The purpose of the book is to clarify the notion of existential dependence and cognate notions, such as supervenience and the notion of an internal relation. I defend the view that such notions are best understood in terms of the concept of metaphysical grounding, i.e. the concept of one fact obtaining in virtue of other facts, where ‘in virtue of’ has a distinctively metaphysical meaning.

I assume that truth-making is to be understood in terms of grounding, and I show how, on that assumption, various general properties of truth-making follow from certain features of grounding.

L'enjeu de l'écologie n'est plus simplement d'actualité, il est urgent. Le climat change, les ressources s'épuisent, et plus le temps passe plus les sombres prédictions faites par le Club de Rome dans les années 1970 se vérifient. En conséquence, la question rencontre de plus en plus d'intérêt. Les thèses sont nombreuses, et à les lire, on ne peut se départir d'une impression de flou, voire d'éparpillement ou de contradiction. L'écologie politique est-elle progressiste? Est-elle réactionnaire? Est-elle libertaire ou autoritaire? S'agit-il d'une (...) nouvelle religion? S'agit-il du nouveau conflit central? En partant des questions clé qui ont orienté les débats autour de l'écologisme depuis son apparition dans les années 1960, Fabrice Flipo organise la discussion et relie les fils épars de l'analyse empirique et théorique. Il nous montre que l'écologie politique se définit non par la protection de l'environnement mais par une remise en cause de l'universalité du mode de vie moderne. L'écologisme est ainsi un mouvement d'emblée global, qui renverse les cadres établis de la politique. (shrink)

Recent metaphysics has turned its focus to two notions that are—as well as having a common Aristotelian pedigree—widely thought to be intimately related: grounding and essence. Yet how, exactly, the two are related remains opaque. We develop a unified and uniform account of grounding and essence, one which understands them both in terms of a generalized notion of identity examined in recent work by Fabrice Correia, Cian Dorr, Agustín Rayo, and others. We argue that the account comports with antecedently (...) plausible principles governing grounding, essence, and identity taken individually, and illuminates how the three interact. We also argue that the account compares favorably to an alternative unification of grounding and essence recently proposed by Kit Fine. (shrink)

A long-standing debate surrounds the question as to what justifies memory judgements. According to the Past Reason Theory, these judgements are justified by the reasons we had to make identical judgements in the past, whereas the Present Reason Theory claims that these justifying reasons are to be found at the time we pass the memory judgements. In this paper, I defend the original claim that, far from being exclusive, these two theories should be applied to different kinds of memory judgements. (...) The Past Reason Theory offers the most appealing account of justified propositional memory judgements, while the Present Reason Theory provides the best approach to justified episodic memory judgements. One outcome of my discussion is thus that memory is not epistemologically unified and my argument in favour of this conclusion connects with the issues of internalism, reliabilism and the basing relation.

La quatrième de couverture indique : "La création, l'émergence et la nouveauté sont des notions indispensables pour comprendre l'évolution naturelle et l'histoire culturelle. Il est toutefois bien difficile de les définir : comment en effet repenser adéquatement la nouveauté et l'émergence? Comment même les envisager, avec leurs conséquences et leurs répercussions, dans l'histoire humaine en général si la vie, la conscience et la culture forment des noeuds gordiens impossibles à défaire? Cet essai espère résoudre de tels problèmes en répertoriant les (...) contradictions et les tensions des projets naturalistes. Une autre image de l'histoire humaine surgit alors, plus surprenante que celle imposée par la phénoménologie de la vie et la psychologie évolutionniste.". (shrink)

In a nutshell, semantic antirealism is the doctrine that if a statement is true, then it must be possible, at least in principle, to determine that it is true. Consider the particular case of self-ascriptions of attitudes such as beliefs, desires and intentions, i.e. statements of the form "I φ [that] p", where φ ranges over propositional attitude verbs and p provides the content of whatever is φd by the self-ascriber. Should we be semantic antirealists about these when the putative (...) bearer of the attitude is the only individual who may retrieve a warrant in favour of his φing that p? We can't provide an answer to the question unless we're clear about (i) whether or not the "at least in principle" clause is too weak, and (ii) what the right construal of positive introspection should look like. 2 Thus two issues: strict finitism on the one hand and the phenomenological nature of introspective warrants on the other. I shall argue that recent views defended by Peacocke and Pryor are found wanting with respect to both. (shrink)

