The Contents of Perception, Misc

Discourse containing the verb ‘feel’, almost without exception, purports to describe inner experience. Though this much is evident, the question remains what exactly is conveyed when we talk about what and how we feel? Does discourse containing the word ‘feel’ actually succeed in describing the content and phenomenology of inner experience? If so, how does it reflect the phenomenology and content of the experience it describes? Here I offer a linguistic analysis of ‘feels’ reports and argue that a subset of (...) ‘feels’ reports, when accurate, reflect the representational content of emotions, tactile experiences and bodily sensations. Because ‘feels’ reports may reflect the representational content of bodily experience, these types of report may be able to give us some insight into the structure of bodily experience. I argue that our descriptions of bodily experience, on the assumption that they are sometimes accurate, indicate that emotions and tactile experiences are experiences of bodily reactions to objects, whereas bodily sensations are partial descriptions of emotions and tactile experiences or other events of the body. At the end I address the concern that an adequate account of inner experience cannot be given in terms of an analysis of ordinary language. (shrink)

Roderick Chisholm argued that ‘look’ can be used in three different ways: epistemically, comparatively and non-comparatively. Chisholm’s non-comparative sense of ‘look’ played an important role in Frank Jackson’s argument for the sense-datum theory. The question remains..

The article provides the state of the art on the debate about whether the logical form of ‘look’ statements commits us to any particular theory of perceptual experience. The debate began with Frank Jackson’s (1977) argument that ‘look’ statements commit us to a sense-datum theory of perception. Thinkers from different camps have since then offered various rejoinders to Jackson’s argument. Others have provided novel arguments from considerations of the semantics of ‘look’ to particular theories of perception. The article closes with (...) an argument of this sort for a representational theory of perceptual experience. (shrink)

A number of authors have asked what it takes for a course of mental imagery to be epistemically or practically useful. This paper addresses a prior question, namely, the difference between courses of imagination that are realistic and those that are fantastic. One approach, suggested by recent literature concerning the utility of imagery, holds that a course of imagination represents realistically if and only if the course of events represented conforms to certain accepted constraints. Against this it will be argued (...) that the constraints cannot be both permissive enough and restrictive enough. An alternative approach adds as a necessary condition that realistic courses of imagination are constructed in accordance with certain procedures on the basis of remembered perceptions. (shrink)

I argue that there are no irrational visual experiences, if we mean just the experiences that one is having now, but there are irrational visual experiences, if we mean also the experiences that one has had in the past. In other words, I will be arguing that perceptual irrationality is a retrospective phenomenon. So as to further support the first conjunct of my thesis, and to contextualize it among contemporary discussions, I also critique Susanna Siegel’s proposal that one could be (...) having an irrational experience, in the sense of a hijacked experience that has inherited a sub-threshold epistemic charge from a corrupt outlook. The present discussion is conducted from a Husserlian point of view, according to which perception is rational, rather than arational. I am, however, in this paper, not undertaking to defend the Husserlian view or the rationality of perception, or even to argue that the view I refer to as Husserlian is, in all aspects, the view that Edmund Husserl actually held. I aim merely to provide certain clarifications concerning the more specific topic of irrational visual experiences. (shrink)

Both John Campbell and Quassim Cassam have argued that we perceptually experience objects as mind-independent (MI), purportedly solving a problem they refer to as “Berkeley’s Puzzle.” In this paper, I will consider the same topic from a Husserlian perspective. In particular, I will clarify the idea of MI and argue that there is, indeed, a sense in which we can perceptually experience objects as MI, while also making objections to Campbell’s and Cassam’s respective arguments to the same effect. In particular, (...) I will argue that objects can be experienced as MI in the sense of the experience’s not being due to the malfunctioning of a perceptual organ, e.g., when one examines the ways in which the object displays itself, and gains confidence that there is, indeed, nothing the matter with one’s eyes. I will address the issue of MI from the perspective of Husserlian evidentialism, according to which perceptual content is conceived in terms of ways of perceptually exploring the object, thereby gaining evidence pertinent to the object and its properties, e.g., as when one takes a look at the object’s shape from a different angle, or scrutinizes its color in better lighting. (shrink)

