"De Charles S. Peirce, logicien et philosophe américain (1839-1914), on sait généralement qu'il a élaboré une théorie du signe, voire qu'il est le fondateur du pragmatisme. Ce que l'on sait moins, c'est qu'il est le premier à avoir développé une conception de l'information dans le cadre de ses recherches sur la philosophie de la science. Ce livre est l'étude des fondements logiques et sémiotiques de cette conception. Il se concentre sur les années 1865-1867, durant lesquelles Peirce définit les parties principales (...) de son système philosophique et montre que la notion d'information est un élément essentiel de ce système. La question que pose Peirce est de savoir comment et dans quelle mesure les représentations sont capables d'augmenter la quantité de ce qu'elles représentent. Il découvre qu'elles peuvent le faire de deux manières, selon qu'elles participent de l'un ou l'autre des deux types d'inférences probables que sont l'induction et l'abduction. L'information est la mesure de cette croissance de la connaissance au coeur des représentations. La notion d'information s'inscrit dans le type de réalisme qui définit la première période de la philosophie de Peirce. Elle est aussi un élément précurseur de ce qu'il appellera plus tard sa "logique du vague"."--Page 4 of cover. (shrink)

Est-il vrai que la notion chrétienne de création soit une notion complètement nouvelle par rapport à la philosophie grecque ? Telle est la question qu'on se pose dans l'article ci-dessus. Si d'habitude on est incliné à répondre à cette question par l'affirmative, c'est en admettant que, assez généralement, la philosophie grecque connaît l'idée d'une matière préexistante. C'est ainsi que les apologètes grecs du deuxième siècle, tels qu'Aristide et Théophile d'Antioche, se sont opposés à la philosophie grecque et spécialement à la (...) doctrine de Platon telle qu'ils l'ont comprise. L'auteur essaie de démontrer que, en fait, Platon n'a pas admis une matière préexistante dans le sens voulu par ses adversaires. Il n'a ni enseigné que les éléments préexistassent à l'œuvre créatrice du Démiurge , ni introduit sa notion d' espace dans le sens de matière, telle qu'Aristote, suivant sa propre terminologie, a voulu l'expliquer. C'est donc une erreur de dire que Platon ait admis une matière qui soit « coéternelle » et « du même âge », donc du même ordre que Dieu. Pour Platon, et pour Aristote également, le principe non déterminé ne saurait, comme tel, être du même orde que le premier Principe de l'être qui est comme tel un principe déterminant et déterminé. C'e'st une erreur, encore, de dire que, sur ce point comme sur beaucoup d'autres, Aristote était plus près de la vérité, donc du Christianisme, que Platon, le « Démiurge » du dernier n'étant pas une cause totale, tandis que le Premier Moteur d'Aristote était, dans un sens, vraiment une cause totale. Ce qui se voit clairement chez Platon, non seulement dans le Timée, mais aussi dans la République et dans le Philète , c'est qu'il est constamment et profondément préoccupé de fonder l'existence relative dans l'Existence absolue. Il a reconnu le rapport entre le monde visible et le Monde transcendant comme une relation de dépendance totale et essentielle. Or, si, dans son essence, la notion chrétienne de création n'est autre chose qu'une telle relation de dépendance, Platon, qui a fait de cette notion la base de toute sa philosophie, était par là-même près de la foi chrétienne. Aristote, d'autre part, bien qu'il ait dit une fois au moins que de son premier Principe tout l'univers dépend, a minimisé en fait le rapport entre le premier Principe et notre monde. Dans la notion chrétienne de création deux éléments se dissinguent : L'Etre Absolu, dont sort tout ce qui est relatif, se distingue dans son essence de tout ce qui n'est pas Lui. Le mode selon lequel l'être relatif sort de l'Absolu n'est pas celui d'une nécessité de nature, mais d'un acte de volonté. En partant de cette analyse, on peut déterminer exactement les degrés de différence ou d'affinité entre la notion chrétienne de création et les différents systèmes de philosophie grecque. En rapport avec la Stoa, la différence est dans la notion de Dieu : ne reconnaissant pas sa transcendance, on méconnaît l'opposition entre l'Absolu et l'être relatif. Quant à Aristote, il n'explique aucunement comment l'être relatif provient de l'Absolu : son premier Moteur n'est pas la cause de l'être, et les « formes » immanentes des objets naturels restent chez lui sans aucune explication. Sans doute, Platon explique davantage. Il est suivi par les Néoplatoniciens qui font provenir l'être relatif de l'Absolu, tout en connaissant une différence essentielle entre l'un et l'autre, mais n'admettant point d'acte de volonté de la part de l'Absolu. Platon qui, probablement, admettait un acte de volonté, se trouvait par là-même le plus près de la notion chrétienne de création. Il en différait, cependant, sur quelques points importants. Il n'enseigne qu'en partie une création directe : c'est que le Nous transcendant qui est le Démiurge, constitue des éléments le monde visible ; ces éléments, il ne les a pas trouvés comme tels, mais il les a faits de — « quelque chose » qu'on n'a pas le droit de nommre une chose. Il « fait » donc le monde dans son aspect intelligible. Mais il reste un aspect qui échappe à la pensée et qui, comme tel, ne saurait provenir du Principe Suprême qui domine la hiérarchie platonicienne de l'être. Ensuite, le Nous transcendant fait les âmes : l'âme du monde, les astres , les âmes humaines. Il ne fait ni les corps humains ni les êtres vivants d'un ordre inférieur à l'homme. Ceux-là, ils sont tous créés par les « dieux créés » et secondaires qui sont les Astres. Pour Platon, l'Esprit transcendant qui crée le monde n'est pas le Principe suprême. Il se trouve d'après ce qu'il paraît, à un degré plus bas dans la hiérarchie de l'être. Ce seront les penseurs chrétiens, ce sera tout d'abord Saint Athanase qui, en unifiant essentiellement le Père et son Logos, a réuni l'Un et le Nous transcendant qui est le Démiurge de Platon. Au lieu d'opposer au Platonisme la doctrine qu'il n'y a pas de matière préexistante, Dieu ayant « concréé » la matière, nous préférons de dire : Platon a éloigné la notion d'infini et d'indétermination de son principe suprême ; donc, il en a fait un autre principe, jamais du même ordre que l'Un, mais tout de même un principe fondamental. La notion chrétienne de Dieu, d'autre part, renferme et le caractère de l'Un et celui de l'Infini. (shrink)

