Which objects and properties are represented in perceptual experience, and how are we able to determine this? The papers in this collection address these questions together with other fundamental questions about the nature of perceptual content. The book draws together papers by leading international philosophers of mind, including Alex Byrne (MIT), Alva Noë (University of California, Berkeley), Tim Bayne (St Catherine’s College, Oxford), Michael Tye (University of Texas, Austin), Richard Price (All Souls College, Oxford) and Susanna Siegel (Harvard University) (...)

Forthcoming (2011) in K. Hawley and F. Macpherson (eds.) The Admissible Contents of Experience, Wiley‐Blackwell. The Admissible Contents of Experience Fiona Macpherson This essay provides an overview of the debate concerning the admissible contents of experience, together with an introduction to the papers in this volume. The debate is one that takes place among advocates of a certain way of thinking of perceptual experiences: that they are states that represent the world. (...) For to say that a state has content is to say that it represents; and its content is usually taken to be that which is represented. One should not be tempted to think that the debate is therefore marginal or esoteric, for this view of perceptual experience has been by far the dominant view of perceptual experience in recent years in philosophy (and in psychology and neuroscience). The debate is about what answer to give to a fundamental question about the nature of perceptual experience, namely: what objects and properties can it represent? (shrink)

My purpose is to take a close look at the nature of visual content. I discuss the view that visual experiences have only existential contents, the view that visual experiences have either singular or gappy contents, and the view that visual experiences have multiple contents. I also consider a proposal about visual content inspired by Kaplan's well known theory of indexicals. I draw out some consequences of my discussion for the thesis of intentionalism with respect to the (...) phenomenal character of visual experience. (shrink)

Debates surrounding the high-level contents of perceptual experience focus on whether weperceive the high-level properties of visual objects, such as the property of being a pine tree. Thispaper considers instead whether we perceive the high-level properties of visual scenes, such asthe property of being a forest. Liberals about the contents of perceptual experience have offered avariety of phenomenal contrast cases designed to reveal how the high-level properties of objectsfigure in our visual experience. I offer a (...) series of equivalent phenomenal contrast cases intendedto show how the high-level properties of visual scenes also figure in visual experience. Thisfirst-person evidence of high-level scene perception is combined with third-person evidence fromthe extensive empirical literature on scene categorisation. Critics of liberalism have attempted todeflate existing phenomenal contrast cases by explaining the contrasts in terms of non-perceptualcontents or in terms of attentional changes. I show that neither response is applicable to mycontrast cases and conclude that we do indeed perceptually experience the high-level propertiesof visual scenes. (shrink)

I address three interrelated issues concerning the contents of experiences. First, I address the preliminary issue of what it means to say that experiences have contents. Then I address the issue of why we should believe that experiences have contents. Finally, I address the issue of what the contents of experiences are.

The on-going debate over the ‘admissible contents of perceptual experience’ concerns the range of properties that human beings are directly acquainted with in perceptual experience. Regarding vision, it is relatively uncontroversial that the following properties can figure in the contents of visual experience: colour, shape, illumination, spatial relations, motion, and texture. The controversy begins when we ask whether any properties besides these figure in visual experience. We argue that ‘ensemble properties’ should be added (...) to the list of visually admissible properties. Ensemble properties are features that belong to a set of perceptible objects as a whole as opposed to the individuals that constitute that set. They include such features as the mean size of an array of shapes or the average emotional expression of an array of faces. Recent work in vision science has yielded compelling evidence that the visual system routinely encodes such properties. We argue that epistemological considerations provide strong reasons to think that these properties figure in visual experience. Judgements about ensemble properties are immediately warranted by our perceptual experience, and the only plausible way that a perceptual experience could confer this warrant is if it confers awareness of ensemble properties.

