“I think the authors of that notable instrument intended to include all men, but they did not intend to declare all men equal in all respects. They did not mean to say all were equal in color, size, intellect, moral developments, or social capacity. They defined with tolerable distinctness, in what respects they did consider all men created equal; equal in "certain inalienable rights, among which are life, liberty, and the pursuit of happiness."”

Those are undeniable truths.

1850s, The Present Aspect of the Slavery Question (1859)
Context: Such is the present aspect of the slavery question. For myself, I believe that the faith in which the government was founded still survives. I believe that the spirit of despotism which now says to the country, 'I will rule or ruin', will hear the imperial voice of the conscience of the American people, recognizing that justice and prosperity walk hand in hand, saying, 'You will do neither'. I believe that God did not hide this continent through all time as the spot whereon a nation should be planted upon the only principle that can render a nation as permanent as the race, to suffer the experiment to fail within a century. I believe these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain inalienable rights, that among these are life, liberty, and the pursuit of happiness. Do you believe it? If aye, let us go into the battle, and God speed the right.

2000s, Is Diversity Good? (2003)
Context: To allow slavery to be introduced into free territories, where it had not hitherto existed, was, Abraham Lincoln held, a very bad thing. His opponent, Stephen A. Douglas, held that it was a sacred right, belonging to the people of each territory, to decide for themselves whether or not to have slavery among their domestic institutions. According to Douglas, Lincoln wanted to destroy the diversity upon which the union had subsisted, by insisting that all the states ought to be free. But for Douglas himself, the principle of 'popular sovereignty' did not admit of exceptions. There was to be no diversity, no deviation from the right of the people to decide. For Lincoln the wrongness of slavery meant that no one, and no people, had the right to decide in its favor. For Lincoln, the principle of human equality, "that all men are created equal", did not admit exceptions.

1860s
Context: You know that in his Charleston speech, an extract from which he has read, he declared that the negro belongs to an inferior race; is physically inferior to the white man, and should always be kept in an inferior position. I will now read to you what he said at Chicago on that point. In concluding his speech at that place, he remarked, 'My friends, I have detained you about as long as I desire to do, and I have only to say let us discard all this quibbling about this man and the other man-this race and that race, and the other race being inferior, and therefore they must be placed in an inferior position, discarding our standard that we have left us. Let us discard all these things, and unite as one people throughout this land until we shall once more stand up declaring that all men are created equal'. Thus you see, that when addressing the Chicago Abolitionists he declared that all distinctions of race must be discarded and blotted out, because the negro stood on an equal footing with the white man; that if one man said the Declaration of Independence did not mean a negro when it declared all men created equal, that another man would say that it did not mean another man; and hence we ought to discard all difference between the negro race and all other races, and declare them all created equal.

1920s, Equal Rights (1920)
Context: July 4, 1776 was the historic day on which the representatives of three millions of people vocalized Concord, and Lexington, and Bunker Hill, which gave notice to the world that they proposed to establish an independent nation on the theory that all men are created equal, that they are endowed by their creator with certain inalienable rights, that among these are life, liberty, and the pursuit of happiness. The wonder and glory of the American people is not the ringing Declaration of that day, but the action then already begun, and in the process of being carried out, in spite of every obstacle that war could interpose, making the theory of freedom and equality a reality.

That is the true genius of America—a faith in simple dreams, an insistence on small miracles.
