What is the relation between a perceptual experience of an object X as being red, and one's belief, if any, as to the nature of that experience? A traditional Cartesian view would be that, if indeed object X does seem to be red to oneself, then one's resulting introspective belief about it could only be a _conforming _belief, i.e., a belief that X perceptually seems to be _red _to oneself--rather than, for instance, a belief that X perceptually seems to be green to oneself instead. On such a Cartesian view, our introspective certainly about our own thoughts extends also to our perceptual experiences as to how things seem to be to us, so that our resulting introspective beliefs about our phenomenal states also count as knowledge of them.

An attempt is made to pinpoint the way in which perception is related to belief. Although, for familiar reasons, it is not true to say that we necessarily believe in the existence of the objects we perceive, nor that they actually have their ostensible characteristics, it is argued that the relation between perception and belief is more than merely contingent There are two main issues to address. The first is that `collateral' beliefs may impede perceptual belief. It is argued that this still assigns an essential role to belief in perception, though the belief may be of an attenuated form. The second is Fred Dretske's claim that even attenuated belief may be entirely absent from perception. It is argued that (a) `non-epistemic' perception can be understood only by employing the concept of `epistemic' perception; (b) that the former can occur only partially-i.e., within perceptions that are otherwise epistemic; and (c) that by switching attention from the perception of objects to the Phenomenological tradition's concern with the perception of world, we can see that perception must be entirely permeated with `doxastic' force.

I interpret and defend Sellars’ intemalist view of perceptual justification which argues that perceivers have evidence for their perceptual beliefs that includes a higher-order belief about the circumstances in which those beliefs arise, and an epistemic belief about the reliability of beliefs that are formed in those circumstances. The pattem of inference that occurs in ordinary cases of perception is elicited.I then defend this account of perceptual evidence against 1) AIston’s objection that ordinary perceivers are not as critical and reflective as this view requires them to be; and 2) the charge that intemalism leads to various forms of infinite regress and circular reasoning. It is granted that subjects must have further grounds for their justifying reasons, and an attempt is made to identify these second-order reasons. In particular, I argue that epistemic beliefs are grounded in the perceiver’s awareness that his present experience-cum-conditions fits into a larger pattem of similar past experiences that were reliably connected with their objects.

During the last fifteen years or so there has been much debate, among philosophers interested in perception, on the question of whether the representational content of perceptual experience is conceptual or nonconceptual. Recently, however, a number of philosophers have challenged the terms of this debate, arguing that one of its most basic assumptions is mistaken. Experience, they claim, does not have representational content at all. On the kind of approach they suggest, having a perceptual experience is not to be understood on the model of thought or belief, as a matter of the subject's taking things in the world to be this or that way, or of having this or that feature. Nor is it to be understood on the model of receiving testimony about how things are in the world, as a matter of its being represented to us that things are this or that way. Rather, it is simply a matter of our being presented with things. Having a perceptual experience of an object is a matter of our standing in a certain kind of relation to it which makes it available to us to be represented in thought or belief, but which does not itself involve our representing it, or its being represented to us.1 Much of the motivation for rejecting the view that experience has representational content springs from a concern to do justice to what is distinctive about perceptual experience in contrast to thought and belief. In particular, perceptual experience seems to be more "primitive" than thought, in that it seems natural to appeal to the character of perceptual experience to explain the possibility of thought about objects rather than the other way around. There is thus a concern that we will deprive..

The author argues that coherence views of justification, in spite of their crucial insight into the interpenetration of our beliefs, neglect a key constraint on justification: they are unable to accommodate the epistemic significance of experience. Epistemic justification is not just a function of our beliefs and their interrelations. Both, beliefs and experiences, are relevant to the justification of an empirical belief. Experience is not itself a form of belief or disposition to believe; it cannot be analyzed in doxastic terms. And, yet, nondoxastic experiences play a justificatory role, not merely a causal role. The positive epistemic status of a perceptual belief depends upon being appeared to in appropriate ways. It is important that, for an ordinary perceptual belief to be justified, one does not have to believe that one is appeared to in these ways. It is the experiences themselves, the ways of being appeared to, not our beliefs about them, that are required for justification.

Any theory of perceptual experience should elucidate the way humans exploit it in activities proper to responsible agents, like justifying and revising their beliefs. In this paper I examine the hypothesis that this capacity requires the positing of a perceptual awareness involving a pre-doxastic actualization of concepts. I conclude that this hypothesis is neither necessary nor sufficient to account for empirical rationality. This leaves open the possibility to introduce a doxastic account, according to which the epistemic function of perception is fulfilled by perceptual beliefs. I develop this claim by showing that the doxastic account satisfies a series of intuitive requirements of justification and belief revision.

The paper develops a conception of epistemic warrant as applied to perceptual belief, called "entitlement", that does not require the warranted individual to be capable of understanding the warrant. The conception is situated within an account of animal perception and unsophisticated perceptual belief. It characterizes entitlement as fulfillment of an epistemic norm that is apriori associated with a certain representational function that can be known apriori to be a function of perception. The paper connects anti-individualism, a thesis about the nature of mental states, and perceptual entitlement. It presents an argument that explains the objectivity and validity of perceptual entitlement partly in terms of the nature of perceptual states–hence the nature of perceptual beliefs, which are constitutively associated with perceptual states. The paper discusses ways that an individual can be entitled to perceptual belief through its connection to perception, and ways that entitlement to perceptual belief can be undermined.

Many hold that perception is a source of epistemically basic (direct) belief: for justification, perceptual beliefs do not need positive inferential support from other justified beliefs, especially from beliefs about one’s current sensory episodes. Perceptual beliefs can, however, be defeated or undermined by other things one believes, and so to be justified in the end there must be no undefeated undermining grounds. Similarly for memory and introspection.1..

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 Huemers (Skepticism and the Veil of Perception, 2001) and Bill Brewers (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.