The nature of perception has long been a central question in philosophy. It is of crucial importance not just in the philosophy of mind, but also in epistemology, metaphysics, aesthetics, and the philosophy of science. The essays in this 1992 volume not only offer fresh answers to some of the traditional problems of perception, but also examine the subject in light of contemporary research on mental content. A substantial introduction locates the essays within the recent history of the subject, and (...) demonstrates the links between them. The Contents of Experience brings together some prominent philosophers in the field, and offers a major statement on a problem central to current philosophical thinking. Notable contributors include Christopher Peacocke, Brian O'Shaughnessy and Michael Tye. (shrink)

Some have claimed that people with very different beliefs literally see the world differently. Thus Thomas Kuhn: ‘what a man sees depends both upon what he looks at and also upon what his previous visual—conceptual experience has taught him to see’ (Kuhn 1970, p. ll3). This view — call it ‘Perceptual Relativism’ — entails that a scientist and a child may look at a cathode ray tube and, in a sense, the first will see it while the second won’t. (...) The claim is not, of course, that the child’s experience is ‘empty’; but that, unlike the scientist, it does not see the tube as a cathode ray tube. One way of supporting this claim is to say that one cannot see something as an F unless one has the concept F. Since the child plainly lacks the concept of a cathode ray tube, it cannot see it as a cathode ray tube. Although Perceptual Relativism is hard to believe, this supporting suggestion is not so implausible. After all, when we see (and more generally, perceive) the world, the world is presented to us in a particular way; so how can we see it as being that way unless we have some idea or conception of the way it is presented? We need not be committed to a representative theory of perception to think that perceptions in some sense represent the world. We can express this by saying that perceptions have content. Now it is a commonplace that the contents of beliefs and the other propositional attitudes involve concepts. The belief that this thing is a cathode ray tube involves, in some sense, the concept cathode ray tube. So the line of thought behind Perceptual Relativism may be expressed thus: seeing an F as an F is a state with content. (shrink)

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. (shrink)

In this paper I aim to situate the Naiyayika theory of perception in contemporary philosophy of mind. Following the ancients, I suggest we reconsider the taxonomy and the assumed interactions between kinds of perceptual content. This reclassification will lead us to reconsider some aspects of the Cartesian conception of mind that continue to influence the work of contemporary theorists. I focus attention on different accounts of sensory perception favoured by ancient Indian Naiyayika philosophers and Descartes as a starting point for (...) reconsidering contemporary accounts of perceptual content.I show that Descartes' account of sensory perception provides the impetus for a causal-explanatory account of conceptual content in terms of its non-conceptual counterpart. Though contemporary philosophers claim to have cast off their Cartesian heritage, my discussion reveals that some of its tenets continue to influence the work of contemporary philosophers. I offer reasons for rejecting yet another Cartesian influence and recommend that we follow the Nyaya taxonomy of perceptual states. (shrink)

We discuss at some length evidence from the cognitive science suggesting that the representations of objects based on spatiotemporal information and featural information retrieved bottomup from a visual scene precede representations of objects that include conceptual information. We argue that a distinction can be drawn between representations with conceptual and nonconceptual content. The distinction is based on perceptual mechanisms that retrieve information in conceptually unmediated ways. The representational contents of the states induced by these mechanisms that are available to (...) a type of awareness called phenomenal awareness constitute the phenomenal content of experience. The phenomenal content of perception contains the existence of objects as separate things that persist in time and time, spatiotemporal information, and information regarding relative spatial relations, motion, surface properties, shape, size, orientation, color, and their functional properties.

Representationalism is the position that the phenomenal character of an experience is either identical with, or supervenes on, the content of that experience. Many representationalists hold that the relevant content of experience is nonconceptual. I propose a counterexample to this form of representationalism that arises from the phenomenon of Gestalt switching, which occurs when viewing ambiguous figures. First, I argue that one does not need to appeal to the conceptual content of experience or to judgements to (...) account for Gestalt switching. I then argue that experiences of certain ambiguous figures are problematic because they have different phenomenal characters but that no difference in the nonconceptual content of these experiences can be identified. I consider three solutions to this problem that have been proposed by both philosophers and psychologists and conclude that none can account for all the ambiguous figures that pose the problem. I conclude that the onus is on representationalists to specify the relevant difference in content or to abandon their position. (shrink)

I defend the thesis that at least some moral properties can be part of the contents of experience. I argue for this claim using a _contrast argument_, a type of argument commonly found in the literature on the philosophy of perception. I first appeal to psychological research on what I call emotionally empathetic dysfunctional individuals to establish a phenomenal contrast between EEDI s and normal individuals in some moral situations. I then argue that the best explanation for this (...) contrast, assuming non-skeptical moral realism, is that _badness_ is represented in the normal individual’s experience but not in the EEDI ’s experience. I consider and reject four alternative explanations of the contrast. (shrink)

The view that the content of experience is conceptual is often felt to conflict with the empiricist intuition that experience precedes thought, rather than vice versa. This concern is explicitly articulated by Ayers as an objection both to McDowell and Davidson, and to the conceptualist view more generally. The paper aims to defuse the objection in its general form by presenting a version of conceptualism which is compatible with empiricism. It proposes an account of observational concepts on which (...) possession of such a concept involves more than the ability for perceptual discrimination, but less than the capacity to employ the concept in inferences: it consists in the capacity to perceptually discriminate objects with the awareness that one is discriminating as one ought. This understanding of concept-possession allows us make sense of experiences' having conceptual content without supposing that the subject must grasp the relevant concepts prior to having those experiences.

