There is currently much interest in bringing together the tradition of categorial grammar, and especially the Lambek calculus, with the recent paradigm of linear logic to which it has strong ties. One active research area is designing non-commutative versions of linear logic (Abrusci, 1995; Retoré, 1993) which can be sensitive to word order while retaining the hypothetical reasoning capabilities of standard (commutative) linear logic (Dalrymple et al., 1995). Some connections between the Lambek calculus and computations in groups have long been (...) known (van Benthem, 1986) but no serious attempt has been made to base a theory of linguistic processing solely on group structure. This paper presents such a model, and demonstrates the connection between linguistic processing and the classical algebraic notions of non-commutative free group, conjugacy, and group presentations. A grammar in this model, or G-grammar is a collection of lexical expressions which are products of logical forms, phonological forms, and inverses of those. Phrasal descriptions are obtained by forming products of lexical expressions and by cancelling contiguous elements which are inverses of each other. A G-grammar provides a symmetrical specification of the relation between a logical form and a phonological string that is neutral between parsing and generation modes. We show how the G-grammar can be oriented for each of the modes by reformulating the lexical expressions as rewriting rules adapted to parsing or generation, which then have strong decidability properties (inherent reversibility). We give examples showing the value of conjugacy for handling long-distance movement and quantifier scoping both in parsing and generation. The paper argues that by moving from the free monoid over a vocabulary V (standard in formal language theory) to the free group over V, deep affinities between linguistic phenomena and classical algebra come to the surface, and that the consequences of tapping the mathematical connections thus established can be considerable.

Not all scientific explanations work by describing causal connections between events or the world's overall causal structure. In addition, mathematicians regard some proofs as explaining why the theorems being proved do in fact hold. This book proposes new philosophical accounts of many kinds of non-causal explanations in science and mathematics.

English summary: Marc Andre Wiegand analyzes the neo-Kantian premises of Gustav Radbruch's legal philosophy.

En dehors de Pascal en France, c'est surtout en Allemagne que tragique et tristesse ont été mis en rapport avant que leur distinction soit largement développée par Walter Benjamin dans son livre sur le drame baroque. L'opposition faite par Benjamin entre le Trauerspiel et la tragédie peut être interprétée comme l'aboutissement et l'achèvement d'une distinction courante dans la philosophie allemande depuis Hegel entre le " tragique " (antique) et le " triste " de la modernité (romantique). Si ces deux termes (...) ne sont pas ressentis en français comme formant un couple de concepts, il n'en va pas de même dans la philosophie et l'esthétique allemandes, où ils apparaissent régulièrement ensemble, exprimant soit une différence de degré (Hegel, Simmel), soit de nature (Nietzsche, Ziegler), soit enfin un rapport de polarité (Benjamin) et où se jouent des rapports différents avec le mythe et l'histoire. C'est un des grands mérites de Benjamin que d'avoir saisi cette polarité entre le tragique et le triste, qui n'avait jamais été formulée explicitement avant lui, et de l'avoir élevée au rang de théorie dans son opposition entre Trauerspiel et tragédie. Pour comprendre en profondeur les implications du concept de Trauerspiel introduit par Benjamin, et du concept de tristesse qui lui est lié, il est nécessaire de se replonger dans la tradition allemande, de connaître le milieu philosophique dans lequel Benjamin a fait ses études, en particulier les discussions autour de la philosophie de l'histoire et de la structure du temps au début du XXe siècle. Toute la pensée de Benjamin s'éclaire alors sous un jour nouveau qui permet de mieux saisir le lien entre ses écrits de jeunesse et sa pensée ultérieure. (shrink)

Despite the fact that there is considerable evidence against the causal efficacy of proximal (short-term) conscious intentions, many studies confirm our commonsensical belief in the efficacy of more distal (longer-term) conscious intentions. In this paper, I address two questions: (i) What, if any, is the difference between the role of consciousness in effective and in non-effective conscious intentions? (ii) How do effective conscious distal intentions interact with unconscious processes in producing actions, and how do non-effective proximal intentions fit into this (...) process? I argue that answers to these questions point to a picture of distal conscious intending as a form of self-programming. The metaphor of ?self-programming? will be elucidated by using a distinction between ?structuring? and ?triggering? causes. Though the self-programming metaphor does not amount to a full theory of conscious intending, I argue that it may be a useful heuristic in developing such a theory. I also argue that the metaphor is phenomenologically plausible. (shrink)

