John Searle's Speech Acts (1969) and Expression and Meaning (1979) developed a highly original and influential approach to the study of language. But behind both works lay the assumption that the philosophy of language is in the end a branch of the philosophy of the mind: speech acts are forms of human action and represent just one example of the mind's capacity to relate the human organism to the world. The present book is concerned with these biologically fundamental capacities, and, (...) though third in the sequence, in effect it provides the philosophical foundations for the other two. Intentionality is taken to be the crucial mental phenomenon, and its analysis involves wide-ranging discussions of perception, action, causation, meaning, and reference. In all these areas John Searle has original and stimulating views. He ends with a resolution of the 'mind-body' problem. (shrink)

Visual Agnosia is a comprehensive and up-to-date review of disorders of higher vision that relates these disorders to current conceptions of higher vision from cognitive science, illuminating both the neuropsychological disorders and the nature of normal visual object recognition.Brain damage can lead to selective problems with visual perception, including visual agnosia the inability to recognize objects even though elementary visual functions remain unimpaired. Such disorders are relatively rare, yet they provide a window onto how the normal brain might accomplish the (...) complex task of vision. Visual Agnosia reviews a century of case studies of higher-level visual deficits following brain damage, places them in the general context of current neuroscience, and draws relevant conclusions about the organization of normal visual processing. It is unique in drawing on research in cognitive psychology, computational vision, visual neurophysiology, and neuropsychology to interpret the agnosias and draw inferences from them about visual object recognition.Following a historical account of agnosia research, Visual Agnosia offers a taxonomy of a wide range of agnosia syndromes, describing and interpreting the syndromes in terms of the latest theoretical models of visual processing and ultimately bringing them to bear as evidence on a variety of questions in the study of higher vision.Martha J. Farah is Associate Professor of Psychology at Carnegie Mellon University. Visual Agnosia is included in the Issues in Biology of Language and Cognition series, edited by John Marshall. (shrink)

A common objection to sense-datum theories of perception is that they cannot give an adequate account of the fact that introspection indicates that our sensory experiences are directed on, or are about, the mind-independent entities in the world around us, that our sense experience is transparent to the world. In this paper I point out that the main force of this claim is to point out an explanatory challenge to sense-datum theories.

"Perception is not something that happens to us, or in us," writes Alva Noe. "It is something we do." In Action in Perception, Noe argues that perception and perceptual consciousness depend on capacities for action and thought — that ...

What is the nature of, and what is the relationship between, external objects and our visual perceptual experience of them? In this book, Frank Jackson defends the answers provided by the traditional Representative theory of perception. He argues, among other things that we are never immediately aware of external objects, that they are the causes of our perceptual experiences and that they have only the primary qualities. In the course of the argument, sense data and the distinction between mediate and (...) immediate perception receive detailed defences and the author criticises attempts to reduce perceiving the believing and to show that the Representative theory makes the external world unknowable. Jackson recognises that his views are unfashionable but argues in detail that they are to be preferred to their currently favoured competitors. It will become an obvious point of reference for all future work on the philosophy of perception. (shrink)

This book presents an attempt to develop a theory of knowledge and a philosophy of mind using ideas derived from the mathematical theory of communication developed by Claude Shannon. Information is seen as an objective commodity defined by the dependency relations between distinct events. Knowledge is then analyzed as information caused belief. Perception is the delivery of information in analog form for conceptual utilization by cognitive mechanisms. The final chapters attempt to develop a theory of meaning by viewing meaning as (...) a certain kind of information-carrying role. (shrink)

Consciousness is a mongrel concept: there are a number of very different "consciousnesses." Phenomenal consciousness is experience; the phenomenally conscious aspect of a state is what it is like to be in that state. The mark of access-consciousness, by contrast, is availability for use in reasoning and rationally guiding speech and action. These concepts are often partly or totally conflated, with bad results. This target article uses as an example a form of reasoning about a function of "consciousness" based on (...) the phenomenon of blindsight. Some information about stimuli in the blind field is represented in the brains of blindsight patients, as shown by their correct "guesses," but they cannot harness this information in the service of action, and this is said to show that a function of phenomenal consciousness is somehow to enable information represented in the brain to guide action. But stimuli in the blind field are BOTH access-unconscious and phenomenally unconscious. The fallacy is: an obvious function of the machinery of access-consciousness is illicitly transferred to phenomenal consciousness. (shrink)

Traditionally, perceptual experiences—for example, the experience of seeing a cat—were thought to have two quite distinct components. When one sees a cat, one’s experience is “about” the cat: this is the representational or intentional component of the experience. One’s experience also has phenomenal character: this is the sensational component of the experience. Although the intentional and sensational components at least typically go together, in principle they might come apart: the intentional component could be present without the sensational component or vice (...) versa.

