O philosophy, you leader of life.
The whole glory of virtue resides in activity.
Nothing troubles you for which you do not yearn.
The man who commands efficiently must have obeyed others in the past, and the man who obeys dutifully is worthy of someday being a commander.
No phase of life, whether public or private, can be free from duty.
Scurrility has no object in view but incivility; if it is uttered from feelings of petulance, it is mere abuse; if it is spoken in a joking manner, it may be considered raillery.
