It was not because it was proposed to establish a new nation, but because it was proposed to establish a nation on new principles, that July 4, 1776, has come to be regarded as one of the greatest days in history. Great ideas do not burst upon the world unannounced. They are reached by a gradual development over a length of time usually proportionate to their importance. This is especially true of the principles laid down in the Declaration of Independence. Three very definite propositions were set out in its preamble regarding the nature of mankind and therefore of government. These were the doctrine that all men are created equal, that they are endowed with certain inalienable rights , and that therefore the source of the just powers of government must be derived from the consent of the governed.
It is not so much then for the purpose of undertaking to proclaim new theories and principles that this annual celebration is maintained, but rather to reaffirm and reestablish those old theories and principles which time and the unerring logic of events have demonstrated to be sound. Amid all the clash of conflicting interests, amid all the welter of partisan politics, every American can turn for solace and consolation to the Declaration of independence and the Constitution of the United States with the assurance and confidence that those two great charters of freedom and justice remain firm and unshaken. Whatever perils appear, whatever dangers threaten, the Nation remains secure in the knowledge that the ultimate application of the law of the land will provide an adequate defense and protection.
