In this interest of time, I’ll just say something directly: this is an incredible book. Reading it, thinking it through, is extremely rewarding. I haven’t read a work of philosophy that had as much impact on me since being in school myself. The book presents you with new ideas and connections and it forces you to see philosophy and its history in new ways, even if you (like me) had been quite attached to your old ways. The book got into my head. Now I find myself, in idle moments, arguing with Paul up there in my head; as if there is a little copy of him in there now, making the case for his versions of inferentialism and cognitive contextualism. Fortunately, Paul is in my experience unfailingly nice, generous and sympathetic even in argument—otherwise it might not be as nice to have a copy of him in your head. Still, the copy pales in comparison to the original, so it is great to be here.

Kant’s treatment of teleology and life in the Critique of the Power of Judgment is complicated and difficult to interpret; Hegel’s response adds considerable complexity. I propose a new way of understanding the underlying philosophical issues in this debate, allowing a better understanding of the underlying structure of the arguments in Kant and Hegel. My new way is unusual: I use for an interpretive lens some structural features of familiar debates about freedom of the will. These debates, I argue, allow us to see more clearly the underlying structure of a great many philosophical issues. Aside from some suggested avenues of approach, however, I do not aim to interpret what Kant or Hegel has to say about freedom of the will. The idea is to use this interpretive lens to better understand the philosophical issues at stake in their disagreement concerning teleology and life. This will clarify the precise philosophical burden that must be met by Kant’s argument in defense of his skepticism, and why his case has considerable philosophical force. But it will also explain why Kant’s argument itself inevitably provides the opening for Hegel’s reply, and sets a standard that Hegel will meet in a surprising way. Finally, this approach will explain why we can learn a great deal from the philosophical arguments in Kant and Hegel about this topic, despite the intervening years of such great progress in the biological sciences: by looking to Kant and Hegel we can better understand the structure of underlying philosophical terrain of the issues concerning teleology and life—terrain we are still fighting over today.

Kant’s position on teleology and biology is neither inconsistent nor obsolete; his arguments have some surprising and enduring philosophical strengths. But Kant’s account will appear weak if we muddy the waters by reading him as aiming to defend teleology by appealing to considerations popular in contemporary philosophy. Kant argues for very different conclusions: we can neither know teleological judgments of living beings to be true, nor legitimately explain living beings in teleological terms; such teleological judgment is justified only as a “problematic” guideline in our search for mechanistic explanations. These conclusions are well supported by Kant’s defense of his demanding analysis, according to which teleological judgment literally applies to a complex whole only where teleology truly explains the presence of its parts.

My focus here is on what Hegel has to say about nature and natural kinds, in ‘Observing Reason’ from the Phenomenology, and also in similar material from the Logic and Encyclopedia. I intend to argue that this material suggests a surprising way of stepping beyond the fundamental debate. There can of course be no question of elaborating and defending here a complete interpretation of Hegel’s entire theoretical philosophy. I will have to restrict myself to arguing for the unlikely conclusion that there is an approach that can combine and integrate the strongest points made by both sides in the most basic debate shaping recent Hegel interpretation. What needs explaining is how there could be any single coherent position that in any philosophical sense both cancels and preserves metaphysics
