Liberalismo político y razón pública: Una aproximación a John Rawls desde la teoría de la Ley Natural

The paper explores John Rawls´s idea of public reason, as reflected in Political Liberalism and The Idea of Public Reason Revisited. In Rawls’s later works, public reason acquires fundamental significance as a criterion by which the principles to be assumed from the outset in a theory of political justice may be determined. The starting-point for Rawls´s theory -the idea of citizens as free and equal reveals- that this abstraction falls short of an authentic conception of human beings as social by nature. A brief study of key issues concerning marriage and the family shows the difficulties that underlie this question. The paper also offers a concise overview of some of the principles of Natural Law Theory. In this context, a theory of political liberalism and justice might be upheld by drawing natural law and public reason into close correlation, thus safeguarding the substantive human goods necessary in society
