How can you prove whether at this moment we are sleeping, and all our thoughts are a dream; or whether we are awake, and talking to one another in the waking state?
PlatoThere is yet something remaining for the dead, and some far better thing for the good than for the evil.
PlatoHe who is gracious to his lover under the impression that he is rich, and is disappointed of his gains because he turns out to be poor, is disgraced all the same: for he has done his best to show that he would give himself up to any one's "uses base" for the sake of money; but this is not honourable.
