Abstract

This article is about the radical unity of natural law, and shows that, according to the thinking of Saint Thomas, the plurality of moral precepts can be adequately understood only in its light. In other words, any precept of natural law is a precept because it participates in the first principle. It follows that a division of the precepts into primary, secondary and tertiary precepts does not correspond to a schematic classification. The distinction of primary, secondary and tertiary precepts of natural law is a relative distinction.
