Capital, according as it is employed, is divided into fixed capital and circulating capital. Fixed capital may be used many times in production by its owner; circulating capital only once. The value of the latter kind of capital passes wholly into the value of the new product. In the case of the former kind of capital, only the value of its use passes into the new product. (_Hermann._) Hence, the farmer’s beasts of burthen belong to his fixed capital; their food, and his cattle intended for the slaughter, to his circulating capital. In a manufactory of machines, a boiler intended for sale is circulating capital; while a similar one, held in reserve for the machines used in production, is fixed capital. Ricardo attributes a somewhat different meaning to these two terms: he calls fixed capital that which is slowly consumed, and circulating, that which disappears rapidly.(287) Fixed capital is, indeed, produced and preserved by circulating capital; but it is, for the most part, transformed again into circulating capital.(288) Besides, it is only by means of the latter, that the former can be productively employed.(289) The relative importance of fixed and circulating capital to a country depends upon whether the country is an advanced or only an advancing one. A people with very much and very fixed capital are indeed very rich; but run the risk of offering many vulnerable points to an aggressive enemy, and of thus turning the easily jeopardized mammon into an idol. To make a passing sacrifice of the country that the people and the state may be saved, as did the Scythians against Darius, the Athenians against Xerxes, and the Russians against Napoleon, becomes difficult, in proportion as the nation has become richer in fixed capital.(290) But, as the destination of the latter is changed with much greater difficulty than that of circulating capital, highly cultivated nations would find it very hard to satisfy new wants, if they could not always appropriate the results of additional savings to the production of new fixed capital.
