I. Kant: Cognitive Capacity as World Structure We live in a world where there are many objects like animals, plants, stones, human beings, with which we have to handle. Everyday we see them, touch them, we feel confident of their existence. For all of us they are an unquestionable fact. However as soon as we try to explain precisely how we obtain this knowledge, we get embarrassed. Then we usually argue that it comes from processing information which our senses receive. That seems the most likely plausible standpoint. Our organism obtains information from outside and build from it the world as we daily perceive. Nevertheless that answer was already given by British empiricists who ran into a dilemma: they presumed that the sense data coming from the outside were the only authentic information about the world. Unfortunally that was a presupposition: the belief that the sense data present the world as it is.
