" Are you so simple as to assume that the Big Surrender banished the concept of human slavery from the earth? What is the principle of slavery? Only the literal buying and selling of human flesh on the block? That was only an outside symbol. Real slavery is couched in the desire and the efforts of any man or community to live and advance their interests at the expense of the lives and interests of others. All of the outward signs come out of that. "
