Ein eben erschienenes Buch „Der Typenbegriff im Lichte der neuen Logik“ (von C. Hempel und P. Oppenheim) wird zum Anlass genommen, methodologische Probleme der Verwendung von Typenbegriffen zu diskutieren. Drei verschiedene Arten von Attributen werden unterschieden : klassifizierende Merkmale, abstufbare Merkmale und Massgrössen. Abstuf- bare Begriffe können standardisiert werden. So entstandene Standards werden als Quasi-Typen bezeichnet. Echte Typen entstehen aus Merkmalkombinationen. Diese Kombinationen werden in einem Merkmalsraum vorgenommen mit Hilfe sogenannter Reduktionen. Drei Arten von Reduktionen werden unterschieden. Die für die (...) empirische Sozialforschung wichtigste Reduktion ist die pragmatische : sie fasst Klassen von Merkmalkombinationen so zusammen, wie es ein vorliegendes Erhebungsproblem erfordert. Im allgemeinen werden Typen intuitiv gebildet, und erst nachher wird die ihnen entsprechende Merkmalskombination aufgedeckt. Dieses Verfahren heisst Substruktion. An Beispielen wird seine Bedeutung für die Praxis dargestellt. Es wird betont, dass die typologischen Operationen (Reduktion, Substruktion und Transformationen) nichts darüber aussagen, was ein Typus ist und wie er gefunden wird. Sie weisen nur gewisse formale Eigenschaften auf, die allen typologischen Systemen gemeinsam sind.Un livre récemment paru „Le concept de type à la lumière de la nouvelle logique“ (de C. Hempel et P. Oppenheim : „Der Typenbegriff im Lichte der neuen Logik“ ) fournit Toccasion de discuter quelques-uns des problèmes que pose l'emploi des concepts de type. On distingue trois catégories de caractères : caractères classificatoires, caractères gradués et mesures de grandeur. Les concepts gradués peuvent être standardisés de telle manière que naissent des standards que l'on peut qualifier de quasi-types. Les types authentiques naissent par combinaison de caractères. Ces combinaisons s'opèrent dans un „lieu de caractères“ (Merkmalsraum) à l'aide d'un procédé nommé réduction. On distingue trois sortes de réduction. La réduction la plus importante pour la recherche sociale est la réduction pragmatique : elle embrasse des classes de caractères combinés en fonction des exigences d'une enquête donnée. En général, les types sont formés intuitivement, ensuite seulement on découvre la combinaison de caractères correspondante. Cette démarche s'appelle substruction. On en montre la signification pour la pratique dans une série d’exemples. On souligne que les opérations typologiques (réduction, substruction, transformations) ne nous permettent nullement de dire ce qu'est un type et comment il a été découvert. Elles indiquent seulement certains caractères formels qui sont communs à tous les systèmes typologiques. (shrink)

During the 1960s Paul F. Lazarsfeld, co-founder of the renowned Columbia school, worked to promote a useful new research methodology. This paper analyses these activities. In a series of papers, Lazarsfeld demonstrated that the roots of empirical research, the useful methodology he developed, lie in the work of early European scholars. Building on his belief that quantification does not need numbers, he showed that Hermann Conring, with his “classificatory statistics,” had predated Frédéric Le Play and his “ (...) family budgets” and Adolphe Quételet and his “probability statistics” by almost two centuries. In another paper he highlighted the importance of Max Weber’s empirical studies on agrarian and industrial workers within the frame of his life work. His seminars at Columbia University with Robert K. Merton and at the Sorbonne with Raymond Boudon opened up transatlantic cooperation on empirical research between New York and Paris for decades to come. (shrink)

Descartes is widely portrayed as the arch proponent of “the epistemological transparency of thought” (or simply, “Transparency”). The most promising version of this view—Transparency-through-Introspection—says that introspecting (i.e., inwardly attending to) a thought guarantees certain knowledge of that thought. But Descartes rejects this view and provides numerous counterexamples to it. I argue that, instead, Descartes’s theory of self-knowledge is just an application of his general theory of knowledge. According to his general theory, certain knowledge is acquired only through clear and distinct (...) intellection. Thus, in his view, certain knowledge of one’s thoughts is acquired only through clear and distinct intellection of one’s thoughts. Introspection is a form of intellection and it can be clear and distinct. Ordinarily, however, introspection isn’t clear and distinct but is instead confused with dubitable perceptions of bodies. To make introspection clear and distinct, we need to “sharply separate” it from all perceptions of bodies by doubting all perceptions of bodies. Without such radical doubt, introspection remains confused and we lack certain knowledge not just of the specific features of our thoughts, but even of the minimal claim that a thought exists. Far from being the high priest of Transparency, Descartes is radically opposed to it. (shrink)