Conflicts of interest are rampant in the American medical community. Today it is not uncommon for doctors to refer patients to clinics or labs in which they have a financial interest (40% of physicians in Florida invest in medical centers); for hospitals to offer incentives to physicians who refer patients (a practice that can lead to unnecessary hospitalization); or for drug companies to provide lucrative give-aways to entice doctors to use their "brand name" drugs (which are much more expensive than (...) generic drugs). In Medicine, Money and Morals, Marc A. Rodwin draws on his own experience as a health lawyer--and his research in health ethics, law, and policy--to reveal how financial conflicts of interest can and do negatively affect the quality of patient care. He shows that the problem has become worse over the last century and provides many actual examples of how doctors' decisions are influenced by financial considerations. We learn how two California physicians, for example, resumed referrals to Pasadena General Hospital only after the hospital started paying $70 per patient (their referrals grew from 14 in one month to 82 in the next). As Rodwin writes, incentives such as this can inhibit a doctor from taking action when a hospital fails to provide proper service, and may also lead to the unnecessary hospitalization of patients. We also learn of a Wyeth-Ayerst Labs promotion in which physicians who started patients on INDERAL (a drug for high blood pressure, angina, and migraines) received 1000 mileage points on American Airlines for each patient (studies show that promotions such as this have a direct effect on a doctor's choice of drug). Rodwin reveals why the medical community has failed to regulate conflicts of interest: peer review has little authority, state licensing boards are usually ignorant of abuses, and the AMA code of ethics has historically been recommended rather than required. He examines what can be learned from the way society has coped with the conflicts of interest of other professionals --lawyers, government officials, and businessmen--all of which are held to higher standards of accountability than doctors. And he recommends that efforts be made to prohibit and regulate certain kinds of activity (such as kickbacks and self-referrals), to monitor and regulate conduct, and to provide penalties for improper conduct. Our failure to face physicians' conflicts of interest has distorted the way medicine is practiced, compromised the loyalty of doctors to patients, and harmed society, the integrity of the medical profession, and patients. For those concerned with the quality of health care or medical ethics, Medicine, Money and Morals is a provocative look into the current health care crisis and a powerful prescription for change.

Several philosophers have argued that ‘constraints’ constrain (and thereby explain) by virtue of being modally stronger than ordinary laws of nature. In this way, a constraint applies to all possible systems, for a variety of possibility that is broader (that is, more inclusive) than the variety we employ when we say that the ordinary laws of nature apply to all physically possible systems. Explanations by constraint are thus more broadly unifying than ordinary causal explanations. Philosophical examples of good candidates for (...) constraints have heretofore been drawn almost exclusively from fundamental physics. This paper argues for the existence of such constraints (even multiple levels of them) in at least one human science (linguistics), not just in physics. (shrink)

Genocide is a matter of law. It is also a matter of history. Engaging some of the most disturbing responses to the Armenian genocide, Marc Nichanian strikingly reveals the complex role played by law and history in making this and other genocides endure as contentious events. Nichanian's book argues that both law and history fail to contend with the very nature of events for which there is no archive (no documents, no witnesses). Both history and law fail to address (...) the modern reality that events can be—and are now being—perpetrated that _depend_ upon the destruction of the archive, turning monstrous deeds into nonevents. Genocide, this book makes us see, is in one sense the _destruction_ of the archive. It relies on the historiographic perversion. (shrink)

Both individually and as a collection, these essays will promote understanding and provoke further debate amongst students and established scholars alike.