According to semantic antirealism, intuitionistic logic satisfies the requirement that truth should be constrained by provability in principle. Some philosophers have argued that semantic antirealism must be committed to effective provability and that the commitment leads to a stronger kind of logical revisionism exemplified by substructural logics. I shall take into account two different kinds of reply. The first is concerned with meaning per se and grasp or fixing of meaning. It rests on the idea that if we have a (...) method which may be used over some surveyable range, we have determined a way of applying the method everywhere in principle, and that this is enough as far as fixing or grasping meaning is concerned. The second concerns two radical antirealist principles disqualifying structural rules: Token Preservation and Preservation of Local Feasibility. Against criticisms, I shall argue that conceptual support may be provided for both. The main point in this debate is that there is a decisive difference between the rejection of classical logic via the curbing of the epistemic idealizations embedded in structural rules and the rejection of classical logic via the intuitionistic criticism of invalid introduction and elimination rules. It will be explained why the second rejection is stronger than the former. (shrink)

I offer and defend an account of real definitions. I put forward two versions of the account, one formulated in terms of the notion of generalised identity and of a suitable notion of grounding, and the other one formulated in terms of the former notion and of a suitable notion of comparative joint-carvingness. Given a plausible assumption, and turn out to be equivalent. I give a sketch of a unified account of the three notions involved in and from which the (...) assumption can be derived. (shrink)

The evaluations involved in shame are, intuitively at least, of many different sorts. One feels ashamed when seen by others doing something one would prefer doing alone (social shame). One is ashamed because of one’s ugly nose (shame about permanent traits). One feels ashamed of one’s dishonest behavior (moral shame), etc. The variety of evaluations in shame is striking; and it is even more so if one takes a cross-cultural perspective on this emotion. So the difficulty – the “unity problem” (...) of shame- turns out to be the following: is there a common trait shared by all shame evaluations that will allow us to differentiate these evaluations from those that feature in other negative self-reflexive emotions like anger at oneself or self disappointment? Some progress is perhaps accomplished if we say that, in shame, a given trait or behavior is evaluated as degrading or as revealing one’s lack of worth. Still, even if we agree with this last claim, truth is that these answers are less illuminating than we might wish. A theory of shame should surely further elucidate the aspect of one’s identity relevant for shame, namely, the self of shame. In this connexion, philosophers have referred to “self-esteem,” “self-respect” or the “social self,” significantly disagreeing thus on which aspect of one’s identity is at stake in shame. After critically discussing the different solutions to the problem, we offer our own. Shame, we claim, consists in an awareness of a distinctive inability to discharge a commitment that goes with holding self-relevant values. This conception solves the unity problem while illuminating other aspects of this emotion. (shrink)

'Ontological dependence' is a term of philosophical jargon which stands for a rich family of properties and relations, often taken to be among the most fundamental ontological properties and relations. Notions of ontological dependence are usually thought of as 'carving reality at its ontological joints', and as marking certain forms of ontological 'non-self-sufficiency'. The use of notions of dependence goes back as far as Aristotle's characterization of substances, and these notions are still widely used to characterize other concepts and to (...) formulate metaphysical claims. This paper first gives an overview of the varieties of these notions, and then discusses some of their main applications. (shrink)

