Much the same principle will apply to the territory of the state: every one would agree in praising the territory which is most entirely self-sufficing; and that must be the territory which is all-producing, for to have all things and to want nothing is sufficiency. In size and extent it should be such as may enable the inhabitants to live at once temperately and liberally in the enjoyment of leisure. Whether we are right or wrong in laying down this limit we will inquire more precisely hereafter, when we have occasion to consider what is the right use of property and wealth: a matter which is much disputed, because men are inclined to rush into one of two extremes, some into meanness, others into luxury.
It is not difficult to determine the general character of the territory which is required (there are, however, some points on which military authorities should be heard); it should be difficult of access to the enemy, and easy of egress to the inhabitants. Further, we require that the land as well as the inhabitants of whom we were just now speaking should be taken in at a single view, for a country which is easily seen can be easily protected. As to the position of the city, if we could have what we wish, it should be well situated in regard both to sea and land. This then is one principle, that it should be a convenient center for the protection of the whole country: the other is, that it should be suitable for receiving the fruits of the soil, and also for the bringing in of timber and any other products that are easily transported.
