L'importance de l'analyse psychologique dans ce que l'on pourrait appeler, à la suite de George Briscoe Kerferd, « le mouvement sophistique », n'est pas en soi une découverte. De nombreuses études se sont en effet attachées à en souligner la portée, notamment dans ses rapports avec l'art rhétorique et son application pratique dans le cadre de la πόλις athénienne du Ve siècle où la parole — sous forme d'ἀγών, de débat contradictoire à l'assemblée ou au tribunal — (...) prévalait sur tous les autres instruments de pouvoir, violence et contrainte physique notamment. Dans un monde où « l’art politique, pour l'essentiel, maniement du langage », selon les mots de Jean-Pierre Vernant, analyser les mécanismes du logos, en connaître les règles, permettait de se rendre maître en persuasion, de posséder un instrument privilégié de victoire. Néanmoins, en marge de cet intérêt manifeste pour l'analyse du pouvoir du λόγος dans le corpus sophistique, on ne trouve, de manière assez paradoxale, qu'un nombre très limité de travaux s'attachant à questionner le sens, le statut et, in fine, la légitimité d'une « psychologie » au sens plein du terme. Et pourtant, la question se pose : peut-on parler d'une psychologie sophistique ou faut-il considérer que pour ces penseurs la ψυχή se donnait comme un état de fait dont il suffisait de connaître empiriquement le mécanisme? Y a-t-il quelque chose en-deçà de la psychagogie chez les sophistes? Dans cet article, nous tenterons de montrer qu’il est possible de voir en Alcidamas, disciple de Gorgias et auteur du Sur ceux qui composent des discours par écrit ou Sur les Sophistes, un éloge paradoxal, puisqu’écrit, de l’improvisation, un penseur de la ψυχή et non plus seulement de la potentialité psychagogique du λόγος. En effet, le développement d'une réflexion riche et complexe sur l’organisation logique et syntactique du discours d’une part, et sur l'âme et ses opérateurs d’autre part – réflexion qui conduit Alcidamas à réévaluer les modalités de relation entre l'orateur et son auditoire — permet de mettre en évidence une redéfinition (bien qu'en filigrane) de l'art rhétorique qui, ne pouvant plus dès lors reposer sur une revendication du pouvoir de la persuasion a maxima, devra accorder à la notion de vraisemblance une place centrale.

Action is a means of acquiring perceptual information about the environment. Turning around, for example, alters your spatial relations to surrounding objects and, hence, which of their properties you visually perceive. Moving your hand over an object’s surface enables you to feel its shape, temperature, and texture. Sniffing and walking around a room enables you to track down the source of an unpleasant smell. Active or passive movements of the body can also generate useful sources of perceptual information (Gibson 1966, (...) 1979). The pattern of optic flow in the retinal image produced by forward locomotion, for example, contains information about the direction in which you are heading, while motion parallax is a “cue” used by the visual system to estimate the relative distances of objects in your field of view. In these uncontroversial ways and others, perception is instrumentally dependent on action. According to an explanatory framework that Susan Hurley (1998) dubs the “Input-Output Picture”, the dependence of perception on action is purely instrumental: "Movement can alter sensory inputs and so result in different perceptions… changes in output are merely a means to changes in input, on which perception depends directly" (1998: 342). -/- The action-based theories of perception, reviewed in this entry, challenge the Input-Output Picture. They maintain that perception can also depend in a noninstrumental or constitutive way on action (or, more generally, on capacities for object-directed motor control). This position has taken many different forms in the history of philosophy and psychology. Most action-based theories of perception in the last 300 years, however, have looked to action in order to explain how vision, in particular, acquires either all or some of its spatial representational content. Accordingly, these are the theories on which we shall focus here. -/- We begin in Section 1 by discussing George Berkeley’s Towards a New Theory of Vision (1709), the historical locus classicus of action-based theories of perception, and one of the most influential texts on vision ever written. Berkeley argues that the basic or “proper” deliverance of vision is not an arrangement of voluminous objects in three-dimensional space, but rather a two-dimensional manifold of light and color. We then turn to a discussion of Lotze, Helmholtz, and the local sign doctrine. The “local signs” were felt cues for the mind to know what sort of spatial content to imbue visual experience with. For Lotze, these cues were “inflowing” kinaesthetic feelings that result from actually moving the eyes, while, for Helmholtz, they were “outflowing” motor commands sent to move the eyes. -/- In Section 2, we discuss sensorimotor contingency theories, which became prominent in the 20thcentury. These views maintain that an ability to predict the sensory consequences of self-initiated actions is necessary for perception. Among the motivations for this family of theories is the problem of visual direction constancy—why do objects appear to be stationary even though the locations on the retina to which they reflect light change with every eye movement?—as well as experiments on adaptation to optical rearrangement devices (ORDs) and sensory substitution. -/- Section 3 examines two other important 20th century theories. According to what we shall call the motor component theory, efference copies generated in the oculomotor system and/or proprioceptive feedback from eye-movements are used together with incoming sensory inputs to determine the spatial attributes of perceived objects. Efferent readiness theories, by contrast, look to the particular ways in which perceptual states prepare the observer to move and act in relation to the environment. The modest readiness theory, as we shall call it, claims that the way an object’s spatial attributes are represented in visual experience can be modulated by one or another form of covert action planning. The bold readiness theory argues for the stronger claim that perception just is covert readiness for action. -/- In Section 4, we move to the disposition theory, most influentially articulated by Gareth Evans (1982, 1985), but more recently defended by Rick Grush (2000, 2007). Evans’ theory is, at its core, very similar to the bold efferent readiness theory. There are some notable differences, though. Evans’ account is more finely articulated in some philosophical respects. It also does not posit a reduction of perception to behavioral dispositions, but rather posits that certain complicated relations between perceptual input and behavioral provide spatial content. Grush proposes a very specific theory that is like Evans’ in that it does not posit a reduction, but unlike Evans’ view, does not put behavioral dispositions and sensory input on an undifferentiated footing.

