A judge springs out of his car on the way to court in downtown Chicago and takes photographs of an inflatable rat. A while later he inserts these photographs into a decision involving another inflatable rodent. Judges now regularly insert pictures in judgments, but there is no study either of the genres or the precedential status of these modern visual emblemata, these pictorial interventions in the record. Using a comparative visual corpus of over three hundred images extracted from diverse (...) common law jurisdictions, the practice of retinal justice, the novelty of vision in decision, is here anatomized, choreographed, and critically classified.

Examining various aspects of how Kepler’s discovery of retinal images was received in the field of philosophy, this article questions the meaning of the Keplerian dictum “ut pictura, ita visio”. In what sense could we say that vision is just like the physiological picture formed at the back of the eye? We show that with this question arises an opposition between two theoretical options – a tension that is rarely pointed out: The first option views physiological pictures ( (...) class='Hi'>retinal or cerebral) as the proximal, internal objects of perception, inspected by the soul on the very body of the eye or brain, while the second considers that vision, although indexed on the picture, is never directed upon it, the picture being merely the causal antecedent of an act of direct perception of the external world.

Available from UMI in association with The British Library. Requires signed TDF. ;Metaphor and analogy are the scaffolding of science. Kepler's theory of the retinal picture could not have been built without the analogy between an eye and a camera obscura, and, two hundred and fifty years later, Charles Darwin devoted most of the first chapter of The origin of Species to discussion of pigeon fanciers. Unlike Darwin, Kepler was bewitched by his own imagination and was led to wonder (...) "how this image or picture is joined to the visual faculty, which is situated in the retina and in the nerve, and whether it is placed within the hollows of the brain, before the soul or tribunal of the visual faculty, or whether the visual faculty, like a magistrate sent by the soul from the administrative chamber of the brain, descends into the optic nerve or retina to meet this image, as though to a lower court" . ;The theory of the retinal image answered the crucial question of medieval optics: the scaffolding had served its purpose and should have been dismantled. Instead, Kepler mistook it for a part of the building: what he construed as a scientific problem was nothing more than the extension of a metaphor. As a result, and in spite of his remarkable achievement, he left the theory of vision in a state of confusion. ;I intend to show that Descartes revolutionized visual theory by manipulating the pair of analogies which had dominated visual theory since its inception and by advancing a theory of depiction which has since become orthodox. Advocates of the first analogy suggest that seeing the world is rather like seeing pictures of it; Kepler's analogy between the eye and a camera obscura, which was anticipated by Leonardo de Vinci, was a variation on this theme. Advocates of the second analogy compare vision to the use of a walking-stick: the air transmits an impression of a visible object to the eye rather as a walking-stick enables us to find our way around in the dark by transmitting pressures to the hand. As I shall show, Descartes' rejection of the pictorial analogy in favour of the walking-stick analogy and his theory of depiction were designed to salvage Kepler's theory of the retinal picture, a pearl of great price, from its murky setting. ;Descartes aimed to show that whilst Kepler's theory of the retinal picture correctly described the optics of the eye, the pictorial analogy was misleading and stood in the way of a mechanistic theory of perception. ;Current visual theory is Cartesian in some respects and un-Cartesian in others. The walking-stick analogy is no longer used, but the explanatory pattern that it served to illustrate is adhered to closely where the perception of brightness and colour are concerned, and the causal theory of depiction commands widespread support. At the same time, the pictorial analogy has not lost its appeal. (shrink)

