Crítica a la teoría del conocimiento práctico de Grisez & Finnis

The present work is divided into three parts. In the first part, I briefly explain the ontology of natural law from the perspective of the «New Natural Law Theory» (NNLT) and I contrast this with what I consider to be Aquinas’s own view. In the second part, I deal with knowledge of natural law according to the NNLT and according to St. Thomas. Here, I attend closely to Aquinas’s view of the nature of practical knowledge in order to highlight the differentiating features that separate it from the NNLT view. In the last chapter, I deal with the NNLT’s marginalization of the virtues in knowledge of the natural law, and conclude that Grisez and Finnis’s theory of moral knowledge is closer to Kant than to Saint Thomas.
