A focus on the relation between sensation and the perceptual object in the philosophies of G H Mead and Maurice Merleau-Ponty points toward their shared views of perception as non-reductionistic and holistic, as inextricably tied to the active role of the sensible body, and as involving a new understanding of the nature of immediacy within experience. This essay explores these shared views.

Some philosophers have argued recently that the content of perception is either entirely or mainly non- conceptual. Much of the motivation for that view derives from theories of information processing, which are a modern version of ancient considerations about the causal processes underlying perception. The paper argues to the contrary that perception is essentially concept- dependent. While perception must have a structure derived from what is purely sensory, and is thereby dependent on processes involving information in (...) the technical sense which Gibson said amounted to structure, the information which perception provides about the world depends on the concepts which we have.

This paper argues that, assuming some widely held views about how vision justifies beliefs, there is an important epistemic asymmetry between visual perception and the perception of bodily sensations. This asymmetry arises when we consider the epistemic significance of the distinction between low-level and high-level properties in perceptual experience. I argue that a distinction exists between low-level and high-level properties of bodily sensations which parallels that distinction in the objects of visual experience. I then survey evidence revealing systematic (...) unreliability in an important dimension of our perception of low-level bodily sensational properties. I argue that this unreliability results in an epistemic asymmetry with vision. I conclude by sketching some implications of this asymmetry for developing a general, unified theory of perceptual justification. (shrink)

The sensation-perception distinction did not appear before the seventeenth century, but since then various formulations of it have gained wide acceptance. This is not an historical accident and the article suggests an explanation for its appearance. Section 1 describes a basic assumption underlying the sensation-perception distinction, to wit, the postulation of a pure sensory stage--viz. sensation--devoid of active influence of the agent's cognitive, emotional, and evaluative frameworks. These frameworks are passive in that stage. I call (...) this postulation the passivity assumption. Section 2 suggests three major reasons for the emergence of this assumption in the seventeenth century: the mental-physical gap, the causal theory of perception, and epistemological considerations regarding the status of the sensory given. In the last section a critical discussion is presented. The passivity assumption is found to have serious empirical and theoretical flaws. (shrink)

This paper aims to show how some of Wittgenstein's considerations in the Philosophical Investigations speak to the neo-empiricist tendency to give sensation a purely causal, non-epistemic role. As the foil for Wittgenstein's criticisms, I outline the way Wilfred Sellars rehabilitates sensory impressions from his own diagnosis of the Myth of the Given by construing them as purely causal episodes. Sellars' work shows how it is possible to have a keen appreciation of the incoherence of the empiricist model yet to (...) believe that we ought to maintain that model by modifying our account of the role that sensations play in perception. Sellars and Wittgenstein have the same understanding of what a non-epistemic conception of sensations must involve. Wittgenstein articulates the way this conception manifests itself in ordinary thinking while Sellars gives it a sophisticated theoretical elaboration designed to retain what is key for sensory episodes while avoiding traditional problems of givenness. The instructive difference between Sellars and Wittgenstein is that while Sellars believes we can develop a coherent non-epistemic conception, Wittgenstein’s work suggests that we cannot. (shrink)

ABSTRACT The difference between perception and cognition seems introspectively obvious in many cases. Perceiving and thinking have also been assigned quite different roles, in epistemology, in theories of reference and of mental content, in philosophy of psychology, and elsewhere. Yet what is the nature of the distinction? In what way, or ways, do perception and cognition differ? The paper reviews recent work on these questions. Four main respects in which perception and cognition have been held to (...) differ are discussed. First, their phenomenal character, such as the often-remarked vivacity or immediacy of perception. Second, the way in which they represent the world, e.g. the non-propositional nature of the contents, or non-discursive character of the vehicles, that have been held to characterise perceptual representation. Third, their place in cognitive architecture, i.e., roughly, in the information-flow of the mind, such as their alleged (non-)modularity. Fourth, their mind-world relations, e.g. the way in which perceptions seem to be tightly causally linked with distal or proximal stimuli. Against this background, we distinguish some main options for an account of the perception/cognition distinction, in particular concerning whether there is one, several, or no interesting and principled distinction(s) to be drawn here.

