From an Aristotelian point of view, the works of nature result from an ordering of ends. In modern terms, nature for Aristotle is not “value free”, and I take this to be a good thing. But from a strict Kantian point of view, we are the bearers of value, and the attribution of ends to nature independent of us is only a kind of beneficial heuristic projection. But if we radicalize the Kantian primacy of practical reason in the way that Brandom sees Hegel as doing, then all our theoretical accounts of nature, including those commonly regarded as value-free — and everything else we think, feel, and do — ultimately have a dependency on our inquiries into value and normativity.
From a Kantian point of view, our only access to objective nature is through our rational, discursive understanding. The very objectivity we attribute to nature depends on the objectivity of our understanding of it. Objectivity itself is a normative attitude. I think Kant and Aristotle ultimately agree in recognizing that we don’t have direct access to how things are in themselves, and that how things are in themselves is always a matter of discursive inference, in which the last word is never said.
Hegel emphasizes that the objectivity of understanding we achieve in this way is not a private possession, but something larger than us in which we participate. (See also Teleology After Kant.)
