Must I undertake to prove that the slave is a man? That point is conceded already. Nobody doubts it. The slave-holders themselves acknowledge it in the enactment of laws for their government. They acknowledge it when they punish disobedience on the part of the slave. There are seventy-two crimes in the State of Virginia, which, if committed by a black man (no matter how ignorant he be), subject him to the punishment of death; while only two of these same crimes will subject a white man to like punishment. 
And there he killed the claim by some that slave holders thought slaves were not human. If slaves were not considered human then why enact laws which they expected to be followed? Do we enact laws to punish animals who disobey the rules of their own will?