It is widely assumed that perception is a source of reasons (SR). There is a weak sense in which this claim is trivially true: even if one characterizes perception in purely causal terms, perceptual beliefs originate from the mind's interaction with the world. When philosophers argue for (SR), however, they have a stronger view in mind: they claim that perception provides pre- or non-doxastic reasons for belief. In this article I examine some ways of developing this view (...) and criticize them. I exploit these results to formulate a series of constraints that a satisfactory account of the epistemic role of perception should fulfil. I also make a positive suggestion: coherentists are right when they claim that only beliefs can be reasons for other beliefs. Nevertheless, I depart from traditional coherentism, for I do not buy its conception of perception as bare sensation, nor explicate the justificatory status of beliefs in terms of coherence. My point is rather that, when one invokes experience to justify a belief, the justifying state must have structural features of beliefs. (shrink)

The theory of visual perception that Irvin Rock develops and supports in this book with numerous original experiments, views perception as the outcome of a process of unconscious inference, problem solving, and the building of structural descriptions of the external world.

This paper reconstructs and defends a Sellarsian approach to “sensation” that allows us to avoid mythological conceptions of it. Part I reconstructs and isolates Sellars’s argument for “sensation,” situating his adverbial interpretation of the notion within his broader theory of perception. Part II positions Sellars’s views vis-à-vis current conversations on adverbalism. In particular, it focuses on the Many Property Problem, which is traditionally considered the main obstacle to adverbialism. After reconstructing Sellars’s response to this problem, I demonstrate (...) that his position is compatible with some current strategies to solving it and can be developed along similar lines. Finally, part III addresses how a Sellarsian adverbial approach productively accounts for the phenomenal properties of experience often understood to fall under the notion of “sensation”. The paper therefore shows how isolating Sellars’s argument can yield a non-problematic conception of sensation. Indeed, the argument on which I focus offers a form of direct realism compatible with recent forms of “new adverbialism”. Although my view remains Sellarsian, to defend it I maintain that some Sellarsian claims about sensation should be resisted as not logically entailed by his argument. (shrink)

The chapter begins with a sketch of the empirical, theoretical, and philosophical background to nineteenth-century theories of perception, focusing on visual perception. It then considers German sensory physiology and psychology in the nineteenth century and its reception. This section gives special attention to: assumptions about nerve–sensation relations; spatial perception; the question of whether there is a two-dimensional representation in visual experience; psychophysics; size constancy; and theories of colour perception. The chapter then offers a brief look (...) at the interaction between perceptual theory and philosophical issues in epistemology and the metaphysics of mind in Britain and America, focusing on: the notion of a muscle sense; the problem of the external world; and forms of perceptual realism. It ends with an overview of psychological theories of perception in the early twentieth century and the Gestalt reaction, culminating with J. J. Gibson. (shrink)

