The Declaration of Independence was not only its first paragraph, that is the political manifesto of the right of revolution - the right of independence. The Declaration was also its second paragraph, that is the political manifesto of the Enlightenment constitutional project of the natural rights of man - the project which unified American and European Enlightenment in the Atlantic space with an Enlightenment Natural Rights of Man Talk. What happened to that project in the American constitutional process? To rewrite the history of the origins of the United States tracking down in the institutional and public debate that Enlightenment language, that constitutional project and that cultural heritage means to tell a passionate and glorious struggle that was lost. It means to talk - together with about the true and republican revolution, that of the right of independence - about a missed revolution - that of the natural rights of man. From a historiographical point of view, it means, in the American revolution, to break the continuity between the Declaration and the Constitution. Therefore, now those rights become fundamental in the current debate on the contemporary human rights - a debate in which their historical foundation is brought into question.
