True knowledge is when one knows the limitations of one's knowledge.
If you don't know how to serve men, why worry about serving the gods?
Good people strengthen themselves ceaselessly
At fifteen my mind was directed to study, and at thirty I knew where to stand.
The more people know, the more they forgive.
Wisdom delights in water; love delights in hills. Wisdom is stirring; love is quiet. Wisdom is merry; love grows old.
