Illusionism is the thesis that phenomenal consciousness does not exist, but merely seems to exist. Many opponents to the thesis take it to be obviously false. They think that they can reject illusionism, even if they conceded that it is coherent and supported by strong arguments. David Chalmers has articulated this reaction to illusionism in terms of a “Moorean” argument against illusionism. This argument contends that illusionism is false, because it is obviously true that we have phenomenal experiences. I argue (...) that this argument fails by showing that its defenders cannot maintain that its crucial premise has the kind of support needed for the argument to work, without begging the question against illusionism.

The term ‘coherence’ (and its antonym ‘incoherence’) is used in a bewildering variety of ways in epistemology (and in philosophy more broadly). This entry attempts to bring some discipline to uses of the term by offering a taxonomy of notions of coherence (and incoherence), and then surveying which of the resulting notions is (or should be) at work in the various different contexts in which it is deployed.

A Moorean fact, in the words of the late David Lewis, is ‘one of those things that we know better than we know the premises of any philosophical argument to the contrary’. Lewis opens his seminal paper ‘Elusive Knowledge’ with the following declaration.

In this age of post-Moorean modesty, many of us are inclined to doubt that philosophy is in possession of arguments that might genuinely serve to undermine what we ordinarily believe. It may perhaps be conceded that the arguments of the skeptic appear to be utterly compelling; but the Mooreans among us will hold that the very plausibility of our ordinary beliefs is reason enough for supposing that there must be something wrong in the skeptic’s arguments, even if we are unable (...) to say what it is. In so far then, as the pretensions of philosophy to provide a world view rest upon its.. (shrink)

Reflection on the history of skepticism shows that philosophers have often conjoined as a single doctrine various theses that are best kept apart. Some of these theses are incredible – literally almost impossible to accept – whereas others seem quite plausible, and even verging on the platitudinous. Mixing them together, one arrives at a view – skepticism – that is as a whole indefensible. My aim is to pull these different elements apart, and to focus on one particular strand of (...) skepticism that deserves sustained and respectful attention. The strand I have in mind I will refer to as epistemic defeatism. Roughly, in its most global form, it is the view that, in the final analysis, we have no good evidence for the truth of any proposition. Working through various historical texts, I attempt to untangle epistemic defeatism from neighboring views, and in particular to establish its independence from questions about knowledge. Having thus established the view's autonomy, I turn to the options for self-consciously accepting defeat. One may despair or one may have faith. But I will ultimately propose that the most attractive option – the option that preserves the most of our epistemic integrity – is to have hope. (shrink)

My subject is the kind of Epistemic Conservatism (EC) that says that an agent is in some measure justified in maintaining a belief simply in virtue of the fact that the agent has that belief. Quine’s alternative to positivist foundationalism, Chisholmian particularism, Rawls’s reflective equilibrium, and Bayesianism all seem to rely on EC. I argue that, in order to evaluate EC, we must consider an agent holding a bare belief, that is, a belief stripped of all personal memory and epistemic (...) context. Taking a stylistic cue from Peter Strawson, I argue that, though it does not seem to be self-contradictory to suppose that someone has a bare belief, and so it is not absolutely inconceivable that bare beliefs exist, it is, for us as we are, practically inconceivable that bare beliefs exist. It does not seem practically feasible, then, to evaluate EC on its own terms. (shrink)

Un fait Mooréen, selon l'expression de David Lewis, est « l'une des choses que nous savons mieux que toute prémisse d'une argumentation philosophique visant à é tablir le contraire. » Le sujet des faits Mooréens soulève des questions profondes, à la fois de méthode philosophique et d'épistémologie de premier ordre. Comment devrions-nous répondre aux arguments qui remettent en question des croyances dont nous sommes extrêmement confiants ? Dans quelle mesure ces arguments – ou plutôt ceux qui les avancent – peuvent-ils (...) espérer avoir une emprise ou une traction rationnelle sur nous ? Dans quelle mesure, si même c'est le cas, notre point de départ limite-t-il les types de révisions de nos croyances que la philosophie pourrait légitimement inspirer ? Quand sommes-nous justifiés (si jamais nous le sommes) à refuser de se laisser influencer par un argument qui, pour autant qu'on puisse en juger, est sans faille, et quand un tel refus relève-t-il simplement du dogmatisme ? Ce sont là de vastes questions, auxquelles je ne tenterai pas ici de répondre complétement. Mon ambition, plus modeste, est de tenter de progresser sur ces questions, et d'autres questions connexes, en examinant la notion de fait Mooré que je trouve chez Lewis et chez d'autres. (shrink)