This paper tries to trace the different evolutional stages the egg of primitive chordates had to pass through to reach the complex state of the bird egg . It tries to ascribe to the evolutional stages the successive appearance of transitional particularities which characterise the egg and the ontogeny of birds.The different forms of individual development in birds are classified in 7 groups, proceeding from primitive to more advanced types. The type of Galliformes, especially of the Megapodidae, is shown to (...) be very probably the most primitive one, while the Passeriformes show the highest degree of advanced specialisation.Proceeding from the primitive stages of chordates to the more advanced stages of brids a steadily growing participation of the maternal organism in the development of the young animal is stated . Corresponding to this participation we find the young in a more and more intimate dependance of the mother — a dependance that unites the young and his parents in a “system” just as complicated as that built up by the young mammal and its mother. The comparative study allows us to trace the progressive evolution of such a system in avian phylogeny.Ce travail essaie d'établir les stades de l'évolution par lesquels l'oeuf des cordés primitifs a dû successivement passer pour atteindre l'état complexe réalisé dans l'oeuf des oiseaux . Nous essayons ici d'attribuer aux stades évolutifs l'apparition successive de particularités transitoires qui, dans leur totalité, caractérisent l'oeuf et l'ontogénèse des oiseaux.Les différentes formes de l'ontogénèse des oiseaux sont groupées en 7 catégories, allant d'un mode reconnu primitif à un autre mode évolué. Les Gallinacés, en particulier les Mégapodides, nous paraissent se rapprocher le plus du stade primitif; les Passereaux semblent représenter le stade le plus avancé.En passant des stades primitifs des cordés aux stades plus évolués des oiseaux, on constate une participation progressive de la mère à l'ontogénèse de l'espèce . De cette participation résulte une dépendance de plus en plus étroite du jeune animal — dépendance qui unit les parents et leur progéniture en un „système” supérieur dépassant l'individu seul et qui n'est pas moins complexe que celui formé par la mère et l'enfant des mammifères. L'étude comparative permet actuellement de suivre l'évolution progressive d'un tel système dans la phylogénèse des oiseaux. (shrink)

