We characterize the completely determined Borel subsets of HYP as exactly the [Formula: see text] subsets of HYP. As a result, HYP believes there is a Borel well-ordering of the reals, that the Borel Dual Ramsey Theorem fails, and that every Borel d-regular bipartite graph has a Borel perfect matching, among other examples. Therefore, the Borel Dual Ramsey Theorem and several theorems of descriptive combinatorics are not theories of hyperarithmetic analysis. In the case of (...) the Borel Dual Ramsey Theorem, this answers a question of Astor, Dzhafarov, Montalbán, Solomon and the third author. (shrink)

In 1902 Henri Lebesgue (1875-1941) published his thesis containing a new theory of integration which was based on Borel's theory of measure. Independently of this William Henry Young (1863-1942) together with his wife Grace Chisholm Young (1868-1944) developed a similar theory of measure and integration. Only after submitting their papers on this subject to the London Mathematical Society did they learn about Lebesgue's results. Consequently the Youngs decided to publish a revised version in which the concept of Lebesgue (...) was taken into consideration and discussed. This parallel discovery will be analysed both from a mathematical and a psychological point of view. The previously unpublished primary sources from the private correspondence of the Youngs will be used to illuminate the collaboration between the Youngs and their reaction to Lebesgue. (shrink)

Pragmatism, taken not just as a philosophical movement but as a way of addressing problems, strongly influenced the debate on the foundations of probability during the first half of the twentieth century. Upholders of different interpretations of probability such as Hans Reichenbach, Ernest Nagel, Rudolf Carnap, Frank Ramsey, and Bruno de Finetti, acknowledged their debt towards pragmatist philosophers, including Charles Sanders Peirce, William James, Clarence Irving Lewis, William Dewey and Giovanni Vailati. In addition, scientist-philosophers like Ernst Mach, Ludwig Boltzmann, (...) class='Hi'>Henri Poincaré, Pierre Duhem, and Karl Pearson, who heralded a conception of science and knowledge at large that was close to pragmatism, were very influential in that debate. Among the main interpretations of probability – frequentism, propensionism, logicism and subjectivism -, the latter is no doubt the closest to the pragmatist outlook. This paper concentrates on three representatives of the subjective theory, namely Frank Ramsey, Bruno de Finetti and Émile Borel. (shrink)

The ArgumentThe status of the person is analyzed as represented by the life sciences under the influence of modern physico–chemical and molecular biology.At the same time the linguistic structure of reality as seen through formalized scientific discourse is not that of a language, but rather that of operational symbolisms, so that the judeo–Greek tradition of Verb as creating and Logos as procreating — which is probably at the origin of the surprising confidence in the possibility of dominating nature through words (...) and formulae — could be suc–cessful only through the depersonalization of language.Notwithstanding appearances, the phenomena of structural and functional self–organization do not really change this situation.In this context the question of the status of the person and of the intentional subject has to be dealt with pragmatically, giving up the notion of a unified scientific theory that would take into consideration at the same time the experi–mental sciences and the human sciences as linking subjectivity and intentionality.

THE VALUE OF SCIENCE INTRODUCTION The search for truth should be the goal of our activities; it is the sole end worthy of them. Doubtless we should first bend our efforts to assuage human suffering, but why ? Not to suffer is a negative ...

