This volume is devoted to a reappraisal of the philosophy of Paul Feyerabend. It has four aims. The first is to reassess his already well-known work from the 1960s and 1970s in light of contemporary developments in the history and philosophy of science. The second is to explore themes in his neglected later work, including recently published and previously unavailable writings. The third is to assess the contributions that Feyerabend can make to contemporary debate, on topics such as perspectivism, realism, (...) and political philosophy of science. The fourth and final aim is to reconsider Feyerabend's place within the history of philosophy of science in the light of new scholarship. (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)

This is a partly provocative essay edited as a humanitarian study in philosophy of science and social philosophy. The starting point is Isaac Asimov’s famous sci-fi novella “Profession” (1957) to be “back” extrapolated to today’s relation between Thomas Kuhn’s “normal science” and “scientific revolutions” (1962). The latter should be accomplished by Asimov’s main personage George Platen’s ilk (called “feeble minded” in the novella) versus the “burned minded” professionals able only to “normal science”. Francis Fukuyama’s “end of history” in post-Hegelian manner (...) is now interpreted to an analogically supposed “end of scientific history” without “scientific revolutions” any more. The relevant dystopia of the prolonged or even “eternal” period of normal science is justified to the contemporary institution of science due to mechanisms such as “peer-review”, “impact-factor rating”, the projects’ competition for funding, etc. Positive feedbacks forcing all scientists needing careers to be more and more orthodox are demonstrated therefore establishing for that dystopia to be the real state of contemporary science. Two counterfactual case studies based correspondingly on Feyerabend’s “Against method” (1975) if Galilei should make his discoveries today and Sokal’s hoax (1996) if he suggested a scientific masterpiece to be really rejected by journals are discussed. Still one case study considering the abundance of Kelvin’s “clouds” on the horizon of today’s physics (dark matter, dark energy, entanglement, quantum gravitation, phenomena refuting the Big Bang, etc.) serves to verify the aforementioned conjecture that science has already entered that dystopia of eternal normal science. The conception of “ontomathematics” implying “creation ex nihilo” being scandalous for the dominating paradigm is sketched as an eventual revolutionary way out. An imaginary and utopic “happy end” reinterpreting the analogical “happy end” of Asimov’s “Profession” finishes the essay “instead of conclusion” relying on the Internet and AI in an increasingly “fluid” and anti-hierarchical society.

Bohr’s work in quantum mechanics posed a challenge to philosophers of science, who struggled with the question of whether and to what degree his theories and methods could be considered rational. This paper focuses on Popper, Feyerabend, Lakatos and Kuhn, all of whom recognized some irrational, dogmatic, paradoxical or even inconsistent features in Bohr’s work. Popper, Feyerabend, and Lakatos expressed strong criticism of Bohr’s approach to quantum physics, while Kuhn argued that such criticism was unlikely to be fruitful: progress in (...) science is generally not made through philosophical reflection. Feyerabend’s criticism of Bohr gradually weakened, as he gained a more detailed understanding of the development of Bohr’s views on quantum mechanics, and this went together with an increasingly critical view of normative philosophy of science and was instrumental to his conversion to ‘anarchism’. This paper aims to show that quantum mechanics played a central role in their debates and disagreements on the rationality of science and the possibility of a normative philosophy of science.

The alleged emergence of a ‘post-truth’ regime links the rise of new forms of social media and the reemergence of political populism. Post-truth has theoretical roots in the interdisciplinary field of Science and Technology Studies, with sociologists of science arguing that both true and false claims should be explained by the same kinds of social causes. Most STS theorists have sought to deflect blame for post-truth, while at the same time enacting a normative turn, looking to deconstruct truth claims and (...) subject expertise to criticism. Steve Fuller has developed a positive case for post-truth in science, arguing that post-truth democratizes science. I criticize this argument and suggest an alternative approach that draws on the prehistory of the field in the 1930s and 1940s, when philosophers and sociologists sought to define the social conditions necessary for reliable knowledge production that might stem mass media irrationalism.

