These are times in which a Genious would wish to live. It is not in the still calm of life, or the repose of a pacific station, that great characters are formed. Would Cicero have shone so distinguished an orater, if he had not been roused, kindled and enflamed by the Tyranny of Catiline, Millo, Verres and Mark Anthony. The Habits of a vigorous mind are formed in contending with difficulties. All History will convince you of this, and that wisdom and penetration are the fruits of experience, not the Lessons of retirement and leisure. Great necessities call out great virtues. When a mind is raised, and animated by scenes that engage the Heart, then those qualities which would otherways lay dormant, wake into Life, and form the Character of the Hero and the Statesman.
