We present an age-structured model for erythropoiesis in which the mortality of mature cells is described empirically by a physiologically realistic probability distribution of survival times. Under some assumptions, the model can be transformed into a system of delay differential equations with both constant and distributed delays. The stability of the equilibrium of this system and possible Hopf bifurcations are described for a number of probability distributions. Physiological motivation and interpretation of our results are provided.

Pour les Anciens, l’effet de l’air sur la santé allait de soi. L’air était tenu pour la principale cause de maladie, soit par sa variation saisonnière (chaque saison ayant ses maladies propres), soit par sa nocivité intrinsèque (par exemple près de marais). On attribuait notamment à l’air les épidémies, les symptômes semblables de nombreux malades s’expliquant mieux par l’air nous entourant que par des facteurs individuels comme le régime ou l’exercice. La thérapeutique antique consistait donc souvent à compenser les effets (...) de l’air pour ajuster l’équilibre entre le corps et l’environnement. On trouve aussi de riches réflexions sur la prévention, notamment dans le domaine de l’agronomie et de l’architecture : si la stratégie principale au moment d’établir une ferme ou une nouvelle ville était d’éviter un site à l’air malsain, certaines méthodes étaient aussi proposées pour améliorer la qualité de l’air et permettre d’intégrer les installations humaines à un environnement nocif.

Le newtonisme moral, à la mode au milieu du XVIIIe siècle, n’est pas seulement une métaphore: en vertu du principe de l’unité de la nature, il postule dans la société une loi semblable à la loi des distances en physique, voire une possibilité de mesure. La même règle d’analogie (A/B = CID) sous-tend le Contrat social de Jean-Jacques Rousseau : en prolongement des métaphores classiques de l’horloge, la définition du gouvernement reproduit l’agencement d’une montre, jusque dans les calculs de (...) proportion qui servent aux horlogers à former le rouage. De même, dans la Théorie des sentiments moraux, Adam Smith se sert de la vieille métaphore de I’ oeil de lesprit et des notions plus modernes de la perspective optique pour agencer en système lensemble des interactions possibles entre deux personnes – hormis l’intérêt – en faisant varier la distance imaginaire entre les protagonistes selon les passions exprimées et leur intensité. Il est important de restituer ces transferts et ces controverses pour comprendre les enjeux fondamentaux de la sociologie au XIXe siècle. (shrink)

Modern social and political thought has approached the questions of politics, law, and citizenship from the vantage point of a fundamental divide between the occidental and oriental, or archaic and modern, institutions. This article creates a concept, the gift of law, by staging two gift-giving practices as two historical moments: Greek euergetism and Ottoman waqf. While it is indebted to Mauss, our articulation of the gift of law also owes to the critical interventions of Jacques Derrida and Pierre Bourdieu, (...) who emphasized non-voluntaristic and non-calculative aspects of the gift. We argue that both euergetism and the waqf enabled and substantiated legal subjectivities that allocated rights and obligations. Those gift-giving practices establish relationships between various groups and legal authorities that were crucial in the formation of cities as spaces of government, for both citizens and non-citizens alike. With the concept ‘gift of law’, categories ‘oriental’ and ‘occidental’ become problematic. (shrink)

Philosophe et penseur du politique, intellectuel marxiste et militant communiste, enseignant, directeur de collection... : à travers le rayonnement de son oeuvre et de sa personne, Louis Althusser a renouvelé la théorie politique et la philosophie de l'histoire, de Machiavel à Marx. Parmi ses contemporains, Michel Foucault exhorte : " Ouvrez les livres d'Althusser! ", Jacques Derrida évoque " la force rayonnante et provocante de sa pensée ", Gilles Deleuze salue l'" Althusser's Band ", et pour Roland Barthes, " (...) le seul modèle acceptable de la science est celui mis au jour par les études d'Althusser sur Marx ". Aliocha Wald Lasowski converse avec vingt écrivains et philosophes qui ont lu, rencontré, parfois travaillé avec Althusser, quand ils n'ont pas fait partie de ses proches. Où l'on mesure à quel point la pensée d'Althusser demeure d'une actualité brûlante. (shrink)

A neighborhood in a US city seems to present a possibly unique exception to empirical generalizations and explanations of urban decline and occasional rehabilitation. Resisting decline, gentrification, and outside interests and actors, the neighborhood generated a subculture created by working class artists. As a valuable occasion for revising urban social theory, this essay draws on the work of Howard S. Becker, Pierre Bourdieu, Henri Lefebvre, Jacques Rancière, and Georg Simmel, among others. It relies on ethnographic method for its empirical (...) findings. (shrink)

