La pornographie serait-elle l’objet d’un malentendu? Alors qu’elle s’offre une santé particulièrement réjouissante au regard du commerce mondial, il semblerait que les jugements portés sur elle ne parviennent jamais à toucher leur but. C’est que la pornographie brouille cette aptitude à dessiner clairement les limites que l’on souhaiterait repérer entre réel et imaginaire. La condamnation de cette imagerie sous l’étiquette « obscène » révèle ainsi l’incapacité à juger de la place véritable des représentations de la sexualité dans notre société, mais (...) aussi et surtout, elle révèle la difficulté à identifier le réel lui-même, et signe un dialogue de sourds sur le sens que l’on pourrait donner aux choses représentées en général. C’est sans doute qu’il y a méprise sur l’objet même de la représentation. C’est aussi que l’analyse qui ressort de ce phénomène ne parvient que rarement à sortir d’un aveuglement subtilement construit par les appartenances culturelles et les intérêts idéologiques. Effaçant les frontières a priori certaines entre imaginaire et réel, l’image pornographique donnerait au jugement une portée incapable de s’ancrer dans l’un où l’autre monde. (shrink)

Some experiments in perceptual psychology measure perceivers’ phenomenal experiences of objects versus their cognitive assessments of object properties. Analyzing such experiments, this article responds to Pizlo’s claim that much work on shape constancy before 1985 confused problems of shape ambiguity with problems of shape constancy. Pizlo fails to grasp the logic of experimental designs directed toward phenomenal aspects of shape constancy. In the domain of size perception, Granrud’s studies of size constancy in children and (...) adults distinguish phenomenal from cognitive factors. (shrink)

Naive observers viewed a sequence of colored Mondrian patterns, simulated on a color monitor. Each pattern was presented twice in succession, first under one daylight illuminant with a correlated color temperature of either 16,000 or 4,000 K and then under the other, to test for color constancy. The observers compared the central square of the pattern across illuminants, either rating it for sameness of material appearance or sameness of hue and saturation or judging an objective property—that is, whether its (...) change of color originated from a change in material or only from a change in illumination. Average color constancy indices were high for material appearance ratings and binary judgments of origin and low for hue–saturation ratings. Individuals’ performance varied, but judgments of material and of hue and saturation remained demarcated. Observers seem able to separate phenomenal percepts from their ontological projections of mental appearance onto physical phenomena; thus, even when a chromatic change alters perceived hue and saturation, observers can reliably infer the cause, the constancy of the underlying surface spectral reflectance.

This chapter provides an overview of the phenomenology of size perception and the use of instructions to tease apart phenomenal and cognitive aspects. It develops his own recent proposals concerning the geometry of visual space. The chapter proposes that visual space is contracted along the lines of sight. This contraction would explain the apparent convergence of railway tracks, but without invoking a “proximal mode” experience. Parallel railway tracks receding into the distance project converging lines onto the retinas. A true (...) proximal mode representation would show these lines converging as if in a vertical plane. But we experience them as converging while also receding in depth along the ground. The chapter suggests that this calls for a third geometry of visual space, intermediate between a linear perspective projection and full phenomenal constancy. The chapter attributes reports of full constancy to cognitive factors. size perception, visual space, geometry, lines of sight, proximal mode, phenomenal constancy. (shrink)

This article proposes an account of color constancy based on an examination of the relevant scientific literature. Differences in experimental settings and task instructions that lead to variation in subject performance are given particular attention. Based on the evidence discussed, the core of the proposal made is that there are two different forms of color constancy, one phenomenal and the other projective. This follows the hypothesis of Reeves et al. (Perception & Psychophysics 70:219–228, 2008). Unlike Reeves et (...) al. (Perception & Psychophysics 70:219–228, 2008), it is argued that projective color constancy is crucially dependent upon phenomenal color constancy and certain aspects of scene perception. Additionally, it is hypothesized that capacities that support projective color constancy have an important role to play in facilitating our ability to quickly recognize scenes with diagnostic chromatic properties independently of assignments of colors to object surfaces.

