We present a technique for the analysis of pattern formation by a class of models for the formation of ocular dominance stripes in the striate cortex of some mammals. The method, which employs the adiabatic approximation to derive a set of ordinary differential equations for patterning modes, has been successfully applied to reaction-diffusion models for striped patterns [1]. Models of ocular dominance stripes have been studied [2,3] by computation, or by linearization of the model equations. These techniques do (...) not provide a rationale for the origin of the stripes. We show here that stripe formation is a non-linear property of the models. Our analysis indicates that stripe selection is closely linked to a property in the dynamics of the models which arises from a symmetry between ipsilateral and contralateral synapses to the visual cortex of a given hemisphere.

In Selfless Cinema?, Sarah Cooper maps out the power relations of making, and viewing, documentaries in ethical terms. The ethics of filmmaking are often examined in largely legalistic terms, dominated by issues of consent, responsibility, and participantse(tm) or film-makerse(tm) rights, but Cooper approaches four representative French film-makers e" Jean Rouch, Chris Marker, Raymond Depardon, and Agns Varda e" in a far less juridical way, drawing on the ethical philosophy of Emmanuel Levinas. She argues that, in spite of Levinase(tm)s iconoclastic, anti-ocular (...) thinking, his concept of visage is richly applicable to film, and especially to documentary. (shrink)

No one before Platter and Kepler proposed retinal reception of an inverted visual image. The dominant tradition in visual theory, especially that of Alhazen and his Western followers, subordinated the intra-ocular geometry of visual rays to the requirement for an upright image and to preconceptions about the precise nature of the visual spirit and its part in vision. Henry of Langenstein and an anonymous glossator in the late Middle Ages proposed alternatives to Alhazen, including the suggestion of double inversion of (...) the image. Leonardo da Vinci was aware of both Alhazen's theory and Henry's contradiction, but perhaps not of the anonymous hypothesis of double inversion. Leonardo's visual ‘theory’ has more the character of a critique than of a theoretical alternative, and he did not transcend the medieval concept of visual spirit. (shrink)

How can the question of authority, the power and presence of the English, be posed in the interstices of a double inscription? I have no wish to replace an idealist myth—the metaphoric English book—with a historicist one—the colonialist project of English civility. Such a reductive reading would deny what is obvious, that the representation of colonial authority depends less on a universal symbol of English identity than on its productivity as a sign of difference. Yet in my use of “English” (...) there is a “transparency” of reference that registers a certain obvious presence: the Bible translated into Hindi, propagated by Dutch or native catechists, is still the English book; a Polish émigré, deeply influenced by Gustave Flaubert, writing about Africa, produces an English classic. What is there about such a process of visibility and recognition that never fails to be an authoritative acknowledgement without ceasing to be a “spacing between desire and fulfillment, between perpetuation and its recollection … [a] medium [which] has nothing to do with a center” ?This question demands a departure from Derrida’s objectives in “The Double Session”; a turning away from the vicissitudes of interpretation in the mimetic act of reading to the question of the effects of power, the inscription of strategies of individuation and domination in those “dividing practices” which construct the colonial space—a departure from Derrida which is also a return to those moments in his essay when he acknowledges the problematic of “presence” as a certain quality of discursive transparency which he describes as “the production of mere reality-effects” or “the effect of content” or as the problematic relation between the “medium of writing and the determination of each textual unit.” In the rich ruses and rebukes with which he shows up the “false appearance of the present,” Derrida fails to decipher the specific and determinate system of address that is signified by the “effect of content” . It is precisely such a strategy of address—the immediate presence of the English—that engages the questions of authority that I want to raise. When the ocular metaphors of presence refer to the process by which content is fixed as an “effect of the present,” we encounter not plenitude but the structured gaze of power whose objective is authority, whose “subjects” are historical.

