Ethical normativity and personal responsibility [1/4]
Duty
Moral duty may become concrete by distinguishing what is morally good or bad and identifying why.
However, the science of positivist morality reduces itself to considering only what it is and how.
Rather, from the experience of morality, ethics seeks duty, by norming, performing and structuring it with originality and creativity, to achieve in the best way the good, up to the gift.
Aristotle noted that, while the rules of implementation pursue the good of action, moral norms seek the good of the agent.
While Kant distinguished morality from legality and put them in opposition, St. Thomas Aquinas had already emphasized that law is an element of the moral order, which in turn is based on the order of being.
