I argue that the transparency of experience provides the basis of arguments both for intentionalism -- understood as the view that there is a necessary connection between perceptual content and perceptual phenomenology -- and for the view that the contents of perceptual experiences are Russellian propositions. While each of these views is popular, there are apparent tensions between them, and some have thought that their combination is unstable. In the second half of the paper, I respond to these worries by (...) arguing that Russellianism is consistent with intentionalism, that their conjunction is consistent with both internalism about phenomenology and externalism about perceptual content, and that the resulting view receives independent support from the relationship between hallucination and thought.

Even if spectrum inversion of various sorts is possible, spectrum inversion without a difference in representation is not. So spectrum inversion does not pose a challenge for the intentionalist thesis that, necessarily, within a given sense modality, if two experiences are alike with respect to content, they are also alike with respect to their phenomenal character. On the contrary, reflection on variants of standard cases of spectrum inversion provides a strong argument for intentionalism. Depending on one’s views about the possibility (...) of spectrum inversion, the impossibility of spectrum inversion without a difference in representation can also be used as an argument against a variety of reductive theories of mental representation.

Replies to critics (Janet Levin, Casey O'Callaghan, and Adam Pautz) for a book symposium on _The Phenomenal and the Representational_.

Summary of the main claims of _The Phenomenal and the Representational_ for a book symposium in PPR. The critics were Janet Levin, Adam Pautz, and Casey O'Callaghan.

In the first part of the paper I try to explain why the disjunctive theory of perception can seem so counterintuitive by focusing on two of the standard arguments against the view-the argument from subjective indiscriminability and the causal argument. I suggest that by focusing on these arguments, and in particular the intuitions that lie behind them, we gain a clearer view of what the disjunctive theory is committed to and why. In light of this understanding, I then present an (...) argument for the disjunctive theory based on the claim that the content of experience is particular and not general. (shrink)

In the present paper, I shall argue that disjunctively construed naïve realism about the nature of perceptual experiences succumbs to the empirically inspired causal argument. The causal argument highlights as a first step that local action necessitates the presence of a type-identical common kind of mental state shared by all perceptual experiences. In a second step, it sets out that the property of being a veridical perception cannot be a mental property. It results that the mental nature of perceptions must (...) be exhausted by the occurrence of inner sensory experiences that narrowly supervene on the perceiver. That is, empirical objects fail directly to determine the perceptual consciousness of the perceiver. The upshot is that not only naïve realism, but also certain further forms of direct realism have to be abandoned. (shrink)

Defending a form of naïve realism about visual experiences is quite popular these days. Those naïve realists who I will be concerned with in this paper make a central claim about the subjective aspects of perceptual experiences. They argue that how it is with the perceiver subjectively when she sees worldly objects is literally determined by those objects. This way of thinking leads them to endorse a form of disjunctivism, according to which the fundamental psychological nature of seeings and hallucinations (...) is distinct. I will oppose their central claim by defending a version of the so-called ‘causal argument’, which dwells on ideas about causation and explanation in perception. The aim of this discussion is to highlight that the subjective aspects of perceptual experiences cannot be explained in naïve realist terms. Instead, it will be argued that one needs to appeal to a mental factor which does not involve worldly objects as constituents, and which is common to seeings and hallucinations. (shrink)

I defend a perceptual account of face-to-face mindreading. I begin by proposing a phenomenological constraint on our visual awareness of others' emotional expressions. I argue that to meet this constraint we require a distinction between the basic and non-basic ways people, and other things, look. I offer and defend just such an account.

In this paper, I argue that perception justifies belief about the external world in virtue of its phenomenal character together with its relations to the external world. But I argue that perceptual relations to the external world impact on the justifying role of perception only by virtue of their impact on its representational content. Epistemic level-bridging principles provide a principled rationale for avoiding more radically externalist theories of perceptual justification.

Most representationalists argue that perceptual experience has to be representational because phenomenal looks are, by themselves, representational. Charles Travis argues that looks cannot represent. I argue that perceptual experience has to be representational due to the way the visual system works.