In this paper, I put forward an argument for the view that emotional responses of esteem to perceived demonstrations of good character represent the perceived character traits as valuable, and hence, as virtues. These esteeming experiences are analogous to perceptual representations in other modalities in their epistemic role as causing, providing content for and justifying beliefs regarding the value of the traits they represent. I also discuss the role that the perceiver’s own character plays in their ability to recognize and (...) respond appropriately to virtue in others, showing that moral virtues are also epistemic virtues when it comes to facilitating knowledge about the character of people we encounter. (shrink)

Perceptual Confidence is the view that our conscious perceptual experiences assign degrees of confidence. In previous papers, I motived it using first-personal evidence (Morrison 2016) and Jessie Munton motivated it using normative evidence (Munton 2016). In this paper, I will consider the extent to which it is motivated by third-personal evidence. I will argue that the current evidence is supportive but not decisive. I will also describe experiments that might provide more decisive evidence.

Casey O’Callaghan has argued that rather than hearing meanings, we hear phonemes. In this note I argue that valuable though they are in an account of speech perception – depending on how we define ‘hearing’ – phonemes either don’t explain enough or they go too far. So, they are not the right tool for his criticism of the semantic perceptual account (SPA).

Some have defended a Fregean view of perceptual content. On this view, the constituents of perceptual contents are Fregean modes of presentation (MOPs). In this paper, I propose that perceptual MOPs are best understood in terms of object files. Object files are episodic representations that store perceptual information about objects. This information is updated when sensory conditions change. On the proposed view, when a subject perceptually represents some object a under two distinct MOPs, then the subject initiates two object files (...) that both refer to a. My defense of this view appeals to its satisfaction of four constraints that I argue theories of perceptual MOPs should satisfy. Furthermore, I show that some existent accounts of perceptual MOPs fail to satisfy them. The defended constraints also indicate what is unique about perceptual, as opposed to linguistic or cognitive, MOPs. (shrink)

Keith has just taken a hallucinogenic drug. A few minutes earlier, he was occupied with the beginning of H.H. Price's well-known book on perception. The combined effect of these activities is that Keith is now hallucinating a ripe tomato. This is not a de re hallucination. There is no particular tomato located elsewhere out of Keith's vision such that he is hallucinating that tomato as being before him. Keith is hallucinating a tomato without there being any particular tomato that he (...) is hallucinating. What is the representational content of Keith‟s experience? (shrink)

Tomamos como certo que os nossos sentidos nos colocam em contato com o ambiente ao nosso redor. Enquanto caminhamos em uma rua, vemos obstáculos que temos de contornar ou remover. Mesmo de costas, podemos ouvir a bicicleta que se aproxima e dar passagem. Em suma, por meio de experiências perceptivas (visuais, auditivas, olfativas etc.), ficamos conscientes de objetos ou eventos que estejam ocorrendo ao nosso redor. Além disso, com base no que percebemos, podemos formar e manter crenças acerca do ambiente (...) e, assim, adquirir conhecimento perceptivo acerca do mundo. A importância desse conhecimento acerca do que está ao nosso alcance perceptivo é inestimável para a nossa sobrevivência e a condução de nossos projetos cotidianos. Contudo, podemos querer saber (1) se de fato temos acesso ao mundo físico circundante por meio das nossas experiências perceptivas, e (2) se e como essas experiências justificam as nossas crenças acerca do que percebemos. Esses problemas são centrais para a epistemologia da percepção, embora não sejam os únicos. Nessa entrada, abordaremos esses dois problemas. (shrink)

