Roy Sorensen’s adventure in Shadowland started with his prize-winning article, "Seeing Intersecting Eclipses" (published in The Journal of Philosophy, and chosen by the board of the Philosopher’s Annual as one of the ten best philosophy articles of 1999), which is the basis for the first two chapters in this book. The recipe adopted in that article is followed in most of the following thirteen chapters, five of them being based on Sorensen’s previous articles on the topic: start with an open (...) mind regarding the existence and causal efficacy of absences, shadows, i.e. absences of light, in our case, devise a riddle involving perception of such absences, and draw the consequences for the philosophy of perception and/or ontology.

Failure to take note of distinctive attributes in the distal stimulus leads to an inadequate proximal encoding. Representation of similarities in Chorus suffers in this regard. Distinctive qualities may require additional complex representation (e.g., reference to linguistic terms) in order to facilitate discrimination. Additional semantic information, which configures proximal attributes, permits accurate identification of true veridical stimuli.

This article proposes an object properties approach to object perception. By thinking about objects as clusters of co-instantiated features that possess certain canonical higher-order object properties we can steer a middle way between two extreme views that are dominant in different areas of empirical research into object perception and the development of the object concept. Object perception should be understood in terms of perceptual sensitivity to those object properties, where that perceptual sensitivity can be explained in a manner consistent with (...) the graded representation approach adopted by some connectionist modellers. The object properties approach does justice to the differences between a perceptual system solving the binding problem, on the one hand, and genuinely perceiving objects, on the other, without running into the theoretical problems associated with treating young infants as 'little scientists'.

The historically most central epistemological issue concerning perception, to which this article will be almost entirely devoted, is whether and how beliefs about physical objects and about the physical world generally can be justified or warranted on the basis of sensory or perceptual experience—where it is internalist justification, roughly having a reason to think that the belief in question is true, that is mainly in question (see the entry justification, epistemic: internalist vs. externalist conceptions of). This issue, commonly referred to (...) as “the problem of the external world,” divides into two closely related sub-issues, which correspond to the first two main sections below. The first of these issues has to do with the nature of sensory experience and its relation to the physical world; it is typically (though as we shall see not altogether perspicuously) formulated as the question of what are the immediate objects of awareness in sensory experience or, in a variant but essentially equivalent terminology, of what is given in such experience. Perhaps the most historically standard, though not currently the most popular answer to this question has been that it is sense-data (private, non-physical entities that actually have the immediately experienced sensory qualities) that are the immediate objects of awareness or that are given. The second issue has to do with the way in which beliefs about the physical world are justified on the basis of such sensory experience. If it is concluded that physical objects are not themselves given, the two main answers to this question are representationalism or indirect realism (the view that the immediate objects of experience represent or depict physical objects in a way that allows one to infer justifiably from such experience to the existence of the corresponding “external” objects) and phenomenalism (the view..

The problem of cortical integration is described and various proposed solutions, including grandmother cells, cell assemblies, feed-forward structures, RAAM and synchronization, are reviewed. One method, involving complex attractors, that has received little attention in the literature, is explained and developed. I call this binding through annexation. A simulation study is then presented which suggests ways in which complex attractors could underlie our capacity to reason. The paper ends with a discussion of the efficiency and biological plausibility of the proposals as (...) integration mechanisms for different regions and functions of the brain. (shrink)

Still, it is equally clear that this gives us all a (...) perfectly respectable initial conception of what we are talking about; and it is an entirely adequate starting point for what follows.

The question how to account for illusion has had a prominent role in shaping theories of perception throughout the history of philosophy. Prevailing philosophical wisdom today has it that phenomena of illusion force us to choose between the following two options. First, reject altogether the early modern empiricist idea that the core subjective character of perceptual experience is to be given simply by citing the object presented in that experience. Instead we must characterize perceptual experience entirely in terms of its (...) representational content. Second, retain the early modern idea that the core subjective character of experience is simply constituted by the identity of its direct objects, but admit that these must be mind-dependent entities, distinct from the mind-independent physical objects we all know and love. I argue here that the early modern empiricists had an indispensable insight. The idea that the core subjective character of perceptual experience is to be given simply by citing the object presented in that experience is more fundamental than any appeal to perceptual content, and can account for illusion, and indeed hallucination, without resorting to the problematic postulation of any such mind-dependent objects.

