To the aids which have been mentioned let this one still be added:- Make for thyself a definition or description of the thing which is presented to thee, so as to see distinctly what kind of a thing it is in its substance, in its nudity, in its complete entirety, and tell thyself its proper name, and the names of the things of which it has been compounded, and into which it will be resolved. For nothing is so productive of elevation of mind as to be able to examine methodically and truly every object which is presented to thee in life, and always to look at things so as to see at the same time what kind of universe this is, and what kind of use everything performs in it, and what value everything has with reference to the whole, and what with reference to man, who is a citizen of the highest city, of which all other cities are like families; what each thing is, and of what it is composed, and how long it is the nature of this thing to endure which now makes an impression on me, and what virtue I have need of with respect to it, such as gentleness, manliness, truth, fidelity, simplicity, contentment, and the rest. Wherefore, on every occasion a man should say: this comes from God; and this is according to the apportionment and spinning of the thread of destiny, and such-like coincidence and chance; and this is from one of the same stock, and a kinsman and partner, one who knows not however what is according to his nature. But I know; for this reason I behave towards him according to the natural law of fellowship with benevolence and justice. At the same time however in things indifferent I attempt to ascertain the value of each.
Take care that thou art not made into a Caesar, that thou art not dyed with this dye; for such things happen. Keep thyself then simple, good, pure, serious, free from affectation, a friend of justice, a worshipper of the gods, kind, affectionate, strenuous in all proper acts. Strive to continue to be such as philosophy wished to make thee. Reverence the gods, and help men. Short is life. There is only one fruit of this terrene life, a pious disposition and social acts. Do everything as a disciple of Antoninus. Remember his constancy in every act which was conformable to reason, and his evenness in all things, and his piety, and the serenity of his countenance, and his sweetness, and his disregard of empty fame, and his efforts to understand things; and how he would never let anything pass without having first most carefully examined it and clearly understood it; and how he bore with those who blamed him unjustly without blaming them in return; how he did nothing in a hurry; and how he listened not to calumnies, and how exact an examiner of manners and actions he was; and not given to reproach people, nor timid, nor suspicious, nor a sophist; and with how little he was satisfied, such as lodging, bed, dress, food, servants; and how laborious and patient; and how he was able on account of his sparing diet to hold out to the evening, not even requiring to relieve himself by any evacuations except at the usual hour; and his firmness and uniformity in his friendships; and how he tolerated freedom of speech in those who opposed his opinions; and the pleasure that he had when any man showed him anything better; and how religious he was without superstition. Imitate all this that thou mayest have as good a conscience, when thy last hour comes, as he had.
Everywhere and at all times it is in thy power piously to acquiesce in thy present condition, and to behave justly to those who are about thee, and to exert thy skill upon thy present thoughts, that nothing shall steal into them without being well examined.
A spider is proud when it has caught a fly, and another when he has caught a poor hare, and another when he has taken a little fish in a net, and another when he has taken wild boars, and another when he has taken bears, and another when he has taken Sarmatians. Are not these robbers, if thou examinest their opinions?
Accustom thyself as much as possible on the occasion of anything being done by any person to inquire with thyself, For what object is this man doing this? But begin with thyself, and examine thyself first.