Alexander Pho and Benjamin A. White respond to Nicolas Dixon’s critique of mixed martial arts (MMA) through a ‘companions in innocence’ argument. Taking up a counterexample that Dixon is quick to dismiss, the authors argue that MMA techniques are on a par with the ‘pain-leveraging’ tactics used by cyclists and that pressing for a moral distinction between cycling and MMA leads to absurd conclusions about other practices. So, because cycling is morally permissible, MMA is morally permissible. This companions in innocence (...) argument fails. But cycling can be used to develop a better, though only partial, defense of MMA. (shrink)

Standardly, epistemic peers regarding a given matter are said to be people of equal competence who share all relevant evidence. Alternatively, one can define epistemic peers regarding a given matter as people who are equally likely to be right about that matter. I argue that a definition in terms of likelihood captures the essence of epistemic peerhood better than the standard definition or any variant of it. What is more, a likelihood definition implies the truth of the central thesis in (...) the debate on peer disagreement, the so-called Equal Weight View, according to which we should give the opinions of our peers the same weight we give our own. Adopting a likelihood definition, however, does not end the debate on peer disagreement, because the alleged theoretical alternatives to the Equal Weight View, reinterpreted in the light of a likelihood definition, can in fact be shown to be compatible with this view—though the reinterpreted versions may appear less plausible than the original ones.

This article is an examination of killing in war in its moral and normative dimension – with attention given to how killing affects the acting agent. The author argues against the commonplace belief – often tacitly held if not consciously asserted – among academics, the general public, and even – if surprisingly – military professionals, that killing, including in a justified war, is always morally wrong – even when legally sanctioned and necessary to avert a greater moral wrong. This critique (...) of the “killing is wrong but in war it is necessary” trope is motivated in part by the large numbers of psychiatric battle casualties (specifically moral injury) suffered during operations in Iraq and Afghanistan, and which have attended military activity throughout history. The article approaches the issue through the field of Christian ethical reflection on just war. In building a moral framework for killing in combat, the article explores a typology of homicide, intention, double effect, love, and whether the attitudinal expectations of just warriors in the Christian tradition is realistic in combat. With this moral framework for killing in hand, this article concludes by drawing a critical distinction between moral injury and moral bruising. (shrink)

The evidence that we get from peer disagreement is especially problematic from a Bayesian point of view since the belief revision caused by a piece of such evidence cannot be modelled along the lines of Bayesian conditionalisation. This paper explains how exactly this problem arises, what features of peer disagreements are responsible for it, and what lessons should be drawn for both the analysis of peer disagreements and Bayesian conditionalisation as a model of evidence acquisition. In particular, it is pointed (...) out that the same characteristic of evidence from disagreement that explains the problems with Bayesian conditionalisation also suggests an interpretation of suspension of belief in terms of imprecise probabilities.

Crise de l'art ou consensus culturel? Aujourd'hui, l'important n'est plus, semble-t-il, que la critique esthetique ait encore a dire sur Josef Beuys mais que le Centre Pompidou puisse faire croire qu'il dit tout de lui. Le culturel, dans son mecanisme institutionnel et mediatique bien huile, apparait comme l'ultime parade que l'ordre social ait su trouver pour conjurer sa peur - ou sa haine - de l'art. Cependant la critique n'a pas a se laisser abuser ni intimider par l'artifice du consensus (...) culturel qui regne actuellement. Il lui revient de continuer a evaluer les oeuvres, pour autant que le jugement sur l'art engage aussi la societe et l'epoque dans lesquelles cet art se deploie. La reflexion esthetique ne se reduit pas au jugement de gout, elle commence avec lui et se poursuit apres lui. (shrink)

A commonly neglected feature of the so-called Equal Weight View, according to which we should give our peers’ opinions the same weight we give our own, is its prima facie incompatibility with the common picture of philosophy as an armchair activity: an intellectual effort to seek a priori knowledge. This view seems to imply that our beliefs are more likely to be true if we leave our armchair in order to find out whether there actually are peers who, by disagreeing (...) with us, force us to revise our beliefs. This article argues that the Equal Weight View should be spelled out in such a way that not only actual peer disagreement requires us to revise our beliefs, but also merely possible peer disagreement. This result is not a reductio ad absurdum of the view. Quite the opposite: it shows that the view is, contrary to appearance, compatible with our common way of doing philosophy. (shrink)

Marc Hauser puts forth the theory that humans have evolved a universal moral instinct, unconsciously propelling us to deliver judgments of right and wrong independent of gender, education, and religion. Combining his cutting-edge research with the latest findings in cognitive psychology, linguistics, neuroscience, evolutionary biology, economics, and anthropology, Hauser explores the startling implications of his provocative theory vis-à-vis contemporary bioethics, religion, the law, and our everyday lives.

