NOTES FROM KANT'S "THE CRITIQUE OF PURE REASON"

1. No Knowledge is Antecedent to Experience; it begins with it.

2.  Whether there exists some knowledge altogether independent of experience, and even of all sensuous impressions? Knowledge of this kind is called a priori, in contradistinction to empirical knowledge, which has its sources a posteriori, that is, in experience.

3. The existence of a priori knowledge, a posteriori knowledge 

4. Pure and impure a priori knowledge.