Si un philosophe a fondé son oeuvre sur la conscience historique, c'est bien Raymond Aron. Le rapprochement entre Aron et la post-modernité pourrait surprendre. Il en va tout autrement si l'on considère la conception historique de la post-modernité : celle-ci suit logiquement les Temps Modernes. Elle comprend alors les deux siècles de tensions idéologiques qui ont suivi 1789, jusqu'à la chute du mur de Berlin. Raymond Aron a commenté et pensé les convulsions apocalyptiques du dernier siècle post-moderne. D'où l'idée de (...) le considérer sous plusieurs angles : face au basculement du monde, la critique des idéologies (D. Steinmetz-Jenkins), la théorie des relations internationales (O. Rosenboim), son jugement sur la "tragédie algérienne" (O. Dard). Mais Aron est aussi sensible aux permanences, à ce qui ne bascule pas : c'est un penseur de la nation et des identités régionales, qui s'interroge sur sa propre judéité (G. De Ligio). La philosophie d'Aron, où l'historien est créateur et incarné, présente une analogie avec la théologie chrétienne : Pierre Manent décrit la relation d'Aron au christianisme. Enfin, Aron reste un intellectuel tout engagé dans la défense de la liberté, ce qu'explorent deux contributions : sur ce qu'il doit au libéralisme d'Edmund Burke (M. Oppermann), et sur sa recherche d'une stratégie modérée chez l'historien Hans Delbrück (J. Mouric). Encadrées par l'introduction de Fabrice Bouthillon et la conclusion de Pascal David, ces études esquissent les traits d'une pensée subtile : sceptique contre le dogmatisme des idéologies totalitaires, mais non relativiste, attachée à l'historicité, sans tomber dans le déterminisme historique. Ce volume est issu de la journée d'études du 18 novembre 2014 à l'Université de Bretagne occidentale à Brest."--Page 4 of cover. (shrink)

Some of the most eminent and enduring philosophical questions concern matters of priority: what is prior to what? What 'grounds' what? Is, for instance, matter prior to mind? Recently, a vivid debate has arisen about how such questions have to be understood. Can the relevant notion or notions of priority be spelled out? And how do they relate to other metaphysical notions, such as modality, truth-making or essence? This volume of new essays, by leading figures in contemporary metaphysics, is the (...) first to address and investigate the metaphysical idea that certain facts are grounded in other facts. An introduction introduces and surveys the debate, examining its history as well as its central systematic aspects. The volume will be of wide interest to students and scholars of metaphysics.

La différence entre les êtres humains et les autres espèces n'est-elle vraiment qu'une différence de complexité? Ne ressemble-t-elle pas plutôt à ce que l'on nomme en linguistique une nuance? Car un terme proche d'un autre ne signifie pourtant pas la même chose que lui de manière plus complexe. Il suggère tout autre chose malgré des points de recoupement. Il convient de le démontrer en dénonçant une représentation trop caricaturale de l'être humain.

The aim of this thesis is to examine the concept of virtue ethics in Stanley Hauerwas's understanding of virtue and delineate how that contributes to his ethical reasoning and his comprehension of medical ethics. The first chapter focuses on the shift that occurred in moral theory under the stance of the Enlightenment that eroded the traditional idea of morality as the formation of the self, allowing space for new concepts that dismissed the importance of the agent in the ethical task (...) of seeking the good. In the second chapter, the three main ideas that make up Hauerwas' ethical theory are examined with a particular attention to the importance of agency in moral life. The third chapter describes how Hauerwas' medical ethics, informed by his moral theory based on character, vision, and narrative, is relevant to medical ethics. Hauerwas argues that because medicine is a form of human activity with internal goods and standards of excellence intrinsic to its practice, it requires taking into account the notion of agency in the healing relationship. Finally, in the last chapter the specific religious discourse of Hauerwas' ethics is discussed in relation to secular medical ethics. In other words, this thesis raises the question of whether the reduction of medical ethics to a set of principles, as it is mostly the case today, represents a suitable picture of the reality of moral life in medicine.

