Positive law, or ius positum, refers to legal rules established by human authority to regulate societies, distinguishing it from natural law, which originates in inherent moral or divine principles. It includes statutory and judicial law, reflecting the provisional character of legal systems. Thinkers like Wilhelm Roscher emphasized its genesis beyond formal legislation, while Joseph Story underscored its function in reconciling moral, natural, and social demands.
Virgil M. Harris highlighted its development through shared human experience, and Johann Gottlieb Fichte demonstrated its practical application in particular cases. Positive law thus emerges as a dynamic structure, shaped by human action to balance order, justice, and shifting societal values.