Action is a means of acquiring perceptual information about the environment. Turning around, for example, alters your spatial relations to surrounding objects and, hence, which of their properties you visually perceive. Moving your hand over an object’s surface enables you to feel its shape, temperature, and texture. Sniffing and walking around a room enables you to track down the source of an unpleasant smell. Active or passive movements of the body can also generate useful sources of perceptual information (Gibson 1966, (...) 1979). The pattern of optic flow in the retinal image produced by forward locomotion, for example, contains information about the direction in which you are heading, while motion parallax is a “cue” used by the visual system to estimate the relative distances of objects in your field of view. In these uncontroversial ways and others, perception is instrumentally dependent on action. According to an explanatory framework that Susan Hurley (1998) dubs the “Input-Output Picture”, the dependence of perception on action is purely instrumental: "Movement can alter sensory inputs and so result in different perceptions… changes in output are merely a means to changes in input, on which perception depends directly" (1998: 342). -/- The action-based theories of perception, reviewed in this entry, challenge the Input-Output Picture. They maintain that perception can also depend in a noninstrumental or constitutive way on action (or, more generally, on capacities for object-directed motor control). This position has taken many different forms in the history of philosophy and psychology. Most action-based theories of perception in the last 300 years, however, have looked to action in order to explain how vision, in particular, acquires either all or some of its spatial representational content. Accordingly, these are the theories on which we shall focus here. -/- We begin in Section 1 by discussing George Berkeley’s Towards a New Theory of Vision (1709), the historical locus classicus of action-based theories of perception, and one of the most influential texts on vision ever written. Berkeley argues that the basic or “proper” deliverance of vision is not an arrangement of voluminous objects in three-dimensional space, but rather a two-dimensional manifold of light and color. We then turn to a discussion of Lotze, Helmholtz, and the local sign doctrine. The “local signs” were felt cues for the mind to know what sort of spatial content to imbue visual experience with. For Lotze, these cues were “inflowing” kinaesthetic feelings that result from actually moving the eyes, while, for Helmholtz, they were “outflowing” motor commands sent to move the eyes. -/- In Section 2, we discuss sensorimotor contingency theories, which became prominent in the 20thcentury. These views maintain that an ability to predict the sensory consequences of self-initiated actions is necessary for perception. Among the motivations for this family of theories is the problem of visual direction constancy—why do objects appear to be stationary even though the locations on the retina to which they reflect light change with every eye movement?—as well as experiments on adaptation to optical rearrangement devices (ORDs) and sensory substitution. -/- Section 3 examines two other important 20th century theories. According to what we shall call the motor component theory, efference copies generated in the oculomotor system and/or proprioceptive feedback from eye-movements are used together with incoming sensory inputs to determine the spatial attributes of perceived objects. Efferent readiness theories, by contrast, look to the particular ways in which perceptual states prepare the observer to move and act in relation to the environment. The modest readiness theory, as we shall call it, claims that the way an object’s spatial attributes are represented in visual experience can be modulated by one or another form of covert action planning. The bold readiness theory argues for the stronger claim that perception just is covert readiness for action. -/- In Section 4, we move to the disposition theory, most influentially articulated by Gareth Evans (1982, 1985), but more recently defended by Rick Grush (2000, 2007). Evans’ theory is, at its core, very similar to the bold efferent readiness theory. There are some notable differences, though. Evans’ account is more finely articulated in some philosophical respects. It also does not posit a reduction of perception to behavioral dispositions, but rather posits that certain complicated relations between perceptual input and behavioral provide spatial content. Grush proposes a very specific theory that is like Evans’ in that it does not posit a reduction, but unlike Evans’ view, does not put behavioral dispositions and sensory input on an undifferentiated footing.

Our visual system not only mediates information about the visual environment but is capable of generating pictures of nonexistent worlds: afterimages, illusions, phosphenes, etc. We are ''aware'' of these pictures just as we are aware of the images of natural, physical objects. This raises the question: is the neural correlate of consciousness (NCC) of such images the same as that of images of physical objects? Images of natural objects have some properties in common with afterimages (e.g., stability of (...) verticality) but there are also obvious differences (e.g., images maintain size constancy, whereas afterimages follow Emmert's Law: when seen while screens at different distances are observed, an afterimage looks larger, the greater the distance of the screen). The differences can be explained by differences in the retinal extent of images and afterimages, which favors the view that both have the same NCC. It seems reasonable to assume that before neural activity can produce awareness, all the computations necessary for a veridical representation of, e.g., an object, must be completed within the neural substrate and that information characteristic of a particular object must be available within the NCC. Given these assumptions, it can be shown that no retinotopic (in a strict sense) cortical areas can serve as the NCC, although some type of topographic representation is necessary. It seems also to be unlikely that neurons classified as cardinal cells alone can serve as NCC. (shrink)