Résumé Cet article présente l’analyse d’une expérience de construction de savoirs mathématiques en rapports avec les machines, dans les années 1950 et 1960, à une époque où le calcul analogique cohabitait avec le calcul digital (c’est-à-dire le futur « ordinateur », terme introduit dans la langue française pour désigner principalement les « digital computers »). Les mathématiques en jeu relèvent des théories des systèmes dynamiques, c’est-à-dire des outils mathématiques construits pour comprendre la dynamique de différents types de systèmes, qu’ils soient (...) mathématiques, physiques, biologiques, mécaniques, etc. L’objet du présent article est à la fois un groupe de chercheurs, leurs pratiques de « mathématiques pour l’ingénieur », leurs efforts pour construire des calculateurs analogiques (mécanique ou électronique) pour étudier la dynamique, le programme baptisé « Dynamique théorique » qu’ils se sont fixés, et l’épistémologie des mathématiques sous-tendant leur pratique.

This paper presents a novel approach to the unsupervised learning of syntactic analyses of natural language text. Most previous work has focused on maximizing likelihood according to generative PCFG models. In contrast, we employ a simpler probabilistic model over trees based directly on constituent identity and linear context, and use an EM-like iterative procedure to induce structure. This method produces much higher quality analyses, giving the best published results on the ATIS dataset.

The concept of performance has gradually become established in health policies. Presented as necessary and positive, it is often reduced to efficiency, which results in policies and management styles aimed at optimisation. While they are supposed to guarantee the sustainability of our healthcare systems, these practices have made them fragile. Insights from the life sciences help us understand why. Indeed, biologists observe that living beings do not prioritise optimisation but robustness. To cope with fluctuations, a robust organisation operates with redundancies, (...) apparent waste, heterogeneity, organised fluctuations, slowness, and hesitation. It functions sub‐optimally. This article offers a theoretical reflection and management directions for more robust healthcare systems. (shrink)

From an evolutionary point of view, the function of moral behaviour may be to secure a good reputation as a co-operator. The best way to do so may be to obey genuine moral motivations. Still, one's moral reputation maybe something too important to be entrusted just to one's moral sense. A robust concern for one's reputation is likely to have evolved too. Here we explore some of the complex relationships between morality and reputation both from an evolutionary and a cognitive (...) point of view. (shrink)

Interest in the political relevance of the emotions is growing rapidly. In light of this, Hannah Arendt’s claim that the emotions are apolitical has come under renewed fire. But many critics have misunderstood her views on the relationship between individuals, emotions and the political. This paper addresses this issue by reconstructing the conceptual framework through which Arendt understands the emotions. Arendt often describes the heart – where the emotions reside – as a place of darkness. I begin by tracing this (...) metaphor through her work to demonstrate that it is meant to convey the inherently uncertain nature of emotions rather than a devaluation of them. I proceed to challenge the notion that Arendt adopts the Enlightenment dichotomy between reason and emotion. In fact, she rejects both as a basis for politics. However, she does identify some constructive roles for the emotions. I argue that fear is intrinsically connected to courage – the principal political virtue – in Arendt’s philosophy. In ligh...

Many legal theorists have argued that analogical reasoning is merely rule-following in which the general rule is not stated. Lloyd Weinreb's tries to defend the practice of analogical reasoning on its own terms. He does so by giving examples of the way people use analogical reasoning, both in legal and non-legal contexts, as a means for deciding how to act in particular circumstances. By itself such evidence does not support Weinreb's case, because to justify analogy he must show that analogical (...) reasoning can somehow lead us to correct answers. Moreover, his evidence does nothing to challenge the claim that analogical reasoning is simply following suppressed rules.I try to give Weinreb a helping hand. I use the data he mentions that people actually reason by analogy as a starting point for a novel justificatory account of analogical reasoning based on the notion of reliable results: a process of reasoning is reliable, and therefore reliance on it justified, if it tends to generate correct results. This requires explaining what counts as correct results in law, which is a question of political philosophy. I show that the most fundamental condition for the acceptability of analogical reasoning is that the standard of legal correctness is not determined by principles derived by Reason (as is the approach in the civil law tradition) but rather by a standard of acceptance (more prevalent in the common law tradition). Nonetheless, I argue that there two other conditions - shared social values and skepticism about the possibility of discovering the right normative foundations to legal questions - that together have to obtain in order to justify reliance on analogical reasoning. Since that in a modern society it is unlikely that these two conditions are not likely to obtain, I conclude that even this sympathetic reconstruction of Weinreb's argument ultimately fails.

