When two friends are in the mood to chat, we have to go about it in a gentler and more dialectical way. By 'more dialectical,' I mean not only that we give real responses, but that we base our responses solely on what the interlocutor admits that he himself knows.
Everything desires not like but unlike: for example, the dry desires the moist, the cold the hot, the bitter the sweet, the sharp the blunt, the void the full, the full the void, and so of all other things; for the opposite is the food of the opposite, whereas like receives like receives nothing from like.
Those wretches who never have experienced the sweets of wisdom and virtue, but spend all their time in revels and debauches, sink downward day after day, and make their whole life one continued series of errors.
In things which we know, everyone will trust us ... and we may do as we please, and no one will like to interfere with us; and we are free, and masters of others; and these things will be really ours, for we shall turn them to our good.
I would have you imagine, then, that there exists in the mind of man a block of wax... and that we remember and know what is imprinted as long as the image lasts; but when the image is effaced, or cannot be taken, then we forget or do not know.
And the quality of good judgement is clearly a form of knowledge and skill, as it is because of knowledge and not because of ignorance that we judge well.
Great is the issue at stake, greater than appears, whether a man is to be good or bad. And what will any one be profited if, under the influence of money or power, he neglect justice and virtue?