To what extent is the external world the way that it appears to us in perceptual experience? This perennial question in philosophy is no doubt ambiguous in many ways. For example, it might be taken as equivalent to the question of whether or not the external world is the way that it appears to be? This is a question about the epistemology of perception: Are our perceptual experiences by and large veridical representations of the external world? Alternatively, the question (...) might be taken as asking whether or not the external world is like its ways of appearing to us, where the expression “ways of appearing” is intended to pick out aspects of our perceptual experiences themselves. This is a metaphysical version of the question of the relationship between appearance and reality: What is the relationship between the phenomenal features that characterize perceptual experience, on the one hand, and the mind-independent features of the external objects of perception, on the other? There are some philosophers who might resist distinguishing between these two questions. For them, “ways of appearing” in the phenomenal sense just are the ways that things appear to be (let’s call the latter the “intentional sense” of “ways of appearing”).1 That is, the phenomenal character of an experience is nothing over and above its representational content. Phenomenal properties are represented properties—the properties that an experience attributes to the external objects of perception. The question of whether or not phenomenal properties can be identified with the represented properties of an experience mirrors traditional questions in the philosophy of perception. If they can be identified with each other, then in veridical perception we might be said to “directly grasp” features of the external world through perception. The properties that are present to the mind are the very same properties that belong to the external objects of perception. Such a view affords.... (shrink)

Both common sense and dominant traditions in art criticism and philosophical aesthetics have it that aesthetic features or properties are perceived. However, there is a cast of reasons to be sceptical of the thesis. This paper defends the thesis—that aesthetic properties are sometimes represented in perceptual experience—against one of those sceptical opponents. That opponent maintains that perception represents only low-level properties, and since all theorists agree that aesthetic properties are not low-level properties, perception does not represent aesthetic properties. I (...) offer a novel argument—what I call the argument from seeing-as—against that sceptic which moves from consideration of ambiguous figures to consideration of visual art. It concludes that aesthetic properties are sometimes perceived and delivers a general lesson for philosophy of perception. Contrary to extant theories of rich perceptual content, aesthetic properties are far better candidates for high-level perceptual contents than standardly theorized rich contents like natural kinds.

I propose a counterexample to naturalistic representational theories of phenomenal character. The counterexample is generated by experiences of novel colours reported by Crane and Piantanida. I consider various replies that a representationalist might make, including whether novel colours could be possible colours of objects and whether one can account for novel colours as one would account for binary colours or colour mixtures. I argue that none of these strategies is successful and therefore that one cannot fully explain the nature of (...) the phenomenal character of perceptual experiences using a naturalistic conception of representation.

Diachronic perceptual atomism is the view that the contents of experience do not involve temporal relations between non-simultaneous events, such as motion, succession, or duration, but only 'snapshots' of the world. Traditionally, atomism has not been a very popular view. Indeed, many philosophers think that it is obviously false and that the main debate about time consciousness takes place between models which reject atomistic commitments. This antiatomistic sentiment can be traced back to William James's slogan that 'a succession (...) of feelings, in and of itself, is not a feeling of succession'. In this paper I argue, first, that the arguments typically launched against atomism in the spirit of James's slogan fail; and second, that the viability of atomism depends on what the conditions for a mental event's being an experience are. In particular, I argue that if a mental event is an experience only if it fulfils certain downstream conditions, which concern the role of the event in the subject's cognitive life, then atomism fails. Otherwise, it is in fact a viable and in many ways attractive view. It follows from my discussion that, contrary to popular belief, atomism is by no means obviously false. Rather, its viability depends on one's further views about the relationship between experience and cognition. (shrink)

