And suppose that, before engaging, our citizens send an embassy to one of the two cities, telling them what is the truth: Silver and gold we neither have nor are permitted to have, but you may; do you therefore come and help us in war, and take the spoils of the other city: Who, on hearing these words, would choose to fight against lean wiry dogs, rather than, with the dogs on their side, against fat and tender sheep? That is not likely; and yet there might be a danger to the poor State if the wealth of many States were to be gathered into one. But how simple of you to use the term State at all of any but our own! Why so? You ought to speak of other States in the plural number; not one of them is a city, but many cities, as they say in the game. For indeed any city, however small, is in fact divided into two, one the city of the poor, the other of the rich; these are at war with one another; and in either there are many smaller divisions, and you would be altogether beside the mark if you treated them all as a single State. But if you deal with them as many, and give the wealth or power or persons of the one to the others, you will always have a great many friends and not many enemies. And your State, while the wise order which has now been prescribed continues to prevail in her, will be the greatest of States, I do not mean to say in reputation or appearance, but in deed and truth, though she number not more than a thousand defenders. A single State which is her equal you will hardly find, either among Hellenes or barbarians, though many that appear to be as great and many times greater. That is most true, he said. And what, I said, will be the best limit for our rulers to fix when they are considering the size of the State and the amount of territory which they are to include, and beyond which they will not go? What limit would you propose? I would allow the State to increase so far as is consistent with unity; that, I think, is the proper limit. Very good, he said. Here then, I said, is another order which will have to be conveyed to our guardians: Let our city be accounted neither large nor small, but one and self-sufficing. And surely, said he, this is not a very severe order which we impose upon them. And the other, said I, of which we were speaking before is lighter still,—I mean the duty of degrading the offspring of the guardians when inferior, and of elevating into the rank of guardians the offspring of the lower classes, when naturally superior. The intention was, that, in the case of the citizens generally, each individual should be put to the use for which nature intended him, one to one work, and then every man would do his own business, and be one and not many; and so the whole city would be one and not many. Yes, he said; that is not so difficult.
