In addressing thescientific study of consciousness, Crick and Koch state, It is probable that at any moment some active neuronal processes in your head correlate with consciousness, while others do not: what is the difference between them? (1998, p. 97). Evidence from electrophysiological and brain-imaging studies of binocular rivalry supports the premise of this statement and answers to some extent, the question posed. I discuss these recent developments and outline the rationale and experimental evidence for the interhemispheric switch hypothesis (...) of perceptual rivalry. According to this model, the perceptual alternations of rivalry reflect hemispheric alternations, suggesting that visual consciousness of rivalling stimuli may be unihemispheric at any one time (Miller et al., 2000). However, in this paper, I suggest that interhemispheric switching could involve alternating unihemispheric attentional selection of neuronal processes for access to visual consciousness. On this view, visual consciousness during rivalry could be bi hemispheric because the processes constitutive of attentional selection may be distinct from those constitutive of visual consciousness. This is a special case of the important distinction between the neuronal correlates and constitution of visual consciousness. (shrink)

Cognitive functions like perception, memory, language, or consciousness are based on highly parallel and distributed information processing by the brain. One of the major unresolved questions is how information can be integrated and how coherent representational states can be established in the distributed neuronal systems subserving these functions. It has been suggested that this so-called ''binding problem'' may be solved in the temporal domain. The hypothesis is that synchronization of neuronal discharges can serve for the integration of distributed neurons into (...) cell assemblies and that this process may underlie the selection of perceptually and behaviorally relevant information. As we intend to show here, this temporal binding hypothesis has implications for the search of the neural correlate of consciousness. We review experimental results, mainly obtained in the visual system, which support the notion of temporal binding. In particular, we discuss recent experiments on the neural mechanisms of binocular rivalry which suggest that appropriate synchronization among cortical neurons may be one of the necessary conditions for the buildup of perceptual states and awareness of sensory stimuli.

The relationship between brain activity and conscious visual experience is central to our understanding of the neural mechanisms underlying perception. Binocular rivalry, where monocular stimuli compete for perceptual dominance, has been previously used to dissociate the constant stimulus from the varying percept. We report here fMRI results from humans experiencing binocular rivalry under a dichoptic stimulation paradigm that consisted of two drifting random dot patterns with different motion coherence. Each pattern had also a different color, which both (...) enhanced rivalry and was used for reporting which of the two patterns was visible at each time. As the perception of the subjects alternated between coherent motion and motion noise, we examined the effect that these alternations had on the strength of the MR signal throughout the brain. Our results demonstrate that motion perception is able to modulate the activity of several of the visual areas which are known to be involved in motion processing. More specifically, in addition to area V5 which showed the strongest modulation, a higher activity during the perception of motion than during the perception of noise was also clearly observed in areas V3A and LOC, and less so in area V3. In previous studies, these areas had been selectively activated by motion stimuli but whether their activity reflects motion perception or not remained unclear; here we show that they are involved in motion perception as well. The present findings therefore suggest a lack of a clear distinction between ?processing? versus ?perceptual? areas in the brain, but rather that the areas involved in the processing of a specific visual attribute are also part of the neuronal network that is collectively responsible for its perceptual representation.

This book focuses on Albert Einstein and his interactions with, and responses to, various scientists, both famous and lesser-known. It takes as its starting point that the discussions between Einstein and other scientists all represented a contribution to the edifice of general relativity and relativistic cosmology. These scientists with whom Einstein implicitly or explicitly interacted form a complicated web of collaboration, which this study explores, focusing on their implicit and explicit responses to Einstein s work. This analysis uncovers latent undercurrents, (...) indiscernible to other approaches to tracking the intellectual pathway of Einstein to his general theory of relativity. The interconnections and interactions presented here reveal the central figures who influenced Einstein during this intellectual period. Despite current approaches to history presupposing that the efforts of scientists such as Max Abraham and Gunnar Nordström, which differed from Einstein s own views, be relegated to the background, this book shows that they all had an impact on the development of Einstein s theories, stressing the limits of approaches focusing solely on Einstein. As such, General Relativity Conflict and Rivalries proves that the general theory of relativity was not developed as a single, coherent construction by an isolated, brooding individual, but, rather, that it came to fruition through Einstein's conflicts and interactions with other scientists, and was consolidated by his creative processes during these exchanges.

