injustice, be defrayed by the general contributions of the whole society. This expense, however, is most immediately and directly beneficial to those who travel or carry goods from one place to another, and to those who consume such goods. The turnpike tolls in England, and the duties called peages in other countries, lay it altogether upon those two different sets of people, and thereby discharge the general revenue of the society from a very considerable burden.
The expense of the institutions for education and religious instruction, is likewise, no doubt, beneficial to the whole society, and may, therefore, without injustice, be defrayed by the general contribution of the whole society. This expense, however, might, perhaps, with equal propriety, and even with some advantage, be defrayed altogether by those who receive the immediate benefit of such education and instruction, or by the voluntary contribution of those who think they have occasion for either the one or the other.
When the institutions, or public works, which are beneficial to the whole society, either cannot be maintained altogether, or are not maintained altogether, by the contribution of such particular members of the society as are most immediately benefited by them; the deficiency must, in most cases, be made up by the general contribution of the whole society. The general revenue of the society, over and above defraying the expense of defending the society, and of supporting the dignity of the chief magistrate, must make up for the deficiency of many particular branches of revenue. The sources of this general or public revenue, I shall endeavour to explain in the following chapter.