I develop a view of perception that does justice to Price's intuition that all sensory experience acquaints us with sensible qualities like colour and shape. Contrary to the received opinion, I argue that we can respect this intuition while insisting that ordinary perception puts us in direct contact with the mind-independent world. In other words, Price's intuition is compatible with naïve realism. Both hallucinations and ordinary perceptions acquaint us with instances of the same kinds of sensible qualities. While the instances (...) in hallucination are mind-dependent, those in veridical perception are not. The latter are ontologically over-determined —they have their existence guaranteed both in virtue of having a material bearer and in virtue of being perceived by a mind. Such over-determined instances are mind-independent—they can continue to exist unperceived, because, in addition to the minds that perceive them, their existence is guaranteed by the material objects that are their bearers. (shrink)

There is a straightforward view of perception that has not received adequate consideration because it requires us to rethink basic assumptions about the objects of perception. In this paper, I develop a novel account of these objects—the sensible qualities—which makes room for the straightforward view. I defend two primary claims. First, I argue that qualities like color and shape are “ontologically flexible” kinds. That is, their real definitions allow for both physical objects and mental entities to be colored or shaped. (...) Second, a single instance of these qualities can be attributed to more than one entity. Just as we attribute the same instance of a material property to a statue and to the clay that constitutes it, single instances of sensible qualities should be attributed both to the physical objects perceived and to the perceptual states that have those instances as their objects.

En su caracterización del contenido no conceptual, Christopher Peacocke realiza un esfuerzo constante por diferenciar el contenido no conceptual protoproposicional que propone del contenido de tipo conceptual. En este trabajo analizaré tales esfuerzos para concluir que resultan infructuosos, llevando al autor a lo que podría denominarse como una rotulación incorrecta del contenido protoproposicional como no conceptual. Para ello, reconstruiré la posición no conceptualista de Peacocke y señalaré, mediante los ejemplos que el mismo autor ofrece, la gran similitud que existe entre (...) ciertos contenidos y procesos paradigmáticamente conceptuales, y los ejemplos de contenidos y procesos que el autor considera como protoproposicionales y presuntamente no conceptuales.

This paper is a new defense of the view that visual hallucinations lack content. The claim is that visual hallucinations are illusory not because their content is nonveridical, but rather because they seem to represent when they fail to represent anything in the first place. What accounts for the phenomenal character of visual experiences is not the content itself, but rather the vehicle of content, that is, not the properties represented by visual experience, but rather the relational properties of experience (...) of representing singular contents, namely particular instantiations of properties. I argue that the Russellian particular-involving proposition is the only appropriate model for the representational content of visual experience and hence that visual hallucinations are just like failed demonstrations. (shrink)

My aim is to defend a peculiar epistemic version of the particularity thesis, which results from a sui generis combination of what I call the ‘singular relational view’ and what I call the ‘relativistic content view.’ Particulars are not represented as part of putative singular content. Instead, we are perceptually acquainted with them in the relevant sense that experience puts us in direct perceptual contact with them. And the content of experience is best modeled as a propositional function, that is, (...) the content of a complex predicate that is true or false only relative to some circumstances of evaluation. (shrink)

The idea that what we perceive are tropes is anything but new. In fact, it was one of the reasons why the ontology of tropes was postulated in the first place. Still, the claim that we perceive tropes is invariably and purely based on pre-philosophical intuitions or, indirectly, either as a supporting argument for the advantages of content view when compared to the relational view of experience, or as a supporting argument in favor of the irreducible subjective character of experience. (...) In this paper, I take the content view for granted and argue in favor of what is herein referred to as the trope-content view of experience. My defense is a case of inference to the best explanation. The trope-content view can meet all reasonable desiderata on the experience and its content without assuming gaps or making the ad hoc assumption that there are different layers of content, or so shall I argue.

Phenomenal intentionality is a singular form of intentionality. Science shows it is internally-determined. So standard externalist models for reducing intentionality don't apply to it.

H. H. Price (1932) held that experience is essentially presentational. According to Price, when one has an experience of a tomato, nothing can be more certain than that there is something of which one is aware. Price claimed that the same applies to hallucination. In general, whenever one has a visual experience, there is something of which one is aware, according to Price. Call this thesis Item-Awareness.

