@JLNobody,
Quote:It seems to me that Kant confined human knowledge to what humans can sense.
From what I remember, he divided it into "before senses" and "after senses". The words used in Norwegian translations are "a priori" and "a posteriori". I do not know if they are the same in English.
A priori knowledge are logical conclusions from definite facts, or experience achieved through reason alone. He talks about the transcendental prerequisites for all empirical perception; those acknowledgments of reason that enable empirical perception. Concepts like time and space are a priori, because it is not possible to make an acknowledgment without recognizing these.
That which is a priori is always valid and neccesarily always true. The way I understand it, these things are "hardwired" into us as part of the "human condition".
There are many problems with his view, especially in light of discoveries and ideas that came later, but as far as I know, Kant was the first of western philosophers who thought in terms of certain aspects of experience being supplied by the perceiver. Perhaps this is the beginning of the divide between "absolute reality" and "human reality"? To me, the consideration that human beings are inseparable parts of reality makes the distinction superfluous.
