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.
Consider that everything which happens, happens justly, and if thou observest carefully, thou wilt find it to be so. I do not say only with respect to the continuity of the series of things, but with respect to what is just, and as if it were done by one who assigns to each thing its value. Observe then as thou hast begun; and whatever thou doest, do it in conjunction with this, the being good, and in the sense in which a man is properly understood to be good. Keep to this in every action.
Consider, for example, the times of Vespasian. Thou wilt see all these things, people marrying, bringing up children, sick, dying, warring, feasting, trafficking, cultivating the ground, flattering, obstinately arrogant, suspecting, plotting, wishing for some to die, grumbling about the present, loving, heaping up treasure, desiring counsulship, kingly power. Well then, that life of these people no longer exists at all. Again, remove to the times of Trajan. Again, all is the same. Their life too is gone. In like manner view also the other epochs of time and of whole nations, and see how many after great efforts soon fell and were resolved into the elements. But chiefly thou shouldst think of those whom thou hast thyself known distracting themselves about idle things, neglecting to do what was in accordance with their proper constitution, and to hold firmly to this and to be content with it. And herein it is necessary to remember that the attention given to everything has its proper value and proportion. For thus thou wilt not be dissatisfied, if thou appliest thyself to smaller matters no further than is fit.
Look within. Let neither the peculiar quality of anything nor its value escape thee.
Neither is transpiration, as in plants, a thing to be valued, nor respiration, as in domesticated animals and wild beasts, nor the receiving of impressions by the appearances of things, nor being moved by desires as puppets by strings, nor assembling in herds, nor being nourished by food; for this is just like the act of separating and parting with the useless part of our food. What then is worth being valued? To be received with clapping of hands? No. Neither must we value the clapping of tongues, for the praise which comes from the many is a clapping of tongues. Suppose then that thou hast given up this worthless thing called fame, what remains that is worth valuing? This in my opinion, to move thyself and to restrain thyself in conformity to thy proper constitution, to which end both all employments and arts lead. For every art aims at this, that the thing which has been made should be adapted to the work for which it has been made; and both the vine-planter who looks after the vine, and the horse-breaker, and he who trains the dog, seek this end. But the education and the teaching of youth aim at something. In this then is the value of the education and the teaching. And if this is well, thou wilt not seek anything else. Wilt thou not cease to value many other things too? Then thou wilt be neither free, nor sufficient for thy own happiness, nor without passion. For of necessity thou must be envious, jealous, and suspicious of those who can take away those things, and plot against those who have that which is valued by thee. Of necessity a man must be altogether in a state of perturbation who wants any of these things; and besides, he must often find fault with the gods. But to reverence and honour thy own mind will make thee content with thyself, and in harmony with society, and in agreement with the gods, that is, praising all that they give and have ordered.
Different things delight different people. But it is my delight to keep the ruling faculty sound without turning away either from any man or from any of the things which happen to men, but looking at and receiving all with welcome eyes and using everything according to its value.
