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.

I analyze the epistemic strategies used by paleontologists (between 1830–1930) to reconstruct features of ancient organisms from fossilized bodies and footprints by presenting two heuristics: (1) a “claim of harmony” which posits the harmonious interaction of natural objects in order for complex systems to be simplified and (2) the “kintsugi heuristic” which is used inter-theoretically to explore new claims of harmony. I apply these to three successive historical cases: Georges Cuvier’s laws of correlation, the panpsychist paleontology of Edward Drinker Cope, (...) and the single-character approach of Henry Fairfield Osborn.

This paper investigates the complexity hypothesis in microbial evolutionary genetics from a philosophical vantage. This hypothesis, in its current version, states that genes with high connectivity are likely to be resistant to being horizontally transferred. We defend four claims. There is an important distinction between two different ways in which a gene family can persist: vertically and horizontally. There is a trade-off between these two modes of persistence, such that a gene better at achieving one will be worse at achieving (...) the other. At least some genes are likely to experience selection favoring increased transferability. One consequence of this can be encapsulated as the “simplicity hypothesis”: horizontally persisting genes will experience selection favoring reduced connectivity. In order to make sense of the simplicity hypothesis, we need to consider evolutionary populations that transcend species boundaries. Vertical and horizontal persistence are therefore not two competing ways of succeeding at the same game, but involve playing two different games altogether. The complexity hypothesis can be understood in terms of two related notions: entrenchment and Cuvierian functionalism. This framing reveals previously unrecognized and philosophically interesting connections between reasoning about deep conservation and horizontal transfer. (shrink)

This paper traces conceptual links between the works of Georges Cuvier and Auguste Comte. The primary conceptual link between the two, and the focus of this paper, is the ‘principle of the conditions of existence’. This principle lies at the heart of Cuvier's theoretical biology and it was adopted by Comte, in modified form, to serve as a foundational concept for his comprehensive and biologically oriented natural philosophy. Contrary to popular interpretations of Cuvier's thought, it is argued that both Cuvier (...) and Comte understood the principle of the conditions of existence as the basis for a non-teleological form of explanation and a properly scientific alternative to the metaphysics of final causation. This conceptual link is historically significant, for the principle of the conditions of existence was also an important concept for French physiologists of the second half of the nineteenth century, including Claude Bernard, who were highly influenced by Comte's natural philosophy. Tracing the legacy of Cuvier in Comte's natural philosophy should thus clarify the work of both of these thinkers while bringing into focus an important line of nineteenth-century conceptual development.

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)

This paper seeks to show Kant’s importance for the formal distinction between descriptive natural history and a developmental history of nature that entered natural history discussions in the late eighteenth century. It is argued that he developed this distinction initially upon Buffon’s distinctions of ‘abstract’ and ‘physical’ truths, and applied these initially in his distinction of ‘varieties’ from ‘races’ in anthropology. In the 1770s, Kant appears to have given theoretical preference to the ‘history’ of nature [Naturgeschichte] over ‘description’ of nature (...) [Naturbeschreibung]. Following Kant’s confrontations with Johann Herder and Georg Forster in the late 1780s, Kant weakened the epistemic status of the ‘history of nature’ and gave theoretical preference to ‘description of nature’. As a result, Kant’s successors, such as Goethe, could draw from Kant either a justification for a developmental history of nature, or, as this paper argues, a warrant from the critical philosophy for denying the validity of the developmental history of nature as anything more than a ‘regulative’ idea of reason.

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.

As many cultural historians of the sciences have recently indicated, eighteenth-century illustrations of natural historical works represent an important source that can be used to explore the ways in which nature and the study of nature were regarded in the period. Naturalistic illustrations, however, are not the only genre of images that may help the historian in this investigation. Another interesting source is represented by images of nature and natural objects connected with fictional literature. Yet, little attention has been devoted (...) so far to this genre of images. In this paper I analyse some of the engravings which illustrate Retif de la Bretonne's imaginary voyage La Decouverte australe par un homme volant. My aim is to show that these illustrations convey a well-defined image of the natural universe, and that their analysis may contribute to our understanding of the various significances and roles attached to Nature in the period-particularly bringing to the fore its moral and political uses. Further, by analysing the ways in which they connect and integrate a variety of artistic and discursive traditions related to fiction, travel, and natural history, I hope to suggest some of the ways in which this genre of images may be used to shed light on the eighteenth-century interplay between spheres of knowledge later assigned to such distinct disciplines as 'science', 'literature', or 'art'.
