This paper presents the Spanish translation of the only two texts of Franz Brentano which deal specifically with St. Thomas Aquinas. The first text is a section about St. Albert the Great and Aquinas in an article published during Brentano’s youth, “The History of Ecclesiastical Sciences” (1867). The second text is an article, “Thomas Aquinas” (1908), written at the end of his life. Both texts reveal the immense value that Brentano saw in Aquinas. They also show that he regarded (...) Aquinas mainly as an important interpreter of Aristotle rather than as a philosopher in his own right. Brentano’s approach here also gives us some insight into his own conception of philosophical hermeneutics. The differences between the two texts are evident; for instance, in the second one, there is a Brentano’s manipulation of Aquinas’ thought to justify his leaving the Catholic Faith. The texts are also preceded by a little introduction of mine. Original titles: «Geschichte der kirchlichen Wissenschaften», in: Johann Adam Möhler (ed.), 'Kirchengeschichte', Band 2 (Regensburg: Manz, 1867), pp. 550-556 and «Thomas von Aquin», 'Neue Freie Presse' 15683 (18/4/1908): 1-5.

Ingenieur- und Naturwissenschaften sind Knoten eines engen Beziehungsgeflechts, in dem Mensch und Gesellschaft, Natur und Kultur weitere Knoten sind. Entwicklungen in diesen beiden Bereichen haben somit stets Auswirkungen sowohl auf die anderen Knoten als auf das Beziehungsgeflecht als Ganzes. Ingenieur- und Naturwissenschaften sind als ars humana zudem stets eine Form menschlicher Handlung. Damit werden sie zu einem Schlüsselproblem der theoretischen und praktischen Philosophie. Denn der Mensch, seine Handlungen und seine Eingliederung in die Gesellschaft stehen ebenso wie die Natur und die (...) Kultur seit jeher im Zentrum philosophischer Untersuchungen. Die Philosophie vermag diese beiden Wissenschaftsbereiche zu fundieren und kritisch zu begleiten. Philosophie, Ingenieur- und Naturwissenschaften haben das Vermögen, sich gegenseitig zu befruchten. In Anbetracht der humanen, sozialen und ökologischen Probleme des 21. Jhds. ist die fachbereichsübergreifende und partnerschaftliche Zusammenarbeit dieser drei Schlüsselbereiche unabdingbar. Sie ist eine nicht hintergehbare Grundbedingung aller Entwicklungen, die den Anspruch erheben, nachhaltig zu sein und damit dem normativen Leitziel folgen, heutigen und zukünftigen Generationen bedingungslos ein menschenwürdiges Leben zu ermöglichen. Ingenieure und Naturwissenschaftler können dabei einen wesentlichen Beitrag leisten. Die folgenden zehn Thesen begründen die Bedeutung einer an Nachhaltigkeit orientierten philosophischen Grundbildung von Ingenieuren und Naturwissenschaftlern. (shrink)

Wie wollen und können wir die Zukunft gestalten? Wie die Herausforderungen, die technische Innovationen, Digitalisierung und Künstliche Intelligenz (KI) mit sich bringen, meistern? In diesem Band kommen Philosophen, Ingenieur- und Naturwissenschaftler ebenso zu Wort wie Juristen, Bildungswissenschaftler und Ökonomen. Sie alle blicken vom speziellen Standpunkt ihres Fachs auf die Gestaltung der Zukunft. Als Brücke erweist sich dabei die Philosophie, welche die verschiedenen Perspektiven verknüpft und eint. Das Selbstverständnis von APHIN, des wissenschaftlichen und gemeinnützigen Arbeitskreises philosophierender Ingenieure und Naturwissenschaftler, – die (...) Offenheit für die Fragen und Probleme des jeweils anderen – ist damit in allen Beiträgen gegenwärtig. (shrink)

Natur, Kultur und Technik – diese drei Begriffe konstituieren ein mannigfaltiges, komplexes Beziehungsgeflecht, in dessen Zentrum der Mensch und sein Handeln stehen. Wie wollen wir mit technologischen Innovationen und natürlichen Ressourcen umgehen? Lassen sich vermeintliche Gegensätze und Widersprüche auflösen? Und welche kulturelle Praxis kann uns dabei helfen? Fragen wie diese liegen an der Schnittstelle verschiedener Fachdisziplinen. Für die philosophische Reflexion sind sie daher in besonderer Weise fruchtbar. Die Autorinnen und Autoren dieses Bandes thematisieren unterschiedliche Aspekte des Dreigespanns Natur, Kultur und (...) Technik, darunter Bildung, Ernährung, Ethik, Evolution, Nachhaltigkeit, Normsetzung, Umweltmanagement und Willensfreiheit. Sie demonstrieren in ihren Beiträgen ein lebendiges interdisziplinäres Denken, wie es zum Selbstverständnis von APHIN, dem wissenschaftlichen und gemeinnützigen Arbeitskreis philosophierender Ingenieure und Naturwissenschaftler, gehört.

In the spirit of Fontenelle's "Dialogues des morts", Dorschel stages an imaginary conversation between 18th century composer Joseph Haydn and 20th century composer Anton von Webern. In the section of Hades reserved for composers, they confront their different musical poetics.

Diese Arbeit zeichnet die Schwierigkeit nach, die Franz Brentano zwischen der Begruendung der Sittlichkeit aus moralischem Gefuehl und der Begruendung aus Vernunftgruenden zeitlebens gehabt hat: Die Eroerterung eines Gefuehls verwandelt dieses unweigerlich in ein Konzept der Kommunikation, das nicht nur rationaler, vielmehr noch oeffentlicher Diskussion zugaenglich wird. Beschraenkt man aber die Quelle des moralischen Gefuehls UND den Verstand auf ein individuelles Subjekt, geraet man mit der Untersuchung der Evidenz der sittlichen Erkenntnis in die naemlichen Aporien wie Franz Brentano.

This is the introduction to volume IX of Brentano’s Complete Published Writings: Sämtliche veröffentlichte Schriften: Vermischte Schriften. Brentano’s writings reproduced in this volume provide a substantial complement to important aspects of Brentano's philosophy which are less explicit in the other works he published during his lifetime. This volume contains thirteen writings: three of them belong to the period of Würzburg, two to the Italian period, and the others belong to the period of his teaching in Vienna. They can be grouped (...) under three broad categories. The first corresponds to the theme of the future of philosophy and the philosophical prospects in the late nineteenth century. This issue is recurrent in Brentano's work and is to be found in several of his writings published in this volume, notably in his inaugural address at the University of Vienna, in which he seeks, among other things, to trace the sources of discouragement with respect to the state of philosophy at that time and to rehabilitate confidence and optimism in the future of philosophy. The second topic pertains to Brentano’s philosophy of the history of philosophy and in addition to the article already mentioned in which Brentano elaborates his theory of the four phases, the article „Was für ein Philosoph manchmal Epoche macht“ is an application of the principles of his philosophy of history to Plotinus’ philosophy. The last section entitled Reviews and circumstantial writings contains more circumstantial writings including four reviews, Brentano’s 1908 paper on Thomas von Aquin and a short polemical paper on research without prejudice. It includes „Der Atheismus und die Wissenschaft“ which is an anonymous article in which Brentano criticizes the author of an article published in a Vienna journal on the compatibility of theism with a philosophy that defines itself as science; the second is Brentano’s reply to a critical review of his Psychology by Adolf Horwicz, the third is a review of J. Delitzsch's book on Thomas von Aquinas , and the last is a significant review of a book by Franz Miklosich on the topic of subjektlose Sätze. (shrink)

Metaphysics and psychology are two of Brentano’s main areas of interest in philosophy. His first writings, the dissertation On the Several Senses of Being in Aristotle (1862) and the habilitation thesis, The Psychology of Aristotle (1867), bear witness to the duality of his concerns. As such, these works were not only significant contributions to the German Aristotelianism of the second half of the XIXth century, but they also played an important role in the development of Brentano’s later philosophy and in (...) defining his school of thought. At the same time, the dissertation, now celebrating the sesquicentennial of its first publication, was received beyond the immediate sphere of the Brentanian school, for its reading played a significant role in young Heidegger’s thought on being, and thus in his development of a new type of phenomenology, distinct from the Husserlian one. The studies comprising this volume examine the relevance of Brentano’s dissertation, of his metaphysics and psychology for contemporary philosophical research. Generally, the papers emphasize a tendency in Brentanian research, which has become more conspicuous in the last two decades, and can be described as a gradual shift in focus from the specific problems of Brentano’s late philosophy, towards his earlier philosophy, especially his first writings and manuscripts. Taking into account both Brentano’s published works, and the manuscripts of the dissertation and the Psychology, the contributions of this volume manage to emphasise unexplored aspects of Brentano’s philosophy and stand witness to the complexity and the historical dimension of a legacy whose richness still awaits full discovery. -/- Table of Contents -/- Ion Tănăsescu, Foreword Edoardo Fugali, Trendelenburg, Brentano und die Aristoteles-Renaissance in der deutschen Philosophie des 19.

