Sometimes I would make use of somewhat severe language, if I had any hope that by it he might be amended; though I would not irritate a hopelessly ungrateful man, for fear that I might turn him into an enemy. If we spare the ungrateful even the affront of reminding them of their conduct, we shall render them more backward in returning benefits; and although some might be cured of their evil ways, and be made into good men, if their consciences were stung by remorse, yet we shall allow them to perish for want of a word of warning, with which a father sometimes corrects his son, a wife brings back to herself an erring husband, or a man stimulates the wavering fidelity of his friend.
