Abstract
The notion of productive imagination is not only of crucial importance for Kant’s idea of pure reason, and for the unity of our theoretical experience, it is also stunningly seminal for post-Kantian philosophy: think, for instance, of Fichte, Schelling, the German Romantics, and of Hegel’s Glauben und Wissen. For the historian of philosophy, in particular, it is a very intriguing notion. Yet, however fundamental the notion of productive imagination is, it is not easy to determine its precise role in the Critique of Pure Reason; the question of its historical genealogy is even more obscure.