Cet ouvrage constitue un contraste épistémologique entre différentes reconstructions rationnelles et pose le problème des fondements de la rationalité scientifique. A partir de la pensée du philosophe des mathématiques et des sciences hongrois Imré Lakatos, il vise à démontrer que la science est formulée par des principes rationnels et logiques. La vérifiabilité selon le Cercle de Vienne et la falifabilité d'après Popper en constituent des exemples typiquement justifiables pour distinguer la science de la pseudoscience et rejeter les croyances envisagées par (...) l'épistémologie de la découverte soutenue par Thomas Kuhn et Polanyi. La critique interprétative que Lakatos construit contre le poppérisme et/ou le falsificationnisme amplifie méthodologiquement le sens de la rationalité, en ce sens que Lakatos en arrive systématiquement à implémenter l'intelligence de falsifier le falsificationnisme poppérien. La compréhension d'une telle épistémologie de l'interprétation amène à constater que la structuration " méthodologique a des programmes de recherche est composée des voies heuristiques à éviter et à suivre. Ainsi, l'heuristique négative caractérisant le noyau dur du programme en constitue une réduction et fermeture méthodologique, tandis que le glacis protecteur et l'heuristique positive ouvrent et amplifient la recherche scientifique. Aussi, une étude historiographique des programmes est ici envisagée comme l'attestation de la jointure épistémologique de l'histoire et de la philosophie des sciences. (shrink)

Realism is the claim that truth may transcend all possible verification. The familiar Dummettian argument against that modal claim is that there is no way to manifest an understanding of it in actual linguistic practice. The Dummettian anti-realist's provisional conclusion is that the modal claim must be false. ;The attack on truth-conditional semantics and on the principle of bivalence are familiar ingredients of the anti-realist negative programme. I agree that, whether mathematical formulae or ordinary sentences in the past tense are (...) concerned, we cannot manifest a knowledge of the truth-conditions of particular instances of 'It is possible that ' by deciding their truth. There is nevertheless a way to argue in favour of specific instances of the modal claim when s is a sentence in the past tense. The proposed argument does not appeal to the recognitional abilities which, in the standard anti-realist perspective, constitute grasp of meaning. It does not commit one to the endorsement of the principle of bivalence, although the principle implies the modal claim. ;Our understanding of the workings of nature, whether grounded on scientific theories or on common sense, implies the modal claim. Since we are only contingently connected to the evidence pro or con past events and since the existence of evidence is itself a contingent matter, sentences which say that those events occurred could be true whether or not we can, at any point in time, detect that they are true. The possibility that truths about past facts transcend all possible verification is a purely natural possibility, grounded on what we know of the workings of nature. ;This implies that decidable statements in the past tense are not immune to the realism vs. anti-realism debate. Although they do not transcend verifiability, they could transcend whatever our recognitional abilities, no matter how extended, would allow us to establish at any point in time, either in the past, right now, or in an indefinitely extensible future.

La théorie du choix rationnel se déploie dans deux directions complémentaires. Son application contextuelle et extensive sature puis déborde le domaine circonscrit de l’économie substantielle pour finalement identifier décision économique et choix humain. Son perfectionnement structurel et intensif dépasse le cadre de base du choix certain pour traiter les formes exogène et endogène d’incertitude. Ces deux avancées, l’une thématique et l’autre analytique, se combinent pour assurer la diffusion générale de l’exercice du choix rationnel. Au-delà de son intérêt et de ses (...) accomplissements, cette entreprise d’économicisation universelle se heurte à des limites dans les deux directions de son développement. Contextuellement, la logique du choix économique est dans l’incapacité d’appréhender la morale déontologique ou la rationalité axiologique. Et structurellement, la logistique du choix rationnel n’est pas opérationnelle face à un environnement radicalement incertain et en situation de face-à-face intersubjectif avec autrui. (shrink)

This paper suggests that the enactive approach to ethics could benefit from engaging a dialogue with the phenomenology of Emmanuel Levinas, a philosopher who has given ethics a decisive role in the understanding of our social life. Taking the enactive approach of Colombetti and Torrance as a starting point, we show how Levinas’ philosophy, with the key notions of face, otherness, and responsibility among others can complement and enrich the enactive view of ethics. Specifically, we argue that Levinas can provide, (...) on the one hand, a phenomenological characterisation of ethics itself, of its nature and fundamental meaning, and on the other, an account of how sociality, affectivity and embodiment, as presented in Colombetti and Torrance’s work, combine to bring about the ethical experience. However, we also point out that introducing Levinas to the enactive approach could be challenging. It is not obvious how sense-making and value-making, as centred on the precariousness and potential death of the subject, would account for the ethical experience as grounded on the precariousness and potential death of the other.

