Do the human rights of the law depend? What is the relationship between it and the demands of justice? The answer to what is really fundamental is not contained in the "Babel of languages" of constitutions, codes or sentences. It is necessary to take into consideration the general ideas and pluralism of the cultural, ethical, religious and political universes that characterize and complicate today's society. The ductile right is a peaceful and democratic proposal. Taking a journey through the European history of the rule of law of the nineteenth century to the constitutional state of our time, the book shows how legal norms can no longer be an expression of interests or the formulation of universal and immutable conceptions that someone can impose and others must abide. The principles of freedom and justice come into contact with the real cases of life and should guide the application of the law by judges, whose function is completely different from that of acting as mere spokesmen for the law.
