The relationship between law and morality is a topic which receives special importance and attention, especially in "e;liberal democracies"e; in which the law is supposed to regulate highly pluralized and fragmented societies. Under conditions of plurality of values, many social forces and legal theories require a certain kind of neutrality from the legal system, a means of compatibility of the many "e;world views"e; and "e;moral systems"e; that are present within the same social space. Such a conciliating commitment sounds particularly relevant in times of the doctrinal ubiquity of ideas such as "e;peace based on human rights"e;. This was the title of the 28th World Congress of the IVR in Lisbon, with the special workshop "e;Law and Morals"e; on which this e-book is based. It is divided into four parts: "e;Law and Practical Reason"e;, "e;Conceptual Approaches on Law and Morals"e;, "e;Legal versus Moral Normativity"e;, and "e;Morals and Legal Positivism"e;.