Representationalism, the view that phenomenal character supervenes on intentional content, has attracted a wide following in recent years. Most representationalists have also endorsed what I call 'standard Russellianism'. According to standard Russellianism, phenomenal content is Russellian in nature, and the properties represented by perceptual experiences are mind-independent physical properties. I argue that standard Russellianism conflicts with the everyday experience of colour constancy. Due to colour constancy, standard Russellianism is unable to simultaneously give a proper account of (...) the phenomenal content of colour experience and do justice to its phenomenology. (shrink)

This chapter reconsiders the notion of perceptual constancy from the ground up. It distinguishes the phenomenology of perceptual constancy and stability from a functional characterization of perception as aiming at full constancy. Drawing on this distinction, we can attend to the phenomenology of constancy itself, and ask to what extent human perceivers attain constancy, as usually defined. Within this phenomenology, I distinguish phenomenal presentations of spatial features and color properties from categorizations, conceptualizations, and judgments (...) that underlie verbal or other responses to those presentations. Although phenomenal presentation and categorization commonly co-occur, they are distinct aspects of experience. After reviewing several standard descriptions of constancy, I present laboratory findings and my own phenomenological descriptions by way of confirming that, although perception "tends toward" constancy, human perceivers do not usually attain full constancy for either spatial or chromatic properties (as many investigators acknowledge). For spatial perception, I find that the phenomenology has been systematically misdescribed, and I offer a more adequate description of the phenomenology of everyday spatial perception. However, my greatest quarrel with previous theory concerns the functional aim of the constancies. I argue not only that perception does not achieve full constancy but that we should not characterize it as aiming for full constancy. Rather, perception seeks a stability of representation suitable for guiding our actions and which can also, as needed, enable us to classify and re-identify objects by phenomenally presented properties such as shape, size, or color. Further, I argue that theorists should not confuse these classifications with the qualitative character of phenomenal experience. My arguments underscore the need to distinguish phenomenal representation (better, "presentation") from conceptual categorization, and to distinguish perceptual presentations from subsequent processes that are involved in responding to them.

All representationalists maintain that there is a necessary connection between an experience’s phenomenal character and intentional content; but there is a disagreement amongst representationalists regarding the nature of those intentional contents that are necessarily connected to phenomenal character. Russellian representationalists maintain that the relevant contents are composed of objects and/or properties, while Fregean representationalists maintain that the relevant contents are composed of modes of presentation of objects and properties. According to Fregean representationalists such as David Chalmers and Brad (...) Thompson, the Fregean variety of the view is preferable to the Russellian variety because the former can accommodate purported counterexamples involving spectrum inversion without illusion and colour constancy while the latter cannot. I maintain that colour constancy poses a special problem for the Fregean theory in that the features of the theory that enable it handle spectrum inversion without illusion cannot be extended to handle colour constancy. I consider the two most plausible proposals regarding how the Fregean view might be developed in order to handle colour constancy—one of which has recently been defended by Thompson —and argue that neither is adequate. I conclude that Fregean representationalism is no more able to accommodate colour constancy than is Russellian representationalism and, as such, ought to be rejected. (shrink)

This article explains and defends the existence of value constancy, understood on the model of color constancy. Color constancy involves a phenomenal distinction between the transient color appearances of objects and the unchanging colors that those objects appear to have. The existence of value constancy allows advocates of response-dependent accounts of value to reject the question “What is the uniquely appropriate attitude to have toward this evaluative property?” as containing a false uniqueness assumption. Rejecting this (...) assumption allows response-dependent accounts of value to deflect or answer a host of popular objections. (shrink)

When you look at a circular plate at an angle, it looks circular. But there also is a certain sense in which its look can be described as oval. When you move, the plate’s look changes with your perspective on it—nevertheless, it continues to look circular. This chapter investigates whether these “constancy in variation” phenomena can be explained in terms of the representational content of visual experience, and whether constancy in variation provides special, phenomenological, reasons to construe experience (...) as having centered contents. Concentrating on shape, it argues that due to warring phenomenological demands, all views construing constancy in variation as representation of both objective and perspectival properties or features have limited explanatory powers, and that centering does not provide any advantage. By contrast, adopting the non-standard intentionalism called phenomenal intentionalism, we get rather natural explanations of the phenomenology of constancy in variation. (shrink)