In _Matter and Consciousness_, Paul Churchland presents a concise and contemporary overview of the philosophical issues surrounding the mind and explains the main theories and philosophical positions that have been proposed to solve them. Making the case for the relevance of theoretical and experimental results in neuroscience, cognitive science, and artificial intelligence for the philosophy of mind, Churchland reviews current developments in the cognitive sciences and offers a clear and accessible account of the connections to philosophy of mind. For (...) this third edition, the text has been updated and revised throughout. The changes range from references to the iPhone's "Siri" to expanded discussions of the work of such contemporary philosophers as David Chalmers, John Searle, and Thomas Nagel. Churchland describes new research in evolution, genetics, and visual neuroscience, among other areas, arguing that the philosophical significance of these new findings lies in the support they tend to give to the reductive and eliminative versions of materialism. Matter and Consciousness, written by the most distinguished theorist and commentator in the field, offers an authoritative summary and sourcebook for issues in philosophy of mind. It is suitable for use as an introductory undergraduate text. (shrink)

The options in a decision problem generally have outcomes with common features. Putting aside the common features simplifies deliberations, but the simplification requires a philosophical justification that this book provides.

This book demonstrates how children's imagination makes a continuing contribution to their cognitive and emotional development.

The twentieth century has witnessed an unprecedented 'crisis in the foundations of mathematics', featuring a world-famous paradox (Russell's Paradox), a challenge to 'classical' mathematics from a world-famous mathematician (the 'mathematical intuitionism' of Brouwer), a new foundational school (Hilbert's Formalism), and the profound incompleteness results of Kurt Gödel. In the same period, the cross-fertilization of mathematics and philosophy resulted in a new sort of 'mathematical philosophy', associated most notably (but in different ways) with Bertrand Russell, W. V. Quine, and Gödel himself, (...) and which remains at the focus of Anglo-Saxon philosophical discussion. The present collection brings together in a convenient form the seminal articles in the philosophy of mathematics by these and other major thinkers. It is a substantially revised version of the edition first published in 1964 and includes a revised bibliography. The volume will be welcomed as a major work of reference at this level in the field.

Zusammenfassungen der Referate in französischer Sprache.

An agent often does not have precise probabilities or utilities to guide resolution of a decision problem. I advance a principle of rationality for making decisions in such cases. To begin, I represent the doxastic and conative state of an agent with a set of pairs of a probability assignment and a utility assignment. Then I support a decision principle that allows any act that maximizes expected utility according to some pair of assignments in the set. Assuming that computation of (...) an option's expected utility uses comprehensive possible outcomes that include the option's risk, no consideration supports a stricter requirement. (shrink)

Schelling und Hegel benutzen in ihren philosophischen Texten mathematische und naturwissenschaftliche Modelle wie Unendlichkeit oder Gleichgewicht. Die Strukturen dieser Begriffe liefern einen Massstab fur den Vergleich der Positionen Schellings und Hegels, der fur Schellings Identitatsphilosophie und Hegels erste Jenaer Schriften durchgefuhrt wird. Als wichtigstes Resultat kann eine grundlegende Differenz zwischen beiden Positionen bereits um 1801 nachgewiesen und gezeigt werden, dass diese auf einer unterschiedlichen Auffassung der Rolle des Absoluten beruht.

Like Plato, Protagoras held that young children learn virtue from fine examples in poetry. Unlike Plato, Protagoras taught adults by correcting the diction of poets. In this paper I ask what his standard of correctness might be, and what benefit he intended his students to take from exercises in correction. If his standard of correctness is truth, then he may intend his students to learn by questioning the content of poems; that would be suggestive of Plato’s program in Republic III. (...) But his standard is more likely to be the accurate use of language; in that case he would intend his students to learn to express their thoughts clearly enough that their audience would understand what they were saying. That standard would be independent of the truth of what they are saying; and that would be a precursor to modern techniques by which we try to teach speaking and writing. Truth is not so easy to escape, however, and we shall see that Protagoras’ exercise must assume that the poet is trying to tell the truth. (shrink)
