Evidence from functional neuroimaging of the human brain indicates that information about salient properties of an object¿such as what it looks like, how it moves, and how it is used¿is stored in sensory and motor systems active when that information was acquired. As a result, object concepts belonging to different categories like animals and tools are represented in partially distinct, sensory- and motor property-based neural networks. This suggests that object concepts are not explicitly represented, but rather emerge from weighted activity (...) within property-based brain regions. However, some property-based regions seem to show a categorical organization, thus providing evidence consistent with category-based, domain-specific formulations as well.Acronyms and DefinitionsBiological motion: motion of animate agents characterized by highly flexible, fully articulated motion vectors, in contrast to the rigid, unarticulated motion vectors associated with most tools.Category-specific disorder: a relatively greater impairment in retrieving information about members of one superordinate object category (e.g., animals) as compared with other categories following brain injury or diseaseIPS: intraparietal sulcusLO: lateral occipital cortexObject concept: memory representations of a class or category of objects.

The Liar paradox arises when we consider a sentence that says of itself that it is not true. If such self-referential sentences exist? and examples like?This sentence is not true? certainly suggest this?, then our logic and standard notion of truth allow to infer a contradiction: The Liar sentence is true and not true. What has gone wrong? Must we revise our notion of truth and our logic? Or can we dispel the common conviction that there are such self-referential sentences? (...) The present study explores the second path.0After comparing the Liar reasoning in formal and informal logic and showing that there are no Gödelian Liar sentences, the study moves on from the semantics of self-reference to the metaphysics of expressions and proposes a novel solution to the Liar paradox: Meaningful expressions are distinct from their syntactic bases and exist only relative to contexts. Detailed semantico-metaphysical arguments show that in this dynamic setting, an object can be referred to only after it has started to exist. Hence the circular reference needed in the Liar paradox cannot occur, after all. As this solution is contextualist, it evades the expressibility problems of other proposals. (shrink)

Argument and imagination are often interdependent. The Aesthetics of Argument is concerned with how this relationship may bear on argument's concern with truth, not just persuasion, and with the enhancement of understanding such interdependence may bring. The rationality of argument, conceived as the advancement of reasons for or against a claim, is not simply a matter of deductive validity. Whether arguments are relevant, have force, or look foolish cannot always be assessed in these terms. Martin Warner presents a series (...) of case studies which explore how analogy, metaphor, narrative, image, and symbol can be used in different ways to frame one domain in terms of another, and how criteria drawn from the study of imaginative literature may have a bearing on their truth-aptness.

Questions concerning the proof-theoretic strength of classical versus nonclassical theories of truth have received some attention recently. A particularly convenient case study concerns classical and nonclassical axiomatizations of fixed-point semantics. It is known that nonclassical axiomatizations in four- or three-valued logics are substantially weaker than their classical counterparts. In this paper we consider the addition of a suitable conditional to First-Degree Entailment—a logic recently studied by Hannes Leitgeb under the label HYPE. We show in particular that, by formulating the theory (...) PKF over HYPE, one obtains a theory that is sound with respect to fixed-point models, while being proof-theoretically on a par with its classical counterpart KF. Moreover, we establish that also its schematic extension—in the sense of Feferman—is as strong as the schematic extension of KF, thus matching the strength of predicative analysis. (shrink)

Tourraix is an optimistic reactionary. He sets out his aim with refreshing clarity. He seeks to challenge "l'orthodoxie provisoirement établie," which denies that the Greeks were "tributaires de la représentation du monde véhiculée par leur langue... indo-européenne." Tourraix accuses the "adepts" of this "orthodoxy" of citing Dumézil when he excluded Greece from the regularity of Indo-European patterns of thought, while they reject his basic trifunctional theory. This, Tourraix insists, is not a "doctrine" or an "ideological credo," but the result of a "rational elaboration" (15-16).Tourraix is not concerned with radical outsiders. He dismisses the whole of Said's Orientalism because of the latter's blunder in referring to the chorus of the Persae as women. He warns that Bernal should not be taken seriously because his works are not founded on a "scientific hypothesis but on ideological presuppositions" (75). Tourraix's opponents are the professional classicists, notably Martin West, Walter Burkert, and Ruth Edwards. These promote the idea of a substantial Southwest Asian influence on Greek civilization but are unconcerned with Egypt. In the terminology of this reviewer, Tourraix's polemic is not against the "Revised Ancient Model" but as a supporter of the "Extreme" version, he opposes the "Broad Aryan Model."Tourraix's two centers of concern are Troy and Thebes. Troy interests him as a marginal entity between Greek and Barbarian. He admits that pottery and Hittite texts indicate that there were Mycenaean influences in the Troad. On the other hand, he rightly points out that Homer Hellenized the Trojans more than evidence from other sources can sustain. It has also been impossible to correlate the Homeric version of the city's fall with the date and scale of the destructions of Troy VI, VIIa, and VIIb. Tourraix therefore follows the hypothesis of Paul Wathelet that the destruction described in the epics was not that of an unimportant settlement on the Dardanelles but was really that of the great Greek city of Thebes, which was undoubtedly destroyed in the thirteenth century B.C.E.This is just one example of Tourraix's general approach, which is not to accept things at face value but to probe more deeply. On the central theme of his [End Page 629] book, he agrees that many Greek myths and legends would suggest "Oriental" connections and origins and that much Greek iconography appears to be "Oriental" or Egyptian (75). But he knows that such symbols were devoid of content (23). Unfortunately for his scientific credentials, however, he frequently has to rely on the words probablement or peut-être to see Indo-European essences behind the Oriental forms (e.g., 22-23).Clearly Tourraix has always been concerned with Indo-European "cultures." He has published extensively on both Greeks and Persians and the relations between them. When looking at Greek culture, he sees three main indicators of "l'héritage indo-européen." The first is language: He takes a Whorfian view of its determining power and is unconcerned that less than 40 percent of the Greek vocabulary has known Indo-European cognates. The second indicator is trifunctionalism: Tourraix sees the Indo-European base whenever he encounters a triple. Three, however, is an attractive number to speakers of many languages. The Christian Trinity appears to have originated among Aramaic speakers, and Mesopotamian and Phoenician cities had the same tripartite division of the male inhabitants into citizen, resident alien, and slave that later occurred in the Greek poleis. Thus, besides its vagueness, trifunctionalism is not an... (shrink)

