SOCRATES: Let us put the matter thus:—Suppose that I persuaded you to buy a horse and go to the wars. Neither of us knew what a horse was like, but I knew that you believed a horse to be of tame animals the one which has the longest ears.
PHAEDRUS: That would be ridiculous.
SOCRATES: There is something more ridiculous coming:—Suppose, further, that in sober earnest I, having persuaded you of this, went and composed a speech in honour of an ass, whom I entitled a horse beginning: 'A noble animal and a most useful possession, especially in war, and you may get on his back and fight, and he will carry baggage or anything.'
PHAEDRUS: How ridiculous!
SOCRATES: Ridiculous! Yes; but is not even a ridiculous friend better than a cunning enemy?
PHAEDRUS: Certainly.
SOCRATES: And when the orator instead of putting an ass in the place of a horse, puts good for evil, being himself as ignorant of their true nature as the city on which he imposes is ignorant; and having studied the notions of the multitude, falsely persuades them not about 'the shadow of an ass,' which he confounds with a horse, but about good which he confounds with evil,—what will be the harvest which rhetoric will be likely to gather after the sowing of that seed?
PHAEDRUS: The reverse of good.
SOCRATES: But perhaps rhetoric has been getting too roughly handled by us, and she might answer: What amazing nonsense you are talking! As if I forced any man to learn to speak in ignorance of the truth! Whatever my advice may be worth, I should have told him to arrive at the truth first, and then come to me. At the same time I boldly assert that mere knowledge of the truth will not give you the art of persuasion.
PHAEDRUS: There is reason in the lady's defence of herself.
