ALCIBIADES: None.

SOCRATES: I do not suppose that you ever saw or heard of men quarrelling
over the principles of health and disease to such an extent as to go to war
and kill one another for the sake of them?

ALCIBIADES: No indeed.

SOCRATES: But of the quarrels about justice and injustice, even if you
have never seen them, you have certainly heard from many people, including
Homer; for you have heard of the Iliad and Odyssey?

ALCIBIADES: To be sure, Socrates.

SOCRATES: A difference of just and unjust is the argument of those poems?

ALCIBIADES: True.

SOCRATES: Which difference caused all the wars and deaths of Trojans and
Achaeans, and the deaths of the suitors of Penelope in their quarrel with
Odysseus.

ALCIBIADES: Very true.

SOCRATES: And when the Athenians and Lacedaemonians and Boeotians fell at
Tanagra, and afterwards in the battle of Coronea, at which your father
Cleinias met his end, the question was one of justice--this was the sole
cause of the battles, and of their deaths.

ALCIBIADES: Very true.
