Most of the Constitution's Framers knew, and many said, that slavery was wrong.

Our two most basic political ideals—liberty and equality—are, in their purest forms, incompatible. Complete liberty results in inequality, and mandatory equality leads to a loss of liberty.

Liberty and equality are in essence contradictory.

We know most of our forefathers, all of our main Founding Fathers, were against slavery, recognized the evils of it.

It is easy to demonstrate that "our Fathers, who framed this government under which we live," looked on Slavery as wrong, and so framed it and everything about it as to square with the idea that it was wrong, so far as the necessities arising from its existence permitted. In forming the Constitution they found the slave trade existing; capital invested in it; fields depending upon it for labor, and the whole system resting upon the importation of slave-labor. They therefore did not prohibit the slave trade at once, but they gave the power to prohibit it after twenty years. Why was this? What other foreign trade did they treat in that way? Would they have done this if they had not thought slavery wrong? Another thing was done by some of the same men who framed the Constitution, and afterwards adopted as their own act by the first Congress held under that Constitution, of which many of the framers were members; they prohibited the spread of Slavery into Territories. Thus the same men, the framers of the Constitution, cut off the supply and prohibited the spread of Slavery, and both acts show conclusively that they considered that the thing was wrong. If additional proof is wanting it can be found in the phraseology of the Constitution. When men are framing a supreme law and chart of government, to secure blessings and prosperity to untold generations yet to come, they use language as short and direct and plain as can be found, to express their meaning. In all matters but this of Slavery the framers of the Constitution used the very clearest, shortest, and most direct language. But the Constitution alludes to Slavery three times without mentioning it once! The language used becomes ambiguous, roundabout, and mystical. They speak of the "immigration of persons," and mean the importation of slaves, but do not say so. In establishing a basis of representation they say "all other persons," when they mean to say slaves — why did they not use the shortest phrase? In providing for the return of fugitives they say "persons held to service or labor." If they had said slaves it would have been plainer, and less liable to misconstruction. Why didn't they do it. We cannot doubt that it was done on purpose. Only one reason is possible, and that is supplied us by one of the framers of the Constitution — and it is not possible for man to conceive of any other — they expected and desired that the system would come to an end, and meant that when it did, the Constitution should not show that there ever had been a slave in this good free country of ours!

Now, I have upon all occasions declared as strongly as Judge Douglas against the disposition to interfere with the existing institution of slavery. You hear me read it from the same speech from which he takes garbled extracts for the purpose of proving upon me a disposition to interfere with the institution of slavery, and establish a perfect social and political equality between negroes and white people. Allow me while upon this subject briefly to present one other extract from a speech of mine, more than a year ago, at Springfield, in discussing this very same question, soon after Judge Douglas took his ground that negroes were not included in the Declaration of Independence: I think the authors of that notable instrument intended to include all men, but they did not mean to declare all men equal in all respects. They did not mean to say all men were equal in color, size, intellect, moral development, or social capacity. They defined with tolerable distinctness in what 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 they meant. They did not mean to assert the obvious untruth that all were then actually enjoying that equality, or 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, 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... That is the real issue. That is the issue that will continue in this country when these poor tongues of Judge Douglas and myself shall be silent. It is the eternal struggle between these two principles — right and wrong — throughout the world. They are the two principles that have stood face to face from the beginning of time; and will ever continue to struggle. The one is the common right of humanity, and the other the divine right of kings. It is the same principle in whatever shape it develops itself. It is the same spirit that says, "You toil and work and earn bread, and I'll eat it." No matter in what shape it comes, whether from the mouth of a king who seeks to bestride the people of his own nation and live by the fruit of their labor, or from one race of men as an apology for enslaving another race, it is the same tyrannical principle.

To the mind of the ancients, who knew something of such matters, liberty and prosperity seemed hardly compatible, yet modern liberalism wants them together.

If there be any fact in our history beyond dispute it is that Roger Sherman expressed the universal sentiment of our fathers when he said, 'The abolition of slavery seemed to be going on in the United States, and the good sense of the several States would probably by degrees complete it'. In that spirit the compromises of the Constitution were made. Had not slavery at that time deprecated itself as an evil, the Constitution could not have been formed. Could the future have been foreseen, it would not have been formed. But, reasoning from the light they had, it was fair to believe as they believed, that, when the slave-trade was prohibited, the system would wither away under the double curse of Morality and Law.

I do not mean to discuss the question how far slavery and farming are incompatible. Our opinions agree as to the evil, moral, political, and economical, of the former.

It may be said of Socialism, therefore, that its friends recommended it as increasing equality, while its foes resisted it as decreasing liberty….The compromise eventually made was one of the most interesting and even curious cases in history. It was decided to do everything that had ever been denounced in Socialism, and nothing that had ever been desired in it…we proceeded to prove that it was possible to sacrifice liberty without gaining equality….In short, people decided that it was impossible to achieve any of the good of Socialism, but they comforted themselves by achieving all the bad.

On the other hand, the free states carry on their government on the principle of the equality of men. We think slavery is morally wrong, and a direct violation of that principle. We all think it wrong. It is clearly proved, I think, by natural theology, apart from revelation. Every man, black, white or yellow, has a mouth to be fed and two hands with which to feed it, and that bread should be allowed to go to that mouth without controversy.

A society that aims for equality before liberty will end up with neither equality nor liberty.

Slavery is founded in the selfishness of man's nature, opposition to it in his love of justice. These principles are an eternal antagonism, and when brought into collision so fiercely as slavery extension brings them, shocks and throes and convulsions must ceaselessly follow.

The Declaration of Independence was formed by the representatives of American liberty from thirteen States of the confederacy; twelve of which were slaveholding communities. We need not discuss the way or the reason of their becoming slaveholding communities. It is sufficient for our purpose that all of them greatly deplored the evil and that they placed a provision in the Constitution which they supposed would gradually remove the disease by cutting off its source. This was the abolition of the slave trade. So general was conviction, the public determination, to abolish the African slave trade, that the provision which I have referred to as being placed in the Constitution, declared that it should not be abolished prior to the year 1808. A constitutional provision was necessary to prevent the people, through Congress, from putting a stop to the traffic immediately at the close of the war. Now, if slavery had been a good thing, would the Fathers of the Republic have taken a step calculated to diminish its beneficent influences among themselves, and snatch the boon wholly from their posterity? These communities, by their representatives in old Independence Hall, said to the whole world of men: "We hold these truths to be self evident: that all men are created equal; that they are endowed by their Creator with certain unalienable rights; that among these are life, liberty and the pursuit of happiness." This was their majestic interpretation of the economy of the Universe. This was their lofty, and wise, and noble understanding of the justice of the Creator to His creatures... Yes, gentlemen, to all His creatures, to the whole great family of man. In their enlightened belief, nothing stamped with the Divine image and likeness was sent into the world to be trodden on, and degraded, and imbruted by its fellows. They grasped not only the whole race of man then living, but they reached forward and seized upon the farthest posterity. They erected a beacon to guide their children and their children's children, and the countless myriads who should inhabit the earth in other ages. Wise statesmen as they were, they knew the tendency of prosperity to breed tyrants, and so they established these great self-evident truths, that when in the distant future some man, some faction, some interest, should set up the doctrine that none but rich men, or none but white men, were entitled to life, liberty and the pursuit of happiness, their posterity might look up again to the Declaration of Independence and take courage to renew the battle which their fathers began, so that truth, and justice, and mercy, and all the humane and Christian virtues might not be extinguished from the land; so that no man would hereafter dare to limit and circumscribe the great principles on which the temple of liberty was being built...