Anyone familiar with contemporary French culture could not fail to notice that, in the field of ideas, history and the philosophy of history occupy in France a more central place than in England or North America. The work and concerns—including the methodological concerns—of historians like Marc Bloch, Fernand Braudel and the Annalistes, Georges Lefebvre, Emmanuel Le Roy Ladurie, Michel de Certeau, Jacques Le Goff and Francois Furet, are known, discussed and taken on board by most French intellectuals and academics.

We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

One of Jacques Derrida’s richest and most provocative works, Life Death challenges and deconstructs one of the most deeply rooted dichotomies of Western thought: life and death. Here Derrida rethinks the traditional philosophical understanding of the relationship between life and death, undertaking multidisciplinary analyses of a range of topics, including philosophy, linguistics, and the life sciences. In seeking to understand the relationship between life and death, he engages in close readings of Freudian psychoanalysis, the philosophy of Nietzsche and Heidegger, (...) French geneticist François Jacob, and epistemologist Georges Canguilhem. Derrida gave his “Life Death” seminar over fourteen sessions between 1975 and 1976 at the École normale supérieure in Paris as part of the preparation for students studying for the agrégation, a notoriously competitive qualifying exam. The theme for the exam that year was “Life and Death,” but Derrida made a critical modification to the title by dropping the coordinating conjunction. The resulting title of Life Death poses a philosophical question about the close relationship between life and death. Derrida argues that death must be considered neither as the opposite of life nor as the truth or fulfillment of it, but rather as that which both limits life and makes it possible. Through these captivating sessions, Derrida thus not only questions traditional understandings of the relationship between life and death, but also ultimately develops a new way of thinking about what he calls “life death.”.

This collection of essays and interviews, some previously unpublished and almost all of which appear in English for the first time, encompasses the political and ethical thinking of Jacques Derrida over thirty years. Passionate, rigorous, beautifully argued, wide-ranging, the texts shed an entirely new light on his work and will be welcomed by scholars in many disciplines--politics, philosophy, history, cultural studies, literature, and a range of interdisciplinary programs. Derrida's arguments vary in their responsiveness to given political questions--sometimes they are (...) vivid polemics on behalf of a position or figure, sometimes they are reflective analyses of a philosophical problem. They are united by the recurrent question of political decision or responsibility and the insistence that the apparent simplicity or programmatic character of political decision is in fact a profound avoidance of the political. This volume testifies to the possibility and the necessity of a philosophical politics. Negotiations assembles some of the most telling examples of the intrinsic relationship, so often affirmed by Derrida in more abstract philosophical terms, between deconstructive reading practices and what is called the "political"--more precisely, politics in an almost down-to-earth, pragmatic, and commonsense use of the word. Among the many subjects covered in the book are: the death penalty in the United States, the civil war in Algeria, globalization and cosmopolitanism, the American Declaration of Independence, Jean-Paul Sartre, the value of objectivity, politics and friendship, and the relationship between deconstruction and actuality.

Is knowledge the epistemic norm of action and assertion? Gettier and justified-false-belief cases have been raised as counterexamples to the necessity direction of that claim. Most knowledge normers reply by distinguishing permissibility from excusability. An important objection to this move, however, is that it requires a still lacking view of epistemic excuses sufficiently general to cover all the cases, correctly relating the supposed excuse to the subject's cognitive life, and not collapsing into an account of the fundamental normative standard (see (...) Gerken 2017). In this paper, I rely on independent work in epistemology and cognitive science to suggest a novel account of epistemic excuses in terms of epistemic feelings. In contrast to other existing accounts, this account is immune from the above objection and can thus be used to rescue the knowledge norm. (shrink)

A translation of the Écrits logiques, edited by Jean Van Heijenoort, published in 1968.

