“If men were equal in America, all these Poles and English and Czechs and blacks, then they were equal everywhere, and there was really no such thing as foreigner; there were only free men and slaves.”

Mary Barton, ch. 37.

1850s, Speech on the Dred Scott Decision (1857)
Context: 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." This they said, and this meant. They did not mean to assert the obvious untruth, that all were then actually enjoying that equality, nor yet, that they were about to confer it immediately upon them. In fact they had no power to confer such a boon. They meant simply to declare the right, so that the enforcement of it might follow as fast as circumstances should permit. They meant to set up a standard maxim for free society, which should be familiar to all, and revered by all; constantly looked to, constantly labored for, and even though never perfectly attained, constantly approximated, and thereby constantly spreading and deepening its influence, and augmenting the happiness and value of life to all people of all colors everywhere. The assertion that "all men are created equal" was of no practical use in effecting our separation from Great Britain; and it was placed in the Declaration, nor for that, but for future use. Its authors meant it to be, thank God, it is now proving itself, a stumbling block to those who in after times might seek to turn a free people back into the hateful paths of despotism. They knew the proneness of prosperity to breed tyrants, and they meant when such should re-appear in this fair land and commence their vocation they should find left for them at least one hard nut to crack. I have now briefly expressed my view of the meaning and objects of that part of the Declaration of Independence which declares that "all men are created equal".

Context: There is a further and deeper reason why colonization failed and why all subsequent attempts to return Americans of African descent to Africa, even those originating solely within the black community, have failed. The reason is that the overwhelming majority of these Americans regard their destiny to be in the United States. They were, after all, sold into slavery originally by black tribesmen, who captured them in order to sell them, and who slaughtered the ones they did not sell. No resent of slavery, however profound, engendered any love of a mythical African homeland. To have asked them to return to Africa was not unlike asking American Jews whose parents or grandparents fled czarist or Stalinist tyranny to return to Russia. However involuntary their emigration from Africa, American Negroes, whether free or slave, have always seen America itself as the promised land. Both Christianity and the Declaration of Independence embodied promise to all men. They saw no better or equal hope anywhere else, and certainly not in Africa. The truth is that the slaves, ignorant and illiterate as they may have seemed, were far from unintelligent. The Bible that they heard about, even if they were not allowed to read it, contained stories that convinced them that the same God that had freed the children of Israel would free them. Jefferson Davis might have thought this to be mere credulity. Yet it certainly compared favorably with his own absurd reading of the story of Noah.

Context: The Emergency which Islam had imposed after its advent in India and which had caused resentment among Hindus for a long time, now stood fully sanctioned by the Hindu elite. All religions were equal. But Islam was more equal.
