"So do not train your pupil to look down from the height of his glory upon the sufferings of the unfortunate, the labours of the wretched, and do not hope to teach him to pity them while he considers them as far removed from himself. Make him thoroughly aware of the fact that the fate of these unhappy persons may one day be his own, that his feet are standing on the edge of the abyss, into which he may be plunged at any moment by a thousand unexpected irresistible misfortunes. Teach him to put no trust in birth, health, or riches; show him all the changes of fortune; find him examples—there are only too many of them—in which men of higher rank than himself have sunk below the condition of these wretched ones. Above all do not teach him this, like his catechism, in cold blood; let him see and feel the calamities which overtake men; surprise and startle his imagination with the perils which lurk continually about a man's path; let him see the pitfalls all about him, and when he hears you speak of them, let him cling more closely to you for fear lest he should fall. "You will make him timid and cowardly," do you say? We shall see; let us make him kindly to begin with, that is what matters most."