The author considers how constructivism, presently known to us essentially as a theory for generating rules of social cooperation, embodies a certain conception of justification that in turn may be thought of as a general theory. It is argued that moral realism and projectivism are by turns platitudinous and unsatisfactory as conceptions of justification; by contrast the general conception of justification in constructivism makes sense of reason giving and coherent rivalry. The author argues that once the right picture of (...) justification is in place, the picture constructivism illustrates or embodies, the problem of moral ontology disappears. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Imitation, Mirror Neurons, and Mimetic Desire:Convergence Between the Mimetic Theory of René Girard and Empirical Research on ImitationScott R. GarrelsIntroductionUntil recently, the pervasive and primordial role of imitation in human life was either largely ignored or misunderstood by empirical researchers. This is no longer the case. It is now clear that investigations on human imitation are among the most profound and revolutionary areas of research contributing to the future (...) of a more unified and coherent understanding of the cognitive and social sciences. This ever-growing body of research has profound implications for a better understanding of the development and structure of human psychosocial functioning as well as cultural evolution, yet current applications lack insight into two essential aspects of human imitation: (1) its elemental role in generating uniquely human forms of relational competition, rivalry, and violence; and (2) the historical and anthropological role of religious /cultural beliefs and practices in transforming the effects of human imitation into viable and sustainable communities. Rene Girard's Mimetic Theory offers empirical researchers an already elaborated explanatory model that illuminates the way in which imitation is foundational to these universal human phenomena. Yet astonishingly, there have been no substantial studies concerning the critical question of human imitation that have applied and synthesized recent empirical research with the mimetic theory of human motivation and religious and cultural evolution.The initiation of such a detailed and comparative analysis is essential to understanding not only the historical relationship between culture and religion (and ultimately the evolution of the human species) but perhaps more importantly the pressing and complex relationship between violence, religion, and contemporary society. The mimetic theory of religion helps bring to light the mechanisms of social mimesis that produce the self-other distortions characteristic of behaviors ranging from primitive sacrificial rituals to the abhorred [End Page 47] atrocities of recent history; yet it also fundamentally elucidates the creative and historical role of the religious and cultural insights and practices based on human mimetic dynamics that continue to be indispensable in fostering alternative, nonviolent forms of progress and social cooperation in our contemporary world.The purpose of this article, then, is to advance the interdisciplinary dialogue first embarked on by Jean-Michel Oughourlian (1982), and continued in more detail by Eugene Webb (1993), concerning the convergence between empirical research on imitation and René Girard's theory of psychological mimesis. Psychological mimesis1 is the tendency of human beings to imitate the gestures, behaviors, intentions, and desires of other persons; it is the very cornerstone upon which the entire work of Girard is constructed. From this foundation, Girard has made a number of bold claims about human nature and the resulting origin and structure of human culture and religion. Girard's work is immense in scope and has far reaching implications across such diverse disciplines as anthropology, primitive religion, psychology, literary analysis, theology, and philosophy. Any theory attempting to cover this much ground will undoubtedly draw an enormous amount of criticism, and Girard's work has been no exception. Regardless of this, "Girard's hypotheses about the pragmatics of imitative interaction, and more specifically, about the influence of imitation on motivation, represent a unique and significant contribution that merits a careful examination" (Livingston 1992, xvi).The ability of mimetic theory to effectively address the various disciplines it claims to interpret will depend significantly upon its capacity to clarify and validate the primordial role of mimesis in psychosocial development and functioning. Webb (1993) has emphasized that while Girard's work has many broader anthropological and historical implications, the most essential aspect of his theory is that of psychological mimesis. On this point Webb concluded:Thus there is good reason to think not only that [psychological mimesis] deserves a careful hearing but also that it should prove widely useful for psychologists in providing an explanatory framework for the sorts of systematic relationship that many are currently investigating.(213)While Paisley Livingston (1992) has attempted a systematic presentation of Girard's ideas on mimesis, to my knowledge the "careful hearing" that Webb called for has not taken place through an engagement with the empirical sciences. This is remarkable when one considers the enormous output of imitation research... (shrink)

