Man is the only government-making animal in the world. His right to a participation in the production and operation of government is an inference from his nature, as direct and self-evident as is his right to acquire property or education. It is no less a crime against the manhood of a man, to declare that he shall not share in the making and directing of the government under which he lives, than to say that he shall not acquire property and education. The fundamental and unanswerable argument in favor of the enfranchisement of the negro is found in the undisputed fact of his manhood. He is a man, and by every fact and argument by which any man can sustain his right to vote, the negro can sustain his right equally.
--Frederick Douglass, An Appeal to Congress for Impartial Suffrage (1867)
