This paper presents a general computational treatment of how mammals are able to deal with visual objects and environments. The model tries to cover the entire range from behavior and phenomenological experience to detailed neural encodings in crude but computationally plausible reductive steps. The problems addressed include perceptual constancies, eye movements and the stable visual world, object descriptions, perceptual generalizations, and the representation of extrapersonal space.The entire development is based on an action-oriented notion of perception. The observer is assumed to (...) be continuously sampling the ambient light for information of current value. The central problem of vision is taken to be categorizing and locating objects in the environment. The critical step in this process is the linking of visual information to symbolic object descriptions; this is calledindexing, from the analogy of identifying a book from index terms. The system must also identifysituationsand use this knowledge to guide movement and other actions in the environment. The treatment focuses on the different representations of information used in the visual system.The four representational frames capture information in the following forms: retinotopic, head-based, symbolic, and allocentric. The functional roles of the four frames, the communication among them, and their suggested neurophysiological realization constitute the core of the paper. The model is perforce crude, but appears to be consistent with all relevant findings. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 34.1 (2001) 21-37 [Access article in PDF] Conscience and the Concealments of Metaphor in Hobbes's Leviathan Karen S. Feldman Introduction Conscience is not a topic of terribly heated debate in Hobbes research. 1 Nevertheless, my claim in this article is that conscience in the Leviathan, which Hobbes poses as an example of the dangers of metaphor, is not merely an example of the dangers of (...) metaphor, but rather is the most dangerous metaphor, the metaphor that corrupts knowledge and thereby makes error and deception possible. Hobbes's brief account of conscience, which appears in the chapter of Leviathan on the ends of discourse, tells the story of the insinuation of metaphor into proper nomenclature; however, his example of the metaphorical use of the word conscience turns the story into one in which public knowledge itself is made private and thereby corrupted. Moreover, according to the story, private conscience is itself invented by means of a metaphor; it is in effect metaphorized into being. 2 With the emergence of private conscience, the potential of privatization expands from the privatization of the meaning of words to an entire private sphere of opinion. The metaphorical corruption of conscience invents a new understanding of knowledge as isolated from other witnesses, and the resultant privatization of truth lends itself to the corruption of that truth. Thus, whereas Hobbes characterizes the wrong use of names (of which metaphor is an instance) as a threat to accurate judgment and reason (L 22-23, 34, 161-62), as I will argue in the sections following, Hobbes's demand for the preservation of proper meaning in Leviathan corresponds to an anxiety regarding privacy and its peculiar potential for corrupting truth and knowledge. Hobbes's worries as to the dangers that metaphor poses to the stability of the commonwealth thereby converge with his worries about the dangers of conscience to the principle of public authority (cf. Strong 1993). [End Page 21] Hobbes's condemnations of conscience In Leviathan, conscience is condemned as a source of principles of human decision and action in a commonwealth. The problem with conscience as a principle of action is that it renders each individual inventor of his own rules and judge of his own actions. In brief, individual conscience is incommensurable with the public authority that defines a commonwealth: Another doctrine repugnant to civil society, is, that whatsoever a man does against his conscience, is sin; and it dependeth on the presumption of making himself judge of good and evil. For a man's conscience, and his judgment is the same thing, and as the judgment, so also the conscience may be erroneous. Therefore, though he that is subject to no civil law, sinneth in all he does against his conscience, because he has no other rule to follow but his own reason; yet it is not so with him that lives in a commonwealth; because the law is the public conscience, by which he hath already undertaken to be guided. Otherwise in such diversity, as there is of private consciences, which are but private opinions, the commonwealth must needs be distracted, and no man dare to obey the sovereign power, further than it shall seem good in his own eyes. (L 311) In this account, conscience is not just inferior to civil law as a principle guiding action, but at odds with civil society and the good of the commonwealth. The fact that conscience is private renders it problematic for the commonwealth for several reasons: First, as privately invented, it may be erroneous. Likewise, because it is private, conscience does not possess any binding power outside the individual, private sphere. Each person may be bound by his own conscience, but insofar as consciences differ, standards of action differ, and this leads to the undermining and distraction of the commonwealth. Likewise, private consciences may be divergent from one another, and the conflicts in private judgment produce conflicting actions that disturb the peace of the commonwealth. This rule of privacy is, moreover, associated with primitive life and with the state of nature... (shrink)