Imre Lakatos' "methodology of scientific research programs" and Alasdair MacIntyre's "tradition-constituted enquiry" are two sustained attempts to overcome the assumptions of logical empiricism, while saving the appearance that theory-change is rational. The key difference between them is their antithetical stand on the issue of incommensurability between large-scale theories. This divergence generates other areas of disagreement; the most important are the relevance of the historical record and the presence of decision criteria that are common to rival programs. I show that Lakatos' (...) rejection of the incommensurability thesis and dismissal of actual history are motivated by the belief that neither are compatible with the rationality of theory-change. If MacIntyre can deny the necessity of dispensing with the historical record, and show that incommensurability and the consequent absence of shared decision criteria are compatible with rationality in theory-change, then Lakatos' argument will lose its force, and MacIntyre will better honor the intention to take seriously the historicality of science. I argue that MacIntyre can dissolve tensions between incommensurability and rationality in theory-change if he is able, first, to distinguish a sense of the incommensurability thesis that preserves genuine rivalry between theories, and second, to show that the possibility of rationality in theory-change depends not on the presence of common decision criteria, but on the fact that traditions can fail by their own standards. After reconstructing and examining the argument, I conclude that the notion of a tradition's "internal failure" is coherent, but that it leaves crucial questions about the epistemology and ontology of traditions that must be answered if MacIntyre's proposal is to constitute a genuine improvement on Lakatos.

In lieu of an abstract, here is a brief excerpt of the content:The New Liberalism of L. T. Hobhouse and the Reenvisioning of Nineteenth-Century UtilitarianismDavid WeinsteinIn the eyes of some, modern liberal theorizing has fallen victim to tyrannizing conceptual dualisms that have rendered it a tedious dialogue of predictable positioning and strident partisanship. On the one hand those who dream the dream of unencumbered selfhood are said to be locked in a bitter struggle with those who long for the rebirth (...) of encumbering community. On the other hand and in a not wholly unrelated way, Kantians are supposedly and forever beating back the phoenix of consequentialism. In short, the tyrannizing dualisms of individualism vs. communitarianism and Kantianism vs. consequentialism allegedly and detrimentally channel much modern liberal theorizing.But such rivalries, however real or fanciful, need not be philosophical liberalism’s singular fate. Nor do these rivalries exclusively characterize its variegated past. My aim is to challenge the cogency and expose the historical limitations of one of these tyrannizing dualisms, namely that between Kantianism and consequentialism, by way of examining L. T. Hobhouses’s new liberalism. In my view this seeming rivalry within liberalism is a convenient straw man readily weakened by more scrupulous attention to liberalism’s new liberal past. 1 [End Page 487]Principally, I hope to show that Hobhouse’s rendering of liberalism privileged good but not at the price of stultifying welfare pooling, individuality but not at the cost of pitiless individualism. Hobhouse’s version of new liberalism may not have been quite utilitarian, but it nevertheless took maximizing good seriously while retaining a firm commitment to strong moral rights and the flourishing of individuals as ends. Hobhouse’s new liberalism, then, was as robustly juridical and as authentically liberal as it was fundamentally consequentialist.The Rational Good and Moral PersonalitySelf-realization was the normative hinge of Hobhouse’s new liberalism. Self-realization, in turn, can not be understood without examining Hobhouse’s notion of the rational good. Hence, The Rational Good, published later in his life in 1921, occupies a vital position in his thought though recent scholarship has all but ignored this work. 2In this work Hobhouse begins by asking “whether there is a Rational, and therefore demonstrable, standard of values to which the actions of man and the institutions of society may be referred for judgment.” 3 For Hobhouse, such a standard exits and the remainder of the book endeavors to persuade us accordingly.In a chapter entitled “The Good,” Hobhouse claims that the proposition that something is good expresses a “disposition” and asserts a “fact.” The disposition consists of a favorable “practical attitude” towards pleasurable feelings, which certain (self-realizing) experiences invariably entail. In Hobhouse’s words “the judgment ‘This is good’ is not only the expression of an attitude but also the assertion of a fact, and the fact which it asserts is a harmony between an experience and a feeling.” 4 Hence, we deem good only those self-realizing experiences that are harmonious in the sense that they generate feelings of pleasure. A pleasure-producing experience is a harmonious experience and, assuming that it is also self-realizing, we are disposed to pronounce it “good.”Now separate harmonious experiences, unless rationally coordinated, will likely clash, thereby generating overall disharmony or pain. Experiences which we separately judge as good may turn out to be bad on the whole. A good life, therefore, is a satisfying coherent life. Only a rationally coherent life is fully self-realizing and constitutes the rational good. In short “that what we reasonably call good or what is really good must be a harmony of the [End Page 488] totality of feeling with the totality of experience so far as it affects feeling. Thus, Practical Reason is the effort of the mind towards harmony within itself, and with nature.” 5But if, for Hobhouse, practical reason is an ongoing “effort” in coordination, then the fully rational good is a formal ideal which actual lives succeed more or less skillfully in realizing. Hence, Hobhouse also introduces the “realized good” as the practically possible good, and the distance one goes in realizing his or her own good is, as Hobhouse says, “what we call character.” 6 To...