In this paper, I provide an account of the spatiality of olfactory experiences in terms of topological properties. I argue that thinking of olfactory experiences as making the subject aware of topological properties enables us to address popular objections against the spatiality of smells, and it makes sense of everyday spatial olfactory phenomenology better than its competitors. I argue for this latter claim on the basis of reflection on thought experiments familiar from the philosophical literature on olfaction, as well as (...) on the basis of some empirical data about the localization of smells. I conclude by suggesting how the naïve‐topology framework could be applied in debates about the spatiality of other types of experiences. (shrink)

One of the most influential traditional objections to Adverbialism about perceptual experience is that posed by Frank Jackson’s ‘many property problem’. Perhaps largely because of this objection, few philosophers now defend Adverbialism. We argue, however, that the essence of the many property problem arises for all of the leading metaphysical theories of experience: all leading theories must simply take for granted certain facts about experience, and no theory looks well positioned to explain the facts in a straightforward way. Because of (...) this, the many property problem isn’t on its own a good reason for rejecting Adverbialism; and nor is it a puzzle that will decide amongst the other leading theories. (shrink)

Four experiments investigated the extent to which abstract quantitative information can be conveyed by basic visual features. This was done by asking observers to estimate and discriminate Pearson correlation in graphical representations where the first data dimension of each element was encoded by its horizontal position, and the second by the value of one of its visual features; perceiving correlation then requires combining the information in the two encodings via a common abstract representation. Four visual features were examined: luminance, color, (...) orientation, and size. All were able to support the perception of correlation. Indeed, despite the strikingly different appearances of the associated stimuli, all gave rise to performance that was much the same: just noticeable difference was a linear function of distance from complete correlation, and estimated correlation a logarithmic function of this distance. Performance differed only in regards to the level of noise in the feature, with these values compatible with estimates of channel capacity encountered in classic experiments on absolute perceptual magnitudes. These results suggest that quantitative information can be conveyed by visual features that are abstracted at relatively low levels of visual processing, with little representation of the original sensory property. It is proposed that this is achieved via an abstract parameter space in which the values in each perceptual dimension are normalized to have the same means and variances, with perceived correlation based on the shape of the joint probability density function of the resultant elements.

Visual perception is widely taken to present properties such as redness, roundness, and so on. This in turn might be thought to give rise to accuracy conditions for experience, and so content, regardless of which metaphysical view of perception one endorses. An influential version of this argument—Susanna Siegel’s ’Argument from Appearing’—aims to establish the existence of content as common ground between representational and relational views of perception. This goes against proponents of ‘austere’ relationalism who deny that content plays a substantive (...) role in philosophical explanations of conscious perceptual experience. Though Siegel’s argument purports to be neutral with respect to the metaphysics of perception, it relies upon an equivocation between the presentation of property-types and property-instances. Consequently, the argument begs the question against the austere relational view, and so fails to establish the desired conclusion. So while relationalists can and should allow that experiences have accuracy conditions, it does not follow from this that they have contents of any philosophically interesting or significant kind.

A number of philosophers have held that we visually experience objects’ occluded parts, such as the out-of-view exterior of a voluminous, opaque object. That idea is supposed to be what best explains the fact that we see objects as whole or complete despite having only a part of them in view at any given moment. Yet, the claim doesn’t express a phenomenological datum and the reasons for thinking we do experience objects’ occluded parts, I argue, aren’t compelling. Additionally, I anticipate (...) and reply to attempts to salvage the idea by appeal to perceptual expectation and amodal completion. Lastly, I address potential concerns that the only way to capture the phenomenal character of perceiving voluminous objects is to say experience outstrips what’s in view, providing a description of such experience without any implication of that idea. (shrink)