The complex sensation of vision begins with the relatively simple photoisomerization of the visual pigment chromophore 11-cis-retinal to its all-trans configuration. This event initiates a series of biochemical reactions that are collectively referred to as phototransduction, which ultimately lead to a change in the electrochemical signaling of the photoreceptor cell. To operate in a wide range of light intensities, however, the phototransduction pathway must allow for adjustments to background light. These take place through physiological adaptation processes that rely primarily (...) on Ca2+ ions. While Ca2+ may modulate some activities directly, it is more often the case that Ca2+-binding proteins mediate between transient changes in the concentration of Ca2+ and the adaptation processes that are associated with phototransduction. Recently, combined genetic, physiological, and biochemical analyses have yielded new insights about the properties and functions of many phototransduction-specific components, including some novel Ca2+-binding proteins. Understanding these Ca2+-binding proteins will provide a more complete picture of visual transduction, including the mechanisms associated with adaptation, and of related degenerative diseases.

Change blindness illustrates a remarkable limitation in visual processing by demonstrating that substantial changes in a visual scene can go undetected. Because these changes can ultimately be detected using top–down driven search processes, many theories assign a central role to spatial attention in overcoming change blindness. Surprisingly, it has been reported that change blindness can occur during blink-contingent changes even when observers fixate the changing location [O’Regan, J. K., Deubel, H., Clark, J. J., & Rensink, R. A. . Picture changes (...) during blinks: Looking without seeing and seeing without looking. Visual Cognition, 7, 191–212]. However, eye blinks produce a transient disruption of vision that is independent of any associated changes in the retinal image. We determined whether these ‘attentive blank stares’ could occur in the absence of blink-mediated visual suppression. Using a flicker change-blindness paradigm we confirm that despite direct attentive fixations, obvious scene changes often remain undetected. We conclude that change detection involves object or feature based attentional mechanisms, which can be ‘misdirected’ despite the allocation of spatial attention to the position of the change.

In lieu of an abstract, here is a brief excerpt of the content:The Place of Touch in the ArtsChristopher Perricone (bio)IntroductionIn Breughel's great picture, The Kermess, the dancers go round, they go round and around, the squeal and the blare and the tweedle of bagpipes, a bugle and fiddles tipping their bellies (round as the thick- sided glasses whose wash they impound) their hips and their bellies off balance to turn them. Kicking and rolling about the Fair Grounds, swinging their (...) butts, those shanks must be sound to bear up under such rollicking measures, prance as they dance In Breughel's great picture, The Kermess.1"The Dance" written by William Carlos Williams in 1944 is one of my favorites. Williams gives us a feel for that life of the kermess (a carnival) in his poem through Breughel's picture, as it were three times removed from the event itself. Of course, unlike Plato, I would argue that the vitality of the kermess is not lost in the poem; it is actually enhanced by a subtle sleight of hand. The poem is not primarily about Breughel's picture. It is about dance, about the dancers who go round, their squeal, the crude music, its rollicking measures, the dancers kicking and rolling and swinging, their hips, bellies, and butts. Reading this poem, I "see" those ordinary folk of Breughel's great picture. I "hear" their music. I "move" to their dance. The poem seems a condensation, a summary of the fine arts. Perhaps the poem is about poetry's power to reinvigorate imaginatively what we hear and see. Perhaps I think of festivities at which I have danced, how such festivities are essential to the human experience. Perhaps William Carlos Williams in 1944, World War II coming to a close, was anticipating similar good times.Tactile ValuesThe fine arts do much to educate our senses. One need only recall the many essays and books written on art, on how to look and hear, how various [End Page 90] critics draw our attention to the power of imagery and song. The well-formed visual and auditory sensations we gain from the arts are, as it were, the melody of those experiences. They are the pictures we store away, the tunes we whistle. However, here I want to draw attention to an overlooked sense—touch. I want to argue that touch is the bass line to the melody of sight and hearing in the arts, that is, that touch keeps the artwork coherent and grounded.This is an old idea. Bernhard Berenson had the idea when he was examining the painters of the Italian Renaissance. In a sense this article is a resurrection of Berenson's idea of "tactile values." Berenson was on to something both about painting and about the arts in general. However, he lacked the scientific evidence about touch and its role in human relationships needed to develop his idea of tactile values to any great extent.The idea of tactile values is first mentioned at the beginning of the essay "The Florentine Painters." Berenson is discussing the art of Giotto. However, prior to plunging into his subject, he says that we need to know what is essential to figure painting before we can appreciate its real value. What is essential are the "tactile values" we give to our retinal impressions, "a test of reality."2 Painting stimulates touch in order for it to stimulate our "tactile imagination."3 Giotto was a genius in stimulating the tactile imagination. Like other medieval masters, Giotto was a fine story teller and had great compositional skills. However, unlike Giotto, other medieval masters "never painted a figure which has artistic existence."4 Giotto's predecessors crafted "highly elaborate, very intelligible symbols, capable, indeed, of communicating something, but losing all higher value the moment the message is delivered."5 If such medieval symbols communicated anything at all, it was only some residue of what one might touch; whatever reality those symbols might have possessed was virtually eviscerated by the artists' emphasis on form and cognitive content. Giotto's predecessors were driven merely by ideas and, one might add, not altogether consistent and coherent ones. On the contrary, Giotto's work seemed to... (shrink)