Businesses and governments in postcolonial countries frame investments in wind energy as efforts to address climate change and sustainable development. However, when wind energy projects encroach on indigenous peoples’ lives and land, there is often a lack of recognition and participation of these peoples and an unequal distribution of cost and benefits of such projects toward them, which leads to opposition against wind energy projects and often triggers conflicts for justice. Worryingly, such conditions have repeatedly resulted in the assassination of (...) human rights defenders, which further inflames the conflict. Herein, I discuss these concepts based on a longitudinal study centered on a wind energy project in Oaxaca, Mexico, with the aim of exploring and understanding the conditions under which wind energy investments fail to respect current laws and norms, as well as the consequences of such negligence. My in-depth analysis of the actions of the government, businesses, and indigenous peoples revealed a phenomenon that is less discussed in environmental justice research: the gradual and continuous transformation of indigenous peoples’ norms and behaviors away from their traditional economic and cultural livelihoods. This phenomenon helps to extend the conceptual understanding of environmental justice with regard to social turbulence, which is defined as the unpredictable behavior of political and social systems in contexts in which existing laws, regulations, and norms regarding environmental justice are not observed. The concept of social turbulence of environmental justice helps to explain how indigenous peoples sacrifice their territories, norms, and traditions to a technical solution to climate change and sustainable development.

Abrevando de la filosofía de la mente y de la ética filosófica, el perceptualismo moral argumenta que podemos tener experiencias perceptuales de propiedades morales, como “bueno” o “malo”, de la misma forma en que tenemos experiencias perceptuales de colores y formas. Es decir: el perceptualismo moral argumenta que podemos, literal, directa y simplemente ver la maldad, por ejemplo. A pesar de su amplio campo de estudio, estas perspectivas se han topado con objeciones formidables, como la objeción de las apariencias o (...) las críticas de corte humeano, para las cuales no se han dado respuestas satisfactorias. Este texto se propone sostener que gran parte de los problemas a los que se enfrenta el perceptualismo moral son producto de una vaga caracterización de las propiedades morales a las que pretendidamente se aplica la percepción, y postular un tipo de propiedad alternativa que pueda ser, al mismo tiempo, moralmente relevante y aprehensible por la experiencia perceptual. Para ello, se van a postular las llamadas propiedades de persona como opción alternativa, y se fundamentará su valor ético y su pertinencia para el perceptualismo moral mediante la noción de superveniencia ética. Se destacará que esta ruta merece ser explorada en virtud de su potencial para superar las críticas usuales que se le oponen al perceptualismo moral. (shrink)

A partir de una lectura crítica de El marxismo como moral, obra clásica de José Luis López Aranguren, éste artículo trata de interrogarse acerca de los fundamentos normativos y morales del marxismo. A lo largo del texto se proponen diversas líneas temáticas para profundizar en la dimensión ética del pensamiento de Karl Marx y la tradición marxista, tratando de liberar, al mismo tiempo, su proyecto intelectual y político de diversos tópicos vinculados a su recepción tradicional. El ámbito ético aparecerá como (...) espacio de mediación entre el conocimiento y la realidad, revelándose como fundamental para el marxismo desde un punto de vista praxeológico. Al final del artículo se dialoga críticamente con algunas posiciones éticas en el marco del marxismo contemporáneo. (shrink)