The social organization of the Chinese diaspora in Malaysia has emerged as a very diversified phenomenon so that it is hard to speak of a coherent social and cultural community. Starting from the case of George Town (Penang), a port city once part of the British Empire and subsequently incorporated in present-day Malaysia, the article will illustrate the various forms of social organization developed by the Chinese in the longue durée. The analysis of the Chinese diaspora in George Town (Penang) (...) based on long-term fieldwork helps to draw attention especially to its internal tensions, rivalries and even open and at times enduring conflicts. Through the notions of network and corporate group, distinctive of the Manchester school, by means of a dynamic analysis, thus mindful of specific historical processes, this article will examine the underlying modalities of organizational changes that occurred in this diasporic society within the colonial and national societies. Thus, the article avoids an essentialist vision based on a uniformity and cultural unity of these immigrant communities. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Seventeenth-Century Catholic Polemic and the Rise of Cultural Rationalism: An Example from the EmpireSusan RosaIn Galileo’s Dialogue Concerning the Two Chief World Systems Sagre-do, an intelligent, cultivated, and well-traveled young man who is persuaded of the truth of arguments in favor of the Copernican opinion presented by the philosopher Salviati, dismisses the counter-arguments of the Aristotelian Simplicio with sympathetic condescension: “I pity him,” he proclaims,no less than I should (...) some fine gentleman who, having built a magnificent palace at great trouble and expense, employing hundreds and hundreds of artisans, and then beholding it threatened with ruin because of poor foundations, should attempt, in order to avoid the grief of seeing the walls destroyed, adorned as they are with so many lovely murals; or the columns fall, which sustain the superb galleries, or the gilded beams, or the doors spoiled, or the pediments and the marble cornices, brought in at so much cost—should attempt, I say, to prevent the collapse with chains, props, iron buttresses, and shores. 1 [End Page 87]This elegant simile, which suggests that the fine gentleman can only preserve his palace by destroying its beauty, is meant to evoke the dilemma of the scholastic philosopher who is confronted by the evident disintegration of his intellectual home. Like the desperate owner who seeks to shore up his real palace, he must rebuild a philosophical edifice whose apparent beauty and coherence have been achieved at the expense of substance and can only be preserved by recourse to means so ugly and inadequate that they destroy even the illusion of credibility.Such a dilemma, I would argue, was the legacy bequeathed to many defenders of traditional religion in the seventeenth century by more than one hundred years of confessional rivalry. To simplify a complex process, this lengthy period of controversy and apologetic, to say nothing of warfare and mutual persecution, had generated a discourse which objectified and prob-lematized religion, making it something to think about rather than to think with. 2 In other words, the formal statements of conviction issued in the wake of the Reformation by competing denominations within Christendom, like the Catechism of the Council of Trent, the Augsburg Confession, the Genevan Confession, or the Thirty-Nine Articles of the Church of England had encouraged the development of the notion of religion as adherence to a set of propositions. As Peter Harrison has explained, this creation of a propositional religion in turnenabled discussion of the merits of other “religions” conceived to exist similarly as sets of beliefs. The truth or falsity of a religion had become a function of the truth or falsity of the propositions which constituted it. True religion... [had become]... a body of certain knowledge. 3Harrison’s remarks are significant because they suggest that the origins of rationalized discourse about religion and its consequent transformation from a way of thinking to an object of thought are to be found squarely within orthodoxy itself. 4To be specific, the competing content of official doctrinal pronouncements led not only to the comparison of the religions but implicitly to their emergence as subjects of a discourse which proposed reason as the norm, a [End Page 88] development clearly reflected in the wave of pamphlets, broadsides, printed disputations, and formal polemical treatises written in both Latin and the vernacular languages which poured from the presses of Catholic and mainstream Protestant denominations in England and on the continent throughout the seventeenth century. In this literature, Protestants accused Catholics of “superstition” and “idolatry,” while Catholics urged potential converts to compare the religions with a view to discovering their “marks of truth,” argued for the compatibility of Catholic faith and “natural light,” and identified heresy, on the contrary, with unreason, passion, lust, and self-contradiction. On both sides of the confessional fence, polemicists frequently insisted that religious discussion conform to the rules of logic, accusing one another of failing to argue from incontrovertible first principles, and of succumbing to the fatal dangers of petitio principii and circular reasoning. In other words, they claimed that in religious matters poor argumentation is a sure sign of error, and it would not be... (shrink)

