"[Heidegger's] greatest work... essential for all collections." —Choice "... students of Heidegger will surely find this book indispensable." —Library Journal Contributions to Philosophy, written in 1936-38 and first published in 1989 as Beiträge zur Philosophie, is Heidegger’s most ground-breaking work after the publication of Being and Time in 1927. If Being and Time is perceived as undermining modern metaphysics, Contributions undertakes to reshape the very project of thinking.

Many existence propositions in constructive analysis are implied by the lesser limited principle of omniscience LLPO; sometimes one can even show equivalence. It was discovered recently that some existence propositions are equivalent to Bouwer's fan theorem FAN if one additionally assumes that there exists at most one object with the desired property. We are providing a list of conditions being equivalent to FAN, such as a unique version of weak König's lemma. This illuminates the relation between FAN and LLPO. Furthermore, (...) we give a short and elementary proof of the fact that FAN is equivalent to each positive valued function with compact domain having positive infimum. (shrink)

Despite his predominance in twentieth-century philosophy, no intellectual biography of Martin Heidegger has yet appeared. This account of Heidegger's personal relations, originally published in German and extensively corrected by the author for this translation, enlarges our understanding of a complex figure. A well-known art historian and an intimate friend of Heidegger's, Heinrich Wiegand Petzet provides a rich portrait of Heidegger that is part memoir, part biography, and part cultural history. By recounting chronologically a series of encounters between the two friends (...) from their meeting in 1929 until the philosopher's death in 1976, as well as between Heidegger and other contemporaries, Petzet reveals not only new aspects of Heidegger's thought and attitudes toward the historical and intellectual events of his time but also the greater cultural and social context in which he articulated his thought.

Working within Bishop’s constructive framework, we examine the connection between a weak version of the Heine–Borel property, a property antithetical to that in Specker’s theorem in recursive analysis, and the uniform continuity theorem for integer-valued functions. The paper is a contribution to the ongoing programme of constructive reverse mathematics.

Qu'Éclane soit le siège de l'évêché de Julien est un fait bien établi. Mais quelle était sa patrie d'origine? Cet article résume un certain nombre de suggestions faites au cours des derniers siècles et jette un oeil neuf sur les sources. Prenant en considération aussi bien le domaine des textes que ceux de l'histoire, de la géographie ou de l'ethnologie, l'auteur arrive à la conclusion qu'Éclane fut non seulement le siège de l'évêché de Julien mais également son lieu de naissance.

It is shown, with intuitionistic logic, that if every locally constant function from to has a property akin to constancy, then the fan theorem for -bars holds, and conversely.

It is shown that, relative to Bishop-style constructive mathematics, the boundedness principle BD-N is equivalent both to a general result about the convergence of double sequences and to a particular one about Cauchyness in a semi-metric space.

Cet article présente une vue d'ensemble de l'histoire de la recherche sur la structure et le sujet de «De vera religione», ainsi que de nouvelles suggestions.

Abstract:This article addresses the issue of whether and to what extent moral values can be attributed to collective actors. The paper starts from the premise that business ethics as the ethics of an organization is to be distinguished from the virtues of its members. This point is elaborated in both economic- and organization-theoretic terms within the framework of the New Economics of Organization. The result is the development of a concept of governance ethics. The ethics of governance is about the (...) incorporation of moral conditions and requirements in the management, governance, and control structures of a firm. This is the contextual precondition for the long-lasting and beneficial effects of the virtues of individuals within the organizations. (shrink)

Nach Kant bleibt alles Denken auf das einzelne Subjekt des Denkens und seine Möglichkeiten zurückbezogen. Simon beschreibt Kants Werk als ein System, das den eigenen Denkansatz als einen Besonderen neben anderen begreift. Auch wenn das Subjekt anderes Denken nicht immer von sich aus versteht, bezieht es jenes als "fremde Vernunft" in seine Weltorientierung ein und erkennt es an. Damit ergibt sich die Notwendigkeit des Findens einer Sprache, in der im Ausgang vom eigenen Vorverständnis anderen etwas so gesagt werden kann, dass (...) es auch ihnen "etwas" bedeutet und in diesem Sinne als wahr erscheint. Von hier aus verändert sich dann der Begriff der Bedeutung und die Sprache der Philosophie. (shrink)

Libet considers “positive free voluntary acts” as mere illusions, admitting free will only as Veto. This essay shows seven ways by which we can gain evident knowledge about positive and negative free will, through: (1) the immediate evidence of free will in the cogito, (2) the light of the necessary essence of free will, (3) the experience of moral “oughts” in whose experience freedom is co-given, (4) any denial of human free will entails its assertion or recognition, (5) the objects (...) and subjects of certain acts disclose free will, (6) in a world without free agents there would be no explanation of the beginning of efficient causality, and (7) Veto-power of the will logically presupposes positive free will. Libet’s experiments confirm that the free decision to act at a certain time and the preceding and accompanying free acts make new energy to burst forth in the brain. (shrink)

The modern (Russellian) theory of definition conceives definitions as abbreviations, so that the question of adequateness (let alone of truth-value) of definitions becomes meaningless. In this paper we show that beside Russellian conception of definitions understood as abbreviations, there is an Aristotelian conception, which exploits the notion of essence and that this conception can be rehabilitated from the standpoint of the modern logic (in particular by means of Pavel Tichý’s Transparent Intensional Logic). Also Carnap’s ‘explication’ indicates that what we feel (...) to be a definition is frequently distinct from a Russellian definition. (shrink)

Plato's famous dialogue, the Phaedrus, was variously subtitled in antiquity: "On Beauty", "On Love", "On the Psyche". It is also concerned with the art of rhetoric, of thought and communication. Pieper, noted for the grace and clarity of his style, gives an illuminating and stimulating interpretation of the dialogue. Leaving the more recondite scholarly preoccupations aside, he concentrates on the content, bringing the actual situation in the dialogue -- Athens and its intellectuals engaged in spirited debate -- alive. Equally alive (...) is the discussion of ideas, which are brought to bear on contemporary experience and made to prove the perennial validity of Socratic wisdom, and its power to excite the mind. The main thesis -- that in poetry and in love man is "beside himself", that is, divinely inspired -- is discussed with reference to modern poets, novelists, and modern psychology. (shrink)

Three and 4-year-old children were tested on matched versions of Zaitchik's (1990) photo task and Wimmer and Perner's (1983) false belief task. Although replicating Zaitchik's finding that false belief and photo task are of equal difficulty, this applied only to mean performance across subjects and no substantial correlation between the two tasks was found. This suggests that the two tasks tap different intellectual abilities. It was further discovered that children's performance can be improved by drawing their attention to the back (...) of the photo but not by drawing attention to the person holding the false belief. Results are interpreted as showing that children's difficulty with the photo task is due to referential confusion about which scene the question refers to (the picture or reality) while the hurdle in the false belief task is to understand that the believer misrepresents reality.
