The pedagogy and heuristics of Professor Dagfinn Føllesdal.

Let X be an infinite internal set in an ω1-saturated nonstandard universe. Then for any coloring of [X] k , such that the equivalence E of having the same color is countably determined and there is no infinite internal subset of [X] k with all its elements of different colors (i.e., E is condensating on X), there exists an infinite internal set Z⊆X such that all the sets in [Z] k have the same color. This Ramsey-type result is obtained as (...) a consequence of a more general one, asserting the existence of infinite internal Q-homogeneous sets for certain Q ⊆ [[X] k ] m , with arbitrary standard k≥ 1, m≥ 2. In the course of the proof certain minimal condensating countably determined sets will be described. (shrink)

Cílem studie je srovnání Platónova a Aristotelova výkladu vlastností těžké a lehké. Nejprve jsou představeny hlavní motivy obou výkladů a poté následuje srovnání z hlediska využití empirických dat, z hlediska jejich explikační síly a také co do blízkosti modernímu pojetí tíže. V závěru se ukazuje, že Aristotelova koncepce těžkého a lehkého je propracovanější a komplexnější, ovšem mnohem stručnější výklad Platónův má také značné explikační možnosti a v určitých ohledech Aristotelovu teorii předčí.

Resumo: No capítulo 5 do Livro III De anima (430a10-19) Aristóteles distingue entre o νοῦς ποιητικός (nous poietikós), chamado pelos Latinos intellectus agens (intelecto agente), e νοῦς παθητικός (nous pathetikós), chamado pelos Latinos intellectus passivus, ou seja, intellectus possibilis (intelecto possível), termos técnicos e filosóficos mais comuns. O capítulo 5 é de grande importância não só para a filosofia antiga e para os comentadores das obras de Aristóteles, como os comentários de Teofrasto, de Alexander de Afrodisias, de Simplício e Themístius (...) entre outros, mas também para a filosofia do mundo árabe e da Europa latina. Sabe-se que Aristóteles não escreveu um tratado próprio sobre o intelecto, embora possam ser encontradas várias observações acerca do intelecto em suas obras. Os tratados do Intelecto começam com Al-Kindi, Al-Farabi, Avicena e sobretudo Averróis, e se refletem, num sentido crítico e afirmativo, (nos debates) dos tratados latinos, por exemplo, nos tratados de Alberto Magno, de Tomás de Aquino, de Sigério de Brabant entre outros. Este artigo apresenta observações preliminares e preparatórias ao projeto de traduções bilíngue (Latim-Português) dos tratados medievais sobre o intelecto ‘Teorias do Intelecto na Idade Média’ que está em desenvovlimento no Centro Internacional de Estudos Medievais da UFU. Palavras-chaves: Unidade do intelecto; Imaginação; Intencionalidade; Luz intelectual e cognição. Theories of the Intellect in the Latin Middle Ages. De anima III, cap. 5 of Aristotle and his Medieval Tradition Abstract: In the chapter 5 of the III. Book of De anima (430a10-19) Aristotle distinguishes between the νοῦς ποιητικός (nous poietikós) called by the Latins intellectus agens (agent intellect) and the νοῦς παθητικός (nous pathetikós) called by the Latins intellectus passivus, or intellectus possibilis (possible intellect), most common technical and philosophical terms. The chapter 5 is of great importance not only to ancient philosophy and to the commentators of Aristotle’s works such as the commentaries of Theophrastus, Alexander of Aphrodisias, of Simplicius, and Themistius among others, but also to the philosophy of the Arabic World and the Latin Europe. One knows well that Aristotle does not have written a proper treatise on intellect; although there are several observations about the intellect in his works. Separate treatises begin with Al-Kindi, Al-Farabi, Avicenna, and especially Averroes, which Latin treatises as of Albert the Great, Thomas Aquinas, Siger of Brabant among others reflect in a critical as well as an affirmative sense. This article can be read as preliminary and preparatory observations to a bilingual (Latin-Portuguese) translation project of treatises corresponding to ‘Theories of Intellect in the Middle Ages’ which is ongoing at the International Center for Medieval Studies at UFU. Key-words: Unity of the Intellect; Imagination; Intentionality; Intellectual Light; and Cognition. Theorien des Intellekts im Lateinischen Mittelalter. De anima III, 5 des Aristoteles und seine mittelalterliche Tradition Zusammenfassung: Im 5. Kapitel des III. Buchs von De anima (430a10-19) unterscheidet Aristoteles zwischen dem νοῦς ποιητικός (nous poietikós), von den Lateinern intellectus agens (tätiger Intellekt) genannt und dem νοῦς παθητικός (nous pathetikós), von den Lateinern intellectus passivus oder auch intellectus possibilis (möglicher Intellekt) genannt, gemeinhin bekannte technische und philosophische Begriffe. Dieses 5. Kapitel ist von grösster Bedeutung nicht nur für die antike Philosophie und die Kommentatoren der Werke des Aristoteles wie die Kommentare des Theophrastus, des Alexander von Aphrodisias, Simplicius und Themistius unter anderen, sondern auch für die Philosophie der arabischen Welt und des lateinischen Europas. Bekanntlich hat Aristoteles keinen eigenen Traktat über den Intellekt geschrieben, obgleich sich viele Beobachtungen zum Intellekt in seinem Werk antreffen. Selbständige Traktate über den Intellekt beginnen mit Al-Kindi, Al-Farabi, Avicenna und besonders Averroes, die sich in den lateinischen Traktaten, z.B. des Albertus Magnus, Thomas von Aquin, Siger von Brabant und anderen zustimmend wie kritisch widerspiegeln. Dieser Artikel kann als vorläufige und vorbereitende Bemerkungen zu einem zweisprachigen (lateinisch-portugiesischen) Übersetzungsprojekt von Texten gelesen werden, welche „Theorien des Intellekts im Lateinischen Mittelalter“ betreffen. Dieses Projekt ist am Internationalen Zentrum für Mittelalterstudien der UFU in Arbeit genommen worden. Schlüsselwörter: Verstand; Vernunft; Intentionalität; Anschauung und Erkenntnis.