Nikos K. Logothetis University of Manchester, Manchester, UK In binocular rivalry, the visual percept alternates stochastically between two dichoptically presented stimuli. It is established that both processes related to the eye of origin and binocular, stimulus-related processes account for these fluctuations in conscious perception. Here we studied how their relative contributions vary over time. We applied brief disruptions to rivalry displays, concurrent with an optional eye swap, at varying time intervals after one stimulus became visible (dominant). We found that early (...) in a dominance phase the dominant eye determined the percept by stabilizing its own contribution (regardless of the stimulus), with an additional yet weaker stabilizing contribution of the stimulus (regardless of the eye). Their stabilizing contributions declined in parallel with time so that late in a dominance phase the stimulus (and in some cases also the eye-based) contribution turned negative, favoring a perceptual (or ocular) switch. Our findings show that depending on the time, first processes related to the eye of origin and then those related to the stimulus can have a greater net influence on the stability of the conscious percept. Their co-varying change may be due to feedback from image- to eyeof-origin representations. (shrink)

Certain representations are bound in special ways to our sensory capacities; consider, for instance, pictures, sound recordings, and the various forms of mental sensory imagery. What do these representations have in common, and what makes them different from representations of other kinds? Dominic Gregory employs novel ideas on perceptual states and sensory perspectives to explain the special nature of the contents of distinctively sensory representations. The book contains extensive discussions of e.g. perceptual imagination, pictorial representation, and memories.

Dominic Scott compares the Republic and Nicomachean Ethics from a methodological perspective. He argues that Plato and Aristotle distinguish similar levels of argument in the defence of justice, and that they both follow the same approach: Plato because he thinks it will suffice, Aristotle because he thinks there is no need to go beyond it.

Paraconsistent responses to vagueness are often thought to represent a revision of logical theory that is too radical to be defensible. The paracomplete logic of supervaluationism, SpV, is not only taken to be more conservative but is also commonly said to 'preserve classical logic'. This chapter argues that this is wrong on both counts. The paraconsistent logic SbV, or subvaluationism, is no less conservative than SpV nor more so. In the end both logics offer equally compelling theoretical approaches to vagueness. (...) Each approach is also equally objectionable, with neither providing an adequate account of vagueness, but this criticism arises from a feature shared by each approach that is independent of their paracompleteness or paraconsistency per se. For all that has been said, a paraconsistent approach, and the associated recourse to truth-value gluts, remains a contender in accounting for vagueness. (shrink)

Ocular gene transfer clinical trials are raising hopes for blindness treatments and attracting media attention. News media provide an accessible health information source for patients and the public, but are often criticized for overemphasizing benefits and underplaying risks of novel biomedical interventions. Overly optimistic portrayals of unproven interventions may influence public and patient expectations; the latter may cause patients to downplay risks and over-emphasize benefits, with implications for informed consent for clinical trials. We analyze the news media communications landscape about (...) ocular gene transfer and make recommendations for improving communications between clinicians and potential trial participants in light of media coverage.

[David Charles] Aristotle, it appears, sometimes identifies well-being with one activity, sometimes with several, including ethical virtue. I argue that this appearance is misleading. In the Nicomachean Ethics, intellectual contemplation is the central case of human well-being, but is not identical with it. Ethically virtuous activity is included in human well-being because it is an analogue of intellectual contemplation. This structure allows Aristotle to hold that while ethically virtuous activity is valuable in its own right, the best life available for (...) humans is centred around, but not wholly constituted by, intellectual contemplation. /// [Dominic Scott] In Nicomachean Ethics X 7-8, Aristotle distinguishes two kinds of eudaimonia, primary and secondary. The first corresponds to contemplation, the second to activity in accordance with moral virtue and practical reason. My task in this paper is to elucidate this distinction. Like Charles, I interpret it as one between paradigm and derivative cases; unlike him, I explain it in terms of similarity, not analogy. Furthermore, once the underlying nature of the distinction is understood, we can reconcile the claim that paradigm eudaimonia consists just in contemplation with a passage in the first book requiring eudaimonia to involve all intrinsic goods.

