Living natural products in Kant's physical geography.

In this paper I propose a new account of living natural products in Kant's physical geography. I argue that Kant adopts Buffon's twofold conception of natural history, which consists of a general theory of nature as a physical nexus of causes and a particular account of living natural products in the setting of the earth. Yet in contrast to Buffon, who placed the two parts of natural history on equal epistemic footing, Kant's physical geography can be understood as a second, pragmatic level of inquiry that stands under the formal conditions of nature outlined in Universal Natural History. On the higher, formal level, natural history provides a physical account of time and space as an expanding causal sequence. On the lower, pragmatic level, physical geography provides a causal account of particular natural products as developing within a specific place. I argue that this two-tiered account not only clarifies the relation between metaphysics and experience in Kant's pre-critical philosophy, it also sheds light on the continuity between the method of physical geography and the systematisation of nature presented in the critical philosophy.
