And does this line,
Yes.
And have we here four equal lines
We have.
Now consider how large this space
I do not understand.
Has not each of the inside lines cut off half of each of these four spaces?
Yes.
And how many spaces of that size are there in this part?
Four.
And how many in this
Two.
And four is how many times two?
Twice.
And how many feet is this space
Eight feet.
From what line do we get this figure?
From this.
From the line drawn corner-wise across the (our-foot figure?
Yes.
The professors call it the diagonal: so if the diagonal is its name, then according to you, Meno’s boy, the double space is the square of the diagonal.
Yes, certainly it is, Socrates.
What do you think, Meno? Was there any opinion that he did not give as an answer of his own thought?
No, they were all his own.
But you see, he did not know, as we were saying a while since.
That is true.
Yet he had in him these opinions, had he not?
Yes.
So that he who does not know about any matters, whatever they be, may have true opinions on such matters, about which he knows nothing?
Apparently.
And at this moment those opinions have just been stirred up in him, like a dream; but if he were repeatedly asked these same questions in a variety of forms, you know he will have in the end as exact an understanding
So it seems.
Without anyone having taught him, and only through questions put to him, he will understand, recovering the knowledge out of himself?
Yes.
And is not this recovery of knowledge, in himself and by himself, recollection?
Certainly.
And must he not have either once acquired or always had the knowledge he now has?
Yes.
Now if he always had it, he was always in a state of knowing; and if he acquired it all some time, he could not have acquired it in this life.
Well, I know that no one has ever taught him.
And has he these opinions, or has he not?
He must have them, Socrates, evidently.
