The concern for ensuring adequate protection of certain human values ​​has led to a struggle for rights and recognition, security and implementation. The phenomenon called expansion or proliferation, following the end of World War II, the demand picture has generated new individual and collective rights and has managed to capture many of them both in international conventions and treaties and domestic laws. Talk of rights has become commonplace, but the way we talk about the rights depends heavily on the historical role they have had some theories and concepts advocated by jurists and philosophers. Today coexist different conceptions of rights that largely determine the ways in which we talk about them and the communication barriers between different groups of speakers (lawyers, politicians, internationalists, NGOs, etc.).

The purpose of this book is to analyze some important aspects of this language, specifically conceptual problems as the notions of individual rights, moral rights, social rights and collective rights, among others, relevant in the language of rights. It is argued that the conceptual and theoretical problems have important practical implications when trying to protect and ensure the rights, so to worry about such matters is more than an intellectual luxury. This paper presents a unified view of rights that accounts for how both are used in the legal context as in the field of moral and political fights.
