The paper discusses some aspects of the relationship between Feyerabend and Kuhn. First, some biographical remarks concerning their connections are made. Second, four characteristics of Feyerabend and Kuhn's concept of incommensurability are discussed. Third, Feyerabend's general criticism of Kuhn's Structure of Scientific Revolutions is reconstructed. Forth and more specifically, Feyerabend's criticism of Kuhn's evaluation of normal science is critically investigated. Finally, Feyerabend's re-evaluation of Kuhn's philosophy towards the end of his life is presented.

Paul Feyerabend argued that theories can be faced with experimental anomalies whose refuting character can only be recognized by developing alternatives to the theory. The alternate theory must explain the experimental results without contrivance and it must also be supported by independent evidence. I show that the situation described by Feyerabend arises again and again in experiments or observations that test the postulates in the standard cosmological model relating to dark matter. The alternate theory is Milgrom’s modified dynamics. I discuss (...) three examples: the failure to detect dark-matter particles in laboratory experiments; the lack of evidence for dark-matter sub-haloes and the dwarf galaxies that are postulated to inhabit them; and the failure to confirm the predicted orbital decay of Milky Way satellite galaxies and other systems due to dynamical friction against the dark matter. In each case, Feyerabend’s criterion directs us to interpret the experimental or observational results as an indirect refutation of the standard cosmological model in favor of Milgrom’s theory.

From the 1970s onwards, Feyerabend argues against the freedom of science. This will seem strange to some, as his epistemological anarchism is often taken to suggest that scientists should be free of even the most basic and obvious norms of science. His argument against the freedom of science is heavily influenced by his case study of the interference of Chinese communists in mainland China during the 1950s wherein the government forced local universities to continue researching traditional Chinese medicine rather than (...) Western medicine. Feyerabend claims this move was justifiable and, eventually, vindicated by the resulting research which was beneficial for locals and the West at large. The purpose of this paper is to provide a comprehensive overview and analysis on Feyerabend’s views on the freedom of science and his social commentary on US science funding policy that follows therefrom. This proves to be exceedingly difficult because Feyerabend’s writings on the subject are filled with gaps, unnoticed tensions, and cognitive dissonance. Still, I think Feyerabend’s scattered insights and the contradictions that emerge lead to an interesting microcosm of the issues contained in the freedom of science debate. (shrink)

La inconmensurabilidad ha ocasionado innumerables controversias y debates. En estos parece ser unánime la interpretación de tal doctrina como una objeción contra la objetividad, el realismo y el progreso científico. Ahora bien, este marco hermenéutico es estrecho para poder comprender la intencionalidad de Paul Feyerabend al formular su doctrina de la inconmensurabilidad. Pues éste no pretendió cuestionar nunca a dichas nociones en cuanto tales sino únicamente mostrar cuán vano resulta ser el intento del neo-positivismo y del racionalismo popperiano por definirlas. (...) En un sentido positivo sostenemos que la inconmensurabilidad en Paul Feyerabend impide o evita retomar, a la hora de definir aquellas nociones, las dialécticas propias del positivismo lógico o del racionalismo crítico. Nuestra intención en este trabajo es exponer su tesis de la inconmensurabilidad como un cuestionamiento a un modo particular de concebir la racionalidad científica y a sus consecuentes nociones de objetividad, progreso y realismo científico.

In this paper, we demonstrate how a systematic taxonomy of stances can help elucidate two classic debates of the historical turn—the Lakatos–Feyerabend debate concerning theory rejection and the Feyerabend–Kuhn debate about pluralism during normal science. We contend that Kuhn, Feyerabend, and Lakatos were often talking at cross-purposes due to the lack of an agreed upon taxonomy of stances. Specifically, we provide three distinct stances that scientists take towards theories: acceptance of a theory as the best available description of its domain, (...) use of a theory in practical applications, and pursuit (elaboration) of a theory. We argue that in the Lakatos–Feyerabend debate, Lakatos was concerned with acceptance whereas Feyerabend was mainly concerned with pursuit. Additionally, we show how Feyerabend and Kuhn’s debate on the role of pluralism/monism in normal science involved a crucial conflation of all three stances. Finally, we outline a few general lessons concerning the process of scientific change. (shrink)

This paper explores Paul Feyerabend's (1924-1994) skeptical arguments for "anarchism" in his early writings between 1960 to 1975. Feyerabend's position is encapsulated by his well-known suggestion that the only principle for scientific method that can be defended under all circumstances is: "anything goes." I present Feyerabend's anarchism as a recommendation for pluralism that assumes a realist view of scientific theories. The aims of this paper are threefold: (1) to present a defensible view of Feyerabend's anarchism and its motivations, (2) to (...) articulate the minimal form of realism that such a view presupposes, and (3) to consider the implications and limitations of such a perspective in contemporary philosophy of science.

In this paper I argue against the traditional viewthat in discovery processes there is no place forrational decisions. First I argue that some historicalprocesses in which an empirical law was developed,were rational. Second, I identify some of themethodological rules that we can follow in order to berational when constructing an empirical law. Finally,I argue that people who deny that scientific discoverycan be rational do not understand the nature ofmethodological rules.

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.

