The article surveys Kant’s treatment of biological teleology in the ’Critique of Judgment’, with special attention to the question of whether the notion of natural teleology is coherent. It argues that our entitlement to regard nature as teleological is not established by the argument of the ’Antinomy’, but rather results from our entitlement to regard the workings of our own cognitive faculties in normative terms. This implies a view of the relation between biological teleology and the representational character of mind (...) which is the reverse of that adopted by naturalistic theorists of mind like Fred Dretske and Ruth Millikan.

Thought experiments de facto play many different roles in biology: economical, ethical, technical and so forth. This paper, however, is interested in whether there are any distinctive features of biological TEs as such. The question may be settled in the affirmative because TEs in biology have a function that is intimately connected with the epistemological and methodological status of biology. Peculiar to TEs in biology is the fact that the reflexive, typically human concept of finality may be profitably employed to (...) discover mechanical-experimental causal relations in all living beings—with the obvious caveat that we do not hypostatise and interpret this concept as an ontological quality, since this would land one in an implicitly animistic, pre-Galilean view of nature. From a methodical point of view, the concept of finality is an essential assumption as well as a powerful heuristic tool in the practice of biology, that is, in the investigation of living beings in an intersubjectively testable and reproducible way.

This essay discusses how, for Hegel, freedom can be realized in nature in a rudimentary fashion in solar systems. This solves a problem in Kant’s account of freedom, namely, the problem that Kant only gives a negative argument for why freedom is not impossible but does not give a positive account of how freedom is real. I give a novel account of Kant’s negative argument. Then, I show how, according to Hegel, solar systems can be considered as exhibiting freedom in (...) a rudimentary fashion. Finally, I lay out how Hegel systematically develops this point about the freedom of solar systems in the ‘Mechanism’-chapter of the Science of Logic. In doing so, he uses Kant’s negative argument in a ‘purified’ form to arrive at an account of an ‘intimate token-type relation’ between the planets in a solar system and the law that governs their motion. The essay as a whole provides a concrete example of how Hegel is an inheritor and radicalizer of Kant, both with respect to freedom’s reality and with respect to philosophical method. (shrink)

A well-rehearsed move among teleological realists in the philosophy of biology is to base the idea of genuinely teleological forms of organic self-reproduction on a type of causality derived from Kant. Teleological realists have long argued for the causal possibility of this form of causality—in which a whole is considered the cause of its parts—as well as formulated a set of teleological criteria of adequacy for it. What is missing, to date, is an account of the mereological principles that govern (...) the envisioned whole-to-part causality. When the latter principles are taken into account, we find that there is no version of whole-to-part causality that is mereologically, causally and teleologically possible all at once, as teleological realism requires.

Kant -- drawing on his eighteenth-century predecessors -- provided a discerning and powerful characterization of what biologists had to explain in organic form. His difference from the rest is that he opined that was impossible to explain it. Its ’inscrutability’ was intrinsic. The third ’Critique’ essentially proposed the reduction of biology to a kind of prescientific descriptivism, doomed never to attain authentic scientificity. By contrast, for Locke, and ’a fortiori’ for Buffon and his followers, ’intrinsic purposiveness’ was a fact of (...) the matter about concrete biological phenomena; the features of internal self-regulation were hypotheses arising out of actual research practice. The difference comes most vividly to light once we recognize Kant’s distinction of the concept of organism from the concept of life. (edited). (shrink)
