ABSTRACT
Four great dualities dominate Kant's theory of the nature of human experience: the duality of appearances and of things as they are in themselves; of intuitions and concepts; of the a priori and the empirical; of the inner and the outer. All four of them appear in the first major section of the work, the Transcendental Aesthetic. It is by way of the duality of intuitions and concepts that we approach the task of trying to understand how they are there related.
