Socrates
Socrates. Then when the orator who does not know what good and evil are undertakes to persuade a state which is equally ignorant, not by praising the shadow of an ass under the name of a horse, but by praising evil under the name of good, and having studied the opinions of the multitude persuades them to do evil instead of good, what harvest do you suppose his oratory will reap thereafter from the seed he has sown?
Phaedrus
Phaedrus. No very good harvest.
Socrates
Socrates. Well, do you think we have reproached the art of speaking too harshly? Perhaps she might say: Why do you talk such nonsense, you strange men? I do not compel anyone to learn to speak without knowing the truth, but if my advice is of any value, he learns that first and then acquires me. So what I claim is this, that without my help the knowledge of the truth does not give the art of persuasion.
Phaedrus
Phaedrus. And will she be right in saying this?

Socrates
Socrates. Yes, if the arguments that are coming against her testify that she is an art. For I seem, as it were, to hear some arguments approaching and protesting that she is lying and is not an art, but a craft devoid of art. A real art of speaking, says the Laconian, which does not seize hold of truth, does not exist and never will.
Phaedrus
Phaedrus. We have need of these arguments, Socrates. Bring them here and examine their words and their meaning.