John Preston has contended that Paul Feyerabend retreated from his earlier commitment to realism and consciously embraced a ‘voluntarist’, social constructionist, idealism. Though there seems to be unmistakable subjective idealist statements in some of Feyerabend's writings, it will be argued that Feyerabend's idealistic period was short-lived, and that he returned to a form of realism in his later writings. Specifically, Feyerabend's distinction between theoretical/abstract and empirical/historical traditions of thought, when understood with Feyerabend's re evaluation of Bohr's philosophy of quantum physics (...) in mind, is most aptly interpreted as aprocess realist position. Preston, in interpreting Feyerabend as a voluntarist, social constructionist, subjective idealist, fails to distinguish the ever-present rhetorical and provocative statements of Feyerabend's from the core arguments being presented.

Michael Polanyi argues in Personal Knowledge (1958) that conceptual frameworks involved in major scientific controversies are separated by a `logical gap'. Such frameworks, according to Polanyi (1958: 151), are logically disconnected: their protagonists think differently, use different languages and occupy different worlds. Relinquishing one framework and adopting another, Polanyi's scientist undergoes a `conversion' to a new `faith'. Polanyi, in other words, presaged Kuhn and Feyerabend's concept of incommensurability. To what influences was Polanyi subject as he developed his concept of the (...) logical gap? The answer, as unfolded in this article, is twofold: Evans-Pritchard's Witchcraft, Oracles and Magic among the Azande and the Confessions of St Augustine. (shrink)

Los críticos que han interpretado el pensamiento de Feyerabend como un relativismo radical no hacen justicia a su intencionalidad, y se muestran incapaces de comprender la unidad de su obra, en particular, su abandono posterior de los ideales relativistas. Se busca distinguir las diversas posiciones de Feyerabend frente al relativismo y exponer su reducción al absurdo de las nociones de la ciencia propias del positivismo lógico y del racionalismo crítico. Así mismo, se plantea cómo Feyerabend, ante la ausencia de un (...) criterio para discernir la tarea científica, postula un relativismo, pero, al final de su vida, busca elaborar una metafísica de la abundancia que supere las coordenadas de aquel. Critics who have interpreted Feyerabend's work as radical relativism do not do justice to his intentions and do not understand the unity of his work, in particular, his later abandonment of relativist ideals. This article seeks to distinguish the diverse Feyerabend's positions regarding relativism and exposes his reduction to absurdity of the ideas of science belonging to logical positivism and critical rationalism. It also addresses the way in which Feyerabend postulated relativism when faced with the absence of criteria to discern the scientific task. It argues, however, that at the end of his life Feyerabend seeked to construct a metaphysics of abundance in order to surpass relativism. (shrink)

El pensamiento de Feyerabend ha sido objeto de múltiples y divergentes interpretaciones. Pero entre ellas parece ser unánime la inscripción de su obra dentro de las coordenadas de una epistemología posmoderna. Estas lecturas podrían encontrar sustento en su anarquismo epistemológico el cual constituye en sí mismo una reducción al absurdo de los intentos del positivismo lógico y del racionalismo crítico por definir axiomática o metodológicamente la ciencia. En este sentido, su obra puede ser entendida, en parte, como una argumentación negativa (...) y escéptica respecto a aquellas nociones de ciencia. No obstante, esta hermenéutica no deja de ofrecer una visión fragmentaria y parcial de su pensamiento y, particularmente, de su obra tardía. Nuestro propósito es reconstruir el pensamiento que formula en sus últimos años, con el fin de mostrar que éste no cumple las características posmodernas que habitualmente se le adjudican. Y, particularmente, determinar el sentido por el cual sería legítimo caracterizar su obra como posmoderna. (shrink)

Feyerabend a lo largo de su obra varía y reforma el abordaje de la cuestión acerca de la relación entre ciencia y metafísica. Sus especialistas conocen con frecuencia cómo plantea dicha cuestión entre los 60 y finales de los 70, cuando está preocupado por resolver el problema de la inconmensurabilidad. Pero desconocen su posterior evolución. El objetivo de esta comunicación es presentar, a través de las confrontaciones que Feyerabend mantiene con sus interlocutores, las distintas connotaciones y roles que adquiere la (...) metafísica respecto a la ciencia. Creemos que de este modo intentaremos hacer justicia a un pensador que no sido aún suficientemente comprendido y valorado. (shrink)

A fines de los 50 y a lo largo de los años 60 Feyerabend formula su doctrina de la proliferación teórica. Con ella busca inicialmente destacar la presencia positiva de la metafísica en el proceso de explicación teórica. Concretamente, pretende dar cuenta de la impotencia de toda teoría científica de explicar realísticamente el mundo si no estuviera informada por supuestos que sus interlocutores juzgan como a-científicos o pre-científicos. Ahora bien, para poder precisar el papel que juega la metafísica en el (...) proceso de explicación teórica es preciso dilucidar qué entiende Feyerabend por realismo. Entre los especialistas existe una discusión acerca de si este defiende un realismo científico o un antirrealismo. Con el propósito de poder comprender en qué sentido Feyerabend sostiene que la metafísica provee vías de acceso para explicar el mundo, procuraremos demostrar la naturaleza normativa de su realismo. At the end of the 50s and throughout the 60s, Feyerabend formulated his doctrine of theoretical proliferation. With this doctrine, he sought to emphasize the positive presence of metaphysics in the process of theoretical explanation. In particular, he claims to account for the impotence of any scientific theory for realistically explaining the world if it was not informed by some assumptions that his partners judge as non-scientific or pre-scientific. However, in order to specify the role of metaphysics in the process of theoretical explanation it is necessary to clarify what Feyerabend understands for realism. Among specialists there is a discussion about whether he defended a scientific realism or an anti-realism. In order to be able to understand in what sense Feyerabend holds that metaphysics provides access ways to explain the world, we will try to demonstrate the normative nature of his realism. (shrink)
