The name "School of Salamanca" refers to a group of theologians and natural law philosophers who taught in the University of Salamanca, following the inspiration of the great Thomist Francisco de Vitoria. It turns out that the Scholastics were not simply medieval, but began in the 13th century and expanded through the 16th and 17th centuries; and they developed some original theories about economics and international law.Why should a few men mainly interested in theology and ethics apply themselves in analyzing (...) issues so far from their worries? The answer leads us to a revision of the morality rules, due to the new problems in business ethics. Thus, for example, the appearance of inflation made them have doubts about the merchant's morality. In order to solve this and other problems, they began to analyze the new and suspicious economic activity. As a result of their observations about ethical issues they discovered some advanced theories for the history of economic thought, such as the early formulation of the quantity theory of money.
