 chemistry the absolute atomic weights of separate elements is unknown to us. But we know them relatively when we know their mutual conditions. And just as the production of commodities and their economy has a relative expression for the unknown quantities of labor existing in commodities, since it compares these commodities according to the relative amounts of labor which they contain, so chemistry makes a relative expression for the amounts of atomic weights unknown to it, since it compares the separate elements according to their atomic weights and expresses the weight of the one as multiples or factors of the other. And just as the production of commodities elevates gold to the position of an absolute commodity, to the universal equivalent for other commodities, the measure of values, so chemistry elevates hydrogen to the position of a chemical gold-commodity, since it fixes the atomic weight of hydrogen at 1 and reduces the atomic weights of all the other elements in terms of hydrogen and expresses them as multiples of its atomic weight.

The production of commodities is by no means the exclusive form of social production. In the ancient Indian communities and the family communities of the Southern Slavs products were not transformed into commodities. The members of the community were directly engaged in social production, the work was distributed as custom and circumstances required as were the products as they came into the realm of consumption. Direct social production and direct social consumption exclude all exchange of commodities and hence the transformation of products into commodities (at least within the confines of the society) and therewith their transformation into value.

As soon as society comes into direct possession of the
