   • 2004, Georges Dicker, Kant's Theory of Knowledge: An Analytical Introduction, page 49:

     As I have already indicated, however, there is reason to think that at least some of the principles that Kant takes to be synthetic a priori are instead unobviously analytic, and so I shall assume that if Kant shows that a principle associated with one of his categories is unobviously analytic, that too shows that the category is objectively valid.
