About virtue
Morality is the flower of truth.
[France] Hugo
Virtue can be divided into two types: one is the virtue of wisdom, and the other is the virtue of behavior. The former comes from learning, and the latter comes from practice.
[Ancient Greece] Aristotle
Without public morality, society ceases to exist; without personal virtue, individual existence loses value.
[UK] Russell
The true measure of a man's character is what he does when he knows no one will notice.
[France] Montesquieu
Virtue is like a battlefield. We must live a virtuous life and constantly fight with ourselves.
[France] Rousseau
Virtue has many preachers but few martyrs.
[France] Helvetius
For the practice of morality, the best audience is people's own conscience.