Christian von Ehrenfels was a student of both Franz Brentano and Carl Menger and his thinking on value theory was inspired both by Brentano’s descriptive psychology and by the subjective theory of economic value advanced by Menger, the founder of the Austrian school of economics. Value, for Ehrenfels, is a function of desire, and we ascribe value to those things which we either do in fact desire, or would desire if we were not convinced of their existence. He asserts (...) that the needed theoretical understanding of values is to be achieved by generalizing economic laws of valuation to apply to value in general. The law of marginal utility, for example, is a law to the effect that the n+1st sample of a good which I receive is ceteris paribus less valuable than the nth sample (imagine that the samples in question are, for example, a series of identical ham sandwiches). The essay describes how Ehrenfels provides on this basis an account of the different types of values, both intrinsic and non-intrinsic. It outlines also Ehrenfels views on the problem of interpersonal value-comparisons and on the struggle for survival between different values of different types. (shrink)

Thomas Garrigue Masaryk, later founder and President of the Republic of Czechoslovakia, studied philosophy in the University of Vienna from 1872 to 1876, where he came under the powerful influence of Franz Brentano. We survey the role of Brentano’s philosophy, and especially of his ethics, in Masaryk’s life and work.

(3) Beide Theorien gehen von verschiedenen Geschichtsauffassungen aus: Comtes Theorie schließt die Geschichte der fundamentalen positiven Wissenschaften ein, die geradli- nig verläuft, stets aufwärts führt und durch keine gesetzmäßig auftretenden Verfallsphasen belastet wird, aber dennoch Stagnationen kennt . Dagegen bezieht sich Brentanos Theorie vorwiegend auf die Geschichte der Philo- (...) sophie, allerdings indirekt auch auf die schönen Künste . Dabei verlaufen die historischen Entwicklungen zyklisch und kennen Perioden des wissen- schaftlichen Auf- und Niederganges, die sich wiederholen . (4) Beide The- orien enthalten verschiedene Strategien, die auf eine grundlegende Erneu- erung der Philosophie abzielen . Für Comte gilt, dass die neue Philosophie positiv und unabhängig von der philosophischen Tradition arbeiten müsse .

Review of B. Vancamp, Untersuchungen zur handschriftlichen Überlieferung von Platons Menon, Palingenesia Band 97. Stuttgart: Franz Steiner Verlag, 2010.

There is a narrow thread in the vast literature on Kafka which pertains to Kafka’s knowledge of philosophy, and more precisely to Kafka’s use in his fictional writings of some of the main ideas of Franz Brentano. Kafka attended courses in philosophy at the Charles University given by Brentano’s students Anton Marty and Christian von Ehrenfels, and was for several years a member of a discussion-group organized by orthodox adherents of the Brentanian philosophy in Prague. The present essay summarizes (...) what is known about Kafka’s relations to the Brentanist movement. It draws on Brentanian ideas on the evidence of inner perception, on oblique consciousness, on active introspection, on correct and incorrect judgment, and on consciousness as a species of inner tribunal, in order to throw light on central features of Kafka’s writings, including stylistic features. Special attention is directed towards Die Verwandlung and Der Prozess, and a reading of the latter is offered according to which the trial of Joseph K. occurs entirely within the mind of K. himself. The revisions in the 1997 version of the paper relate especially to the treatment of Kafka and Brentano in Arnold Heidsieck’s book The Intellectual Contexts of Kafka’s Fiction: Philosophy, Law, Religion, of 1994.

Simulation (von lat. simulare, engl. simulation, franz. simulation, ital. simulazione), Bezeichnung für die Nachahmung eines Prozesses durch einen anderen Prozeß. Beide Prozesse laufen auf einem bestimmten System ab. Simuliertes u. simulierendes System (der Simulator in der Kybernetik) können dabei auf gleichen oder unterschiedlichen Substraten realisiert sein.

This essay illustrates the main aspects of the discussion between Brentano and Stumpf about «tonal fusion». In his Tonpsychologie, Stumpf essentially moved from a Brentanian standpoint. Yet, he did not adopt Brentano’s subsequently developed new theory of «sensible qualities», so that a polemic eventually arouse between them. Far from representing a marginal issue, the episode is relevant to our understanding of their relationship. The discussion as to the mechanism of tonal fusion reveals a general divergence between Brentano and Stumpf concerning (...) the idea of human sensibility as a whole and of the method of psychology.

Ein Beispiel für die Rezeption und Fortführung der schopenhauerschen Logik findet man in den Mathematiklehrbüchern Friedrich Adolph Wilhelm Diesterwegs (1790–1866), In diesem Aufsatz werden die historische und systematische Dimension dieser Anwendung von Logikdiagramme auf die Mathematik skizziert. In Kapitel 2 wird zunächst die frühe Rezeption der schopenhauerschen Logik und Philosophie der Mathematik vorgestellt. Dabei werden einige oftmals tradierte Vorurteile, die das Werk Schopenhauers betreffen, in Frage gestellt oder sogar ausgeräumt. In Kapitel 3 wird dann die Philosophie der Mathematik und der (...) Logik Schopenhauers vorgestellt. Es wird gezeigt, dass Schopenhauers Logikdiagramme auf Ideen der Mathematiker Leonhard Euler (1707–1783), Bernhard Friedrich Thibaut (1775–1832) und Franz Ferdinand Schweins (1780–1856) zurückgehen und dass Schopenhauer diese Logikdiagramme auch bereits zur Analyse mathematischer Begriffe verwendet. Kapitel 4 beschäftigt sich mit der Schopenhauer-Rezeption Diesterwegs. Es wird die Frage behandelt, inwieweit Diesterweg in der Mathematik von Schopenhauer beeinflusst war und welche Rolle dieser Einfluss auf sein Verständnis von Logik und Mathematik hatte. In Kapitel 5 wird schließlich gezeigt, dass Diesterweg die schopenhauersche Begriffsanalyse der Mathematik mit Hilfe von Logikdiagrammen aufgreift und weiterführt. Da Diesterweg einer der einflussreichsten Pädagogen und Mathematikdidaktiker des 20. Jahrhunderts war, ist anzunehmen, dass sich Spuren dieser Methode noch heute finden lassen. Inwiefern dies wahrscheinlich ist, wird in der Zusammenfassung (Kapitel 6) thematisiert. (shrink)

