“You will find that all the arguments in favor of king-craft were of this class; they always bestrode the necks of the people, not that they wanted to do it, but because the people were better off for being ridden. That is their argument, and this argument of the Judge is the same old serpent that says you work and I eat, you toil and I will enjoy the fruits of it.”

Speech in reply to Senator Stephen Douglas in the Lincoln-Douglas debates http://www.bartleby.com/251/1003.html of the 1858 campaign for the U.S. Senate, at Chicago, Illinois (10 July 1858)
1850s, Lincoln–Douglas debates (1858)
Context: Those arguments that are made, that the inferior race are to be treated with as much allowance as they are capable of enjoying; that as much is to be done for them as their condition will allow. What are these arguments? They are the arguments that kings have made for enslaving the people in all ages of the world. You will find that all the arguments in favor of king-craft were of this class; they always bestrode the necks of the people, not that they wanted to do it, but because the people were better off for being ridden. That is their argument, and this argument of the Judge is the same old serpent that says you work and I eat, you toil and I will enjoy the fruits of it. Turn in whatever way you will, whether it come from the mouth of a King, an excuse for enslaving the people of this country, or from the mouth of men of one race as a reason for enslaving the men of another race, it is all the same old serpent, and I hold if that course of argumentation that is made for the purpose of convincing the public mind that we should not care about this, should be granted, it does not stop with the negro. I should like to know if, taking this old Declaration of Independence, which declares that all men are equal upon principle, and making exceptions to it, where will it stop? If one man says it does not mean a negro, why not another say it does not mean some other man? If that declaration is not the truth, let us get the Statute book, in which we find it, and tear it out! Who is so bold as to do it? If it is not true let us tear it out! [Cries of "No, No."] Let us stick to it, then; let us stand firmly by it, then. It may be argued that there are certain conditions that make necessities and impose them upon us, and to the extent that a necessity is imposed upon a man, he must submit to it. I think that was the condition in which we found ourselves when we established this Government. We had slavery among us, we could not get our Constitution unless we permitted them to remain in slavery, we could not secure the good we did secure if we grasped for more; and having by necessity submitted to that much, it does not destroy the principle that is the charter of our liberties. Let that charter stand as our standard.
