but that their value depends not on their utility, not on the degree in which they are desired, but on the quantity of labour necessary to procure them." "The utility of a commodity thus understood, makes it an object of man's desire, makes him wish for it, and establishes a demand for it. When to obtain a thing, it is sufficient to desire it, it may be considered as an article of natural wealth, given to man in an unlimited quantity, and which he enjoys, without purchasing it by any sacrifice; such are the air, water, the light of the sun. If he obtained in this manner all the objects of his wants and desires, he would be infinitely rich: he would be in want of nothing. But unfortunately this is not the case; the greater part of the things which are convenient and agreeable to him, as well as those which are indispensably necessary in the social state, for which man seems to be specifically formed, are not given to him gratuitously; they could only exist by the exertion of certain labour, the employment of a certain capital, and, in many cases, by the use of land. These are obstacles in the way of gratuitous enjoyment; obstacles from which result a real expense of production; because we are obliged to pay for the assistance of these agents of production." "It is only when this utility has thus been communicated to a thing (viz. by industry, capital, and land,) that it is a production, and that it has a value. It is its utility which is the foundation of the demand for it, but the sacrifices, and the charges necessary to obtain it, or in other words, its price, limits the extent of this demand."
The confusion which arises from confounding the terms "value" and "riches" will best be seen in the following passages.4 His pupil observes: "You have said, besides, that the riches of a society were composed of the sum total of the values which it possessed; it appears to me to follow, that the fall of one production, of stockings for example, by diminishing the sum total of the value belonging to the society, diminishes the mass of its riches;" to which the following answer is given: "the sum of the society's riches will not fall on that account. Two pair of stockings are produced instead of one; and two pair at three francs, are equally valuable with one