In this paper, I propose a Husserlian account of perceptual confidence, and argue for perceptual confidence by appeal to the self-justification of perceptual experiences. Perceptual confidence is the intriguing view, recently developed by John Morrison, that there are not just doxastic confidences but also perceptual confidences, i.e., confidences as aspect of perceptual experience, enabling us to account, e.g., for the increasing confidence with which we experience an approaching human figure, while telling ourselves, as the viewing distance diminishes, “It looks like (...) this just could be Isaac”, “It looks like this is probably Isaac”, “It looks like this is almost certainly Isaac”. I first present my Husserlian account with a focus on the notion of fulfillment, and the idea that the contents of perceptual experience are fulfillment conditions. I then show that this account can be complemented by PC. Finally, I develop a focus on the idea of perceptual self-justification, diverting the perceptual confidence debate from its pre-eminent concern with the relations between perceptual and doxastic confidences, and present an argument to the effect that there are perceptual confidences. (shrink)

John Morrison has argued that confidences are assigned in perceptual experience. For example, when you perceive a figure in the distance, your experience might assign a 55-percent confidence to the figure’s being Isaac. Morrison’s argument leans on the phenomenon of ‘completely trusting your experience’. I argue that Morrison presupposes a problematic ‘importation model’ of this familiar phenomenon, and propose a very different way of thinking about it. While the article’s official topic is whether confidences are assigned in perceptual experience, it (...) is also about two more general issues: how we can determine which properties are assigned in perceptual experience; and how we transition from perception to belief. (shrink)

Husserl’s transcendental phenomenology is first and foremost a science of the structures of consciousness. Since it is intended to yield eidetic, i. e., a priori insights, it is often assumed that transcendental phenomenology and the natural sciences are totally detached from each other such that phenomenological investigations cannot possibly benefit from empirical evidence. The aim of this paper is to show that a beneficial relationship is possible. To be more precise, I will show how Husserl’s a priori investigations on consciousness (...) can be supplemented by research in experimental psychology in order to tackle fundamental questions in epistemology. Our result will be a phenomenological conception of experiential justification that is in accordance with and supported by empirical phenomena such as perceptual learning and the phenomenon of blindsight. Finally, I shall shed light on the systematic limits of empirical research. (shrink)

Malebranche holds that visual experience represents the size of objects relative to the perceiver's body and does not represent objects as having intrinsic or nonrelational spatial magnitudes. I argue that Malebranche's case for this body-relative thesis is more sophisticated than other commentators—most notably, Atherton and Simmons —have presented it. Malebranche's central argument relies on the possibility of perceptual variation with respect to size. He uses two thought experiments to show that perceivers of different sizes—namely, miniature people, giants, and typical human (...) beings—can experience the very same objects as having radically different sizes. Malebranche argues that there is no principled reason to privilege one of these ways of experiencing size over the others and, more specifically, that all three kinds of perceivers experience size veridically. From the possibility of this kind of veridical perceptual variation, Malebranche infers that visual experience represents only body-relative size. (shrink)

The paper presents a new theory of perceptual demonstrative thought, the property-dependent theory. It argues that the theory is superior to both the object-dependent theory (Evans, McDowell) and the object-independent theory (Burge).

When we imaginatively picture what might happen, we may take what we imagine to be either realistic or fantastic. A wine glass falling to the floor and shattering is realistic. A wine glass falling and morphing into a bird and flying away is fantastic. What does the distinction consist in? Two important necessary conditions are here defined. The first is a condition on the realistic representation of spatial configuration, grounded in an account of the imagistic representation of spatial configuration. The (...) second is a condition on the manner in which realistic courses of mental imagery may be grounded in remembered perceptions. This is defined in terms of an account of the representation of comparative similarity. This is an open access publication. (shrink)

Nick Shea’s Representation in Cognitive Science commits him to representations in perceptual processing that are about probabilities. This commentary concerns how to adjudicate between this view and an alternative that locates the probabilities rather in the representational states’ associated “attitudes”. As background and motivation, evidence for probabilistic representations in perceptual processing is adduced, and it is shown how, on either conception, one can address a specific challenge Ned Block has raised to this evidence.

