CHAPTER IV

As I have now finished what was introductory to this subject, and considered at large the nature of other states, it now remains that I should first say what ought to be the establishment of a city which one should form according to one's wish; for no good state can exist without a moderate proportion of what is necessary. Many things therefore ought to be forethought of as desirable, but none of them such as are impossible: I mean relative to the number of citizens and the extent of the territory: for as other artificers, such as the weaver and the shipwright, ought to have such materials as are fit for their work, since so much the better they are, by so much [1326a] superior will the work itself necessarily be; so also ought the legislator and politician endeavour to procure proper materials for the business they have in hand.

Most persons think that it is necessary for a city to be large to be happy: but, should this be true, they cannot tell what is a large one and what a small one; for according to the multitude of the inhabitants they estimate the greatness of it; but they ought rather to consider its strength than its numbers; for a state has a certain object in view, and from the power which it has in itself of accomplishing it, its greatness ought to be estimated; as a person might say, that Hippocrates was a greater physician, though not a greater man, than one that exceeded him in the size of his body: but if it was proper to determine the strength of the city from the number of the inhabitants, it should never be collected from the multitude in general who may happen to be in it; for in a city there must necessarily be many slaves, sojourners, and foreigners; but from those who are really part of the city and properly constitute its members;