Chapter 1 First Person Access to Mental States. Mind Science and Subjective Qualities -/- Abstract. The philosophy of mind as we know it today starts with Ryle. What defines and at the same time differentiates it from the previous tradition of study on mind is the persuasion that any rigorous approach to mental phenomena must conform to the criteria of scientificity applied by the natural sciences, i.e. its investigations and results must be intersubjectively and publicly controllable. In Ryle’s view, philosophy (...) of mind needs to adopt an antimentalist stance to achieve this aim. Antimentalism not only definitively rejects the idea that mind is a substance separated from the body, it also denies that mental phenomena radically differ from physical phenomena by virtue of several unique features. Most problematically, mental phenomena have a conscious character (mental states are related to specific qualitative feelings) and are accessible only to the first-person (only the subject knows directly what s/he is experiencing inside his/her mind). Ryle takes a strong stance on antimentalism going so far as to maintain that an approach to mind which aims to meet the criteria of scientificity set by the natural sciences must avoid any reference to internal, unobservable mental states. In his view (which is considered a specifically philosophical version of psychological behaviorism and also addresses questions put forward in psychological research), mental states can be redescribed in terms of behavioral dispositions. In this chapter, we address the historical roots of the antimentalist view and analyze its relation to the later tradition of research on mind. We show that, compared to the antimentalist stance, functionalism and cognitivism take a step back when they maintain that direct reference to mental states is necessary since mental states cause and therefore explain human behavior. This step backwards is often interpreted as a return to mentalism. However, this is only partially true. Indeed, we suggest that these later traditions retain one important element of Ryle’s antimentalism, i.e. the idea that mental states must be uniquely identified using external and publicly observable criteria, while excluding any reference to introspection and those qualitative dimensions of a mental state, which are accessible only to the first-person. According to the perspective we put forward, this epistemological stance has continued to influence contemporary research on mind and current philosophical and psychological theories which both tend to exclude the subjective qualities of human experience from their accounts of how the mind works. The issue we raise here is whether this is legitimate or whether subjective qualities do play a role with respect to the way our mind works. The conclusion of this chapter anticipates the argument the book makes in in favor of this latter position, starting from a particular angle, i.e. the problem of how we categorize concepts related to our internal states. -/- Chapter 2 The Misleading Aspects of the Mind/Computer Analogy. The Grounding Problem and the Thorny Issue of Propriosensitive Information -/- Abstract. After the crisis of behaviorism, cognitivism and functionalism became the predominant models in the field of psychology and of philosophy, respectively. Their success is mainly due to the new key they use for interpreting mental processes: the mind/computer analogy. On the basis of this analogy, mental operations are seen as cognitive processes based on computations, i.e. on manipulations of abstract symbols which are in turn understood as informational unities (representations). This chapter identifies two main problems with this model. The first is how these symbols can relate to and communicate with perception and thus allow us to identify and classify what we perceive through the senses. Here we limit ourselves to presenting this issue in relation to the classical symbol grounding problem originally put forward by Harnad on the basis of Searle’s Chinese room argument. An attempt to address the problem raised here will be made in chap. 3. The second point we discuss in relation to the mind/computer analogy concerns the idea of information it fosters. Indeed, following this analogy, information is something available in the external world which can be captured by the senses and transmitted to the central system without being influenced or modified by the procedures of transmission. This perspective does not take into account that – unlike computers – in living beings information is acquired by means of the body. As Ulric Neisser has already pointed out, the body is itself an informational source that provides us with additional sensory experience that influences (modifies or complements) the information extracted from the external world by the senses. To develop this line of analysis and to determine exactly what information is provided by the body and how this might influence cognition, we examine Sherrington’s and Gibson’s positions. Moving on from their views, we qualify bodily information in terms of ‘proprioception’. We use ‘proprioception’ in a broad sense to describe any kind of experience we have of our internal states (including postural information as well as sensations related to the general state of the body and its parts). Following Damasio’s and Craig’s studies, we further elaborate this position, arguing that living beings are equipped with an internal propriosensitive monitoring system which maps all the changes that constantly occur in our body and that give us perceptual (‘proprioceptive’ or propriosensitive) information about what happens inside us. Moreover, relying on Goldie’s and Ratcliffe’s view, we show that emotional information can also be considered as a form of ‘proprioception’ which contributes to determining everything we perceive. This analysis leads us to the second main thesis of this book: ‘proprioception’ is a form of internal perception and it is an essential component of the sensory information we can access and use for all cognitive purposes. -/- Chapter 3 Semantic Competence from the Inside: Conceptual Architecture and Composition -/- Abstract. Concepts are essential