Abraham Lincoln

"Fourscore and seven years ago our fathers brought forth on this continent a new nation, conceived in liberty and dedicated to the proposition that all men are created equal." (Lincoln's Gettysburg Address on November 19, 1863)

"Whenever I hear any one arguing for slavery I feel a strong impulse to see it tried on him personally." (The Collected Works of Abraham Lincoln edited by Roy P. Basler, Volume VIII, "Speech to One Hundred Fortieth Indiana Regiment" (March 17, 1865), p. 361)
