The State, in this conception has but three functions—defence, justice and "the duty of erecting and maintaining certain public works and certain public institutions which it can never be for the interest of any individual, or small number of individuals, to erect and maintain." The State, in fact, is simply to provide the atmosphere in which production is possible. Nor does Smith conceal his thought that the main function of justice is the protection of property. "The affluence of the rich," he wrote, "excites the indignation of the poor, who are often both driven by want and prompted by envy to invade their possessions. It is only under the shelter of the civil magistrate that the owner of that valuable property, acquired by the labor of many years, or perhaps many successive generations, can sleep a single night in security." The attitude, indeed, is intensified by his constant sense that the capital which makes possible new productivity is the outcome of men's sacrifice; to protect it is thus to safeguard the sources of wealth itself. And even if the State is entrusted with education and the prevention of disease, this is rather for the general benefit they confer and the doubt that private enterprise would find them profitable than as the expression of a general rule. Collective effort of every kind awakened in him a deep distrust. Trade regulations such as the limitation of apprenticeship he condemned as "manifest encroachment upon the just liberty of the workman and of those who may be disposed to employ him." Even educational establishments are suspect on the ground—not unnatural after his own experience of Oxford—that their possibilities of comfort may enervate the natural energies of men.

The key to this attitude is clear enough. The improvement of society is due, he thinks not to the calculations of government but to the natural instincts of economic man. We cannot avoid the impulse to better our condition; and the less its effort is restrained the more certain it is that happiness will result. We gain, in fact, some sense of its inherent power when we bear in mind the magnitude of its accomplishment despite the folly and extravagance of princes. Therein we have some index of what it would achieve if left unhindered to work out its own destinies. Human institutions continually thwart its power; for those who build those institutions are moved rather "by the momentary fluctuations of affairs" than their true nature. "That insidious and crafty animal, vulgarly called a politician or statesman" meets little mercy for his effort compared to the magic power of the natural order. "In all countries where there is a tolerable security," he writes, "every man of common understanding will endeavor to employ whatever stock he can command in procuring either present enjoyment or future profit." Individual spontaneity is thus the root of economic good; and the real justification of the state is the protection it affords to this impulse. Man, in fact, is by nature a trader and he is bound by nature to discover the means most apt to progress.

Nor was he greatly troubled by differences of fortune. Like most of the Scottish school, especially Hutcheson and Hume, he thought that men are much alike in happiness, whatever their station or endowments. For there is a "never-failing certainty" that "all men sooner or later accommodate themselves to whatever becomes their permanent situation"; though he admits that there is a certain level below which poverty and misery go hand in hand. But, for the most part, happiness is simply a state of mind; and he seems to have had but little suspicion that differences of wealth might issue in dangerous social consequence. Men, moreover, he regarded as largely equal in their original powers; and differences of character he ascribes to the various occupations implied in the division of labor. Each man, therefore, as he follows his self-interest promotes the general happiness of society. That principle is inherent in the social order. "Every man," he wrote in the Moral Sentiments, "is by nature first and principally recommended to his own care" and therein he is "led by an invisible hand to promote an end which was no part of his intention." The State, that is to say, is the sum of individual goods; whereby to better ourselves is clearly to its benefit. And that desire "which comes with us from the womb and never leaves us till we go to the grave" is the more efficacious the less it is restrained by governmental artifice. For we know so well what makes us happy that none can hope to help us so much as we help ourselves.

Enlightened selfishness is thus the root of prosperity; but we must not fall into the easy fallacy which makes Smith deaf to the plaint of the poor. He urged the employer to have regard to the health and welfare of the worker, a regard which was the voice of reason and humanity. Where there was conflict between love of the status quo and a social good which Revolution alone could achieve, he did not, at least in the Moral Sentiments, hesitate to choose the latter. Order was, for the most part, indispensable; but "the greatest and noblest of all characters" he made the reformer of the State. Yet he is too impressed by the working of natural economic laws to belittle their influence. Employers, in his picture, are little capable of benevolence or charity. Their rule is the law of supply and demand and not the Sermon on the Mount. They combine without hesitation to depress wages to the lowest point of subsistence. They seize every occasion of commercial misfortune to make better terms for themselves; and the greater the poverty the more submissive do servants become so that scarcity is naturally regarded as more favorable to industry.

Obviously enough, the inner hinge of all this argument is Smith's conception of nature. Nor can there be much doubt of what he thought its inner substance. Facile distinctions such as the effort of Buckle to show that while in the Moral Sentiments Adam Smith was dealing with the unselfish side of man's nature, in the Wealth of Nations he was dealing with a group of facts which required the abstraction of such altruistic elements, are really beside the point. Nature for Smith is simply the spontaneous action of human character unchecked by hindrances of State. It is, as Bonar has aptly said, "a vindication of the unconscious law present in the separate actions of men when these actions are directed by a certain strong personal motive." Adam Smith's argument is an assumption that the facts can be made to show the relative powerlessness of institutions in the face of economic laws grounded in human psychology. The psychology itself is relatively simple, and, at least in the Wealth of Nations not greatly different from the avowed assumptions of utilitarianism. He emphasizes the strength of reason in the economic field, and his sense that it enables men to judge much better of their best interests than an external authority can hope to do. And therefore the practices accomplished by this reason are those in which the impulses of men are to be found. The order they represent is the natural order; and whatever hinders its full operation is an unwise check upon the things for which men strive.