As Freeman states, “when one puts together the Gospels, the letters of Paul, the Book of Revelation and the Old Testament, there is no sense (...) of a coherent ‘axiomatic’ base on which to build theological truths”.

There are at least two different aspects of our rational evaluation of agents’ doxastic attitudes. First, we evaluate these attitudes according to whether they are supported by one’s evidence (substantive rationality). Second, we evaluate these attitudes according to how well they cohere with one another (structural rationality). In previous work, I’ve argued that substantive and structural rationality really are distinct, sui generis, kinds of rationality – call this view ‘dualism’, as opposed to ‘monism’, about rationality – by arguing that the (...) requirements of substantive and structural rationality can come into conflict. In this paper, I push the dialectic on this issue forward in two main ways. First, I argue that the most promising ways of resisting the diagnosis of my cases as conflicts still end up undermining monism in different ways. Second, supposing for the sake of argument that we should understand the cases as conflicts, I address the question of what we should do when such conflicts arise. I argue that, at least in a prominent kind of conflict case, the coherence requirements take precedence over the evidential requirements. (shrink)

Logical pluralism is the view that there is more than one correct logic. This very general characterization gives rise to a whole family of positions. I argue that not all of them are stable. The main argument in the paper is inspired by considerations known as the “collapse problem”, and it aims at the most popular form of logical pluralism advocated by JC Beall and Greg Restall. I argue that there is a more general argument available that challenges all variants (...) of logical pluralism that meet the following three conditions: that there are at least two correct logical systems characterized in terms of different consequence relations, that there is some sort of rivalry among the correct logics, and that logical consequence is normative. The hypothesis I argue for amounts to conditional claim: If a position satisfies all these conditions, then that position is unstable in the sense that it collapses into competing positions.

