Havstad and Smith (2019) argue that Lakatos’ “methodology of scientific research programs” (MSRP) is a promising philosophical framework for explaining the perceived empirical success of the hypothesis that birds are maniraptoran theropod dinosaurs, and the perceived empirical failures or stagnation of alternatives to that hypothesis. These conclusions are rejected: Havstad and Smith’s account of the alternative “research programs” inadequately characterizes criticism of the hypothesis that birds are maniraptoran theropods and they neither offer sufficient modifications to MSRP to correct its known (...) difficulties in deriving logically or empirically satisfactory criteria for the assessment and preferential selection of “research programs” from historiographical data, nor proposals to mitigate its tendency to promote confirmation bias and dogmatism. Independent flight loss, an important problem in systematic ornithology with implications for the origin of birds, provides a supplementary demonstration of how the application of MSRP in the present context would tend systematically to mislead investigations of the evolutionary history of birds by promoting an uncritical perspective. Given these difficulties, MSRP is an unacceptable philosophical framework for evaluating alternative hypotheses for the origin of birds. (shrink)

Entre los estudios críticos que existen en torno a la obra de Paul Feyerabend predominan aquellos que subrayan una discontinuidad radical entre la versión temprana y tardía de su pensamiento. Todo ello contribuye a que dispongamos de una visión fragmentada e incompleta de un pensador que evoluciono hasta el 1994, año de su fallecimiento. Nuestro propósito es ofrecer una explicación de su itinerario intelectual de tal modo que quedé patente su continuidad en la clave de sus críticas contra los falsos (...) absolutos erigidos por el positivismo lógico y el racionalismo científico. Mostraremos las diversas cuestiones que Feyerabend aborda en las distintas épocas de su vida pero, al mismo tiempo, subrayaremos la unidad o coherencia lógica que existe en su revisión crítica de la racionalidad científica. Nos preocuparemos por entender las razones por las cuales nuestro filósofo de la ciencia va trasladando sus distintos focos de discusión o crítica. A common element in studies of Paul Karl Feyerabend is the distinction between five periods in his work. John Preston sees a radical discontinuity between the early and late versions of Feyerabend’s thought. All of this contributes our having a fragmented and incomplete view of a thinker who continued to evolve until 1994, the year of his death. We aim to provide an explanation of his intellectual journey that shows the evident continuity and unity of his thought. We will discuss the various issues he addressed in the different periods of his life, but at the same time we will emphasize the unity or logical coherence among them. Our aim is to understand the reasons why the philosopher of science changed his distinct foci of discussion and criticism. (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)
