Opus legis scriptum in cordibus suis: o problema do conhecimento e prática moral no jusnaturalismo de Tomás de Aquino.

Abstract

This work is a historical and conceptual study, located in the field of moral epistemology and medieval philosophy, which investigates the problem of moral knowledge and practice within the aquinian jusnaturalism. The jusnaturalism, when claims that there are innate, universal and natural moral notions, partially replies to the problem on origin of moral knowledge and brings up others questions, for instance, what is the nexus between moral knowledge and practice and what is the relevance of theoretical rationality to the moral practice. We present that the aquinian jusnaturalism considers the speculative rationality as capital to the free and efctive practice of the moral good.
