Abstract

This paper focuses on Gundissalinus’s particularly important contribution to metaphysics which it presents in three steps: firstly, a succinct overview of the history of the relevant metaphysical terminology from the Late Ancient period to the Middle Ages shows how, for the first time, Gundissalinus interpreted metaphysics as the name of a discipline ; in a second step, the paper analyzes the specific epistemological foundation of metaphysics as an autonomous science, namely as ontology, in the chapter on metaphysics in Gundissalinus’s De divisione philosophiae, paying particular attention to his criticism of twelfth-century theology as this was developed in the School of Chartres; thirdly, the paper examines a crucial text from the treatise on the division of the sciences: in it, Gundissalinus included an otherwise unknown translation of a passage from Avicenna’s Book of Demonstration which discusses the thorny issue of the subordination of the philosophical disciplines to metaphysics. This subject is one which would continue to receive plenty of attention in later times, as the examples of Robert Kilwardby and John Duns Scotus demonstrate, both of which authors may be considered to have continued Gundissalinus’s metaphysical project
