"Slavery originated in force, by the stronger against the weaker party, and not by natural right; that it is maintained and upheld by oppression and wrong, and against the law of nature. This usurped ownership in man is not that kind of property which is recognized by the general consent of mankind. The advanced state of civilized society does not recognize the right of one man to own another man against his will. The inalienable right of life, liberty, and the pursuit of happiness, is conceded to all. The right of every man to himself, to enjoy the fruits of his own ingenuity and industry, are among the natural rights of every person made in the image of God."
