 Henry of Ghent (late 13th C.) is the first medieval philosopher both to have obvious knowledge of the Academica, and to have made a serious philosophical attempt to come to grips with the views expressed there. When John Duns Scotus critiques Henry’s epistemology, he shows no evidence of knowing Cicero’s text. And for the most part, later medievals were equally ignorant of it. Their discussions of skepticism seem not to have been based on an examination of or engagement with skepticism as presented by ancient authors; it was a skepticism of its own sort, as will be detailed below.