I respond to three arguments aimed at establishing that natural kind properties occur in the experiential content of visual experience: the argument from phenomenal difference, the argument from mandatory seeing, and the argument from associative agnosia. I conclude with a simple argument against the view that natural kind properties occur in the experiential content of visual experience.

I defend indirect perceptual realism against two recent and related charges to it offered by A. D. Smith and P. Snowdon, both stemming from demonstrative reference involving indirect perception. The needed aspects of the theory of demonstratives are not terribly new, but their connection to these objections has not been discussed. The groundwork for my solution emerges from considering normal cases of indirect perception (e.g., seeing something depicted on a television) and examining the role this indirectness plays in demonstrative assertions. (...) I argue that indirectness routinely if not typically plays a justificatory role in such judgements, and not a semantic one, and that the same can be said of such judgements when considered within the indirect realist framework. The denial of this, on my analysis, is essential to the criticisms of Snowdon and Smith. The discussion is extended to include scenarios involving the sorts of misconceptions Smith employs. (shrink)

A central preoccupation of philosophy in the twentieth century was to determine constitutive conditions under which accurate (objective) empirical representation of the macrophysical environment is possible. A view that dominated attitudes on this project maintained that an individual cannot empirically represent a physical subject matter as having specific physical characteristics unless the individual can represent some constitutive conditions under which such representation is possible. The version of this view that dominated the century's second half maintained that objective empirical representation of (...) the physical environment requires the individual to be able to supplement this representation with representation of general constitutive features of objectivity. This essay criticizes instances of this version in P. F. Strawson and Quine. It maintains that all versions of the position postulate conditions on objective empirical representation that are more intellectual than are warranted. Such views leave it doubtful that animals and human infants perceptually represent elements in the physical environment. By appeal to common sense and to empirical perceptual psychology, this essay argues that unaided perception yields objective representation of the macrophysical environment. It does so in prelinguistic animals, even in animals that almost surely lack propositional attitudes. The essay concludes with explications of nondeflationary conceptions of representation and perception. It distinguishes nonperceptual sensing from perceptual representation and explicates perceptual representation as a type of objective sensory representation. Objectivity is marked by perceptual constancies. Representation is marked by a nontrivial role for veridicality conditions in explanations of the relevant states.

Although appearances may deceive them, agents are capable of achieving their ends; this success is frequently explained by the fact that the agents may, for example, see a stick in water as bent without believing that it is actually bent. Although the notion of 'seeing as' is supposed to both bridge the gap between experience and action and explain our reaction to illusions, such accounts break down because of their exclusive focus on visual episodes and their tendency to interpret the (...) metaphysics of agency in a psychologistic fashion. This paper shows that 'seeing as' needs to be understood as a species of the genus 'taking as.' The genus admits a wider array of expression, in terms of the kinds of attitudes, actions, and epistemological statuses involved. Such an analysis allows us to avoid the problems of 'seeing as' accounts and deepens our understanding of the relationship between practical and theoretical reason. (shrink)

A sensible quality is a perceptible property, a property that physical objects (or events) perceptually appear to have. Thus smells, tastes, colors and shapes are sensible qualities. An egg, for example, may smell rotten, taste sour, and look cream and round.1,2 The sensible qualities are not a miscellanous jumble—they form complex structures. Crimson, magenta, and chartreuse are not merely three different shades of color: the first two are more similar than either is to the third. Familiar color spaces or color (...) solids capture, to a greater or lesser extent, these relations between the colors. The same goes for sensible qualities perceived in other modalities: middle C, high C, and D are not merely three different notes, and the taste of lemons, oranges, and sugar cubes are not merely three different tastes. How can this structure of appearance be explained? One idea is that sensible qualities are of two sorts: basic and derived. The basic sensible qualities are the building blocks from which the derived sensible qualities can be.. (shrink)

Classic texts that define the disjunctivist theory of perception.