Emotion modulates our time perception. So far, the relationship between emotion and time perception has been examined with visible emotional stimuli. The present study investigated whether invisible emotional stimuli affected time perception. Using continuous flash suppression, which is a kind of dynamic interocular masking, supra-threshold emotional pictures were masked or unmasked depending on whether the retinal position of continuous flashes on one eye was consistent with that of the pictures on the other eye. Observers were asked to (...) reproduce the perceived duration of a frame stimulus that was concurrently presented with a masked or unmasked emotional picture. As a result, negative emotional stimuli elongated the perceived duration of the frame stimulus in comparison with positive and neutral emotional stimuli, regardless of the visibility of emotional pictures. These results suggest that negative emotion unconsciously accelerates an internal clock, altering time perception. (shrink)

It’s a platitude – which only a philosopher would dream of denying – that whereas words are connected to what they represent merely by arbitrary conventions, pictures are connected to what they represent by resemblance. The most important difference between my portrait and my name, for example, is that whereas my portrait and I are connected by my portrait’s resemblance to me, my name and I are connected merely by an arbitrary convention. The first aim of this book is (...) to defend this platitude from the apparently compelling objections raised against it, by analysing depiction in a way which reveals how it is mediated by resemblance. -/- It’s natural to contrast the platitude that depiction is mediated by resemblance, which emphasises the differences between depictive and descriptive representation, with an extremely close analogy between depiction and description, which emphasises the similarities between depictive and descriptive representation. Whereas the platitude emphasises that the connection between my portrait and me is natural in a way the connection between my name and me is not, the analogy emphasises the contingency of the connection between my portrait and me. Nevertheless, the second aim of this book is to defend an extremely close analogy between depiction and description. -/- The strategy of the book is to argue that the apparently compelling objections raised against the platitude that depiction is mediated by resemblance are manifestations of more general problems, which are familiar from the philosophy of language. These problems, it argues, can be resolved by answers analogous to their counterparts in the philosophy of language, without rejecting the platitude. So the combination of the platitude that depiction is mediated by resemblance with a close analogy between depiction and description turns out to be a compelling theory of depiction, which combines the virtues of common sense with the insights of its detractors.

Scientists typically use a variety of representations, including different kinds of figures, to present and defend hypotheses. In order to understand the justification of scientific hypotheses, it is essential to understand how visual representations contribute to scientific arguments. Since the logical understanding of arguments involves the truth or falsity of the representations involved, visual representations must have the capacity to bear truth in order to be genuine components of arguments. By drawing on Goodman's analysis of symbol systems, and on Tarski's (...) work on truth, I show that the figures used in science meet this criterion. (shrink)