This book’s goal is to give an intellectual context for the following manuscript. -/- Includes bibliographical references and an index. Pages 1-123. 1). Philosophy. 2). Metaphysics. 3). Philosophy, German. 4). Philosophy, German -- 18th century. 5). Philosophy, German and Greek Influences Metaphysics. I. Hegel, Georg Wilhelm Friedrich -- 1770-1831 -- Das älteste Systemprogramm des deutschen Idealismus. II. Rosenzweig, Franz, -- 1886-1929. III. Schelling, Friedrich Wilhelm Joseph von, -- 1775-1854. IV. Hölderlin, Friedrich, -- 1770-1843. V. Ferrer, Daniel Fidel, 1952-. [Translation (...) from German into English of the-- Das älteste Systemprogramm des deutschen Idealismus.]. -/- Note: the manuscript is in the handwriting of G.W.F. Hegel, but the actual authorship is disputed. No date is given. Franz Rosenzweig made up the title as it is known today. He published the text in 1917. At that time, F. Rosenzweig thought F.W.J. Schelling was the author. No one has read this book for errors. As always, any errors, mistakes or oversights etc. are mine alone. Given a couple more years, I could improve this book. This is a philosophical translation and not a philological translation. Martin Luther who did the famous early translation of the Bible into German wrote in a letter, “If anyone does not like my translation, they can ignore it… (September 15, 1530)”. There are no ‘correct’ translations. Some are just better than other translations. -/- The Oldest Systematic Program of German Idealism. The German title is: Das Älteste Systemprogramm Des Deutschen Idealismus. This title was made up by Franz Rosenzweig in 1917, when he first published the manuscript. He found the manuscript in the Royal Library in Berlin in 1913. The manuscript suggested date is around 1796 and was done by handwriting research. However, the manuscript is not dated. The Prussian State Library auctioned in March 1913 from the auction of the house Liepmannssohn in Berlin a single sheet on the front and back with Hegel's cursive handwriting. The manuscript was lost during WWII. But Dieter Henrich found it again in 1979 in the “Biblioteka Jagiellonska” in Krakow (Poland), where it is today. Address: Jagiellonian Library, Jagiellonian University, al. Mickiewicza 22, 30-059 Cracow, Poland. Later research suggests that manuscript had come from the estate of Hegel’s student Friedrich Christoph Förster (1791-1868). He was one of the editors of Hegel’s posthumous works and most likely had access to a number of Hegel’s manuscripts. This text actually being one of them. Hegel traveled around Bohemia with Marie and Friedrich Christoph Förster around the year 1820-21 (see Klaus Vieweg). -/- Philosophical mystery -- who is the author or authors of this text? -/- Take a plunge into the deep and cold waters. Maybe a quagmire or quandary, but decidedly interesting. This project is to contextualize an old handwritten manuscript which is about 225 years old. The actual author is a mystery. I offer my own assessment. You can make your own assessments. The mystery has continued to unfold since 1917. There is plenty to read. Otherwise, think about the authorship and read more of the German philosophers and authors from this period and enjoy the depth of thinking and philosophizing. On one hand, there is just the sheer fun in the puzzle of the authorship questions; and on the other hand, these are the alluring thoughts that lead to the nascent stage of German Idealism and our intellectual heritage. There is no end to the accolades for this group of philosophers. A heritage that we still hear in in our attempts to move forward into our future. -/- Do your own astute exegesis (ἐξήγησις) as all paths are still open. Let your thought take to the wings of what is called thinking with this text. Critical encounters (Auseinandersetzung, or a Gegenüberstellung) with at least: Friedrich Hölderlin (1770-1843) Friedrich Wilhelm Joseph Schelling (1775-1854), and Georg Wilhelm Friedrich Hegel (1770-1831) --- starts here! German Idealism. We are not going to study this situation endlessly, instead we make some broad strokes and provide you a general context. You are allowed to read between the lines too. Goal: to understand the overall affinity and differences between the intellectuals of this period in German history; and to come to grips with this demanding text within its large scholarly context in the last 100 years. There are no final answers. (shrink)

