I address a longstanding problem in Kant scholarship: how is Kant’s use of the term ‘mechanism’ to be understood? It seems that Kant uses that term in a variety of ways, from a narrow sense (“motion communicated between matter”) to a very wide sense (“any causation that is not noumenal”). I argue that Kant has a unified conception of mechanism, where the wider senses are to be understood in light of a conception of nature according to which all of nature (...) is purely mechanistic in the narrow sense. In contrast to his mechanistic predecessors, Kant holds that this conception of nature is an idea, an imaginary end-point of science that we need for orientation but can only approach asymptotically.

Kant’s philosophy of science takes on sharp contour in terms of his interaction with the practicing life scientists of his day, particularly Johann Blumenbach and the latter’s student, Christoph Girtanner, who in 1796 attempted to synthesize the ideas of Kant and Blumenbach. Indeed, Kant’s engagement with the life sciences played a far more substantial role in his transcendental philosophy than has been recognized hitherto. The theory of epigenesis, especially in light of Kant’s famous analogy in the first Critique, posed crucial (...) questions regarding the ‘looseness of fit’ between the constitutive and the regulative in Kant’s theory of empirical law. A detailed examination of Kant’s struggle with epigenesis between 1784 and 1790 demonstrates his grave reservations about its hylozoist implications, leading to his even stronger insistence on the discrimination of constitutive from regulative uses of reason. The continuing relevance of these issues for Kant’s philosophy of science is clear from the work of Buchdahl and its contemporary reception. (shrink)

Kant -- drawing on his eighteenth-century predecessors -- provided a discerning and powerful characterization of what biologists had to explain in organic form. His difference from the rest is that he opined that was impossible to explain it. Its ’inscrutability’ was intrinsic. The third ’Critique’ essentially proposed the reduction of biology to a kind of prescientific descriptivism, doomed never to attain authentic scientificity. By contrast, for Locke, and ’a fortiori’ for Buffon and his followers, ’intrinsic purposiveness’ was a fact of (...) the matter about concrete biological phenomena; the features of internal self-regulation were hypotheses arising out of actual research practice. The difference comes most vividly to light once we recognize Kant’s distinction of the concept of organism from the concept of life. (edited). (shrink)

The aim of this paper is to show firstly why Kant believes we should hang on to teleology, and, secondly, that his views on the matter are still relevant to contemporary epistemology despite the fact that theories of evolution now allow purely mechanical explanations of organic processes. By considering Kant’s account in light of that of Daniel Dennett, I elucidate what I believe to be the strength of Kant’s theory, namely, the pragmatic role it assigns to reflective teleological principles. (edited).

In the Appendix to the Transcendental Dialectic, Kant formulates teleological principles, or rather ideas, and explicates them referring to concrete examples of natural science such as chemistry, astronomy, biology, empirical psychology, and physical geography. Despite the increasing interest in the systematic relevance of the Appendix to the Transcendental Dialectic and its importance for Kant’s conception of natural science, the numerous historical sources for the regulative use of reason have not yet been investigated. One that is very central is Maupertuis’ principle (...) of least action. In 1781, Kant transformed teleology into heuristics and methodology, but in doing so, he partially develops a teleology which was disqualified by Maupertuis because its starting point lies in the construction of animals or plants, the structure of the earth, and the immensity of the celestial bodies. Based on Maupertuis’ principle of action, it can be shown that the Appendix forms a systematic interface between Universal Natural History and Theory of the Heavens and Critique of Judgement which allows the reconstruction of Kant’s regulative use of reason and its specific status in the context of natural science and his critical appraisal of Maupertuis.

While Kant introduces his critical philosophy in continuity with the experimental tradition begun by Francis Bacon, it is widely accepted that his Copernican revolution places experimental physics outside the bounds of science. Yet scholars have recently contested this view. They argue that in Critique of the Power of Judgment Kant’s engagement with the growing influence of vitalism in the 1780s leads to an account of nature’s formative power that returns experimental physics within scientific parameters. Several critics are sceptical of this (...) revised reading. They argue that Kant’s third Critique serves precisely to deflate the epistemological status of experimental physics, thereby protecting science from the threat of vitalism. In this paper I examine Kant’s account of science in the context of the experimental tradition of philosophy, particularly in relation to the generation dilemma of the eighteenth century. I argue that Kant does not deflate the epistemological status of experimental physics but rather introduces systematicity to the experimental tradition. By identifying the reflective use of reason to organize laws of experience into a systematic whole, Kant aims to ground experimental inquiry on the secure course of a science, opening a conception of science as a research programme.

As reflexões metodológicas de Poincaré sobre a modelação mecânica dos fenômenos, as teorias físicas, a hierarquização das leis e a evolução do seu estatuto e sistema são susceptíveis de uma leitura kantiana que exibe a função constitutiva das matemáticas e a função reguladora dos princípios de conveniência e dos princípios da física, correspondendo estes a uma importante etapa na evolução das teorias físicas. The methodological reflections of Poincaré on the mechanical modeling of phenomena, physical theories, the hierarchy of laws and (...) the evolution of their status and system are illuminated by a Kantian reading that displays the constitutive function of mathematics and the regulative function of principles of convenience and of the principles of physics, these corresponding to an important step in the evolution of physical theories.
