This chapter suggests that descriptive epidemiological studies like the Global Burden of Disease Study can usefully be divided into four tasks: describing individuals’ health states over time, assessing their health states under a range of counterfactual scenarios, summarizing the information collected, and then packaging it for presentation. The authors show that each of these tasks raises important and challenging ethical questions. They comment on some of the philosophical issues involved in measuring health states, attributing causes to health outcomes, choosing the (...) counterfactual against which to assess causes, aggregating and summarizing complex information across multiple domains, discounting, age-weighting, handling fetal deaths, measuring health inequalities, representing uncertainty, and assessing personal responsibility for health outcomes.

_The Foundations of Arithmetic_ is undoubtedly the best introduction to Frege's thought; it is here that Frege expounds the central notions of his philosophy, subjecting the views of his predecessors and contemporaries to devastating analysis. The book represents the first philosophically sound discussion of the concept of number in Western civilization. It profoundly influenced developments in the philosophy of mathematics and in general ontology.

The idea of a 'logic of quantum mechanics' or quantum logic was originally suggested by Birkhoff and von Neumann in their pioneering paper [1936]. Since that time there has been much argument about whether, or in what sense, quantum 'logic' can be actually considered a true logic (see, e.g. Bell and Hallett [1982], Dummett [1976], Gardner [1971]) and, if so, how it is to be distinguished from classical logic. In this paper I put forward a simple and natural semantical framework (...) for quantum logic which reveals its difference from classical logic in a strikingly intuitive way, viz. through the fact that quantum logic admits (suitably formulated versions of) the characteristic quantum-mechanical notions of superposition and incompatibility of attributes. That is, precisely the features that distinguish quantum from classical physics also serve, within this framework, to distinguish quantum from classical logic. Some light is shed on the question of whether quantum logic is a genuine logical system by introducing a natural entailment relation for quantum-logical formulas with the implication symbol. The novelty is that, although implication behaves as it should (i.e. the 'deduction theorem' holds), the order of introduction of premises is significant. The fact that a reasonable entailment relation can be formulated for quantum logic supports the view that it is a genuine logical system and not merely an algebraic formalism. (shrink)

In this paper (a sequel to [4]) I put forward a "local" interpretation of mathematical concepts based on notions derived from category theory. The fundamental idea is to abandon the unique absolute universe of sets central to the orthodox set-theoretic account of the foundations of mathematics, replacing it by a plurality of local mathematical frameworks - elementary toposes - defined in category-theoretic terms.

Seit dem 2. nachchristlichen Jahrhundert werden die Schriften von Aristoteles kommentiert. Diese Ausgabe enthält griechische Kommentare zu seinem Werk vom 3. bis 8. Jahrhundert n. Chr., u. a. von Alexander von Aphrodiensias, Themistios, Joh. Philoponus, Simplicius in griechischer Sprache.

In Ontology, quality determines beings. The quality-quantity bipolarity reveals that a conceptual logical comprehension that can include negation must be a dialectical logic. Quality is a precise characteristic of something capable of augmentation or diminution while remaining identical through differences or quantitative changes. Thus, quality and in opposition quantity are inextricably linked, giving definition to each other, so constituting a logical bipolarity. The theory is that a magnitude G is never separated from secondary qualities α and β, and therefore, a (...) measure depends on a concrete quality Gα or Gβ, that is to say on one pole of a logical bi-pole. However, the particular number, the unit, that expresses the result of a measure is the quality G alone. Examples drawn from physical and chemical experiments illustrate these ideas and elaborate the structure of the concept of opposition between the secondary qualities α and β of a magnitude G.

Les principaux problèmes que Bultmann a posés au plan de l’exégèse historique des textes évangéliques étaient commandés par des positions théologiques et continuent pour ce motif à interroger les théologiens catholiques, qui parfois le rejettent dans le camp tantôt du scientisme tantôt du dogmatisme.Contre la théologie libérale des « vies de Jésus », il élève une double protestation, d’ordre christologique : il revendique le caractère historique de la foi chrétienne, et historique : il prend au sérieux la visée eschatologique de (...) la prédication de Jésus. Marquée en ses origines par un rationalisme dogmatique, l’exégèse historico-critique travaille à son tour la théologie, l’oblige à assumer sa propre historicité et à sortir ainsi de son propre positivisme dogmatique.Réservant – à juste titre – à la foi de dire le sens de la Croix, Bultmann semble séparer le fait et le sens et mettre l’historiographie et la théologie en rapport contradictoire de double vérité. Nous savons mieux aujourd’hui qu’il n’y a de faits qu’interprétés ; la foi atteint la vérité historique des faits, mais doit renoncer à demander de les établir « scientifiquement » à une historiographie censée « objectivement neutre ». En soutenant que le sens de la Croix relève d’une décision de foi, Bultmann nous rappelle utilement, ainsi que l’a reconnu R. Marlé, qu’on ne peut jamais évacuer le skandalon de la foi.The principal problems that Bultmann presented as regards the historical exegesis of evangelical texts were guided by theological positions and continued, for this reason, to question Catholic theologians, who sometimes put him in the camp of scientism and sometimes in that of dogmatism.Against the liberal theology of the “lives of Jesus”, he raised a double protest : of a christological nature and of a historical nature . Marked in its origins by dogmatic rationalism, historical-critical exegesis works in its turn on theology, obliges it to assume its own historicity and this to escape from its own dogmatic positivism.Allowing faith – and for good reason – to decide the meaning of the Cross, Bultmann seems to separate the fact and the meaning and to put historiography and theology in contradictory rapport of a double truth. We know better today that there are only interpreted facts ; faith attains the historical truth of facts, but must renounce the demand to establish them “scientifically” to a historiography believed to the “objectively neutral”. In holding that the meaning of the Cross depends on a decision of faith, Bultmann helpfully reminds us, as R. Marlé recognized, that one can never escape the skandalon of faith. (shrink)

In this paper we study the variety of order Hilbert algebras, which is the equivalent algebraic semantics of the order implicational calculus of Bull.

Austin discusses the existence, origin, and resemblance of concepts, primarily by discussing the meaning of ‘concept’ and ‘universal’. He argues that, although sometimes it may not be harmful to talk about concepts, we neither understand the meaning of ‘concept’, nor the meaning of ‘acquiring and possessing concepts’, nor a view of concept resemblance as non-sensuous acquaintance or awareness, challenging philosophers who couch their theories in such terms to illuminating them first.

The Roman Inquisition against Heretical Depravity, also known as the Holy Office, established in 1542, and the Congregation of the Index of Prohibited Books, announced officially in 1572, undertook to protect Italy from ideas and practices that menaced the authority of the Roman Catholic Church in this world and the salvation of its members in the next. This grandiose public-health program required trained and dedicated thought police to receive and evaluate alarms from the public and, when business was bad, to (...) seek out sources of infection themselves. The resultant records of accusations, investigations, trials, condemnations, expurgations, and exceptions, if extant in its entirety, would go far to fill.. (shrink)
