Purely parallel neural networks can model object recognition in brief displays – the same conditions under which illusory conjunctions have been demonstrated empirically. Correcting errors of illusory conjunction is the “tag-assignment” problem for a purely parallel processor: the problem of assigning a spatial tag to nonspatial features, feature combinations, and objects. This problem must be solved to model human object recognition over a longer time scale. Our model simulates both the parallel processes that may underlie illusory conjunctions and the serial (...) processes that may solve the tag-assignment problem in normal perception. One component of the model extracts pooled features and another provides attentional tags that correct illusory conjunctions. Our approach addresses two questions: How can objects be identified from simultaneously attended features in a parallel, distributed representation? How can the spatial selectional requirements of such an attentional process be met by a separation of pathways for spatial and nonspatial processing? Our analysis of these questions yields a neurally plausible simulation of tag assignment based on synchronizing feature processing activity in a spatial focus of attention. (shrink)

Although "the Socratic method" is commonly understood as a style of pedagogy involving cross-questioning between teacher and student, there has long been debate among scholars of ancient philosophy about how this method as attributed to Socrates should be defined or, indeed, whether Socrates can be said to have used any single, uniform method at all distinctive to his way of philosophizing. This volume brings together essays by classicists and philosophers examining this controversy anew. The point of departure for many of (...) those engaged in the debate has been the identification of Socratic method with "the elenchus" as a technique of logical argumentation aimed at refuting an interlocutor, which Gregory Vlastos highlighted in an influential article in 1983. The essays in this volume look again at many of the issues to which Vlastos drew attention but also seek to broaden the discussion well beyond the limits of his formulation. Some contributors question the suitability of the elenchus as a general description of how Socrates engages his interlocutors; others trace the historical origins of the kinds of argumentation Socrates employs; others explore methods in addition to the elenchus that Socrates uses; several propose new ways of thinking about Socratic practices. Eight essays focus on specific dialogues, each examining why Plato has Socrates use the particular methods he does in the context defined by the dialogue. Overall, representing a wide range of approaches in Platonic scholarship, the volume aims to enliven and reorient the debate over Socratic method so as to set a new agenda for future research. Contributors are Hayden W. Ausland, Hugh H. Benson, Thomas C. Brickhouse, Michelle Carpenter, John M. Carvalho, Lloyd P. Gerson, Francisco J. Gonzalez, James H. Lesher, Mark McPherran, Ronald M. Polansky, Gerald A. Press, François Renaud, and W. Thomas Schmid, Nicholas D. Smith, P. Christopher Smith, Harold Tarrant, Joanne B. Waugh, and Charles M. Young. (shrink)

Like most aestheticians today I begin by firmly separating the concept of art from the concept of the aesthetic; unlike them, I conclude by reuniting these concepts in the thesis that the function of art is to promote the aesthetic. I understand the existence of artworks and of artists to be “institutional facts” (though the institution of art is an informal one, not to be confused with formal institutions to which it has given rise, such as museums, academies, etc.), while (...) I take “aesthetic situations,” involving appreciators and objects made, at least in part, to be appreciated, to constitute something approaching a natural kind. Rather than dealing directly with the concept of a function I argue for three theses closely related to the idea that the function of art is aesthetic: that art is better than any other institution at promoting the aesthetic; that art is better at promoting the aesthetic than it is at doing anything else; and that art was intended by its instituters to promote the aesthetic.

This article reports the findings from a study that investigates the relationship between ethical climates and police whistle-blowing on five forms of misconduct in the State of Georgia. The results indicate that a friendship or team climate generally explains willingness to blow the whistle, but not the actual frequency of blowing the whistle. Instead, supervisory status, a control variable investigated in previous studies, is the most consistent predictor of both willingness to blow the whistle and frequency of blowing the whistle. (...) Contrary to popular belief, the results also generally indicate that police are more inclined than civilian employees to blow the whistle in Georgia - in other words, they are less inclined to maintain a code of silence.

