The work of Thomas Kuhn has been very influential in Anglo-American philosophy of science and it is claimed that it has initiated the historical turn. Although this might be the case for English speaking countries, in France an historical approach has always been the rule. This article aims to investigate the similarities and differences between Kuhn and French philosophy of science or ‘French epistemology’. The first part will argue that he is influenced by French epistemologists, but by lesser known authors (...) than often thought. The second part focuses on the reactions of French epistemologists on Kuhn’s work, which were often very critical. It is argued that behind some superficial similarities there are deep disagreements between Kuhn and French epistemology. This is finally shown by a brief comparison with the reaction of more recent French philosophers of science, who distance themselves from French epistemology and are more positive about Kuhn. Based on these diverse appreciations of Kuhn, a typology of the different positions within the philosophy of science is suggested. (shrink)

The ‘triumph of the anti-phlogistians’ is a familiar story to the historians and philosophers of science who characterize the Chemical Revolution as a broad conceptual shift. The apparent “incommensurability” of the paradigms across the revolutionary divide has caused much anxiety. Chemists could identify phlogiston and oxygen, however, only with different sets of instrumental practices, theoretical schemes, and philosophical commitments. In addition, the substantive counterpart to phlogiston in the new chemistry was not oxygen, but caloric. By focusing on the changing visions (...) of chemical body across the revolutionary divide with a more sensitive probe into the historical actors’ material manipulations and linguistic usage, we can historicize their laboratory realities and philosophical agenda. An archeology of chemical bodies that configures the fragile stability of the material worlds chemists created in succession promises a philosophical horizon that would recognize our hybrid (natural–artificial) environment as an evolving investigative object of science.

In inter-war France, history of philosophy was a very important academic discipline, but nevertheless its practitioners thought it necessary to defend its identity, which was threatened by its vicinity to many other disciplines, and especially by the emergent social sciences and history of science. I shall focus on two particular issues that divided traditional historians of philosophy from historians of science, ethnologists and sociologists, and that became crucial in the definition of the identity of their disciplines: the conception of history (...) and the interpretation of texts. By analysing representative discussions and positions, I shall show that traditional historians of philosophy needed to reassert their own approach to history, which, borrowing the term from Bergson, I define as ‘snapshot’. This approach is focused on a particular idea or text rather than a narrative. I shall also show that history of philosophy, in its traditional form, would have been undermined both intellectually and institutionally by the opposite ‘narrative’ approach of history of science and of the social sciences. Social scientists openly attacked history of philosophy’s methods and, in the eyes of traditional philosophers, its existence as an academic discipline. The same opposition is to be found in evaluation of past texts, which for traditional historians of philosophy were to be read as timeless documents, while for historians of science, ethnologists and sociologists were to be considered as documents exhibiting a particular mentality. However, between these alternatives there were intermediate positions. I shall in particular consider that of Léon Brunschvicg: he embraced a narrative approach and considered texts as documents of different ways of thinking, but at the same time carried on employing philosophical methods and defending the institutional position of philosophy. I shall argue that this was possible partly because of the considerable amount of power he enjoyed at the Sorbonne. (shrink)

During the second half of the twentieth century, historians of science have shown a considerable interest in ‘presentism’, a term first applied to the kind of history of science in which past knowledge is judged to celebrate and legitimize modern science. Taking Herbert Butterfield’s The Whig interpretation of history as a point of reference, ‘presentism’ has been usually associated with ‘Whig history’ or ‘Whiggish history’. Nevertheless, Butterfield’s essay is one of many approaches to this question. In this article, I examine (...) Hélène Metzger’s La méthode philosophique dans l’histoire des sciences, a major theoretical contribution of ‘presentism’. I argue that the papers she published in the 1930s are among the most important critical reflections on ‘presentism’ written by a historian of science before 1950. Through this examination, I demonstrate that Hélène Metzger‘s ideas can provide historians of science with a useful set of tools to reflect upon ‘presentism’, beyond the narrow definition of the latter as ‘Whig history’.

At first glance twentieth-century philosophy of science seems virtually to ignore chemistry. However this paper argues that a focus on chemistry helped shape the French philosophical reflections about the aims and foundations of scientific methods. Despite patent philosophical disagreements between Duhem, Meyerson, Metzger and Bachelard it is possible to identify the continuity of a tradition that is rooted in their common interest for chemistry. Two distinctive features of the French tradition originated in the attention to what was going on in (...) chemistry.French philosophers of science, in stark contrast with analytic philosophers, considered history of science as the necessary basis for understanding how the human intellect or the scientific spirit tries to grasp the world. This constant reference to historical data was prompted by a fierce controversy about the chemical revolution, which brought the issue of the nature of scientific changes centre stage.A second striking—albeit largely unnoticed—feature of the French tradition is that matter theories are a favourite subject with which to characterize the ways of science. Duhem, Meyerson, Metzger and Bachelard developed most of their views about the methods and aims of science through a discussion of matter theories. Just as the concern with history was prompted by a controversy between chemists, the focus on matter was triggered by a scientific controversy about atomism in the late nineteenth-century.Keywords: France; Epistemology; Chemistry; Revolution; Atomism; Realism.

In this contribution, I comment on Raffaella Campaner’s defense of explanatory pluralism in psychiatry (in this volume). In her paper, Campaner focuses primarily on explanatory pluralism in contrast to explanatory reductionism. Furthermore, she distinguishes between pluralists who consider pluralism to be a temporary state on the one hand and pluralists who consider it to be a persisting state on the other hand. I suggest that it would be helpful to distinguish more than those two versions of pluralism – different understandings (...) of explanatory pluralism both within philosophy of science and psychiatry – namely moderate/temporary pluralism, anything goes pluralism, isolationist pluralism, integrative pluralism and interactive pluralism. Next, I discuss the pros and cons of these different understandings of explanatory pluralism. Finally, I raise the question of how to implement or operationalize explanatory pluralism in scientific practice; how to structure the “genuine dialogue” or shape “the pluralistic attitude” Campaner is referring to. As tentative answers, I explore a question-based framework for explanatory pluralism as well as social-epistemological procedures for interaction among competing approaches and explanations.

