This is the way concepts can relate a priori to objects. Kant says, “If each representation were completely foreign to every other, standing apart in isolation, no such thing as knowledge would ever arise. For knowledge is [essentially] a whole in which representations stand compared and connected.” Kant lays out a threefold synthesis about experience: a synthesis of apprehension in intuition, a synthesis of reproduction in imagination, and a synthesis of recognition in a concept. We should not divide these steps into one but they should all be intertwined as one. So what we see must occur consecutively.Therefore our idea of the Synthetic Unity of Apperception comes into play. This is where every possible content of experience must be accompanied by “I think”. Everything in your mental state should be able to be accompanied by “I think” if not then it will not matter at all. “I think” is not something that consists in sensibility. It is an act of spontaneity. It precedes all possible experience. The unity of this particular manifold is not given in experience but prior to it. Thinking substances can only perceive what is going on inside as perception goes on at all times. This is where our awareness of a manifold comes into play. We are aware of one thing after another. Each impression is different from one other. We must say that these impressions are mine. Basically accompanying them with the phrase “I think”.
