THE PEOPLE (continued)  
A body politic may be measured in two ways—either by the extent of its territory, or by the number of its people; and there is, between these two measurements, a right relation which makes the State really great. The men make the State, and the territory sustains the men; the right relation therefore is that the land should suffice for the maintenance of the inhabitants, and that there should be as many inhabitants as the land can maintain. In this proportion lies the maximum strength of a given number of people; for if there is too much land, it is troublesome to guard and inadequately cultivated, produces more than is needed, and soon gives rise to wars of defence; if there is not enough, the State depends on its neighbours for what it needs over and above, and this soon gives rise to wars of offence. Every people, to which its situation gives no choice save that between commerce and war, is weak in itself: it depends on its neighbours, and on circumstances; its existence can never be more than short and uncertain. It either conquers others, and changes its situation, or it is conquered and becomes nothing. Only insignificance or greatness can keep it free.
No fixed relation can be stated between the extent of the territory and the population that are adequate one to the other, both because of the differences in the quality of land, in its fertility, in the nature of its products, and in the influence of climate, and because of the different tempers of those who inhabit it; for some in a fertile country consume little, and others on an ungrateful soil much. The greater or less fecundity of women, the conditions that are more or less favourable in each country to the growth of population, and the influence the legislator can hope to exercise by his institutions, must also be taken into account. The legislator therefore should not go by what he sees, but by what he foresees; he should stop not so much at the state in which he actually finds the population, as at that to which it ought naturally to attain. Lastly, there are countless cases in which the particular local circumstances demand or allow the acquisition of a greater territory than seems necessary. Thus, expansion will be great in a mountainous country, where the natural products, i.e. woods and pastures, need less labour, where we know from experience that women are more fertile than in the plains, and where a great expanse of slope affords only a small level tract that can be counted on for vegetation. On the other hand, contraction is possible on the coast, even in lands of rocks and nearly barren sands, because there fishing makes up to a great extent for the lack of land-produce, because the inhabitants have to congregate together more in order to repel pirates, and further because it is easier to unburden the country of its superfluous inhabitants by means of colonies.
To these conditions of law-giving must be added one other which, though it cannot take the place of the rest, renders them a............
