Die Transformation des Konzepts des „Gerechten Kriegs“ (Bellum iustum) in der Geschichte der Philosophie: Von Thomas von Aquin bis zur Schule von Salamanca

The article is first dealing with the very specific arguments of the doctrine of »Just War« in the »Summa theologiae« II-II, q. 40 of Thomas Aquinas. It refers second to the process of a massive transformation by which authors of the so-called »School of Salamanca« in early modern times like Vitoria, Cano or Suárez modified the original »Just War«-theory of Aquinas. And it reflects finally upon the relevance and meaning of these transformations for the systematic discussion of classical »Just-War«-theory today, that means in a time after Kant’s »theory of peace« on the one hand and the constitution of the UN-Charter on the other by which the legitimacy of war is limited just to cases of a self-defense of states.
