The present essay intends to investigate the possibilities of a constructive dialogue concerning Human Rights. The starting point of this task is the comprehension of the fragmentation process of the contemporary global legal system. The most important mark of this process is the consolidation of the self-contained regimes, which deviates from general norms of International Law, in a way that threatens its unity. Such regimes seek to regulate disciplines of particularly high degrees of technical expertise. It demands legal lawyers to develop mechanisms capable of understanding the peculiarities of international relations. In such a context, the search for an element capable of granting certain unity amidst fragmentation becomes paramount.  Key words: international law, fragmentation and unity, public policy.
