This paper contrasts three different schemes of reference relevant to understanding systems of perceptual representation: a location-based system dubbed "feature-placing", a system of "visual indices" referring to things called "proto-objects", and the full sortal-based individuation allowed by a natural language. The first three sections summarize some of the key arguments (in Clark, 2000) to the effect that the early, parallel, and pre-attentive registration of sensory features itself constitutes a simple system of nonconceptual mental representation. In particular, feature integration--perceiving something as (...) being both F and G, where F and G are sensible properties registered in distinct parallel streams--requires a referential apparatus. Section V. reviews some grounds for thinking that at these earliest levels this apparatus is location-based: that it has a direct and nonconceptual means of picking out places. Feature-placing is contrasted with a somewhat more sophisticated system that can identify and track four or five "perceptual objects" or "proto-objects", independently of their location, for as long as they remain perceptible. Such a system is found in Zenon Pylyshyn's fascinating work on "visual indices", in Dana Ballard's notion of deictic codes, and in Kahneman, Treisman, and Wolfe's accounts of systems of evanescent representations they call "object files". Perceptual representation is a layered affair, and I argue that it probably includes both feature-placing and proto-objects. Finally, both nonconceptual systems are contrasted with the full-blooded individuation allowed in a natural language. (shrink)

I am very grateful to my commentators for their interest and their careful attention to A Theory of Sentience. It is particularly gratifying to find other philosophers attracted to the murky domain of pre-attentive sensory processing, an obscure place where exciting stuff happens. I can by no means answer all of their objections or counter-arguments, and some of the problems noted derive from failures in my original exposition. But a theory is a success if it helps spur the creation of (...) better successors. By those lights this one seems to be succeeding admirably. Would that every author could receive such commentaries!

Drawing on work in psychophysics, psychometrics, and sensory neurophysiology, Clark analyzes the character and defends the integrity of psychophysical explanations of qualitative facts, arguing that the structure of such explanations is sound and potentially successful.

This is part of a complete set of Jane Austen's novels collating the editions published during the author's lifetime and previously unpublished manuscripts. The books are illustrated with 19th century plates and incorporate revisions by experts in the light of subsequent research.

Drawing on the findings of neuroscience, this text proposes and defends the hypothesis that the various modalities of sensation share a generic form that the author, Austen Clark, calls feature-placing.

El objetivo de este estudio es interpretar la relación entre el modelo anatómico de Descartes y el régimen disciplinario que M. Foucault propone en su tesis sobre el poder en la Modernidad. Se muestra cómo Foucault sitúa a Descartes como el iniciador de una medicina que convertiría el cuerpo humano en una máquina y al igual que esta, pasaría a concebirse como un sistema mecánico susceptible de ser explorable, controlable y manipulable.

Many philosophers doubt that one can provide any successful explanation of sensory qualities - of how things look, feel, or seem to a perceiving subject. To provide such an explanation, one would need to explain qualitative facts in non-qualitative terms. Attempts to construct such explanations have seemed, in principle, doomed. Austen Clark examines the strategy used in psychophysics, psychometrics, and sensory neurophysiology to explain qualitative facts. He argues that this strategy could succeed: its structure is sound, and it can (...) answer the various philosophical objections lodged against it. On this basis Professor Clark presents an analysis of senosry qualities that offers the possibility of explaining at least some qualia, and he sketches how this scheme might eventually reduce to neurophysiology. If he is correct, we are not doomed to an eternity of mere acquaintance with our qualia. (shrink)

Este estudio examina la tesis de Th. W. Adorno por la cual el arte es una actividad racional. En primer lugar, se focaliza la cuestión de la relación arte y racionalidad. En segundo lugar, se explora la cuestión de la participación del arte en el proceso de la dialéctica de la Ilustración. En tercer lugar, el trabajo indaga el potencial crítico del arte. Finalmente el estudio se aproxima a la noción de objetivación estética y concretamente la noción de experimentación como (...) actividad crítica. (shrink)

The goal of this paper is to challenge the rather insouciant attitude that many investigators seem to adopt when they go about describing the items and events in their " visual fields". There are at least three distinct categories of interpretation of what these reports might mean, and only under one of those categories do those reports have anything resembling an observational character. The others demand substantive revisions in one's beliefs about what one sees. The ur-concept of a " visual (...) field" is that of the "sum of things seen", but one can interpret the latter in very different ways. The first is the "field of view", or the sum of physical things seen. The second is an array of visual impressions, whose spatial relations are distinct from those of physical phenomena in front of the eyes. The third is an intentional object: the world as it is represented visually. These three categories are described, and various locutions of vision science--such as "optic array", "retinocentric space", " visual geometry", "virtual object" and others--are analyzed and variously located within them. Finally, a recent argument purporting to necessitate the existence of a version two visual field is examined and shown wanting. (shrink)