Physicalism about colour is the thesis that colours are identical with response-independent, physical properties of objects. I endorse the Argument from Structure against Physicalism about colour. The argument states that Physicalism cannot accommodate certain obvious facts about colour structure: for instance, that red is a unitary colour while purple is a binary colour, and that blue resembles purple more than green. I provide a detailed formulation of the argument. According to the most popular response to the argument, the Physicalist can (...) accommodate colour structure by explaining it in terms of colour experience. I argue that this response fails. Along the way, I examine other interesting issues in the philosophy of colour and colour perception, for instance the relational structure of colour experience and the description theory of how colour names refer.

Develops an empirical argument against naive realism-disjunctivism: if naive realists accept "internal dependence", then they cannot explain the evolution of perceptual success. Also presents a puzzle about our knowledge of universals.

The claim that perfect hallucination is introspectively indistinguishable from perception has been a centrepiece of philosophical theorizing about sense experience. The most common interpretation of the indistinguishability claim is modal: that it is impossible to distinguish perfect hallucination from perception through introspection alone. I run through various models of introspection and show that none of them can accommodate the modal interpretation. Rejecting the modal interpretation opens up two alternative interpretations of the indistinguishability claim. According to the generic interpretation, hallucination is (...) indistinguishable from perception despite the existence of possible exceptions, while according to the actuality interpretation, the indistinguishability of hallucination from perception consists in the actual failure to distinguish hallucination from perception. These alternative understandings of the indistinguishability claim have a number of significant implications for the problem of perception, including the rejection of perfect hallucination and illusion in favour of our ordinary, non-philosophical concepts of these states. (shrink)

The long history of theorizing about perception divides into two quite distinct and irreconcilable camps, one that takes sensory experience to show us external reality just as it is, and one that takes such experience to reveal our own mind. I argue that we should reject both sides of this debate, and admit that the phenomenal character of experience, as such, reveals little about the nature of the external world and even less about the mind.

This paper argues that McDowell is right to claim that disjunctivism has anti-sceptical implications. While the disjunctive conception of experience leaves unaffected the Cartesian sceptical challenge, it undermines another type of sceptical challenge. Moreover, the sceptical challenge against which disjunctivism militates has some philosophical urgency in that it threatens the very notion that perceptual experience can acquaint us with the world around us.

Suppose that you are looking at a vase of flowers on the table in front of you. You can visually attend to the vase and to the flowers, noticing their different features: their colour, their shape and the way they are arranged. In attending to the vase, the flowers and their features, you are attending to mind-independent objects and features. Suppose, now, that you introspectively reflect on the visual experience you have when looking at the vase of flowers. In doing (...) so, you might notice various features of your experience, for example that individual petals on the flowers are difficult to distinguish. Although in introspection your interest is in the character of your experience, your attention is still to the objects of your experience – to the mind-independent vase and the flowers. Since attending to your experience involves attending to the mind-independent objects and features of your experience, your experience seems introspectively to involve those mind-independent objects and features. 2In general, then, when we introspect a visual experiential episode, it seems that we are related to some mind-independent object or feature that is present and is a part, or a constituent, of the experience. We can call this property – the property of having some mind-independent object or feature as a constituent – the naïve realist property of experiences. It is widely accepted that visual experiences seem to have the NR property; 3 naïve realism is the view that some experiences – the veridical ones – actually do have it: " veridical experiential episodes have mind-independent objects and features as constituents."On a plausible conception of phenomenal character, the phenomenal character of a perceptual experience just is those properties of the experience that explain the way it introspectively seems. Naïve realism is then the view that veridical …. (shrink)

In defence of naïve realism, Fish has advocated an eliminativist view of hallucination, according to which hallucinations lack visual phenomenology. Logue, and Dokic and Martin, respectively, have developed the eliminativist view in different manners. Logue claims that hallucination is a non-phenomenal, perceptual representational state. Dokic and Martin maintain that hallucinations consist in the confusion of monitoring mechanisms, which generates an affective feeling in the hallucinating subject. This paper aims to critically examine these views of hallucination. By doing so, I shall (...) point out what theoretical requirements are imposed on naïve realists who characterize hallucinations as non-visual-sensory phenomena. (shrink)