Aristotle’s works on natural science show that he was aware of the affective powers of colour. At De an. 421a13, for example, he writes that hard-eyed animals can only discriminate between frightening and non-frightening colours. In the Nicomachean Ethics, furthermore, colours are the source of pleasures and delight. These pleasures, unlike the pleasures of touch and taste, neither corrupt us nor make us wiser. Aristotle’s views on the affective powers of colours raise a question about the limits he seems to (...) place on the affective powers of pictures at De an. 427b15-24, where he implies that pictures do not affect us immediately. In this paper, I examine the contrast between the affective powers of colour and the affective powers of pictures. I argue that colours can give rise to pleasure and pain in themselves and generate emotions incidentally. Similarly, pictures can please us or affect us in themselves and incidentally. In light of this account, I suggest that, on a plausible reading of De an. 427b15-24, the affective powers of pictures as mimetic objects are not immediate because they require an intervening cause in order to be effective. The representations of pictures and statues affect us either with the mediation of deception or with the mediation of interpretation. (shrink)

We intuitively make a distinction between _lying_ and _misleading_. On the explanation of this phenomenon favored here—the _adverbial_ account—the distinction tracks whether the content and its truth-committing force are literally conveyed. On an alternative _commitment_ account, the difference between lying and misleading is predicated instead on the strength of assertoric commitment. One lies when one presents with full assertoric commitment what one believes to be false; one merely misleads when one presents it without full assertoric commitment, by merely hinting or (...) otherwise implying it. Now, as predicted by the well-supported assumption that we can also assert with pictures, the lying/misleading distinction appears to intuitively show up there too. Here I’ll explain how the debate confronting the two accounts plays out both in general and in that case, aiming to provide support for the adverbial account. (shrink)

Kendall Walton has recently claimed that the notion of fictionality is more fundamental and philosophically relevant than the distinction between (works of) fiction and (works of) non-fiction. In this chapter, I argue that one of the reasons why the latter distinction is important is precisely that it affects what turns out to be fictional or true in a representational work. This is specifically relevant for Walton’s view – many of the examples he uses to show that his (former) notion of (...) fictionality is flawed – those that are photographic in nature – depend on an implicit classification of those works as fiction or non-fiction. This being the case, even if it is true that the notion of fictionality is more fundamental than categorizing a work as fiction or non-fiction, the former depends partly on the latter. My second aim in this chapter is to clarify the consequences that Walton’s reconsidered view of fictionality has for his theory of pictorial representation. Paying attention to the examples he uses to argue for his new view on fictionality makes it clear that his account of depiction, despite being modelled on his notion of fictionality, is relevantly different from it.

This chapter explores the cognitive and moral significance of the kind of imaginative experience poetry offers. It identifies two forms of imaginative experience that are especially important to poetry: ‘experiencing-as’ and ‘experience-taking’. Experiencing-as is ‘inherently first-personal, embodied, and phenomenologically characterized’ while in experience-taking one ‘takes the perspective of another, simulating some aspect or aspects of his psychology as if they were his own’. Through a sensitive and probing reading of Paul Celan’s Psalm, the chapter shows the role these two forms (...) of experience play in producing the unique form of ethical and epistemic value poetry can bear. The chapter’s argument for this has important implications for our understanding of the poetic imagination and nature of our experience of meaning in poetic contexts. (shrink)

It is widely assumed that the art media can be individuated with reference to the sense modalities. Different art media are perceived by means of different sense modalities, and this tells us what properties of each medium are aesthetically relevant. The case of pictures appears to fit this principle well, for pictures are deemed purely and paradigmatically visual representations. However, recent psychological studies show that congenitally and early blind people have the ability to interpret and make raised‐line drawings (...) through touch. This shows that pictures are not essentially visual representations. The view that pictures are essentially visual follows from influential views of the nature of depiction and of the nature of vision that are mistaken. By rooting out the mistake, we learn something about pictures, something about vision, and something about the doctrine that art media are individuated by the sense modalities. (shrink)

