justice, is convicted out of his own mouth.

Alcibiades rejoins, that the Athenians debate not about what is just, but
about what is expedient; and he asserts that the two principles of justice
and expediency are opposed. Socrates, by a series of questions, compels
him to admit that the just and the expedient coincide. Alcibiades is thus
reduced to the humiliating conclusion that he knows nothing of politics,
even if, as he says, they are concerned with the expedient.

However, he is no worse than other Athenian statesmen; and he will not need
training, for others are as ignorant as he is. He is reminded that he has
to contend, not only with his own countrymen, but with their enemies--with
the Spartan kings and with the great king of Persia; and he can only attain
this higher aim of ambition by the assistance of Socrates. Not that
Socrates himself professes to have attained the truth, but the questions
which he asks bring others to a knowledge of themselves, and this is the
first step in the practice of virtue.

good in what? Alcibiades replies--'Good in transacting business.' But
what business? 'The business of the most intelligent men at Athens.' The
cobbler is intelligent in shoemaking, and is therefore good in that; he is
not intelligent, and therefore not good, in weaving. Is he good in the
sense which Alcibiades means, who is also bad? 'I mean,' replies
Alcibiades, 'the man who is able to command in the city.' But to command
what--horses or men? and if men, under what circumstances? 'I mean to say,
that he is able to command men living in social and political relations.'
And what is their aim? 'The better preservation of the city.' But when is
a city better? 'When there is unanimity, such as exists between husband
and wife.' Then, when husbands and wives perform their own special duties,
