ON THE INFLUENCE OF GOVERNMENT.
CHAPTER I.
OF THE FUNCTIONS OF GOVERNMENT IN GENERAL.
§ 1.One of the most disputed questions both in political science and in practical statesmanship at this particular period, relates to the proper limits of the functions and agency of governments. At other times it has been a subject of controversy how governments should be constituted, and according to what principles and rules they should exercise their authority; but it is now almost equally a question, to what departments of human affairs that authority should extend. And when the tide sets so strongly towards changes in government and legislation, as a means of improving the condition of mankind, this discussion is more likely to increase than to diminish in interest. On the one hand, impatient reformers, thinking it easier and shorter to get possession of the government than of the intellects and dispositions of the public, are under a constant temptation to stretch the province of government beyond due bounds: while, on the other, mankind have been so much accustomed by their rulers to interference for purposes other than the public good, or under ​an erroneous conception of what that good requires, and so many rash proposals are made by sincere lovers of improvement, for attempting, by compulsory regulation, the attainment of objects which can only be effectually or only usefully compassed by opinion and discussion, that there has grown up a spirit of resistance in limine to the interference of government, merely as such, and a disposition to restrict its sphere of action within the narrowest bounds. From differences in the historical development of different nations, not necessary to be here dwelt upon, the former excess, that of exaggerating the province of government, prevails most, both in theory and in practice, among the Continental nations, while in England the contrary spirit has hitherto been predominant.
The general principles of the question, in so far as it is a question of principle, I shall make an attempt to determine in a later chapter of this Book: after first considering the effects produced by the conduct of government in the exercise of the functions universally acknowledged to belong to it. For this purpose, there must be a specification of the functions which are either inseparable from the idea of a government, or are exercised habitually and without objection by all governments; as distinguished from those respecting which it has been considered questionable whether governments should exercise them or not. The former may be termed the necessary, the latter the optional, functions of government. By the term optional it is not meant to imply, that it can ever be a matter of indifference, or of arbitrary choice, whether the government should or should not take upon itself the functions in question; but only that the expediency of its exercising them does not amount to necessity, and is a subject on which diversity of opinion does or may exist.
§ 2.In attempting to enumerate the necessary functions of government, we find them to be considerably more multifarious than most people are at first aware of, and not capable ​of being circumscribed by those very definite lines of demarcation, which, in the inconsiderateness of popular discussion, it is often attempted to draw round them. We sometimes, for example, hear it said that governments ought to confine themselves to affording protection against force and fraud: that, these two things apart, people should be free agents, able to take care of themselves, and that so long as a person practises no violence or deception, to the injury of others in person or property, legislatures and governments are in no way called on to concern themselves about him. But why should people be protected by their government, that is, by their own collective strength, against violence and fraud, and not against other evils, except that the expediency is more obvious? If nothing, but what people cannot possibly do for themselves, can be tit to be done for them by government, people might be required to protect themselves by their skill and courage even against force, or to beg or buy protection against it, as they actually do where the government is not capable of protecting them: and against fraud every one has the protection of his own wits. But without further anticipating the discussion of principles, it is sufficient on the present occasion to consider facts.
Under which of these heads, the repression of force or of fraud, are we to place the operation, for example, of the laws of inheritance? Some such laws must exist in all societies. It may be said, perhaps, that in this matter government has merely to give effect to the disposition which an individual makes of his own property by will. This, however, is at least extremely disputable; there is probably no country by whose laws the power of testamentary disposition is perfectly absolute. And suppose the very common case of there being no will: does not the law, that is, the government, decide on principles of general expediency, who shall take the succession? and in case the successor is in any manner incompetent, does it not appoint persons, frequently officers of its own, to collect the property and apply it to his benefit? There are ​many other cases in which the government undertakes the administration of property, because the public interest, or perhaps only that of the particular persons concerned, is thought to require it. This is often done in case of litigated property; and in cases of judicially declared insolvency. It has never been contended that in doing these things, a government exceeds its province.
Nor is the function of the law in denning property itself, so simple a thing as may be supposed. It may be imagined, perhaps, that the law has only to declare and protect the right of every one to what he has himself produced, or acquired by the voluntary consent, fairly obtained, of those who produced it. But is there nothing recognised as property except what has been produced? Is there not the earth itself, its forests and waters, and all other natural riches, above and below the surface? These are the inheritance of the human race, and there must be regulations for the common enjoyment of it. What rights, and under what conditions, a person shall be allowed to exercise over any portion of this common inheritance, cannot be left undecided. No function of government is less optional than the regulation of these things, or more completely involved in the idea of civilized society.
Again, the legitimacy is conceded of repressing violence or treachery; but under which of these heads are we to place the obligation imposed on people to perform their contracts? Non-performance does not necessarily imply fraud; the person who entered into the contract may have sincerely intended to fulfil it: and the term fraud, which can scarcely admit of being extended even to the case of voluntary breach of contract when no deception was practised, is certainly not applicable when the omission to perform is a case of negligence. Is it no part of the duty of governments to enforce contracts? Here the doctrine of non-interference would no doubt be stretched a little, and it would be said, that enforcing contracts is not regulating the ​affairs of individuals at the pleasure of government, but giving effect to their own expressed desire. Let us acquiesce in this enlargement of the restrictive theory, and take it for what it is worth. But governments do not limit their concern with contracts to a simple enforcement. They take upon themselves to determine what contracts are fit to be enforced. It is not enough that one person, not being either cheated or compelled, makes a promise to another. There are promises by which it is not for the public good that persons should have the power of binding themselves. To say nothing of engagements to do something contrary to law, there are engagements which the law refuses to enforce, for reasons connected with the interest of the promiser, or with the general policy of the state. A contract by which a person sells himself to another as a slave, would be declared void by the tribunals of this and of most other European countries. There are few nations whose laws enforce a contract for what is looked upon as prostitution, or any matrimonial engagement of which the conditions vary in any respect from those which the law has thought fit to prescribe. But when once it is admitted that there are any engagements which for reasons of expediency the law ought not to enforce, the same question is necessarily opened with respect to all engagements. Whether, for example, the law should enforce a contract to labour, when the wages are too low or the hours of work too severe: whether it should enforce a contract by which a person binds himself to remain, for more than a very limited period, in the service of a given individual: whether a contract of marriage, entered into for life, should continue to be enforced against the deliberate will of the persons, or of either of the persons, who entered into it. Every question which can possibly arise as to the policy of contracts, and of the relations which they establish among human beings, is a question for the legislator; and one which he cannot escape from considering, and in some way or other deciding.
