Thesis title: L'immaginazione operativa in Giordano Bruno
Bruno’s entire philosophical production opens with De umbris idearum (1582) and closes with De imaginum compositione (1591), two mnemonic works that demonstrate how his interest in the ars never waned. Far from being conceived as a mere technical exercise, it represents a field of application in which Bruno theorizes a “controlled” vis imaginativa, closely connected with rational activity. The Brunian project thus combines practical utility with a truly metaphysical aim, making memory the privileged vehicle for the emulation of the natural magisterium. The research, therefore, develops within a perspective that seeks to investigate the praxis from De umbris idearum to De imaginum compositione, through the mediation of the Sigillus sigillorum, in constant dialogue with the principles of the “Nolana filosofia.” Therefore, the concepts of umbra, contractio, and idea are the subjects of further investigation, while, from a technical point of view, the focus concerns the use of the circular wheels and the imaginative atrium. Through the analysis of these Latin books, this works aims to show how imagination functions as the living speculum of the universal mind and as a philosophical praxis that unites metaphysics and ethics in the pursuit of divine similitude.
