Abstract
This paper explores an analogy between two approaches to teleology in nature and two theories of authorship. I argue that Spinoza’s attempt (as Kant criticizes it in the Third Critique) to explain all natural unity, and explain away apparent teleological unity, in terms of inhering in the same subject (God) or proceeding causally from God’s essence mirrors the view Proust lays out in the essay “Gustave Moreau” that the features of a work of art are unified in virtue of occurring together in, and proceeding from the laws of, the artist’s inner soul. Meanwhile, the strategy Kant favors for understanding interdependent natural systems like organisms—provisionally considering them as purposively designed—resembles the one Alexander Nehamas recommends in “The Postulated Author” (1981) for interpreting a work of art: imagining the agent who could have intended all its features. I propose that this analogy sheds light on the unity of the two parts of the Third Critique by pointing to the similarity between interpreting beautiful objects and interpreting nature.