Obviously enough, this attitude runs the grave risk of seeming to abstract a single motive—the desire for wealth—from the confused welter of human impulses and to make it dominant at the expense of human nature itself. A hasty reading of Adam Smith would, indeed, confirm that impression; and that is perhaps why he seemed to Ruskin to blaspheme human nature. But a more careful survey, particularly when the Moral Sentiments is borne in mind suggests a different conclusion. His attitude is implicit in the general medium in which he worked. What he was trying to do was less to emphasize that men care above all things for the pursuit of wealth than that no institutional modifications are able to destroy the power of that motive to labor. There is too much history in the Wealth of Nations to make tenable the hypothesis of complete abstraction. And there is even clear a sense of a nature behind his custom when he speaks of a "sacred regard" for life, and urges that every man has property in his own labor. The truth here surely is that Smith was living in a time of commercial expansion. What was evident to him was the potential wealth to be made available if the obsolete system of restraint could be destroyed. Liberty to him meant absence of restraint not because its more positive aspect was concealed from him but rather because the kind of freedom wanted in the environment in which he moved was exactly that for which he made his plea. There is a hint that freedom as a positive thing was known to him from the fact that he relied upon education to relieve the evils of the division of labor. But the general context of his book required less emphasis upon the virtues of state-interference than upon its defects. His cue was to show that all the benefits of regulation had been achieved despite its interference; from which, of course, it followed that restraint was a matter of supererogation.

III

It would be tedious to praise the Wealth of Nations. It may be doubtful whether Buckle's ecstatic judgment that it has had more influence than any other book in the world was justified even when he wrote; but certainly it is one of the seminal books of the modern time. What is more important is to note the perspective in which its main teaching was set. He wrote in the midst of the first significant beginnings of the Industrial Revolution; and his emphatic approval of Watt's experiments suggests that he was not unalive to its importance. Yet it cannot in any full sense be said that the Industrial Revolution has a large part in his book. The picture of industrial organization and its possibilities is too simple to suggest that he had caught any far reaching glimpse into the future. Industry, for him, is still in the last stage of handicraft; it is a matter of skillful workmanship and not of mechanical appliance. Capital is still the laborious result of parsimony. Credit is spoken of rather in the tones of one who sees it less as a new instrument of finance than a dangerous attempt by the aspiring needy to scale the heights of wealth. Profits are always a justified return for productive labor; interest the payment for the use of the owner's past parsimony. Business is still the middleman distributing to the consumer on a small scale. He did not, or could not, conceive of an industry either so vast or so depersonalized as at present. He was rather writing of a system which, like the politics of the eighteenth century, had reached an equilibrium of passable comfort. His natural order was, at bottom, the beatification of that to which this equilibrium tended. Its benefits might be improved by free trade and free workmanship; but, upon the whole, he saw no reason to call in question its fundamental dogmas.

Therein, of course, may be found the main secret of his omissions. The problem of labor finds no place in his book. The things that the poor have absent from their lives, that concept of a national minimum below which no State can hope to fulfil even the meanest of its aims, of these he has no conception. Rather the note of the book is a quiet optimism, impressed by the possibilities of constant improvement which lie imbedded in the human impulse to better itself. What he did not see is the way in which the logical outcome of the system he describes may well be the attainment of great wealth at a price in human cost that is beyond its worth. Therein, it is clear, all individualistic theories of the state miss the true essence of the social bond. Those who came after Adam Smith saw only half his problem. He wrote a consumer's theory of value. But whereas he had in mind a happy and contented people, the economics of Ricardo and Malthus seized upon a single element in human nature as that which alone the State must serve. Freedom from restraint came ultimately to mean a judgment upon national well-being in terms of the volume of trade. "It is not with happiness," said Nassau Senior, "but with wealth that I am concerned as a political economist; and I am not only justified in omitting, but am perhaps bound to omit, all considerations which have no influence upon wealth."

In such an aspect, it was natural for the balance of investigation to swing towards the study of the technique of production; and with the growing importance of capital, as machinery was introduced, the worker, without difficulty, became an adjunct, easily replaced, to the machine. What was remembered then was the side of Adam Smith which looked upon enlightened selfishness as the key to social good. Regulation became anathema even when the evils it attempted to restrain were those which made the mass of the people incapable of citizenship. Even national education was regarded as likely to destroy initiative; or, as a pauper's dole which men of self-respect would regard with due abhorrence. The State, in short, ceased to concern itself with justice save insofar as the administration of a judicial code spelled the protection of the new industrial system. Nothing is more striking in the half-century after Adam Smith than the optimism of the economist and the business man in contrast to the hopeless despair of labor. That men can organize to improve their lot was denied with emphasis, so that until Francis Place even the workers themselves were half-convinced. The manufacturers were the State; and the whole intellectual strength of economics was massed to prove the rightness of the equation. The literature of protest, men like Hall and Thompson, Hodgskin and Bray, exerted no influence upon the legislation of the time; and Robert Owen was deemed an amiable eccentric rather than the prophet of a new hope. The men who succeeded, as Wilberforce, carried out to the letter the unstated assumptions of Puritan economics. The poor were consigned to a God whose dictates were by definition beneficent; and if they failed to understand the curious incidence of his rewards that was because his ways were inscrutable. No one who reads the tracts of writers like Harriet Martineau can fail to see how pitiless was the operation of this attitude. Life is made a struggle beneficent, indeed, but deriving its ultimate meaning from the misery incident to it. The tragedy is excused because the export-trade increases in its volume. The iron law of wages, the assumed transition of every energetic worker to the ranks of wealth, the danger lest the natural ability of the worker to better his condition be sapped by giving to him that which his self-respect can better win—these became the unconscious assumptions of all economic discussion.
