities, e.g., the possibility that one is dreaming. But, if one cannot rule out these possibilities, then how can one even have any grounds for believing that there are such things? I show how certain attempts to explain how one can have such grounds cannot succeed, and I offer an alternative that does succeed. This alternative depends upon a certain analysis of the notion of sensory experience. After providing that analysis, and showing how, by appeal to it, we can explain not only how it is possible to have grounds for believing that there are external things, but how it is possible to know that there are, I explain why it is that philosophers have failed to appreciate the possibility of providing such an explanation. In offering this explanation, I also explain why it is that skepticism about the external world, as well as various other philosophical doctrines, is subject to what I call "instability"

Rieber 1998 proposes an account of "S knows that p" that generates a contextualist solution to Closure. In this paper, I’ll argue that Rieber’s account of "S knows that p" is subject to fatal objections, but we can modify it to achieve an adequate account of "S knows that p" that generates a unified contextualist solution to all four puzzles. This is a feat that should matter to those philosophers who have proposed contextualist solutions to Closure: all of them have motivated their contextualism by appeal to the fact that they can explain the plausibility of each of the statements in Closure taken individually, and they can do this without having to deny that each of those statements is true, at least in the context in which it is plausible. But notice that this consideration would equally well motivate a contextualist approach to the other puzzles. Nonetheless, no contextualist has yet suggested how a contextualist solution to the other puzzles might go

Stephen Schiffer has argued that contextualist solutions to skepticism rest on an implausible "error theory" concerning our own semantic intentions. Similar arguments have recently been offered also by Thomas Hofweber and Patrick Rysiew. I attempt to show how contextualists can rebut these arguments. The kind of self-knowledge that contextualists are committed to denying us is not a kind of self-knowledge that we need, nor is it a kind of self-knowledge that we can plausibly be thought to possess
