 It is difficult to give a precise evaluation of the influence of the School of Salamanca in the many fields to which it contributed. There are various ideological motives, apart from the general tendency to conceal one’s sources, why later authors did not mention these theologians. This was especially the case for philosophers, theologians, and legal theorists from the Protestant North with their aversion to Catholic thinkers, and especially Jesuits. Quarrels arose, for instance, as to whether the Dutch jurist Hugo Grotius (1583–1645) was the father of modern natural law and international law or whether he only copied and slightly altered the works of Suárez and other Spanish authors. Another pertinent issue is that Suárez was regarded as the representative of “the schools”, to which the founders of modern philosophy opposed their new philosophical systems, often denying their heritage. Some works by Spanish Scholastics therefore fell into oblivion. In recent years, however, the ideological barriers have vanished, and there is a growing interest in an open-minded discussion of the School’s achievements and impact.
