PREFACE.
The produce of the earth—all that is derived from its surface by the united application of labour, machinery, and capital, is divided among three classes of the community; namely, the proprietor of the land, the owner of the stock or capital necessary for its cultivation, and the labourers by whose industry it is cultivated.
But in different stages of society, the proportions of the whole produce of the earth which will be allotted to each of these classes, under the names of rent, profit, and wages, will be essentially different; depending mainly on the actual fertility of the soil, on the accumulation of capital and population, and on the skill, ingenuity, and instruments employed in agriculture.
To determine the laws which regulate this distribution, is the principal problem in Political Economy: much as the science has been improved by the writings of Turgot, Stuart, Smith, Say, Sismondi, and others, they afford very little satisfactory information respecting the natural course of rent, profit, and wages.
In 1815, Mr. Malthus in his "Inquiry into the Nature and Progress of Rent," and a Fellow of University College, Oxford, in his "Essay on the Application of Capital to Land," presented to the world, nearly at the same moment, the true doctrine of rent; without a knowledge of which it is impossible to understand the effect of the progress of wealth on profits and wages, or to trace satisfactorily the influence of taxation on different classes of the community, particularly when the commodities taxed are the productions immediately derived from the surface of the earth. Adam Smith, and the other able writers to whom I have alluded, not having viewed correctly the principles of rent, have, it appears to me, overlooked many important truths, which can only be discovered after the subject of rent is thoroughly understood.
To supply this deficiency, abilities are required of a far superior cast to any possessed by the writer of the following pages; yet after having given to this subject his best consideration—after the aid which he has derived from the works of the above-mentioned eminent writers—and after the valuable experience which a few late years, abounding in facts, have yielded to the present generation—it will not, he trusts, be deemed presumptuous in him to state his opinions on the laws of profits and wages, and on the operation of taxes. If the principles which he deems correct should be found to be so, it will be for others more able than himself to trace them to all their important consequences.
The writer, in combating received opinions, has found it necessary to advert more particularly to those passages in the writings of Adam Smith from which he sees reason to differ; but he hopes it will not on that account be suspected that he does not, in common with all those who acknowledge the importance of the science of Political Economy, participate in the admiration which the profound work of this celebrated author so justly excites.
The same remark may be applied to the excellent works of M. Say, who not only was the first, or among the first, of continental writers, who justly appreciated and applied the principles of Smith, and who has done more than all other continental writers taken together, to recommend the principles of that enlightened and beneficial system to the nations of Europe; but who has succeeded in placing the science in a more logical, and more instructive order; and has enriched it by several discussions, original, accurate, and profound.1 The respect, however, which the author entertains for the writings of this gentleman, has not prevented him from commenting with that freedom which he thinks the interests of science require, on such passages of the "Economie Politique," as appeared at variance with his own ideas.
CHAPTER I.
ON VALUE.
It has been observed by Adam Smith, that "the word Value has two different meanings, and sometimes expresses the utility of some particular object, and sometimes the power of purchasing other goods which the possession of that object conveys. The one may be called value in use; the other, value in exchange. The things," he continues, "which have the greatest value in use, have frequently little or no value in exchange; and, on the contrary, those which have the greatest value in exchange, have little or no value in use." Water and air are abundantly useful; they are indeed indispensable to existence, yet, under ordinary circumstances, nothing can be obtained in exchange for them. Gold, on the contrary, though of little use compared with air or water, will exchange for a great quantity of other goods.
Utility then is not the measure of exchangeable value, although it is absolutely essential to it. If a commodity were in no way useful—in other words, if it could in no way contribute to our gratification—it would be destitute of exchangeable value, however scarce it might be, or whatever quantity of labour might be necessary to procure it.
Possessing utility, commodities derive their exchangeable value from two sources: from their scarcity, and from the quantity of labour required to obtain them.
There are some commodities, the value of which is determined by their scarcity alone. No labour can increase the quantity of such goods, and therefore their value cannot be lowered by an increased supply. Some rare statues and pictures, scarce books and coins, wines of a peculiar quality, which can be made only from grapes grown on a particular soil, of which there is a very limited quantity, are all of this description. Their value is wholly independent of the quantity of labour originally necessary to produce them, and varies with the varying wealth and inclinations of those who are desirous to possess them.
These commodities, however, form a very small part of the mass of commodities daily exchanged in the market. By far the greatest part of those goods which are the objects of desire, are procured by labour; and they may be multiplied, not in one country alone, but in many, almost without any assignable limit, if we are disposed to bestow the labour necessary to obtain them.
In speaking then of commodities, of their exchangeable value, and of the laws which regulate their relative prices, we mean always such commodities only as can be increased in quantity by the exertion of human industry, and on the production of which competition operates without restraint.
In the early stages of society, the exchangeable value of these commodities, or the rule which determines how much of one shall be given in exchange for another, depends solely on the comparative quantity of labour expended on each.
"The real price of every thing," says Adam Smith, "what every thing really costs to the man who wants to acquire it, is the toil and trouble of acquiring it. What every thing is really worth to the man who has acquired it, and who wants to dispose of it, or exchange it for something else, is the toil and trouble which it can save to himself, and which it can impose upon other people." "Labour was the first price—the original purchase-money that was paid for all things." Again, "in that early and rude state of society, which precedes both the accumulation of stock and the appropriation of land, the proportion between the quantities of labour necessary for acquiring different objects, seems to be the only circumstance which can afford any rule for exchanging them for one another.
