Given the central place organisms occupy in Kant’s account of living nature, it might seem unlikely that his claims about biological wholes could be relevant to current debates over the problem of biological individuality. These debates acknowledge the multiple realizability of biological individuality in vastly different forms, including parts of organisms and complex groups of organisms at various levels of the biological hierarchy, sparking much controversy in attempts to characterize a biological individual. I argue that, far from being irrelevant to (...) this controversy, Kant’s account provides a key insight for addressing the multiple realizability problem. I show how the reciprocal causality between a self-organizing whole and its parts, which Kant thinks characterizes a natural end, is not limited to organisms but is exhibited by numerous types of beings in living nature. Self-organizing wholes of various kinds, and at various biological levels, may count as biological individuals, depending on the degree to which their functionally integrated parts are represented by reflective judgement as a natural end.

This article offers a constructive reading of the ‘Teleology’ chapter in Hegel's Science of Logic. I argue that it contains an apparently conclusive case for the abstract concepts of means and end (in the sense of ‘purpose’), which has remained unrecognized in the literature. I then show some implications of the fact that the argument is entirely abstract in Hegel's system.

In this article, I discuss the specific ways in which Hegel's account of life and organisms advances upon Kant's account of natural purposes in the third Critique. First of all, I argue that it is essential for Hegel's account that it contains two levels. The first level is that of logical life, the discussion of which does not depend on any empirical knowledge of natural organisms. I provide my reconstruction of this logical account of life that answers to the objection (...) made by a number of Hegel scholars to the effect that Hegel does in fact rely on empirical knowledge at this place in the logic. The second level is that of natural organisms themselves. I argue that it is with the help of this separation of the logical and natural levels, as well as his doctrine of the impotence of nature, that Hegel, unlike Kant, (a) is able to claim that not everything in natural organisms is purposive, and (b) provide a philosophical, and not merely empirical, account of the distinction between plants and animals. In both of these respects, Hegel's position can be seen as a welcome advance over Kant. (shrink)

We characterize Hegel’s stance on biological purposiveness as consisting in a twofold move, which conceives organisms as intrinsically purposive natural systems and focuses on their behavioral and cognitive abilities. We submit that a Hegelian stance is at play in enactivism, the branch of the contemporary theory of biological autonomy devoted to the study of cognition and the mind. What is at stake in the Hegelian stance is the elaboration of a naturalized, although non-reductive, understanding of natural purposiveness.
