SOCRATES: And what art makes each individual agree with himself?

ALCIBIADES: The same.

SOCRATES: And what art makes each of us agree with himself about the comparative length of the span and of the cubit? Does not the art of measure?

ALCIBIADES: Yes.

SOCRATES: Individuals are agreed with one another about this; and states, equally?

ALCIBIADES: Yes.

SOCRATES: And the same holds of the balance?

ALCIBIADES: True.

SOCRATES: But what is the other agreement of which you speak, and about what? what art can give that agreement? And does that which gives it to the state give it also to the individual, so as to make him consistent with himself and with another?

ALCIBIADES: I should suppose so.