Representational theories of mind cannot individuate the sense modalities in a principled manner. According to representationalism, the phenomenal character of experiences is determined by their contents. The usual objection is that inverted qualia are possible, so the phenomenal character of experiences may vary independently of their contents. But the objection is inconclusive. It raises difficult questions about the metaphysics of secondary qualities and it is difficult to see whether or not inverted qualia are possible. This paper proposes an alternative test (...) of representationalism. Do experiences in different sense modalities have the same phenomenal character when they share content? Psychological work on the perception of shape through vision and spatial hearing is discussed. This work shows that visual and auditory experiences differ in phenomenal character even in so far as they represent similar properties. This objection to representationalism does not invite questions about secondary qualities or depend on establishing metaphysical possibilities. (shrink)

Can love really be considered another form of technology? Dominic Pettman says it can - although not before carefully redefining technology as a cultural challenge to what we mean by the "human" in the information age. Using the writings of such important thinkers as Giorgio Agamben, Jean-LucNancy, and Bernard Stiegler as a springboard, Pettman explores the "techtonic" movements of contemporary culture, specifically in relation to the language of eros. Highly ritualized expressions of desire - love, in other words - always (...) reveal an era's attitude toward what it means to exist as a selfamong others. For Pettman, the articulation of love is a technique of belonging: a way of responding to the basic plurality of everyone's identity, a process that becomes increasingly complex as the forms of mediated communication, from cell phone and text messaging to the mass media, multiply andmesh together.Wresting the idea of love from the arthritic hands of Romanticism, Pettman demonstrates the ways in which this dynamic assemblage - "the stirrings of the soul" - have always been a matter of tools, devices, prosthetics, and media. Love is, after all, something we make. And, love, this book argues,is not eternal, but external. (shrink)

Philosophers have championed contextualist and relativist semantics for aesthetic discourse that attempt to explain faultless disagreement. However, both types of semantics do a good job explaining faultless disagreement. As a rule, more explananda assist in theory choice. This chapter proposes that three more facts need explaining. Aesthetic disputes revolve around objects, even as they express attitudes. They also extend into lengthy exchanges wherein reasons are offered and withdrawn. Finally, they play a role in the formation and regulation of aesthetic practices. (...) Different views about the point of aesthetic disputes interpret these three facts differently. One option has it that we use aesthetic disputes to align with peers who share the same preferences. This option is friendly to relativist semantics. The alternative states that we use aesthetic disputes to coordinate language and concepts to fit aesthetic genres. This option mandates contextualist semantics. The weight of evidence tilts towards contextualism. (shrink)

Dominic LaRochelle | : Les religions ne constituent pas des monolithes immuables et inchangés dans le temps. Elles évoluent au fil de l’histoire humaine, changent au gré des transformations culturelles et sociales des communautés dans lesquelles elles s’implantent, négocient avec les instances séculières et religieuses leur pertinence et leur droit d’exister ; bref, elles innovent constamment pour s’assurer une place dans un monde lui aussi en constant changement. Cet article propose deux outils pour analyser les innovations au sein des traditions (...) religieuses : les théories de la réception, inspirées des travaux de Hans Robert Jauss, et l’invention des traditions, inspirée du célèbre ouvrage d’Eric J. Hobsbawm et Terence O. Ranger. L’intérêt de l’utilisation de ces outils en histoire est qu’ils permettent, entre autres choses, de dépasser les oppositions classiques tradition/modernité et authenticité/innovation en analysant les religions du point de vue des ruptures et des transformations à l’intérieur de celles-ci. Ces outils seront appliqués à un cas particulier, celui de la réception et de la réinvention du taoïsme dans les sociétés occidentales au XXe siècle. Cette tradition religieuse chinoise vieille de plusieurs siècles a en effet été réinventée en Occident et transformée en une tradition spirituelle universelle répondant aux attentes des Occidentaux en matière de spiritualité contemporaine. | : Religions are not immutable monoliths that remain unchanged over time. They evolve over the course of human history ; changing according to the cultural and social transformations of the communities in which they are established and negotiating with secular and religious authorities for their relevance and right to exist. In short, they continually innovate to secure a place in a constantly changing world. This article proposes two tools to analyze innovations within religious traditions : reception theories, inspired by the works of Hans Robert Jauss, and the invention of tradition, inspired by the celebrated work of Eric J. Hobsbawm and Terence O. Ranger. The interest of using these tools in a historical approach is that they allow us, among other things, to overcome the traditional oppositions of tradition vs. modernity and authenticity vs. innovation by analyzing religions from a rupture and transformation point of view. These tools will be applied to a particular case, namely the reception and reinvention of Taoism in Western societies in the twentieth Century. This centuries-old Chinese religious tradition has been reinvented in the West and transformed into a universal spiritual tradition that meets the expectations of Westerners for contemporary spirituality.

