"We must become masters of our own actions and attitudes. To let another person determine whether we will be rude or gracious, elated or depressed is to give control of ourselves. The only true possession is self possession."

The right of a nation to determine its own form of government does not include the right to establish a slave society (that is, to legalize the enslavement of some men by others). There is no such thing as "the right to enslave." A nation can do it, just as a man can become a criminal- but neither can do it by right.
