TOMÁS DE AQUINO Y LA LEY NATURAL INTERPRETACIONES CRUZADAS DE SUMMA THEOLOGIAE I-II, 94, 2

Abstract

The central text of western natural law is that of the  Summa Theologiae , of Thomas Aquinas I-II, q. 94. a.2, in which the Aquinate refers to three types of realities: human nature, natural inclinations and human goods. In general, one of these types has been prioritized when studying the ways of knowing Natural Law, throwing other authors into the corner of errors, inaccuracies and even evil. This work supports the hypothesis that the study of nature, inclinations and goods as sources of natural regulations is not necessarily exclusive, and that a careful and dispassionate analysis leads to the conclusion that these are diverse but complementary ways, and that a study from the synergy of these sources of knowledge leads to richer and more explanatory solutions than those achieved by those who see them as exclusive alternatives.