In his paper “Double Vision, Phosphenes and Afterimages: Non-Endorsed Representations rather than Non-Representational Qualia,” Işık Sarıhan addresses the debate between strong representationalists and qualia theorists. He argues that qualia theorists like Ned Block and Amy Kind who cite double-vision, afterimages, etc., as evidence for the existence of qualia are mistaken about the actual nature of these states. According to Sarıhan, these authors confuse the fact that these states are non-endorsed representational states with the fact that they are at least partly (...) non-representational. I argue that Sarıhan’s argument contains gaps that suggest that he misidentifi es the mistake that leads these qualia theorists to their conclusion. In my view, these qualia theorists do not confuse the fact that the states in question are non-endorsed states with the fact that they are non-representational, but rather mistake certain representational contents, or certain aspects of these contents, for qualia.

A central claim in contemporary philosophy of mind is that the phenomenal character of experience is entirely determined by its content. This paper considers an alternative called Mode Intentionalism. According to this view, phenomenal character outruns content because the intentional mode contributes to the phenomenal character of the experience. I assess a phenomenal contrast argument in support of this view, arguing that the cases appealed to allow for interpretations which do not require positing intentional modes as phenomenologically manifest aspects of (...) experience. (shrink)

In this chapter I introduce the thesis that perceptual appearances are cognitively penetrable and analyse cases made against phenomenal conservatism hinging on this thesis. In particular, I focus on objections coming from the externalist reliabilist camp and the internalist inferentialist camp. I conclude that cognitive penetrability doesn’t yield lethal or substantive difficulties for phenomenal conservatism.

In this paper I will present a puzzle about visual appearance. There are certain necessary constraints on how things can visually appear. The puzzle is about how to explain them. I have no satisfying solution. My main thesis is simply that the puzzle is a puzzle. I will develop the puzzle as it arises for representationalism about experience because it is currently the most popular theory of experience and I think it is along the right lines. However, everyone faces a (...) form of the puzzle, including the naïve realist. In §1 I explain representationalism about experience. In §§2-3 I develop the puzzle and criticize a response due to Ned Block and Jeff Speaks and another response based on a novel form of representationalism (“sensa representationalism”). In §4 I argue that defenders of “perceptual confidence” (Morrison, Munton, my earlier self) face an instance of the puzzle. In §5 I suggest that everyone faces a form of the puzzle. (shrink)

According to the recent Perceptual Confidence view, perceptual experiences possess not only a representational content, but also a degree of confidence in that content. The motivations for this view are partly phenomenological and partly epistemic. We discuss both the phenomenological and epistemic motivations for the view, and the resulting account of the interface between perceptual experiences and degrees of belief. We conclude that, in their present state of development, orthodox accounts of perceptual experience are still to be favoured over the (...) perceptual confidence view. (shrink)

Kendall Walton’s project in ‘Categories of Art’ (1970) is to answer two questions. First, does the history of an artwork’s production determine its aesthetic properties? Second, how – if at all – should knowledge of the history of a work’s production influence our aesthetic judgments of its properties? While his answer to the first has been clearly understood, his answer to the second less so. Contrary to how many have interpreted Walton, such knowledge is not necessary for making aesthetic judgments; (...) perceiving an artwork as belonging to a (correct) category of art requires no art-historical knowledge whatsoever. Moreover, contextualist attempts to incorporate art-historical knowledge via the mechanism of cognitive penetration are incompatible with Walton’s claim that categories of art must be perceptually distinguishable. Here I propose a way of elaborating Walton’s view that avoids this difficulty and reconciles contextualism with aesthetic perception, the view that we perceive aesthetic properties. (shrink)

Pure representationalism or intentionalism for phenomenal experience is the theory that all introspectible qualitative aspects of a conscious experience can be analyzed as qualities that the experience non-conceptually represents the world to have. Some philosophers have argued that experiences such as afterimages, phosphenes and double vision are counterexamples to the representationalist theory, claiming that they are non- representational states or have non-representational aspects, and they are better explained in a qualia-theoretical framework. I argue that these states are fully representational states (...) of a certain kind, which I call “automatically non-endorsed representations”, experiential states the veridicality of which we are almost never committed to, and which do not trigger explicit belief or disbelief in the mind of the subject. By investigating descriptive accounts of afterimages by two qualia theorists, I speculate that the mistaken claims of some anti-representationalists might be rooted in confusing two senses of the term “seeming”.