Attention only "recently"--i.e. in the eighteenth century--achieved chapter status in psychology textbooks in which psychology is conceived as a natural science. This report first sets this entrance, by sketching the historical contexts in which psychology has been considered to be a natural science. It then traces the construction of phenomenological descriptions of attention from antiquity to the seventeenth century, noting various aspects of attention that were marked for discussion by Aristotle, Lucretius, Augustine, and Descartes. The chapter goes on to compare (...) selected theoretical and empirical developments in the study of attention over three time slices: mid eighteenth century (C. Wolff, C. Bonnet, J. F. Abel), turn of the twentieth century (E. B. Titchener), and late twentieth century. Significant descriptive, theoretical, and empirical continuity emerges when these developments are considered in the large. This continuity is open to several interpretations, including the view that attention research shows long-term convergence because it is conditioned by the basic structure of attention as a natural phenomenon, and the less optimistic view that theory making in at least this area of psychology has been remarkably conservative when considered under large grain resolution, consisting in the reshuffling of a few core ideas.

_The Children of Light and the Children of Darkness_, first published in 1944, is considered one of the most profound and relevant works by the influential theologian Reinhold Niebuhr, and certainly the fullest statement of his political philosophy. Written and first read during the prolonged, tragic world war between totalitarian and democratic forces, Niebuhr’s book took up the timely question of how democracy as a political system could best be defended. Most proponents of democracy, Niebuhr claimed, were “children of light,” (...) who had optimistic but naïve ideas about how society could be rid of evil and governed by enlightened reason. They needed, he believed, to absorb some of the wisdom and strength of the “children of darkness,” whose ruthless cynicism and corrupt, anti-democratic politics should otherwise be repudiated. He argued for a prudent, liberal understanding of human society that took the measure of every group’s self-interest and was chastened by a realistic understanding of the limits of power. It is in the foreword to this book that he wrote, “Man’s capacity for justice makes democracy possible; but man’s inclination to injustice makes democracy necessary.” This edition includes a new introduction by the theologian and Niebuhr scholar Gary Dorrien in which he elucidates the work’s significance and places it firmly into the arc of Niebuhr’s career.

Analytic philosophy arose in the early decades of the twentieth century, with Bertrand Russell and G. E. Moore leading the way. Although some accounts emphasize the role of logic and language in the origin of analytic philosophy, of equal importance is the theme of perception, sense data, and knowledge, which dominated systematic philosophical discussion in the first two decades of the twentieth century in both Britain and America. This chapter examines work on perception and sense data as well as the (...) external world in the analytic tradition in the first half of the twentieth century. After sketching the situation before and just after 1900, it turns to Moore, Russell, and their interlocutors in the teens and twenties, addresses the American scene, looks to subsequent developments in the 1930s and beyond, and finally considers the fates of sense data and the ‘given’ and of the topic of perception more generally.

_A lively and highly readable commentary on one of Plato’s most beloved dialogues._.

The critical literary world has spent a wealth of thought and words on the question of Hawthorne himself: Where does he stand in his works? In history? In literary tradition? In this major new study, G. R. Thompson recasts the "Hawthorne question" to show how authorial presence in the writer's works is as much a matter of art as the writing itself. The Hawthorne who emerges from this masterful analysis is not, as has been supposed, identical to the provincial narrator (...) of his early tales; instead he is revealed to be the skillful manipulator of that narrative voice, an author at an ironic distance from the tales he tells. By focusing on the provincial tales as they were originally conceived--as a narrative cycle--Thompson is able to recover intertextual references that reveal Hawthorne's preoccupation with framing strategies and variations on authorial presence. The author shows how Hawthorne deliberately constructs sentimental narratives, only to deconstruct them. Thompson's analysis provides a new aesthetic context for understanding the whole shape of Hawthorne's career as well as the narrative, ethical, and historical issues within individual works. Revisionary in its view of one of America's greatest authors, The Art of Authorial Presence also offers invaluable insight into the problems of narratology and historiography, ethics and psychology, romanticism and idealism, and the cultural myths of America.