constituents of thought: they are the instruments we use to categorize our experience, i.e. to classify things and group them together in homogeneous sets. Here we define concepts as the internal mental information (representations) that allows us, among other things, to master words in natural language. By analyzing the way in which individuals master word meanings we explore a number of hypotheses regarding the nature of concepts. Following Diego Marconi’s research, we differentiate between two kind of abilities that underpin lexical competence – so-called ‘referential’ and ‘inferential competence’ – and we suggest that, in order to support these abilities, concepts must also include two corresponding kinds of information, i.e. inferential and referential information. We point out that the most widely used and acknowledged theories of concepts do not make this distinction, instead broadly characterizing the information used for categorization in terms of propositionally described feature lists. However, we show that while feature lists can explain inferential competence, they do not account for referential competence. To address the issue of referential competence we examine Ray Jackendoff’s hypothesis that to account for the possibility of linking perceptual and conceptual information we need to assume the existence of a (visual) representation that encodes the geometric and topological properties of objects and bridges the gap between the percept and the concept. Furthermore, we analyze the extension of this work by Jesse Prinz who introduced the notion of a proxytype, a perceptual representation of a class of objects that incorporates structural and parametric information related to their appearance. However, as we point out, proxytypes can only explain the relationship between perception and concepts with respect to instances that can be perceived through the senses and that belong to the same class by virtue of their physical similarity. We suggest that this notion be extended to include larger conceptual classes. To accomplish this, we further develop Mark Johnson, George Lakoff and Jean Mandler’s idea of a schematic image and argue that conceptual representations include a perceptual schema. Perceptual schemata are non-linguistic, structured experiential gestalts (patterns or maps) that make use of information taken from all sensory modalities, including body perception. They accomplish a quasi-conceptual function: they allow us to recognize and to classify different instances. In this work, we hypothesize that perceptual schemata are an essential component of concepts, but not identical to them. Instead, we suggest that concepts include both perceptual and propositional information with perceptual schemata providing the ‘perceptual core concept’ that grounds related propositional information. -/- Chapter 4 In the Beginning There Were Categories. The Bodily Origin of Prelinguistic Categorical Organization: The Example of Folkbiological Taxonomies -/- Abstract. Studies of categorization in psychology and the cognitive sciences have made use of the notions of ‘category’ and ‘concept’ without precisely defining what is meant by either; in fact, often these terms have been used as synonyms, making it difficult to address specific issues related to conceptual development. This chapter begins by discussing the definitions of, as well as the distinctions between, ‘categories’ and ‘concepts’ in the classical philosophical tradition (Aristotle, Kant and Husserl). We introduce our view of categories with reference to Husserl. Categorization is defined as the way in which our experience is originally (pre-linguistically) organized in a passive and fully unconscious manner on the basis of universal structuring principles. Conceptualization is explained as a later process in which the earlier categorical macro-classes are further subdivided into more specific and detailed sets; this later process also relies on linguistic learning and exposure to culture. On the basis of Ray Jackendoff, Jean Mandler, George Lakoff and Mark Johnson’s work, we hypothesize that categorization is a two-step process that begins with the formation of homogeneous sets of entities partitioned into regions that describe the ontological boundaries of the objects that humans perceive (categories) and continues at a later stage with the development of more specific classifications (concepts). In this chapter, we mainly address three related issues: Why should we assume that there is categorical organization which precedes the development of a conceptual system? How do categories and concepts relate to each other? Shall we hypothesize that categories are innate or that they are formed before concepts on the basis of information and organizational structure available at a very early developmental stage? We show that categorical partitions are necessary for categorization and, following Mandler, that the general categories we form at an early age do not match our adult superordinate concepts. As for the third issue, we argue that there might be no need to assume that categories are innately present in the human mind, since their formation can be explained – at least in certain cases – by basic mechanisms that work on body (propriosensitive) information. This hypothesis will not be discussed in general, but in relation to a particularly relevant example of categorical partition, i.e. the folk-biological dichotomy between ANIMATE/INANIMATE. This is compared with other dichotomies that derive from it, but are not directly categorical such as LIVING/NON-LIVING and BIOLOGICAL/NON-BIOLOGICAL. -/- Chapter 5 Internal States: From Headache to Anger. Conceptualization and Semantic Mastery -/- Abstract. Here we ask if we can also apply the distinction between referential and inferential competence we introduced in Chapter 3 to words that do not refer to things that are perceived using the external senses, especially to words/concepts that denote bodily experiences (such as pain, thirst, hunger, etc.) or emotions. We introduce and discuss the hypothesis that – even though such words/concepts do not refer to intersubjectively identifiable entities in the external world – they do have a kind