MENO: Quite right; and that is just what I am saying about virtue--that
there are other virtues as well as justice.

SOCRATES: What are they? tell me the names of them, as I would tell you
the names of the other figures if you asked me.

MENO: Courage and temperance and wisdom and magnanimity are virtues; and
there are many others.

SOCRATES: Yes, Meno; and again we are in the same case: in searching
after one virtue we have found many, though not in the same way as before;
but we have been unable to find the common virtue which runs through them
all.

MENO: Why, Socrates, even now I am not able to follow you in the attempt
to get at one common notion of virtue as of other things.

SOCRATES: No wonder; but I will try to get nearer if I can, for you know
that all things have a common notion. Suppose now that some one asked you
the question which I asked before: Meno, he would say, what is figure?
And if you answered 'roundness,' he would reply to you, in my way of
speaking, by asking whether you would say that roundness is 'figure' or 'a
figure;' and you would answer 'a figure.'

MENO: Certainly.

SOCRATES: And for this reason--that there are other figures?

MENO: Yes.