This essay surveys the varieties of disjunctivism about perceptual experience. Disjunctivism comes in two main flavours, metaphysical and epistemological.

Suppose your conscious life were surgically excised, but everything else left intact, what would you miss? In this situation you would not have the slightest idea what was going on. You would have no idea what there is in the world around you; what the grounds are of the potentialities and threats are that you are negotiating. Experience of your surroundings provides you with knowledge of what is there: with your initial base of knowledge of what the things are that (...) you are thinking and talking about. But this connection between consciousness of the objects and properties around you, and knowledge of the references of the basic terms you use, has proven difficult to articulate. The connection cannot be recognized so long as you think of consciousness as a kind of glow with which representations are accompanied or enlivened. It is, though, also possible to think of perceptual experience as fundamentally a relation between the subject and the things experienced; and given such a conception, we can make visible the link between consciousness and reference.

Ir IS winmx HELD that the capacity for spatial thought depends upon the ability to refer to physical things. The argument is that the identification of places depends upon the identification of things; places in themselves are all very much alike and can be distinguished only by their spatial relations to things. So one could not so much as think about places unless one could think about things (Strawson, 1959). It has to be acknowledged that our identifications of places are (...) greatly enriched by our ability to refer to physical things. But, as we shall see, it is possible to identify places without identifying objects. 'Ihis raises the question whether there is any fundamental role that physical objects do play in our spatial thinking. I begin with the ways in which reference to physical objects enriches our capacity to identify places. We shall then consider whether reference to places as such demands reference to objects, and if not, what special role there might be for physical things in spatial thinking. A physical object has a certain causal structure. We can bring this out by reflecting on the way in which the properties of a physical thing affect its behaviour. Some of the properties of a thing just are propensities for it to behave in particular ways in particular circumstances. For example, being elastic, or brittle, are dispositional charac- 'teristics, they say that the thing will behave one way rather than another under pressure. But other properties of a thing, such as its size and.. (shrink)

The papers by Macpherson, O’Callaghan, and Batty reveal some startling differences in the objects and properties represented by different modalities. They also reveal some tensions between different ways of understanding what it is for any one modality to represent objects and properties.

Drawing upon the work of Merleau-Ponty, Borrett et al. (2000) have attempted to model the primordial, "empty heads turned towards the world." Putting the issue of embodiment aside for another day, they propose two separate models, one of movement and the other of perception. While I am sympathetic to the point of their project, I argue in this commentary that their models are insufficiently vague. The following analytic abstractions to which they commit themselves seem seriously at odds with the nature (...) of their task: action versus perception; vision versus the other senses; spatial properties versus, for example, colour and meaning; and 'a controller' versus the body and its environment.

Heyes's proposed study for testing whether chimpanzees have a theory of mind is (1) too strong because it requires that the animals apply mental concepts to the interpretation of both their own experiences and the behaviours of others, and (2) too weak because dispositional rather than representational understanding of “seeing” is sufficient to pass it.

Evidence from aphasia is considered that leads to a distinction between abstract and concrete thought processes and hence for a distinction between rules and similarity. It is argued that perceptual classification is inherently a rule-following procedure and these rules are unable to be followed when a patient has difficulty with name comprehension and retrieval.