Grounding is a hyperintensional notion: necessarily equivalent sentences need not be equivalent from a ground-theoretic perspective. How fine-grained, exactly, is grounding? There is a striking lack of consensus on this question. In this chapter, I try to systematize and review the main options that have been put forward in the literature. For reasons that have to do with both naturalness and convenience, I for the most part take the question to be about what is sometimes called, following Kit Fine’s (2012a) (...) terminology, strict full grounding, and I take for granted a conception of grounding as a relation that is many-to-one and non-factive. I discuss the consequences of making alternative assumptions only in the very last section. (shrink)

English summary: Ruyer argued that metaphysics spanned the spaces or gaps of knowledge that escaped from scientific teaching. Attentive to the latest scientific advancements, Ruyer produced a monism that placed a finalism attached to existing forms at the center of the universe, creating an original philosophical theology. After a brief biography, this book presents Ruyers work and thought, his principal texts in which he emerges as one of the most important thinkers of the twentieth century. French description: Il y deux (...) manieres de se convaincre qu'on peut retirer une connaissance profonde de l'etude des sciences de la nature. Ou l'on croit que les sciences decrivent avec exactitude l'univers (et l'homme lui-meme). Ou l'on tient avec Ruyer qu'en suivant mot a mot, et pas a pas, les enseignements des sciences, on enjambe des espaces de connaissance qui leur echappent et qui sont l'objet de la metaphysique. Attentif aux dernieres avancees du savoir, Ruyer decouvre la possibilite de retourner le materialisme et de produire un monisme qui place au centre de l'univers, non plus la matiere, mais le finalisme attache aux formes existantes. Cette metaphysique qui est exposee notamment dans le Neo-finalisme, rejette le dualisme, se passe du sujet cartesien et aboutit a une theologie originale. Apres une breve biographie de Ruyer, le present ouvrage etudie les constantes et les evolutions de sa pensee, puis analyse ses oeuvres principales, ou l'on reconnaitra sans peine un des penseurs majeurs du XXe siecle.

L'ouvrage invite à penser l'épistémologie non classique des mathématiques comme une construction épistémique des mathématiques quasi empirique qu'Imré Lakatos a réalisé au moyen des présupposés ontologiques (comme la redécouverte du temps, le passage du déterminisme à l'indéterminisme, etc.) et qu'il réussit grâce à l'implémentation du principe de complexité dialectique de l'esprit mathématique. L'auteur étudie la thèse selon laquelle, depuis le début du XXe siècle, la science est aussi bien objective que subjective. Et c'est à partir de celle-ci que le principe (...) de "la complexité dialectique de l'esprit mathématique" est mis au jour pour dévoiler le constructivisme de Lakatos. (shrink)

This monograph is a detailed study, and systematic defence, of the Growing Block Theory of time (GBT), first conceived by C.D. Broad. The book offers a coherent, logically perspicuous and ideologically lean formulation of GBT, defends it against the most notorious objections to be found in the extant philosophical literature, and shows how it can be derived from a more general theory, consistent with relativistic spacetime, on the pre-relativistic assumption of an absolute and total temporal order. -/- The authors devise (...) axiomatizations of GBT and its competitors which, against the backdrop of a shared quantified tense logic, significantly improves the prospects of their comparative assessment. Importantly, neither of these axiomatizations involves commitment to properties of presentness, pastness or futurity. The authors proceed to address, and defuse, a number of objections that have been marshaled against GBT, including the so-called epistemic objection according to which the theory invites skepticism about our temporal location. The challenge posed by relativistic physics is met head-on, by replacing claims about temporal variation by claims about variation across spacetime. -/- The book aims to achieve the greatest possible rigor. The background logic is set out in detail, as are the principles governing the notions of precedence and temporal location. The authors likewise devise a novel spacetime logic suited for the articulation, and comparative assessment, of relativistic theories of time. The book comes with three technical appendices which include soundness and completeness proofs for the systems corresponding to GBT and its competitors, in both their pre-relativistic and relativistic forms. -/- The book is primarily directed at researchers and graduate students working on the philosophy of time or temporal logic, but is of interest to metaphysicians and philosophical logicians more generally.

