to his enemies
in time of sickness?

The physician.

Or when they are on a voyage, amid the perils of the sea?

The pilot.

And in what sort of actions or with a view to what result is the just
man most able to do harm to his enemy and good to his friend?

In going to war against the one and in making alliances with the other.

But when a man is well, my dear Polemarchus, there is no need of a
physician?

No.

And he who is not on a voyage has no need of a pilot?

No.

Then in time of peace justice will be of no use?

I am very far from thinking so.

You think that justice may be of use in peace as well as in war?

Yes.

Like husbandry for the acquisition of corn?

Yes.

Or like shoemaking for the acquisition of shoes,--that is what you mean?

Yes.

And what similar use or power of acquisition has justice in time of
peace?

In contracts, Socrates, justice is of use.

And by contracts you mean partnerships?

Exactly.

But is the just man or the skilful player a more useful and better
partner at a game of draughts?

The skilful player.

And in the laying of bricks and stones is the just man a more useful or
better partner than the builder?

Quite the reverse.

Then in what sort of partnership is the just man a better partner than
the harp-player, as in playing the harp the harp-player is certainly a
better partner than the just man?

In a money partnership.

Yes, Polemarchus, but surely not in the use of money; for you do not
want a just man to be your counsellor in the purchase or sale of a
horse; a man who is knowing about horses would be better for that, would
he not?

Certainly.

And when you want to buy a ship, the shipwright or the pilot would be
better?

True.

Then what is that joint use of silver or gold in which the just man is
to be preferred?

When you want a deposit to be kept safely.

You mean when money is not wanted, but allowed to lie?

Precisely.

That is to say, justice is useful when money is useless?

That is the inference.

And when you want to keep a pruning-hook safe, then justice is useful to
the individual and to the state; but when you want to use it, then the
art of the vine-dresser?

Clearly.

And when you want to keep a shield or a lyre, and not to use them, you
would say that justice is useful; but when you want to use them, then
the art of the soldier or of the musician?

Certainly.

And so of all other things;--justice is use