Scientific classification has long been recognized as involving a specific style of reasoning and doing research, and as occasionally affecting the development of scientific theories. However, the role played by classificatory activities in generating theories has not been closely investigated within the philosophy of science. I argue that classificatory systems can themselves become a form of theory, which I call classificatory theory, when they come to formalize and express the scientific significance of the elements being classified. This is particularly evident (...) in some of the classification practices used in contemporary experimental biology, such as bio-ontologies used to classify genomic data and typologies used to classify “normal” stages of development in developmental biology. In this paper, I explore some characteristics of classificatory theories and ways in which they differ from other types of scientific theories and other components of scientific epistemology, such as models and background assumptions.

The pheneticist philosophy holds that biological taxa are clusters of entities united by a form of all-things-considered resemblance. This view of taxonomy has come in for almost universal criticism from philosophers, and has received little praise from biologists, over the past 30 years or so. This article defends a modest pheneticism, understood as part of a pluralist view of taxonomy. First, phenetic approaches to taxonomy are alive and well in biological practice, especially in the areas of microbiology and botany. Second, (...) the pheneticist notion of overall similarity is defensible, and is implicitly endorsed even by those (such as Quine) usually implicated in attacks on similarity. Third, there are limited biological domains within which pheneticism’s conception of species as kinds (rather than heterogeneous individuals) remains applicable. (shrink)

In this article I assess Georges Canguilhem's historical epistemology with both theoretical and historical questions in mind. From a theoretical point of view, I am concerned with the relation between history and philosophy, and in particular with the philosophical assumptions and external norms that are involved in history writing. Moreover, I am concerned with the role that history can play in the understanding and evaluation of philosophical concepts. From a historical point of view, I regard historical epistemology, as developed by (...) Gaston Bachelard and Georges Canguilhem, as a conception and practice which came out of the project, elaborated in France from the 1920s to the 1940s, of combining history of science and philosophy. I analyse in particular Canguilhem's epistemology in his theory and practice of history of science. What he called 'normative history' is the focus of my analysis. I evaluate the question of the nature and provenience of the norm employed in normative history, and I compare it with the norm as discussed by Canguilhem in Le normal et le pathologique. While I am critical of Canguilhem's treatment of history, I conclude that his philosophical suggestion to analyse the formation of scientific concepts 'from below' represents a useful model for history and philosophy of science, and that it can be very profitably extended to philosophical concepts.

In May 1933 the historian of chemistry Hélène Metzger addressed a letter to the renowned historian and philosopher of science Émile Meyerson, a cri de coeur against Meyerson’s patronizing attitude toward her. This recently discovered letter is published and translated here because it is an exceptional human document reflecting the gender power structure of our discipline in interwar France. At the age of forty‐three, and with five books to her credit, Metzger was still a junior scholar in the exclusively male (...) community of French historians and philosophers of science. We sketch the institutional setting of higher learning in France at the time, noting the limited openings it offered to would‐be femmes savantes, and situate Metzger in this context. We also describe the philosophical differences between Metzger and Meyerson. Though Metzger never managed to obtain a post of her own, in her letter to Meyerson she forcefully lays claim, at least, to a mind of her own. (shrink)

Bachelard regarded the scientific changes that took place in the early twentieth century as the beginning of a new era, not only for science, but also for philosophy. For him, the theory of relativity and quantum mechanics had shown that a new philosophical ontology and a new epistemology were required. I show that the type of philosophy with which he was more closely associated, in particular that of Léon Brunschvicg, offered to him a crucial starting point. Brunschvicg never considered scientific (...) objects as independent of the mind, and as a consequence questions such as the existence of particles independently of the mind, theory or apparatus, were absent from his philosophy, which was rather aimed at analyzing the mind critically, and above all historically. Bachelard accepted the fundamental ideas of Brunschvicg’s philosophy; however, his own reading of contemporary science enabled him to go beyond it, as shown by his emphasis on the social production of knowledge, and by his removal of the distinction between ideas and technologically produced objects of knowledge. For him, modern science teaches philosophy that knowledge is not a phenomenology but rather a ‘phenomenotechnique’. I argue that Bachelard’s view that philosophy ‘should follow science’ stems from moral considerations.Keywords: Gaston Bachelard; Léon Brunschvicg; Phenomenotechnique; Chosisme; Theory of relativity; Quantum mechanics.

This article engages with the philosophical reflections of the French historian of science Hélène Metzger (1886–1944) in order to develop a vocabulary for understanding the rise of non-reductive Continental naturalism in the contemporary humanities. The bibliography of current naturalist approaches in the arts and the human sciences is still in the making, but it is altogether clear that the trend is not scientist or historicist or relativist. This epistemological diagnosis refers us to Metzger, who found herself surrounded with the logical (...) positivism of the Wiener Kreis, on the one hand, and the historicism of her French colleagues, on the other, as well as with the infiltration of the history of science by a chronological empiricism. In this article I will take the most recent book of Vicki Kirby – Quantum Anthropologies: Life at Large from 2011 – as an exemplary case of non-reductive Continental naturalist scholarship in the humanities today and by reading it through the concepts of Metzger, I will demonstrate how this type of research leads to refreshing insights in what constitutes positive humanities knowledge and what is the role of the a priori in the field.
