The idea underlying the current article as well as our research work refers to will as a source of freedom and, implicitly, of the evil that dominates the current world. Moreover, the weakness of the will could generate the decline of morality and the decline of being that the world is facing today. Starting from philosophical texts and reference psychological research, we propose to delimit the philosophical approach to will from the psychological one, concluding that only the will as a psychic process can be educated, the qualities of will becoming character traits and, implicitly, personality traits, along the ontogenetic evolution of man.
