A city composed of such men must therefore consist of slaves and masters, not freemen; where one party must hate, and the other despise, where there could be no possibility of friendship or political community: for community supposes affection; for we do not even on the road associate with our enemies. It is also the genius of a city to be composed as much as possible of equals; which will be most so when the inhabitants are in the middle state: from whence it follows, that that city must be best framed which is composed of those whom we say are naturally its proper members. It is men of this station also who will be best assured of safety and protection; for they will neither covet what belongs to others, as the poor do; nor will others covet what is theirs, as the poor do what belongs to the rich; and thus, without plotting against any one, or having any one plot against them, they will live free from danger: for which reason Phocylides wisely wishes for the middle state, as being most productive of happiness. It is plain, then, that the most perfect political community must be amongst those who are in the middle rank, and those states are best instituted wherein these are a larger and more respectable part, if possible, than both the other; or, if that cannot be, at least than either of them separate; so that being thrown into the balance it may prevent either scale from preponderating. It is therefore the greatest happiness which the citizens can enjoy to possess a moderate and convenient fortune; for when some possess too much, and others nothing at [1296a] all, the government must either be in the hands of the meanest rabble or else a pure oligarchy; or, from the excesses of both, a tyranny; for this arises from a headstrong democracy or an oligarchy, but very seldom when the members of the community are nearly on an equality with each other. We will assign a reason for this when we come to treat of the alterations which different states are likely to undergo. The middle state is therefore best, as being least liable to those seditions and insurrections which disturb the community; and for the same reason extensive governments are least liable to these inconveniences; for there those in a middle state are very numerous, whereas in small ones it is easy to pass to the two extremes, so as hardly to have any in a medium remaining, but the one half rich, the other poor: and from the same principle it is that democracies are more firmly established and of longer continuance than oligarchies; but even in those when there is a want of a proper number of men of middling fortune, the poor extend their power too far, abuses arise, and the government is soon at an end.