● Sergio Cremaschi, The non-existing Island. I discuss the way in which the cleavage between the Continental and the Anglo-American philosophies originated, the (self-)images of both philosophical worlds, the converging rediscoveries from the Seventies, as well as recent ecumenic or anti-ecumenic strategies. I argue that pragmatism provides an important counter-instance to both the familiar self-images and to the fashionable ecumenic or anti-ecumenic strategies. My conclusions are: (i) the only place where Continental philosophy exists (as Euro-Communism one decade ago) is America; (...) (ii) less obviously, also analytic philosophy does not exist, or does no more exist as a current or a paradigm; what does exist is, on the one hand, philosophy of language and, on the other, philosophy of mind, that is, two disciplines; (iii) the dissolution of analytic philosophy as a school has been extremely fruitful, precisely in so far as it has left room for disciplines and research programmes; (iv) what is left, of the Anglo-American/Continental cleavage is primarily differences in styles, depending partly on intellectual traditions, partly owing to sociology, history, institutional frameworks; these differences should not be blurred by rash ecumenism; besides, theoretical differences are alive as ever, but within both camps; finally, there is indeed a lag (not a difference) in the appropriation of intellectual techniques by most schools of 'Continental' philosophy, and this should be overcome through appropriation of what the best 'analytic' philosophers have produced. ● Michael Strauss, Language and sense-perception: an aspect of analytic philosophy. To test an assertion about one fact by comparing it with perceived reality seems quite unproblematic. But the very possibility of such a procedure is incompatible with the intellectualistic basis of logical positivism and atomism (as it is for example to be found in Russell's Analysis of Mind). According to the intellectualistic approach pure sensation is meaningless. Sensation receives its meaning and order from the intellect through interpretation, which is performed with the help of linguistic tools, i.e. words and sentences. Before being interpreted, sensation is not a picture or a representation, it is neither true nor false, neither an illusion nor knowledge; it does not tell us anything; it is a lifeless and order-less matter. But how can a thought (or a proposition) be compared with such a lifeless matter? This difficulty confronts the intellectualist, if on the one hand he admits the necessity of comparing thought with sense-perception, and on the other hand presupposes that we possess only intellectual and no immediate perceptual understanding of what we see and hear. In this paper I give a critical exposition of three attempts, made by Russell, Neurath and Wittgenstein, to solve this problem. The first attempt adheres to strict conventionalism, the second tends to naturalism and the third leads to an amended, very moderate version of conventionalism. This amended conventionalism looks at sense impressions as being a peculiar language, which includes primary symbols, i.e. symbols not founded on convention and not being in need of interpretation. ● Ernst Tugendhat, Phenomenology and language analysis. The paper, first published in German in 1970, by which Tugendhat gave a start to the German rediscovery of analytic philosophy. The author stages a confrontation between phenomenology and language analysis. He argues that language analysis does not differ from phenomenology as far as the topics dealt with are concerned; instead, both currents are quite different in method. The author argues that language-analytic philosophy does not simply lay out of the mainstream of transcendental philosophy, but that instead it challenges this tradition on the very level of foundations. The author criticizes the linguistic-analytic approach centred on the subject as well as any object-centred approach, while proposing inter-subjective understanding through language as the new universal framework. This is, when construed in so general terms, the same program of hermeneutics, though in a more basic version. ● Jürgen Habermas, Language game, intention and meaning. On a few suggestions by Sellars and Wittgenstein. The paper, first published in German in 1975, in which Habermas announces his own linguistic turn through a discovery of speech acts. In this essay the author wants to work out a categorical framework for a communicative theory of society; he takes Wittgenstein's concept of language game as a Leitfade and, besides, he takes advantage also of Wilfried Sellars's quasi-transcendental account of the genesis of intentionality. His goal is to single out the problems connected with a theory of consciousness oriented in a logical-linguistic sense. ● Zvie Bar-On, Isomorphism of speech acts and intentional states. This essay presents the problem of the formal relationship between speech acts and intentional states as an essential part of the perennial philosophical question of the relation between language and thought. I attempt to show how this problem had been dealt with by two prominent philosophers of different camps in our century, Edmund Husserl and John Searle. Both of them wrote extensively about the theory of intentionality. I point out an interesting, as it were unintended, continuity of their work on that theory. Searle started where Husserl left off 80 years earlier. Their meeting point could be used as the first clue in our search. They both adopted in effect the same distinction between two basic aspects of the intentional experience: its content or matter, and its quality or mode. Husserl did not yet have the concept of a speech act as contradistinguished from an intentional state. The working hypothesis, however, which he suggested, could be used as a second clue for the further elaboration of the theory. The relationship of the two levels, the mental and the linguistic, which remained for Husserl in the background only, became the cornerstone of Searle' s inquiry. He employed the speech act as the model and analysed the intentional experience by means of the conceptual apparatus of his own theory of speech acts. This procedure enabled him to mark out a number of parallelisms and correlations between the two levels. This procedure explains the phenomenon of the partial isomorphism of speech acts and intentional states. ● Roberta de Monticelli, Ontology. A dialogue among the linguistic philosopher, the naturalist, and the phenomenological philosopher. This paper proposes a comparison between two main ways of conceiving the role and scope of that fundamental part of philosophy (or of "first" philosophy) which is traditionally called "ontology". One way, originated within the analytic tradition, consists of two main streams, namely philosophy of language and (contemporary) philosophy of mind, the former yielding "reduced ontology" and the latter "neo-Aristotelian ontology". The other way of conceiving ontology is exemplified by "phenomenological ontology" (more precisely, the Husserlian, not the Heideggerian version). Ontology as a theory of reference ("reduced" ontology, or ontology as depending on semantics) is presented and justified on the basis of some classical thesis of traditional philosophy of language (from Frege to Quine). "Reduced ontology" is shown to be identifiable with one level of a traditional, Aristotelian ontology, namely the one which corresponds to one of the four "senses of being" listed in Aristotle's Metaphysics: "being" as "being true". This identification is justified on the basis of Franz Brentano's "rules for translation" of the Aristotelian table of judgements in terms of (positive and negative) existential judgments such as are easily translatable into sentences of first order predicate logic. The second part of the paper is concerned with "neo-Aristotelian ontology", i.e. with naturalism and physicalism as the main ontological options underlying most of contemporary discussion in the philosophy of mind. The qualification of such options as "neo-Aristotelian" is justified; the relationships between "neo-Aristotelian ontology" and "reduced ontology" are discussed. In the third part the fundamental tenet of "phenomenological ontology" is identified by the thesis that a logical theory of existence and being does capture a sense of "existing" and "being" which, even though not the basic one, is grounded in the basic one. An attempt is done of further clarifying this "more basic" sense of "being". An argument making use of this supposedly "more basic" sense is advanced in favour of a "phenomenological ontology". ● Kuno Lorenz, Analytic Roots in Dialogic Constructivism. Both in the Vienna Circle ad in Russell's early philosophy the division of knowledge into two kinds (or two levels), perceptual and conceptual, plays a vital role. Constructivism in philosophy, in trying to provide a pragmatic foundation - a knowing-how - to perceptual as well as conceptual competences, discovered that this is dependent on semiotic tools. Therefore, the "principle of method" had to be amended by the "principle of dialogue". Analytic philosophy being an heir of classical empiricism, conceptually grasping the "given", and constructive philosophy being an heir of classical rationalism, perceptually providing the "constructed", merge into dialogical constructivism, a contemporary development of ideas derived especially from the works of Charles S. Peirce (his pragmatic maxim as a means of giving meaning to signs) and of Ludwig Wittgenstein (his language games as tools of comparison for understanding ways of life). 7. Albrecht Wellmer, "Autonomy of meaning" and "principle of charity" from the viewpoint of the pragmatics of language. In this essay I present an interpretation of the principle of the autonomy of meaning and of the principle of charity, the two main principles of Davidson's semantic view of truth, showing how both principles may fit in a perspective dictated by the pragmatics of language. I argue that (I) the principle of the autonomy of meaning may be thoroughly reformulated in terms of the pragmatics of language, (ii) the principle of charity needs a supplement in terms of pragmatics of language in order to become really enlightening as a principle of interpretation. Besides, I argue that: (i) on the one hand, the fundamental thesis of Habermas on the pragmatic theory of meaning ("we understand a speech act when we know what makes it admissible") is correlated with the seemingly intentionalist thesis according to which we understand a speech act when we know what a speaker means; (ii) on the other hand, to say that the meaning competence of a competent speaker is basically a competence about a potential of reasons (or also of possible justifications) which is inherently connected with the meaning of statements, or with their use in utterances. ● Rüdiger Bubner, The convergence of analytic and hermeneutic philosophy This paper argues that the analytic philosophy does not exist, at least as understood by its original programs. Differences in the analytic camp have always been bigger than they were believed to be. Now these differences are coming to the fore thanks to a process of dissolution of dogmatism. Philosophical analysis is led by its own inner logic towards questions that may be fairly qualified as hermeneutic. Recent developments in analytic philosophy, e.g. Davidson, seem to indicate a growing convergence of themes between philosophical analysis and hermeneutics; thus, the familiar opposition of Anglo-Saxon and Continental philosophy might soon belong to history. The fact of an ongoing appropriation of analytical techniques by present-day German philosophers may provide a basis for a powerful argument for the unity of philosophizing, beyond its strained images privileging one technique of thinking and rejecting the remainder. Actual philosophical practice should take the dialogue between the two camps more seriously; in fact, the processes described so far are no danger to philosophical work. They may be a danger for parochial approaches to philosophizing; indeed, contrary to what happens in the natural sciences, Thomas Kuhn's "normal science" developing within the framework of one fixed paradigm is not typical for philosophical thinking. And in philosophy innovating revolutions are symptoms more of vitality than of crisis. ● Karl-Otto Apel, The impact of analytic philosophy on my intellectual biography. In my paper I try to reconstruct the history of my Auseinandersetzung mit - as I called it - "language-analytical" philosophy (including even Peircean semiotics) since the late Fifties. The heuristics of my study was predetermined by two main motives of my beginnings: the hermeneutic turn of phenomenology and the transformation of "transcendental philosophy" in the light of the "language a priori". Thus, I took issue with the early and the later Wittgenstein, logical positivism, and post-Wittgensteinian and post-empiricist philosophy of science (i.e. G.H. von Wright and the renewal of the "explanation vs understanding controversy" as well as the debate between Th. Kuhn and Popper/Lakatos); besides, with speech act theory and the debate about "transcendental arguments" since Strawson. The "pragmatic turn", started already by C.L. Morris and the later Carnap, led me to study also the relationship between Wittgensteinian "use" theory of meaning and of truth. This resulted on my side in something like a program of "transcendental semiotics", i.e. "transcendental pragmatics" and "transcendental hermeneutics". ● Ben-Ami Scharfstein, A doubt on both their houses: the blindness to non-western philosophies. The burden of my criticism is that contemporary European philosophers of all kinds have continued to think as if there were no true philosophy but that of the West. For the most part, the existentialists have been oblivious of their Eastern congeners; the hermeneuticians have yet to stretch their horizons beyond the most familiar ones; and the analysts remain unaware of the analyses and linguistic sensitivities of the ancient non-European philosophers. Briefly, ignorance still blinds almost all contemporary Western philosophers to the rich, variegated philosophical traditions outside of their familiar orbit. Both Continental and Anglo-Americans have lost the breadth of view that once characterized such thinkers as Herder and the Humboldts. The blindness that has resulted is not simply that of individual Western philosophers but of our whole, still parochial philosophical culture. (shrink)