Although Barsalou is right in identifying the importance of perceptual symbols as a means of carrying certain kinds of content, he is wrong in playing down the inferential resources available to amodal symbols. I argue that the case for perceptual symbol systems amounts to a false dichotomy and that it is feasible to help oneself to both kinds of content as extreme ends on a content continuum. The continuum thesis I advance argues for the inferential content at one end and (...) perceptual content at the other. In between the extremes, symbols might have aspects that are either perceptual or propositional-linguistic in character. I argue that this way of characterising the issue preserves the good sense of Barsalou's recognition of perceptual representations and yet avoids the tendency to minimise the gains won with symbolic representations vital to contemporary cognitive science.

Comparisons between modally and amodally completed regions show that perceptual filling-in is not merely the ignoring of absences. Illusory filled-in colour arises for modal completion, but not for amodal completion in comparable displays. We find that attention spreads automatically to modally but not amodally completed regions from their inducers, revealing a functional effect of filled-in colour.

It is common both in philosophy and in the cognitive sciences (broadly understood as ranging from, say, neuroscience to developmental or evolutionary psychology) to distinguish between two kinds of hallucinations.1 What differentiates them is whether they are subjectively indistinguishable from genuine perceptions and therefore mistaken by us for the latter. While perceptual (or ‘true’) hallucinations cannot, from the subject’s perspective, be told apart from perceptions, non-perceptual (or ‘pseudo’) hallucinations can and usually are. Sometimes, when subjects, say, auditorily hallucinate someone else (...) calling their name or commenting on their behaviour, they are able to realise, on the basis of how they subjectively experience their episode of hallucination, that they are not perceiving real speech: their hallucination is non-perceptual. This happens, for instance, when subjects suffering from schizophrenia or other illnesses hear ‘inner voices’ speaking to them. But in other circumstances, the subjects concerned are - even under conditions of proper mental health and rationality - in no position to recognise the hallucinatory status of their experience without the help of some external evidence: their hallucination is perceptual. Wrongly hearing the phone ringing while taking a shower, say, is a good example of this kind of hallucination.2 When philosophers speak or write about hallucinations, they usually concentrate on perceptual hallucinations. One reason for this is the fact that philosophers tend to address the topic of hallucination, not for its own sake, but only in the context of some wider issues. Thus, when they are discussing hallucinations, they are primarily interested in other topics, such a how - or whether - we are able to acquire knowledge about the external world, in which sense our mental states are directed at objects and properties, how best to account for what our experiences are subjectively like, which features suffice for something to count as a conscious experience, and so on..

Abstract: In Mind and World, McDowell conceives of the content of perceptual experiences as conceptual. This picture is supposed to provide a therapy for skepticism, by showing that empirical thinking is objectively and normatively constrained. The paper offers a reconstruction of McDowell's view and shows that the therapy fails. This claim is based on three arguments: 1) the identity conception of truth he exploits is unable to sustain the idea that perception-judgment transitions are normally truth conducing; 2) it could be (...) plausible only from an externalist point of view that is in tension with the view of normativity that motivates conceptualism; 3) the identity conception of truth is incompatible with McDowell's recent version of conceptualism in terms of ‘non-propositional intuitive contents’.

Shepard's analysis of how shape, motion, and color are perceptually represented can be generalized. Apparent motion and shape may be associated with a group of spatial transformations, accounting for rigid and plastic motion, and perceived object color may be associated with a group of illuminant transformations, accounting for the discriminability of surface-reflectance changes and illuminant changes beyond daylight. The phenomenological and mathematical parallels between these perceptual domains may indicate common organizational rules, rather than specific ecological adaptations. [Barlow; Hecht; Kubovy & (...) Epstein; Schwartz; Shepard; Todorovic]. (shrink)

This new heuristic model of perceptual analysis raises interesting issues but in the end falls short. Its arguments are more in the Cartesian than Gestalt tradition. Much of the argument is based on setting up theoretical straw men and ignores well known perceptual and brain science. Arguments are reviewed in light of known physiology and traditional Gestalt theory.

