A rationalist and realist model of scientific revolutions will be constructed by reference to two categories of criteria of theory-evaluation, denominated indicators of truth and of beauty. Whereas indicators of truth are formulateda priori and thus unite science in the pursuit of verisimilitude, aesthetic criteria are inductive constructs which lag behind the progression of theories in truthlikeness. Revolutions occur when the evaluative divergence between the two categories of criteria proves too wide to be recomposed or overlooked. This model of revolutions (...) depends upon a substantial new treatment of aesthetic criteria in science with which much of the paper will therefore be occupied. (shrink)

Almost all commentators acknowledge that among the grounds on which scientists perform theory-choices are criteria of simplicity. In general, simplicity is regarded either as only a logico-empirical quality of a theory, diagnostic of the theory's future predictive success, or as a purely aesthetic or otherwise extra-empirical property of it. This paper attempts to demonstrate that the simplicity-criteria applied in scientific practice include both a logico-empirical and a quasi-aesthetic criterion: to conflate these in an account of scientists' theory-choice is to court (...) confusion.

The desire to minimize the number of individual new entities postulated is often referred to as quantitative parsimony. Its influence on the default hypotheses formulated by scientists seems undeniable. I argue that there is a wide class of cases for which the preference for quantitatively parsimonious hypotheses is demonstrably rational. The justification, in a nutshell, is that such hypotheses have greater explanatory power than less parsimonious alternatives. My analysis is restricted to a class of cases I shall refer to as (...) additive. Such cases involve the postulation of a collection of qualitatively identical individual objects which collectively explain some particular observed phenomenon. Especially clear examples of this sort occur in particle physics. 1 Introduction 2 Particle physics: a case study 3 Three kinds of simplicity 4 Explanatory power 5 Explanation and non-observation 6 Parsimony and scientific methodology 7 Conclusions.

Determinism has long been a core assumption in many forms of behaviorism, including radical behaviorism. However, this assumption has been a stumbling block for many—both within and outside the field of radical behaviorism—resulting in misunderstanding and misrepresentation. The following paper provides a descriptive taxonomy of four kinds of determinism assumed or asserted in the radical behavioral literature. This taxonomy is intended to organize these deterministic positions, provide working definitions, and explore their implications. Through this work, it is hoped that behaviorists (...) and nonbehaviorists alike will possess a clearer understanding of determinism in behavioral analysis. (shrink)

It is a matter of record that Henri Poincaré never responded publicly to Einstein's Special Theory of Relativity (RT). Since almost no private papers of Poincaré are available, his attitude toward Einstein's work and his silence on that score become somewhat of a mystery. It is almost certain that Poincaré knew of Einstein's work in RT. First, he was fluent in German, having learned it as a young man when the Germans occupied his home town of Nancy in 1870. Second, (...) he often reported to the members of theAcadémie des Scienceson current work in electrodynamics in Germany. It is highly improbable that he would have missed the abstract of Einstein's first paper on RT or the subsequent articles by Einstein on the subject, especially those which were translated into French, since they were in areas directly related to his own interests in theoretical physics.

One of the most significant trends within linguistics in the 1970s has been the move away from the formalised models of language introduced by Chomsky towards an account of language that incorporates functional premises. As Charles Fillmore put it, in a 1972 paper, the emphasis on formalisation needs to be balanced by a consideration of what exactly it is that linguists want to formalise. Putting this another way, a contrast can be drawn between the stress laid in the 1960s on (...) the specification in formal terms of the common factors that underlie utterances and the stress laid in the 1970s on the specification in functional terms of the differences between language forms, as captured by such notions as dialect, style, level, etc. (shrink)

Idealized explanations are the one subtype of incomplete explanations which is most frequently used in the empirical sciences and at the same time least analyzed in philosphy of sicence. It is argued that idealized explanations, while having the same logical structure as adequate explanations, differ from these in the mode of validity of the argument. Whereas an adequate explanation shows why the occurrence of some event had to be expected, an idealized explanation argues that a certain event would occur if (...) certain conditions were fulfilled. Idealized explanations are heuristic devices which, in the long run, ought to be transformed into adequate explanations. (shrink)

Die Frage, ob die Gültigkeit alternativer begrifflicher Strukturen empirisch entscheidbar oder eine Sache der willkürlichen Festsetzung ist, wird, eingeschränkt auf den Fall der physikalischen Geometrie, diskutiert. Die erkenntnistheoretischen Komponenten der empirischen Bestimmung von metrischen und topologischen Eigenschaften des physikalischen Raumes werden in der neueren Wissenschaftstheorie verfolgt. In Anschluß an die Auseinandersetzung zwischen A. Grünbaum und H. Putnam wird eine Interpretation des semantischen Status des Kongruenzprädikates vorgeschlagen, die Schwierigkeiten im Verhältnis von Intension und Extension dieses Terms beseitigen soll. Bei der Konfrontation (...) von Folgerungen aus der Konventionalitätsthese mit der dynamischen Raumtheorie, wie sie im Anschluß an Clifford von J. A. Wheeler entwickelt wurde, treten Unvereinbarkeiten auf, die in der Gegensätzlichkeit von absoluter und relationaler Raumauffassung gründen. (shrink)
