Happy Fourth of July from NAS! Today we celebrate the day when, over two centuries ago, during a hot summer in Pennsylvania, the American dream of self-government came alive.
In the midst of making history, John Adams found time to write his wife Abigail about the happenings in Philadelphia:
July 3, 1776. Philadelphia.
Yesterday the greatest Question was decided, which ever was debated in America, and a greater perhaps, never was or will be decided among Men. A Resolution was passed without one dissenting Colony “that these united Colonies, are, and of right ought to be free and independent States, and as such, they have, and of Right ought to have full Power to make War, conclude Peace, establish Commerce, and to do all the other Acts and Things, which other States may rightfully do.” You will see in a few days a Declaration setting forth the Causes, which have impell’d Us to this mighty Revolution, and the Reasons which will justify it, in the Sight of God and Man. A Plan of Confederation will be taken up in a few days.
He wrote her in another letter that same day:
Time has been given for the whole People, maturely to consider the great Question of Independence and to ripen their judgments, dissipate their Fears, and allure their Hopes, by discussing it in News Papers and Pamphletts, by debating it, in Assemblies, Conventions, Committees of Safety and Inspection, in Town and County Meetings, as well as in private Conversations, so that the whole People in every Colony of the 13, have now adopted it, as their own Act.—This will cement the Union, and avoid those Heats and perhaps Convulsions which might have been occasioned, by such a Declaration Six Months ago.
But the Day is past. The Second Day of July 1776, will be the most memorable Epocha, in the History of America.
I am apt to believe that it will be celebrated, by succeeding Generations, as the great anniversary Festival. It ought to be commemorated, as the Day of Deliverance by solemn Acts of Devotion to God Almighty. It ought to be solemnized with Pomp and Parade, with Shews, Games, Sports, Guns, Bells, Bonfires and Illuminations from one End of this Continent to the other from this Time forward forever more.
You will think me transported with Enthusiasm but I am not.—I am well aware of the Toil and Blood and Treasure, that it will cost Us to maintain this Declaration, and support and defend these States.—Yet through all the Gloom I can see the Rays of ravishing Light and Glory. I can see that the End is more than worth all the Means. And that Posterity will tryumph in that Days Transaction, even altho We should rue it, which I trust in God We shall not.
Years later, just before his death, Thomas Jefferson wrote to Roger C. Weightman, forced to decline an invitation to be present at the fiftieth anniversary of America's birth because of his failing health:
June 24, 1826. Monticello.
The kind invitation I receive from you, on the part of the citizens of the city of Washington, to be present with them at their celebration of the fiftieth anniversary of American Independence, as one of the surviving signers of an instrument pregnant with our own, and the fate of the world, is most flattering to myself, and heightened by the honorable accompaniment proposed for the comfort of such a journey. It adds sensibly to the sufferings of sickness, to be deprived by it of a personal participation in the rejoicings of that day. But acquiescence is a duty, under circumstances not placed among those we are permitted to control. I should, indeed, with peculiar delight, have met and exchanged there congratulations personally with the small band, the remnant of that host of worthies, who joined with us on that day, in the bold and doubtful election we were to make for our country, between submission or the sword; and to have enjoyed with them the consolatory fact, that our fellow citizens, after half a century of experience and prosperity, continue to approve the choice we made. May it be to the world, what I believe it will be, (to some parts sooner, to others later, but finally to all,) the signal of arousing men to burst the chains under which monkish ignorance and superstition had persuaded them to bind themselves, and to assume the blessings and security of self-government. That form which we have substituted, restores the free right to the unbounded exercise of reason and freedom of opinion. All eyes are opened, or opening, to the rights of man. The general spread of the light of science has already laid open to every view the palpable truth, that the mass of mankind has not been born with saddles on their backs, nor a favored few booted and spurred, ready to ride them legitimately, by the grace of God. These are grounds of hope for others. For ourselves, let the annual return of this day forever refresh our recollections of these rights, and an undiminished devotion to them.
Both men passed away that same year and on the same day—July 4, 1826. Both lived to see the establishment of a regime unlike any other in history.
May we honor their memory as we celebrate our freedom this Independence Day.