In lieu of an abstract, here is a brief excerpt of the content:Autonomy, Experience, and TherapyDominic Murphy (bio)The contemporary philosophical idea of autonomy has a psychological implication, to wit, that there exists a comprehensive set of ideal competences, realized in our mind/brain, that enable a person to be self-governing. Autonomy is normally accorded individuals who enjoy a certain kind of psychological functioning and, perhaps, a certain sort of psychological history (Christman 1991). We think that autonomous individuals critically evaluate their life (...) and actions, endorse them as self-determined rather than imposed from without, and guide their own lives in accordance with the plans and values they have worked out for themselves. Such self-government has to depend on some psychological structures, but philosophers have tended to theorize about what these structures might be at a considerable distance from what the behavioral sciences can tell us. Anderson and Lux's paper is a welcome contribution to the growing literature that tries to connect issues in ethics with empirical considerations. This sort of methodological, as opposed to merely metaphysical, naturalism, is only just coming into vogue in ethics, even in moral psychology.1 Anderson and Lux are, as far as I am aware, the first people to reflect seriously on what we can learn about autonomy from clinical experience. Theirs is a very suggestive and fruitful paper that looks at real-life cases of loss of autonomy and tries to reach conclusions about what the deficits in performance tell us about the psychological preconditions of autonomy. Their paper also opens the way for an investigation into the precise neurologic and computational underpinnings of these capacities, which is essential if we are to get a serious moral psychology underway.I find little to quarrel with in the story that Anderson and Lux tell, but I will try to modify it slightly to bring out what I think is the important psychological point they make and explore some ramifications. I begin by claiming that they have scored a decisive point in favor of an external conception of autonomy. Second, I suggest that what Anderson and Lux have really put their finger on is less a requirement of accurate self-assessment than a requirement of sensitivity to feedback from the environment. I conclude by raising some of these issues about the relations between autonomy and assessments of psychological function when the deficit responsible is less amenable to clear cut neurologic identification.The External Perspective on AutonomyOne way of taking the paper (although this goes beyond anything that Anderson and Lux suggest) is that there is a smooth naturalistic picture of the cognitive basis of autonomy. When people have a normally functioning neurocomputational setup in their heads, we should assume that they are autonomous, and vice versa. However, autonomy cannot simply be identifiable with a mind that is working as some scientific theory says it should, because a mind that is [End Page 303] in that sense working correctly could, nonetheless, be directed by forces other than the agent. Servile or deluded individuals might endorse their lives even if those lives are the product of indoctrination, self-deception, or internalized oppression (Mackinnon 1997; Mele 1995). Normal mechanisms of belief fixation, for example, may not foster one's autonomy if the only context in which they are exercised is one in which many possible ways of life are simply unavailable for consideration, having been excluded from consideration by the dominant forces around one. We might, then, think of full autonomy as depending on relational rather than intrinsic properties. Perhaps autonomy requires a subject to have both normal psychological capacities and the right sort of environment in which to exercise them. I do not follow-up on this suggestion, but I mention it because it introduces two dimensions, within the subject and around the subject, where the externalist perspective on autonomy can get a grip. I discuss the former, but I do not mean to suggest that the latter is not important. A full account must deal with both. But even the psychological structures that foster autonomy cannot be identified with a mind working according to some scientific theory, as we shall see.Many writers on autonomy argue that we must recognize appropriate, objective constraints...

