CEVAP:

Complex reflections on natural law were prompted by a text of Isidore of Seville. According to Isidore, natural law includes the common possession of all things, the one liberty of all, and the acquisition of what is taken from air, land and sea; also, the restitution of a thing or money left for safekeeping. The “one liberty of all men” and “common possession of all things” belong to the “indications”. Since the indications do not impose strict obligations, human laws can for good reasons set them aside. To do so, they may even serve the recommended ideals, under some circumstances.
