A possession may be considered in the same nature as a part of anything; now a part is not only a part of something, but also is nothing else; so is a possession; therefore a master is only the master of the slave, but no part of him; but the slave is not only the slave of the master, but nothing else but that.
This fully explains what is the nature of a slave, and what are his capacities; for that being who by nature is nothing of himself, but totally another's, and is a man, is a slave by nature; and that man who is the property of another, is his mere chattel, though he continues a man; but a chattel is an instrument for use, separate from the body..
