Elevate your Independence Day by reading this moving 1852 oration by Frederick Douglass in its entirety. There is so much to appreciate in this speech, it is difficult to select excerpts. But here is one passage I particularly like:

But, your fathers, who had not adopted the fashionable idea of this day, of the infallibility of government, and the absolute character of its acts, presumed to differ from the home government in respect to the wisdom and the justice of some of those burdens and restraints. They went so far in their excitement as to pronounce the measures of government unjust, unreasonable, and oppressive, and altogether such as ought not to be quietly submitted to. I scarcely need say, fellow-citizens, that my opinion of those measures fully accords with that of your fathers.

Or this:

Must I undertake to prove that the slave is a man? That point is conceded already. . . . It is admitted in the fact that Southern statute books are covered with enactments forbidding, under severe fines and penalties, the teaching of the slave to read or to write. When you can point to any such laws, in reference to the beasts of the field, then I may consent to argue the manhood of the slave. When the dogs in your streets, when the fowls of the air, when the cattle on your hills, when the fish of the sea, and the reptiles that crawl, shall be unable to distinguish the slave from a brute, there will I argue with you that the slave is a man!

Or this:

What, to the American slave, is your 4th of July? I answer: a day that reveals to him, more than all other days in the year, the gross injustice and cruelty to which he is the constant victim. To him, your celebration is a sham; your boasted liberty, an unholy license; your national greatness, swelling vanity; your sounds of rejoicing are empty and heartless; your denunciations of tyrants, brass fronted impudence; your shouts of liberty and equality, hollow mockery; your prayers and hymns, your sermons and thanksgivings, with all your religious parade, and solemnity, are, to him, mere bombast, fraud, deception, impiety, and hypocrisy — a thin veil to cover up crimes which would disgrace a nation of savages. There is not a nation on the earth guilty of practices, more shocking and bloody, than are the people of these United States, at this very hour. Go where you may, search where you will, roam through all the monarchies and despotisms of the old world, travel through South America, search out every abuse, and when you have found the last, lay your facts by the side of the everyday practices of this nation, and you will say with me, that, for revolting barbarity and shameless hypocrisy, America reigns without a rival.

But later he turns to the Constitution:

But it is answered in reply to all this, that precisely what I have now denounced is, in fact, guaranteed and sanctioned by the Constitution of the United States; that the right to hold and to hunt slaves is a part of that Constitution framed by the illustrious Fathers of this Republic.
Then, I dare to affirm, notwithstanding all I have said before, your fathers stooped, basely stooped

"To palter with us in a double sense:
And keep the word of promise to the ear,
But break it to the heart."

And instead of being the honest men I have before declared them to be, they were the veriest imposters that ever practised on mankind. This is the inevitable conclusion, and from it there is no escape. But I differ from those who charge this baseness on the framers of the Constitution of the United States. It is a slander upon their memory, at least, so I believe. There is not time now to argue the constitutional question at length — nor have I the ability to discuss it as it ought to be discussed. The subject has been handled with masterly power by Lysander Spooner, Esq., by William Goodell, by Samuel E. Sewall, Esq., and last, though not least, by Gerritt Smith, Esq. These gentlemen have, as I think, fully and clearly vindicated the Constitution from any design to support slavery for an hour.

"[L]et me ask, if it be not somewhat singular that, if the Constitution were intended to be, by its framers and adopters, a slave-holding instrument, why neither slavery, slaveholding, nor slave can anywhere be found in it."

Fellow-citizens! there is no matter in respect to which, the people of the North have allowed themselves to be so ruinously imposed upon, as that of the pro-slavery character of the Constitution. In that instrument I hold there is neither warrant, license, nor sanction of the hateful thing; but, interpreted as it ought to be interpreted, the Constitution is a GLORIOUS LIBERTY DOCUMENT. Read its preamble, consider its purposes. Is slavery among them? Is it at the gateway? or is it in the temple? It is neither. While I do not intend to argue this question on the present occasion, let me ask, if it be not somewhat singular that, if the Constitution were intended to be, by its framers and adopters, a slave-holding instrument, why neither slavery, slaveholding, nor slave can anywhere be found in it. What would be thought of an instrument, drawn up, legally drawn up, for the purpose of entitling the city of Rochester to a tract of land, in which no mention of land was made? Now, there are certain rules of interpretation, for the proper understanding of all legal instruments. These rules are well established. They are plain, common-sense rules, such as you and I, and all of us, can understand and apply, without having passed years in the study of law. I scout the idea that the question of the constitutionality or unconstitutionality of slavery is not a question for the people. I hold that every American citizen has a right to form an opinion of the constitution, and to propagate that opinion, and to use all honorable means to make his opinion the prevailing one. Without this right, the liberty of an American citizen would be as insecure as that of a Frenchman. . . .

Now, take the constitution according to its plain reading, and I defy the presentation of a single pro-slavery clause in it. On the other hand it will be found to contain principles and purposes, entirely hostile to the existence of slavery.

I have detained my audience entirely too long already. At some future period I will gladly avail myself of an opportunity to give this subject a full and fair discussion. [Which he does in his 1860 Speech in Glasgow that borrows much from the writers he cites above but with substantial additional argumentation of his own. If someone has a good link, please post it in comments.]

He then concludes with what could have been a paean to the Internet and other liberating technologies:

Allow me to say, in conclusion, notwithstanding the dark picture I have this day presented of the state of the nation, I do not despair of this country. There are forces in operation, which must inevitably work The downfall of slavery. "The arm of the Lord is not shortened," and the doom of slavery is certain. I, therefore, leave off where I began, with hope. While drawing encouragement from the Declaration of Independence, the great principles it contains, and the genius of American Institutions, my spirit is also cheered by the obvious tendencies of the age. Nations do not now stand in the same relation to each other that they did ages ago. No nation can now shut itself up from the surrounding world, and trot round in the same old path of its fathers without interference. The time was when such could be done. Long established customs of hurtful character could formerly fence themselves in, and do their evil work with social impunity. Knowledge was then confined and enjoyed by the privileged few, and the multitude walked on in mental darkness. But a change has now come over the affairs of mankind. Walled cities and empires have become unfashionable. The arm of commerce has borne away the gates of the strong city. Intelligence is penetrating the darkest corners of the globe. It makes its pathway over and under the sea, as well as on the earth. Wind, steam, and lightning are its chartered agents. Oceans no longer divide, but link nations together. From Boston to London is now a holiday excursion. Space is comparatively annihilated. Thoughts expressed on one side of the Atlantic are, distinctly heard on the other. The far off and almost fabulous Pacific rolls in grandeur at our feet. The Celestial Empire, the mystery of ages, is being solved. The fiat of the Almighty, "Let there be Light," has not yet spent its force. No abuse, no outrage whether in taste, sport or avarice, can now hide itself from the all-pervading light. The iron shoe, and crippled foot of China must be seen, in contrast with nature. Africa must rise and put on her yet unwoven garment. "Ethiopia shall stretch out her hand unto God." In the fervent aspirations of William Lloyd Garrison, I say, and let every heart join in saying it:
God speed the year of jubilee
The wide world o'er!
When from their galling chains set free,
Th' oppress'd shall vilely bend the knee,
And wear the yoke of tyranny
Like brutes no more.
That year will come, and freedom's reign,
To man his plundered rights again
Restore. . . .
