Principles of Political Economy

Now then, if Money be, as it is, a peculiar kind of Capital, since it is a Medium in all Exchanges, the question becomes pertinent, How much of it is wanted? Clearly, only so much as will serve the purposes which such a medium is fitted to subserve; there should be enough fairly to mediate between the Services actually ready to be exchanged then and there, and also enough fairly to call out other Services proper and profitable in the then circumstances of Society, and whose only obstacle to a profitable exchange then and there is a lack of a facilitating medium. All increase of the volume of money beyond this point, which the very nature of Money itself marks out as the boundary, leads to a diminution of Value of every part of it, to a consequent disturbance of all existing monetary contracts, to a universal rise of prices which are illusory and gainless, to unsteadiness and derangement in all legitimate business, and to a spirit of restless enterprise and speculation which seeks to draw off the excess of money in untried and reckless experiments. The only real subjects of Exchange are mutual efforts, mutual services, as these are expressed in Commodities and Services and Credits, and money is the instrument merely that comes in between the real exchanges to facilitate them; and, therefore, it seems to be perfectly conclusive on this point to remark that the quantity of money needed in any country or the whole world is limited by the number of the services ready to be exchanged, to make easy the exchange of which is the good purpose and sole end of Money.

The physical and mental powers of man, which alone can give birth to commercial services, when considered as they must be in this connection as belonging to a given number of men at a given time and place, are strictly limited of course; and although the presence of money then and there is both a stimulus and an aid to all these men to bring forward services of all sorts to the market, there are obvious restrictions both in their powers and in their circumstances; and the quantity of money needed among them is just that quantity which will fairly act as a medium in exchanging the services which they are able and willing to render to each other. All increase in the quantity of money beyond that point would have, and could have, the only effect of increasing the nominal Prices of Services, without making the services themselves any greater in number or better in quality.

It is with Money exactly as it is with any other form of Capital, allowance being made for the fact that Money is a kind of generalized capital. To illustrate, How many ships does a commercial nation need to employ? As many as will fairly take off its exports and bring in its imports. Ships are wanted for one definite purpose; and when enough are secured to answer that purpose, all additions will lessen the Value, that is, the purchasing-power, of ships generally. So of all instruments whatever. Enough is as good as a feast. Enough is better than more. In regard to every form of Capital, and consequently in regard to Money as such, the point of sufficiency is determined by the quantity of work to be done. And as no law of Congress is required to determine how many ships are best to do the transportation for the people of the United States, so no legislation is needed to fix the amount of Money that is best for the same people, or for any people. As the people find out for themselves how many steam-engines they want to do their work of the year, so they find out without any aid from their legislators how much money they want to make their exchanges of the year. The less Law and the more Liberty on all such points the better for all concerned.

Let the reader notice in passing, as a corollary from what has just been shown, that when forms of Credit like bank cheques come into growing use to make payments with and settle balances, they displace to a large extent commodity-moneys, like gold and silver, which would otherwise have to be employed. Speculations, and even scientific discussions, over the needful amounts of gold and silver for money in the United States, have usually overlooked this essential consideration of displacement; and one result of this has doubtless been too large a coinage of the precious metals, to the hazard of their stable value, and especially to the hazard of the permanent maintenance of the gold standard. Men forget in their zeal for Money that it is nothing but a Tool, and that the multiplication of tools beyond the amount of work to be done by means of them always makes the tools a drug; and they are apt to forget also that the cheaper and more convenient substitutes for metallic moneys, namely, forms of Credit, are all the time and more and more taking the place of the older moneys, which, nevertheless, must still be kept at the foundation, though a lessened quantity of them be needful for circulation.

6. We must now carefully sink our analysis one grade deeper, in order to reach the bottom characteristic of Money, and so to formulate an ultimate definition of it.

The only quality common to all valuable things is the fact that they are all salable; and if these various and multitudinous valuables are ever to be made in any way commensurable with each other, it must be by means of one of their number assumed as a standard of comparison with the rest. Comparisons can only turn on points of likeness. The single respect in which all valuables whatsoever resemble each other is their common possession of purchasing-power, be it more or less. Therefore, as a yardstick, itself possessed of length, and because it is possessed of length, if assumed as a standard of comparison with other objects that have length, may be used to measure all such objects whatsoever, and may accurately express in units or fractions of itself the simple length of anything and everything; so, any valuable may be selected as a standard with which to compare all other valuables, and by means of the terms of which to express numerically the reciprocal relations between all valuables whatsoever. This is just what is done whenever any valuable is selected as Money; and this is the exact and single purpose of such selection.

