Third: The market price of commodities either falls below or rises above its exchange value with the changing relations of supply and demand. Therefore, the exchange value of commodities is determined by the relation of supply and demand and not by the labor-time contained in them. As a matter of fact, this queer conclusion merely amounts to the question, how a market price based on exchange value can deviate from that exchange value; or, better still, how does the law of exchange value assert itself only in its antithesis? This problem is solved in the theory of competition.
Fourth: The last and apparently the most striking objection, if not raised in the usual form of queer examples: If exchange value is nothing but mere labor-time time contained in commodities, how can commodities which contain no labor possess exchange-value, or in other words, whence the exchange value of mere forces of nature? This problem is solved in the theory of rent.
CHAPTER II.
MONEY OR SIMPLE CIRCULATION.
In a parliamentary debate on Sir Robert Peel’s Bank Act of 1844 and 1845, Gladstone remarked that not even love has made so many fools of men as the pondering over the nature of money. He spoke of Britons to Britons. The Dutch, on the contrary, who, from times of yore, have had, Petty’s doubts notwithstanding, “angelical wits” for money speculation have never lost their wits in speculations about money.
The main difficulty in the analysis of money is overcome as soon as the evolution of money from commodity is understood. This point once granted, it only remains to comprehend clearly the particular forms of money, which is to some extent made difficult by the fact that all bourgeois relations, being gilt or silver plated, have the appearance of money relations, and money, therefore, seems to possess an endless variety of forms, which have nothing in common with it.
In the following investigation only those forms of money are treated of which directly grow out of the exchange of commodities; the forms which belong to a higher stage of production, as e. g., credit money will not be discussed here. For the sake of simplicity gold is assumed throughout as the money commodity.
1. THE MEASURE OF VALUE.
The first process of circulation constitutes, so to say, the theoretical preparatory process to actual circulation. To begin with, commodities which are use-values by nature, acquire a form in which they appear in idea to each other as exchange values, as definite quantities of incorporated universal labor-time. The first necessary step in this process is, as we have seen, the setting apart by the commodities of a specific commodity, say gold, as the direct incarnation of universal labor-time, or the universal equivalent. Let us go back for a moment to the form in which commodities turn gold into money.
