A sound discretion is not so much indicated by never making a mistake as by never repeating it.
- Bovee, Christian Nestell

Discretion is the perfection of reason, and a guide to us in all the duties of life.
- La Bruyere, Jean

He who knows does not speak; He who speaks does not know. He who is truthful is not showy; He who is showy is not truthful. He who is virtuous does not dispute; He who disputes is not virtuous. He who is learned is not wise; He who is wise is not learned. Therefore the sage does not display his own merits.
- Lao-Tzu
