"In my opinion the true and healthy constitution of the State is the one which I have described. But if you wish also to see a State at fever heat, I have no objection. For I suspect that many will not be satisfied with the simpler way of life. They will be for adding ... dainties, and perfumes, and incense, and courtesans, and cakes, all these not of one sort only, but in every variety ... 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."
