SOCRATES: Perhaps we may be wrong; if so, you in your wisdom should convince us that we are mistaken in preferring justice to injustice. THRASYMACHUS: And how am I to convince you, he said, if you are not already convinced by what I have just said; what more can I do for you? Would you have me put the proof bodily into your souls?
PlatoYou may be sure, dear Crito, that inaccurate language is not only in itself a mistake: it implants evil in men's souls.
PlatoThe true lover of learning then must his earliest youth, as far as in him lies, desire all truth.... He whose desires are drawn toward knowledge in every form will be absorbed in the pleasures of the soul, and will hardly feel bodily pleasures I mean, if he be a true philosopher and not a sham one ... Then how can he who has the magnificence of mind and is the spectator of all times and all existence, think much of human life He cannot. Or can such a one account death fearful No indeed.
