O Cleinias, are those who learn the wise or the ignorant?
He answered that those who learned were the wise.
Euthydemus proceeded: There are some whom you would call teachers, are there not?
The boy assented.
And they are the teachers of those who learn — the grammar-master and the lyre master used to teach you and other boys; and you were the learners?
And when you were learners you did not as yet know the things which you were learning?
No, he said.
And were you wise then?
No, indeed, he said.
But if you were not wise you were unlearned?
You then, learning what you did not know, were unlearned when you were learning?
The youth nodded assent.
Then the unlearned learn, and not the wise, Cleinias, as you imagine.
– Plato, Euthydemus