​Again, the prevention and suppression of force and fraud afford appropriate employment for soldiers, policemen, and criminal judges; but there are also civil tribunals. The punishment of wrong is one business of an administration of justice, but the decision of disputes is another. Innumerable disputes arise between persons, without mala fides on either side, through misconception of their legal rights, or from not being agreed about the facts, on the proof of which those rights are legally dependent. Is it not for the general interest that the State should appoint persons to clear up these uncertainties and terminate these disputes? It cannot be said to be a case of absolute necessity. People might appoint an arbitrator, and engage to submit to his decision; and they do so where there are no courts of justice, or where the courts are not trusted, or where their delays and expenses, or the irrationality of their rules of evidence, deter people from resorting to them. Still, it is universally thought right that the State should establish civil tribunals; and if their defects often drive people to have recourse to substitutes, even then the power held in reserve of carrying the case before a legally constituted court, gives to the substitutes their principal efficacy.
Not only does the State undertake to decide disputes, it takes precautions beforehand that disputes may not arise. The laws of most countries lay down rules for determining many things, not because it is of much consequence in what way they are determined, but in order that they may be determined somehow, and there may be no question on the subject. The law prescribes forms of words for many kinds of contract, in order that no dispute or misunderstanding may arise about their meaning: it makes provision that if a dispute does arise, evidence shall be procurable for deciding it, by requiring that the document be attested by witnesses and executed with certain formalities. The law preserves authentic evidence of facts to which legal consequences are attached, by keeping a registry of such facts; as of births, ​deaths, and marriages, of wills and contracts, and of judicial proceedings. In doing these things, it has never been alleged that government oversteps the proper limits of its functions.
Again, however wide a scope we may allow to the doctrine that individuals are the proper guardians of their own interests, and that government owes nothing to them but to save them from being interfered with by other people, the doctrine can never be applicable to any persons but those who are capable of acting in their own behalf. The individual may be an infant, or a lunatic, or fallen into imbecility. The law surely must look after the interests of such persons. It does not necessarily do this through officers of its own. It often devolves the trust upon some relative or connexion. But in doing so is its duty ended? Can it make over the interests of one person to the control of another, and be excused from supervision, or from holding the person thus trusted, responsible for the discharge of the trust?
There is a multitude of cases in which governments, with general approbation, assume powers and execute functions for which no reason can be assigned except the simple one, that they conduce to general convenience. Wo may take as an example, the function (which is a monopoly too) of coining money. This is assumed for no more recondite purpose than that of saving to individuals the trouble, delay, and expense of weighing and assaying. No one, however, even of those most jealous of state interference, has objected to this as an improper exercise of the powers of government. Prescribing a set of standard weights and measures is another instance. Paving, lighting, and cleansing the streets and thoroughfares, is another; whether done by the general government, or as is more usual, and generally more advisable, by a municipal authority. Making or improving harbours, building lighthouses, making surveys in order to have accurate maps and charts, raising dykes to keep the sea out, and embankments to keep rivers in, are cases in point.
​Examples might be indefinitely multiplied without intruding on any disputed ground. But enough has been said to show that the admitted functions of government embrace a much wider field than can easily be included within the ring-fence of any restrictive definition, and that it is hardly possible to find any ground of justification common to them all, except the comprehensive one of general expediency; nor to limit the interference of government by any universal rule, save the simple and vague one, that it should never be admitted but when the case of expediency is strong.
§ 3.Some observations, however, may be usefully bestowed on the nature of the considerations on which the question of government interference is most likely to turn, and on the mode of estimating the comparative magnitude of the expediencies involved. This will form the last of the three parts, into which our discussion of the principles and effects of government interference may conveniently be divided. The following will be our division of the subject. We shall first consider the economical effects arising from the manner in which governments perform their necessary and acknowledged functions.
We shall then pass to certain governmental interferences of what I have termed the optional kind (i.e. overstepping the boundaries of the universally acknowledged functions) which have heretofore taken place, and in some cases still take place, under the influence of false general theories. It will lastly remain to inquire whether, independently of any false theory, and consistently with a correct view of the laws which regulate human affairs, there be any cases of the optional class in which governmental interference is really advisable, and what are those cases.
The first of these divisions is of an extremely miscellaneous character: since the necessary functions of government, aud those which are so manifestly expedient that they have never or very rarely been objected to, are, as already ​pointed out, too various to be brought under any very simple classification. Those, however, which are of principal importance, which alone it is necessary here to consider, may be reduced to the following general heads.
First, the means adopted by governments to raise the revenue which is the condition of their existence.
Secondly, the nature of the laws which they prescribe on the two great subjects of Property and Contracts.
Thirdly, the excellences or defects of the system of means by which they enforce generally the execution of their laws, namely, their judicature and police.
We commence with the first head, that is, with the theory of Taxation.
