If the two men we have supposed wished to obtain the satisfaction of their wants, without acting in concert, each would labour to provide for himself both the articles wanted. If they came to an understanding, the one would provide coal for two from the coal-mine, the other ice for two from the mountain. This presupposes a bargain. They must then adjust the relation of the two services exchanged. They would take all circumstances into account—the difficulties to be overcome, the dangers to be braved, the time to be spent, the pains to be taken, the skill to be displayed, the risks to be run, the possibility of providing for their wants in some other way, etc., etc. When they came to an understanding, the Economist would say, The two ‹services› exchanged ‹are worth› each other. In common language, it would be said by metonymy—Such a quantity of coal ‹is worth› such a quantity of ice, as if the value had passed physically into these bodies. But it is easy to see that if the common form of expression enables us to state the results, the scientific expression alone reveals to us the true causes. In place of two services and two persons, the agreement may embrace a greater number, substituting a complex Exchange for simple Barter. In that case, money would intervene to facilitate the exchange. Need I say that the principle of value would be neither changed nor displaced? But I must add here a single observation ‹àpropos› of coal. It may be that there is only one coal-mine in a country, and that an individual has got possession of it. If so, this man will make conditions; that is to say, he will put a high price upon his ‹services›, or pretended ‹services›. We have not yet come to the question of right and justice, to the distinction between true and loyal services, and those that are fraudulent and pretended. What concerns us at this moment is, to consolidate the true theory of value, and to disembarrass it of one error with which Economical science is infected. When we say that what nature has done or given, she has done or given ‹gratuitously›, and that the notion of ‹value› is excluded, we are answered by an analysis of the price of coal, or some other natural product. It is acknowledged, indeed, that the greater part of this [p145] price is the remuneration of the services of man. One man has excavated the ground, another has drained away the water, another has raised the fuel to the surface, another has transported it to its destination; and it is the aggregate of these works, it is allowed, which constitutes ‹nearly› the entire ‹value›. Still there remains one portion of the ‹value› which does not correspond with any labour or ‹service›. This is the value of the coal as it lies under the soil, still virgin, and untouched by human labour. It forms the share of the proprietor; and, since this portion of Value is not of human creation, it follows necessarily that it is the creation of nature.
