Nagel’s official model of theory-reduction and the way it is represented in the literature are shown to be incompatible with the careful remarks on the notion of reduction Nagel gave while developing his model. Based on these remarks, an alternative model is outlined which does not face some of the problems the official model faces. Taking the context in which Nagel developed his model into account, it is shown that the way Nagel shaped his model and, thus, its well-known deficiencies, (...) are best conceived of as a mere by-product of his philosophical background.

The aim of this essay is a criticism of reductionism ? both in its ?static? interpretation (usually referred to as the layer model or level?picture of science) and in its ?dynamic? interpretation (as a theory of the growth of scientific knowledge), with emphasis on the latter ? from the point of view of Popperian fallibilism and Feyerabendian pluralism, but without being committed to the idiosyncrasies of these standpoints. In both aspects of criticism, the rejection is based on the proposal of (...) a global alternative. Hummell and Opp's research programme for the reduction of sociology to psychology is used as a starting?point and taken as the primary object of criticism. Following the introductory Section I, Section II analyses the three crucial notions of Hummell and Opp's research programme ? their explications of the notions of ?sociology?, ?psychology? and the concept of reduction itself ? and criticizes the authors? deficient ?logic of reduction?. Although the ?local? shortcomings of our authors? ?logic of reduction? do not affect reductionism as such, i.e. logically sound versions of reductionism as devised by Kemeny, Nagel, Oppenheim, Putnam, Woodger et al., it is argued that the logical soundness of sophisticated reductionism cannot compensate for its additional epistemological and methodological deficiencies. Section III analyses the ?dynamic? interpretation of reductionism as a particular developmental pattern of scientific growth. It is argued that even reductionism at its best can produce only cumulative progress, thus ?a priori? excluding scientific revolutions which are inevitably counter?inductive as well as counter?reductive. Section IV discusses the philosophical background of modern reductionism, and examines the effects both of reductionism and of anti?reductionistic pluralism on the autonomy of scientific fields. It is argued that pluralistic anti?reductionism undermines spurious claims for autonomy much more effectively than reductionism. As a ?local? improvement of the reductionistic research programme, the replacement of the predominant one?way reductionism by a less restrictive many?way reductionism is proposed. It is argued that the appropriate treatment for an allegedly backward science (say sociology) is not its reduction to an allegedly more advanced science (say psychology) but its non?reductive replacement by new theories (of the same or of another field) that do not incorporate the older ones. As a ?global? alternative to the reduction of sociology to psychology, the frontier?crossing direct application of psychological theories to sociological phenomena is proposed. A plea is made for a pluralistic science without reduction, based on intra? and interscientific criticism as the proper method for the advancement of knowledge. (shrink)

The relation between religious and scientific explanations of events and states of affairs has been the subject of much debate. For example, are the statements ‘John's life was saved by surgery’ ‘John's life was saved in answer to prayer’ in competition with each other and, if so, in what way? They do not seem to be rival causal explanations, nor are they straightforwardly contradictory. Yet each seems to cast doubt on the other, or at least to make it to some (...) extent redundant.

Intensely discussed in the philosophy of science in the 20th and 21st centuries, the themes of realism and anti-realism pervade Feyerabend’s work. However, discerning the author’s position on these subjects poses a problem for scholars. One sign of this is that they attribute to Feyerabend the adherence to (or the rejection of) different conceptions of realism and anti-realism. Despite the divergences, however, scholars approach the topic in a similar way, detecting elements of Feyerabend’s realist and anti-realist positions that are incompatible (...) with each other and that follow one another in the course of his work. Although such studies are of great value, we propose to explore another approach, which also seems pertinent. Examining Feyerabend’s writings, we seek to discern conditions that make it possible for the author to assume, without contradiction, realist and anti-realist positions. Finally, we seek to infer from Feyerabend’s conception of science features of the realism prescribed by the author as well as features of the realism proscribed by him. (shrink)

1. Introduction. Professor Nagel's account of the “cognitive status” of scientific theories has been attacked by P. K. Feyerabend [5] and M. B. Hesse [8] in terms of his alledgedly misguided distinction between experimental laws and theories. The difficulty lies, these critics agree, in Nagel's attempt to find a stable basis for scientific theories in an observational basis of experimental laws. Both Feyerabend and Hesse note the vacillation in Nagel's account of the stability of the meaning of experimental terms and (...) in his discussion of the status of observational as opposed to theoretical terms. They find Nagel too “positivistic” and see as a first step toward a more adequate account of scientific theories the abandonment of the theoretical-observational dichotomy as having more than a pragmatic significance. Nagel's discussion of the theoretical-observational dichotomy is, I agree, inadequate in certain respects. I shall, however, suggest a quite different remedy from those of Feyerabend and Hesse, one that depends neither on a phenomenalistic reduction of theoretical entities nor on a blurring of the theoretical-observational dichotomy.

El caso Galileo significó para Feyerabend la oportunidad de mostrar metodológica e históricamente las paradojas y limitaciones de una noción positivista de ciencia. A través de este hecho paradigmático de la ciencia moderna el vienés demuestra las contradicciones que suponen los distintos intentos del neo-positivismo lógico por establecer un criterio de demarcación que defina qué es la ciencia. Da cuenta de cómo aquellos elementos frente a los cuales el positivismo lógico procura delimitar una definición negativa de ciencia, constituyen paradojalmente el (...) seno del quehacer científico del físico. Ahora bien, esto no implica –tal como han señalado un número considerable de críticos– que Feyerabend sostenga una visión anárquica, irracionalista o relativista respecto a la ciencia. Por el contrario, en un sentido positivo se puede decir que el caso emblemático de Galileo no sólo le ofreció a Feyerabend la oportunidad de formular una argumentación negativa y escéptica respecto a aquella noción de ciencia sino que, al mismo tiempo, representó para él una ocasión para repensar la ciencia desde una perspectiva o una racionalidad científica más amplia.
