money, with the circulation of mere tokens of value. The fact which impresses him most is the depreciation of paper currency accompanied by the rise of prices of commodities. What the American mines had been to Hume, the paper-bill presses in Threadneedle street were to Ricardo, and he himself expressly identifies the two factors at some place in his works. His first writings, which dealt exclusively with the money question belong to the time of the most violent controversy between the Bank of England, which had on its side the ministers and the war party, and its opponents about whom were centered the parliamentary opposition, the Whigs and the Peace party. They appeared as immediate forerunners of the famous Report of the Bullion Committee of 1810, in which Ricardo’s views were adopted.[133] The singular circumstance, that Ricardo and his adherents, who held money to be merely a token of value, are called bullionists, is due not only to the name of that committee, but also to the nature of their theory. In his work on political economy, Ricardo repeated and developed further the same views, but nowhere has he investigated the nature of money as such, as he had done in the case of exchange value, profit, rent, etc. To begin with, Ricardo determines the value of gold and silver, like that of all other commodities, by the quantity of labor-time embodied in them.[134] By means of them, as commodities of a given value, the values of all other commodities are measured.[135] The volume of the circulating medium in a country is determined by the value of the unit of measure of money on the one hand, and by the sum total of the exchange values of commodities, on the other. This quantity is modified by economy in the method of payment.[136] Since the quantity of money, of a given value, which can be absorbed by circulation, is thus determined and since the value of money within the sphere of circulation manifests itself only in its quantity, it follows that mere tokens of value, if issued in proportions determined by the value of money, may replace it in circulation, and in fact, “a currency is in its most perfect state when it consists wholly of paper money, but of paper money of an equal value with the gold which it professes to represent.”[137] So far Ricardo determines the volume of the circulating medium by the prices of commodities, assuming the value of money to be given; money as a token of value means with him a token of a definite quantity of gold and not a mere worthless representative of commodities as was the case with Hume.