A possible world semantics for standard modal languages is presented, where the valuation functions are allowed to be partial, the truth--functional connectives are interpreted according to weak Kleene matrices, and the necessity operator is given a "weak" interpretation. Completeness and incompleteness results for some (axiomatic) systems are then established. Extensions of these modal logics in which figure "statability" operators are also examined.

This volume features essays about and by Paul Benacerraf, whose ideas have circulated in the philosophical community since the early nineteen sixties, shaping key areas in the philosophy of mathematics, the philosophy of language, the philosophy of logic, and epistemology. The book started as a worskhop held in Paris at the Collège de France in May 2012 with the participation of Paul Benacerraf. The introduction addresses the methodological point of the legitimate use of so-called “Princess Margaret Premises” in drawing philosophical (...) conclusions from Gödel’s first incompleteness theorem. The book is then divided into three sections. The first is devoted to an assessment of the improved version of the original dilemma of “Mathematical Truth” due to Hartry Field: the challenge to the platonist is now to explain the reliability of our mathematical beliefs given the very subject matter of mathematics, either pure or applied. The second addresses the issue of the ontological status of numbers: Frege’s logicism, fictionalism, structuralism, and Bourbaki’s theory of structures are called up for an appraisal of Benacerraf’s negative conclusions of “What Numbers Could Not Be.” The third is devoted to supertasks and bears witness to the unique standing of Benacerraf’s first publication: “Tasks, Super-Tasks, and Modern Eleatics” in debates on Zeno’s paradox and associated paradoxes, infinitary mathematics, and constructivism and finitism in the philosophy of mathematics. Two yet unpublished essays by Benacerraf have been included in the volume: an early version of “Mathematical Truth” from 1968 and an essay on “What Numbers Could Not Be” from the mid 1970’s. A complete chronological bibliography of Benacerraf’s work to 2016 is provided.Essays by Jody Azzouni, Paul Benacerraf, Justin Clarke-Doane, Sébastien Gandon, Brice Halimi, Jon Pérez Laraudogoitia, Mary Leng, Antonio Leòn-Sànchez and Ana Leòn-Mejía, Marco Panza, Fabrice Pataut, Philippe de Rouilhan, Andrea Sereni, and Stewart Shapiro.

It is often claimed that emotions are linked to formal objects. But what are formal objects? What roles do they play? According to some philosophers, formal objects are axiological properties which individuate emotions, make them intelligible and give their correctness conditions. In this paper, I evaluate these claims in order to answer the above questions. I first give reasons to doubt the thesis that formal objects individuate emotions. Second, I distinguish different ways in which emotions are intelligible and argue that (...) philosophers are wrong in claiming that emotions only make sense when they are based on prior sources of axiological information. Third, I investigate how issues of intelligibility connect with the correctness conditions of emotions. I defend a theory according to which emotions do not respond to axiological information, but to non-axiological reasons. According to this theory, we can allocate fundamental roles to the formal objects of emotions while dispensing with the problematic features of other theories. (shrink)

Merleau-Ponty, malgre ce que peut suggerer une lecture trop rapide, a refuse de placer son entreprise sous le signe de l'anti-metaphysique. Certes, il a tenu compte des critiques anterieures adressees a la metaphysique, cependant il occupe une position originale et singuliere dans le champ philosophique contemporain.

Ruyer et Bachelard ont en commun de concevoir le travail de la philosophie comme essentiellement lié à la science. Toutefois, alors que Bachelard s’en tient à des positions épistémologiques, Ruyer entend tirer des conclusions métaphysiques des résultats de la physique contemporaine. Il expose ses vues à l’occasion de deux comptes rendus qu’il fait des écrits de Bachelard. Selon Ruyer, les activités structurantes originales qui caractérisent les atomes et les molécules autorisent à les comparer aux êtres biologiques des étages supérieurs et (...) à défendre une vision panpsychiste du réel. L’imagination métaphysique peut alors proposer ce que Ruyer appelle une « lecture du monde » qui en donne une vision unifiée et intensifiée.

