Golden Sayings of Epictetus
Context: Canst thou judge men?... then make us imitators of thyself, as Socrates did. Do this, do not do that, else will I cast thee into prison; this is not governing men like reasonable creatures. Say rather, As God hath ordained, so do; else thou wilt suffer chastisement and loss. Askest thou what loss? None other than this: To have left undone what thou shouldst have done: to have lost the faithfulness, the reverence, the modesty that is in thee! Greater loss than this seek not to find! (91).