This chapter analyzes aspects of the relationship between consciousness and intentionality. It focuses on the phenomenal character and the intentional content of perceptual states, canvassing various possible relations among them. It argues that there is a good case for a sort of representationalism, although this may not take the form that its advocates often suggest. By mapping out some of the landscape, the chapter tries to open up territory for different and promising forms of representationalism to be explored in the (...) future. In particular, it argues for a nonreductive, narrow, and Fregean variety of representationalism, which contrasts strongly with more widely explored varieties. It concludes with some words about the fundamental relationship between consciousness and intentionality. (shrink)

Little, Brown, 1992 Review by Glenn Branch on Jul 5th 1999 Volume: 3, Number: 27.

Anydomainofscientificresearchhasitssustainingorthodoxy. Thatis, research on a problem, whether in astronomy, physics, or biology, is con- ducted against a backdrop of broadly shared assumptions. It is these as- sumptionsthatguideinquiryandprovidethecanonofwhatisreasonable-- of what "makes sense." And it is these shared assumptions that constitute a framework for the interpretation of research results. Research on the problem of how we see is likewise sustained by broadly shared assump- tions, where the current orthodoxy embraces the very general idea that the business of the visual system is to (...) create a detailed replica of the visual world, and that it accomplishes its business via hierarchical organization and by operatingessentiallyindependently of other sensorymodalitiesas well as independently of previous learning, goals, motor planning, and motor execution.

In this paper, I explore and defend the idea that we have epistemic responsibilities with respect to our visual searches, responsibilities that are far more fine-grained and interesting than the trivial responsibilities to keep our eyes open and “look hard”. In order to have such responsibilities, we must be able to exert fine-grained and interesting forms of control over our visual searches. I present both an intuitive case and an empirical case for thinking that we do, in fact, have such (...) forms of control over our visual searches. I then show how these forms of control can be used to aim the visual beliefs that result from our searches towards various epistemic goals. (shrink)

It is often claimed that the phenomenal character of visual experience is 'transparent' in that the phenomenal features of visual experience do not seem 'mental'. It is then claimed that this transparency speaks in favour of some theories of experience while speaking against others. In this paper, I advance both a negative and a positive thesis about transparency. My negative thesis is that visual phenomenal character is reticent in that it does not reveal whether it is mental or non-mental in (...) nature. This, in turn, means that, by itself, transparency does not speak in favour of (and against) the theories it is often thought to speak in favour of (and against). My positive thesis is that the phenomenon referred to as the 'transparency' of visual phenomenal character is best characterized in spatial, not mental, terms. (shrink)

This book maintains that our conception of consciousness and cognition begins with and depends upon a few fundamental errors. Thau elucidates these errors by discussing three important philosophical puzzles - Spectrum Inversion, Frege's Puzzle, and Black-and-White Mary - each of which concerns some aspect of either consciousness or cognition. He argues that it has gone unnoticed that each of these puzzles presents the very same problem and, in bringing this commonality to light, the errors in our natural conception of consciousness (...) and cognition are also reviewed.

Michael Tye has recently argued that the phenomenal character of conscious experiences is "one and the same as" (1) Poised (2) Abstract (3) Non-conceptual (4) Intentional Content (PANIC). Tye argues extensively that PANIC Theory accounts for differences in phenomenal character in representational terms. But another task of a theory of phenomenal consciousness is to account for the difference between those mental states that have phenomenal character at all and those that do not. By going through each of the four qualifiers (...) of PANIC, we argue that PANIC Theory fails to account for this difference in genuinely representational terms. We suggest, furthermore, that the reasons it fails are likely to be endemic to all representational theories of phenomenal consciousness. (shrink)

Gilbert Harman (1990) seeks to defend psychophysical functionalism by articulating a representationalist view of the qualities of experience. The negative side of the present paper argues that the resources of this representationalist view are insufficient to ground the evident distinction between perception and (mere) thought. This failure makes the view unable to support the uses to which Harman wishes to put it. Several rescuing moves by other representationalists are considered, but none is found successful. Part of the difficulty in Harman's (...) (...) work is that he does not adequately specify the view he rejects. The positive aim of the present paper is to provide a robust intrinsic quality account of experience that offers advantages in comparison with Harman's view, and that plainly does not fall to any of the arguments he advances.

Memory is a single word that refers to a complex and fascinating set of abilities which people and other animals possess that enables them to learn from experience and retain what they learn. In memory, an experience affects the nervous system, leaves a residue or trace, and changes later behavior. Types of memory are tremendously varied; so, too, are the techniques used in cognitive science to investigate them. The aim of the present chapter is to give an overall sense of (...) types of memory as well as of techniques used in the experimental study of memory. The process of remembering will be broken up into two main components: encoding and retrieval. We shall then discuss the factors which determine the effectiveness of each component and some of the ways in which memory both succeeds and fails. (shrink)

There is now a considerable literature that goes under the heading of “phenomenal intentionality.” But it features a number of distinct issues. What they have in common is the claim that intentionality bears a closer relation to phenomenology than had previously been recognized. There is a basic thesis, which is controversial, and there are further arguments attempting to draw more exciting morals from the basic thesis. My purpose in this paper is to survey these issues, see what may be at (...) stake, and adjudicate. (shrink)