Some have claimed that there are laws of appearance, i.e. in principle constraints on which types of sensory experiences are possible. Within a representationalist framework, these laws amount to restrictions on what a given experience can represent. I offer an in-depth defence of one such law and explain why prevalent externalist varieties of representationalism have trouble accommodating it. In light of this, I propose a variety of representationalism on which the spatial content of experience is determined by intrinsic features of (...) conscious subjects. I conclude by considering an externalist-friendly reworking of my proposal, but suggest that the success of such a reworking is dubious. (shrink)

I use an old challenge to motivate a new view. The old challenge is due to variation in our perceptions of secondary qualities. The challenge is to say whose perceptions are accurate. The new view is about how we manage to perceive secondary qualities, and thus manage to perceive them accurately or inaccurately. I call it perceptual structuralism. I first introduce the challenge and point out drawbacks with traditional responses. I spend the rest of the paper motivating and defending a (...) structuralist response. While I focus on color, both the challenge and the view generalize to the other secondary qualities. (shrink)

This paper sets out a novel response to the ‘screening off problem’ for naïve realism. The aim is to resist the claim (which many naïve realists accept) that the kind of experience involved in hallucinating also occurs during perception, by arguing that there are causal constraints that must be met if an hallucinatory experience is to occur that are never met in perceptual cases. Notably, given this response, it turns out that, contra current orthodoxy, naïve realists need not adopt any (...) particular view about the psychological nature of hallucinatory experience to handle the screening off problem. Consequently, room opens up for naïve realists to endorse whatever theory of hallucinatory experience seems to best capture the distinctive nature of such episodes. (shrink)

Relationalists about episodic memory must endorse a disjunctivist theory of memory-experience according to which cases of genuine memory and cases of total confabulation involve distinct kinds of mental event with different natures. This paper is concerned with a pair of arguments against this view, which are analogues of the ‘causal argument’ and the ‘screening off argument’ that have been pressed in recent literature against relationalist (and hence disjunctivist) theories of perception. The central claim to be advanced is that to deal (...) with these two arguments, memory disjunctivists both can and should draw on resources that are standardly appealed to by rival common factor theories of episodic memory, and, in particular, to the idea that genuine memories and merely apparent ones are to be distinguished, at least in part, in terms of the distinctive ways in which they are caused. On the proposed view, there are substantive causal constraints associated both with cases of genuine memory and with cases of mere confabulation. The resulting theory thus tells us something important about the nature both of genuine memories and of mere confabulations, namely, that such experiences must be caused in certain distinctive ways and cannot occur except as the result of a distinctive sort of causal process. In addition, the theory enables the disjunctivist to offer a unified response to an important pair of arguments against her view. (shrink)

Disjunctivists maintain that perceptual experiences and hallucinatory experiences are distinct kinds of event with different metaphysical natures. Moreover, given their view about the nature of perceptual cases, disjunctivists must deny that the perceptual kind of experience can occur during hallucination. However, it is widely held that disjunctivists must grant the converse claim, to the effect that the hallucinatory kind of experience occurs even during perception. This paper challenges that thought. As we will see, the argument for thinking that the hallucinatory (...) kind of experience is present even in cases of perception depends on prior acceptance of a ‘non-demanding’ conception of hallucination, on which all it takes to produce an hallucinatory experience is to induce in the subject the right kind of neurological condition. On the view developed here, by contrast, there are substantive causal conditions, going beyond the mere occurrence of the right kind of neurological state, that must be met if an experience of the hallucinatory kind is to occur. By drawing on this view, I argue, disjunctivists can deny that the kind of experience involved in hallucination ever occurs during perception. This then allows disjunctivists to avoid certain important problems they would otherwise face. It also leaves them with considerably more freedom when it comes to theorising about the nature of hallucinatory experience. (shrink)

Those arguing for the existence of non-propositional content appeal to emotions for support, although there has been little engagement in those debates with developments in contemporary theory of emotion, specifically in connection with the kind of mental states that emotional experiences are. Relatedly, within emotion theory, one finds claims that emotional experiences per se have non-propositional content without detailed argument. This paper argues that the content of emotional experience is propositional in a weak sense, associated with aspectual experience and correctness (...) conditions. Furthermore, it provides an interpretation of purely-objectual emotional experiences which satisfies this weak view of propositional content. (shrink)