This chapter reconsiders the notion of perceptual constancy from the ground up. It distinguishes the phenomenology of perceptual constancy and stability from a functional characterization of perception as aiming at full constancy. Drawing on this distinction, we can attend to the phenomenology of constancy itself, and ask to what extent human perceivers attain constancy, as usually defined. Within this phenomenology, I distinguish phenomenal presentations of spatial features and color properties from categorizations, conceptualizations, and judgments that underlie verbal or other responses (...) to those presentations. Although phenomenal presentation and categorization commonly co-occur, they are distinct aspects of experience. After reviewing several standard descriptions of constancy, I present laboratory findings and my own phenomenological descriptions by way of confirming that, although perception "tends toward" constancy, human perceivers do not usually attain full constancy for either spatial or chromatic properties (as many investigators acknowledge). For spatial perception, I find that the phenomenology has been systematically misdescribed, and I offer a more adequate description of the phenomenology of everyday spatial perception. However, my greatest quarrel with previous theory concerns the functional aim of the constancies. I argue not only that perception does not achieve full constancy but that we should not characterize it as aiming for full constancy. Rather, perception seeks a stability of representation suitable for guiding our actions and which can also, as needed, enable us to classify and re-identify objects by phenomenally presented properties such as shape, size, or color. Further, I argue that theorists should not confuse these classifications with the qualitative character of phenomenal experience. My arguments underscore the need to distinguish phenomenal representation (better, "presentation") from conceptual categorization, and to distinguish perceptual presentations from subsequent processes that are involved in responding to them.

Descartes set for himself the ambitious program of accounting for the functions of the Aristotelian vegetative and sensitive souls without invoking souls or the faculties or powers of souls in his explanations. He rejects the notion that the soul is hylomorphically present in the organs of the body so as to carry out vital and sensory functions. Rather, the body’s organs operate in a purely mechanical fashion. That is what is involved in “mechanizing” these phenomena. The role of the soul (...) is restricted to properly mental functions: to the conscious aspects of sensations and other mental operations; to intellectual acts; and to acts of volition. In effect, soul becomes mind. In order to understand the extent of Descartes’ ambition, this chapter first considers more fully the functions attributed to the soul or to the vital faculties in the Aristotelian and Galenic traditions, and especially the functions of the sensitive soul or power. It draws attention to the cognitive aspects of these functions, beyond the mere operation of the external senses. Then it turns to Descartes’ mechanistic explanations for these cognitive functions. Finally, it situates Descartes’ new mechanistic psychology within the larger context of his novel anthropology, or theory of the human being. (shrink)

The view that a possible world is an existing abstract object implies that all nonexistent possible individuals have a principle of individuation in terms of existing objects, properties, and relations. However, some individuals of this kind are totally out of this world both in the subjective sense that nobody in this world can pick them out, and in the ontological sense that they would neither be created by assembling or arranging existing bits of matter nor otherwise be generated by existing (...) items. The only acceptable principle of individuation for such nonexistent possibles is that they are individuated by their unexemplified haecceities. (shrink)

ABSTRACTThis paper examines the ontological status of individual substances; intuitive examples of such entities include particles and living organisms. My aim is to assess the ontological status of individual substances in the light of arguments for an ontology of [concrete] facts, often called states of affairs. Advocates of a fact ontology have argued that these factive entities are the ontologically fundamental beings. I will address the salient question of whether individual substances are reducible to, or eliminable in favor of, facts. (...) I will further address the question of whether individual substances, even if not reducible to facts, are nonetheless ontologically dependent upon facts in a way that undercuts the claim that some individual substances are ontologically fundamental. Finally, I will argue that a persuasive case for the claim that facts are what is ontologically fundamental has yet to be made. (shrink)

This chapter compares rationalist theories of sense perception to previously held theories of perception (especially of vision) and examines rationalist accounts of sensory qualities and sensory representation, of the role of the sense-based passions in guiding behavior, of the epistemological benefits and dangers of sense perception, and of mind–body relations. Each section begins with Descartes, the first major rationalist of the seventeenth century. The other major rationalists, Malebranche, Spinoza, and Leibniz, and also lesser known figures such as Pierre Regis, Jacques (...) Rohault, and Antoine Le Grand, were well acquainted with Descartes' work. Indeed, the first three were each deeply influenced by Descartes in their early years before developing their own philosophical systems, and the latter three were all advocates of Descartes' philosophy (perhaps with slight revision). Each of the major rationalists, while sharing some positions in common, developed a distinctive metaphysics of perception and of the mind–body relation. Earlier sections chart these differences and a final section sums up common features and touches on the continuing significance of their views. (shrink)