What do we see? We are visually conscious of colors and shapes, but are we also visually conscious of complex properties such as being John Malkovich? In this book, Susanna Siegel develops a framework for understanding the contents of visual experience, and argues that these contents involve all sorts of complex properties. Siegel starts by analyzing the notion of the contents of experience, and by arguing that theorists of all stripes should accept that experiences have (...) contents. She then introduces a method for discovering the contents of experience: the method of phenomenal contrast. This method relies only minimally on introspection, and allows rigorous support for claims about experience. She then applies the method to make the case that we are conscious of many kinds of properties, of all sorts of causal properties, and of many other complex properties. She goes on to use the method to help analyze difficult questions about our consciousness of objects and their role in the contents of experience, and to reconceptualize the distinction between perception and sensation. Siegel's results are important for many areas of philosophy, including the philosophy of mind, epistemology, and the philosophy of science. They are also important for the psychology and cognitive neuroscience of vision. (shrink)

I suppose that substantive philosophical theses are much like second marriages. The philo- sophical thesis I wish to discuss in this paper is the thesis that experiences have nonconceptual content. I shall not attempt to argue that _all_ experiences have nonconceptual content nor that the only contents experiences have are nonconceptual. Instead, I want to ? esh out the thesis of nonconceptual content for experience in more detail than has been offered hithertofore and to provide a variety of (...) motivations for the view. (shrink)

The intentionalist about consciousness holds that the qualitative character of experience.

This paper examines the representationalist view of experiences in the light of the phenomena of perfect and relative pitch. Two main kinds of representationalism are identified - environment-based and cognitive role-based. It is argued that to explain the relationship between the two theories a distinction should be drawn between various types of implicit and explicit content. When investigated, this distinction sheds some light on the difference between the phenomenology of perfect and relative pitch experiences and may be usefully applied to (...) describe the nature of experiences in the other sense modalities. (shrink)

The intentionalist about consciousness holds that the qualitative character of experience, “what it’s like,” is determined by the contents of a select group of special intentional states of the subject. Fred Dretske (1995), Mike Thau (2002), Michael Tye (1995) and many others have embraced intentionalism, but these philosophers have not generally appreciated that, since we are intimately familiar with the qualitative character of experience, we thereby have special access to the nature of these contents. In this (...) paper, we take advantage of this fact to show that intentionalism is incompatible with the idea that these contents are singular or general propositions, and thus that intentionalism is incompatible with one dominant trend in thinking about contents in general. In particular, there appear to be insoluble difficulties in explaining how the phenomenology of place and time can be explained by any intentionalist theory appealing to singular or general propositions.

This paper examines the contents of perceptual experience, and focuses in particular on the relation between the representational aspects of an experience and its phenomenal character. It is argued that the Critical Realist two-component analysis of experience, advocated by Wilfrid Sellars, is preferable to the Intentionalist view. Experiences have different kinds of representational contents: both informational and intentional. An understanding of the essential navigational role of perception provides a principled way of explaining the nature of (...) such representational contents. Experiences also have a distinct phenomenal content, or character, which is not determined by representational content. (shrink)

Crane's volume collects nine essays ranging over an impressive number of fundamental problems of perception. One unique feature of this volume is captured in Crane's hope that "some of the essays in this volume show that there is much that is worth recovering from the sense-data tradition".

How can we discover the contents of experience? I argue that neither introspection alone nor naturalistic theories of experience content are sufficient to discover these contents. I propose another method of discovery: the method of phenomenal contrast. I defend the method against skeptics who doubt that the contents of experience can be discovered, and I explain how the method may be employed even if one denies that experiences have contents.

In this paper I discuss several proposals for how to find out which contents visual experiences have, and I defend the method I.

Integrated information theory attempts to account for both the quantitative and the phenomenal aspects of consciousness, and in taking consciousness as fundamental and widespread it bears similarities to panpsychist Russellian monism. In this paper I compare IIT's and RM's response to the conceivability argument, and their metaphysical account of conscious experience. I start by claiming that RM neutralizes the conceivability argument, but that by virtue of its commitment to categoricalism it doesn't exclude fickle qualia scenarios. I argue that IIT's (...) core notion of intrinsic cause-effect power makes it incompatible with categoricalist versions of RM and, to the contrary, is best understood as entailing pandispositionalism, the view for which all properties are powers. I show that, thus construed, IIT can cope with both the conceivability and with the fickle qualia arguments, offers a promising way to account for the content of experience, and hence is preferable to categoricalist RM.
