Nota sul concetto di 'formalità dialogico-procedurale' come base per una 'metafisica aperta' in Tommaso d'Aquino

This contribution aims, on the one hand, to present the results of my research on the structures of the free and creative act in Thomas Aquinas’ ethics, on the other hand, to discuss whether Thomas’ metaphysics can be encompassed as ‘open metaphysics’. In such an approach the first cause is not so much the fundamental rule of human acting, but rather the open space of acting itself in the human being, so that he can be causa sui and, hence, free.
