For what is sometimes called "literary property" is not property in the strict sense of the word. A book is not like a plough or a house. Its contents even when most original have been but colored, as it were, and rearranged and reinforced by the author's individual mind. Its substance always comes out of the common stock. It cannot be the author's own, as the bushel of wheat is the farmer's, who sowed the seed on his own land and threshed it in his own barn and carried it to market in his own wagon. The rights of the individual and the rights of the Community commingle more or less in private property of every kind, at least to the extent that the latter may tax the property if needful for the common wellbeing, as it is bound also legally to secure it to the owner when threatened by others; it is no part of the purpose of the present book to draw the wavering line in general between the rights of individuals and the rights of their Government as towards them; but the distinction between common property and copyrighted property is plain enough to everybody, and the Law puts emphasis on the distinction by making the one quickly terminable and the other continual. So then, when the Government under which the author resides, has given him a limited copyright within its own jurisdiction, it would seem as if the individual right in the premises had been sufficiently recognized alongside of the undoubted right of the Whole to the ultimate use of the labors of their own citizen.

When, however, it comes to International Copyright, which is an attempt to secure to authors of one country artificial privileges under restriction in selling their wares in all other countries, the argument breaks down. Even for the one country, in which the author lives and is taxable, the argument is not very strong, and hardly binds advanced public opinion either as to the grounds of it or even the practical benefits of it on the whole. By the attempted extension of it to all countries, its reasonableness disappears. Taxation cannot extend beyond the jurisdiction of the country taxing; and it certainly seems as if a legal privilege, beyond common law privileges, ought not by extension through the formal action of other countries to exempt from taxation (in case it were needful) the results of the original privilege. The purpose of International Copyright is not the blessed one as announced to the world by James Smithson, "the increase and diffusion of knowledge among mankind," but directly and artificially by means of legal restrictions the "increase" of the prices of books and of other "knowledge" to the masses of "mankind," and the "diffusion" of these extra prices as between authors and publishers. Protectionism does not seem to be one whit more respectable in this form than in the form of tariff-taxes on foreign works of art.

2. We have already seen in our first chapter the proofs of the proposition, that the Value of anything whatsoever bought and sold is determined by the Demand for it and the Supply of it then and there present. Also we have now seen at considerable length the main phases and grounds of the Demand for each of the three classes of Personal services bought and sold among men. The next topic in order is the Supply of personal services in the various markets. Here it will not be necessary to distinguish particularly the three classes of Services, inasmuch as the circumstances governing the Supply in each are substantially similar.

In Economics generally we have to deal chiefly with Persons, and only subordinately with Things; when we come to the Supply of personal services, answering to the Demand for them on the part of other persons, this point becomes conspicuous; and it is here, if anywhere, within the realm of our science, that we need to devote a word to a singular doctrine, that has been famous for nearly a century under the term of Malthusianism. Thomas Robert Malthus, 1766-1836, was an English clergyman and teacher, a wide traveller and keen observer of men, one who divided his time during a long life between cure and chair and the libraries of the Universities, published in 1798 his "Essay on the Principles of Population as it affects the Future Improvement of Society"; in this and in subsequent editions enlarged and enriched, he brought out with its proofs the core of his startling pronouncement, that the human race is found to increase in numbers in something like geometrical progression, while the means of subsistence for them on any given area of agriculture can only increase in something like arithmetical proportion; the United States was then doubling its population in 25 years, and he calculated that, at this rate, the inhabitants of any country in five centuries would increase to above a million times their present number, which would give England in that time more than twenty million millions of people, or more than could even get standing-room there; for this natural tendency of the law of human fecundity to outstrip the results of the law of returns from land, he saw no remedy except in checks to population, which he divided into the positive and the preventive, the first of which, such as war and famine and disease, increase the annual number of deaths; and the second of which, such as prudence in contracting marriage and temperance after marriage, diminish the number of births; and Malthus and his followers, among whom the famous Thomas Chalmers was prominent, were at great pains to inculcate upon the laboring classes the duty of later marriages and fewer children, as an indispensable condition of their rise in comforts, and of "the future improvement of Society."

These discussions have attracted great attention almost to the present day, and have been supposed to be very pertinent to the subject of wages, and thus to be an important part of Political Economy; but when one looks more closely, the force of that spring of population which the Creator has coiled up in the nature of man, as contrasted with the weakness of that power by which the earth brings forth sustenance for man, is seen to be a topic in Physiology and not in Political Economy at all. Political Economy presupposes the existence of Persons able and willing to make exchanges with each other, before it even begins its inquiries and generalizations. How they come into existence, the rate of their natural increase, and the ratio of this increase to the increase of food, however interesting as physiological questions, have clearly nothing to do with our Science. Each adult human being is as much constituted by Nature to receive personal services as to render them, in Economics each without exception receives when and because he renders, and all alike are naturally able to become capitalists also; economical laws present no obstacles, that we can see, to all men becoming rich, as we use that term; the town or city in which many people are growing rich simultaneously, is the best place in the world for other people to go to get rich in, and not at all towns in which other people are getting poorer; most men are unwilling, some perhaps may be unable, to fulfil the moral conditions of growing rich; while, we may depend upon it, the famines of the world have been caused more by the indolence and want of foresight of individuals, and especially by the monstrous maladministrations of Governments, than by any law of the increase of population.

