摘要：The point of the relationship (or not) between law and morality has been studied for long time into Theory and Philosophy of Law. According to these fields, there are several questions: are law and morality strongly connected? Justice, as a moral value, has relations with law? The law enforcement and its utility require the morality of Law? In this article, we analyze such issues, demonstrating the necessary connection between law and morality. The starting point is Kelsen's theory, who denies the moral influence Law. Then, we study how the separation between law and morality is one of the pure requirements of Kelsen’s theory. We finally note the lack of separation between these two dimensions analyzing what Radbruch, Dworkin and Alexy explain concerning the connection between law and morality.