Can perceptual experiences be states of uncertainty? We might expect them to be, if the perceptual processes from which they're generated, as well as the behaviors they help produce, take account of probabilistic information. Yet it has long been presumed that perceptual experiences purport to tell us about our environment, without hedging or qualifying. Against this long-standing view, I argue that perceptual experiences may well occasionally be states of uncertainty, but that they are never probabilistically structured. I criticize a powerful (...) line of reasoning that we should expect perceptual experience to be probabilistic, given their interfaces with unconscious probabilistic information, with behavior responsive to it, and with credences.

A visual experience, as understood here, is a sensory event that is conscious, or like something to undergo. This chapter focuses on three issues concerning such experiences. The first issue is the so-called ‘transparency’ of experiences. The chapter distinguishes a number of different interpretations of the suggestion that visual experiences are ‘transparent’. It then discusses in what sense, if any, visual experiences are ‘transparent’, and what further conclusions one can draw from that. The second issue is which properties we are (...) presented with in visual experiences. It is widely accepted that we sometimes experience red for example. But exactly which properties do we sometimes visually experience, and which properties do we never visually experience? The third issue is which particulars, if any, we are presented with in visual experiences. Do we for example sometimes visually experience mind-independent particulars like trees? Do we sometimes visually experience mind-dependent, particular ‘sense-data’? (shrink)

According to ecological psychology, animals perceive not just the qualities of things in their environment, but their affordances: in James Gibson’s words, ’what things furnish, for good or ill’. I propose a metaphysics for affordances that fits into a contemporary anti-Humean metaphysics of powers or potentialities. The goal is to connect two debates, one in the philosophy of perception and one in metaphysics, that stand to gain much from each other.

In Mind and World, John McDowell provided an influential account of how perceptual experience makes knowledge of the world possible. He recommended a view he called “conceptualism”, according to which concepts are intimately involved in perception and there is no non‐conceptual content. In response to criticisms of this view (especially those from Charles Travis), McDowell has more recently proposed a revised account that distinguishes between two kinds of representation: the passive non‐propositional contents of perceptual experience – what he now calls (...) “intuitional content” – and the propositional contents of judgment – what he now calls “discursive content.” In this paper, I criticize McDowell's account of intuitional content. I argue that he equivocates between two different notions of intuitional content. These views propose different, and incompatible, ways of understanding how a perceiver makes a judgment based on perceptual experience. This is because these two views result from an underlying indeterminacy as to what, if anything, McDowell now means by “conceptual” when he makes claims that intuitional content is conceptual.

Does time seem to pass, even though it doesn’t, really? Many philosophers think the answer is ‘Yes’—at least when ‘time’s passing’ is understood in a particular way. They take time’s passing to be a process by which each time in turn acquires a special status, such as the status of being the only time that exists, or being the only time that is present. This chapter suggests that, on the contrary, all we perceive is temporal succession, one thing after another, (...) a notion to which modern physics is not inhospitable. The contents of perception are best described in terms of ‘before’ and ‘after’, rather than ‘past’, ‘present, and ‘future’. (shrink)

