Capital, also, is a social relation of production. It is a bourgeois production
relation, a production relation of bourgeois society. Are not the means of
subsistence, the instruments of labour, the raw materials of which capital con-
sists, produced and accumulated under given social conditions, in definite
social relations? Are they not utilized for new production under given social conditions, in definite social relations? And is it not just this definite social
character which turns the products serving for new production into capital?

Capital consists not only of means of subsistence, instruments of labour, and
raw materials, not only of material products; it consists just as much of
exchange values. All the products of which it consists are commodities. Capital
is, therefore, not only a sum of material products; it is a sum of commodities, of
exchange values, of social magnitudes.
