Abstract

On the historiographic plane, the confrontation between the texts of Bonaventure and of Thomas Aquinas regarding the structure of human knowledge, reveals common features and divergent ones. Both are, moreover, «scholastics» in the elaboration of the sources, in so far as they do not select only some data of tradition , but seek through various paths to assume and to synthetise coherently the whole tradition known to them. Bonaventure has followed the path of extrapollation of the single data from their original context and of their insertion into a schema altogether traditional as to the content, but altogether new as for the structure. Thomas, on the contrary, has chosen the way of composition of the data through the concordance and the hierarchy of the schema, giving clearly the epistemological primacy to the Aristotelian system, but without showing himself ever fully satisfied with the schemata obtained. In articulating philosophy and theology Thomas et Bonaventure share the paradigm of the «double in parallel», bringing it perhaps to the extreme rigour, though with different nuances: Thomas by showing the natural basis of the supernatural perfection, and Bonaventure by showing the necessity and the natural impossibility of such perfectioning
