Does not concern itself with objects themselves with a view of deriving concepts from them directly.
All judgments require reflection.
Agreement and opposition. Inner and outer. Whether things are identical or different, in agreement or opposition, etc., cannot be established at once from the concepts themselves by mere comparison, but solely by means of transcendental consideration of the cognitive faculty to which they belong. Therefore, the interrelations of given representations can only be determined through transcendental reflection. If an object of pure understanding is presented to us on several occasions, it is only one thing.
