The expence of defending the society, and that of supporting the dignity of the chief magistrate, are both laid out for the general benefit of the whole society. It is reasonable, therefore, that they should be defrayed by the general contribution of the whole society, all the different members contributing, as nearly as possible, in proportion to their respective abilities.

The expence of the administration of justice too, may, no doubt, be considered as laid out for the benefit of the whole society. There is no impropriety, therefore, in its being defrayed by the general contribution of the whole society. The persons, however, who give occasion to this expence are those who, by their injustice in one way or another, make it necessary to seek redress or protection from the courts of justice. The persons again most immediately benefited by this expence, are those whom the courts of justice either restore to their rights, or maintain in their rights. The expence of the administration of justice, therefore, may very properly be defrayed by the particular contribution of one or other, or both of those two different sets of persons, according as different occasions may require, that is, by the fees of court. It cannot be necessary to have recourse to the general contribution of the whole society, except for the conviction of those criminals who have not themselves any estate or fund sufficient for paying those fees.

Those local or provincial expences of which the benefit is local or provincial (what is laid out, for example, upon the police of a particular town or district) ought to be defrayed by a local or provincial revenue, and ought to be no burden upon the general revenue of the society. It is unjust that the whole society should contribute towards an expence of which the benefit is confined to a part of the society.

The expence of maintaining good roads and communications is, no doubt, beneficial to the whole society, and may, therefore, without any injustice, be defrayed by the general contribution of the whole society. This expence, 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 expence 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 expence, 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 expence 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.