There are several ways of conceiving objectivity -- scientific objectivity in particular -- and, accordingly, several ways of defending or attacking particular construals of it. According to one conception sometimes labelled "realism", objectivity in science is a semantic, modal and metaphysical notion: a scientific theory is objective insofar as it tells the truth about the way the world is independently of its epistemic accessibility to us. So, for instance, the Newtonian theory of gravition is objective insofar as it tells the (...) truth about the motion of particles submitted to gravitational forces. What it tells us, the realist contends, holds or is the case whether or not the physical world is accessible to us. The conception is semantic insofar as the notion of truth is involved, modal insofar as the conception of the possibility of a mind-independent natural world is involved and metaphysical insofar as a conception of a certain way the world is is involved. Philosophers as diverse as Berkeley, Kant and Dummett's antirealist will then ask: if this were the case, how could we know anything about it? How could we even form a bona fide conception of its possibility? (shrink)

As far as logic is concerned, the conclusion of Michael Dummett's manifestability argument is that intuitionistic logic, as first developed by Heyting, satisfies the semantic requirements of antirealism. The argument may be roughly sketched as follows: since we cannot manifest a grasp of possibly justification-transcendent truth conditions, we must countenance conditions which are such that, at least in principle and by the very nature of the case, we are able to recognize that they are satisfied whenever they are. Intuitionistic logic (...) satisfies the semantic requirement that we should either eschew the notion of truth altogether and replace it by provability in principle, or constrain it by provability in principle (Dummett [1973] 1978). (Handout: 1-5). Some philosophers have argued that the traditional antirealist desideratum of decidability in principle is too weak, so that semantic antirealism properly construed must be committed to effective decidability. As such, it either leads to strict finitism (Wright [1982] 1993) [Handout: 6] or to a much stronger kind of logical revisionism than the one considered by intuitionists (whether or not they accept the manifestability argument): substructural logics, and in particular linear logics, rather than intuitionistic logic, satisfy the semantic requirements of strict antirealism (Dubucs and Marion 2004) [Handout: 8-9]. I shall develop two different kinds of replies. The first is concerned with the notion of meaning per se and looks to strict finitism directly, although not on the ground that it would provide a correct way of dealing with Soritic-type paradoxes (the original and primary focus of discussion in Wright [1982] 1993). The second is concerned with the justification of structural and logical rules in a natural deduction system à la Gentzen. It will deal in particular with the criticism of the structural rules of Weakening and Contraction [Handout: 10 and 11]. The first kind of reply, which Dummett has partially taken into consideration, is that if we jettison the effectively vs. in principle distinction, as applied to manifestability-type arguments, we end up with an unsatisfactory explanation of how the meaning of statements covering the practically unsurveyable or pro tempora undecided cases is fixed. The idea is that if we have a method which may be used over some small range, we have determined a way of applying the method everywhere in principle and that this is enough as far as fixing meaning is concerned. Decidability in principle is just what we need with respect to manifestation of grasp of meaning. In this perspective, antirealism shouldn't be strict and manifestability-type arguments need not be applied as far as the strict finitist would want to [Handout: 7]. It follows that there is no reason to think that practical feasibility should be built in assertibility conditions and proofs be construed dynamically as acts in the strict antirealist's acception of that term [Handout: 8]. I shall then look at one radical antirealist principle disqualifying structural rules, namely Token Preservation, arguing against Bonnay and Cozic's criticisms of Dubucs and Marion (Bonnay and Cozic 3 2007) that some conceptual support may be provided for Token Preservation, which doesn't rely on a causal misreading of the turnstile [Handout: 13, 14]. I shall then assess the merits and limits of radical antirealism and the logic of feasible proofs with respect to the original Dummettian argument in favour of semantic antirealism (provided it has indeed revisionist implications for logic), whether the radical antirealist merely stipulates what human feasibility amounts to, or dispenses with structural rules in order to argue in favour of a curb on the epistemic idealizations they unwarrantedly embed. It will be noted here that there is a great difference, conceptually speaking, between the rejection of classical logic via the curbing of the epistemic idealizations embedded in structural rules, and the rejection of classical logic via the criticism of the introduction and elimination rules which fix the meaning of the classical constants. The kind of logical revisionism envisaged by intuitionists from Heyting on is in many respects stronger than the one envisaged by advocates of linear logic, should they ground their arguments on an endorsement of strict antirealism. The crucial case of excluded middle is telling. Because of the splitting of the constants in linear logic (Handout: 12], two distinct laws of excluded middle may be formulated (Handout: 15), but the traditional arguments of Brouwer and Heyting against the classical law yield a stronger revision than the substructural revision with its admission of these two (very) weak versions of the law. (Project: a clearer conception is needed of how the introduction and elimination rules for the logical connectives in the intuitionistic calculus depend on the structural rules which the radical antirealist wishes to reject.).