W spisanych przez L. Wittgensteina pod koniec życia Bemerkungen über die Farben znajdujemy kilka 'zagadek' dotyczących kolorów, np.: 1. „Jak to się dzieje, że coś przezroczystego może być zielone, ale nie może być białe". 2. „niepodobna sobie wyobrazić czystą białą wodę". 3. „Ale kolor świeci za sprawą swego otoczenia, w swym otoczeniu. Szary jednak nie świeci. 4. „? W obrazie biel musi być najjaśniejszym kolorem". „Nieprawda, że w obrazie biel zawsze musi być najjaśniejszym kolorem. Z pewnością jednak jest nim w (...) płaskiej kombinacji plam barwnych". 5. „Dlaczego nie ma brązowego światła ani szarego?" „Dlaczego niepodobna sobie wyobrazić szarego żaru". 6. „Czyż nie mogliby istnieć ludzie, dla których istnieje niebieskawy żółty, czerwonawy zielony? A zatem tacy ludzie, których pojecia o kolorach odbiegają od naszych pojęć?". (shrink)

The article concentrates on the analysis of the Enlightenment periods vision of science by Josef Sołtykowicz. His theories are examples of philosophical reflection of the Cracow Science Society. The starting point was the outline of the political and scientific situation from the second part of the XVII century to the first part of the XIX century also referring to the author’s biography. The main part of the article is the analysis of two Dissertations by Sołtykowicz published by the Cracow (...) Science Society their yearly publication, in 1818 and 1820. The following points were taken into account: The roots of the society’s activities, the relationship between science and faith, popularizing knowledge, criticism of Rousseau and anthropological analysis of the roots, of the negative view of knowledge. These theories are worth analysing, unfortunately so far the philosophical thought of the members of CSS, has not encouraged work on them as they deserved. At the same time we can expect that the work of the scientists from the CSS significantly impacted on the progress of the philosophical reflection in Cracow, and also the wider picture of modern polish scientific culture.

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)

Ingarden distinguishes four strata making up the structure of the literary work of art: the stratum of word sounds and sound-complexes; the stratum of meaning units; the stratum of represented objectivities (characters, actions, settings, and so forth); and the stratum of schematized aspects (perspectives under which the represented objectivities are given to the reader). It is not only works of literature which manifest this four-fold structure but also certain borderline cases such as newspaper articles, scientific works, biographies, and so forth. (...) Ingarden specifies what is characteristic of a work of literature by asserting that all declarative sentences appearing in the stratum of meaning units of such work possess what he calls a quasi-judgmental character. We discuss here Ingarden’s theory of quasi-judgments and draw out its implication that all works of literature are works of fiction through and through. (shrink)

In this volume the history of Islamic sects is analysed as a literary genus in its own right. It consists of three sections: the first deals with structural constants in the texts such as the arrangement, or the number and classification of the "sects." The main section describes the most important works and authors from the 8th to the 19th century. Finally, the central concepts - "religion," "sects," "orthodoxy," etc. - are considered and the historical background of the literary development (...) examined in more detail. It turns out that the "heresies" were rather "confessions" which can be understood as proof of the pluralistic structure of the Islamic community. (shrink)

We introduce the notion of a convex tree. We show that the binary expansion for real numbers in the unit interval ) is equivalent to weak König lemma ) for trees having at most two nodes at each level, and we prove that the intermediate value theorem is equivalent to \ for convex trees, in the framework of constructive reverse mathematics.