Unknown peers create a problem for those epistemologists who argue that we should be conciliatory in cases of peer disagreement. The standard interpretation of ‘being conciliatory’ has it that we should revise our opinions concerning a specific subject matter whenever we encounter someone who is as competent and well informed as we are concerning this subject matter (and thus is our peer) and holds a different opinion. As a consequence, peers whom we have never encountered and who are hence unknown (...) to us are not taken into account. This, however, appears odd; not only because it is an accidental matter which peers we happen to encounter and which not, but also because it would allow people to deliberately isolate themselves from any kind of intellectual exchange on the topic under consideration. The paper argues that we should take the problem of unknown peers seriously, and that disregarding the problem is an instance of the more general mistake of assuming that evidential quality and justified believability can be dealt with separately. Moreover, a solution to the problem of unknown peers is suggested. (shrink)

Our ability to acknowledge and recognise our own identity - our 'self' - is a characteristic doubtless unique to humans. Where does this feeling come from? How does the combination of neurophysiological processes coupled with our interaction with the outside world construct this coherent identity? We know that our social interactions contribute via the eyes, ears etc. However, our self is not only influenced by our senses. It is also influenced by the actions we perform and those we see others (...) perform. Our brain anticipates the effects of our own actions and simulates the actions of others. In this way, we become able to understand ourselves and to understand the actions and emotions of others. -/- This book is the first to describe the new field of 'Motor Cognition' - one to which the author's contribution has been seminal. Though motor actions have long been studied by neuroscientists and physiologists, it is only recently that scientists have considered the role of actions in building the self. How consciousness of action is part of self-consciousness, how one's own actions determine the sense of being an agent, how actions performed by others impact on ourselves for understanding others, differentiating ourselves from them and learning from them: these questions are raised and discussed throughout the book, drawing on experimental, clinical, and theoretical bases. -/- The advent of new neuroscience techniques, like neuroimaging and direct electrical brain stimulation, together with a renewal of behavioral methods in cognitive psychology, provide new insights into this area. Mental imagery of action, self-recognition, consciousness of actions, imitation can be objectively studied using these new tools. The results of these investigations shed light on clinical disorders in neurology, psychiatry and in neuro-development. -/- This is a major new work that will lay down the foundations for the field of motor cognition.

De essays die hier zijn verzameld, gaan alle op hun manier op zoek naar wat het betekent dat wij, modernen, 'subject' zijn geworden. Voor de moderniteit, in de christelijke middeleeuwen, was God het 'subjectum', dit wil zeggen de 'drager' waarin de mens zichzelf en zijn wereld gegrondvest wist. Met de moderniteit heeft de mens die rol van 'drager' en 'subject' overgenomen: de plaats waarin hij zichzelf en zijn wereld gegrond kon weten, was voortaan enkel en alleen nog zijn eigen eindige (...) 'zelf'. De essays die Marc De Kesel hier bijeenbrengt, stellen op diverse manieren de vraag naar wat het wil zeggen dat de plaats waar wij, modernen, onszelf treffen, niet langer de plaats is waar een God ons zou hebben geschapen en evenmin de plaats waar wij zonder meer bij onszelf aanwezig zouden zijn (en onze drager, ons eigen 'subjectum' zou zijn). Aan de hand van een aantal hedendaagse (Lacaniaanse, Bataillaanse en andere) denkschema's tracht hij aan te tonen hoe die plaats ons wezenlijk vreemd blijft, omdat wij drager-subject zijn geworden van iets dat ons in laatste instantie blijft ontsnappen; alleen moet dat 'transcendente' niet langer in een of andere verre God worden gezocht, maar in de banale woordenstroom waar ons dagelijks bestaan op drijft. De Kesels essays gaan vaak rechtstreeks in op concrete situaties, wat ze dwingt hun gedachtengang dicht bij de realiteit te houden. Dit kan een denken dat onze filosofische traditie niet schuwt, alleen maar ten goede komen. (shrink)