ZusammenfassungAus der Sicht der offenen Transzendentalphilosophie kommt es weniger auf eine physikali‐stische Gesamttheorie der Welt an als auf eine Analyse der normativen Tätigkeiten, die wir in die‐ser ausüben. Es wird gezeigt, wie wir – vor allem auch in der Wissenschaft – selbst die Voraus‐setzungen schaffen, die es uns erlauben, aufgrund von Wertungen ausgewählte Ziele zu erreichen. Pragmatische Erwägungen bedingen in einer gegebenen Situation den Entschluss, einen bestimm‐ten Kontext abzugrenzen, indem wir die dazu erforderlichen Regeln annehmen. Dadurch erzeugen wir ein relatives (...) Apriori, das uns die Mittel liefert, um zwischen analytisch und synthetisch, zwischen Sprache und Theorie etc. zu unterscheiden.Die Methode führt zu einem pluralistischen Weltbild: Nach der Wahl der linguistischen und ontologischen Bestandteile kann die Wahrheitsfrage im Sinne Tarskis nur mehr intern geregelt werden, während sich rivalisierende Systeme als ganze allein aufgrund von pragmatischen Krite‐rien vergleichen lassen.Es werden die deskriptiven und normativen Aspekte der Begriffe des Wertes, der Norm und der Regel erörtert, um schliesslich auf die zentrale Rotle zu verweisen, die Konventionen als nicht der Willkür ausgesetzte, sondern rational begrundete Festlegungen in sämtlichen unseren Aktivitäten spielen.SummaryFollowing my conception of open transcendentalism philosophy is less concerned with a naturalistically conceived theory of the world than with the normative activities we display in this world. By our own cultural and intellectual presuppositions we create the means – scientific or others – required for the achievement of certain goals which have previously been accepted as valuable. Pragmatic considerations induce us to establish, in given situations, what 1 call contexts by adopting particular rules. We thus produce a pragmatically relativized apriori providing us with a clearcut distinction between the analytic and the synthetic, between language and theory etc.The method issues in a pluralistic world view: Once the matter concerning the choice of a linguistic system and an ontology is settled the question of truth in Tarski's sense can only be raised internally while theories as a whole are compared on purely pragmatic grounds.I discuss some descriptive and normative aspects regarding the notions of value, norm and rule in order to ascertain the primary role played by conventions in all our activities. I rid the word of the connotation of arbitrairiness often attached to it in Anglo‐Saxon philosophy by restricting its use to deliberate acts concerned with rationally justified decisions.ResumeSelon ma conception du transcendentalisme ouvert, la philosophic est moins concernée par la recherche?on;une théorie globale du monde, telle que la préconise le naturalisme, que par ľanalyse des activités normatives que nous exerçons dans celuici. Nous créons nous‐mêmes les présuppositions qui nous permettent?on;atteindre un but – scientifique ou autre – dont la valeur a été préalablement admise. Ce sont des délibérations de type pragmatique qui nous incitent, dans une situation donnée, àétablir – en acceptant des règies idoines – ce que j ‘appellerai un contexte. Nous produisons ainsi un a priori relatif dont les préceptes, admettant une distinction stride entre ľanalytique et le synthétique, la langue et la théorie etc., resteront en vigueur tant que le cadre conceptuel en question prévaudra.La méthode mène à une vision pluraliste du monde: Le choix des éléments linguistiques et ontologiques une fois accompli, la question de la vérité, conformément à la définition de Tarski, ne peut être posée que de manière interne, tandis que la comparaison de systèmes rivaux s'opérera àľaide de critères purement pragmatiques.Dans la dernière partie, j'évoque quelques aspects descriptifs et normatifs des concepts de valeur, de norme et de règie afin de dégager le rôle central des conventions dans nos activités culturelles. Je libère la notion de convention de toute connotation ayant trait àľarbitraire en lui conférant le sens?on;un decision rationnellement justifyée. (shrink)

This article addresses the problem of legislation and adjudication in early states, offering examples from Africa and other parts of the world. It discusses the problems of legitimacy and governance, especially in the context of multi-ethnic populations. For some of its generalizations it draws upon a previous study of twenty-one early states.

The objective of this study is to analyze the measurability and interfirm comparability of sustainability performance through the qualitative content analysis of 12 sustainability reports of mining firms using the Global Reporting Initiative guidelines. The systematic comparison of information disclosed in 92 GRI indicators sheds light on the reasons underlying the impossibility of rigorously measuring and comparing the sustainability performance of firms from the same sector, which are supposed to be strictly following the same reporting guideline. These reasons include qualitative (...) aspects of sustainability, lack of compliance with GRI protocols, indicator contingency, ambiguous or incomplete information, data heterogeneity, and report opacity. The study makes it possible to return to the very notion of sustainability, its meaning, and flexible application by organizations. The results are discussed from three different theoretical perspectives, each of which proposes possible and complementary explanations of the main findings. (shrink)