There is a traditional conception of sensory experience on which the experiences one has looking at, say, a cat could be had by someone merely hallucinating a cat. Disjunctivists take issue with this conception on the grounds that it does not enable us to understand how perceptual knowledge is possible. In particular, they think, it does not explain how it can be that experiences gained in perception enable us to be in ‘cognitive contact’ with objects and facts. I develop this (...) chal- lenge to the traditional conception and then show that it is possible to accommo- date an adequate account of cognitive contact in keeping with the traditional conception. One upshot of the discussion is that experiences do not bear the explanatory burden placed upon them by disjunctivists. (shrink)

A perceptual experience of a given object seems to make the object itself present to the perceiver’s mind. Many philosophers have claimed that naïve realism (the view that to perceive is to stand in a primitive relation of acquaintance to the world) provides a better account of this phenomenological directness of perceptual experience than does the content view (the view that to perceive is to represent the world to be a certain way). But the naïve realist account of this phenomenology (...) has a conspicuous shortcoming: it explains the phenomenological directness of veridical perceptual experiences but not of hallucinations. Conversely, I maintain that a particular variety of the content view provides a unified account of the phenomenological directness of both veridical and hallucinatory experiences. If so, then contrary to what is often assumed, the phenomenological facts concerning perceptual experience are explained better by the content view than by naïve realism, and consequently, we have a compelling reason to prefer the content view to naïve realism.

When you have a perceptual experience of a given physical object that object seems to be immediately present to you in a way it never does when you consciously think about or imagine it. Many philosophers have claimed that naïve realism (the view that to perceive is to stand in a primitive relation of acquaintance to the world) can provide a satisfying account of this phenomenological directness of perceptual experience while the content view (the view that to perceive is to (...) represent the world to be a certain way) cannot. I argue that this claim is false. Specifically, I maintain that the only acceptable naïve realist account of the relevant phenomenology is circular and that the content view can provide a similar account. In addition, I maintain that a certain specific variety of the content view provides a non-circular and thus more satisfactory account of this phenomenology. If so, then contrary to what is commonly assumed there are powerful phenomenological grounds for preferring the content view to naïve realism. (shrink)

The fact that you see some particular object seems to be due to the causal relation between your visual experience and that object, rather than to your experiences’ phenomenal character. On the one hand, whenever some phenomenal element of your experience stands in the right sort of causal relation to some object, your experience presents that object (your experience’s phenomenology doesn’t need to match that object). On the other hand, you can’t have a perceptual experience that presents some object unless (...) you stand in the right sort of causal relation to that object (no matter how closely your experience’s phenomenology matches some object). According to the continuity thesis, property perception is similar to object perception in these two respects. A standard reason to reject the continuity thesis is the assumption that the environmental properties that a perceptual experience presents are determined by its phenomenal properties (which are not determined by the environmental properties that cause the experience). I maintain that the continuity thesis is false but for a different reason: perceptual experiences present both objects and properties via manners of presentation; but, whereas perceptual manners of presentation for objects are purely relational, perceptual manners of presentation for properties are satisfactional. (shrink)

Recently, a number of philosophers have argued that property illusions—cases in which we perceive a property, but that property is not the property it seems to us to be in virtue of our perceptual experience—and veridical illusions—cases in which we veridically perceive an object’s properties, but our experience of some specific property is nonetheless unsuccessful or illusory—can occur. I defend the contrary view. First, I maintain that there are compelling reasons to conclude that property illusions and veridical illusions can’t occur; (...) and second, I maintain that the considerations supporting the possibility of such cases are uncompelling.

This articles develops a taxonomy of memory errors in terms of three conditions: the accuracy of the memory representation, the reliability of the memory process, and the internality (with respect to the remembering subject) of that process. Unlike previous taxonomies, which appeal to retention of information rather than reliability or internality, this taxonomy can accommodate not only misremembering (e.g., the DRM effect), falsidical confabulation, and veridical relearning but also veridical confabulation and falsidical relearning. Moreover, because it does not assume that (...) successful remembering presupposes retention of information, the taxonomy is compatible with recent simulation theories of remembering. (shrink)

Naïve realism is a theory of perception with great explanatory ambitions. It has been influentially argued that, in order to realize these explanatory ambitions, the naïve realist should say that any perception belongs to just one fundamental kind. I think, however, that adopting this commitment does not particularly help the naïve realist to realize her explanatory ambitions, and so is not warranted. This result is significant because once this commitment about fundamental kinds is relinquished, we see that it is possible (...) to develop some new and surprising forms of naïve realism—most notably, what I call pluralist naïve realism.