Perceptual experience has the phenomenal character of encountering a mind-independent objective world. What we encounter in perceptual experience is not presented to us as a state of our own mind. Rather, we seem to encounter facts, objects, and properties that are independent from our mind. In short, perceptual experience has phenomenal objectivity. This paper proposes and defends a Kantian account of phenomenal objectivity that grounds it in experiences of lawlike regularities. The paper offers a novel account of (...) the connection between phenomenology and intentionality. It also sheds some light on one of the central themes in Kant’s Critique of Pure Reason. (shrink)

This chapter considers the ways in which whiteness as a skin color and ideology becomes a dominant level that sets the background against which all things, people and relations appear. Drawing on Merleau-Ponty's phenomenology, it takes up a series of films by Bruce Nauman and Marlon Riggs to consider ways in which this level is phenomenally challenged providing insights into the embodiment of racialization.

In this paper, I defend a representationalist account of the phenomenal character of color experiences. Representationalism, the thesis that phenomenal character supervenes on a certain kind of representational content, so-called phenomenal content, has been developed primarily in two different ways, as Russellian and Fregean representationalism. While the proponents of Russellian and Fregean representationalism differ with respect to what they take the contents of color experiences to be, they typically agree that colors are exhaustively characterized by the three (...) dimensions of the color solid: hue, saturation, and lightness. I argue that a viable version of representationalism needs to renounce this restriction to three dimensions and consider illumination to be a genuine phenomenal dimension of color. My argument for this thesis falls into two parts. I first consider the phenomenon of color constancy in order to show that neither Russellian nor Fregean representationalism can do justice to the phenomenal significance of local illumination. I subsequently formulate a version of representationalism that accounts for illumination by taking it as a phenomenal dimension of color. (shrink)

Seeing happens effortlessly and yet is endlessly complex. Among the most fascinating aspects of visual perception is its stability and constancy. As we shift our gaze or move about the world, the light projected onto the retinas is constantly changing. Yet the surrounding objects appear stable in their properties. Psychologists have long been interested in the constancies. They have asked questions such as: How good is constancy? Is constancy a fact about how things look, or is it (...) a product of our beliefs and judgments about how things look? How can the contents of visual experience be studied experimentally? Philosophers have long been interested in characterizing visual experience and have become widely interested in the constancies more recently. As psychologists and philosophers have interacted, new questions have arisen: If experience is not as of retinal stimulation (proximal mode), but does not always exhibit constancy (or at least not in all respects), how shall we describe this intermediate state? Also, should we regard any departure from constancy as a failure of the visual system, or might it be a reasonable or adaptive response? In what circumstances is seeing highly conditioned by cognitive factors such as background assumptions, and in what circumstances not? Our volume focuses on size constancy and color constancy. It considers methodologies for studying conscious visual perception, efforts to describe visual experience in relation to constancy, what it means that constancy is not always perfect, and the conceptual resources needed for explaining visual experience.

Sydney Shoemaker has gone to great lengths to defend a repre-sentationalist view of phenomenal character, and yet he describes this view as breaking with standard representationalism in two ways. First, he thinks his representationalist position is consis- tent with the possibility of spectrum inversion, and second, he thinks there are qualia. Thus, we can think of his position in the qualia debate as moderate representationalism (or, equally, moderate qualia realism) by taking up some middle ground be- tween these two (...) major camps. This \moderate" view faces several problems. Here I will very briey explain Shoemaker's represen- tationalist account of spectrum inversion in which he appeals to the existence of a certain sort of subjective property of objects, namely, what he calls appearance properties (formerly he called these phenomenal properties). I will argue that an alternative ver- sion of representationalism provides a more plausible explanation of both inversion-type scenarios and Shoemaker's color constancy case, which he uses to motivate the existence of these subjective properties, without positing appearance properties at all.