What is the precise change, then, in the valuable chosen as Money when it becomes money? This: it was a valuable before, else it could not by any possibility serve the present purpose, but now it has become a standard valuable, with which other valuable things may be compared in the single point of their value. Valuables are now commensurable. That is all. But that is a great deal. As we have already learned to the nail, Valuables are all Services; and now some one Service has been selected from the rest, capable in its very nature of measuring all the rest, and so capable of becoming immensely useful to mankind.

What, accordingly, is the bottom characteristic of Money? And where shall we find the terms for an immutable definition of it? The core of Money is this quality of being a Measure of Services, taken on in addition to the usual and universal qualities constituting anything a Valuable. This additional quality arises under the choices and action of men, just as the ordinary qualities constituting anything a valuable arise under the choices and action of men. But it is an additional quality, distinctly conferred, and vastly important. The valuable chosen as Money was a Service to start with, was constantly rendered as such then and there, and was consequently fitted by qualities already possessed to assume a further and a unique quality, namely, the capacity to measure and express relatively to itself all other valuable Services whatever.

As each and every Valuable is the outcome of a comparison instituted by two persons as between two things, as is thoroughly unfolded in the first Chapter, it is not at all strange, rather it is natural and inevitable, that there should arise in connection with Valuables as a whole class some such further comparative measure, as Money is now shown to be; because, without some such common measure of Services in general, itself a Service of the same kind, it would be inconvenient, not to say impossible, to carry on any considerable traffic anywhere. For instance: a baker has only loaves of bread, and wishes to buy a hat, a horse, a house. How many loaves shall he give for each? Unless there be some common Service, in the terms of which these differing Valuables can be expressed, and by means of which they can be brought into commercial relations with each other, it would be an awkward piece of business to effect even the three exchanges; and every time the baker wished to buy another article, there must be a rude and slow calculation from independent data, in order to decide upon the terms of the exchange. Let now some Common Service be introduced, in the terms of which each of these values can express itself independently, and the difficulty disappears in an instant. "My loaves are worth ten cents each," says the baker. "My hat is worth ten dollars," says the hatter. Their saying so does not indeed make it so; that matter is a preliminary; but each has come to that approximate conclusion by a relatively easy comparison of two Services, his own and another common one; and if the loaves will duly bring ten cents and the hat ten dollars, the terms of their own exchange are one hundred for one, and there is no need of parleying. So of the rest; so of everything that is ever bought and sold. Money becomes by common consent a Measure of them; because it measures them, it makes the interchange of them a very facile matter; because it measures them, it easily becomes a medium between them; and, accordingly, because the money rendered is itself a Service, it is a natural and universal measure of all other Services.

Money is a current and legal measure of services. With this final definition of "Money" the writer is more than willing to take all the risks. It was new when propounded many years ago in one of the editions of his earlier book. All subsequent testings of it in form and substance have but confirmed the original confidence in it. The word "legal" in this definition is not always to be pressed to its utmost signification, but denotes anything sanctioned by law or usage equivalent to law. The other words are to be taken in their full and technical meaning. It is believed that, while this definition is short and simple, it just covers the whole ground and no more. It is not enough that a certain valuable be "legal" as Money; it must also be "current" in order to be a true money. In the United States between 1862 and 1879, to take an example, gold coins, though legal tender all the time for all debts public and private, were not "current" in the full sense of that term, and hence were not the Money of the country. Till the last-mentioned date, the gold dollar of 25 ⁴⁄₅ grains standard fine was required by law to pay customs-taxes with and the interest on the public debt, and was used to a small extent in a few branches of private business, and was not otherwise in the hands of the people. These dollars, accordingly, were not strictly money, but bore a premium over the "current" money of the country. To be Money, then, a Valuable must be recognized as money by law or custom as strong as law, and also circulate among all classes of the people as a medium in their exchanges.
