euthydemus   

The wise, replied Cleinias.
Then after all the wise are the learners and not the unlearned; and
your last answer to Euthydemus was wrong.
Then once more the admirers of the two heroes, in an ecstasy at their
wisdom, gave vent to another peal of laughter, while the rest of us
were silent and amazed. Euthydemus, observing this, determined to
persevere with the youth; and in order to heighten the effect went on
asking another similar question, which might be compared to the double
turn of an expert dancer. Do those, said he, who learn, learn what
they know, or what they do not know?
Again Dionysodorus whispered to me: That, Socrates, is just another of
the same sort.
Good heavens, I said; and your last question was so good!
Like all our other questions, Socrates, he replied-inevitable.
I see the reason, I said, why you are in such reputation among your
disciples.
Meanwhile Cleinias had answered Euthydemus that those who learned
learn what they do not know; and he put him through a series of
questions the same as before.
Do you not know letters?
He assented.
All letters?
Yes.
But when the teacher dictates to you, does he not dictate letters?
To this also he assented.
Then if you know all letters, he dictates that which you know?
This again was admitted by him.
Then, said the other, you do not learn that which he dictates; but he
only who does not know letters learns?
Nay, said Cleinias; but I do learn.
Then, said he, you learn what you know, if you know all the letters?
He admitted that.
Then, he said, you were wrong in your answer.
The word was hardly out of his mouth when Dionysodorus took up the
argument, like a ball which he caught, and had another throw at the
youth. Cleinias, he said, Euthydemus is deceiving you. For tell me
now, is not learning acquiring knowledge of that which one learns?
Cleinias assented.
And knowing is having knowledge at the time?
He agreed.
And not knowing is not having knowledge at the time?
He admitted that.
And are those who acquire those who have or have not a thing?
Those who have not.
And have you not admitted that those who do not know are of the number
of those who have not?
He nodded assent.
Then those who learn are of the class of those who acquire, and not of
those who have?
He agreed.
Then, Cleinias, he said, those who do not know learn, and not those
who know.
Euthydemus was proceeding to give the youth a third fall; but I knew
that he was in deep water, and therefore, as I wanted to give him a
respite lest he should be disheartened, I said to him consolingly: You
must not be surprised, Cleinias, at the singularity of their mode of
speech: this I say because you may not understand what the two
strangers are doing with you; they are only initiating you after the
manner of the Corybantes in the mysteries; and this answers to the
enthronement, which, if you have ever been initiated, is, as you will
know, accompanied by dancing and sport; and now they are just prancing
and dancing about you, and will next proceed to initiate you; imagine
then that you have gone through the first part of the sophistical
ritual, which, as Prodicus says, begins with initiation into the