Desde un enfoque estructural e interdisciplinario, el artículo ofrece un pano-rama de uno de los fenómenos filosóficos más relevantes en América Latina: la Filosofía de la Liberación, enfatizando especialmente los momentos emblemáticos de su génesis y la necesidad de revaluar su potencial crítico en la sociedad contemporánea. La estructura temática del texto expone: a) un acercamiento a la definición del término Filosofía de la Liberación; b) un perfil de las principales características de este filosofar con-cretamente en su etapa inicial; c) (...) una reflexión sobre el paradigma neoliberal predominante; d) y diversos aportes de este filosofar ante los desafíos contemporáneos, que le brindan la oportunidad de redimensionar sus posibilidades críticas, a favor de los pobres, grupos oprimi-dos, pueblos periféricos o excluidos de los beneficios del sistema socio-económico y político vigente. El artículo brinda un repertorio del tema sin pretender lógicamente agotarlo, con el fin de indagar sobre la composición de la Filosofía de la Liberación, la diversidad de su desarrollo y al mismo tiempo sobre su importancia o vigencia en la actualidad.

Por la encrucijada que la figura de Søren Kierkegaard supone en la historia del pensamiento, siendo comúnmente considerado como gozne entre el idealismo y las filosofías de la existencia, entre la creencia en un espíritu objetivo y la reivindicación subjetivista que halla acomodo en el agitado siglo XX, parecería obligado identificar y aislar la cuestión propiamente filosófica, en el seno de una producción tan peculiar como la suya. Una producción abundante en incógnitas, pistas falsas y autores ficticios, con preocupaciones que (...) pertenecen a ámbitos contrastados, de la estética a la teología. Por su problematicidad inherente, el concepto de ambigüedad -que él mismo tematizó- puede entenderse clave en la aproximación crítica a su obra, como verdadero “contra-concepto”. (shrink)

Fred Feldman's fascinating new book sets out to defend hedonism as a theory about the Good Life. He tries to show that, when carefully and charitably interpreted, certain forms of hedonism yield plausible evaluations of human lives. Feldman begins by explaining the question about the Good Life. As he understands it, the question is not about the morally good life or about the beneficial life. Rather, the question concerns the general features of the life that is good in (...) itself for the one who lives it. Hedonism says (roughly) that the Good Life is the pleasant life. After showing that received formulations of hedonism are often confused or incoherent, Feldman presents a simple, clear, coherent form of sensory hedonism that provides a starting point for discussion. He then presents a catalogue of classic objections to hedonism, coming from sources as diverse as Plato, Aristotle, Brentano, Ross, Moore, Rawls, Kagan, Nozick, Brandt, and others. One of Feldman's central themes is that there is an important distinction between the forms of hedonism that emphasize sensory pleasure and those that emphasize attitudinal pleasure. Feldman formulates several kinds of hedonism based on the idea that attitudinal pleasure is the Good. He claims that attitudinal forms of hedonism - which have often been ignored in the literature -- are worthy of more careful attention. Another main theme of the book is the plasticity of hedonism. Hedonism comes in many forms. Attitudinal hedonism is especially receptive to variations and modifications. Feldman illustrates this plasticity by formulating several variants of attitudinal hedonism and showing how they evade some of the objections. He also shows how it is possible to develop forms of hedonism that are equivalent to the allegedly anti-hedonistic theory of G. E. Moore and the Aristotelian theory according to which the Good Life is the life of virtue, or flourishing. He also formulates hedonisms relevantly like the ones defended by Aristippus and Mill. Feldman argues that a carefully developed form of attitudinal hedonism is not refuted by objections concerning 'the shape of a life'. He also defends the claim that all of the alleged forms of hedonism discussed in the book genuinely deserve to be called 'hedonism'. Finally, after dealing with the last of the objections, he gives a sketch of his hedonistic vision of the Good Life. (shrink)

My conclusion will be that, more often than we might have thought, suspension of judgment is the epistemically proper attitude. It follows that in such cases we lack reasonable belief and so, at least on standard conceptions, knowledge. This is a kind of contingent real-world skepticism that has not received the attention it deserves. I hope that this paper will help to bring this issue to life.

Within the context of service inquiries, and the specialized inferential logic associated with the particularized activities there is a gap in the orientations of customers and service representatives. Specifically, one problem that arises in customer service encounters is that customers and service representatives appear to arrive at different understandings of what constitutes a relevant response to a service inquiry. By examining one type of customer service context, calls to an electronic repair facility, this article offers a conversation analytic account of (...) how customers use formulations to collaboratively achieve a mutually agreed upon answer to their service inquiry and close the gap in the underlying logics that emerge in these calls.