HISTÓRIA DA SOCIOLOGIA: O DESENVOLVIMENTO DA SOCIOLOGIA I -/- A SOCIOLOGIA NA ALEMANHA -/- -/- HISTORY OF SOCIOLOGY: THE DEVELOPMENT OF SOCIOLOGY I -/- SOCIOLOGY IN GERMANY -/- -/- -/- Emanuel Isaque Cordeiro da Silva – IFPE-BJ, CAP-UFPE e UFRPE. E-mail's: [email protected] e [email protected]. WhatsApp: (82)9.8143-8399. -/- PREMISSA -/- Na Alemanha, a Sociologia foi profundamente influenciada pela discussão filosófica, histórica e metodológica que se desenvolveu entre o final do século XIX e o início do século XX. Em seus fundamentos encontra-se (...) o pensamento de vários filósofos, como Johann Gottlieb Fichte (1762 -1814), Friedrich Wilhelm Joseph von Schelling (1775 -1854), Friedrich Daniel Ernst Schleiermacher (1768 -1834), Georg Wilhelm Friedrich Hegel (1770 -1831) e Friedrich W. Nietzsche (1844-1900). -/- O representante mais expressivo da Sociologia alemã é Max Weber (1864-1920). Outros pensadores, entretanto, contribuíram significativamente para a formação e o desenvolvimento da Sociologia na Alemanha, entre os quais Ferdinand Tönnies (1855 -1936), Werner Sombart (1863-1941), Georg Simmel (1858-1918) e os estudiosos que a partir da década de 1920 constituíram a chamada Escola de Frankfurt. -/- A obra desses autores liga-se fortemente ao processo de unificação alemã, promovido somente após o triunfo de Otto von Bismarck na Guerra Franco-Prussiana (1871), e à aceleração da industrialização alemã. Esses dois fatores conferiram à Alemanha uma situação muito diferente da de outros países europeus. -/- A alteração nas estruturas de poder, na Alemanha, não ocorreu por meio de uma revolução, como na França, mas por um acordo entre a bur-guesia industrial e os grandes proprietários de terra, tendo em vista uma transição mais adequada aos seus interesses. -/- Vale salientar, em nota, que após a Guerra Franco-Prussiana (1870-71), os príncipes alemães se reuniram no palácio de Versalhes (França), onde aclamaram Guilherme I, da Prússia, como o imperador alemão. Assim surgia o Império da Alemanha, em 1871. -/- A burguesia industrial não estava preocupada em alterar de modo significativo a estrutura fundiária, e os grandes proprietários, que se encastelaram na burocracia estatal, não permitiram a formulação de uma legislação trabalhista que prejudicasse os interesses da burguesia. Assim se fez uma mudança “por cima”, sem levar em conta os interesses dos trabalhadores urbanos ou rurais. Destacam-se aqui dois importantes soció-logos alemães: Georg Simmel e Max Weber, pela presença no Brasil. Depois, brevemente, falar-se-á aqui da famosa Escola de Frankfurt. -/- 1. Georg Simmel (1858-1918) -/- Nascido em Berlim, Georg Simmel é um pensador difícil de enquadrar em alguma tendência ou campo específico do conhecimento. Vamos ler um trecho do que escreveu sobre ele o sociólogo brasileiro Leopoldo Waizbort: -/- Quem tentar esboçar a fisionomia de Georg Simmel (1858-1918), logo se encontra em meio a dificuldades que são características próprias daquilo que se quer apreender. Simmel sempre postulou para seu próprio pensamento uma mobilidade e uma plasticidade para se adaptar ao seu objeto – uma multiplicidade de direções, uma defesa do fragmento –, que se opõem a toda tentativa de fixação e acabamento, a toda pretensão de sistema. Por isso todos os rótulos que lhe são atribuídos, apesar de possuírem seu teor de verdade, sempre soam tão falsos: vitalismo, relativismo, esteticismo, formalismo, irracionalismo, psicologismo, impressionismo e tantos mais. Disto também é exemplo o fato de Simmel, hoje considerado, ao lado de Max Weber e Ferdinand Tönnies, um dos “pais” da sociologia alemã, não poder ser classificado sem mais como “sociólogo”, sob pena de se perderem várias outras dimensões que são essenciais ao seu pensamento (WAIZBORT, 2000. p. 11). -/- G. Simmel foi o último dos sete filhos de um próspero comerciante judeu convertido ao cristianismo. Com a morte do pai, herdou uma fortuna considerável que lhe permitiu independência para desenvolver a vida acadêmica. Estudou História e Filosofia na Universidade de Berlim, onde foi aluno das mais importantes figuras acadêmicas da época. Em 1881, defendeu uma tese sobre Immanuel Kant e recebeu o título de doutor em Filosofia. Entre 1885 e 1914, lecionou Filosofia, Ética e Sociologia na Universidade de Berlim, mas nunca foi incorporado formalmente à universidade. -/- Ocupou o cargo de professor titular de Filosofia somente em 1914, em Estrasburgo, cidade onde permaneceu até a morte, em 1918. -/- Na virada do século XIX para o século XX na Alemanha, houve uma intensa efervescência filosófica, cultural e artística, cenário em que se desenvolveram a psicanálise, a teoria da relatividade, o positivismo lógico e a música atonal. Nesse cenário, Simmel tornou-se um conferencista muito aclamado e escreveu artigos e ensaios sobre os mais variados temas da Filosofia, como lógica, teoria do conhecimento, ética, estética ou metafísica, além de temas da Psicologia, da Sociologia, da História e da religião. -/- Escreveu também muitas biografias (de Johann Wolfgang von Goethe, de Friedrich Nietzsche, de Immanuel Kant e de Rembrandt, entre outros). -/- Suas obras sociológicas mais importantes são: Da diferenciação social (1890), A filosofia do dinheiro (1907), Sociologia (1908) e Questões fundamentais da Sociologia (1917). Georg Simmel teve influência marcante no desenvolvimento da Sociologia na Alemanha, nos Estados Unidos (em especial na Escola de Chicago) e na França (em Durkheim e seus colaboradores diretos). Suas obras foram traduzidas para o francês e o inglês, muitas vezes antes de ser publicadas em alemão. -/- 2. Max Weber (1864-1920) -/- Max Weber nasceu em 21 de abril de 1864, em Erfurt, e morreu em Munique, em 1920. De família abastada, teve uma educação formal de boa qualidade, o que lhe permitiu uma erudição notável. Com 18 anos, ingressou na Universidade de Heidelberg, onde escolheu como área de concentração o Direito e como correlatas a História, a Filosofia e a Economia. Nessa universidade, teve o primeiro contato com os escritos de Immanuel Kant e com neokantianos, os quais nunca deixou de lado em seus estudos. -/- Em 1889, concluiu o doutorado em Direito Comercial com uma tese sobre a história das sociedades comerciais da Idade Média. Em 1891, defendeu outra tese: A importância da história agrária romana para o direito público e privado. Em 1894, tornou-se professor de Economia na Universidade de Freiburg e, dois anos depois, transferiu-se para a Universidade de Heidelberg. -/- A partir de 1897, acometido de uma depressão profunda, não conseguiu desenvolver as atividades acadêmicas. Entre 1902 e 1903, retomou as atividades intelectuais, mas fora da universidade, pois não tinha condições psicológicas para ministrar aulas. No ano seguinte, tornou-se coeditor do Arquivo de Ciências Sociais, publicação muito importante para o desenvolvimento dos estudos sociológicos na Alemanha. -/- Entre agosto e dezembro de 1904, viajou, com Ferdinand Tönnies e Werner Sombart, aos Estados Unidos, por ocasião da Exposição Universal de Saint-Louis, onde entrou em contato com as igrejas e seitas protestantes daquele país e também com vários escritos de Benjamin Franklin (1706-1790), o que foi fundamental para suas pesquisas sobre a relação entre a ética protestante e o capitalismo. -/- Em 1907, recebeu uma herança significativa. A partir de então, dedicou-se exclusivamente à investigação histórica e sociológica. Em 1909, colaborou na fundação da Sociedade Alemã de Sociologia. Ao ser deflagrada a Primeira Guerra Mundial, em 1914, Weber foi convocado como oficial da reserva para dirigir um hospital militar. Entre as atividades no hospital encontrou tempo para continuar a escrever partes do livro que foi publicado postumamente por sua esposa, com o título Economia e sociedade. Além disso, desenvolveu estudos sobre ética econômica e as religiões universais e escreveu uma série de artigos para os grandes jornais da Alemanha. Nesses artigos, criticou a estrutura partidária do país e a burocratização das esferas políticas na Alemanha, afirmando que aquela situação ainda era a herança de Otto von Bismarck. -/- Em 1917, pronunciou uma conferência – A ciência como vocação – e produziu um escrito, no qual explicitou seu método – Ensaio sobre neutralidade axiológica nas ciências sociológicas e econômicas. -/- Pelas ideias expostas em debates e nos jornais e por sua erudição, Max Weber, após a derrota alemã na Primeira Guerra Mundial, fez parte da comissão que redigiu, em 1919, a nova constituição política alemã, conhecida como a Constituição de Weimar. -/- Pode-se afirmar que a vida de Max Weber foi dedicada aos estudos, à pesquisa e à participação ativa na política alemã de seu tempo, por meio de conferências e artigos para jornais e revistas. -/- Weber não media esforços para analisar e com-preender mais profundamente os temas que elegia. Aprendeu grego e hebraico para ler a Bíblia no original, espanhol para ler os documentos sobre as companhias de navegação e comércio espanhol, russo para ler os jornais sobre os acontecimentos na Rússia de 1905 até a revolução de 1917, inglês para ler os textos estadunidenses sobre a vida religiosa e a ética dos protestantes. -/- Para Max Weber, o indivíduo é o núcleo de análise por ser o único que pode definir intenções e finalidades para seus atos. Desse modo, o ponto de partida da Sociologia é a compreensão da ação dos indivíduos, atuando e vivenciando situações sociais com determinadas motivações e intenções. Instituições como Estado e família só ganham sentido quando vistas da perspectiva das relações sociais. Assim, Max Weber não concebe a sociedade como um bloco, uma estrutura una, mas como uma teia de relações capazes de produzir sentido. -/- A obra de Max Weber é vasta e engloba história, direito e economia, passando pelas questões religiosas, pelos processos burocráticos, pela análise da cidade, da música e, enfim, pela discussão metodológica das ciências humanas e dos conceitos sociológicos. -/- Entre os seus escritos, podemos destacar: A ética protestante e o “espírito” do capitalismo (1904-1905/1920), A ciência como vocação (1917), A política como vocação (1919), Economia e sociedade (1920), História geral da economia (1923) e Ensaios reunidos de sociologia da religião (1917/1920). -/- Outros sociólogos alemães mantiveram-se em atividade após a Primeira Guerra Mundial, como Ferdinand Tönnies, Leopold von Wiese (1876 -1969), Hans Freyer (1887-1969) e Franz Oppenheimer (1864 -1943), que fundou, em 1919, a primeira cátedra de Sociologia na Alemanha, em Frankfurt. -/- 3. A Escola de Frankfurt -/- Logo após a morte de Max Weber, abriu-se um novo horizonte para a Sociologia alemã com a fundação do Instituto de Pesquisa Social, vinculado à Universidade Johann Wolfgang Goethe de Frankfurt, que ficou conhecido como Escola de Frankfurt. Em 1923, um grupo de intelectuais – entre eles Friedrich Pollok (1894-1970), Leo Löwenthal (1900-1993), Karl August Wittfogel (1896-1988), Max Horkheimer (1895-1973) e Theodor Adorno (1903-1969) – desenvolveu uma análise da sociedade contemporânea com base em concepções filosóficas de Immanuel Kant, Friedrich Hegel e Friedrich Nietzsche, em visões sociológicas de Karl Marx e de Max Weber e no pensamento de Sigmund Freud. -/- Os integrantes do grupo de Frankfurt pretendiam desenvolver uma teoria crítica da sociedade capitalista e buscavam explicar fenômenos que iam da análise da personalidade autoritária à indústria cultural. Mantiveram a crítica ao positivismo e ao pragmatismo, procurando demonstrar a necessida-de de refletir sobre as condições que permitiram a emergência do nazismo e sobre o significado dessa ideologia. As reflexões desses intelectuais culminaram com uma crítica à razão instrumental e às formas de controle sobre a sociedade contemporânea. -/- Além dos estudiosos citados, são representantes desse pensamento Walter Benjamin (1892-1940), Erich Fromm (1900-1980) e Herbert Marcuse (1898-1979), entre outros. Todos os integrantes da Escola de Frankfurt precisaram sair da Alema-nha por causa da perseguição nazista. Adorno e Horkheimer voltaram ao país depois do fim da Segunda Guerra Mundial. Deram continuidade à Escola de Frankfurt, entre outros, Jürgen Habermas (1929-), da segunda geração, e Axel Honneth (1949-), da terceira e atual geração. -/- REFERENCIAL TEÓRICO -/- CUIN, C.