Terence Horgan and John Tienson argue that there is phenomenal intentionality, i.e., “a kind of intentionality, pervasive in human mental life, that is constitutively determined by phenomenology alone” (p. 520). However, their arguments are open to two lines of objection. First, Horgan and Tienson are not sufficiently clear as to what kind of content it is that they take to be determined by, or to supervene on, phenomenal character. Second, critics have objected that, for their conclusion to follow, Horgan and (...) Tienson would first have to establish the co-variation of phenomenology and intentional content, but even so, phenomenal intentionality would still emerge as less plausible than its converse, representationalism. I will address these two challenges by appeal to Husserlian ideas. A consideration of perceptual phenomenology (i.e., phenomenal character) shows that there is a kind of perceptual content that is, indeed, determined by phenomenal character. Such content is conceived in terms of fulfillment conditions, or what it takes to bring aspects of objects and scenes to different, and more complete, ways of givenness. We can establish the primacy of phenomenology, relative to such fulfillment-conditional content, by tracing it back to the basic phenomenology of visual and other sensations. (shrink)

Brogaard's book is extremely informative about the grammar of perceptual verbs, and questions that it indicates representationalism (as opposed to naive realism). As useful as this is, I question how much grammar tells us much about perception.

A review of Michael Madary's book Visual Phenomenology.

Russell’s theory of acquaintance construes perceptual awareness as at once constitutively independent of conceptual thought and yet a source of propositional knowledge. Wilfrid Sellars, John McDowell, and other conceptualists object that this is a ‘myth’: perception can be a source of knowledge only if conceptual capacities are already in play therein. Proponents of a relational view of experience, including John Campbell, meanwhile voice sympathy for Russell’s position on this point. This paper seeks to spell out, and defend, a claim that (...) offers the prospects for an attractive, unacknowledged element of common ground in this debate. The claim is that conceptual capacities, at least in a certain minimal sense implicit in McDowell’s recent work, must be operative in perceptual experience, if it is to rationalize judgement. The claim will be supported on the basis of two premises, each of which can be defended drawing, inter alia, on considerations stressed by Campbell. First, that experience rationalizes judgement only if it is attentive. Second, that attention qualifies as a conceptual capacity, in the noted, minimal sense. The conjunction of the two premises might be dubbed ‘attentional conceptualism’. (shrink)

Nearly every theory of perception just focuses on one sense at a time; but most of the time we perceive using multiple senses. Casey O'Callaghan offers a revisionist multisensory philosophy of perception: he explores how our senses work together and influence each other, leading to surprising perceptual illusions and novel forms of experience.

My contribution to the first round of a tetralog with Bill Brewer, Anil Gupta, and John McDowell. Each of us has written a response to the writings of the other three philosophers on the topic "Empirical Reason". My initial contribution focuses on what we know a priori about perception. In the second round, we will each respond to the each writer's first-round contributions.

Restrictivists hold that visual experience only represents low-level properties such as shape, spatial location, motion, color, etc. Expansionists contend that visual experience also represents high-level properties such as being a pine tree. I outline a new approach to support expansionism called the conflict cross-modal argument. What I call the conflict cross-modal effects occur when at least two perceptual systems disagree about some property belonging to a common stimulus, and this disagreement causes a change in the representational and phenomenal content of (...) the perceptual experience associated with one, or both, modalities. The conflict cross-modal argument works by accepting that if a property figures in a conflict cross-modal effect, then prima facie that property is a strong common sensible between the two modalities, and vision and another modality disagree about a property that is high-level for vision. After outlining this argument, and showing how it overcomes two obstacles that face traditional methods employed to defend expansionism, I turn to the well known Mcgurk effect as a case where vision and audition disagree about phoneme properties in order to employ my argument for the conclusion that phoneme properties are represented in visual experience. The upshot is that since phoneme properties are high-level for vision, we have an argument supporting expansionism. (shrink)

Olfaction represents odors, if it represents anything at all. Does olfaction also represent ordinary objects like cheese, fish and coffee-beans? Many think so. This paper argues that it does not. Instead, we should affirm an austere account of the intentional objects of olfaction: olfactory experience is about odors, not objects. Visuocentric thinking about olfaction has tempted some philosophers to say otherwise.
