Having considered the domestic life and manners of the ancients compared to those of the moderns, where in the main we seem rather superior so far as the present question is concerned, we shall now examine the political customs and institutions of both ages, and weigh their influence in retarding or forwarding the propagation of mankind.
Before the increase of the Roman power, or rather till its full establishment, almost all the nations which are the scene of ancient history were divided into small territories or petty {p125} commonwealths, where of course a great equality of fortune prevailed, and the centre of the government was always very near its frontiers.
This was the situation of affairs not only in Greece and Italy, but also in Spain, Gaul, Germany, Africa, and a great part of the Lesser Asia. And it must be owned that no institution could be more favourable to the propagation of mankind; for though a man of an overgrown fortune, not being able to consume more than another, must share it with those who serve and attend him, yet their possession being precarious, they have not the same encouragement to marriage as if each had a small fortune secure and independent. Enormous cities are, besides, destructive to society, beget vice and disorder of all kinds, starve the remoter provinces, and even starve themselves by the prices to which they raise all provisions. Where each man had his little house and field to himself, and each county had its capital, free and independent, what a happy situation of mankind! How favourable to industry and agriculture, to marriage and propagation! The prolific virtue of men, were it to act in its full extent, without that restraint which poverty and necessity imposes on it, would double the number every generation; and nothing surely can give it more liberty than such small commonwealths, and such an equality of fortune among the citizens. All small states naturally produce equality of fortune because they afford no opportunities of great increase, but small commonwealths much more by that division of power and authority which is essential to them.
