Robert Grosseteste and Eustratius of Nicaea on Concept Formation after the Fall

Main Article Content

Michele Trizio


This paper explores the similarities between a crucial passage in Robert Grosseteste’s commentary on Posterior Analytics and the commentary on Nicomachean Ethics 6 written by the Byzantine commentator Eustratius of Nicaea (d. ca. 1120). According to the present author, Eustratius may be the direct source of Grosseteste’s epistemology and concept formation theory in the commentary. A tentative revision of the chronology of Grosseteste’s Greek studies may be necessary to account for the relationship between the two texts.
