Adam Smith Retrospective VIIFrom Part VI, Section III, of Adam Smith's Theory of Moral Sentiments . . .
To act according to the dictates of prudence, of justice, and proper beneficence, seems to have no great merit where there is no temptation to do otherwise. But to act with cool deliberation in the midst of the greatest dangers and difficulties; to observe religiously the sacred rules of justice in spite both of the greatest interests which might tempt, and the greatest injuries which might provoke us to violate them; never to suffer the benevolence of our temper to be damped or discouraged by the malignity and ingratitude of the individuals towards whom it may have been exercised; is the character of the most exalted wisdom and virtue. Self-command is not only itself a great virtue, but from it all the other virtues seem to derive their principal lustre.
