This article addresses the issue of the pre-legal nature of the Juridical and its stratification in the social and legal level. Also, it contrasts the theory of the will and the theory of the declaration, and refers to the controversy between Emilio Betti and Giuseppe Stolfi about the dispute over the language. The idea of monism is developed in the theory of the Juridical Act quoting Santi Romano and Hans Kelsen, as well as its tensions with dualism. Finally, it takes Juridical Act as historiographical category, and its relationship to the problems of technological society and closes with the gap between private autonomy and Juridical Act. / El presente artículo aborda la cuestión de la naturaleza prejurídica del negocio jurídico, así como su estratificación en el plano social y jurídico.

In this dissertation I am analysing certain aspects of labour, especially the ones that are of significant interest to moral philosophy within the church and its catholic doctrine. In the same time I identify the foundation for freedom and dignity of labouring human being that are being degraded especially in the present time economisation process. Further, I outline the issues associated with the changes within the division of labour from industrial revolution to present day and in the same time I present issues connected with labouring human being vs. human capital. Because freedom is the foundation of humanity I also describe issues connected with human rights in the context of universal and natural law. In this way I analyse Universal Declaration of Human Rights and its defence in an intercultural environment. Lastly, besides those theoretical concepts, I evaluate an Amnesty International CR project called "Business That is Worth It" which aims at supporting companies to a responsible management of employees rights protection especially in developing countries.