Experience too has shown, that the strong impulse in mankind towards procreation is not too strong for the purpose intended by the Creator; that He who is the author of the impulses is author also of natural counterworkings of them; that, as men under moral and religious training come more and more under the influence of reason and affection, the preventive checks to population come silently and effectually into operation; and that, taking the world at large, food and comforts have more than kept pace with the stride of population, since its inhabitants as a whole were plainly never so well fed and clothed and housed as now. The abstract antagonism of the law of the increase of population with the law of the increase of food, or what we prefer to call the law of diminishing returns from Land, may be admitted, if one chooses to insist on it; but any practical tendency of these to come into collision, as the world is and is to be, is confidently denied. When Malthus wrote, and long afterwards, England was under the dominance of Protectionism; the wretched Corn-laws forbidding the importations of foreign grain, in order that the domestic growers might sell to their countrymen at artificial prices, and thus grow the richer as bread became the dearer, were only repealed in 1846; and the demonstrated ability of Great Britain under free trade to draw on the fertility of the whole world for the steadily and increasingly cheap maintenance of her people, demonstrates the irrelevancy of Malthusianism to the Science of Economics.

The Supply of personal services at any time or place in answer to the Demand for them, is affected by several important circumstances, which we shall now proceed to consider in their order.

(a) The agreeableness or disagreeableness of rendering a given set of services will affect the Supply of laborers at that point, and help to determine the rate of Wages paid to them; because the more agreeable employment will attract the larger number of laborers, will experience in consequence the press of competition, and the rate of wages then and there will be lessened thereby. The more disagreeable employment will feel less the pressure of numbers, and will secure, other things being equal, a higher rate of remuneration in consequence. Among the elements which, in spite of diversity of tastes, make any employment agreeable or disagreeable to the laborers, are (1) the less or greater exertion of physical strength required, (2) the healthfulness or unhealthfulness of the service, (3) its cleanliness or dirtiness, (4) the degree of liberty or confinement in it, (5) the safety or hazard of the employment, (6) the esteem or disrepute of it in public opinion. To illustrate each of these in order, the stone-mason, the glass-blower, the scavenger, the factory operative, the worker in a powder-mill, the smuggler, will each receive a larger compensation owing to the peculiar element of disagreeableness involved in his own personal service; and he will be able to demand and secure the higher rate through the action of this disagreeableness upon the Supply of such laborers. Of all these elements, public opinion is perhaps the most operative; and if this be favorable to an employment, and some social consideration be attached to it, and only common qualifications be required for it, the wages in it will infallibly be low. This is doubtless the main reason why so many young women prefer to teach, rather than be employed in mills or shops or offices, and why the wages of female teachers have been so remarkably low; although each of the elements of agreeableness specified above may also contribute something towards the same result. If a business be decidedly opposed to public opinion, it must hold out the inducement of a large reward, or nobody will engage in it. This explains the abnormal gains of the slave-trade, the liquor-business, of gambling-houses, and of lotteries.

(b) The easiness or difficulty of learning to render acceptably a given set of personal services, will have a quick and constant influence on the Supply of these services, and of course also on the rate of the return paid for them. The elements of this Difficulty in general are time, expense, lack of natural gifts, want of foresight on the part of those concerned, and lack of push and persistency on the part of the learner himself. To put a boy apprentice to a trade, for example, requires on the part of the parents a foresight, an ability to get on without his immediate help, and sometimes also an amount of money for his board and clothes which all parents do not possess; many boys too, who must acquire their skill to sell personal services when they are young, if at all, find on trial that they do not like the trade, or have not the requisite gifts, or fail in the appropriate patience and propulsion; and the consequence is, that the Supply of laborers along that particular line is lessened, and the right to demand and the ability to secure a higher rate of wages than is accorded to common laborers accompany the small supply, through the reduction of numbers which these obstacles at the entrance occasion and the consequent weakness of competition. This is one principal ground of the difference in the wages of skilled and unskilled laborers; the other being, as we have seen, the stronger and more constant Demand for the former, owing to the impulse imparted by Capital. All these points of difficulty at the outset apply still more strongly in the case of professional laborers, serving more effectually to thin out the ranks of these, and pushing upward still higher the gauge of compensation for the successful competitors.

(c) The constancy or inconstancy of prospective employment in a given business, is a consideration that affects the Supply within it, and then the wages. If the services be of such a character, that they can only be carried on during nine months of the year, the wages of the renderers will be greater by the day or the month than they would be, provided the services were in order during all the twelve months. The laborer is apt to look at the aggregate earnings of the year, and will hardly take up a trade which affords employment but a part of the time, unless some compensation can be found in the higher wages for that time. This is the chief reason why the wages of the mason and house-painter, in this climate at least, are higher than those of the blacksmith and carpenter. The coachman, also, may stand by his horses half the day or night with no call for his services, and must have, therefore, a proportionably higher fare from those whom he does transport. In general, it is found that men prefer a constant rendering with a lower rate of pay, than an inconstant one with a prospect of larger wages for the particular jobs actually done; and because the many prefer that, those who take up with the other are able to secure a higher relative rate of pay in their less eligible vocation. It must be noticed, however, as counterworking this, that some men have desire for intervals of leisure in their business, and for opportunity to make these intervals subservient to some avocation or other means of livelihood.
