Natural law assumes that institution and value are joint and interdependent, in a rational, knowable and achievable way.
This is seen by positivism as a meddling on morality, but the truth about good exceeds the experience of value and justifies norms, so that the nature of human action concretizes the principles of good and goodness.
Some phenomenologists, including Scheler, believe that the values are sensitive, but elusive to reason.
However, each act is fair in reference to natural rights of its own and its neighbor, for what it is and is worth; so the nature of the person emerges as the sake of action in relation to others.
Moral sensitivity discovers in the acts the personal moment that realizes one’s own humanity and participates in the realization of the world and the community.
The person can become a true participant of the Eternal Law, when the natural right is elevated from mental and spiritual necessity to the freedom to assume one's own duties.