This paper develops an appearance view of perception (focusing on vision). When we see an object, we see it by having it appear some way to us. We see the object, not the appearance; but we see the object via the appearance. The appearance is subjectively conditioned: aspects of it depend on attributes of the subject. We mentally have the appearance and can reflect on it as an appearance. But in the primary instance, of veridical perception, it is the object (...) that we focus on and experience. I contrast this view with naive realism (sometimes called disjunctivism) (Brewer, Campbell, Noe) and with intentionalist or representationalist views, which I call the physical content view (Dretske, Tye, Crane, Hill, Burge). I agree with these views in rejecting sense-data intermediaries and in affirming direct perception, but I argue that direct perception occurs via appearances, making mine a critical direct realism. The other views attempt to explain the spatial content of perception (shape, size, distance) entirely through the physical properties of objects and their physical relation to the perceiver (viewing position). I argue instead that there are ineliminably subjective aspects of normal spatial perception, which are systematically manifested as a lack of full phenomenal constancy. This systematic underconstancy can’t be accounted for at all by a consistent naive realism; for the physical content view, it requires that most of our ordinary perception is classified as illusory, violating the spirit of that view. Accepting phenomenal underconstancy as pervasive, I suggest that our ability to perceive the mind-independent properties of objects depends on developed conceptual abilities. In the final section, I compare my appearance view with the adverbialism of Chisholm and the critical direct realism of Roy Wood Sellars. (shrink)

Do the physical facts of the viewed environment account for the ordinary experiences we have of that environment? According to standard philosophical views, distal facts do account for our experiences, a phenomenon explained by appeal to perceptual constancy, the phenomenal stability of objects and environmental properties notwithstanding physical changes in proximal stimulation. This essay reviews a significant but neglected research tradition in experimental psychology according to which percepts systematically do not correspond to mind-independent distal facts. Instead, stability of (...) percept values comes in degrees, and physical facts about the viewed environment alone do not account for our ordinary experiences of the world. I conclude that more attention to descriptive research in psychophysics is warranted if what is sought is a philosophical theory of the nature of our perceptual relation with the world. (shrink)

The term “perceptual constancy” was used by the Gestalt theorists in the early part of the twentieth century (e.g., Koffka 1935, 34, 90) to refer to the tendency of perception to remain invariant over changes of viewing distance, viewing angle, and conditions of illumination. This tendency toward constancy is remarkable: every change in the viewing distance, position, and illumination is necessarily accompanied by a change in the local proximal (retinal) stimulation, and yet perception remains relatively stable. The tendency (...) toward perceptual constancy encouraged the Gestalt theorists to look beyond local proximal stimulation in grounding their theories of perception. In the ensuing decades, much has been learned about the constancies. Evidence for this assertion may be found in the contributions to the current volume as well as in earlier volumes (e.g., Epstein 1977; Walsh and Kulikowsky 1998). These advances notwithstanding, significant questions remain open. Our aim here is to note some advances and specify some open questions. (shrink)

Visual space can be distinguished from physical space. The first is found in visual experience, while the second is defined independently of perception. Theorists have wondered about the relation between the two. Some investigators have concluded that visual space is non-Euclidean, and that it does not have a single metric structure. Here it is argued that visual space exhibits contraction in all three dimensions with increasing distance from the observer, that experienced features of this contraction are not the same as (...) would be the experience of a perspective projection onto a fronto-parallel plane, and that such contraction is consistent with size constancy. These properties of visual space are different from those that would be predicted if spatial perception resulted from the successful solution of the inverse problem. They are consistent with the notion that optical constraints have been internalized. More generally, they are also consistent with the notion that visual spatial structures bear a resemblance relation to physical spatial structures. This notion supports a type of representational relation that is distinct from mere causal correspondence. The reticence of some philosophers and psychologists to discuss the structure of phenomenal space is diagnosed in terms of the simple materialism and the functionalism of the 1970s and 1980s.

Are colors relational or non-relational properties of their bearers? Is red a property that is instantiated by all and only the objects with a certain intrinsic (/non-relational) nature? Or does an object with a particular intrinsic (/non-relational) nature count as red only in virtue of standing in certain relations - for example, only when it looks a certain way to a certain perceiver, or only in certain circumstances of observation? In this paper I shall argue for the view that color (...) properties are relational (henceforth, relationalism), and against the view that colors are not relational (henceforth, anti- or non-relationalism).

