Abstract:   Since the most promising path to a solution to the problem of skepticism regarding perceptual knowledge seems to rest on a sharp distinction between perceiving and inferring, I begin by clarifying and defending that distinction. Next, I discuss the chief obstacle to success by this path, the difficulty in making the required distinction between merely logical possibilities that one is mistaken and the real (Austin) or relevant (Dretske) possibilities which would exclude knowledge. I argue that this distinction cannot be drawn in the ways Austin and Dretske suggest without begging the questions at issue. Finally, I sketch and defend a more radical way of identifying relevant possibilities that is inspired by Austin's controversial suggestion of a parallel between saying I know and saying I promise: a claim of knowledge of some particular matter is relative to a context in which questions about the matter have been raised

Abstract: The question I am interested in is this. What exactly is the role of conscious experience in the acquisition of knowledge on the basis of perception? The problem here, as I see it, is to solve simultaneously for the nature of this experience, and its role in acquiring and sustaining the relevant beliefs, in such a away as to vindicate what I regard as an undeniable datum, that perception is a basic source of knowledge about the mind- independent world, in a sense of ‘basic’ which is also to be elucidated. I shall sketch the way in which I think that this should be done. In section I, I argue that perceptual experiences must provide reasons for empirical beliefs. In section II, I explain how they do so. My thesis is that a correct account of the sense in which perceptual experiences are experiences of mind-independent things is itself an account of the way in which they provide peculiarly basic reasons for beliefs about the world around the perceiver

Abstract: What is the role of conscious perceptual experience in making thought about the mind- independent empirical world possible? What is the role of such experience in the acquisition of empirical knowledge, about the way things are in that world? What is the relation between these two roles? My central argument is intended to establish that a proper account of the way in which perceptual experience is essential to our grasp of determinate thoughts about particular things in the world around us will at the same time yield a full explanation of the fundamental role which such experience plays in the acquisition of empirical knowledge, by providing us with reasons, which we recognize as such, to endorse the most basic thoughts about mind-independent things in belief

Abstract: We have justified beliefs about the “external” world, and some of these are formed directly on the basis of perception. I may justifiably believe that a certain dog is in certain manger, and I may have this belief because I can see that the dog is in the manger. So far, so good

Abstract: It is often thought that epistemic relations between experience and belief make it possible for our beliefs to be about or "directed towards" the empirical world. I focus on an influential attempt by John McDowell to defend a view along these lines. According to McDowell, unless experiences are the sorts of things that can be our reasons for holding beliefs, our beliefs would not be "answerable" to the facts they purportedly represent, and so would lack all empirical content. I argue that there is no intelligible conception of what it is for beliefs to be answerable to the facts that supports McDowell's claim that our empirical beliefs must be justified by experience

Abstract: According to Conceptualists like John McDowell and Bill Brewer, the representational content of perceptual experiences is wholly conceptual. One of the main!and only!arguments they advance for this claim has to do with the epistemological role of perceptual experiences. I focus on Bill Brewer’s "1999# version of the argument. I show why Brewer fails to satisfactorily motivate the premises of his argument, and suggest that opponents of Conceptualism could accept these premises without thereby endorsing the conclusion. Finally, I consider whether the conclusion really supports Conceptualism

Abstract: Any adequate account of perceptual experience has to provide answers to the following questions: What kind, and form of, content do experiences have? What kind of mental states are they? Many, if not most philosophers of perception today agree that experiences have representational contents of the form x is F, where x ranges over material objects and F over sensible properties. I argue that such a ‘naive semantics’ for experiences has to give the wrong answer to the second question. Because of their justificatory role for, and inferential integration into, a subject’s belief system, experiences themselves have to be construed as a kind of belief. I also sketch a semantics that allows experiences to be beliefs. Pdf

Abstract: A major theme in rap lyrics is that the only way to survive is to use your head, be aware, know what’s going on around you. That simple idea packs a lot of background. The most obvious ideas about knowledge turn out if you look at them close up to be pretty questionable. For example: How do we get knowledge about the world? A natural and ancient answer to this question is that much if not all of our knowledge comes from our senses. So for example the nose gives us knowledge of what things smell like, and if all goes well, also indicates whether the thing we’re smelling is healthy, tasty, or noxious. Likewise, the eyes tell us the color and shape of things, and thereby give us information about whether those things are useful, dangerous, and so on. Like everybody else, rappers know all this. Or do they? Maybe some rappers know that this isn’t really so

Abstract: Can anything other than a belief confer epistemic justification on a belief? In particular, can nondoxastic experiential states do so? According to the standard taxonomy, _doxasticism _is the view that only beliefs can justify beliefs; _nondoxasticism _is simply the denial of this. The distinction between doxastic and nondoxastic theories is central to epistemology, but much of the debate surrounding it has been marred by an unnoticed ambiguity concerning the key concept of justification. Sorting out the ambiguity reveals an important division between externalist and internalist varieties of nondoxasticism and points the way toward a new argument for nondoxasticism of the externalist sort

Abstract: In at least some cases of justified perceptual belief, our perceptual experience itself, as opposed to beliefs about it, evidences and thereby justifies our belief. While the phenomenon is common, it is also mysterious. There are good reasons to think that perceptions cannot justify beliefs directly, and there is a significant challenge in explaining how they do. After explaining just how direct perceptual justification is mysterious, I considerMichael Huemer’s (Skepticism and the Veil of Perception, 2001) and Bill Brewer’s (Perception and Reason, 1999) recent, but radically different, attempts to eliminate it. I argue that both are unsuccessful, though a consideration of their mistakes deepens our appreciation of the mystery

Abstract: Imagine yourself sitting on your front porch, sipping your morning coffee and admiring the scene before you. You see trees, houses, people, automobiles; you see a cat running across the road, and a bee buzzing among the flowers. You see that the flowers are yellow, and blowing in the wind. You see that the people are moving about, many of them on bicycles. You see that the houses are painted different colors, mostly earth tones, and most are one-story but a few are two-story. It is a beautiful morning. Thus the world interfaces with your mind through your senses. There is a strong intuition that we are not disconnected from the world. We and the other things we see around us are part of a continuous whole, and we have direct access to them through vision, touch, etc. However, the philosophical tradition tries to drive a wedge between us and the world by insisting that the information we get from perception is the result of inference from indirect evidence that is about how things look and feel to us. The philosophical problem of perception is then to explain what justifies these inferences. We will focus on visual perception. Figure one presents a crude diagram of the cognitive system of an agent capable of forming beliefs on the basis of visual perception. Cognition begins with the stimulation of the rods and cones on the retina. From that physical input, some kind of visual processing produces an introspectible visual image. In response to the production of the visual image, the cognizer forms beliefs about his or her surroundings. Some beliefs — the perceptual beliefs — are formed as direct responses to the visual input, and other beliefs are inferred from the perceptual beliefs. The perceptual beliefs are, at the very least, caused or causally influenced by having the image. This is signified by the dashed arrow marked with a large question mark. We will refer to this as the mystery link. Figure one makes it apparent that in order to fully understand how knowledge is based on perception, we need three different theories..
