Judgments: Perception vs. Experience

In the second part of Prolegomena, Kant discusses the difference between judgments of perception and judgments of experience. He says that judgments of perception are only "subjectively valid" and that they "only require the the logical connection of perception in a thinking subject." (sect. 18) He goes on to say that all of our judgments are "at first merely judgments of perception; they hold good only for us." (sect. 18) Kant then discusses judgments of experience and says that if they have objective validity, then they are empirical judgments. He says that those judgments always require special concepts originally generated in the understanding, which make the judgment of experience objectively valid.

Kant is basically showing the difference between things in themselves and our perceiving mind. Judgments of perception are joining and associating two or more intuitions with each other and making a connection between them. They deal with our senses. He says that we turn judgments of perception into judgments of experience by using concepts of pure understanding because empirical intuitions in themselves cannot be generalized.
