Abstract
Kant's correspondence with his colleague and zealous disciple, Marcus Herz, was prophetic: only a few will understand the Critique of Pure Reason. Unfortunately, the problems are intractable and the necessary conceptual scheme to deal with the problems requires a "complete change of thinking in this part of human knowledge". But eventually people will "get over the initial numbness" Kant reassures another correspondent, Christian Garve. Fortunately, he suggests, there is a central question at the foundation of his difficult thought - a question that is the key to his ideas. So what is this important question that Kant insists has been "stated clearly enough"? And how clear is it? I explore these issues in my paper.