of referent that can be accessed via direct perception, more specifically ‘proprioception’, as we have defined it in terms of all propriosensitive information we can consciously access. In the first part of the chapter, we specifically consider terms denoting bodily experiences such as ‘pain’ or ‘hunger’ and argue that their referents are identified and classified from a first-personal point of view on the basis of four main characteristics: their specific intensity, their localization in the body, their co-occurrence with other signals and above all their specific qualitative sensations. Emotions are addressed in the second part of the chapter. We suggest that there is a continuity between bodily experiences and emotions. In particular, we argue for a perceptual theory of emotions in line with that proposed by James and Lange at the end of the 19th century and developed more recently by authors such as Damasio (see also chap. 2§5, §6). The hypothesis we put forward is that the referential information that supports the categorization of emotions and therefore also our mastery of terms referring to emotions consists in the perception (i.e. the ‘proprioception’) of those bodily states and changes in bodily states which constitute our emotional experience. In the context of this discussion we examine some objections to this line of reasoning that arise from a cognitivist perspective and following authors such as Oatley, Johnson-Laird and Frijda, we distinguish between basic emotions that can be identified and classified solely on the basis on how they feel and complex emotions whose identification and classification additionally depends on cognitive factors. To describe how emotions are identified and classified on the basis of how they feel, we rely on Marcel and Lambie’s distinction between an ‘emotion state’ and an ‘emotion experience’. Both notions indicate kinds of feelings that we consciously experience. However, they describe first-order and second order emotion awareness respectively. The emotion state is the feeling we have of the bodily states and changes that occur when we are experiencing an emotion, while the emotion experience is the fully developed and integrated emotion we both experience and are, with reflection, aware of experiencing. On the basis of this differentiation, we also show that the same characteristics that aid in the identification and classification of bodily experiences (specific qualitative sensations; somatic localization; specific intensity; presence/absence of specific concomitant sensations) can also be used for the identification and classification of emotions – at least basic emotions. In the last two sections of the chapter we present some clinical evidence on the semantic competence of people who suffer from Alexithymia and Autism Spectrum Disorder which supports the conclusions of our preceding analyses. -/- Chapter 6 The ‘Proprioceptive’ Component of Abstract Concepts -/- Abstract. In this chapter, we address the issue of whether the mastery of abstract words requires only inferential knowledge and thus, if the concepts that support the mastery of abstract words include only linguistic information. We start by differentiating the notions of ‘abstract’ and ‘general’ which are often erroneously confused. We then identify a strict definition of abstract, as contrasted with ‘concrete’, that applies to words or concepts whose referent cannot be experienced by the senses. We argue that abstract words/concepts would be better described as theoretical, because they are usually conceived as structured sets of inferential knowledge expressed linguistically; that is, as small theories. Pointing out parallels with Carnap’s analysis of this issue in philosophy of science, we hypothesize that words/concepts denoting non-observable entities are not all ‘equally theoretical’, because their link to sensory experience can be stronger or weaker. We revive the distinction, inspired by Quine, between theoretical and intertheoretical concepts/words. This distinction relies on the fact that the former – unlike the latter – retains a strong, although indirect, connection with perception. In Quine’s discussion, perception is understood uniquely in terms of observability, i.e. of external sensory experience. Here we argue, however, that bodily, ‘proprioceptive’ (i.e. propriosensitive) experience can also serve to referentially ground theoretical (i.e. abstract) concepts/words. We frame this issue using the example of the theoretical concept ‘freedom’ and Lakoff’s hypothesis that this concept is developed on the basis of bodily information. We contrast this with the example of ‘democracy’ which more closely resembles an intertheoretical concept/word. Furthermore, we show that one of the classical views put forward in psycholinguistic research to explain how abstract concepts are mentally represented – i.e. Paivio’s Dual Coding Theory – points in the same direction as our analysis. The same is true of Barsalou’s work suggesting that we use internal information to understand at least some abstract words. To sustain this position, we put forward two lines of evidence: the first comes from psycholinguistic studies while the second examines deficits of semantic competence exhibited by people with Autism Spectrum Disorder. On the basis of our analysis, we put forward a classification that distinguishes between different kinds of concreteness and different degrees of abstraction: concepts/words referring to body experiences and basic emotions are described as analogous to concrete concepts/words because they are grounded in perceptual (i.e. propriosensitive) experience, while abstract concepts/words are considered more or less abstract depending on whether they are intratheoretical (and rely entirely on inferential information) or theoretical (and are partially grounded in perceptual – or more often in propriosensitive perceptual – information). In the last section of the chapter we consider two scales that have been used in psycholinguistic research to measure the degree of concreteness vs. abstractness of words and we show that – used conjointly – they can provide a measure of the internal vs. external grounding of specific words.

