"If slavery is right, all words, acts, laws, and constitutions against it, are themselves wrong, and should be silenced, and swept away."
"With public sentiment, nothing can fail; without it nothing can succeed. Consequently he who moulds public sentiment, goes deeper than he who enacts statutes or pronounces decisions. He makes statutes and decisions possible or impossible to be executed."

Abraham Lincoln was the 16th president of the United States, serving from 1861 until his assassination in 1865. He led the United States through the American Civil War, defeating the Confederate States and playing a major role in the abolition of slavery.
"If slavery is right, all words, acts, laws, and constitutions against it, are themselves wrong, and should be silenced, and swept away."
"Neither let us be slandered from our duty by false accusations against us, nor frightened from it by menaces of destruction to the Government nor of dungeons to ourselves. Let us have faith that right makes might, and in that faith, let us, to the end, dare to do our duty as we understand it."
"We know, Southern men declare that their slaves are better off than hired laborers amongst us. How little they know, whereof they speak! There is no permanent class of hired laborers amongst us. Twentyfive years ago, I was a hired laborer. The hired laborer of yesterday, labors on his own account to-day; and will hire others to labor for him to-morrow. Advancement — improvement in condition — is the order of things in a society of equals. As Labor is the common burthen of our race, so the effort of some to shift their share of the burthen on to the shoulders of others, is the great, durable, curse of the race. Originally a curse for transgression upon the whole race, when, as by slavery, it is concentrated on a part only, it becomes the double-refined curse of God upon his creatures."
"Wherever slavery is, it has been first introduced without law. The oldest laws we find concerning it, are not laws introducing it; but regulating it, as an already existing thing."
"The negative principle that no law is free law, is not much known except among lawyers."
"An inspection of the Constitution will show that the right of property in a slave is not "distinctly and expressly affirmed" in it."