I present a formal theory of the logic and aboutness of imagination. Aboutness is understood as the relation between meaningful items and what they concern, as per Yablo and Fine’s works on the notion. Imagination is understood as per Chalmers’ positive conceivability: the intentional state of a subject who conceives that p by imagining a situation—a configuration of objects and properties—verifying p. So far aboutness theory has been developed mainly for linguistic representation, but it is natural to extend it to (...) intentional states. The proposed framework combines a modal semantics with a mereology of contents: imagination operators are understood as variably strict quantifiers over worlds with a content-preservation constraint. (shrink)

When one thinks—knows, believes, imagines—that something is the case, one’s thought has a topic: it is about something, towards which one’s mind is directed. What is the logic of thought, so understood? This book begins to explore the idea that, to answer the question, we should take topics seriously. It proposes a hyperintensional account of the propositional contents of thought, arguing that these are individuated not only by the set of possible worlds at which they are true, but also by (...) their topic: what they are about. The book then builds epistemic, doxastic, probabilistic, and conditional logics based on this view. It applies them to issues ranging from dogmatism, scepticism, and epistemic fallibilism, to imagination and suppositional reasoning, belief revision, framing effects, and the acceptability of indicative conditionals. (shrink)

We propose a new account of indicative conditionals, giving acceptability and logical closure conditions for them. We start from Adams’ Thesis: the claim that the acceptability of a simple indicative equals the corresponding conditional probability. The Thesis is widely endorsed, but arguably false and refuted by empirical research. To fix it, we submit, we need a relevance constraint: we accept a simple conditional 'If φ, then ψ' to the extent that (i) the conditional probability p(ψ|φ) is high, provided that (ii) (...) φ is relevant for ψ. How (i) should work is well-understood. It is (ii) that holds the key to improve our understanding of conditionals. Our account has (i) a probabilistic component, using Popper functions; (ii) a relevance component, given via an algebraic structure of topics or subject matters. We present a probabilistic logic for simple indicatives, and argue that its (in)validities are both theoretically desirable and in line with empirical results on how people reason with conditionals.

Public reason as a political ideal aims to reconcile reasonable disagreement; however, is public reason itself the object of reasonable disagreement? Jonathan Quong, David Estlund, Andrew Lister, and some other philosophers maintain that public reason is beyond reasonable disagreement. I argue this view is untenable. In addition, I consider briefly whether or not two main versions of the public reason principle, namely, the consensus version and the convergence version, need to satisfy their own requirements. My discussion has several important implications (...) for the debate on public reason. (shrink)

Behaviourism is the view that preferences, beliefs, and other mental states in social-scientific theories are nothing but constructs re-describing people's behaviour. Mentalism is the view that they capture real phenomena, on a par with the unobservables in science, such as electrons and electromagnetic fields. While behaviourism has gone out of fashion in psychology, it remains influential in economics, especially in ‘revealed preference’ theory. We defend mentalism in economics, construed as a positive science, and show that it fits best scientific practice. (...) We distinguish mentalism from, and reject, the radical neuroeconomic view that behaviour should be explained in terms of brain processes, as distinct from mental states. (shrink)

In response to recent work on the aggregation of individual judgments on logically connected propositions into collective judgments, it is often asked whether judgment aggregation is a special case of Arrowian preference aggregation. We argue for the converse claim. After proving two impossibility theorems on judgment aggregation (using "systematicity" and "independence" conditions, respectively), we construct an embedding of preference aggregation into judgment aggregation and prove Arrow’s theorem (stated for strict preferences) as a corollary of our second result. Although we thereby (...) provide a new proof of Arrow’s theorem, our main aim is to identify the analogue of Arrow’s theorem in judgment aggregation, to clarify the relation between judgment and preference aggregation, and to illustrate the generality of the judgment aggregation model.