We enjoy immediate knowledge of our own limbs and bodies. I argue that this knowledge, which is also called proprioception, is a special form of perception, special in that it is, unlike perception by the external senses, at the same time also a form of genuine self-knowledge. The argument has two parts. Negatively, I argue against the view, held by G. E. M. Anscombe and strengthened by John McDowell, that this knowledge, bodily self-knowledge, is non-perceptual. This involves, inter (...) alia, rescuing from McDowell’s attack the very idea of receptive self-knowledge. On the positive side, I develop, by drawing on the work of Brian O’Shaughnessy, a detailed account of bodily self-knowledge as a special form of perception. This account spells out how this special form of perception is epistemologically mediated by sensations of a special class of primary qualities—vital-dynamic sensations as I call them—in one’s limbs.

James argued that time is a sensation, and the main point of this paper is to deny that claim. The concept of the specious present is explained, indicating how it clarifies the concept of "the present moment." But neither it nor an argument used by Mach and James show time to be a sensation. The analysis presented here requires distinguishing concepts of sensation from concepts of temporal relations. James' view is really a theory that time-as-duration is sensed. (...) But this assumes that the description of time as sensed is also a description of time as an objective property of independent events. This is nowhere established, and making it plausible is a recurrent problem for philosophies like neutral monism and radical empiricism. (shrink)