I argue that practical knowledge can be understood as constituted by a kind of imagining. In particular, it is the knowledge of what I am doing when that knowledge is represented via extramental imagination. Two results follow. First, on this account, we can do justice both to the cognitive character and the practical character of practical knowledge. And second, we can identify a condition under which imagination becomes factive, and thus a source of ob-jective evidence. I develop this view by (...) extracting an account of self-knowledge via extramental imagination from the writings of Ibn ‘Arabi (1165-1240). (shrink)

One common attitude toward abstract objects is a kind of platonism: a view on which those objects are mind-independent and causally inert. But there's an epistemological problem here: given any naturalistically respectable understanding of how our minds work, we can't be in any sort of contact with mind-independent, causally inert objects. So platonists, in order to avoid skepticism, tend to endorse epistemological theories on which knowledge is easy, in the sense that it requires no such contact—appeals to Boghossian’s notion of (...) epistemic analyticity are particularly common here, as are appeals to some broadly pragmatic account of the good standing of basic beliefs. I argue, though, that these appeals are hopeless: an argument adapted from the Benacerraf–Field challenge shows that, even if some such theory can deliver the verdict that our beliefs about abstract objects have some prima facie good standing, this good standing will inevitably be defeated.

Epistemic conservatism says that an agent is in some measure justified in maintaining a belief simply in virtue of the fact that the agent has that belief. In his new book On Evidence in Philosophy, William Lycan argues that there is no special objection to EC that does not also impugn the other epistemic virtues. In a forthcoming Synthese piece, Daniel Coren argues that, for us as we are, EC cannot be evaluated. Coren does not discuss Lycan, and vice versa. (...) Here I connect these two discussions of EC in order to shed light on the broader nature of epistemic virtues. Does Coren’s argument extrapolate to the other virtues? I argue that both answers to that question yield interesting results. If his argument does not extrapolate to the other virtues, that would show there is something special about EC that Lycan failed to notice. If, instead, Coren’s argument does extrapolate to the other virtues, then we learn something significant and novel about virtues such as simplicity, namely, simplicity cannot be evaluated. I discuss those results. (shrink)

The paper starts by describing and clarifying what Williamson calls the consequence fallacy. I show two ways in which one might commit the fallacy. The first, which is rather trivial, involves overlooking background information; the second way, which is the more philosophically interesting, involves overlooking prior probabilities. In the following section, I describe a powerful form of sceptical argument, which is the main topic of the paper, elaborating on previous work by Huemer. The argument attempts to show the impossibility of (...) defeasible justification, justification based on evidence which does not entail the (allegedly) justified proposition or belief. I then discuss the relation between the consequence fallacy, or some similar enough reasoning, and that form of argument. I argue that one can resist that form of sceptical argument if one gives up the idea that a belief cannot be justified unless it is supported by the totality of the evidence available to the subject—a principle entailed by many prominent epistemological views, most clearly by epistemological evidentialism. The justification, in the relevant cases, should instead derive solely from the prior probability of the proposition. A justification of this sort, that does not rely on evidence, would amount to a form of entitlement, in (something like) Crispin Wright’s sense. I conclude with some discussion of how to understand prior probabilities, and how to develop the notion of entitlement in an externalist epistemological framework. (shrink)

According to an influential conception of reasons for action, the presence of a desire or some other conative state in the agent is a necessary condition for the agent’s havinga reason for action. This is sometimes known as internalism . In this paper I present a case for the considerably stronger thesis, which I call hyper-internalism , that the presence of a desire is a sufficient condition for the agent’s having a ( prima facie )reason for action.
