For post-Kantian philosophy, “life” is a transitional concept that relates the realm of nature to the realm of freedom. From this vantage point, what is living seems to have the double char- acter of being both already and not yet free: Compared with the external necessity of dead nature, living beings already seem to exhibit a basic type of spontaneity and normativity that on the other hand still has to be superseded on the path to the freedom and normativity of (...) spirit. The origin of this constellation is to be found in Kant’s discussion of natural purposes in the third Critique; its most articulated shape, however, is developed in Hegel’s conception of life. To introduce the questions that this volume discusses, I will briefly characterize the way in which Kant opens up this conception of the living (I) and outline the way in which Hegel develops this approach (II, III). I will close with a brief outlook on the contributions collected in this volume (IV). (shrink)
