Il principio dell’unicità del vero dalla bolla Apostolici regiminis (1513) alla Rivoluzione scientifica

On December 19^th 1513, the papal bull Apostolici regiminis sanctioned the dogma of the immortality of the soul, imposing the defence of the Christian doctrine during the courses in philosophy. In their lectures, the Christian teachers had to contrast some unorthodox topics such as the mortality of the individual soul, the unity of the intellect and the eternity of the world. All of their arguments should be based on the principle of the unity of truth (verum vero minime contradicit), according to which philosophical truths cannot deny or contradict truths of the faith. The paper aims to trace the history of the reception of the adagio verum vero minime contradicit, starting from the promulgation of the bull and the debate on the Aristotelian psychology up to the Age of Galileo and Scientific Revolution, showing the important role Benet Perera played in this debate.
