Posterior Analytics   

primary premisses are more knowable than demonstrations, and all
scientific knowledge is discursive. From these considerations it
follows that there will be no scientific knowledge of the primary
premisses, and since except intuition nothing can be truer than
scientific knowledge, it will be intuition that apprehends the primary
premisses-a result which also follows from the fact that demonstration
cannot be the originative source of demonstration, nor,
consequently, scientific knowledge of scientific knowledge.If,
therefore, it is the only other kind of true thinking except
scientific knowing, intuition will be the originative source of
scientific knowledge. And the originative source of science grasps the
original basic premiss, while science as a whole is similarly
related as originative source to the whole body of fact.
