and remember what you and Gorgias say that virtue is.

MENO: Will you have one definition of them all?

SOCRATES: That is what I am seeking.

MENO: If you want to have one definition of them all, I know not what to
say, but that virtue is the power of governing mankind.

SOCRATES: And does this definition of virtue include all virtue? Is
virtue the same in a child and in a slave, Meno? Can the child govern his
father, or the slave his master; and would he who governed be any longer a
slave?

MENO: I think not, Socrates.

SOCRATES: No, indeed; there would be small reason in that. Yet once more,
fair friend; according to you, virtue is 'the power of governing;' but do
you not add 'justly and not unjustly'?

MENO: Yes, Socrates; I agree there; for justice is virtue.

SOCRATES: Would you say 'virtue,' Meno, or 'a virtue'?

MENO: What do you mean?

SOCRATES: I mean as I might say about anything; that a round, for example,
is 'a figure' and not simply 'figure,' and I should adopt this mode of
speaking, because there are other figures.
