These are some of the ideals that the founders of our institutions expressed, in part unconsciously, on that momentous day now passed by one hundred and forty years.  They knew that ideals do not maintain themselves.  They knew that they there declared a purpose which would be resisted by the forces, on land and sea, of the mightiest empire of the earth.  Without the resolution of the people of the Colonies to resort to arms, and without the guiding military genius of Washington, the Declaration of Independence would be naught in history but the vision of doctrinaires, a mockery of sounding brass and tinkling cymbal.  Let us never forget that it was that resolution and that genius which made it the vitalizing force of a great nation.  It takes service and sacrifice to maintain ideals.

But it is far more than the Declaration of Independence that brings us here to-day.  That was, indeed, a great document.  It was drawn up by Thomas Jefferson when he was at his best.  It was the product of men who seemed inspired.  No greater company ever assembled to interpret the voice of the people or direct the destinies of a nation.  The events of history may have added to it, but subtracted nothing.  Wisdom and experience have increased the admiration of it.  Time and criticism have not shaken it.  It stands with ordinance and law, charter and constitution, prophecy and revelation, whether we read them in the history of Babylon, the results of Runnymede, the Ten Commandments, or the Sermon on the Mount.  But, however worthy of our reverence and admiration, however preeminent, it was only one incident of a great forward movement of the human race, of which the American Revolution was itself only a larger incident.  It was not so much a struggle of the Colonies against the tyranny of bad government, as against wrong principles of government, and for self-government.  It was man realizing himself.  It was sovereignty from within which responded to the alarm of Paul Revere on that April night, and which went marching, gun in hand, against sovereignty from without, wherever it was found on earth.  It only paused at Concord, or Yorktown, then marched on to Paris, to London, to Moscow, to Pekin.  Against it the powers of privilege and the forces of despotism could not prevail.  Superstition and sham cannot stand before intelligence and reality.  The light that first broke over the thirteen Colonies lying along the Atlantic Coast was destined to illuminate the world.  It has been a struggle against the forces of darkness; victory has been and is still delayed in some quarters, but the result is not in doubt.  All the forces of the universe are ranged on the side of democracy.  It must prevail.