Distinguer pour unir, ou Les degres du savoir was first published in 1932 by Jacques Maritain. In this new translation of The Degrees of Knowledge, Ralph McInerny attempts a more careful expression of Maritain's original masterpiece than previous translations. Maritain proposes a hierarchy of the forms of knowledge by discussing the degrees of rational and suprarational understanding. Nine appendices, some longer than the chapters of the book, advance Maritain's thought, often by taking on criticism of earlier editions of the (...) work. Rightly called Maritain's cardinal work, The Degrees of Knowledge is a magnificent and sagacious achievement. Jacques Maritain's masterpiece proposes a hierarchy of forms of knowledge that culminate in mystical experience and wisdom, which is a gift of the Holy Ghost. Maritain argues that the intellectual life is meant to be complemented by the spiritual life and should culminate in sanctity. (shrink)

A certain number of cases suggest that our willingness to ascribe “knowledge” can be influenced by practical factors. For revisionary proposals, they indicate that the truth‐values of “knowledge” ascriptions vary with practical factors. For conservative proposals, on the contrary, nothing surprising is happening. Standard pragmatic approaches appeal to pragmatic implicatures and psychological approaches to the idea that belief formation is influenced by practical factors. Conservative proposals have not yet offered a fully satisfactory explanation, though. In this article, I introduce and (...) defend a third conservative proposal which I call “Refined Invariantism”. The two main claims of this proposal are that (1) we should distinguish between high stakes cases in which the subject does not believe (that he knows) the target proposition and those in which he believes (that he knows) the target proposition and that (2) we should adopt a psychological treatment for the first kind of case and a pragmatic treatment based on the epistemic standards for appropriate assertion and action for the second kind of case. I argue that this new combined approach avoids the main pitfalls of its two conservative rivals and that it gives new life to the generality objection levelled against revisionary views. (shrink)

. Fresh evidence from Free Choice Items (FCIs) in French question the current perception of the class. The role of some standard distinctions found in the literature is weakened or put in a new perspective. The distinction between universal and existential is no longer an intrinsic property of FCIs. Similarly, the opposition between variation-based vs intension-based analyses is relativized. We show that the regime of free choiceness can be characterized by an abstract constraint, that we call Non-Individuation (NI), and which (...) can be satisfied in different ways that match current distinctions. NI says that the information conveyed by a sentence containing a FCI should not be reducible to a referential situation, that is a situation in which particular individuals satisfy the sentence in the current world. The widely used resource of modal variation becomes a particular scenario of free-choiceness, not its essence. In fact, we show that under certain conditions, FCIs can occur in episodic, non-modal sentences, a fact that NI can accommodate. We also discuss more fine-grained aspects of the semantics of FCIs, such as their emotional colour.

This collection makes available in English twelve papers by the distinguished French scholar Professor Jacques Brunschwig. The essays deal with problems arising in the texts and doctrines of the three major philosophical schools of the Hellenistic period - Epicureanism, Stoicism and Scepticism. The author's strategy is to focus on some specific problem and then to enlarge the conclusion of his discussion so as to reformulate or reassess some more important issue. The main subjects tackled are: problems in Epicurean cosmology (...) and linguistic theory; aspects of Stoic logic, ontology and theology; the history of Scepticism; and analysis of some of the conceptual tools used by the Sceptics in their anti-dogmatic arguments.

Among the main reactions to scepticism, fallibilism is certainly the most popular nowadays. However, fallibilism faces a very strong and well-known objection. It has to grant that concessive knowledge attributions—assertions of the form “I know that p but it might be that not p”—can be true. Yet, these assertions plainly sound incoherent. Fallibilists have proposed to explain this incoherence pragmatically. The main proponents of this approach appeal to Gricean implicatures (Rysiew in Noûs 35(4):477514, 2001; Dougherty and Rysiew in Philos Phenomenol (...) Res 78(1):123132, 2009; Dougherty and Rysiew in Synthese 181(3):395403, 2011). Very recently, some philosophers have observed that fallibilists can also explain this apparent incoherence pragmatically if they embrace a (context-sensitive) certainty norm for assertion (Petersen in Synthese 196(11):4691–4710, 2019; Beddor in Philos Impr 20(8), 2020; Vollet in Dialectica 74:3, 2020). In this paper, I argue for the superiority of this latter explanation over its older rivals. (shrink)