Much of the plausibility of epistemic conservatism derives from its prospects of explaining our rationality in holding memory beliefs. In the first two parts of this paper, I argue for the inadequacy of the two standard approaches to the epistemology of memory beliefs, preservationism and evidentialism. In the third, I point out the advantages of the conservative approach and consider how well conservatism survives three of the strongest objections against it. Conservatism does survive, I claim, but only if qualified in (...) certain ways. Appropriately qualified, conservatism is no longer the powerful anti-skeptical tool some have hoped for, but a doctrine closely connected with memory. (shrink)

I propose an account of desire that reconciles two apparently conflicting intuitions about practical agency. I do so by exploring a certain intuitive datum. The intuitive datum is that often when an agent desires P she will seem to immediately and conclusively know that there is a reason to bring P about. Desire-based theories of reasons seem uniquely placed to explain this intuitive datum. On this view, desires are the source of an agent’s practical reasons. A desire for P grounds (...) conclusive knowledge of a reason to bring P about because that desire makes it true that there is a reason to do so. However, this implies that a basic desire for P can never be in error about there being at least some reason to bring P about. We have the conflicting intuition that basic desires sometimes rationally count for nothing. The guise of the good explains this intuition about the fallibility of desires. On this view, a desire for P represents P as good in some respect. Desires and reasons are independent, so a desire might misrepresent one’s reasons. But this independence is usually taken to rule out that desires ever provide conclusive knowledge of reasons. Capturing the intuition about conclusive knowledge rules out capturing the intuition about fallibility, and vice versa. I propose an epistemological disjunctivist version of the guise of the good that reconciles fallibility with the possibility of conclusive knowledge. (shrink)

According to the guise of the good, a desire for P represents P as good in some respect. ‘Perceptualism’ further claims that desires involve an awareness of value analogous to perception. Perceptualism explains why desires justify actions and how desires can end the regress of practical justification. However, perception paradigmatically represents the actual environment, while desires paradigmatically represent prospective states. An experience E is an awareness of O when the nature of E depends on the nature of O. How could (...) desires depend on the merely possible? Extant perceptualist accounts have not adequately addressed this question. I propose a novel account of how desires can be an awareness of value. An awareness of value involves the successful exercise of a capacity to discriminate value out of non-evaluative representations. The resulting content and phenomenology of such a desire depends in the right way on the value properties of the desired state. An agent requires the right view of the non-evaluative features of a state to discriminate its evaluative features. I argue that imaginings are uniquely able to provide such a view, and so enable value discriminations. My account retains the epistemological attractions of perceptualism despite the disanalogy between desire and perception. (shrink)

According to the virtual self theory, selves are merely virtual entities. On this view, our self-representations do not refer to any concrete object and the self is a merely intentional entity. This contemporary version of the ‘no-self’ theory is driven by a number of psychological and philosophical considerations indicating that our representations of the self are pervasively inaccurate. I present two problems for VST. First, the case for VST fails to rule out a more moderate position according to which the (...) self exists but is systematically misrepresented by us. This position regards the self as a real entity that has illusory appearances, rather than as a hallucinated entity that has a merely intentional existence. Second, I suggest that this ‘illusion model’ of self-misrepresentation is preferable to VST. Advocates of VST must acknowledge the existence of an entity—typically the brain—that is the bearer of our misrepresentations of the self. I argue that, other things being equal, we should regard the bearer of our self-representations as the self, even if that entity diverges dramatically from the way we represent the self to be. So by acknowledging the existence of a bearer of self-representations, advocates of VST are in a poor position to deny the existence of the self. I conclude that VST not only fails to rule out the illusion model, but that we have prima facie reason to prefer the illusion model to VST. (shrink)

Some recently popular accounts of perception account for the phenomenal character of perceptual experience in terms of the qualities of objects. My concern in this paper is with naturalistic versions of such a phenomenal externalist view. Focusing on visual spatial perception, I argue that naturalistic phenomenal externalism conflicts with a number of scientific facts about the geometrical characteristics of visual spatial experience.