HENRI BERGSON (1859-1941), philosophe français, professeur au Collège de France de 1900 jusqu´à 1921, récompensé avec le prix Nobel de littérature en 1928. Ses oeuvres majeures, écrites avec un style parfaitement accessible au lecteur non spécialisé, sont : « Essai sur les données immédiates de la conscience » (1889), « Matière et mémoire » (1896), « L´évolution créatrice » (1907) et « Les deux sources de la morale et de la religion » (1932). Dans ces études, Bergson élabore une (...) vision philosophique en opposition au matérialisme et positivisme scientifique. Concentrant sa recherche sur les intuitions individuelles, il prône la notion d´élan vital, lequel dirige le procès évolutif vers des états d´organisation de plus en plus complexes, et de là vient l´intérêt de donner prééminence à tout ce qui est spirituel et ouvertement créatif, sur tout ce qui est formel, fixé, fermé. Dans « Le rire : essai sur la signification du comique » (1900), il trouve que le comique est soulevé des que nous percevons dans les actions humaines les automatismes, répétitions ou dysfonctionnements qui contrastent avec l´essentielle spontanéité de la vie réelle.

This review of Turner’s “Computational Artifacts” focuses on one of the key novelties of the book, namely the proposal to understand the nature of computer programs as a “trinity” of specification, symbolic program, and physical process, replacing the traditional dualist views of programs as functional/structural or as symbolic/physical. This trinitarian view is found to be robust and helpful to solve typical issues of dualist views. Drawing comparisons with Simon’s view of the artifact as an interface, the author suggests that this (...) trinitarian view may characterize not only computational artifacts but also artifacts in general. One ambiguity is however noticed on the denotation of what Turner actually calls the “physical process.”. (shrink)

In December 1945 Thomas Mann wrote a famous letter to Adorno in which he formulated the principle of montage adopted in his novel Doctor Faustus. The writer expressly invited the philosopher to 'consider, with me, how such a work - and I mean Leverkuhn's work - could more or less be practically realized'. Their close collaboration on questions concerning the character of the fictional composer's putatively late works effectively laid the basis for a further exchange of letters. The ensuing correspondence (...) between the two men documents a rare encounter of creative tension between literary tradition and aesthetic modernism which would be sustained right up until the novelist's death in 1955. In the letters, Thomas Mann openly acknowledged his 'fascinated reading' of Adorno's Minima Moralia and commented in detail on the 'Essay on Wagner', which he was as eager to read as 'the one in the Book of Revelation consumes a book which tastes "as sweet as honey"'. Adorno in turn offered detailed observations upon and frequently enthusiastic commendations of Mann's later writings, such as The Holy Sinner, The Betrayed One and The Confessions of Felix Krull. Their correspondence also touches upon issues of great personal significance, notably the sensitive discussion of the problems of returning from exile to postwar Germany. The letters are extensively annotated and offer the reader detailed notes concerning the writings, events and personalities referred or alluded to in the correspondence. (shrink)

The human blood coagulation system comprises a series of linked glycoproteins that upon activation induce the generation of downstream enzymes ultimately forming fibrin. This process is primarily important to arrest bleeding (hemostasis). Hemostasis is a typical example of a molecular machine, where the assembly of substrates, enzymes, protein cofactors and calcium ions on a phospholipid surface markedly accelerates the rate of coagulation. Excess, pathological, coagulation activity occurs in “thrombosis”, the formation of an intravascular clot, which in the most dramatic form (...) precipitates in the microvasculature as disseminated intravascular coagulation. Thrombosis occurs according to a biochemical machine model in the case of atherothrombosis on a ruptured atherosclerotic plaque, but may develop at a slower rate in venous thrombosis, illustrating that the coagulation machinery can act at different velocities. The separate coagulation enzymes are also important in other biological processes, including inflammation for which the rapid conversion of one coagulation factor by the other is not a prerequisite. The latter role of coagulation enzymes may be related to the old and probably maintained function of the coagulation machine in innate immunity.

Bergson's central contention is that time is not measurable by any objective standard; in Duration and Simultaneity, that position is tried out against the major movement in physics of the day - Relativity. Bergson argues that Relativity fails to live up to the promise of a truly relative physics, and counter to its own spirit retains some of the objectivist assumptions of previous world views. Duration and Simultaneity was conceived in the desire to make good the new paradigm to which (...) Relativity was bound to lay claim; in the desire to be more Einsteinian than Einstein. (shrink)
