Abstract

In Critique of the Power of Judgment, Kant claims organisms are to be judged as ‘natural ends’, which are products of nature but inexplicable by mechanical laws of nature. The conception of natural ends necessarily leads to the idea of nature in its whole as a system of ends. This paper proposes an interpretation of Kant’s biological teleology that can be compatible with modern science. Mechanical laws in the third Critique are understood as empirical causal laws that determine all phenomena. A living organism is mechanically inexplicable, not because it falls outside of mechanical laws, but because the reciprocal productions of its parts are unifiable under its whole, as if designed by an intelligent agency according to the concept of the whole. Once we judge teleologically the mechanical laws determining the organic productions, we must judge teleologically all productions determined by these laws and therefore conceive nature in its whole as a system of ends, to which natural mechanism is subordinated.