According to contemporary representationalism, phenomenal qualia—of specifically sensory experiences—supervene on representational content. Most arguments for representationalism share a common, phenomenological premise: the so-called “transparency thesis.” According to the transparency thesis, it is difficult—if not impossible—to distinguish the quality or character of experiencing an object from the perceived properties of that object. In this paper, I show that Husserl would react negatively to the transparency thesis; and, consequently, that Husserl would be opposed to at least two versions of contemporary representationalism. (...) First, I show that Husserl would be opposed to strong representationalism, since he believes the cognitive content of a perceptual episode can vary despite constancy of sensory qualia. Second, I then show that Husserl would be opposed to weak representationalism, since he believes that sensory qualia—specifically, the sort that he calls “kinesthetic sensations”—can vary despite constancy in representational content.

I defend a solution to a long-standing problem with perceptual appearances, brought about by the phenomenon of perceptual constancy. The problem is that in conditions which are non-ideal, yet within the range that perceptual constancy works, we see things veridically despite an “appearance” which is traditionally taken to be non-veridical. For example, a tilted coin is often taken to have an “elliptical appearance”, shadowed surfaces a “darker appearance”. These appearances are puzzling for a number of reasons. I defend (...) and elaborate on an approach taken by Sean Kelly, and earlier by the art historian E.H. Gombrich, according to which we can be tricked by our ability to bring about a kind of Gesltalt shift between different possible perceptual interpretations of a scene. (shrink)

I defend the thesis that most or all perceptual experiences are infused with imaginative contributions. While the idea is not new, it has few supporters. I begin by developing a framework for the underlying debate. Central to that framework is the claim that a perceptual experience is infused with imagination if and only if there are self-generated contributions to that experience that have ampliative effect on its phenomenal and directed elements. Self-generated ingredients to experience are produced by the subject (...) as opposed to being received from the world. Some form of stored content is an obvious starting point. Ampliative effects are aspects of perceptual experience that outstrip the content the senses get from the world. This conceptual framework is applied to three case studies: object-sameness and object-kind recognition (section 2), memory colour (section 3), and perceptual constancy and amodal completion (section 4). If the three cases and my overall analysis are accepted (a substantive if), then we have a forceful inductive argument for perception being infused with imagination. (shrink)

This chapter discusses the following: (i) The Kantian concept of the Transcendental Object, and of its relation to that of the Noumenon and the Thing-in-itself; (ii) Kant's theory of knowledge cannot be positivistically interpreted, but requires underlying unities that hold appearances together, and which, by their identity, give the latter constancy of character; (iii) Kant's theory of knowledge cannot be idealistically interpreted, since it accepts the reality of a Transcendental Subject and of transcendental acts that exist beyond experience and (...) knowledge, and are constitutive of it. It also accepts the reality of many Transcendental Objects that affect our subjectivity and which have characters and relations not given to the latter, at best corresponding to phenomenal characters and relations; (iv) Kant's phenomenalism is more radical than other phenomenalisms in that it accepts space and time only as ordering forms for phenomena. But it advances important arguments, based mainly on ontological criteria, for restricting them to what is thus phenomenal; (v) The regular connection among the appearances of objects is the necessary empirical surrogate for the unity of the objects from which they spring. Kant therefore makes use of his metempirical presuppositions to illuminate phenomenal data. (shrink)

Here I reexamine Duhem's question of the continuity between medieval dynamics and early modern conservation theories. I concentrate on the heavens. For Aristotle, the motions of the heavens are eternally constant (and thus mathematizable) because an eternally constant divine Reason is their mover. Duhem thought that impetus and conservation theories, by extending sublunar mechanics to the heavens, made a divine renewer of motion redundant. By contrast, I show how Descartes derives his law of conservation by extending Aristotelian celestial dynamics to (...) the earth. Descartes argues that motion is intrinsically linear, not circular. But he agrees that motion is mathematically intelligible only where divine Reason moves bodies in a constant and eternal motion. Descartes strips bodies of active powers, leaving God as the only natural mover; thus both celestial and sublunar motions are constant, and uniformly mathematizable. The law of conservation of the total quantity of motion is an attempt to harmonize the constancy derived a priori with the phenomenal inconstancy of sublunar motions. (shrink)