The aim of this article is to explore in a systematic way the rationality of emotions elicited when we engage with works of fiction. I first lay out the approach to the emotions on which my discussion is premised. Next, I concentrate on two facets of emotional rationality—the first pertains to the relation between emotions and the mental states on which they are based, the second to the relation between emotions and the judgements and behaviour they elicit. These observations about (...) emotional rationality are then applied to emotions elicited by works of fiction. After having distinguished several families of emotions, I concentrate on what I call blob-emotions and emotions-for. I argue that, given their nature as direct responses to a restricted range of stimuli, blob-emotions are not irrational. As regards emotions-for fictional entities, I emphasize that a subject’s rationality shows in the way her emotions-for respond to evidence. On this basis, I discard an influential reason to think that emotions-for fictional entities are irrational. Finally, I offer an argument to conclude that they are typically correct and rational.

How does metaphysical grounding interact with the truth-functions? I argue that the answer varies according to whether one has a worldly conception or a conceptual conception of grounding. I then put forward a logic of worldly grounding and give it an adequate semantic characterisation.

Contemporary philosophers are attracted by the Indispensability Claim, according to which emotions are indispensable in acquiring knowledge of some important values. The truth of this claim is often thought to depend on that of Emotional Dogmatism, the view that emotions justify evaluative judgements because they (seem to) make us aware of the relevant values. The aim of this paper is to show that the Indispensability Claim does not stand or fall with Emotional Dogmatism and that there is actually an attractive (...) alternative way of developing it. We first argue that the Indispensability Claim requires a deflationary account of the cognitive bases of emotions, which we call the Simple View and defend against a variety of criticisms. Armed with the Simple View, we show that the Indispensability Claim is made true by three roles of the emotions: they help us access the relevant evidence, provide a needed hook-up between evidence and judgement, and contribute to evaluative understanding.

La question n'est plus : 'L'écologie, pour ou contre?' Le label vert a partout remplacé le label rouge (ou bleu ciel). La question est : 'Quelle écologie?' Or il y a là un problème, et même un 'problème à cornes,' selon la formule de Nietzsche : peut-on vraiment fonder l'écologie sur la Nature, dont la notion est si ambivalente? Elle n'a pas attendu l'homme pour produire cinq extinctions massives. Laissée à elle-même, elle éteindra tout, y compris les étoiles. Par ailleurs, (...) s'il faut bien sauvegarder les espèces dans leur admirable diversité, est-ce uniquement dans un but de conservation? La seule conservation eût été la finalité de la Nature que la vie n'aurait même pas dû commencer: une pierre dès le départ était plus performante. Et si le sens du vivant ne se trouvait pas tant dans la conservation que dans l'exposition de soi--et une exposition glorieuse--, jusqu'au sacrifice? Si la Madone était plus vraie que la Méduse? Fabrice Hadjadj nous offre ici une puissante méditation sur le vivant, l'interdépendance spirituelle de l'homme et des bêtes, la relation entre écologie et eschatologie. A travers une approche à la fois philosophique et biblique, il pense une tragédie heureuse, où il ne s'agit pas de donner pour durer, mais de durer pour donner encore.. En bref, il prend le taureau par les cornes."--Page 4 of cover. (shrink)
