Fixed capital, considered as a means of production, whose most adequate form is machinery, only produces value (i.e. increases the value of the product) in two cases: (1) in so far as it has value, i.e. in so far as it is itself the product of labour, a definite quantity of labour in an objectified form; (2) in so far as it increases the proportion of surplus labour to necessary labour by making it possible for labour, by increasing its productivity, to create more quickly a larger amount of the products needed for the sustenance of living labour power. To say that the worker is in co-operation with the capitalist because the latter makes the worker’s labour easier by means of fixed capital, or shortens his labour, is a bourgeois phrase of the greatest absurdity. Fixed capital is in any case the product of labour, and is merely alien labour that has been appropriated by capital; and the capitalist could be said, rather, to be robbing labour of all its independent and attractive character by means of the machine. On the contrary, capital only uses machinery in so far as it enables the worker to devote more of his working time to the capitalist, to work longer for others and experience a larger part of his time as not belonging to him. Through this process, in fact, the quantity of labour necessary for the production of a particular object is reduced to a minimum, so that a maximum of labour can be valorized into the maximum number of such objects. The first aspect is important, because capital in this instance has quite unintentionally reduced human labour, the expenditure of energy, to a minimum. This will be to the advantage of emancipated labour, and is the condition of its emancipation.