In this thesis, I both analyze the phenomenology of vision from a geometrical point of view, and also develop certain connections between that geometrical analysis and the mind body problem. In order to motivate the need for such an analysis, I first show, by means of a refutation of direct realism, that visual space is never identical with any of the physical objects being indirectly "seen" by constituting color arrangements in it. It thus follows that the geometry of visual space (...) may be quite different from the Euclidean geometry of physical space, and I proceed to analyze that geometry. ;I argue that topologically, visual space is two dimensional, inasmuch as regions of it are capable of being bounded by a line, such as the borders around the various objects constituted in it. An apparent paradox arises here though, inasmuch as we posess phenomenal depth perception, which is particularly striking during binocular vision, and thus the question arises as to how the binocular depth cue of retinal disparity is registered phenomenally in a two dimensional space. I resolve this apparent paradox by arguing that the internal metric struture of this space can be apprehended phenomenally, and can serve as such a phenomenal depth cue. It is shown that holistically, this metric structure is elliptical, since for example marginal distortions in wide-angle photography are not present in visual space, and it is also noted that there is a tendency towards size constancy in visual perception. It is shown from these geometrical considerations that visual space posseses a variable curvature, with that curvature being determined by the physical depths of objects constituted in the space. ;Finally, I investigate what bearing the preceding geometrical conclusions have on the question of how events in visual space may be causally determined by neural events in the brain. The classical isomorphic theory of Gestalt psychology is then reinterpreted in light of my analysis of the geometry of visual space. (shrink)

This is a commentary on Laurence Maloney’s chapter in Mausfeld R., and Heyer, D. (Eds.): Colour Perception: Mind and the Physical World. Oxford: Oxford University Press, 2003. I discuss two related proposals as to the nature of object color formulated by Maloney. On the first proposal colors are photoreceptor excitations; on the second, they are fundamental, universal reflectance characteristics of terrestrial surfaces. I argue that the second proposal is suitable for purposes of color objectivism, whereas the first one is not. (...) However, if we look at Maloney’s – and Brian Wandell’s – models of color vision and color constancy more thoroughly, not even the second version supports absolutist versions of color objectivism, according to which observer-independent reflectance properties determine, or are identical to, the phenomenal character of color experience.

This article seeks the origin, in the theories of Ibn al-Haytham (Alhazen), Descartes, and Berkeley, of two-stage theories of spatial perception, which hold that visual perception involves both an immediate representation of the proximal stimulus in a two-dimensional ‘‘sensory core’’ and also a subsequent perception of the three dimensional world. The works of Ibn al-Haytham, Descartes, and Berkeley already frame the major theoretical options that guided visual theory into the twentieth century. The field of visual perception was the first area (...) of what we now call psychology to apply mathematics, through geometrical models as used by Euclid, Ptolemy, Ibn al-Haytham, and Descartes (among others). The article shows that Kepler’s discovery of the retinal image, which revolutionized visual anatomy and entailed fundamental changes in visual physiology, did not alter the basic structure of theories of spatial vision. These changes in visual physiology are advanced especially in Descartes' Dioptrics and his L'Homme. Berkeley develops a radically empirist theory vision, according to which visual perception of depth is learned through associative processes that rely on the sense of touch. But Descartes and Berkeley share the assertion that there is a two-dimensional sensory core that is in principle available to consciousness. They also share the observation that we don't usually perceived this core, but find depth and distance to be phenomenally immediate, a point they struggle to accommodate theoretically. If our interpretation is correct, it was not a change in the theory of the psychology of vision that engendered the idea of a sensory core, but rather the introduction of the theory into a new metaphysical context.

