The Topic: Much work has been done on the nature of perceptual representation. Familiar debates surround questions about the content of perceptual experience, such as: Is the content wide or narrow? Is the content conceptual or non-conceptual? What is the relation between content and phenomenal character? However, a fundamental question that has not received a great deal of attention is what are the admissible contents of perceptual experience? Equivalently, what contents do perceptual experiences have? Or, which objects and properties are represented in perceptual experience?

The 'content view', in slogan form, is 'Perceptual experiences have representational content'. I explain why the content view should be reformulated to remove any reference to 'experiences'. I then argue, against Bill Brewer, Charles Travis and others, that the content view is true. One corollary of the discussion is that the content of perception is relatively thin (confined, in the visual case, to roughly the output of 'mid-level' vision). Finally, I argue (briefly) that the opponents of the content view are partially vindicated, because perceptual error is due to false belief.

In an earlier paper, "Non-conceptual Content and the 'Space of Reasons'", I distinguished two forms of the view that perceptual content is non-conceptual, which I called the 'state view' and the 'content view'. On the latter, but not the former, perceptual states have a different kind of content than do cognitive states. Many have found it puzzling why anyone would want to make this claim and, indeed, what it might mean. This paper attempts to address these questions.

Recently, the thesis that experience is fundamentally a matter of representing the world as being a certain way has been questioned by austere relationalists. I defend this thesis by developing a view of perceptual content that avoids their objections. I will argue that on a relational understanding of perceptual content, the fundamental insights of austere relationalism do not compete with perceptual experience being representational. As it will show that most objections to the thesis that experience has content apply only to accounts of perceptual content on which perceptual relations to the world play no explanatory role. With austere relationalists, I will argue that perceptual experience is fundamentally relational. But against austere relationalists, I will argue that it is fundamentally both relational and representational.

The notion of perceptual content is commonly introduced in the analysis of perception. It stems from an analogy between perception and propositional attitudes. Both kinds of mental states, it is thought, have conditions of satisfaction. I try to show that on the most plausible account of perceptual content, it does not determine the conditions under which perceptual experience is veridical. Moreover, perceptual content must be bipolar (capable of being correct and capable of being incorrect), whereas perception as a mental state is not (if it is veridical, it is essentially so). This has profound consequences for the epistemological view that perception is a source of knowledge. I sktech a two-level epistemology which is consistent with this view. I conclude that the analogy between perception and propositional attitudes, from which the notion of perceptual content is born, may be more misleading than it is usually thought.

Perceptual experiences justify beliefs—that much seems obvious. As Brewer puts it, “sense experiential states provide reasons for empirical beliefs” (this volume, xx). In Mind and World McDowell argues that we can get from this apparent platitude to the controversial claim that perceptual experiences have conceptual content: [W]e can coherently credit experiences with rational relations to judgement and belief, but only if we take it that spontaneity is already implicated in receptivity; that is, only if we take it that experiences have conceptual content. (1994, 162) Brewer agrees. Their view is sometimes called conceptualism; nonconceptualism is the rival position, that experiences have nonconceptual content. One initial obstacle is understanding what the issue is. What is conceptual content, and how is it different from nonconceptual content? Section 1 of this paper explains two versions of each of the rival positions: state (non)conceptualism and content (non)conceptualism; the latter pair is the locus of the relevant dispute. Two prominent arguments for content nonconceptualism—the richness argument and the continuity argument—both fail (section 2). McDowell’s and Brewer’s epistemological defenses of content conceptualism are also faulty (section 3). Section 4 gives a more simple-minded case for conceptualism; finally, some reasons are given for rejecting the claim—on one natural interpretation—that experiences justify beliefs.

The dissertation addresses a debate in the philosophy of perception between conceptualists and nonconceptualists. Its principal thesis is that the intentional content of a perceptual experience is the content of a thought that a reflective subject is in a position to think if she has the experience. I call this claim, endorsed by conceptualists, the thesis of content congruence. Two principal lines of argument are put forward for it. The first, ‘simple’ argument contends that a perceptual experience is a state in which it perceptually appears to the subject that things are thus and so; that a reflective subject who has an experience is in a position to think that things are thus and so; and that the subject in question, in doing so, thinks a thought with the same content as her experience. The second line of argument appeals to the role of perceptual experience in intentional explanation of observational beliefs. It makes the case that such explanation presumes that there is a non-trivial, non-vacuous law linking perceptual experiences with observational beliefs, and argues that an adherent of content congruence is significantly better placed to formulate such a law (consistently with her view) than her ‘content nonconceptualist’ opponent. The thesis of content congruence has often been associated in the literature with the thesis of state conceptualism, i.e. the claim that the representational capacities in virtue of the activation of which a perceptual experience has the content it has are conceptual. I reject the latter, and explain why we should not expect the denial of that claim, i.e. state nonconceptualism, to be incompatible with content congruence. I defend moreover the thesis of content congruence against the objection that it confuses sense and reference, and the objection that it leads to a viciously circular or otherwise inadequate account of observational or demonstrative concepts.

Though it enjoys widespread support, the claim that perceptual experiences possess nonconceptual content has been vigorously disputed in the recent literature by those who argue that the content of perceptual experience must be conceptual content. Nonconceptualism and conceptualism are often assumed to be well-defined theoretical approaches that each constitute unitary claims about the contents of experience. In this paper I try to show that this implicit assumption is mistaken, and what consequences this has for the debate about perceptual experience. I distinguish between two different ways that nonconceptualist (and conceptualist) proposals about perceptual content can be understood: as claims about the constituents that compose perceptual contents or as claims about whether a subject.

In this paper I argue, against recent claims by Bermúdez () and Toribio (), that within the debate about whether perceptual experiences are nonconceptual, ‘state nonconceptualism’ (or the ‘state view’) can be a coherent and plausible position. In particular, I explain that state nonconceptualism and content nonconceptualism, when understood in their most plausible and motivated form, presuppose different notions of content. I argue that state nonconceptualism can present a plausible way of unpacking the claim that perceptual experiences are nonconceptual once the notion of content it should presuppose is taken into account; and once this notion of content is clearly distinguished from the one usually presupposed by content nonconceptualism, the criticisms that Bermúdez and Toribio place against state nonconceptualism become ineffective.