In this paper, I will investigate Wittgenstein’s idea about the context-sensitivity of utterance. It is the idea that there is a big gap between understanding a sentence in the sense of knowing the idioms and discerning the grammar in it, and what is said by using it in a particular context. Although context-sensitivity in this moderate sense is a familiar idea in Wittgensteinian scholarship, it has mainly been studied as an idea in “Wittgenstein’s philosophy of language.” However, Wittgenstein’s interest in (...) language is always connected with his interest in the treatment of philosophical problems. Therefore, what is lacking in those preceding studies is the study of the relation between Wittgenstein’s engagement with the idea of context-sensitivity and his philosophical therapy. Therefore, I shall investigate that relation and show that Wittgenstein’s philosophical method cannot be intelligible without taking context-sensitivity into consideration and Wittgenstein’s focus on context is deeply connected with his method for treating philosophers’ “pictures.” Below, I will examine recent debates on grammar, and argue that the standard interpretation is untenable once proper consideration is given to context-sensitivity. Next, I will argue that context-sensitivity is important because it gives us a good grasp of the process of a philosopher’s being caught in a picture by citing the discussion about mental process and about the Augustinian picture and rule-following in Philosophical Investigations. Finally, I will talk about the significance of my interpretation for contemporary arguments about philosophical methods. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Erotic Art and Pornographic PicturesJerrold LevinsonOnly in primitive art, with its urgent need to evoke the sources of fertility, are the phallus and the vulva emphasized, as it were innocently. By ancient Greek and Roman times there already existed the special category of the pornographic—graphic art or writing supposed, like a harlot, or porne, to sexually stimulate.1IAS REGARDS PHILOSOPHICAL ANALYSIS of the opposition between the erotic and the pornographic, (...) there are a number of reasonable goals one might have: to preserve as many considered intuitions about the opposition as possible; to present the opposition in a clearer light than it enjoys when casually invoked; to modestly "sharpen" the standard opposition that either accounts for our experience in this domain more fully, or allows us to organize our thinking about the domain more perspicuously. I hope in this paper to make progress toward some of those goals. Though the scope of the erotic/pornographic opposition goes beyond the visual, my focus here will be the opposition as it exists in the visual sphere, and even more narrowly, in the sphere of images. In addition to preserving and clarifying a distinction between erotic art and pornography, I hope also to make an intelligible place for erotica, as something intermediate between the other two.Here, then, are some intuitions on the erotic and the pornographic: [End Page 228]1. the erotic and the pornographic are both concerned with sexual stimulation or arousal.2. while the term "erotic" is neutral or even approving, the term "pornographic" is pejorative or disapproving.3. while "erotic art" is a familiar, if somewhat problematic, notion, "pornographic art" seems an almost oxymoronic one.4. whereas pornography has a paramount aim, namely, the sexual satisfaction of the viewer, erotic art, even if it also aims at sexual satisfaction on some level, includes other aims of significance.5. whereas we appreciate (or relish) erotic art, we consume (or use) pornography. In other words, our interactions with erotic art and pornography are fundamentally different in character, as reflected in the verbs most appropriate to the respective engagements.In what follows I try to accommodate all of those intuitions. As I will need a distinction invoked in the first of them (between sexual stimulation and sexual arousal) let me spell that out before proceeding. By sexual stimulation I will mean the inducing of sexual thoughts, feelings, imaginings, or desires that would generally be regarded as pleasant in themselves. By sexual arousal I mean the physiological state that is prelude and prerequisite to sexual release, involving in the male, at least, some degree of erection. And by sexual release I mean something that I take it needs no spelling out.How to differentiate erotic art from pornography, and from erotica as well, is of course not the only important philosophical question about erotic art. Here are two others: 1) How is the erotic aspect of erotic art compatible with the disinterested or distanced frame of mind that seems required for aesthetic engagement with or appreciation of a work of visual art? 2) How is the degree of eroticness of a work of erotic art related to its artistic value? I will briefly address those two questions toward the end of the paper, but most of my effort will be devoted to the prior question, that of the differentiation of erotic art, erotica, and pornography.IIHow, then, to effect that differentiation in the domain of visual images to which I have restricted my inquiry? One possibility would [End Page 229] concern the specific kind of response aimed at. Thus, erotic art might be said to involve images intended to sexually stimulate, but also to reward artistic interest; erotica to involve images intended to sexually stimulate but not to reward artistic interest; pornography to involve images intended to sexually arouse in the interests of sexual release. Another possibility would be by the character of the sexual representation involved, so that pornography would involve sexually explicit images, erotic art would involve sexually inexplicit images, and erotica images would be intermediate in their explicitness, irrespective of the ends for which the images were fashioned. A third possibility would be by... (shrink)

