Böhm-Bawerk, pp. 29 ff. — Charles Dumoulin’s (Molinäus, 1500–1566) theory of interest was taken up by other jurists, including Hugo Grotius and, in particular, the French Calvinist Claude de Saumaise (Salmasius, 1588–1653), who, as a professor at Leiden, advocated for the productivity of money in several writings. Beginning with his treatise “De usuris” (1638), he sparked the scholarly debate over the prohibition of interest. This work and the related polemical writings bear witness to the controversy surrounding the new doctrines. - II. Wissenbach (1607–1665) became known primarily for his polemical writings directed against Salmasius. - III. Letter to a friend opposing Salmasius’s views. - Untrimmed. - 1.
