To recover the intrinsic relationship between the concepts of good, norm and virtue which constitute the truth and moral meaning of human action is the most important challenge of contemporary ethics. The aim of this paper is to compare, from this perspective, Cicero's concept of law in his dialogue De legibus with the concept of law as held by procedural ethics.

In this article an attempt is made to bring out the presuppositions of the first formulation of ethical realism held by Antonio Millán-Puelles in his recently published work, La libre afirmación de nuestro ser. Una fundamentacíon de la ética realista. These presuppositions show that the central problem in moral philosophy, known as the "Is-Ought" question, is dealt with in a very positive way by pointing out the intrinsic relation that there is between human nature and human freedom.
