Chapter 8: Constant and Variable Capital

Page 317

That part of capital, therefore, which is turned into means of production, i.e. the raw material, the auxiliary material and the instruments of labour, does not undergo any quantitative alteration of value in the process of production. For this reason, I call it the constant part of capital, or: more briefly, constant capital.

On the other hand, that ·part of capital which is turned into labour-power does undergo an alteration of value in the process of production. It both reproduces the equivalent of its own value and produces an excess, a surplus-value, which may itself vary, and be more or less according to ·circumstances. This part of capital is continually being transformed from a constant into a variable magnitude. I therefore call it the variable part of capital, or more briefly, variable capital. The same elements of capital which, from the point of view of the labour process, can be distinguished respectively as the objective and subjective factors, as means of production and labour-power, can be distinguished, from the view of the valorization process, as constant and variable capital.