In the paper I consider how empirical material, from either history or sociology, features in Kuhn’s account of science in The Structure of Scientific Revolutions and argue that the study of scientific practice did not offer him data to be used as evidence for defending hypotheses but rather cultivated a sensitivity for detail and difference which helped him undermine an idealized conception of science. Recent attempts in the science studies literature, appealing to Wittgenstein’s philosophy, have aimed at reducing philosophy to (...) multifaceted empirical research in relation to science. I discuss how this turn which is at odds with Wittgenstein’s philosophy, cannot be a continuation of Kuhn’s project which bears similarities to Wittgenstein’s. (shrink)

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.

: In this essay I argue that Kuhn's account of science, as it was articulated in The Structure of Scientific Revolutions, was mainly defended on philosophical rather than historical grounds. I thus lend support to Kuhn's later claim that his model can be derived from first principles. I propose a transcendental reading of his work and I suggest that Kuhn uses historical examples as anti-essentialist Wittgensteinian "reminders" that expose a variegated landscape in the development of science.

The goal of this dissertation is to reconstruct, critically evaluate, and apply the pluralism of Paul Feyerabend. I conclude by suggesting future points of contact between Feyerabend’s pluralism and topics of interest in contemporary philosophy of science. I begin, in Chapter 1, by reconstructing Feyerabend’s critical philosophy. I show how his published works from 1948 until 1970 show a remarkably consistent argumentative strategy which becomes more refined and general as Feyerabend’s thought matures. Specifically, I argue that Feyerabend develops a persuasive (...) case against rationalism, or the thesis that there exist normative and exclusive rules of scientific rationality. In Chapter 2, I reconstruct Feyerabend’s pluralism and detail its relationship to his humanitarianism and epistemological anarchism. I understand Feyerabend’s pluralism as the combination of the principles of proliferation and tenacity. I show the evolution and justification of these principles from Feyerabend’s early papers until the late 1970s. In Chapter 3, I defend Feyerabend’s pluralism from its most prominent criticisms. I then clarify that Feyerabend’s pluralism amounts to a conception of the logic of theory pursuit and modify his view using insights from C.S. Peirce, Pierre Duhem, and Michael Polanyi. From Peirce, I show how economic, sociological, and value-laden features of theory pursuit may be used to constrain proliferation and tenacity. From Duhem and Polanyi, I try to show the proper role of tacit knowledge within a Feyerabendian framework. Finally, I show what implications Feyerabend’s pluralism has for models of distributing funds within scientific communities. I contend that it provides a more promising model that the ‘well-ordered science’ proposal advanced by numerous philosophers and social scientists. Specifically, I aim to understand what taking Feyerabend’s pluralism seriously entails for principles of balancing funding allocation decisions and the role of peer-review in evaluating the potential success of research proposals. I conclude by suggesting future lines of research for further analyzing and applying Feyerabend’s pluralism. (shrink)

To anyone vaguely aware of Feyerabend, the title of this paper would appear as an oxymoron. For Feyerabend, it is often thought, science is an anarchic practice with no discernible structure. Against this trend, I elaborate the groundwork that Feyerabend has provided for the beginnings of an approach to organizing scientific research. Specifically, I argue that Feyerabend’s pluralism, once suitably modified, provides a plausible account of how to organize science. These modifications come from C.S. Peirce’s account of the economics of (...) theory pursuit, which has since been corroborated by empirical findings in the social sciences. I go on to contrast this approach with the conception of a ‘well-ordered science’ as outlined by Kitcher (Science, truth, and democracy, Oxford University Press, New York, 2001), Cartwright (Philos Sci 73(5):981–990, 2006), which rests on the assumption that we can predict the content of future research. I show how Feyerabend has already given us reasons to think that this model is much more limited than it is usually understood. I conclude by showing how models of resource allocation, specifically those of Kitcher (J Philos 87:5–22, 1990), Strevens (J Philos 100(2):55–79, 2003) and Weisberg and Muldoon (Philos Sci 76(2):225–252, 2009), unwittingly make use of this problematic assumption. I conclude by outlining a proposed model of resource allocation where funding is determined by lottery and briefly examining the extent to which it is compatible with the position defended in this paper.

Paul Feyerabend once made a remark to the effect that his pragmatic theory of observation can be traced back to proposals put forward by leading Logical Empiricists during the height of the protocol sentence debate. In this paper I want to vindicate the systematic side of Feyerabend’s remark and show that a pragmatic theory of observation can in fact be found in Rudolf Carnap’s writings of 1932. I first proceed to dispel a misunderstanding concerning the term “pragmatic” raised by Thomas (...) Oberdan. Following Morris’ and Carnap’s documented usage, I show that the intended meaning of “pragmatic” refers to a specific semiotic relation between users of a language and their environment describable by empirical means. I reconstruct such a pragmatic theory in terms of a detector model that interprets observation sentences as bodily dispositions indicating physical events in the surroundings of the detector. I then proceed to show how Feyerabend’s later theory of observation picks up central features of Carnap’s account and also shares some of the motivations. I conclude by noting how an empirical theory of observation sentences offers a bootstrapping solution to the “basis problem”. (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.

Steve Fuller has replied to my critique of his endorsement of a post-truth epistemology. I trace the divergence in our approach to social epistemology by examining our distinct responses to the principle of symmetry in the sociology of scientific knowledge. Fuller has extended the concept of symmetry and challenged the field to embrace a post-truth condition that flattens the difference between experts and the public. By contrast, I have criticized the concept of symmetry for policing the field to rule ideology (...) critique out of court. I argue that a focus on post-truth populism obscures the role of counter-elites and ideologies that restrict political choice. A better way to promote democracy would be to support minority positions within science that promise to open up suppressed political possibilities and to seek the coordinated use of different disciplines to address significant public problems.

When David Bohm published his alternative theory of quantum mechanics in 1952, it was not received well; a recurring criticism was that it formed a reactionary attempt to return to classical physics. In response, Bohm emphasized the progressiveness of his approach, and even turned the accusation of classicality around by arguing that he wanted to move beyond classical elements still inherent in orthodox quantum mechanics. In later years, he moved more and more towards speculative and mystical directions. This paper aims (...) to explain this discrepancy between the ways in which Bohm’s work on quantum mechanics has been received and the way in which Bohm himself presented it. I reject the idea that Bohm’s early work can be described as mechanist, determinist, and realist, in contrast to his later writings, and argue that there is in fact a strong continuity between his work on quantum mechanics from the early 1950s and his later, more speculative writings. In particular, I argue that Bohm was never strongly committed to determinism and was a realist in some ways but not in others. A closer look at Bohm’s philosophical commitments highlights the ways in which his theory of quantum mechanics is non-classical and does not offer a way to avoid all ‘quantum weirdness’. (shrink)

The paper contains two yet unknown letters that Feyerabend wrote to Kuhn in 1960 or 1961 on a draft of The Structure of Scientific Revolutions. In these letters, Feyerabend criticises both details of Kuhn's book and its general direction. The letters anticipate many of the arguments that were put forward in the public controversy against Kuhn's position, including some of the (numerous) misunderstandings. Feyerabend's assertions and arguments are very characteristic of his position in the early sixties.

: This paper analyzes the development of Kuhn's metaphilosophical position concerning the proper relationship between the history and the philosophy of science. I reconstruct Kuhn's model of scientific change presented in Structure as having the logical status of a Weberian explanatory theory; the philosophy of science and the history of science were of equal importance in its development and defense. However, Kuhn's metaphilosophical position changed in the 1990s, when he gave primacy to philosophy over the history of science in response (...) to the challenge new sociology of science presented to his views. I analyze Kuhn's seldom discussed 'first principles' and argue that the locution should be understood as marking this metaphilosophical shift. Kuhn's project in his last writings was to develop epistemology and metaphysics capable of withstanding relativism and of selecting cognitive internal historiography as the appropriate historiography for the philosophy of science. I sketch the contours of this project which Kuhn was unable to complete in his lifetime. (shrink)

The present paper aims at highlighting some of the main characteristics of a descriptive contextual approach to philosophy. Descriptive, in the sense that it centers not on the question of what philosophy should be, but on what philosophy is, has been, or may be. And contextual, in the sense that it treats philosophy as human praxis situated in and interacting with certain social and historical settings. In order to develop such an account, we engage closely with Kuhn’s paradigm-centered contextual approach (...) to science and examine, following Rorty, how it could be regarded in connection to philosophy. The paper concludes with a brief discussion of two concrete cases to which such an approach may be applied, the division between analytic and continental philosophy at the level of philosophical traditions, and the case of Wittgenstein’s life and thought at the level of individual philosophers.

This paper examines ‘The Natures of Conceptual Change’, the Notre Dame lectures given by Kuhn in 1980. In particular, I aim to examine the content of these lectures which was not published before. This exegetical task will shed light on the sources of the notion of taxonomy used in these lectures for the first time with the explicit philosophical purposes. It also will shed new light on Kuhn's position regarding the causal theory of reference. Reviewing these archival materials paves the (...) way for intertextual comparisons, as Kuhn included part of these lectures in the texts published later and in the book Plurality of Worlds: an Evolutionary Theory of Scientific Development. In recent years, the publication of Kuhn's archival material and the research on these texts increased in quantity and quality. Faced with this encouraging landscape, a comparative examination of the different unpublished texts is crucial to refining both our research tools on Kuhn's intellectual biography and the philosophical work inspired by his proposal.

Philosophy of the Social Sciences, Volume 52, Issue 5, Page 306-321, September 2022.

Kuhn and Feyerabend have little to say about the thought of Michael Polanyi, and the secondary literature on Polanyi's relation to them is meagre. I argue that Polanyi's view, in Personal knowledge and in other writings, of conceptual frameworks ‘segregated’ by a ‘logical gap’ as giving rise to controversies in science foreshadowed Kuhn and Feyerabend's theme of incommensurability. The similarity between the thinkers is, I suggest, no coincidence.

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)

The ArgumentMost lay users of statistics think in terms of means (averages), variances or the square of the standard deviation, and Gaussians or bell-shaped curves. Such conventions are entrenched by statistical practice, by deep mathematical theorems from probability, and by theorizing in the various natural and social sciences. I am not claiming that the particular conventions (here, the statistics) we adopt are arbitrary. Entrenchment can be rational without its being as well categorical (excluding all other alternatives), even if that entrenchment (...) claims also to provide for categoricity. 1 provide a detailed description of how a science is “normal” and conventionalized. A characteristic feature of this entrenchment of conventions by practice, theorems, and theorizing, is its highly technical form, the canonizing work enabled by apparently formal and esoteric mathematical means.

Incommensurability of scientific theories, as conceived by Thomas Kuhnand Paul Feyerabend, is thought to be a major or even insurmountable obstacletothe empirical comparison of these theories. I examine this problem in light ofaconcrete case from the history of experimental biology, namely the oxidativephosphorylation controversy in biochemistry (ca. 1961-1977). After a briefhistorical exposition, I show that the two main competing theories which werethe subject of the ox-phos controversy instantiate some of the characteristicfeatures of incommensurable theories, namely translation failure,non-corresponding predictions, and different (...) claims about what kinds ofentitiesexist in the world. By examining how the controversy was eventually resolved, Ithen show that at least this pair of incommensurable theories couldneverthelessbe empirically compared. (shrink)

In this essay I argue that Kuhn's account of science, as it was articulated in The Structure of Scientific Revolutions, was mainly defended on philosophical rather than historical grounds. I thus lend support to Kuhn's later claim that his model can be derived from first principles.