Jacques Maritain's An Introduction to Philosophy was first published in 1931. Since then, this book has stood the test of time as a clear guide to what philosophy is and how to philosophize. Inspired by the Thomistic Revival called for by Leo XIII, Maritain relies heavily on Aristotle and St. Thomas Aquinas to shape a philosophy that, far from sectarian theology in disguise, is driven by reason and engages the modern world. Re-released as part of the Sheed & Ward (...) Classic series, An Introduction to Philosophy is sure to enliven the minds of students and general readers for years to come. From the new introduction by Ralph McInerny: You are about to read a magnificent introduction not only to a kind of philosophy but to philosophizing itself. Jacques Maritain was a relatively young man when he wrote this book, but his effort is one that attracts any philosopher more and more as he grows older. However odd and unusual what he says becomes, the philosopher yearns to show how even the most abstruse claims can be put into relation with what the reader already knows. That, in its essence, is what teaching is. In this book, the reader will find a wise and certain guide into philosophizing as such. And, in the end, he will find that what he reads is really only a refinement and development of what he and everybody else already knew. (shrink)

A certain number of philosophers are attracted to the idea that knowledge is the epistemic norm of practical reasoning in the sense that it is epistemically appropriate to rely on p in one’s practical reasoning if and only if one knows that p. A well-known objection to the sufficiency direction of that claim is that there are cases in which a subject supposedly knows that p and yet should not rely on p. In light of the distinction between sufficient and (...) insufficient reasons, some philosophers contend that these cases are inconclusive. In this paper, I argue that this insufficient reason manoeuvre is defective because it either misconstrues the relevant cases or is at odds with strong intuitions about how we (should) reason. I then put forward further considerations relative to the instability of some pieces of reasoning and show how they can be explained by a certainty norm for practical reasoning. (shrink)

The paper presents the notion of “Spirit of Nature” in Henry More and describes its position within More’s philosophical system. Through a thorough analysis, it tries to show in what respects it can be considered a scientific object and in what respects it cannot. In the second part of this paper, More’s “Spirit of Nature” is compared to Newton’s various attempts at presenting a metaphysical cause of the force of gravity, using the similarities between the two to see this notorious (...) problem of Newton scholarship in a new light. One thus sees that if Newton drew from Stoic and Neo-Platonic theories of aether or soul of the world, we need to fully acknowledge the fact that these substances were traditionally of a non-dualistic, half-corporeal, half-spiritual nature. Both More’s “Spirit of Nature” and Newton’s aether can thus be understood as different attempts at incorporating such a pneumatic theory into the framework of modern physics, as it was then being formed.

At eighty-five, Jacques Maritain, the most distinguished Catholic philosopher of the twentieth century, has written what he offers as his last book, and it turns out to be a shocker. The peasant, as Maritain calls himself in the title, is a man who calls a spade a spade; and a storm of controversy descended immediately on the book's publication in France, as both Right and Left reeled from the force of Maritain's criticism.The Peasant of the Garonne is a sharp (...) attack on the new philosophy, hoping to cool off the fever for change that Maritain believes is imperiling the church's traditional spirituality and even the substance of doctrine. There is sardonic humor in his treatment of Teilhardians, phenomenologists, existentialists, new-style biblical critics, and clerical Freudians, but Maritain is deeply serious in warning that their capitulation to fashioniable trends represents a kind of kneeling before the world.

This is the first ever English rendition of the classic statement of divine right absolutism, published in 1707. Jacques-Benigne Bossuet argues in the Politics that a general society of the entire human race, governed by Christian charity, has given way (after the Fall) to the necessity of politcs, law, and absolute hereditary monarchy. That monarchy - seen as natural, universal and divinely ordained (beginning with David and Solomon) is defended in the first half of the book. The last part, (...) added soon before Bossuet's death, goes on to take up the rights of the Church, the distinction between absolutism and arbitrariness, and causes of just war. Patrick Riley has provided full supporting materials including a chronology, guide to further reading, and a lucid introduction placing Bossuet in his historical and intellectual context. (shrink)

In 1996 Jacques Derrida gave a lecture at the Museum of Modern Art in New York on the occasion of Antonin Artaud: Works on Paper, one of the first major international exhibitions to present the avant-garde dramatist and poet's paintings and drawings. Derrida's original title, "Artaud the Moma," is a characteristic play on words. It alludes to Artaud's calling himself Mômo, Marseilles slang for "fool," upon his return to Paris in 1946 after nine years in various asylums, while playing (...) off of the museum's nickname, MoMA. But the title was not deemed "presentable or decent," in Derrida's words, by the very institution that chose to exhibit Artaud's work. Instead, the lecture was advertised as "Jacques Derrida... will present a lecture about Artaud's drawings." For Derrida, what was at stake was what it meant for the museum to exhibit Artaud's drawings and for him to lecture on Artaud in that institutional context. Thinking over the performative force of Artaud's work and the relation between writing and drawing, Derrida addresses the multiplicity of Artaud's identities to confront the modernist museum's valorizing of originality. He channels Artaud's specter, speech, and struggle against representation to attempt to hold the museum accountable for trying to confine Artaud within its categories. Artaud the Moma, as lecture and text, reveals the challenge that Artaud posed to Derrida—and to art and its institutional history. A powerful interjection into the museum halls, this work is a crucial moment in Derrida's thought and an insightful, unsparing reading of a challenging writer and artist. (shrink)