La caracterización de la ética postulada por Foucault en sus últimas investigaciones choca con la concepción del sujeto de sus primeros escritos, donde este se presenta como el paciente de las diversas presiones institucionales que le dan forma.

Para ello, se esbozarán las particularidades de la ética en Foucault para luego perfilar las oposiciones que esta encuentra en las regulaciones del campo de las relaciones de poder. A (...) través de esta indagación, se buscará dar respuesta a la pregunta de si es posible la vida ética en la filosofía foucaultiana. (shrink)

Vasubandhu is perhaps the most influential figure in the history of Buddhist philosophy, yet the very breadth of his contribution across many schools and traditions has led to a fragmentation of his works, as interpreters have tended to read them through the lens of narrow scholastic perspectives, finding little continuity or coherence. Some modern scholars, doubtful that anyone could have held such varied views, have gone so far as to divide Vasubandhu himself into two distinct philosophers, with two different and (...) irreconcilable views. In his recent book, Paving the Great Way: Vasubandhu’s Unifying Buddhist Philosophy, Jonathan Gold offers for the first time a unified picture of Vasubandhu, extracting the driving... (shrink)

When citizens are pulled over by police for traffic violations, they often volunteer accounts for their driving conduct. These accounts convey important character qualities about the citizen, as well as exigencies that motivate officer response. We use the method of conversation analysis to show that where a citizen positions an account in the course of an encounter is subject to different interactional-organizational constraints, which in turn afford citizens different resources for self-presentation. We also show that officers are sensitive to citizens’ (...) accounts and respond to them in differentiated ways. In addition to being a resource for self-presentation, citizens’ volunteered accounts are a resource for motivating and shaping police action. (shrink)

Evidentialism is a view about the conditions under which a person is epistemically justified in having a particular doxastic attitude toward a proposition. Evidentialism holds that the justified attitudes are determined entirely by the person's evidence. This is the traditional view of justification. It is now widely opposed. The essays included in this volume develop and defend the tradition.Evidentialism has many assets. In addition to providing an intuitively plausible account of epistemic justification, it helps to resolve the problem of the (...) criterion, helps to disentangle epistemic and ethical evaluations, and illuminates the relationship between epistemic evaluations of beliefs and the evaluation of the methods used to form beliefs. These issues are all addressed in the essays presented here. External world skepticism poses the classic problem for an epistemological theory. The final essay in this volume argues that evidentialism is uniquely well qualified to make sense of skepticism and to respond to its challenge.Evidentialism is a version of epistemic internalism. Recent epistemology has included many attacks on internalism and has seen the development of numerous externalist theories. The essays included here respond to those attacks and raise objections to externalist theories, especially the principal rival, reliabilism. Internalism generally has been criticized for having unacceptable deontological implications, for failing to connect epistemic justification to truth, and for failing to provide an adequate account of what makes basic beliefs justified. Each of these charges is answered in these essays. The collection includes two previously unpublished essays and new afterwords to five of the reprinted essays; it will be the definitive resource on evidentialism for all epistemologists. (shrink)

Evidentialism is the thesis that a person is justified in believing a proposition iff the person's evidence on balance supports that proposition. In discussing epistemological issues associated with disagreements among epistemic peers, some philosophers have endorsed principles that seem to run contrary to evidentialism, specifying how one should revise one's beliefs in light of disagreement. In this paper, I examine the connection between evidentialism and these principles. I argue that the puzzles about disagreement provide no reason to abandon evidentialism and (...) that there are no true general principles about justified responses to disagreement other than the general evidentialist principle. I then argue that the puzzles about disagreement are primarily puzzles about the evidential impact of higher - order evidence – evidence about the significance or existence of ordinary, or first- order, evidence. I conclude by arguing that such higher - order evidence can often have a profound effect on the justification of first- order beliefs. (shrink)
