Paul Churchland has recently argued that empirical evidence strongly suggests that perception is penetrable to the beliefs or theories held by individual perceivers (1988). While there has been much discussion of the sorts of psychological cases he presents, little has been said about his arguments from neurology. I offer a critical examination of his claim that certain efferents in the brain are evidence against perceptual encapsulation. I argue that his neurological evidence is inadequate to his philosophical goals, both by itself (...) and taken in concert with his psychological evidence. (shrink)

David Marr's theory of vision has been a rich source of inspiration, fascination and confusion. I will suggest that some of this confusion can be traced to discrepancies between the way Marr developed his theory in practice and the way he suggested such a theory ought to be developed in his explicit metatheoretical remarks. I will address claims that Marr's theory may be seen as an optimizing theory, along with the attendant suggestion that optimizing assumptions may be inappropriate for cognitive (...) mechanisms just as anti-adaptationists have argued they are inappropriate for other physiological mechanisms. I will discuss the nature of optimizing assumptions and theories. Considering various difficulties in identifying and assessing optimizing assumptions, I will suggest that Marr's theory is not purely an optimizing theory and that reaction to Marr on this issue prompts interesting considerations for the development of inter-disciplinary constraints in the cognitive and brain sciences.

Criticism of the observation/theory distinction generally supposes it to be an empirical fact that even the most basic human perception is heavily theory-laden. I offer critical examination of experimental evidence cited by Thomas Kuhn and Paul Churchland on behalf of this supposition. I argue that the empirical evidence cited is inadequate support for the claims in question. I further argue that we have empirical grounds for claiming that the Kuhnian discussion of perception is developed within an inadequate conceptual framework and (...) that a version of the observation/theory distinction is indeed tenable. The connection between cognitive science and epistemology is also discussed. (shrink)

A large body of research in computational vision science stems from the pioneering work of David Marr. Recently, Patricia Kitcher and others have criticized this work as depending upon optimizing assumptions, assumptions which are held to be inappropriate for evolved cognitive mechanisms just as anti-adaptationists (e.g., Lewontin and Gould) have argued they are inappropriate for other evolved physiological mechanisms. The paper discusses the criticism and suggests that it is, in part, misdirected. It is further suggested that the criticism leads to (...) interesting questions about how one formulates constraints--across "levels of organization" and disciplinary boundaries--on one's models of complex systems, such as human vision.

Block (1995t) has argued for a noncognitive and non- representational notion of phenomenal consciousness, but his putative examples of this phenomenon are conspicuous in their representational and functional properties while they do not clearly possess other phenomenal properties.

The dissertation sketches a solution to the problem of pictorial representation. By appealing to the visual system as an information processing system, we understand how it is that certain sorts of pictures are seen as representing their subjects. ;The first chapter introduces the problem and discusses existing philosophical treatment of pictorial representation. Conventionalist arguments against the possibility of a naturalist account are refuted, thus clearing the way for a naturalist, realist, "resemblance" view of pictorial representation. ;The second chapter discusses the (...) notion of the modularity of mind. Aspects of perceptual holism are criticized. I support the modularist claim that one can make a useful distinction between observation and inference without suffering familiar positivist problems. I suggest that much of vision can fruitfully be studied in isolation from other mental processes. ;The third and fourth chapters provide a contemporary account of human vision. A model of the neural circuitry of vision is provided. Similar treatment is given to mathematical modeling of spatial vision . Also, some attention is paid to lower level biological details and to higher level functional attributes of the system. Research methodologies are discussed, as are the connections between the various levels of investigation. ;The concluding chapter begins with a theoretical and methodological comparison of experimental work cited as empirical foundation for various forms of conventionalism with that supporting modularity . The questions of Chapter I are then reconsidered in light of the vision science of Chapters III and IV. It is shown that current understanding of vision elucidates many of the problems of pictorial representation. Especially relevant is the observation that human spatial vision functions by abstracting certain features from the environment, features that are preserved in certain sorts of pictures. It turns out that many of the conventionalist claims about mind, vision and pictorial representation are unsupportable, given current understanding of mind and vision. (shrink)

A connectionist vehicle theory of consciousness needs to disambiguate its criteria for identifying the relevant vehicles. Moreover, a vehicle theory may appear entirely arbitrary in sorting between what are typically thought of as conscious and unconscious processes.

