Aristotle's Account of Slavery

Aristotle says women need men to tell them what to do, since they are by nature unable to regulate their own affairs properly. He argues that some people are 'natural slaves' and it is not only permissible to enslave such people but actually the right thing to do. A natural slave is in an even worse condition than a free woman when it comes to conducting his own life. It is good for the slave to be owned, just as it is good for a woman to be dominated by her husband or father.
