Be slow to fall into friendship; but when thou art in, continue firm and constant.

In order that the mind should see light instead of darkness, so the entire soul must be turned away from this changing world, until its eye can learn to contemplate reality and that supreme splendor which we have called the good. Hence there may well be an art whose aim would be to effect this very thing.

Whenever any one informs us that he has found a man who knows all the arts, and all things else that anybody knows, and every single thing with a higher degree of accuracy than any other man - whoever tells us this, I think that we can only imagine him to be a simple creature who is likely to have been deceived by some wizard or actor whom he met, and whom he thought all-knowing, because he himself was unable to analyse the nature of knowledge and ignorance and imitation.

A painter will paint a cobbler, carpenter, or any other artist, though he knows nothing of their arts; and, if he is a good artist, he may deceive children or simple persons, when he shows them his picture of a carpenter from a distance, and they will fancy that they are looking at a real carpenter.
