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.

But this is very much the same as if thou shouldst be grieved because those who have lived before thee did not praise thee.
