John Duns Scotus

“If all men by nature desire to know, then they desire most of all the greatest knowledge of science. And he immediately indicates what the greatest science is, namely the science which is about those things that are most knowable. But there are two senses in which things are said to be maximally knowable: either because they are the first of all things known and without them nothing else can be known; or because they are what are known most certainly. In either way, however, this science is about the most knowable. Therefore, this most of all is a science and, consequently, most desirable.”
