Epictetus on Mind

"The appearance of things to the mind is the standard of every action to man."

"Keep death and exile daily before thine eyes, with all else that men deem terrible, but more especially Death. Then wilt thou never think a mean thought, nor covet anything beyond measure. ."

"One who knows not who he is and to what end he was born; what kind of world this is and with whom he is associated therein; one who cannot distinguish Good and Evil, Beauty and Foulness,... Truth and Falsehood, will never follow Reason in shaping his desires and impulses and repulsions, nor yet in assent, denial, or suspension of judgment; but will in one word go about deaf and blind, thinking himself to be somewhat, when he is in truth of no account. Is there anything new in all this? Is not this ignorance the cause of all the mistakes and mischances of men since the human race began?..." ."

"The true Cynic must know that he is sent as a Messenger from God to men, to show unto them that as touching good and evil they are in error; looking for those where they are not to be found, nor ever bethinking themselves where they are. And like Diogenes when brought before Philip after the battle of Chæronea, the Cynic must remember that he is a Spy. For a Spy he really is—to bring back word what things are on Man's side, and what against him. And when he has diligently observed all, he must come back with a true report, not terrified into announcing them to be foes that are no foes, nor otherwise perturbed or confounded by the things of sense. ."
