text: But my letter calls for its closing sentence. Hear and take to heart this useful and wholesome motto: "Cherish some man of high character, and keep him ever before your eyes, living as if he were watching you, and ordering all your actions as if he beheld them." Such, my dear Lucilius, is the counsel of Epicurus; he has quite properly given us a guardian and an attendant. We can get rid of most sins, if we have a witness who stands near us when we are likely to go wrong. The soul should have someone whom it can respect, – one by whose authority it may make even its inner shrine more hallowed. Happy is the man who can make others better, not merely when he is in their company, but even when he is in their thoughts! And happy also is he who can so revere a man as to calm and regulate himself by calling him to mind! One who can so revere another, will soon be himself worthy of reverence. Choose therefore a Cato; or, if Cato seems too severe a model, choose some Laelius, a gentler spirit. Choose a master whose life, conversation, and soul-expressing face have satisfied you; picture him always to yourself as your protector or your pattern. For we must indeed have someone according to whom we may regulate our characters; you can never straighten that which is crooked unless you use a ruler. Farewell.