Some combinations of attitudes--of beliefs, credences, intentions, preferences, hopes, fears, and so on--do not fit together right: they are incoherent. A natural idea is that there are requirements of "structural rationality" that forbid us from being in these incoherent states. Yet a number of surprisingly difficult challenges arise for this idea. These challenges have recently led many philosophers to attempt to minimize or eliminate structural rationality, arguing that it is just a "shadow" of "substantive rationality"--that is, correctly responding to one's (...) reasons. -/- In *Fitting Things Together*, Alex Worsnip pushes back against this trend--defending the view that structural rationality is a genuine kind of rationality, distinct from and irreducible to substantive rationality, and tackling the most important challenges for this view. In so doing, he gives an original positive theory of the nature of coherence and structural rationality that explains how the diverse range of instances of incoherence can be unified under a general account, and how facts about coherence are normatively significant. He also shows how a failure to focus on coherence requirements as a distinctive phenomenon and distinguish them adequately from requirements of substantive rationality has led to confusion and mistakes in several substantive debates in epistemology and ethics. -/- Taken as a whole, Fitting Things Together provides the first sustained defense of the view that structural rationality is a genuine, autonomous, unified, and normatively significant phenomenon.

The rivalry between religions is obvious on a number of fronts: in wars between Christians, Muslims, and Hindus; in sectarian violence between Catholics and Protestants, or between Shia and Sunni; in the persecution of doctrinal heretics; in the splintering of new sects along doctrinal lines; in efforts to proselytize; and so on.

Rivalry is an attempt to understand facets of entrepreneurial societies by integrating the economic analysis with historical, political and psychological considerations, customarily shunned by economists. The author argues that decisions to make new business ventures, and readiness to take risks are both related to concepts of ranking hierarchies on local, national or international levels. He then constructs a theory of business enterprise and of rivalry supported by evidence on entrepreneurship, innovation, advertising, all examined with their historical, political or (...) organisational concerns. This notion of rivalry among businessmen is used to derive guidelines for anti-trust legislation. Instead of pricing, profitability, concentration ratios and other criteria used today to infer non-competitive behaviour, he suggests using a measure of a firm's relative rate of innovation to infer it. By extending the notion of rivalry to the political sphere, national and international, guidelines are derived to evaluate the performance of state-owned enterprises and to examine policies related to free trade.

RIVALRY AND CENTRAL PLANNING: THE SOCIALIST CALCULATION DEBATE RECONSIDERED by Don Lavoie. New York: Cambridge University Press, 1985. 208 pp., $34.95.

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)

A central issue in epistemology concerns the connection between truth and justification. The burden of our paper is to explain this connection. Reliabilism, defended by Goldman, assumes that the connection is one of reliability. We argue that this assumption is too strong. We argue that foundational theories, such as those articulated by Pollock and Chisholm fail to elucidate the connection. We consider the potentiality of coherence theories to explain the truth connection by means of higher level convictions about probabilities, (...) which we call doxastic ascent, and defend such a theory. Our defense appeals to the work of Reid and contemporary cognitive psychology in order to account for the psychological reality of higher level evaluations. (shrink)

This paper aims to contribute to our understanding of the notion of coherence by explicating in probabilistic terms, step by step, what seem to be our most basic intuitions about that notion, to wit, that coherence is a matter of hanging or fitting together, and that coherence is a matter of degree. A qualitative theory of coherence will serve as a stepping stone to formulate a set of quantitative measures of coherence, each of which seems (...) to capture well the aforementioned intuitions. Subsequently it will be argued that one of those measures does better than the others in light of some more specific intuitions about coherence. This measure will be defended against two seemingly obvious objections. (shrink)

Natural languages are riddled with context-sensitivity. One and the same string of words can express many different meanings on occasion of use, and yet we understand one another effortlessly, on the fly. How do we do so? What fixes the meaning of context-sensitive expressions, and how are we able to recover the meaning so effortlessly? -/- This book offers a novel response: we can do so because we draw on a broad array of subtle linguistic conventions that determine the interpretation (...) of context-sensitive items. Contrary to the dominant tradition, which maintains that the meaning of context-sensitive language is underspecified by grammar and that interpretation relies on non-linguistic cues and speakers' intentions, this book argues that meaning is determined entirely by discourse conventions, rules of language that have largely been missed and the effects of which have been mistaken for extra-linguistic effects of an utterance situation on meaning. The linguistic account of context developed here sheds new light on the nature of linguistic content and the interaction between content and context. At the same time, it provides a novel model of context that should constrain and help evaluate debates across many subfields of philosophy where appeal to context has been common, often leading to surprising conclusions such as epistemology, ethics, value theory, metaphysics, metaethics, and logic.