Confucian scholars should satisfy two conditions insofar as they think their theories enable Confucianism to make contributions to liberal politics and social policy. The liberal accommodation condition stipulates that the theory in question should accommodate as many reasonable conceptions of the good and religious doctrines as possible while the intelligibility condition stipulates that the theory must have a recognizable Confucian character. By and large, Joseph Chan’s Confucian perfectionism is able to satisfy the above two conditions. However, contrary to Chan and (...) many other Confucian scholars, I argue that any active promotion of Confucianism will violate the liberal accommodation condition. I propose the “wide view of moderate perfectionism,” which enables Confucianism to shed light on a wide range of political and social issues without promoting Confucianism actively. Thus, I present a new approach to the long-standing question of how Confucianism may improve political and social development in a liberal society. (shrink)

The aggregation of individual judgments over interrelated propositions is a newly arising field of social choice theory. I introduce several independence conditions on judgment aggregation rules, each of which protects against a specific type of manipulation by agenda setters or voters. I derive impossibility theorems whereby these independence conditions are incompatible with certain minimal requirements. Unlike earlier impossibility results, the main result here holds for any (non-trivial) agenda. However, independence conditions arguably undermine the logical structure of judgment aggregation. I therefore (...) suggest restricting independence to premises, which leads to a generalised premise-based procedure. This procedure is proven to be possible if the premises are logically independent. (shrink)

Introduction and translation of “The Four Phases of Philosophy” by Franz Brentano.

The new field of judgment aggregation aims to merge many individual sets of judgments on logically interconnected propositions into a single collective set of judgments on these propositions. Judgment aggregation has commonly been studied using classical propositional logic, with a limited expressive power and a problematic representation of conditional statements ("if P then Q") as material conditionals. In this methodological paper, I present a simple unified model of judgment aggregation in general logics. I show how many realistic decision problems can (...) be represented in it. This includes decision problems expressed in languages of classical propositional logic, predicate logic (e.g. preference aggregation problems), modal or conditional logics, and some multi-valued or fuzzy logics. I provide a list of simple tools for working with general logics, and I prove impossibility results that generalise earlier theorems. (shrink)

John Broome has developed an account of rationality and reasoning which gives philosophical foundations for choice theory and the psychology of rational agents. We formalize his account into a model that differs from ordinary choice-theoretic models through focusing on psychology and the reasoning process. Within that model, we ask Broome’s central question of whether reasoning can make us more rational: whether it allows us to acquire transitive preferences, consistent beliefs, non-akratic intentions, and so on. We identify three structural types of (...) rationality requirements: consistency requirements, completeness requirements, and closedness requirements. Many standard rationality requirements fall under this typology. Based on three theorems, we argue that reasoning is successful in achieving closedness requirements, but not in achieving consistency or completeness requirements. We assess how far our negative results reveal gaps in Broome's theory, or deficiencies in choice theory and behavioral economics. (shrink)

A group is often construed as one agent with its own probabilistic beliefs (credences), which are obtained by aggregating those of the individuals, for instance through averaging. In their celebrated “Groupthink”, Russell et al. (2015) require group credences to undergo Bayesian revision whenever new information is learnt, i.e., whenever individual credences undergo Bayesian revision based on this information. To obtain a fully Bayesian group, one should often extend this requirement to non-public or even private information (learnt by not all or (...) just one individual), or to non-representable information (not representable by any event in the domain where credences are held). I pro- pose a taxonomy of six types of ‘group Bayesianism’. They differ in the information for which Bayesian revision of group credences is required: public representable information, private representable information, public non-representable information, etc. Six corre- sponding theorems establish how individual credences must (not) be aggregated to ensure group Bayesianism of any type, respectively. Aggregating through standard averaging is never permitted; instead, different forms of geometric averaging must be used. One theorem—that for public representable information—is essentially Russell et al.’s central result (with minor corrections). Another theorem—that for public non-representable information—fills a gap in the theory of externally Bayesian opinion pooling. (shrink)

Much of contemporary political philosophy revolves around debates over perfectionism, which is the view that the state may, or should, promote valuable conceptions of the good life and discourage conceptions that are worthless or bad. Collis Tahzib has recently proposed a unique theory of perfectionism. I examine two central aspects of his theory: the amalgamation of public reason and perfectionism, and the employment of the Rawlsian lexical priority. I argue that Tahzib’s idea of perfectionist public reason has certain serious problems. (...) Additionally, Tahzib, like many other perfectionists, has neglected that many excellences are at once personal and civic. I sketch a perfectionist account of civic virtue, with the hope of opening up space for defending and justifying perfectionism. (shrink)

There is a surprising disconnect between formal rational choice theory and philosophical work on reasons. The one is silent on the role of reasons in rational choices, the other rarely engages with the formal models of decision problems used by social scientists. To bridge this gap, we propose a new, reason-based theory of rational choice. At its core is an account of preference formation, according to which an agent’s preferences are determined by his or her motivating reasons, together with a (...) ‘weighing relation’ between different combinations of reasons. By explaining how someone’s preferences may vary with changes in his or her motivating reasons, our theory illuminates the relationship between deliberation about reasons and rational choices. Although primarily positive, the theory can also help us think about how those preferences and choices ought to respond to normative reasons. (shrink)

The contemporary theory of epistemic democracy often draws on the Condorcet Jury Theorem to formally justify the ‘wisdom of crowds’. But this theorem is inapplicable in its current form, since one of its premises – voter independence – is notoriously violated. This premise carries responsibility for the theorem's misleading conclusion that ‘large crowds are infallible’. We prove a more useful jury theorem: under defensible premises, ‘large crowds are fallible but better than small groups’. This theorem rehabilitates the importance of deliberation (...) and education, which appear inessential in the classical jury framework. Our theorem is related to Ladha's (1993) seminal jury theorem for interchangeable (‘indistinguishable’) voters based on de Finetti's Theorem. We also prove a more general and simpler such jury theorem. (shrink)

Which rules for aggregating judgments on logically connected propositions are manipulable and which not? In this paper, we introduce a preference-free concept of non-manipulability and contrast it with a preference-theoretic concept of strategy-proofness. We characterize all non-manipulable and all strategy-proof judgment aggregation rules and prove an impossibility theorem similar to the Gibbard--Satterthwaite theorem. We also discuss weaker forms of non-manipulability and strategy-proofness. Comparing two frequently discussed aggregation rules, we show that “conclusion-based voting” is less vulnerable to manipulation than “premise-based voting”, (...) which is strategy-proof only for “reason-oriented” individuals. Surprisingly, for “outcome-oriented” individuals, the two rules are strategically equivalent, generating identical judgments in equilibrium. Our results introduce game-theoretic considerations into judgment aggregation and have implications for debates on deliberative democracy. (shrink)

Degrees of belief are familiar to all of us. Our confidence in the truth of some propositions is higher than our confidence in the truth of other propositions. We are pretty confident that our computers will boot when we push their power button, but we are much more confident that the sun will rise tomorrow. Degrees of belief formally represent the strength with which we believe the truth of various propositions. The higher an agent’s degree of belief for a particular (...) proposition, the higher her confidence in the truth of that proposition. For instance, Sophia’s degree of belief that it will be sunny in Vienna tomorrow might be .52, whereas her degree of belief that the train will leave on time might be .23. The precise meaning of these statements depends, of course, on the underlying theory of degrees of belief. These theories offer a formal tool to measure degrees of belief, to investigate the relations between various degrees of belief in different propositions, and to normatively evaluate degrees of belief.

