Fratelli Tutti §213

²¹³ The dignity of others is to be respected in all circumstances, not because that dignity is something we have invented or imagined, but because human beings possess an intrinsic worth superior to that of material objects and contingent situations. This requires that they be treated differently. That every human being possesses an inalienable dignity is a truth that corresponds to human nature apart from all cultural change. For this reason, human beings have the same inviolable dignity in every age of history and no one can consider himself or herself authorized by particular situations to deny this conviction or to act against it. The intellect can investigate the reality of things through reflection, experience and dialogue, and come to recognize in that reality, which transcends it, the basis of certain universal moral demands.