This paper focuses on whether static images can depict motion. It is natural to say that pictures depicting objects caught in the middle of a dynamic action—such as Henri Cartier-Bresson’s (1932) Behind the Gare St. Lazare—are pictures of movement, but, given that pictures themselves do not move, can we make sense of such an idea? Drawing on results from experimental psychology and cognitive sciences, I show that we can. Psychological studies on implicit motion and representational momentum indicate (...) that motion is really perceived in some static images: our visual system is built in order to detect motion, even where it is only implied, and to anticipate the probable outcomes of others’ actions—even when the ‘others’ are only the subject matters of pictures’. I argue that, consequently, a range of popular depiction theories—perceptualist theories of depiction—can accommodate depicted motion. (shrink)

This book presents an original theory of the nature of pictorial representation. The most influential recent theory of depiction, put forward by Nelson Goodman, holds that the relation between depictions and what they represent is entirely conventional. Flint Schier argues to the contrary that depiction involves resemblance to the things depicted, providing a sophisticated defence of our basic intuitions on the subject. Canvassing an attractive theory of 'generativity' rather than resemblance, Dr Schier provides a detailed account of depiction, showing how (...) it illuminates and resolves many of the enigmas of pictorial representation while remaining true to our basic intuitions on the subject. Philosophers, psychologists and art theorists will find this a sophisticated and stimulating treatment of one of the central topics in aesthetics. (shrink)

It has been argued that picture perception is sometimes, but not always, ‘inflected’. Sometimes the picture’s design ‘inflects’, or is ‘recruited’ into the depicted scene. The aim of this paper is to cash out what is meant by these metaphors. Our perceptual state is different when we see an object fact to face or when we see it in a picture. But there is also a further distinction: our perceptual state is very different if we perceive objects in pictures (...) in an inflected or uninflected manner. The question is what this difference amounts to. My answer is that it is a difference of attention. In the case of inflected, but not uninflected, picture perception, we are consciously attending to certain properties: to relational property that cannot be fully characterized without reference to both the picture’s design and to the depicted object. I defend this way of interpreting inflected picture perception from some important objections and emphasize the importance of this, inflected, way of perceiving pictures. (shrink)

ABSTRACTIn the present study, attentional bias was investigated as a potential predisposing mechanism for the contamination-related subtype of obsessive-compulsive disorder. Fifty healthy participants with varying degrees of subclinical C-OC symptoms performed a visual search task to measure differential attentional biases elicited by neutral, disgust-, and fear-specific pictorial material. Participants had to find a target picture within five neutral distractor pictures randomly presented on different locations in an array. The task was to decide whether the array contained an unpleasant target (...) picture or not. In randomly-selected emotional trials, participants were further asked about the content of the picture and the confidence of their answer. The results show that the reaction times significantly differed between the emotional and neutral pictures. Participants were significantly more confident in answering questions referring to fear compared to disgust pictures. This effect was mar... (shrink)

There has been a long tradition of characterizing man as the animal that talks. However, the remarkable ability of using pictures also only belongs to human beings, after all we know empirically so far. Are there conceptual reasons for that coincidence? Such a question belongs to the philosophy of language just as well as to philosophical visualistics. Comparing the two abilities to use words or pictures yields several similarities as well as distinctions. A well-known conceptual disparity between (...) class='Hi'>pictures and words appears in their relation to perception: the difference can be further determined in an act-theoretic manner by four modes of use of the sign vehicles during the corresponding sign acts. Furthermore, the figure/ground dichotomy means something different for language uses and picture uses. In both cases, however, there is a close relation to the function of context building, by which humans are able to communicate not only with respect to the present situation of behavior but with respect to arbitrary contexts as well. Although the structural comparison does clarify the conceptual relations, it cannot explain that the conceptual structure ought to be like that. Therefore, the paper concludes with the programme of a "concept-genetic" consideration of the two abilities (i.e., to use propositional language or to use pictures) that is able to give us such a foundation.

A simple introduction to numbers and their meanings.

This is indeed a fallacy, if the relevant sort of consistency is logical consistency. However, the expression “is consistent with” is often used by scientists to mean something much stronger, something like confirms or even strongly confirms.
