Non stultam concludentes. Giordano Bruno e il ricorso a David de Dinant tra il De la causa e il De vinculis

This research retraces and analyses the use by Giordano Bruno of his indirect source, David de Dinant, recurrent in the ontological reflection developed in De la causa, principio et Uno and in De vinculis in genere. By examining the texts of Bruno’s direct sources, such as Albertus Magnus, Thomas Aquinas, Nicolas of Cues and Marsilio Ficino, this research reconstructs, first of all, the channels through which Bruno reads and transposes the heretical and censured doctrine of David de Dinant. Secondly, this research examines Bruno’s reformulation of some of the major questions discussed by his indirect source : 1) the link or identity and unity of hyle and mens, matter and form, power and act ; 2) the accidental nature of sensible forms and the eternity or the permanence of an infinite being and substance that is not subject to change. Finally, the research shows how Bruno’s use of the doctrine of David de Dinant, and with it of the pre-Socratic, Eleatic and atomistic philosophies, represents an attempt to think a philosophical and ontological alternative to the Aristotelian theological-metaphysical scholastic-thomistic structure.