In Action in Perception, Alva Noë provides a persuasive account of the “enactive” approach to perception, according to which perception is not simply based on the processing of sensory information, or on the construction of internal representations, but is fundamentally shaped by the motor possibilities of the perceiving body. As John Dewey put it in 1896, in his essay, “The Reflex Arc Concept in Psychology”.

In the course of his discussion of perception, Searle criticizes representative theories in general. In this paper I will argue that, even though his criticisms may be adequate regarding a certain form of these theories, perhaps the most frequently defended by philosophers of perception, a version I will outline here escapes to them. A second issue I raise concerns Searle's claim that his theory of perception is a form of direct realism. I will raise difficulties for Searle's attempt to maintain (...) at the same time a "token-reflexive" theory of perception and the thesis of direct realism. (shrink)

To balance Kubovy & Epstein, I evaluate the relationship between Shepard and Gestalt theorists along three dimensions. First, both discover internal universals by reducing external support. Second, they share strengths and weaknesses of the minimum principle. Third, although their attitudes toward an evolutionary account of perception is superficially different, they are fundamentally similar with respect to the internalization process. [Kubovy & Epstein; Shepard].

Many philosophers and scientists rightly take hallucinations to be phenomena that challenge in a most pressing way our theories of perception and cognition, and epistemology in general. However, very few challenge the received views on the hallucinatory experience and even fewer critically delve into the subject with both breadth and depth. There are all kinds of problems concerning hallucinations—including conceptual, methodological, and empirical issues—that call for a multilevel analysis and an interdisciplinary approach which in turn provide the detail and scope (...) that the subject demands. In this paper, I present and briefly discuss four interrelated problems: (1) definitions, (2) dependence on perception, (3) two views on hallucinations, and (4) methodology. Neglect or underestimation of these problems, among other things, continue to prevent a proper understanding of the concept and the corresponding experience, giving rise to misconceptions and even plain myths on the subject. Hallucinations do occur; but in order to productively investigate them (for whatever end), we first need to get clear on the concept and develop a suitable epistemological framework for their analysis.

Theories of perception and of memory are closely allied. The binding problem (which considers how bits of perception are reassembled by the brain) leads to neurophysiological subjectivism. This could be outflanked by arguing with Bergson that perceiving consciousness is out in the world. Thus the brain would bind only behavioral “maps.” In turn, consciousness would retain our personal pasts. Such personal (episodic) memories both help us to recognize present objects and to perform creative acts. Memory, although retentive, is also creative. (...) This is important in rethinking biological and evolutionary memory. (shrink)

Contemporary philosophical debates about causation are dominated by two approaches, which are often referred to as difference-making and causal process approaches to causation, respectively. I provide a characterization of the dialectic between these two approaches, on which that dialectic turns crucially on the question as to whether our common sense concept of causation involves a commitment to locality – i.e., to the claim that causal relations are always subject to spatial constraints. I then argue that we can extract from existing (...) work on perceptual judgement (specifically work that invokes the notion of a simple theory of perception) materials for an argument in favour of a positive answer to that question, and that this work can also help to bring out a distinctive kind of role that a commitment to locality plays in our reasoning about causal relationships.

1. I take my question from Robert Brandom, who remarks in his Study Guide (167): “The title of this essay is ‘Empiricism and the Philosophy of Mind,’ but Sellars never comes right out and tells us what his attitude toward empiricism is.”1 Brandom goes on to discuss a passage that might seem to indicate a sympathy for empiricism on Sellars’s part, but he dismisses any such reading of it. (I shall come back to this.) He concludes: “Indeed, we can see (...) at this point [he has reached §45] that one of the major tasks of the whole essay is to dismantle empiricism” (168). I am going to argue that this claim is quite wrong. To do Brandom justice, I should note that when he defends his claim, what he mentions is, specifically, traditional empiricism. But he nowhere contemplates a possibility left open by this more detailed (and correct) specification of Sellars’s target — the possibility that Sellars might be aiming to rescue a non-traditional empiricism from the wreckage of traditional empiricism, so that he can show us how to be good empiricists. I think that is exactly what Sellars aims to do in this essay. (shrink)