Contemporary legal philosophy is predominantly anti-naturalistic. This is true of natural law theory, but also, more surprisingly, of legal positivism. Several prominent legal philosophers have in fact argued that the kind of questions that legal philosophers are interested in cannot be naturalized, such that a naturalistic legal philosophy is something of a contradiction in terms. Against the dominant view I argue that there are arguable naturalistic versions of both legal positivism and natural law. Much of the essay is dedicated to (...) showing that such views are possible: I identify naturalistic versions of a “natural law” view, a “positivist” view, as well as a “semi positivist” view, all of which are variants of the familiar views defended under these labels. I also offer a tentative argument in support of a naturalistic positivist view, one that has more in common with the views of Thomas Hobbes and Jeremy Bentham than with the anti-naturalistic positivist views popular these days.

Despite the relevance of silence in several psychopathologies, first-person perspectives on silence have been largely neglected in the phenomenological scholarship on those conditions. This paper proposes a phenomenological framework for addressing this neglect and demonstrates its usefulness through a case study of empty silence, an experience which can be found in many first-person accounts of depression. The paper begins by surveying research on silence in depression in mental health research and phenomenological psychopathology. Drawing on the thought of Merleau-Ponty, it then (...) outlines a phenomenological framework for explicating the structure of silence experiences in psychopathology. Finally, it applies this framework to articulate the experiential structure and implications of empty silence, with a particular emphasis on the bodily doubt that can flow from repeated experiences of empty silence.

I’m grateful for the opportunity to give the 2019 AJTP Lecture and for the leeway since then allowed me in developing ideas first presented there; it is indulgent of this journal to publish the overlong result in two parts, of which this is the first.1 The philosophical tradition epitomized by William James and Charles S. Peirce figured importantly in my early philosophical formation, but I am not a scholar of their work; nevertheless, Mike Hogue—at the time the editor of AJTP (...) and once a doctoral student at the University of Chicago Divinity School at the same time as me—approached me about the AJTP Lecture after learning that I had taught a class in the University of Chicago Divinity School called “American...

This paper will introduce the notion of a naming convention and use this paradigm to both develop a new version of the Second Incompleteness Theorem and to describe when an axiom system can partially evade the Second Incompleteness Theorem.

For Pieper, the study of tradition is anything but antiquarian. He begins with a consideration of tradition in a changing world and is well aware of the need to confront the all-too-common perception that "tradition" is nowadays irrelevant. On the basis of his profound knowledge of the Western philosophical tradition from Plato and Aristotle through Augustine, Boethius, Thomas Aquinas, and Descartes, to modern Existentialism and Marxism, Pieper is able to highlight the values established - and challenged - down through the (...) centuries. He sees the need to re-examine these values, to rid them of the false interpretations and misunderstandings that threaten to consign them to oblivion. He attempts to restate them in language which, in fact, not only reflects the clarity of his mind but also expresses his conviction that these values, freshly examined and understood, provide a sound basis for healthy living and for our survival against the dangers that pose a serious threat to the very existence of Western civilization. He illustrates these values by examining the contrast between an exponent of them, like Socrates, and an opportunist, like the Sophist Protagoras; between the man of principle and the nihilistic pragmatist. The book consists of a mixture of articles and speeches, produced by a man who, though often wooed by the academy, was not concerned with achieving personal status as an academic professor. He insisted, for the most part, in combining purely academic teaching with the education of teachers in teacher-training colleges. He would not be removed from close contact with "learners," and he remained a "learner" himself - from tradition. (shrink)

If K is an index of relative voting power for simple voting games, the bicameral postulate requires that the distribution of K -power within a voting assembly, as measured by the ratios of the powers of the voters, be independent of whether the assembly is viewed as a separate legislature or as one chamber of a bicameral system, provided that there are no voters common to both chambers. We argue that a reasonable index – if it is to be used (...) as a tool for analysing abstract, ‘uninhabited’ decision rules – should satisfy this postulate. We show that, among known indices, only the Banzhaf measure does so. Moreover, the Shapley–Shubik, Deegan–Packel and Johnston indices sometimes witness a reversal under these circumstances, with voter x ‘less powerful’ than y when measured in the simple voting game G1 , but ‘more powerful’ than y when G1 is ‘bicamerally joined’ with a second chamber G2 . Thus these three indices violate a weaker, and correspondingly more compelling, form of the bicameral postulate. It is also shown that these indices are not always co-monotonic with the Banzhaf index and that as a result they infringe another intuitively plausible condition – the price monotonicity condition. We discuss implications of these findings, in light of recent work showing that only the Shapley–Shubik index, among known measures, satisfies another compelling principle known as the bloc postulate. We also propose a distinction between two separate aspects of voting power: power as share in a fixed purse (P-power) and power as influence (I-power). (shrink)