In lieu of an abstract, here is a brief excerpt of the content:Beyond Rivalry?Rethinking Community in View of Apocalyptical ViolenceAndreas Oberprantacher (bio)But the republic of crime must also be the republic of the suicide of criminals, and down to the last among them—the sacrifice of the sacrificers unleashed in passion.—Jean-Luc Nancy, The Inoperative CommunityThe Crisis and Apocalyptic Intensification of RivalryAt first it seemed as if the "rivalry between two rates of speed"1 set at the center of Derrida's essay (...) "No Apocalypse, Not Now," published more than twenty years ago in Diacritics, had finally come to an end, at least in the form of a general and unmistakable division of the world into two competing geopolitical units. Following the breakdown of the USSR, the former super-enemy of the industrialized Northwest, that part of the world that claimed and still claims to be the sole referent of the adjective free, the dynamics of ideological rivalry had, at first, lost considerable momentum. After half a century of mostly symmetrical even if undeclared wars, the period from 1989 to 1991 was truly significant, [End Page 175] for it marked a moment of epistemological crisis, a moment when political fractions that derived their identity from a binary tension were all of a sudden stunned: no visible enemy anymore to deter, no willing scapegoat to blame, just eschatological abandonment.The aftershocks of this historical event can be traced in today's commentaries on and analyses of the political situation: It is certainly no coincidence that two of the most influential US-American political analysts, Samuel Huntington and Bruce Hoffman, both at the same time direct their attention toward questions about the conditions of social identity and cohesion, though from inverted perspectives. In his recent book, Who Are We? The Challenges to America's National Identity (2004), Huntington bemoans the "deconstruction of the American identity,"2 as it challenges—along with certain political developments—"the substance, and the desirability of this concept of America."3 Huntington's fervent interest in US-American identity and his call for its renewal become readily comprehensible when read against the background of his concern that an existential threat might again be imminent, possibly in the form of jihadist terrorism. In Huntington's argument, however, the United States's potential confrontation with militant Islamist movements—the explicit subtext of his book—is not assessed only in terms of political risks and military expenditures; for Huntington, this confrontation also holds out a unique chance of rediscovering one's own (lost, forgotten) identity. Revealing himself as an attentive reader of Carl Schmitt's The Concept of the Political, Huntington argues that "the absence of an ideological threat produced an absence of purpose.... The ideal enemy for America would be ideologically hostile, racially and culturally different, and militarily strong enough to pose a credible threat to American security."4While Huntington is concerned with reaffirming and securing a phantasmagoric vision of the United States's past glory, Hoffman, on the other hand, may be mentioned as a political analyst deeply worried about the inverse aspect of the epistemological crisis, i.e., worried by the fact that "the United States has utterly failed to fulfill the timeless admonition to 'know your enemy'"5 by declaring an all too abstract global war on terrorism. In his commentary, published in March 2007 under the title "Fighting Blind: We Can't Win if We Don't Know the Enemy" in the Washington Post, he argues that a long-term strategy is desperately needed to identify "our adversaries, who are much too elusive and complicated to be vanquished by mere decapitation."6Taking Huntington's and Hoffman's positions seriously as paradigmatic examples of a wider and well-established discursive strategy that calls for a renewed need for binary-opposed collective identities—us/them; the coalition [End Page 176] of the willing/the axis of evil—in order to affirm a state of potentially ubiquitous and highly moralized rivalry, one may well argue with Schmitt that "a new nomos of the earth" is immanent.7 In Schmitt's understanding, such a new paradigm of warfare will no longer be characterized by relative understandings of enmity, but by enemies declared "totally criminal...