Martin Hoffmann bietet eine Grundlegung protestantischer Ethik im Schnittfeld von europäischer Ethiktradition und lateinamerikanischer Theologie. Orientiert an paulinischem Denken fragt er nach der ethischen Identität von Christen und Christinnen jenseits von Biblizismus und Relativismus. Er entwickelt den Weg zu einem adäquaten ethischen Urteil im jeweiligen Kontext und zeigt an ausgewählten Feldern materialer Ethik, wie eine ethische Hermeneutik im Horizont der globalen ethischen Herausforderungen der Gegenwart aussehen kann.

Scientific discoveries are often to some degree influenced by luck. Whether luck’s influence is at odds with common-sense intuitions about responsibility, is the central concern of the philosophical debate about moral luck. Do scientists acknowledge that luck plays a role in their work and – if so – do they consider it morally problematic? The present article discusses the results of four focus groups with scientists, who were asked about their views on luck in their fields and its moral implications. (...) The participants underscored circumstantial luck as a key dimension of luck in science. Nevertheless, most participants insisted that there are ways of executing ‘control’ in science: They believe that virtues and skills can increase one’s chances for success. The cultivation of these skills and virtues was considered a reasonable ground for pride. Prizes and rewards were rarely tied to personal desert, but instead to their societal function. (shrink)

The aim of the paper is to discuss the ersatz theory of Lewis’s impossible worlds, point out its undeniable benefits and demonstrate its costs. Firstly, I present two approaches to Lewis’s impossible worlds taken as constructions out of possibilia. Secondly, I evaluate the proposals using the Lewisian criteria of success concerning the well defined conception of analysis. Although appealing, I do not find the proposals fully persuasive. Thirdly, I discuss the objection from an ad hoc distinction between possible and impossible (...) worlds. I conclude that the objection does not present a special problem for the Lewisian theory. Finally, I motivate a theory of extended modal realism, to wit, modal realism enriched with concrete impossibilia. (shrink)

Resumen: El tema del presente artículo es la recepción y radicalización heideggeriana de la aporía del tiempo y el alma en Aristóteles en los textos del periodo conocido como la década fenomenológica. La cuestión acerca de si habría o no tiempo en caso de que no existiera el alma conduce a una difícil aporía que queda sin respuesta en el corpus aristotelicum. Heidegger piensa que el planteamiento aporético muestra que Aristóteles intuye ya que el Dasein mismo debe considerarse fundamentalmente tiempo. (...) Puesto que el tiempo es la determinación básica de la existencia humana, el Dasein sería imposible sin el tiempo. En otras palabras, no habría Dasein sin tiempo.: The subject of the present paper is Heidegger’s reception and radicalization of Aristotle’s aporia of time and soul in the texts of the period known as the phenomenological decade. The question about whether there would be time without the existence of soul leads to a difficult aporia which remains unanswered in the corpus aristotelicum. Nevertheless, Heidegger believes that this aporetical approach shows that Aristotle already sensed that Dasein itself is to be considered fundamentally as time. Since time is the basic determination of human existence, Dasein would be impossible without time. In other words, there would not be a Dasein without time. (shrink)

In these original and imaginative essays, delivered as the Tanner Lectures at the University of California, Berkeley in 2005, the philosopher Axel Honneth attempts to rescue the concept of reification by recasting it in terms of the philosophy of recognition he has been developing over the past two decades.

Philosophy underwent a corresponding theatrical shift in the modern era, most importantly through the work of Kierkegaard, Nietzsche, Sartre, and Camus.

Ethics and Organizations provides a rich and valuable overview of an increasingly important issue for management and organizations in contemporary society. Debates about equal opportunities, environmental responsibility, consumer redress, and corporate governance have given ethics a prominent place in the study of organizations in their social and natural environments. Within the organization, new management styles that seek to energize employees by manipulating their beliefs have highlighted the moral-ethical principles at issue in contemporary management. At the same time, debates around postmodernism (...) and relativism have moved ethics to a new centrality in contemporary social theory. This volume addresses the questions that these and other developments raise for the study of management and organizations, from a multidisciplinary perspective. Ethics and Organizations will be invaluable to advanced-level students and academics engaged in analyzing the moral, political, and ethical dimensions of organization theory and organizational practice.

An evolutionary theory of schizophrenia needs to address all symptoms associated with the condition. Burns' framework could be extended in a way embracing behavioural signs such as catatonia. Burns' theory is, however, not specific to schizophrenia. Since no one single symptom exists that is pathognomonic for “schizophrenia,” an evolutionary proposal of psychiatric disorders raises the question whether our anachronistic psychiatric nosology warrants revision.