This paper addresses two issues: what it is for a metaphor to be either alive or dead and what a metaphor must be in order to be either alive or dead. Both issues, in turn, bear on the contemporary debate whether metaphor is a pragmatic or semantic phenomenon and on the dispute between Contextualists and Literalists. In the first part of the paper, I survey examples of what I take to be live metaphors and dead metaphors in order to establish (...) that there is a phenomenon here to be explained. I then propose an explanation of metaphorical vitality in terms of the dependence of the interpretation of a metaphor on a family or network of expressions specific to its context of utterance. I then argue that only a Literalist account of metaphor — one that posits metaphorical expressions )—and not Contextualist and Gricean approaches can accommodate this explanation. Finally, I discuss some objections to my Literalist account and sketch an explanation of types to counter Platonistic objections to my metaphorical expression types. (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)

A rigorous analysis of Maimonides' and Nahmanides' explanations of the Mosaic commandments that challenges received notions of the relation between these two seminal thinkers.

The approach of structuralism came to philosophy from social science. It was also in social science where, in 1950–1970s, in the form of the French structuralism, the approach gained its widest recognition. Since then, however, the approach fell out of favour in social science. Recently, structuralism is gaining currency in the philosophy of mathematics. After ascertaining that the two structuralisms indeed share a common core, the question stands whether general structuralism could not find its way back into social science. The (...) nature of the major objections raised against French structuralism – concerning its alleged ahistoricism, methodological holism and universalism – are reconsidered. While admittedly grounded as far as French structuralism is concerned, these objections do not affect general structuralism as such. The fate of French structuralism thus does not seem to preclude the return of general structuralism into social science, rather, it provides some hints where the difficulties may lie. (shrink)

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.

The relationship between science and philosophy is contentious. Quine saw philosophy as continuous with science (broadly understood), but many philosophers see a dichotomy between them. The present paper discusses cases where the relevance of certain scientific findings has been denied (related to Zeno’s Dichotomy paradox and to the appeal of skeptical arguments) or overlooked (one argument related to the frame problem of artificial intelligence and Nagel’s “bat” argument). The results caution against overly quick dismissal of the import of science on (...) philosophical questions, whether the latter be of a more theoretical or practical nature. (shrink)

Following conventional wisdom Theology as an academic discipline (taught at Universities) is something which developed only in the Middle Ages, or in a certain sense even as late as the 19th century. The present essay in contrast traces its origins to Classical Antiquity and outlines its development in early Christianity, especially with a view to institutions of higher education that existed in Late Antiquity, e. g. in rhetoric and philosophy. It concludes that there were forms of academic theological discourse in (...) Late Antiquity which were to become the basis of later developments in the discipline. (shrink)

A single theme runs through the three essays on St. Thomas gather in this book. It is the theme of mystery or, more exactly, the response of the searching human intellect to the fact of mystery. Both the fact and the response are suggested in a short biography of St. Thomas that forms the first essay and are then sketched out in detail by a presentation of the "negative element" in his philosophy. The third essay shows that contemporary Existentialism is (...) in basic agreement with the philosophia perennis on this fundamental element of philosophical thinking. (shrink)

Alois Riehl’s View of Friedrich Nietzsche and His Relationship with Elisabeth Förster-Nietzsche. Alois Riehl and Friedrich Nietzsche were contemporaries – both were born in the same year, 1844. But the philosophical paths they followed could hardly be more different. Nevertheless, Riehl recognized Nietzsche as one of the most important thinkers of his time. He was one of the first academic philosophers to devote a detailed analysis to Nietzsche’s writings. And Riehl saw in Nietzsche’s work a complementary counterpart to the scientific (...) philosophy that he developed in his Philosophical Criticism. At the heart of the present paper is a speech given by Riehl on October 15, 1903, on the occasion of the reopening of the Villa Silberblick and the unveiling of Max Klinger’s bust of Nietzsche. The argument is divided into three parts. First, it reconstructs the background to these events historically in light of the friendly relationship between Elisabeth Förster-Nietzsche and Riehl, as well as Riehl’s hesitation to give a speech. Second, Riehl’s ambivalent attitude in his reception of Nietzsche is analyzed through a close reading of his text. Third, the paper concludes with a final look at the specific event of October 15, 1903, based on historical material. (shrink)

Evidence for infants' sensitivity to behavior being goal oriented leaves it open as to whether they see such behavior as being designed to lead to an external goal or whether they see it, in addition, as being directed by an internal representation of the goal. We point out the difficulty of finding possible criteria for how infants or children view this matter.
