Therefore, a moral act is not an act in obedience to an external law, human or divine. It is the inner law of our true being, of our essential or created nature, which demands that we actualize what follows from it. And an antimoral act is not the transgression of one or several precisely circumscribed commands, but an act that contradicts the self-realization of the person as a person and drives toward disintegration. It disrupts the centeredness of the person by giving predominance to partial trends, passions, desires, fears, and anxieties. The central control is weakened, often almost removed. And when this happens, and other partial trends also aspire to predominance, the self is split, and the conflicting trends make it their battlefield. The ‘will,’ in the sense of a self that acts from the centered totality of its being, is enslaved. Freedom is replaced by compulsion. Deliberation and decision, the hallmarks of freedom, become mere facades for overwhelming drives that predetermine the decision. The voice of man’s essential being is silenced, step by step; and his disintegrating self, his depersonalization, shows the nature of the antimoral act and, by contrast, the nature of the moral act.
