Abstract

Kant’s Transcendental Ideal (TI) is presented in a notoriously obscure section of the Critique of Pure Reason. Many readers know that Kant’s principal purpose in the TI is to show how reason fallaciously derives its concept of God from its idea of the world. But this argument is clothed in a language that is unfamiliar even to skilled commentators on Kant’s work. In this essay, I present the historical context of the proof, conduct a detailed exegesis of the proof, and argue that Kant formulated the Transcendental Ideal in such a way as to avoid Spinozism—a point Kant later seems to have doubted could be avoided. I develop my case in light of some comments made in a lesser-known essay that Kant wrote for the 1795 contest of the Royal Academy of Sciences in Berlin.