Wakefield's (2000) responses to our paper herein (Murphy and Woolfolk 2000) are not only unsuccessful, they force him into a position that leaves him unable to preserve any distinction between disorders and other problems. They also conflate distinct scientific concepts of function. Further, Wakefield fails to show that ascriptions of human dysfunction do not ineliminably involve values. -/- We suggest Wakefield is analyzing a concept that plays a role in commonsense thought and arguing that the task of science is to (...) identify the natural processes that accord with that commonsense concept. We argue that this represents an attempt to use conceptual analysis to legislate what should be acceptable science. We conclude that this constraint on science is unacceptable and that therefore Wakefield's overall position should be rejected. (shrink)

What you see can shape how you feel, and the route from seeing to feeling sometimes involves empathy – as you might empathize with a woman you see grieving the death of her child. But empathy also comes from what you see in pictures. Bellini's Pieta? is one among many paintings, drawings, prints, and photographs that evoke empathy – and are designed to do so. Going further, it seems that episodes of empathy triggered by pictures can help build up a (...) person's capacity for empathic response. Indeed, they do so by fortifying the link between seeing and empathy in a distinctive way. To establish this thesis, we need a broad conception of empathic response and also the right conception of what we see in pictures. (shrink)

Hypotheses in aesthetics should explain appreciative failure as well as appreciative success. They should state the general conditions under which people fail to understand and value works as works of art. This stricture is all the more important when the typical response to conceptual art is one of resistance. Some philosophers explain this by claiming that conceptual art violates traditional theories of art. Others say that it violates folk ontologies of art. In fact, the appreciative failure to which conceptual art (...) is prone is a consequence of the fact that it is not visual art, as it appears to be; rather it is an entirely new art form. Works in new art forms pose special challenges to appreciation. Identifying these challenges enriches theorizing about art. (shrink)

For centuries, philosophers have identified beauty with what brings pleasure.

Aesthetic appreciation involves background belief. While some appreciations are adequate when these beliefs are false, there is an important class of beliefs -- beliefs about the nature art work kinds -- whose truth is required for adequate appreciation. Photography is an interesting case, since many of our beliefs about it are false.

In Gaudium et Spes and Dignitatis Humanae the Second Vatican Council not only presents the dignity of the human person as the parting point for its moral teaching but also grounds human dignity in natural teleology. Natural teleology is the view that the good of any thing corresponds to, and so can be discerned from, the ends to which it is directed by its nature, both that end which is proper to it and those ends that it has as part (...) of a wider order. As official Church teachings, these documents refrain from providing a philosophical justification of their account of human dignity. The existence of natural teleology, however, is generally contested in modern philosophy. For this reason, grounding human dignity in natural teleology constitutes a questionable approach to the issue. Of all major Catholic theologians, Thomas Aquinas is arguably the one who provides the most developed philosophical resources for articulating these views on natural teleology and its connection with human dignity. This paper examines and assesses the way in which he grounds human dignity in natural teleology. In his view, we see that human beings are the principle part of the universe and that the other parts of the universe are ordered towards the good of human beings. After surveying his general justification of how a thing is ordered to particular ends in virtue of its nature, the paper considers his explanation of how each part of the universe assumes further ends within the universe as a whole, and his main set of arguments on how we perceive human dignity against the backdrop of the natural teleology of the universe.

Death and grief in the ancient world -- Predictions and disability in Rome.

This paper discusses the Victorian idea that sport builds character, which was one of the inspirations for the modern Olympic movement and remains central to policy debates on sport. The argument is that sport, even in the highly moralised context of ‘muscular Christianity’, failed in this character-forming role, and should not be seen as a source of moral regeneration. The paper argues that the tendency to over-moralise sport, like the commercialisation of sport, has the effect of diminishing the ‘play element’. (...) Recovering sport as play, it is argued, is essential to unlocking its potential to lift the spirit—if not to build character, as the muscular Christians believed. (shrink)

Pictures are valuable partly because they engage perception in distinctive ways. This chapter surveys recent accounts of depiction, of the distinctive content and phenomenology of our experiences of images, and of the artistic or aesthetic value that these experiences afford. Particular attention is paid to recent research on the relationship between seeing a flat image surface and having an experience as of the scene it represents.
