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.
1 ton of iron = 2 ounces of gold
1 quarter of wheat = 1 ounce of gold
1 hundred weight of Mocca coffee = 1-1/4 ounce of gold
1 hundred weight of potash = 1/2 ounce of gold
1 ton of Brazil timber = 1-1/2 ounces of gold
Y commodities = X ounces of gold
In the above series of equations iron, wheat, coffee, potash, etc. appear to each other as embodiments, of homogeneous labor, namely, as labor materialized in money, from which all the peculiarities of the different kinds of concrete labor represented in the different use-values are completely eliminated. As value they are all identical, they are the incarnation of the same labor, or the same incarnation of labor, viz., gold. As uniform embodiments of the same labor they display only one difference, a quantitative one, by appearing as different quantities of value, because unequal quantities of labor-time are contained in their use-values. The mutual relation of these separate commodities is that of embodiments of universal labor-time, since they are related to universal labor-time as to an excluded commodity, viz., gold. The same relation the development of which causes commodities to appear to each other as exchange values, causes the labor time contained in gold to appear as universal labor-time, a given quantity of which is expressed in different quantities of iron, wheat, coffee, etc,—in short, in the use-values of all
