It is posited [Alexander of Hales, William of Auxerre] that sin is the privation of the good in which it is, because it harms it, as is argued from Augustine City of God 12.6 [n.13]; in another way [Thomas Aquinas] that sin is the privation of a supernatural good, namely grace; or in a third way [Bonaventure] that it is the corruption of the acquired habits to which evil acts are virtually repugnant, as a habit generated from acts formally bad is repugnant formally to habits of virtue.