The question of whether blindsight is a form of unconscious perception continues to spark fierce debate in philosophy and psychology. One side of the debate holds that while the visual information categorized in blindsight is not access-conscious, it is nonetheless a form of perception, albeit a form of unconscious perception. The opposition, by contrast, holds that blindsight is just a form of degraded conscious perception that makes the categorized information harder to access because it is degraded. In this chapter, we (...) address the opposition’s arguments for thinking that blindsight is a form of degraded conscious vision and then argue that the residual awareness found in blindsight is a form of non-perceptual awareness. To back this claim, we examine the residual visual abilities to detect and discriminate colour found in some blindsight patients and show that residual consciousness in blindsight is indirect and lacks the phenomenal character characteristic of conscious vision.

As people age their actions often become entrenched—we might say they are not open to the new; they are less able to adapt; they are stuck in a rut. Indeed, in The Coming of Age (La Vieillesse) Simone de Beauvoir writes that to be old is to be condemned neither to freedom nor to meaning, but rather to boredom (Beauvoir 1996, 461; 486). While in many ways a very pessimistic account of ageing, the text does provide promising moments where her (...) descriptions do capture other possibilities for aged existence. In particular, I turn to Beauvoir’s suggestion that habit can take on a “kind of poetry” since it merges past, present and future in a sense of eternity that the present moment now lacks with its limited futural horizon (468; 492). In this paper, I draw out, delineate, and further explore this phenomenological reconfiguration of the present that she gestures towards through a consideration of the intensification and modification of the present through habit. Drawing as well upon Merleau-Ponty’s insights into the phenomenal body, I argue that poetical habit is an active passivity that allows for the spontaneity of the new out of the sedimentation of corporeal memory, and for the attentive perception of what appears in the present. To disrupt someone’s habitual life is to unanchor that life from the world, from an identity shaped by repetition, by the constancy of a shared reality of things, that is, from the spatial-temporal process of inhabitation, and thus from her ability to engage with others and to disclose the world.

Collapsing three-dimensional space into two violates Lehar's “volumetric mapping” constraint and can cause the visual system to construct illusory transparent regions to replace voxels that would have contained illumination. This may underlie why color constancy is worse in two dimensions, and argues for Lehar to revise his phenomenal spatial model by putting “potential illumination” in empty space.

It is widely held in contemporary philosophy of mind that states with underived representational content are ipso facto psychological states. This view—the Content View—underlies a number of interesting philosophical projects, such as the attempt to pick out a psychological level of explanation, to demarcate genuinely psychological from non-psychological states, and to limn the class of states with phenomenal character. The most detailed and influential theories of underived representation in philosophy are the tracking theories developed by Fodor, Dretske, Millikan and (...) others. Tracking theorists initially hoped to ‘naturalize’ underived representation by showing that although it is distinctively psychological it is not irreducibly so, yet they ended up developing theories of representation that by their own lights don’t pick out a distinctively psychological phenomenon at all. Burge sets out to develop a theory of underived representation that does pick out a distinctively psychological phenomenon. His theory promises to vindicate the Content View and the various philosophical projects that depend on it. In this paper I argue that Burge’s theory dementalizes representation for the same reason tracking theories do: These theories hold that representations are states with underived accuracy conditions, yet such states are found in all sorts of mindless systems, like plants.

What is the relationship between being coloured and looking coloured? According to Alva Noë, to be coloured is to manifest a pattern of apparent colours as the perceptual conditions vary. I argue that Noë’s ‘phenomenal objectivism’ faces similar objections to attempts by traditional dispositionalist theories of colour to account for being coloured in terms of looking coloured. Instead, I suggest that to be coloured is to look coloured in a ‘non-perspectival’ sense, where non-perspectival looks transcend specific perceptual conditions.

This paper argues for the reality of qualia as aspects of phenomenal experience. The argument focuses on color vision and develops a dispositionalist, subjectivist account of what it is for an object to be colored. I consider objections to dispositionalism on epistemological, metaphysical, and 'ordinary' grounds. I distinguish my representative realism from sense-data theories and from recent 'representational' or 'intentional' theories, and I argue that there is no good reason to adopt a physicalist stance that denies the reality of (...) qualia as phenomenally available intentional contents in Brentano's original sense of 'intentionality'.

