Now as a community of wives is attended with many other difficulties, so neither does the cause for which he would frame his government in this manner seem agreeable to reason, nor is it capable of producing that end which he has proposed, and for which he says it ought to take place; nor has he given any particular directions for putting it in practice. Now I also am willing to agree with Socrates in the principle which he proceeds upon, and admit that the city ought to be one as much as possible; and yet it is evident that if it is contracted too much, it will be no longer a city, for that necessarily supposes a multitude; so that if we proceed in this manner, we shall reduce a city to a family, and a family to a single person: for we admit that a family is one in a greater degree than a city, and a single person than a family; so that if this end could be obtained, it should never be put in practice, as it would annihilate the city; for a city does not only consist of a large number of inhabitants, but there must also be different sorts; for were they all alike, there could be no city; for a confederacy and a city are two different things; for a confederacy is valuable from its numbers, although all those who compose it are men of the same calling; for this is entered into for the sake of mutual defence, as we add an additional weight to make the scale go down. The same distinction prevails between a city and a nation when the people are not collected into separate villages, but live as the Arcadians. Now those things in which a city should be one are of different sorts, and in preserving an alternate reciprocation of power between these, the safety thereof consists (as I have already mentioned in my treatise on Morals), for amongst freemen and equals this is absolutely necessary; for all cannot govern at the same time, but either by the year, or according to some other regulation or time, by which means every one in his turn will be in office; as if the shoemakers and carpenters should exchange occupations, and not always be employed in the same calling. But as it is evidently better, that these should continue to exercise their respective trades; so also in civil society, where it is possible, it would be better that the government should continue in the same hands; but where it [1261b] is not (as nature has made all men equal, and therefore it is just, be the administration good or bad, that all should partake of it), there it is best to observe a rotation, and let those who are their equals by turns submit to those who are at that time magistrates, as they will, in their turns, alternately be governors and governed, as if they were different men: by the same method different persons will execute different offices. From hence it is evident, that a city cannot be one in the manner that some persons propose; and that what has been said to be the greatest good which it could enjoy, is absolutely its destruction, which cannot be: for the good of anything is that which preserves it. For another reason also it is clear, that it is not for the best to endeavour to make a city too much one, because a family is more sufficient in itself than a single person, a city than a family; and indeed Plato supposes that a city owes its existence to that sufficiency in themselves which the members of it enjoy. If then this sufficiency is so desirable, the less the city is one the better.
