After reading about transcendental Aesthetics and transcendental logic, I perceive three kinds of unity in Kant's Critique of Pure Reason:
Unity of properties of an object which is sensed through apperception, followed by combination/unification
Unity of empirical ego which enables the first unity and reflection
Unity of pure ego (transcendental ego) which exists in every situation and basically enables reflection and any other unification
Are these categorizations right? Or did I misunderstand anything fundamental?