Like many disciplines, moral philosophy is being subjected to critical scrutiny by feminist scholars. By applying a feminist critique of gender to the area of ethics, feminists pose the question, “Does gender make a difference?” or “Is ethics gendered?” Given that gender differences exist, it stands to reason that these differences might be institutionalized at the level of theory. Given also that different theories highlight different properties of a moral problem, theories can be evaluated according to how well, or how (...) poorly they account for gendered perspectives. Such gender differences need not be explained essentialistically, but may be explained as the result of different socialization strategies and the different social, political and economic standing of men and women. This discussion has seen the revival of the issue over whether ethical theory ought primarily to reflect care or justice, with the former reflecting a consequentialist approach with emphasis on concrete particulars and sentiment, and the latter reflecting a nonconsequentialist approach with emphasis on abstract universals and reason.

Michel Foucault aportó diferentes perspectivas sobre su propio trabajo. Así, en un principio, consideró sus libros como «cajas de herramientas». Más tarde, empezó a concebirlos como explosivos, para al final de su trayectoria intelectual abandonar esa perspectiva instrumental de sus trabajos y reconocer el ejercicio de la escritura como una praxis de transformación de sí mismo. Este estudio examina esas distintas perspectivas con el objeto de aportar un criterio a la hora de evaluar los usos actuales del trabajo de Foucault.

As research involving gene editing continues to advance, we are headed in the direction of being able to modify the human germline. Should we reach a point where an argument can be made that the benefits of preventing unborn children and future generations from inheriting genetic conditions that cause tremendous suffering outweigh the risks associated with altering the human germline, the next step will be to design clinical trials using this technology in humans. These clinical trials will likely require careful (...) follow-up and monitoring of future generations born with altered genes. This paper addresses some of the ethical issues raised by intergenerational monitoring and sets out to show that these issues can be avoided with careful consideration and clinical trial design.

University of Connecticut Storrs, CT 06279-2054. Recent versions of objectivism can reply to the argument from metamers. The deeper rift between subjectivists and objectivists lies in the question of how to explain the structure of qualitative similarities among the colors. Subjectivism grounded in this fashion can answer the circularity objection raised by Dedrick. It endorses skepticism about the claim that there is some one property of objects that it is the function of color vision to detect. Color vision may enable (...) us to detect differences in spectral composition without granting us the capacity to detect identities. (shrink)

Consequentialist theories that directly assess multiple focal points face an important objection: that one right option may conflict with another. Robert Adams raises an instance of this objection regarding the possibility that the right act conflicts with the right motives. Whereas only partial responses have previously been given, assuming particular views of the relation between motives and acts, an exhaustive treatment is in order. Either motives psychologically determine acts, or they do not – and I defend direct consequentialism on each (...) assumption. Crucially, if motives determine acts, this may be compatible with the ability to act otherwise, but there remains a defense for consequentialism even on these assumptions. What clears consequentialism of conflict is not necessarily that the apparently right act is unavailable, but rather that its outcome is suboptimal once we account for necessary motives. Even if the agent remains free to perform the act, the act costs too much. (shrink)

If one examines the sky at sunset on a clear night, one seems to see a continuum of colors from reds, oranges and yellows to a deep blue-black. Between any two colored points in the sky there seem to be other colored points. Furthermore, the changes in color across the sky appear to be continuous. Although the colors at the zenith and the horizon are obviously distinct, nowhere in the sky can one see any color borders, and every sufficiently small (...) region of the sky is made up of regions that all seem to be of the same color.

Suppose we admit for the sake of argument that "folk" explanations of human behavior--explanations in terms of beliefs and desires--sometimes succeed. They sometimes enable us to understand and predict patterns of motion that otherwise would remain unintelligible and unanticipated. Is the only explanation for such success that folk psychology is a viable proto-scientific theory of human psychology? I shall describe an analysis which yields a negative answer to that question. It was suggested by an observation and an analogy, both of (...) which may initially seem remote from the topic at hand. (shrink)
