Every evil is a sickness of soul, but virtue offers the cause of its health.
Do not measure your loss by itself; if you do, it will seem intolerable; but if you will take all human affairs into account you will find that some comfort is to be derived from them.
It is impious to say that evil has its origin from God, because naught contrary is produced by the contrary. Life does not generate death, nor is darkness the beginning of light, nor is disease the maker of health, but in the changes of conditions there are transitions from one condition to the contrary.
Many a man curses the rain that falls upon his head, and knows not that it brings abundance to drive away the hunger.