In this outstanding introduction, Constance Meinwald covers all of Plato's philosophy and shows how he shaped the landscape of Western philosophy. Beginning with a helpful overview of what is known about Plato's life and times, she clearly explains and assesses Plato's fundamental arguments and ideas. These include the importance of Plato's view of what philosophy is and the distinctive way in which his most important arguments are presented in dialogues; his theories of ethics addressed through the fundamental and enduring questions (...) happiness and virtue; his influential treatments of the soul and immortality; the lasting contributions he made to the study of metaphysics and the nature of knowledge through his theory of the Forms; and his enduring and controversial insights into political and social thought in the context of his theories of human nature. Throughout, Constance Meinwwald draws expertly on Plato's most important dialogues to present a thorough and lively picture of his philosophy. Essential reading for students of ancient philosophy and Classics, Plato is an ideal introduction to arguably the greatest of all Western philosophers. (shrink)

The Parmenides is notorious for the criticisms it directs against Plato's own Theory of Forms, as presented in the middle period. But the second and major portion of the dialogue has generally been avoided, despite its being offered as Plato's response to the problems; the text seems intractably obscure, appearing to consist of a series of bad arguments leading to contradictory conclusions. Carefully analyzing these arguments and the methodological remarks which precede them, Meinwald shows that to understand Plato's response we (...) need to recognize his important distinction between two kinds of predication. Read in the light of this distinction, the arguments can be seen to be sound, and the contradictions merely apparent. Meinwald then proceeds to demonstrate the direct application of Plato's crucial innovation in solving the problems of the first part of the dialogue, including the infamous Third Man. On Meinwald's interpretation, the new distinction is associated with developments in metaphysics which take Plato well beyond the problems commonly thought to tell against Platonism. (shrink)

Dans cet article, la pairepros ta alla/pros heautodans leParménidede Platon est analysée dans les termes d’une distinction entre la prédication ordinaire (où un individu présente une qualité) et la prédication en arborescence (fondée sur la relation qui s’établit entre un X et un Y lorsque la nature X fait partie de la nature Y). J’engage une discussion avec mes critiques en soutenant que cette interprétation donne tout leur sens aux remarques méthodologiques de Platon, tout en rendant son argumentation plus efficace. (...) LeParménidefait le pont entre les dialogues de maturité et les développements techniques des derniers dialogues de Platon. (shrink)

This paper argues for a view that maximizes in the Stoics' epistemology the starkness and clarity characteristic of other parts of their philosophy. I reconsider our evidence concerning doxa (opinion/belief): should we really take the Stoics to define it as assent to the incognitive, so that it does not include the assent of ordinary people to their kataleptic impressions, and is thus actually inferior to agnoia (ignorance)? I argue against this, and for the simple view that in Stoicism assent is (...) either, in the case of the fool, doxa = agnoia, or alternatively, in that of the sage, epistêmê (knowledge). This view, together with reflection on the appropriate sense of "between" in the relevant reports of SE and Cicero, yields a sympathetic reading of an otherwise problematic challenge Sextus reports Arcesilaus as having prepared for the Stoic claim that katalêpsis, which is the criterion of truth, is between knowledge and opinion; on my view each side is proceeding in a philosophically legitimate way.

Although neglected by psychology, self-respect has been an integral part of philosophical discussion since Aristotle and continues to be a central issue in contemporary moral philosophy. Within this tradition, self-respect is considered to be based on one's capacity for rationality and leads to behaviors that promote autonomy, such as independence, self-control and tenacity. Self-respect elicits behaviors that one should be treated with respect and requires the development and pursuit of personal standards and life plans that are guided by respect for (...) self and others. In contrast, the psychological concept of self-esteem is grounded in the theories of self-concept. As such, self-esteem is a self-evaluation of competency ratios and opinions of significant others that results in either a positive or negative evaluation of one's worthiness and inclusionary status. The major distinction between the two is that while competency ratios and others' opinions are central to self-esteem, autonomy is central to self-respect. We submit that not only is self-respect important in understanding self-esteem, but that it also uniquely contributes to individual functioning. Research is needed to establish the central properties of self-respect and their effects on individual functioning, developmental factors, and therapeutic approaches. (shrink)
