Classification in eighteenth-century natural history was marked by a battle of systems. The Linnaean approach to classification was severely criticized by those naturalists who aspired to a truly natural system. But how to make oneself nature''s spokesman? In this article I seek to answer that question using the approach of the French anthropologist of science Bruno Latour in a discussion of the work of the French naturalists Buffon and Cuvier in the eighteenth and early nineteenth century. These naturalists followed very (...) different strategies in creating and defending of what they believed to be a natural classification in zoology. Buffon failed, whereas Cuvier''s work appeared to be very successful. My argument will be that, to explain Buffon''s failure and Cuvier''s success, we should not focus on the epistemological or theoretical concerns and justifications of these naturalists, but on the concrete and heterogeneous means or tools through which animals were mobilized, stabilized and combined into ever more comprehensive systems of classification.

This paper investigates conceptions of explanation, teleology, and analogy in the works of Immanuel Kant (1724-1804) and Georges Cuvier (1769-1832). Richards (2000, 2002) and Zammito (2006, 2012, 2018) have argued that Kant’s philosophy provided an obstacle for the project of establishing biology as a proper science around 1800. By contrast, Russell (1916), Outram (1986), and Huneman (2006, 2008) have argued, similar to suggestions from Lenoir (1989), that Kant’s philosophy influenced the influential naturalist Georges Cuvier. In this article, I wish to (...) expand on and further the work of Russell, Outram, and Huneman by adopting a novel perspective on Cuvier and considering (a) the similar conceptions of proper science and explanation of Kant and Cuvier, and (b) the similar conceptions of the role of teleology and analogy in the works of Kant and Cuvier. The similarities between Kant and Cuvier show, contrary to the interpretation of Richards and Zammito, that some of Kant’s philosophical ideas, whether they derived from him or not, were fruitfully applied by some life scientists who wished to transform life sciences into proper sciences around 1800. However, I also show that Cuvier, in contrast to Kant, had a workable strategy for transforming the life sciences into proper sciences, and that he departed from Kant’s philosophy of science in crucial respects.

A well-established narrative in the history of science has it that the years around 1800 saw the end of a purely descriptive, classificatory and static natural history. The emergence of a temporal understanding of nature and the new developmental-history approach, it is thought, permitted the formation of modern biology. This paper questions that historical narrative by closely analysing the concepts of development, history and time set out in Karl Ernst von Baer’s study of the mammalian egg (1827). I show that (...) Baer’s research on embryogenesis aimed not simply to explain temporal changes, but to inscribe the formation of new individual organisms into a continuous, unending organic process. I confront Baer’s views with other explanations of embryogenesis arising in the 1820s and 1830s, especially those of Jean-Baptiste Dumas and Jean-Louis Prévost and of Theodor Schwann. By highlighting divergences between these scientists, especially as to their view of the role of gender differences in reproduction, I argue that biology evolved not from a homogeneous concept of developmental history but out of various, even opposing, views and research programmes. Thus, the birth of biology did not imply the end of all natural history’s thought models. (shrink)

Lacepède was a key figure in the French intellectual world from the Old Regime to the Restoration, sinc e he was not only a scientist, but also a musician, a writer, and a politician. His brilliant career is a good example of the progress of the social status of scientists in France around 1800. In the life sciences, he was considered the heir to Buffon and continued the latter’s Histoire naturelle, but he also borrowed ideas from anti-Buffonian scientists. He broached (...) many important subjects such as the nature of man, the classification of animals, the concept of species, and the history of the Earth. All these topics led to tensions in the French sciences, but Lacepède dealt with them in a consensual, indeed even ambiguous way. For example, he held transformist views, but his concept of evolution was far less precise and daring than Lamarck’s contemporaneous attempts. His somewhat confused eclecticism allowed him to be accepted by opposing camps of the French scientific community at that time and makes his case interesting for historians, since the opinions of such an opportunistic figure can illuminate the figure of the French intellectual better than more original works could do. In turn, Lacepède’s important social and scientific position gave his views a significant visibility. In this sense, his contributions probably exerted an influence, in particular with regard to the emergence of transformist theories. (shrink)

Already in his lifetime, the naturalist Louis-Jean-Marie Daubenton was dramatically contrasted with his patron and collaborator on the Histoire naturelle (Natural History), Buffon figuring as stylish and prone to hypothesizing, Daubenton as narrow and unwilling to generalize. This caricatural image of Daubenton as an anti-Buffon persists even now. The purpose of this paper is to investigate the development of Daubenton's reputation and then to moderate it by showing that he was not so averse to theorizing or generalization as history has (...) made him. Evidence for this argument comes from the Histoire naturelle and from unpublished manuscripts proving that he originally planned to contribute two synthetic treatises on animal anatomy to the Histoire naturelle. Reconstituting the series as he envisaged it allows a more balanced portrait of one of the founders of comparative anatomy and a look behind the scenes of one of the eighteenth century's most important scientific publications.

ArgumentHere I analyze the anatomical thought of the French physician and naturalist Félix Vicq d'Azyr (1748–1794) in order to bring to light its importance in the development of comparative anatomy at the end of the eighteenth century. I argue that his work and career can be understood as an ambitious program for a radical reform of all biomedical sciences and a reorganization of this whole field around comparative anatomy, on the conceptual as well as the institutional level. In particular, he (...) recommended a close connection between anatomical and physiological studies, and a generalization of the comparative approach towards organs and functions in man and animals. This conception led him not only to reform the scope, the methods, the style of description, and the vocabulary in anatomy, but also to construct a new classification of living beings and to pursue a quest for laws of organization. This strategy was successful, since Vicq d'Azyr was able to promote his thought as well as his institutional position efficiently. The Revolution and his untimely death prevented him from achieving his program, but his attempt would serve as an example for younger scientists like Cuvier. (shrink)

Firstly, in this article it is examined the nature of the putative remarks concerning evolution of species that are found in the works that Richard Owen published before 1858; and then it is made the same thing with the few and vague evolutionist conjectures that Owen certainly made after the public presentation of Natural Selection Theory. Regarding the former topic, the goal will be to highlight the ambiguity of those Owen’s remarks, and concerning the latter topic what is looked for (...) is to show that, when he explained his transmutationist thesis, Owen didn’t go beyond a pious theistic evolutionism, without postulating any mechanism of evolutionary change and remaining faithful to Design Theology praised by Paley.

During the Eighteenth Century – from Bonnet to Robinet, from Maupertuis to Diderot, and up to Buffon – several new topics of discussion were developed concerning materialism, the critique to finalism, the idea of nature as continuous metamorphosis , the advocacy of providentialism, or, to the contrary, of the role of chaos. As a result, scales, prototypes and types have been employed as interpretative hypotheses influencing the main choices and lines of research. In this regard, however, Étienne Geoffroy Saint-Hilaire's work (...) deeply modified the morphological metaphors. The teratologist's eye combined to the mineralogist's perspective established the priority of the material visibility of the living, based on the analysis of its structure rather than of its physiology. The single framework of organistion , on which base every being is formed is thus taken as the condition as well as the limit within which every possible variation in shape is fully justified.