I take a close look at Bernard Williams’s paper "Moral Luck," which put this notion on the philosophical agenda. Williams’s focal example is the painter Paul Gauguin. According to Williams, Gauguin’s morally dubious decision to desert his family so as to pursue an artistic career can be redeemed only by his partially fortuitous success as a painter. This is shown by the consideration that a successful Gauguin would not be able to regret his decision, whereas failure would have prompted regret. (...) I suggest that the best way to understand this claim is to see Gauguin’s decision to become an artist as a constitutive decision, which launches what for him proved to be a defining project. One cannot coherently regret the realization of such a project or the decision that gave rise to it because that would amount to wishing to be someone else: conditions of personal identity set the limits on the counterfactuals about ourselves that we can intelligibly entertain. However, not being able to regret the constitutive elements of one’s life is not the same as approving of these elements. So I disagree with Williams’s ultimate conclusion that the inability to regret a decision signals some justification for it, no matter how attenuated. (shrink)

We consider that the research conducted on the totalitarian phenomenon has still remained a challenge for political philosophy and social sciences, even though most of the totalitarian regimes are now a matter of the past. However, its consequences and the threat of its reinvigoration have remained as well. Under the circumstances, the theoretical instruments that make possible an effective euristic approach of the phenomenon are particularly important. Among these instruments, the totalitarian personality concept occupies a foreground place. What we advance (...) is a new perspective upon this concept. We believe that thetotalitarian personality can be and must be regarded as a by-product of totalitarianism, not solely as one of its prerequisites. We can and we must give emphasis to the totalitarian imprint upon personality, upon the more or less profound transformations undergone by the personality of those who lived through the totalitarian experience.

The concept ‘personhood’ lies at the center of contemporary disputes concerning whether certain biological interventions are ethical. Thus, if ‘personhood’ could be located or its existence evidenced by observations available to biologists, then each of these controversies could be resolved in biology’s own terms. I argue that this is a fruitless task. The attempt to track down a material object, ‘personhood,’ reveals ignorance of an important metaphysical presupposition underlying contemporary culture’s Cartesian/Kantian concept of ‘personhood’.

In this article I shall analyse and evaluate analytic theists’ views of what it takes to be a person of faith. I suggest that the subject can be approached by posing requirements a person must allegedly fulfil in order to count as a person of faith. These requirements can be referred to as aspects of faith. According to my analysis, four different aspects of faith can be distinguished: the cognitive, the evaluative-affective, the practical, and the interpersonal. There have been divergent (...) assessments about which aspects are indispensable for faith and how they should be understood. (shrink)

Competent adults should be permitted to determine the course of their own lives. We may try to influence them. We may ask them, perhaps even implore them, to change their minds. But in the end, they are in charge of their lives. They get to choose their careers, whether and whom to marry, whether to exercise, and whether to have surgery.This emphasis on respect for patients’ autonomy may seem to imply that allowing patients to make their own decisions should always (...) take precedence over other considerations. Given this presumption, there has been almost no discussion in the medical literature or elsewhere about how important this value is and whether it should sometimes be balanced against and give way to other values. This absence of guidance is especially problematic in cases where respect for patient autonomy conflicts with promoting patients’ clinical interests. (shrink)

In voting theory, monotonicity is the axiom that an improvement in the ranking of a candidate by voters cannot cause a candidate who would otherwise win to lose. The participation axiom states that the sincere report of a voter’s preferences cannot cause an outcome that the voter regards as less attractive than the one that would result from the voter’s non-participation. This article identifies three binary distinctions in the types of circumstances in which failures of monotonicity or participation can occur. (...) Two of the three distinctions apply to monotonicity, while one of those and the third apply to participation. The distinction that is unique to monotonicity is whether the voters whose changed rankings demonstrate non-monotonicity are better off or worse off. The distinction that is unique to participation is whether the marginally participating voter causes his first choice to lose or his last choice to win. The overlapping distinction is whether the profile of voters’ rankings has a Condorcet winner or a cycle at the top. This article traces the occurrence of all of the resulting combination of characteristics in the voting methods that can exhibit failures of monotonicity. (shrink)
