Kant’s longstanding interests in science have been well-documented. There are numerous studies devoted to Kant’s early work on cosmology in his Universal Natural History and Theory of the Heavens (1755), and of course also to his interests in physics and his work on forces (1747), axial rotation (1754), the ages of the earth (1754), fire (1755), earthquakes (1756), winds (1757), and even to his discussion of volcanoes on the moon (1785). It is well-known, moreover, that part of Kant’s work in the Critique of Pure Reason (1781) was to ground the certainty of scientific claims against Hume’s skepticism, and that Kant’s program for securing our experience of the natural world extended to his later account of the Metaphysical Foundations of Natural Science (1786). Less well-known, however, is the realization that Kant’s apparent bias toward the hard sciences has lain rather more in the interests of Kant scholars, than in Kant himself.

Kant's 1772 letter to Markus Herz is celebrated for its marking the ‘Critical turn’ in Kant's thought, a turn that would move Kant away from the speculative metaphysics of the 1750s towards the Critical philosophy of 1781. It is here, seemingly for the first time, that Kant asks the question concerning the relationship between concepts and objects, telling his former pupil that the answer to this question ‘constitutes the key to the whole secret of hitherto still obscure metaphysics.’ For anyone interested in the development of Kant's thought this makes for exciting news since it is the posing of this question that marks Kant's first step towards the Critique and it is the answer to this question that will come to identify the ‘objective portion’ of the Transcendental Deduction, a text that already begins with a rehearsal of points raised in Kant's letter. But while the letter to Herz is clearly itself a key to what Kant sees as the ‘whole secret of hitherto still obscure metaphysics’, the question concerning concepts and objects itself poses interpretive problems that need to be addressed. Above all, one needs to ask how Kant arrived at such a question

This edited collection began as an international symposium on Kant and biology held at the University of Tübingen in 2010 and the now-published volume offers us new ways of thinking about Kant’s theory of biology with respect to not only his own work but to contemporary discussions regarding biological function and form. With a consistently high level of scholarship and a set of internationally renowned contributors, Kant’s Theory of Biology thus offers us an important contribution to the field’s rapidly growing interest in the history of the life sciences, and the book’s discussions devoted to the Critique of Judgement, in particular, will no doubt shape the course of subsequent investigations in the years to come. The anthology contains fifteen essays divided into three parts, with a focus on the development of the philosophy of biology in Kant’s early writings, the theory of organisms in Kant’s Critique of Judgement, and current perspectives on the teleology of nature. The quality of the editing on this book is excellent, far superior to that of a typical anthology, and what is to be especially appreciated is the helpful cross-referencing being done by the majority of the papers in so far as this lends the collection an organic, as opposed to a merely aggregative, feel.

Kant’s Organicism: Epigenesis and the Development of Critical Philosophy, traces the decisive role played by eighteenth century embryological research for Immanuel Kant’s theories of mind and cognition. I begin this book by following the course of life science debates regarding organic generation in England and France between 1650 and 1750 before turning to a description of their influence in Germany in the second half of the eighteenth century. Once this background has been established, the remainder of Kant’s Organicism moves to the influential role played by models of embryological development for Kant’s approach to understanding the cognitive processes responsible for the generation of knowledge, with special attention paid to Kant’s Precritical writings in the 1760s and 1770s. The book closes with a reinterpretation of Kant’s transcendental deduction in the Critique of Pure Reason.

Abstract: This essay addresses three specific moments in the history of the role played by intuition in Kant's system. Part one develops Kant's attitude toward intuition in order to understand how ‘sensible intuition’ becomes the first step in his development of transcendental idealism and how this in turn requires him to reject the possibility of an ‘intellectual intuition’ for human cognition. Part two considers the role of Jacobi when it came to interpreting both Kant's epistemic achievement and what were taken to be the outstanding problems of freedom's relation to nature; problems interpreted to be resolvable only via an appeal to ‘intellectual intuition’. Part three begins with Kant's subsequent return to the question of freedom and nature in his Critique of Judgment. With Goethe's contemporaneous Metamorphoses of Plants as a contrast case, it becomes clear that whereas Goethe can embrace the role of an intuitive understanding in his account of nature and within the logic of polarity in particular, Kant could never allow an intuition of nature that in his system would spell the very impossibility of freedom itself