Hamlyn's book is exactly what the subtitle says it is: a history of the philosophy of perception, where this is taken to be a part of what is now called the philosophy of mind, as distinguished from the theory of knowledge. He expounds and criticizes, clearly and carefully, the views of Western philosophers from the pre-Socratics to Ryle and Sartre, and in a final chapter of about ten pages he offers some conclusions of his own. He holds that "in (...) the primary sense, perception can signify any means whereby we come to recognize, identify or characterize something by means of the senses" ; that there is a conceptual connection between perception and sensation, in the sense that "an essential condition of our application of the concept of perception to a being of any kind is that such a being should have sense experiences or sensations" ; but that it is a mistake "to ask what experiences, processes or activities constitute perception... [although] this is just the question which has so often been asked in the history of philosophy and psychology". "An understanding of the concepts of sensation and perception comes... not by asking what experiences, processes or activities these terms stand for. It can come only as the result of an inquiry into the concepts which form the schemes to which these particular concepts belong". These schemes, Hamlyn says, center around the concept of knowledge, and include such concepts as those of identification, recognition, and awareness. (shrink)

In Part I of this essay I distinguish perception from sensation and sensory processing, and I argue that propositional perceiving is an act, intentional, cognitive, and can go amiss. In Part II I show that perceiving must be committive to go amiss, and since a committive, cognitive, intentional act is assentive, I conclude that propositional perceiving is assentive. In Part III of the essay I argue that nonpropositional perceiving is an act, intentional, cognitive, and capable of going amiss, (...) and hence committive. In the course of showing that nonpropositional perceiving is cognitive, I examine Bertrand Russell's views on knowledge by acquaintance and argue that such knowledge is logically propositional. Since nonpropositional perceiving is a committive, cognitive, intentional act, I conclude that it too is assentive. Thus, the conclusion I reach in this work is that the propositional attitude in perception, whether propositional or nonpropositional, is one of assent. (shrink)

In the article two viewpoints on the mind’s influence on perception are considered. One of them was developed on the assumption that perception is a nonproblematic source of knowledge about the world, which is free from mind’s influence— perception as a mirror-image. Another viewpoint is perception as action, i.e. active search and gathering the relevant information, its processing and evaluation. First viewpoint has dominated in philosophy for a long time, the second one has been developing in (...) psychology from the 80th of the 20th century. The aim of the paper is to examine some philosophically significant corollaries from both positions concerning objectiveness, epistemological status of an observation, truth, meaning of name. Analysis showed that perception as action is non-compatible with many traditional concepts, and it goes both against empiricism and against realism as it involves some critical arguments, e.g. theory ladenness of observations, underdetermination of theory by facts, the historical development of a scientific fact.

Originally published in 1964. In four essays, Professor Mandelbaum challenges some of the most common assumptions of contemporary epistemology. Through historical analyses and critical argument, he attempts to show that one cannot successfully sever the connections between philosophic and scientific accounts of sense perception. While each essay is independent of the others, and the argument of each must therefore be judged on its own merits, one theme is common to all: that critical realism, as Mandelbaum calls it, is (...) a viable epistemological position, even though some schools of thought hold it in low esteem.

Seeing, Doing, and Knowing is an original and comprehensive philosophical treatment of sense perception as it is currently investigated by cognitive neuroscientists. Its central theme is the task-oriented specialization of sensory systems across the biological domain. Sensory systems are automatic sorting machines; they engage in a process of classification. Human vision sorts and orders external objects in terms of a specialized, proprietary scheme of categories - colours, shapes, speeds and directions of movement, etc. This 'Sensory Classification Thesis' implies that (...) sensation is not a naturally caused image from which an organism must infer the state of the world beyond; it is more like an internal communication, a signal concerning the state of the world issued by a sensory system, in accordance with internal conventions, for the use of an organism's other systems. This is why sensory states are both easily understood and persuasive.Sensory classification schemes are purpose-built to serve the knowledge-gathering and pragmatic needs of particular types of organisms. They are specialized: a bee or a bird does not see exactly what a human does. The Sensory Classification Thesis helps clarify this specialization in perceptual content and supports a new form of realism about the deliverances of sensation: 'Pluralistic Realism' is based on the idea that sensory systems coevolve with an organism's other systems; they are not simply moulded to the external world. The last part of the book deals with reference in vision. Cognitive scientists now believe that vision guides the limbs by means of a subsystem that links up with the objects of physical manipulation in ways that bypass sensory categories. In a novel extension of this theory, Matthen argues that 'motion-guiding vision' is integrated with sensory classification in conscious vision. This accounts for the quasi-demonstrative form of visual states: 'This particular object is red', and so on. He uses this idea to cast new light on the nature of perceptual objects, pictorial representation, and the visual representation of space. (shrink)
