Abstract
The paper deals with the metaphysics of Valerian Magni, a seventeenth-century Capuchin thinker and Church politician. It follows Stanislav Sousedik’s and Paul Richard Blum’s interpretations of Magni’s thought and aims to systematize Magni’s metaphysical notions and present their gradual development. The paper first focuses on Magni’s critique of Aristotelianism, which the Capuchin regards as an atheistic philosophy due to incorrect conceptions of God and the world. Then, Magni’s attempt to create a metaphysical system in his late work Opus philosophicum in particular is presented. The influence of the Augustinian-Bonaventurian tradition and the subjectivist tendencies in Magni’s thought are taken into account.
