16. 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 horsebreaker, 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 honor 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. 17. Above, below, all around are the movements of the elements. But the motion of virtue is in none of these: it is something more divine, and advancing by a way hardly observed, it goes happily on its road. 18. How strangely men act! They will not praise those who are living at the same time and living with themselves; but to be themselves praised by posterity, by those whom they have never seen or ever will see, this they set much value on. But this is very much the same as if thou shouldst be grieved because those who have lived before thee did not praise thee. 19. If a thing is difficult to be accomplished by thyself, do not think that it is impossible for man: but if anything is possible for man and conformable to his nature, think that this can be attained by thyself too.
