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 arise or come to be in a series. In particular, the author shows how William of Auvergne uses two categories to argue against this conception of fate: one that defines the substance and another that outlines the function.
