According to Schellenberg, our perceptual experiences have the epistemic force they do because they are exercises of certain sorts of capacity, namely capacities to discriminate particulars—objects, property-instances and events—in a sensory mode. She calls her account the “capacity view.” In this paper, I will raise three concerns about Schellenberg’s capacity view. The first is whether we might do better to leave capacities out of our epistemology and take content properties as the fundamental epistemically relevant features of experiences. I argue we would. The second is whether Schellenberg’s appeal to factive and phenomenal evidence accommodates the intuitive verdicts about the bad case that she claims it does. I argue it does not. The third is whether Schellenberg’s account of factive evidence is adequate to capture nuances concerning the justification for singular but nondemonstrative perceptual beliefs, such as the belief that’s NN, where NN is a proper name. I argue it is not. If I am right, these points suggest a mental-state-first account of perceptual justification, rather than a capacity-first account, and one which treats the good and bad cases alike in respect of justification and complicates the relation between perceptual content and what one is justified in believing

Walking through the supermarket, I see the avocados. I know they are avocados. Similarly, if you see a pumpkin on my office desk, you can know it’s a pumpkin from its looks. The phenomenology in such cases is that of “just seeing” that such and such. This phenomenology might suggest that the knowledge gained is immediate. This paper argues, to the contrary, that in these target cases, the knowledge is mediate, depending as it does on one’s knowledge of what the relevant kind of thing looks like. To make the case requires examining the nature of knowing what Fs look like. Is such knowledge to be understood as knowledge of a fact, or rather as a kind of ability? From the conclusion that the knowledge in the target cases is not immediate, the paper concludes that perception does not afford us immediate knowledge concerning objects’ kinds.

This paper is a critical response to Eli Hirsch’s recent work in metaontology. Hirsch argues that several prominent ontological disputes about physical objects are verbal, a conclusion he takes to vindicate common sense ontology. In my response, I focus on the debate over composition (van Inwagen’s special composition question). I argue that given Hirsch’s own criterion for a dispute’s being verbal – a dispute is verbal iff charity requires each side to interpret the other sides as speaking the truth in their own languages –his case for verbalness comes up short. Hirsch ignores an important facet of charity, which I call charity to expressibility, viz. that we ought ceteris paribus to interpret linguistic communities as not speaking expressively impoverished languages. In fact, I argue that given his criterion, the debate over composition turns out nonverbal. I close by suggesting that even if the dispute over composition is nonverbal, the sides can arrive at a kind of limited conciliation through charitable interpretation of one another. Each side ought to interpret a great many of the other sides claims as “factual” even if false.

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.

I offer an account of truth that combines elements of deflationism and traditional correspondence theories. We need such an intermediary account, I argue, in order to adequately answer two kinds of questions: "Why do we find it obvious that 'p' is true iff p?" and "Why is it contingent that 'p' is true iff p?" If what it is for 'p' to be true is explained by simply saying that p, as the deflationist claims, it is hard to see how it could be contingent that 'p' is true iff p. But if it is claimed instead that what it is for a sentence to be true is for it to correspond to a fact, we still need some explanation of why 'p's correspondence with reality insure that p, and vice versa. What we need, I claim, is to recognize a structure to truth: truth for sentences, utterances, and other non-propositional entities depends on, and is analyzable in terms of, the expression of true propositions. Propositional truth can then be treated as insubstantial, as deflationary, and truth for other entities as substantial, consisting of correspondence to a fact . ;This account of truth, which I call Weak Deflationism, anchors the dissertation. In an introductory chapter, I give a partial defense of realism about propositions and properties, later defending Platonism against attacks by David Lewis. After formulating Weak Deflationism, I examine its implications for such matters as the "absurd comparison" objection, the truthmaker project in ontology, and non-factualist theories in metaethics. In a final chapter, I provide a Kripke-inspired modification of Weak Deflationism aimed to avoid liar-like paradox. Premised on a distinction between propositions that predicatively involve truth, i.e., truth-dependent propositions, and those that do not, truth-independent propositions, I argue that truth for the latter is deflationary and that truth for the former consists in being determined by the totality of truth-independent fact. Falsity is understood as truth of the negation. Liars are then counted neither true nor false, and paradox is averted.

The two main theories of perceptual reasons in contemporary epistemology can be called Phenomenalism and Factualism. According to Phenomenalism, perceptual reasons are facts about experiences conceived of as phenomenal states, i.e., states individuated by phenomenal character, by what it’s like to be in them. According to Factualism, perceptual reasons are instead facts about the external objects perceived. The main problem with Factualism is that it struggles with bad cases: cases where perceived objects are not what they appear or where there is no perceived object at all. The main problem with Phenomenalism is that it struggles with good cases: cases where everything is perfectly normal and the external object is correctly perceived, so that one’s perceptual beliefs are knowledge. In this paper we show that there is a theory of perceptual reasons that avoids the problems for Factualism and Phenomenalism. We call this view Propositionalism. We use ‘proposition’ broadly to mean the entities that are contents of beliefs and other doxastic attitudes. The key to finding a middle ground between Phenomenalism and Factualism, we claim, is to allow our reasons to be false in bad cases. Despite being false, they are about the external world, not our phenomenal states
