Kant’s autonomism qualifies man as a legislator, a source of law and justice, forgetting that man is a creature dependent on God and that reason must correctly decipher natural laws; conscience, as responsible for actions, must respect them for justice towards the Creator.
Disordered passions prefer passing goods and harden to the sting of the conscience. Laws divide responsibilities and limit risks but they may give occasion to sordid licenses as consciences are less affected by a reduced obligation of accountability.
Such increased autonomy is detached from the ethical and religious order and endangers the souls, who should be aware of their moral responsibility to engage in service. Autonomy must respect the intrinsic goodness in things and that corresponds to the mandate to dominate the world in the service of man, with creative relations between action and welfare according to the immanent natural laws. It is incompatible with Catholic teachings to deny a specific and determined, universal and permanent moral content in the Word of God; the denial disperses the sense of the conscience, circumvents logic and congruence, falling back on less responsibility and greater rights for autonomy and free will, aimed at freedom and pleasure only.
The reduction of the person to a set of experiences does not explain the fundamentals of responsibility in free action.