He speaks about the body and the world, the coexistence of space and things, the unfortunate optimism of science – and also the insidious stickiness of honey, and the mystery of anger.' - James Elkins Maurice Merleau-Ponty was one of the most important thinkers of the post-war era. Central to his thought was the idea that human understanding comes from our bodily experience of the world that we perceive: a deceptively simple (...) argument, perhaps, but one that he felt had to be made in the wake of attacks from contemporary science and the philosophy of Descartes on the reliability of human perception. From this starting point, Merleau-Ponty presented these seven lectures on The World of Perception to French radio listeners in1948. Available in a paperback English translation for the first time in the Routledge Classics series to mark the centenary of Merleau-Ponty’s birth, this is a dazzling and accessible guide to a whole universe of experience, from the pursuit of scientific knowledge, through the psychic life of animals to the glories of the art of Paul Cézanne.

This book offers a comprehensive and broadly rationalist theory of the mind which continually tests itself against experimental results and clinical data. Taking issue with Empiricists who believe that all knowledge arises from experience and that perception is a non-cognitive state, Norton Nelkin argues that perception is cognitive, constructive, and proposition-like. Further, as against Externalists who believe that our thoughts have meaning only insofar as they advert to the world outside our minds, he argues that meaning is determined 'in the (...) head'. Finally, he offers an account of how we acquire some of our most basic concepts, including the concept of the self and that of other minds. (shrink)

The world shows up to perceptual consciousness in virtue of the deployment of distinct sensorimotor and also conceptual skills.

Once upon a time, people thought that all perception was conscious. Indeed, it was widely believed that all mental states are conscious, so the problem of explaining consciousness collapses into the problem of explaining mentality. But things have changed. Most people now believe that a lot goes on unconsciously. Indeed, some people believe that mental states that are not perceptual in nature are never conscious. That’s a matter of controversy. Less controversial is the claim that perceptual states are conscious some (...) of the time, but not all of the time. This raises a question. When are perceptual states conscious? A theory of consciousness is, in large part, an answer to that question. In this chapter, I will offer a few critical remarks on one answer that has been popular in philosophy, and then I will offer a defense of another answer that has emerged out of cognitive science. To avoid undue suspense, the answer that I favor is that perceptual states become conscious when and only when the perceiver is attending. (shrink)

In the "Transcendental Aesthetic" of the Critique of Pure Reason, Kant offers an argument for transcendental idealism. This argument is one focus of the longstanding controversy between "one-world" and "two-world" interpretations of the distinction between things in themselves and things as they appear. I present an interpretation of the argument of the "Aesthetic" that supports a novel "one-world" interpretation. On this interpretation, Kant is concerned with the mind-dependence of spatial and temporal properties; and with the idea that space and time (...) can be identified with mental objects. I end by arguing that, for Kant, even on a "one-world" interpretation, we do not know the nature or even the existence of mind-independent things. (shrink)

Pylyshyn's target article argues that perception is not inferential, but this is true only under a narrow construal of inference. A more general construal is possible, and has been used to provide formal theories of many visual capacities. This approach also makes clear that the evolution of natural constraints need not converge to the “veridical” state of the world.

This chapter discusses the causal requirements on perceptual success in putative cases of the perception of absence – in particular, in cases of hearing silence and seeing darkness. It is argued that the key to providing the right account of the respect in which we can perceive silence and darkness lies in providing the right account of the respect in which we can have conscious perceptual contact with intervals of time and regions of space within which objects can potentially be (...) perceived. In this account, a significant explanatory role is assigned to comparatively invariant structural features of our conscious experience of regions of space and intervals of time. The chapter discusses how the explanatory role assigned to these structural features affects our view of the causal requirements on perceptual success. (shrink)

One might think that a healthy respect for the deliverances of experience would require us to give up any claim to nontrivial a priori knowledge.