La philosophie s'en réfère à un archétype qu'elle invoque pour calibrer les choses : la Raison ou le Logos. Mais Marx, Nietzsche, Freud et d'autres ont commencé à relativiser ce qu'une Raison apparemment immuable semblait peser à l'étalon de sa mesure. L'auteur montre combien peu de raison entre dans la constitution de notre monde quotidien, combien la convention et le langage lui imposent leurs hiéroglyphes, leurs rites et leurs systèmes.

L'auteur de cet essai tente de circonscrire l'aventure philosophique de la "quête de la vérité", en s'inspirant des recherches les plus récentes de l'épistémologie et de la logique, essayant de trouver dans la praxis des pierres d'achoppement pour un discours au moins tendanciellement vrai. Dans la confusion politique et culturelle de ce siècle, des vérités multiples prétendent avoir droit à l'expression. On parle d'intelligence digitalisée et artificielle, de désinformation, d'infox, d'intox, de propagande, de mensonges, de vérités alternatives. Ça caquète et (...) ça rugit de toutes parts, voulant soutenir la véracité par la force ou la répétition. Surtout dans ce qui se vante comme l'extrême conquête de notre civilisation occidentale, la démocratie, les harangues et les verbiages sont souvent vides de contenus, des baudruches regorgeant de promesses vaines et de captations factices. De gros intérêts financiers ou des déformations idéologiques se cachent derrière un discours qui se prétend précis et neutre. Il n'est pas étonnant de voir maint citoyen perdu dans cette cacophonie ambiante, de le voir découragé devant son manque d'information fiable et d'action cohérente. Pourtant les choses qu'il vit et qu'il sent sont dures et réelles. Elles ont des angles qui parfois font mal. La vérité existe... quelque part et de quelque façon."--Page 4 of cover. (shrink)

In my paper, I dispute Christian Hengstermann’s analysis of More’s philosophical system as a form of panentheistic panpsychism in which matter is alive by virtue of being the last emanation from God. I show that, in his mature period, More explicitly rejected such an emanationist doctrine and attributed the non-mechanical powers of matter to an outside immaterial principle, the Spirit of Nature. Ultimately, this leads to a system in which divine space, the Spirit of Nature and the spirit of God (...) are representations of various aspects of the divine essence, as it is at work in the world. On the other hand, matter is not part of this triadic structure and can only be said to be alive at the cost of a rather counterintuitive redefinition of the notion of “life”. (shrink)

Qu'est-ce qui délimite le sens et le non-sens, ce qui peut être dit et ce qui ne peut pas être dit? Comme réponse, Jacques Bouveresse propose une réflexion sur la signification linguistique, à partir des principales théories sur la limite des sens, des philosophes contemporains comme Frege, Husserl, et Wittgenstein.

Que peut le bon sens comparé à ce que peut peut-être la connaissance scientifique ? Noam Chomsky a rappelé que le progrès des sciences a amené à se rendre compte que le bon sens, ou sens commun, pouvait se tromper de façon spectaculaire. La même chose n’est-elle pas susceptible de se passer en matière morale et politique ? Après tout, le sens commun un peu éduqué ne peut-il suffire pour nous procurer les lumières dont nous avons besoin pour l’action ? (...) Pierre Bourdieu était évidemment convaincu que la connaissance procurée par les sciences sociales est finalement la seule qui soit susceptible de nous permettre de comprendre réellement les mécanismes qui engendrent l’inégalité, l’injustice, l’oppression, etc. [Jacques Bouveresse se souvient] d’avoir pris la défense de Noam Chomsky, au moins une fois, devant Bourdieu, parce que Chomsky avait écrit que comprendre comment opèrent ces mécanismes d’assujettissement et d’oppression qui engendrent l’inégalité et l’injustice n’est pas très difficile ; il suffit d’un peu de bon sens, de psychologie – et de cynisme, ajoutait-il.
