12. Concerning things accidental to free will.

D. Because enough has been said concerning the accidents of natures, now you must speak about things accidental to free will. What is free will? M. The inviolable or spontaneous force of the soul, according to which diverse and contrary thoughts and deeds are effected. D. Is this power natural in us or spontaneous? There is a certain natural discernment of good and evil in us; but spontaneous is the movement in these things which, having already been discerned, must be carried out. Indeed, law instructs <the soul="">itself, but grace prepares it, helps it, strengthens it, and crowns it.
