Chapter 1: The Commodity

Socially necessary labour-time is the labour-time required to produce any use-value under the conditions of production normal for a given society and with the average degree of skill and intensity of labour prevalent in that society. The introduction of power-looms into England, for example, probably reduced by one half the labour required to convert a given quantity of yarn into woven fabric. In order to do-this, the English hand-loom weaver in fact needed the same amount of labour-time as before; but the product of his individual hour of labour now only representect half an hour of social labour, and consequently fell to one half its former value.
