Fato, necessità e causalità astrale in Guglielmo d'Alvernia

This essay deals with William of Auvergne's arguments against astral causality and necessity. The astral causality identically operates on the individuals with the same nativity, influencing their dispositions and determining human actions. The necessity or eimarmene, namely fate, is caused by which things connected to others that arise or become a series. This essay particularly focuses on showing how William of Auvergne uses two categories to argue against this conception of fate: one that defines it as a substance and another that outlines it as a function.
