"These ideas of the essential dignity of the individual human being of the fundamental equality of all men, and of certain inalienable rights to freedom, justice, and a fair opportunity represent to the American people the essential meaning of the nation's early struggle for independence. In the clarity and intellectual boldness of the Enlightenment period these tenets were written into the Declaration of Independence, the Preamble of the Constitution, the Bill of Rights and into the constitutions of the several states. The ideals of the American Creed have thus become the highest law of the land. The Supreme Court pays its reverence to these general principles when it declares what is constitutional and what is not. They have been elaborated upon by all national leaders, thinkers and statesmen. America has had, throughout its history, a continuous discussion of the principles and implications of democracy, a discussion which, in every epoch, measured by any standard, remained high, not only quantitatively but qualitatively. The flow of learned treatises and popular tracts on the subject has not ebbed, nor is it likely to do so. In all wars, including the present one, the American Creed has been the ideological foundation of national morale."
