When the judicial is united to the executive power, it is scarce possible that justice should not frequently be sacrificed to what is vulgarly called polities.The persons entrusted with the great interests of the state may, even without any corrupt views, sometimes imagine it necessary to sacrifice to those interests the rights of a private man.But upon the impartial administration of justice depends the liberty of every individual, the sense which he has of his own security.In order to make every individual feel himself perfectly secure in the possession of every right which belongs to him, it is not only necessary that the judicial should be separated from the executive power, but that it should be rendered as much as possible independent of that power.The judge should not be liable to be removed from his office according to the caprice of that power.The regular the good-will or even upon the good economy payment of his salary should not depend upon of that power.
PART 3
Of the Expense of Public Works and Public Institutions THE third and last duty of the sovereign or commonwealth is that of erecting and maintaining those public institutions and those public works, which, though they may be in the highest degree advantageous to a great society, are, however, of such a nature that the profit could never repay the expense to any individual or small number of individuals, and which it therefore cannot be expected that any individual or small number of individuals should erect or maintain.The performance of this duty requires, too, very different degrees of expense in the different periods of society.
After the public institutions and public works necessary for the defence of the society, and for the administration of justice, both of which have already been mentioned, the other works and institutions of this kind are chiefly those for facilitating the commerce of the society, and those for promoting the instruction of the people.The institutions for instruction are of two kinds: those for the education of youth, and those for the instruction of people of all ages.The consideration of the manner in which the expense of those different sorts of public, works and institutions may be most properly defrayed will divide this third part of the present chapter into three different articles.
ARTICLE 1
Of the Public Works and Institutions for facilitating the Commerce of the Society And, first, of those which are necessary for facilitating Commerce in general.
That the erection and maintenance of the public works which facilitate the commerce of any country, such as good roads, bridges, navigable canals, harbours, etc., must require very different degrees of expense in the different periods of society is evident without any proof.The expense of ****** and maintaining the public roads of any country must evidently increase with the annual produce of the land and labour of that country, or with the quantity and weight of the goods which it becomes necessary to fetch and carry upon those roads.The strength of a bridge must be suited to the number and weight of the carriages which are likely to pass over it.The depth and the supply of water for a navigable canal must be proportioned to the number and tonnage of the lighters which are likely to carry goods upon it; the extent of a harbour to the number of the shipping which are likely to take shelter in it.
It does not seem necessary that the expense of those public works should be defrayed from that public revenue, as it is commonly called, of which the collection and application is in most countries assigned to the executive power.The greater part of such public works may easily be so managed as to afford a particular revenue sufficient for defraying their own expense, without bringing any burden upon the general revenue of the society.
A highway, a bridge, a navigable canal, for example, may in most cases be both made and maintained by a small toll upon the carriages which make use of them: a harbour, by a moderate port-duty upon the tonnage of the shipping which load or unload in it.The coinage, another institution for facilitating commerce, in many countries, not only defrays its own expense, but affords a small revenue or seignorage to the sovereign.The post-office, another institution for the same purpose, over and above defraying its own expense, affords in almost all countries a very considerable revenue to the sovereign.
When the carriages which pass over a highway or a bridge, and the lighters which sail upon a navigable canal, pay toll in proportion to their weight or their tonnage, they pay for the maintenance of those public works exactly in proportion to the wear and tear which they occasion of them.It seems scarce possible to invent a more equitable way of maintaining such works.This tax or toll too, though it is advanced by the carrier, is finally paid by the consumer, to whom it must always be charged in the price of the goods.As the expense of carriage, however, is very much reduced by means of such public works, the goods, notwithstanding the toll come cheaper to the consumer than the; could otherwise have done; their price not being so much raised by the toll as it is lowered by the cheapness of the carriage.The person who finally pays this tax, therefore, gains by the application more than he loses by the payment of it.His payment is exactly in proportion to his gain.It is in reality no more than a part of that gain which he is obliged to give up in order to get the rest.It seems impossible to imagine a more equitable method of raising a tax.
When the toll upon carriages of luxury upon coaches, post-chaises, etc., is made somewhat higher in proportion to their weight than upon carriages of necessary use, such as carts, waggons, etc., the indolence and vanity of the rich is made to contribute in a very easy manner to the relief of the poor, by rendering cheaper the transportation of heavy goods to all the different parts of the country.
