Socrates: …[I]t would be [ridiculous] when I tried in earnest to persuade you by putting together a speech in praise of the donkey, labelling it a horse and saying that the beast would be an invaluable acquisition both at home and on active service, useful to fight from and capable too of carrying baggage, and good for many other purposes.
Phaedrus: Then it would be thoroughly ridiculous.
Socrates: Well then, isn’t it better to be ridiculous and a friend than to be clever and an enemy? […] So when an expert in rhetoric who is ignorant of good and bad finds a city in the same condition and tries to persuade it, by making his eulogy not about a miserable donkey as if it were a horse but about what is bad as if it were good, and — having applied himself to what the masses think — actually persuades the city to do something bad instead of good, what sort of harvest do you think rhetoric reaps after that from the seed it sowed?