Under the independence and competence assumptions of Condorcet’s classical jury model, the probability of a correct majority decision converges to certainty as the jury size increases, a seemingly unrealistic result. Using Bayesian networks, we argue that the model’s independence assumption requires that the state of the world (guilty or not guilty) is the latest common cause of all jurors’ votes. But often – arguably in all courtroom cases and in many expert panels – the latest such common cause is a (...) shared ‘body of evidence’ observed by the jurors. In the corresponding Bayesian network, the votes are direct descendants not of the state of the world, but of the body of evidence, which in turn is a direct descendant of the state of the world. We develop a model of jury decisions based on this Bayesian network. Our model permits the possibility of misleading evidence, even for a maximally competent observer, which cannot easily be accommodated in the classical model. We prove that (i) the probability of a correct majority verdict converges to the probability that the body of evidence is not misleading, a value typically below 1; (ii) depending on the required threshold of ‘no reasonable doubt’, it may be impossible, even in an arbitrarily large jury, to establish guilt of a defendant ‘beyond any reasonable doubt’.

Timothy Williamson has defended the claim that the semantics of the indicative ‘if’ is given by the material conditional. Putative counterexamples can be handled by better understanding the role played in our assessment of indicatives by a fallible cognitive heuristic, called the Suppositional Procedure. Williamson’s Suppositional Conjecture has it that the Suppositional Procedure is humans’ primary way of prospectively assessing conditionals. This paper raises some doubts on the Suppositional Procedure and Conjecture.

I propose a relevance-based independence axiom on how to aggregate individual yes/no judgments on given propositions into collective judgments: the collective judgment on a proposition depends only on people’s judgments on propositions which are relevant to that proposition. This axiom contrasts with the classical independence axiom: the collective judgment on a proposition depends only on people’s judgments on the same proposition. I generalize the premise-based rule and the sequential-priority rule to an arbitrary priority order of the propositions, instead of a (...) dichotomous premise/conclusion order resp. a linear priority order. I prove four impossibility theorems on relevance-based aggregation. One theorem simultaneously generalizes Arrow’s Theorem (in its general and indifference-free versions) and the well-known Arrow-like theorem in judgment aggregation. (shrink)

Several recent results on the aggregation of judgments over logically connected propositions show that, under certain conditions, dictatorships are the only propositionwise aggregation functions generating fully rational (i.e., complete and consistent) collective judgments. A frequently mentioned route to avoid dictatorships is to allow incomplete collective judgments. We show that this route does not lead very far: we obtain oligarchies rather than dictatorships if instead of full rationality we merely require that collective judgments be deductively closed, arguably a minimal condition of (...) rationality, compatible even with empty judgment sets. We derive several characterizations of oligarchies and provide illustrative applications to Arrowian preference aggregation and Kasher and Rubinsteinís group identification problem. (shrink)

The widely discussed "discursive dilemma" shows that majority voting in a group of individuals on logically connected propositions may produce irrational collective judgments. We generalize majority voting by considering quota rules, which accept each proposition if and only if the number of individuals accepting it exceeds a given threshold, where different thresholds may be used for different propositions. After characterizing quota rules, we prove necessary and sufficient conditions on the required thresholds for various collective rationality requirements. We also consider sequential (...) quota rules, which ensure collective rationality by adjudicating propositions sequentially and letting earlier judgments constrain later ones. Sequential rules may be path-dependent and strategically manipulable. We characterize path-independence and prove its essential equivalence to strategy-proofness. Our results shed light on the rationality of simple-, super-, and sub-majoritarian decision-making. (shrink)

Suppose several individuals (e.g., experts on a panel) each assign probabilities to some events. How can these individual probability assignments be aggregated into a single collective probability assignment? This article reviews several proposed solutions to this problem. We focus on three salient proposals: linear pooling (the weighted or unweighted linear averaging of probabilities), geometric pooling (the weighted or unweighted geometric averaging of probabilities), and multiplicative pooling (where probabilities are multiplied rather than averaged). We present axiomatic characterisations of each class of (...) pooling functions (most of them classic, but one new) and argue that linear pooling can be justified procedurally, but not epistemically, while the other two pooling methods can be justified epistemically. The choice between them, in turn, depends on whether the individuals' probability assignments are based on shared information or on private information. We conclude by mentioning a number of other pooling methods. (shrink)

Was ist Nachhaltigkeit, was ist ihr Wesen und was bedeutet Nachhaltigkeit für Mensch und Gesellschaft, für Natur und Kultur? Um diese Fragen zu beantworten, lädt Jürgen H. Franz seine Leser zu einer philosophischen Reise ein. Die Reise führt zu den begriflichen Wurzeln und den Grundbedingungen der Nachhaltigkeit und eröffnet dabei sowohl einen Blick auf ihre globale Relevanz als auch auf die vielfältigen Hindernisse, die sich ihrer Realisierung entgegenstellen. Sie führt etappenweise zu immer neuen Standpunkten und damit zu neuen Ansichten (...) und Einsichten. Die Reise schließt auch ein historisches Etappenziel ein. Es ist die Zeit des Philosophen und Theologen Cusanus, der sich als ein früher Wegbereiter der Nachhaltigkeit erweist. Schritt für Schritt offenbart sich dem Reisenden die humane, moralische, soziale, ökologische, ökonomische, technische und historische Dimension der Nachhaltigkeit. Er lernt ein neues Modell der Nachhaltigkeit kennen, die Crux des Denkens in Systemen und die Idee einer Hermeneutik der Natur. Und er lernt zwei ungleiche Verwandte kennen: die Menschlichkeit und die Scheinheiligkeit. Am Ende seiner Reise vermag er Sein und Schein der Nachhaltigkeit zu trennen und ein eigenes Bild nachhaltiger Entwicklungen zu zeichnen. Seine Reiseerfahrungen bereichern seinen Alltag, sein Berufsleben oder Studium. (shrink)

In the framework of judgment aggregation, we assume that some formulas of the agenda are singled out as premisses, and that both Independence (formula-wise aggregation) and Unanimity Preservation hold for them. Whether premiss-based aggregation thus defined is compatible with conclusion-based aggregation, as defined by Unanimity Preservation on the non-premisses, depends on how the premisses are logically connected, both among themselves and with other formulas. We state necessary and sufficient conditions under which the combination of both approaches leads to dictatorship (resp. (...) oligarchy), either just on the premisses or on the whole agenda. This framework is inspired by the doctrinal paradox of legal theory and arguably relevant to this field as well as political science and political economy. When the set of premisses coincides with the whole agenda, a limiting case of our assumptions, we obtain several existing results in judgment aggregation theory. (shrink)

The paper provides an argument for the thesis that an agent’s degrees of disbelief should obey the ranking calculus. This Consistency Argument is based on the Consistency Theorem. The latter says that an agent’s belief set is and will always be consistent and deductively closed iff her degrees of entrenchment satisfy the ranking axioms and are updated according to the ranktheoretic update rules.

We present a new “reason-based” approach to the formal representation of moral theories, drawing on recent decision-theoretic work. We show that any moral theory within a very large class can be represented in terms of two parameters: a specification of which properties of the objects of moral choice matter in any given context, and a specification of how these properties matter. Reason-based representations provide a very general taxonomy of moral theories, as differences among theories can be attributed to differences in (...) their two key parameters. We can thus formalize several distinctions, such as between consequentialist and non-consequentialist theories, between universalist and relativist theories, between agent-neutral and agent-relative theories, between monistic and pluralistic theories, between atomistic and holistic theories, and between theories with a teleological structure and those without. Reason-based representations also shed light on an important but under-appreciated phenomenon: the “underdetermination of moral theory by deontic content”. (shrink)
