They will be for adding sofas, and tables, and other furniture; also dainties, and perfumes, and incense, and courtesans, and cakes, all these not of one sort only, but in every variety; we must go beyond the necessaries of which I was at first speaking, such as houses, and clothes, and shoes: the arts of the painter and the embroiderer will have to be set in motion, and gold and ivory and all sorts of materials must be procured.
True, he said.
Then we must enlarge our borders; for the original healthy State is no longer sufficient.

Now will the city have to fill and swell with a multitude of callings which are not required by any natural want; such as the whole tribe of hunters and actors, of whom one large class have to do with forms and colours; another will be the votaries of music--poets and their attendant train of rhapsodists, players, dancers, contractors; also makers of divers kinds of articles, including women's dresses.

And we shall want more servants.

Will not tutors be also in request, and nurses wet and dry, tirewomen and barbers, as well as confectioners and cooks; and swineherds, too, who were not needed and therefore had no place in the former edition of our State, but are needed now?
They must not be forgotten: and there will be animals of many other kinds, if people eat them.
Certainly.
And living in this way we shall have much greater need of physicians than before?
Much greater.
And the country which was enough to support the original inhabitants will be too small now, and not enough?
Quite true.
Then a slice of our neighbours' land will be wanted by us for pasture and tillage, and they will want a slice of ours, if, like ourselves, they exceed the limit of necessity, and give themselves up to the unlimited accumulation of wealth?
That, Socrates, will be inevitable.
And so we shall go to war, Glaucon.

Shall we not?
Most certainly, he replied.
Then without determining as yet whether war does good or harm, thus much we may affirm, that now we have discovered war to be derived from causes which are also the causes of almost all the evils in States, private as well as public.
Undoubtedly.
And our State must once more enlarge; and this time the enlargement will be nothing short of a whole army, which will have to go out and fight with the invaders for all that we have, as well as for the things and persons whom we were describing above.
Why?
he said; are they not capable of defending themselves?
No, I said; not if we were right in the principle which was acknowledged by all of us when we were framing the State: the principle, as you will remember, was that one man cannot practise many arts with success.
Very true, he said.
But is not war an art?
Certainly.
And an art requiring as much attention as shoemaking?
Quite true.
And the shoemaker was not allowed by us to be a husbandman, or a weaver, or a builder--in order that we might have our shoes well made; but to him and to every other worker was assigned one work for which he was by nature fitted, and at that he was to continue working all his life long and at no other; he was not to let opportunities slip, and then he would become a good workman.