Various claims for theory-laden perception have involved empirical as well as conceptual considerations. Thomas Kuhn cites New Look psychological research in discussing the role of a paradigm in perception (1970) and Paul Churchland (1988) appeals to biological evidence, as well as New Look sources similar to Kuhn's. This paper offers a critical examination of the empirical evidence cited by Kuhn and Churchland, including a look at the underlying experimental work. It also offers a comment on the application of such evidence (...) in a naturalized epistemology. (shrink)

Of the many controversial claims in Thomas Kuhn’s The Structure of Scientific Revolutions perhaps none are more troublesome than those made in his account of the role of a paradigm in perception. For if we take it that “a paradigm is prerequisite to perception itself (Kuhn 1970, p. 113) and that “two groups of scientists see different things when they look from the same point in the same direction” (Kuhn 1970, p. 150) then we seem to be burdened with all (...) the familiar problems about whether, and how, experimental evidence could possibly serve to promote the acceptance of a paradigm. And, indeed, these problems have been amply discussed in the last several decades. Dudley Shapere, for instance, has questioned Kuhn’s account of how science comes to move between incommensurable paradigms. (Shapere 1964) Still, Kuhn’s discussion of perception has an empirical foundation in psychological research which gives it a certain resilience in the face of surface problems with the consequences of his account.

Identification of those who have the potential to become knowledgeable, skilled, and compassionate physicians, and determining how best to prepare them for medical education has been an on ongoing challenge since the mid-1800s (Ludmerer 1985). When medical education was almost exclusively proprietary, the primary consideration for admission was having adequate financial resources. However, in the late 1800s, two men became the driving forces for structuring medical and premedical education in the United States. Daniel Coit Gilman, of Yale (...) and the University of California, later the founding President of Johns Hopkins University, and Charles W. Eliot, President of Harvard, articulated two radical objectives that .. (shrink)

At the climax of Ender's Game, we see Ender exhausted and at wit's end. Sorting out the mess of who is actually responsible for what is difficult–we feel conflicted about the whole thing, just as Ender does. In this chapter, Aristotle helps us make sense of responsibility and voluntary action and considers whether a person can be responsible for something that he or she did not cause. It looks at why we should care about whether a fictional character is responsible (...) and consider an alternative notion of responsibility that explains Ender's post‐xenocide actions as Speaker for the Dead. The chapter first establishes what moral responsibility is and then contrasts moral responsibility with causal responsibility. He is not to blame for the destruction of the buggers, he does what he can to try to make things right. (shrink)

There has of late been a revival of interest in the problem of practical reason. One of the causes of this revival has been, I think, a reaction against the radical subjectivism to which the emotive theory seemed to lead. Philosophers have wished to show that the method of linguistic analysis can account for that kind of objectivity, whatever kind that might be, which is possessed by our moral opinions, criticisms, etc. The question in what this objectivity consists has, however, (...) remained obscure and recent writing has failed to distinguish at least two quite distinct issues. I hope to show what these are and that they are distinct. (shrink)

It is probable that few critics, if directly challenged, would admit to believing that a work of literature which was, in some sense, morally objectionable was therefore necessarily totally lacking in literary merit. Nevertheless, it is not uncommon for a man—in the language he uses, in the conclusions he draws, in his obiter dicta—to seem yet to hold a view which, in its bald statement, he has denied. Certainly, those critics who most vehemently wish to dissociate themselves from any claims (...) that art exists for art's sake, or that there are peculiarly ‘aesthetic’ criteria, and who believe that such claims lead to irresponsibility, such critics often use moral concepts extensively in their criticism. Furthermore, they often do this in such a way as to suggest that if a work is morally objectionable, then there is no way of redeeming it aesthetically; for, it would seem, moral criticism exhausts the critical possibilities; no aesthetic saving graces are allowed.

This book presents a systematic account of the role of the personal spiritual ideal of wu-wei--literally "no doing," but better rendered as "effortless action"--in early Chinese thought. Edward Slingerland's analysis shows that wu-wei represents the most general of a set of conceptual metaphors having to do with a state of effortless ease and unself-consciousness. This concept of effortlessness, he contends, serves as a common ideal for both Daoist and Confucian thinkers. He also argues that this concept contains within itself a (...) conceptual tension that motivates the development of early Chinese thought: the so-called "paradox of wu-wei," or the question of how one can consciously "try not to try." Methodologically, this book represents a preliminary attempt to apply the contemporary theory of conceptual metaphor to the study of early Chinese thought. Although the focus is upon early China, both the subject matter and methodology have wider implications. The subject of wu-wei is relevant to anyone interested in later East Asian religious thought or in the so-called "virtue-ethics" tradition in the West. Moreover, the technique of conceptual metaphor analysis--along with the principle of "embodied realism" upon which it is based--provides an exciting new theoretical framework and methodological tool for the study of comparative thought, comparative religion, intellectual history, and even the humanities in general. Part of the purpose of this work is thus to help introduce scholars in the humanities and social sciences to this methodology, and provide an example of how it may be applied to a particular sub-field.

This edition goes beyond others that largely leave readers to their own devices in understanding this cryptic work, by providing an entrée into the text that parallels the traditional Chinese way of approaching it: alongside Slingerland's exquisite rendering of the work are his translations of a selection of classic Chinese commentaries that shed light on difficult passages, provide historical and cultural context, and invite the reader to ponder a range of interpretations. The ideal student edition, this volume also includes a (...) general introduction, notes, multiple appendices--including a glossary of technical terms, references to modern Western scholarship that point the way for further study, and an annotated bibliography.