Economic exchange constitutes the basis of many, but not all, aspects of human cooperation. The incentives overlap with, but remain distinct in important ways, from other fundamental aspects of cooperation, including the organization of collective violence for combat. The specific alignment of sometimes-conflicting goals helps inform the construction of political ideology.

According to many philosophers, rationality is, at least in part, a matter of one’s attitudes cohering with one another. Theorists who endorse this idea have devoted much attention to formulating various coherence requirements. Surprisingly, they have said very little about what it takes for a set of attitudes to be coherent in general. We articulate and defend a general account on which a set of attitudes is coherent just in case and because it is logically possible for the attitudes (...) to be jointly satisfied in the sense of jointly fitting the world. In addition, we show how the account can help adjudicate debates about how to formulate various rational requirements. (shrink)

This paper considers further evidence that five comic poets as opposed to three competed at the Lenaia and City Dionysia festivals in Athens during the Peloponnesian War. Aristophanes’ abuse of his comic rivals Phrynichos, Ameipsias and Lykis in the opening scene ofFrogs, produced at the Lenaia of 405, is interpreted as a response to his immediate competitors at the dramatic contest that year. A survey of the evidence elsewhere in comedy suggests that comic poets usually reserved such attacks on rival (...) poets for occasions when all were in direct competition at the same festival. Further analysis of Aristophanes’ competitive strategies also suggests these poets immediate participation in the festival and therefore that five poets competed at the Lenaia that year. (shrink)

This target article presents a new computational theory of explanatory coherence that applies to the acceptance and rejection of scientific hypotheses as well as to reasoning in everyday life, The theory consists of seven principles that establish relations of local coherence between a hypothesis and other propositions. A hypothesis coheres with propositions that it explains, or that explain it, or that participate with it in explaining other propositions, or that offer analogous explanations. Propositions are incoherent with each other (...) if they are contradictory, Propositions that describe the results of observation have a degree of acceptability on their own. An explanatory hypothesis is acccpted if it coheres better overall than its competitors. The power of the seven principles is shown by their implementation in a connectionist program called ECHO, which treats hypothesis evaluation as a constraint satisfaction problem. Inputs about the explanatory relations are used to create a network of units representing propositions, while coherende and incoherence relations are encoded by excitatory and inbihitory links. ECHO provides an algorithm for smoothly integrating theory evaluation based on considerations of explanatory breadth, simplicity, and analogy. It has been applied to such important scientific cases as Lovoisier's argument for oxygen against the phlogiston theory and Darwin's argument for evolution against creationism, and also to cases of legal reasoning. The theory of explanatory coherence has implications for artificial intelligence, psychology, and philosophy. (shrink)

This paper proposes a description of the moral obligations of economic agents. It will show that a threefold division should be adopted to distinguish moral obligations applying to their interactions in the market, obligations applying to their interactions inside business firms and obligations applying to their interactions with agents outside the market. Competition might be permissible in the first case since markets are special patterns of social interactions (called adversarial schemes). They produce their benefits when agents try to satisfy exclusive (...) preferences at the expense of others. However, moral obligations inside the firm and moral obligations outside the market are of a different nature. This argument will be developed in the two first parts of this paper. In the third part, it will outline the relevant strengths of that account in relation with two popular views of economic agents’ moral obligations: the shareholder primacy view and the stakeholder theory.

The issues of religious proselytization as well as the construction of house of worship are of main contentious topics inciting tensions between religious adherents, particularly between the minority Christians and the majority Muslims in contemporary Indonesia. This article discusses these two inter-religious problems and poses a question to extent that the competition between Muslim and Christians, both in their missionary activities and the building of new house of worship, inflicting inter-religious relation in contemporary Indonesia. Taken some cases as points of (...) discussion, this article further offers that inclusive dialogue and social justice are solutions to minimize—even to prevent—the worsening tension between Muslim and Christians.