This paper concerns how motor actions are neurally represented and coded. Action planning and motor preparation can be studied using a specific type of representational activity, motor imagery. A close functional equivalence between motor imagery and motor preparation is suggested by the positive effects of imagining movements on motor learning, the similarity between the neural structures involved, and the similar physiological correlates observed in both imaging and preparing. The content of motor representations can be inferred from motor images at a (...) macroscopic level, based on global aspects of the action and the motor rules and constraints which predict the spatial path and kinematics of movements. A more microscopic neural account calls for a representation of object-oriented action. Object attributes are processed in different neural pathways depending on the kind of task the subject is performing. During object-oriented action, a pragmatic representation is activated in which object affordances are transformed into specific motor schemas. Animal as well as human clinical data implicate the posterior parietal and premotor cortical areas in schema instantiation. A mechanism is proposed that is able to encode the desired goal of the action and is applicable to different levels of representational organization. (shrink)

Policy-makers must sometimes choose between an alternative which has somewhat lower expected value for each person, but which will substantially improve the outcomes of the worst off, or an alternative which has somewhat higher expected value for each person, but which will leave those who end up worst off substantially less well off. The popular ex ante Pareto principle requires the choice of the alternative with higher expected utility for each. We argue that ex ante Pareto ought to be rejected (...) because it conflicts with the requirement that, when possible, one ought to decide as one would with full information. We apply our argument in an analysis of US policy on screening for breast cancer. -/- . (shrink)

La critique littéraire est-elle vouée par nature et fonction à rester un « discours second » entièrement subordonné à un texte premier qui peut seul prétendre à la dignité d’un discours créateur? L’interprète peut-il se départir de toute déférence à l’égard des décisions de l’auteur pour les regarder comme des choix parmi d’autres, de fragiles options ou des arrêts toujours révisables? Peut-on concevoir une forme de critique authentiquement créatrice qui s’émanciperait du respect attaché à la lettre du texte pour entrer (...) dans l’élan dont l’œuvre est le produit, en tentant par exemple de lui offrir quelque supplément, voire en l’imaginant tout à fait autrement? Les auteurs critiques ici réunis s’accordent à donner priorité au possible sur le réel, en traquant dans les œuvres déjà faites la trace de scénarios abandonnés ou de livres qui restent à écrire. Renouant parfois avec des convictions très anciennes – celles de la tradition rhétorique ou de la philologie – ils jettent les bases d’une théorie des textes possibles qui invite à aimer dans les grands textes littéraires non seulement le passé dont ils viennent mais aussi le futur qu’ils recèlent en puissance.

Aborder Montaigne en pédagogue du jugement, c'est renouveler une lecture qui permit à Gabriel Compayré, Émile Faguet ou Pierre Villey de recommander la lecture d'un auteur réputé sceptique en dépit de son scepticisme. Comment bien juger? La connaissance des règles et l'aptitude à raisonner ne suffisent pas pour faire un bon jugement. En se confiant courageusement et lucidement à son jugement personnel, Montaigne apprend à penser en situation d'incertitude, tout en renouant avec l'expérience et les grands auteurs.

Dieser Text geht der Frage nach, ob und, wenn ja, inwieweit sich Gedankenexperimente in der praktischen Philosophie in ihrer Struktur und ihrer epistemischen Signifikanz von Gedankenexperimenten in der theoretischen Philosophie oder in den Naturwissenschaften unterscheiden. Anhand einer allgemeinen Strukturanalyse von Gedankenexperimenten wird dabei aufgezeigt, dass bei Gedankenexperimenten in der praktischen Philosophie zwar häufig die angemessene Bewertung eines zugrunde gelegten Szenarios im Zentrum steht und nicht, wie zum Beispiel in theoretischen Philosophie oft, dessen angemessene Beschreibung, dass dieser Unterschied aber kaum Auswirkungen (...) hat auf die prinzipielle Anwendbarkeit – abgesehen von einer bisher übersehenen Konsequenz: Man darf in einem Gedankenexperiment nicht annehmen, dass moralische, ästhetische oder entscheidungstheoretische Prinzipien in unterschiedlichen möglichen Welten verschieden sind. Andernfalls käme dem Gedankenexperiment keinerlei epistemische Signifikanz zu. (shrink)
