The Science of Right-Immanual Kant- 1790

A practical jurisconsult (jurisperitus), or a professional lawyer, is one who is skilled in the knowledge of positive external laws, and who can apply them to cases that may occur in experience. Such practical knowledge of positive right, and law, may be regarded as belonging to jurisprudence (jurisprudentia) in the original sense of the term. But the theoretical knowledge of right and law in principle, as distinguished from positive laws and empirical cases, belongs to the pure science of right (jurisscientia).
