Stars are conspicuously absent from reflections on natural kinds and scientific classifications, with gold, tiger, jade, and water getting all the philosophical attention. This is too bad for, as this paper will demonstrate, interesting philosophical lessons can be drawn from stellar taxonomy as regards two central, on-going debates about natural kinds, to wit, the monism/pluralism debate and the realism/antirealism debate. I’ll show in particular that stellar kinds will not please the essentialist monist, nor for that matter will it please the (...) pluralist embracing promiscuous realism à la Dupré. (shrink)

L'enjeu de cet article est d'appréhender la dynamique de la théorie de l'ordre au XIXe siècle et de mettre au jour une approche spécifique des mathématiques, des sciences, de la philosophie et de l'art ornemental dans laquelle l'ordre joue un rôle prééminent. Nous reviendrons sur la signification singulière que Poinsot assigne à l'ordre dans les sciences mathématiques, avant de décrire la circulation de ses écrits sur l'ordre au XIXe siècle. Poinsot constitue l'une des principales sources de Cournot qui situe l'ordre (...) et la forme au fondement de son système de connaissances. Enfin, nous nous intéresserons aux écrits de Bourgoin qui développe une combinatoire des ornements, fondée sur les catégories d'ordre et de forme. (shrink)

It is a common opinion that chance events cannot be understood in causal terms. Conversely, according to a causal view of chance, intersections between independent causal chains originate accidental events, called “coincidences.” The present paper takes into proper consideration this causal conception of chance and tries to shed new light on it. More precisely, starting from Hart and Honoré’s view of coincidental events, this paper furnishes a more detailed account on the nature of coincidences, according to which coincidental events are (...) hybrids constituted by ontic components, that is the intersections between independent causal chains, plus epistemic aspects; where by “epistemic” we mean what is related, in some sense, to knowledge: for example, access to information, but also expectations, relevance, significance, that is psychological aspects. In particular, this paper investigates the role of the epistemic aspects in our understanding of what coincidences are. In fact, although the independence between the causal lines involved plays a crucial role in understanding coincidental events, that condition results to be insufficient to give a satisfactory definition of coincidences. The main target of the present work is to show that the epistemic aspects of coincidences are, together with the independence between the intersecting causal chains, a constitutive part of coincidental phenomena. Many examples are offered throughout this paper to enforce this idea. This conception, despite—for example—Antoine Augustine Cournot and Jacques Monod’s view, entails that a pure objectivist view about coincidences is not tenable. (shrink)

Dans un article décisif sur la naissance du calcul des probabilités (1970), Ernest Coumet rappelait la formule de Cournot selon laquelle le retard qui marque la naissance de la théorie du hasard est «un pur effet du hasard». On se propose ici de soumettre ce jugement à l'examen critique non de l'histoire, mais de la pensée même de Cournot; sa philosophie de l'histoire et sa représentation de l'histoire des sciences au XVIIe siècle semblant, tout d'abord, dénoncer par avance un jugement (...) aussi péremptoire. Pour rendre compte de ce qui peut alors apparaître de sa part comme une inconséquence, voire un aveuglement, on forme l'hypothèse que cette affirmation constitue un artefact de sa conception internaliste de l'histoire des sciences et des révolutions scientifiques. En ce sens, larticle constitue une illustration de la nécessité théorique, mais aussi des difficultés de l'histoire des mathématiques. (shrink)

Pierre Duhem can be looked upon as one of the heirs of a tradition of historical and philosophical researches that flourished in the second half of the nineteenth century. This tradition opposed the naïve historiography and epistemology of the positivist school. Beside the positivists of different leanings such as Littré, Laffitte, Wyrouboff, and Berthelot, we find Cournot, Naville, and Tannery, who developed sophisticated histories and philosophies of science focusing on the real scientific practice and its history. They unfolded elements of (...) continuity and discontinuity in the history of science, and enlightened the complex relationship among experimental, mathematical, logical and philosophical components in scientific practice. In Pierre Duhem we find a systematic and vivid interpretation of these meta-theoretical issues, and a meaningful development of a cultural tradition that re-emerged in the second half of the twentieth century.

The rosy dawn of my title refers to that optimistic time when the logical concept of a natural kind originated in Victorian England. The scholastic twilight refers to the present state of affairs. I devote more space to dawn than twilight, because one basic problem was there from the start, and by now those origins have been forgotten. Philosophers have learned many things about classification from the tradition of natural kinds. But now it is in disarray and is unlikely to (...) be put back together again. My argument is less founded on objections to the numerous theories now in circulation, than on the sheer proliferation of incompatible views. There no longer exists what Bertrand Russell called ‘the doctrine of natural kinds’—one doctrine. Instead we have a slew of distinct analyses directed at unrelated projects. (shrink)

Entity realism is the view that ‘a good many theoretical entities do really exist’. The main novelty of entity realism was that it provided an account of scientific realism that did not have to endorse realism about theories—the general proposal was that entity realism is noncommittal about whether we should be realist about scientific theories. I argue that the only way entity realists can resist the pull of straight scientific realism about theories is by endorsing a recent new player in (...) the scientific realism debate: singularist semirealism.

L’histoire de la psychologie en tant que discipline autonome comporte non seulement des développements méthodologiques et institutionnels, mais aussi l’élaboration du concept même de psychologie et des représentations de sa place dans l’ordre des sciences. Si de telles représentations ne détenninent pas la constitution du champ professionnel ou la pratique concrète du psychologue, elles n’en expriment pas moins des idéaux épistémologiques et reflètent les changements qui s’opèrent au sein de la discipline. Nous donnerons d’abord une vue générale de la position (...) de la psychologie au XVIIe et au VXIIIe siècle, puis nous esquisserons l’histoire de sa place dans l’ordre des sciences de Destutt de Tracy à Jean Piaget. Après avoir été la science des sciences des classifications hiérarchiques, la psychologie s’intègre aux autres sciences dans des schémas moins linéaires, voire circulaires, sans pour autant toujours perdre la prééminence gnoséologique et pédagogique que lui attribuèrent en premier les « psychologues » du XVIIIe siècle.

Over time, various thematic classifications have been put forward to organize science into a coherent system of specialized areas of research. From an analysis of the historical evolution of the criteria used to distinguish the sciences from one another, I propose in this paper a quadripartite typology for the different thematic classification systems propounded by scholars throughout the centuries. Basically, I argue that the criteria used to differentiate the sciences have been alternately drawn from their respective subject matters, kinds of (...) knowledge, methods and aims. Then, I show that several reclassifications occurred in the thematic structure of science. Finally, I argue that such changes in the structure of learning displaced the modalities of contact between the objects, knowledge, methods and aims of the various branches of science, with the result of outlining reshaped intellectual territories conducive to the emergence of new areas of research.