George Kerferd inicia seu livro fazendo um levantamento dos principais problemas que surgem quando tentamos compreender aquilo que foi “o movimento sofista”. Além de não possuirmos qualquer obra completa de algum desses pensadores, a tradição nos deixou um legado profundamente pejorativo que acabou por ser aceito e propagado nos manuais da história da filosofia através dos tempos modernos e contemporâneos. Isso se dá, sobretudo, pelo fato de conhecermo-los apenas por intermédio dos escritos daqueles o retratavam de maneira hostil. (...) A saber, os diálogos de Platão e os tratados esotéricos de Aristóteles formam as principais obras que engendraram a visão negativa desse movimento. (shrink)

Poverty is a complex, embodied reality comprising the existential, social, material, and spiritual. This paper draws from liberation theologies from North and South America, defining poverty as a religio-historical realidad. Martin Luther King Jr. observed a disembodied spirituality in many American churches who remained apathetic or antagonistic during the Civil Rights Movement. Conversely, James Cone reversed the issue by providing a theological system which utilizes hyper-materialistic presuppositions. By examining the broader Liberation tradition, a more robust theological definition of poverty can (...) be construed. Systems of poverty are systems of death, whereas enrichment are processes of life. Embodiment was used during colonial Christianity as a market identity in order to justify conquest. Liberation theologians reclaim creatureliness in their fight against poverty, and fight for restored identity. Each section of the paper addresses major trajectories within the broad Liberation tradition. North American liberationists analyze poverty from the perspective of racial oppression enforced through visible bodies. South American liberationists created a systematic, biblical definition of poverty while primarily addressing economic exploitation. Feminists addressed their male-dominated worlds addressing quality and quantity of life issues. Both North American and South American theologians agree that Christ identifies with the poor and understands their plight. In the end, Christ is understood as a liberator who is Lord over the material, spiritual, personal, and social. (shrink)

"We must turn to the Euthydemus if we are to understand both Plato's earlier and his more mature work. Thomas Chance's book is an indispensible tool for penetrating to the sources of Plato's thinking on the nature of philosophy. This is the most impressive treatment of the dialogue so far available to scholars, and the interpretations offered will surely be the starting point for all future discussions."--G. B. Kerferd, Emeritus, University of Manchester "A sensitive and well-informed study of an (...) important and much neglected dialogue."--R. E. Allen, Northwestern University "A sensitive and well-informed study of an important and much neglected dialogue."--R. E. Allen "Chance's book [will be] an indispensable tool for penetrating to the sources of Plato's thinking....

This paper is a critical discussion of the recent tendency to moralize various aspects of life that were previously viewed as private and discretionary. The paper takes as its starting point six recently unearthed moral prohibitions, and it examines the prospects for defending each as an extension of some familiar moral requirement. Its conclusion is not only that none of the extended prohibitions are defensible, but also that each impedes morality's function by limiting the ability of those whose lives it (...) governs to pursue their own aims as they see fit.

_Plato's Thought_ offers an excellent introduction to Plato, guiding the reader through Plato's Theory of Forms, and examining his views on art, education and statecraft. This edition includes an introduction, bibliographic essay, and bibliography by Donald Zeyl.

Black Bodies, White Gazes: The Continuing Significance of Race understands Black embodiment within the context of white hegemony within the context of a racist, anti-Black world. Yancy demonstrates that the Black body is a historically lived text on which whites have inscribed their projections which speak equally forcefully to whites' own self-conceptualizations.

In his response to my essay “Out of Control,” Neil Levy contests my claims that (1) we are often responsible for acts that we do not consciously choose to perform, and that (2) despite the absence of conscious choice, there remains a relevant sense in which these actions are within our control. In this reply to Levy, I concede that claim (2) is linguistically awkward but defend the thought that it expresses, and I clarify my defense of claim (1) by (...) distinguishing my position from attributionism.

In this study, George Rudebusch addresses whether Socrates was a hedonist--whether he believed pleasure to be the good. In attempting to locate Socrates' position on hedonism, Rudebusch examines the passages in Plato's early dialogues that are the most disputed on the topic. He maintains that Socrates identifies pleasant activity with virtuous activity, describing Socrates' hedonism as one of activity, not sensation. This analysis allows for Socrates to find both virtue and pleasure to be the good, thus solving the textual (...) puzzle and showing the power of Socratic argument in leading human beings toward the good.

The role of metaphysics in critique stands as a defining issue for the Frankfurt School theorists. Max Horkheimer himself claims that metaphysics serves as an instrument of domination, leading him to develop an interdisciplinary mate- rialism as a postmetaphysical alternative. Critics such as Georg Lohmann con- tend, however, that Horkheimer’s critique of instrumental reason is aporetic insofar as it undermines all metaphysical claims while implicitly making them. Since Horkheimer narrowly equates metaphysics with identity thinking, this article argues that his appeal (...) to nonidentity thinking as the foundation for critique is better understood as a form of antimetaphysics. This, however, leaves Horkheimer no better situated, since antimetaphysics remains a variant of metaphysics. While Horkheimer reproduces the techniques of domination he sought to avoid, this lapse into metaphysics warns of the difficult path that postmetaphysical thinking must navigate between the antipodes of metaphys- ical and antimetaphysical positions.
