“If then we leave out of consideration the use value of commodities, they have only one common property left, that of being products of labor. But even the product of labor itself has undergone a change in our hands. If we make abstraction from its use value, we make abstraction at the same time from the material elements and shapes that make the product a use value; we see in it no longer a table, a house, yarn, or any other useful thing. Its existence as a material thing is put out of sight. Neither can it any longer be regarded as the product of the labor of the joiner, the mason, the spinner, or of any other definite kind of productive labor. Along with the useful qualities of the products themselves, we put out of sight both the useful character of the various kinds of labor embodied in them, and the concrete forms of that labor; there is nothing left but what is common to them all; all are reduced to one and the same sort of labor, human labor in the abstract” (Marx and Engels 1975-2004, vol. 35, p. 48).
By abstracting from specific kinds of labor, we do not create a new kind of labor. Abstract labor and its products do not exist in themselves; they are found in concrete labor processes and their products. But if concrete labor creates use values and commodities, then abstract labor creates exchange values and money. As we have shown, use value is not an individual utility but a socially necessary set of existence values. Use value is, so to speak, a prologue to a commodity in demand on the market and its exchange value. For a commodity to have an exchange value it should have a use value, that is, satisfy socially necessary needs. Commodities are wealth because they accumulate both use and exchange values.
We will distinguish between the multiplicity and the mass of meanings. The multiplicity of meanings consists of a set of meanings. In terms of commodities, these could be: two rolls of cloth, three bulls, ten tons of steel, etc. The mass of meanings is the set of cultural bits contained in a given multiplicity of meanings. Concrete labor creates commodities, abstract labor defines their mass. As Marx said, the abstract labor that forms the substance of value is homogeneous labor. However, since at the time of Marx there was neither information theory nor the concept of the bit, he had to measure abstract labor in terms of labor time:
