I take as my starting point the evident fact that people are capable of modifying their beliefs in response to reasons in the course of deliberation. This fact is sufficient to make notions such as responsibility, blameworthiness, and praiseworthiness applicable to people with regard to their beliefs. If a state is such, and one is such, that one is capable of determining it through one’s best evaluations of reasons in the course of deliberation, then even if it isn’t under one’s voluntary control, it is attributable to one as something for which one is appropriately held accountable. There is thus conceptual space for the possibility of one’s conducting oneself poorly or well with regard to it, and accordingly for the application of praise or criticism. And there is room for an evaluation of whether one has conducted oneself responsibly or irresponsibly – that is, whether one has proceeded in a way that takes proper account of the considerations which one reasonably could have been expected to take account of, or not.

This paper responds to Stephen Hetherington's discussion of my ‘Is Fallibility an Epistemological Shortcoming?’ (2004). The Infallibilist skeptic holds that in order to know something, one must be able to rule out every possible alternative to the truth of one’s belief. This requirement is false. In this paper I first clarify this requirement’s relation to our ordinary practice. I then turn to a more fundamental issue. The Infallibilist holds – along with many non-skeptical epistemologists – that Infallibility is epistemically superior to the epistemic position attained when we have (what we ordinarily call) knowledge. This is false, too, as our ordinary practices show. Ordinary epistemic appraisal does not concern our standing on a scale of evaluation which has Infallibility at its apex. For this reason, even if gradualism is correct, it does not show how Infallibilist skepticism can arise out of our ordinary practice.

In Knowledge and Its Limits, Timothy Williamson argues that knowledge is a purely mental state, that is, that it is never a complex state or condition comprising mental factors and non-mental, environmental factors. Three of his arguments are evaluated: arguments from (1) the non-analyzability of the concept of knowledge, (2) the “primeness” of knowledge, and (3) the (alleged) inability to satisfactorily specify the “internal” element involved in knowledge. None of these arguments succeeds. Moreover, consideration of the third argument points the way to a cogent argument that knowledge is not a purely mental state.

“Moorean Dogmatist” responses to external world skepticism endorse courses of reasoning that many people find objectionable. This paper seeks to locate this dissatisfaction in considerations about epistemic responsibility. I sketch a theory of immediate warrant and show how it can be combined with plausible “inferential internalist” demands arising from considerations of epistemic responsibility. The resulting view endorses immediate perceptual warrant but forbids the sort of reasoning that “Moorean Dogmatism” would allow. A surprising result is that Dogmatism’s commitment to immediate epistemic warrant isn’t enough to avoid certain standard arguments for skepticism about the external world

If p is false, it isn't evidence for anything. This view is central in one important response to a familiar sceptical argument. I consider and reject various motivations for refusing to accept this view – proposals arising from, e.g., our practice of providing rationalising explanations of people's beliefs, various locutions appearing to relativise evidence to persons, the significance of people's mental states for attributions of reasons to them, and the role of evidence in epistemic principles and requirements. I close by considering responses to the ‘New Evil Demon Argument’. What emerges is an affirmation of the principle that p doesn't provide evidence unless it is true, a response to an important version of the Evil Demon argument for scepticism, and also a deeper interpretation of our epistemic practice

Modern-day heirs of the Cartesian revolution have been fascinated by the thought that one could utilize certain hypotheses – that one is dreaming, deceived by an evil demon, or a brain in a vat – to argue at one fell swoop that one does not know, is not justified in believing, or ought not believe most if not all of what one currently believes about the world. A good part of the interest and mystique of these discussions arises from the contention that the seeds of such arguments lie in our ordinary epistemic practices, so that external world skepticism can arise “from within”. But is this contention correct? I doubt it. Taking skepticism seriously requires that we address this question head on. To do so, I will approach skeptical arguments from a certain vantage point. I will try to stand, as far as possible, with both feet squarely in ordinary life. I will start out with all of our ordinary commitments about what is the case, about what we know or have reason to believe, about when someone knows, is justified, or has good reason to believe something, and about how one should proceed in deciding what to believe. My question, then, will be this. From within that vantage point can I somehow be moved in a reasonable way to accept the conclusion that I know far less about the world around me than I thought, or that epistemically speaking, I really ought not believe much of what I have believed about the world around me? In order for such movement to take place, I will have to find reason from within my ordinary standpoint to discount or reject much of what I ordinarily accept. And of course, that reason will have to come from some..

We commonly speak of people as being ‘‘justified’’ or ‘‘unjustified’’ in believing as they do. These terms describe a person’s epistemic condition. To be justified in believing as one does is to have a positive epistemic status in virtue of holding one’s belief in a way which fully satisfies the relevant epistemic requirements or norms. This requires something more (or other) than simply believing a proposition whose truth is well-supported by evidence, even by evidence which one possesses oneself, since one could entirely miss the relevance of this evidence and hold the belief as a result of wishful thinking or for some other bad reason. My topic in this paper is the notion of being justified which precludes beliefs flawed in this way. I will take the notion of something’s telling in favor of the truth of a proposition—that is, the notion of evidential support—for granted.

J. L. Austin’s attitude towards traditional epistemological problems was largely negative. They arise and are maintained, he charged, by “sleight of hand,” “wile,” “concealed motives,” “seductive fallacies,” fixation on a handful of “jejune examples” and a host of small errors, misinterpretations, and mistakes about matters of fact (1962: 3- 6, 1979: 87). As these charges indicate, he did not offer a general critical theory of traditional epistemological theorizing or of the intellectual motivations that lead to it. Instead, he subjected individual arguments to piecemeal criticism, patiently showing how things go awry in conception, motivation, argumentation, and plain fact. The work was incremental, but the goal was radical: to reduce large edifices to rubble. As he put it regarding certain sense datum theories, “the right policy is to go back to a much earlier stage, and to dismantle the whole doctrine before it gets off the ground” (1962: 142). It is often said that Austin’s criticisms were linguistic, but this is only partly right. While he occasionally charges traditional epistemologists with misusing crucial words and relying on unregulated and inadequately motivated technical terms, he also charges them with factual errors and with distorting or misunderstanding the procedures involved in epistemically evaluating people’s claims and beliefs. For this reason, it is best to see Austin as criticizing traditional epistemological puzzles and projects from the point of view of our ordinary lives (including our best scientific theories and practices). He starts with a commitment to our ordinary ways of using words, our ordinary convictions about..
