From Calvin Coolidge’s 1926 4th of July address:
If no one is to be accounted as born into a superior station, if there is to be no ruling class, and if all possess rights which can neither be bartered away nor taken from them by any earthly power, it follows as a matter of course that the practical authority of the Government has to rest on the consent of the governed. While these principles were not altogether new in political action, and were very far from new in political speculation, they had never been assembled before and declared in such a combination. But remarkable as this may be, it is not the chief distinction of the Declaration of Independence. The importance of political speculation is not to be underestimated, as I shall presently disclose. Until the idea is developed and the plan made there can be no action.
It was the fact that our Declaration of Independence containing these immortal truths was the political action of a duly authorized and constituted representative public body in its sovereign capacity, supported by the force of general opinion and by the armies of Washington already in the field, which makes it the most important civil document in the world. It was not only the principles declared, but the fact that therewith a new nation was born which was to be founded upon those principles and which from that time forth in its development has actually maintained those principles, that makes this pronouncement an incomparable event in the history of government. It was an assertion that a people had arisen determined to make every necessary sacrifice for the support of these truths and by their practical application bring the War of Independence to a successful conclusion and adopt the Constitution of the United States with all that it has meant to civilization.
The idea that the people have a right to choose their own rulers was not new in political history. It was the foundation of every popular attempt to depose an undesirable king. This right was set out with a good deal of detail by the Dutch when as early as July 26, 1581, they declared their independence of Philip of Spain. In their long struggle with the Stuarts the British people asserted the same principles, which finally culminated in the Bill of Rights deposing the last of that house and placing William and Mary on the throne. In each of these cases sovereignty through divine right was displaced by sovereignty through the consent of the people. Running through the same documents, though expressed in different terms, is the clear inference of inalienable rights. But we should search these charters in vain for an assertion of the doctrine of equality. This principle had not before appeared as an official political declaration of any nation. It was profoundly revolutionary. It is one of the corner stones of American institutions.
