The following basic propositions are essential for an understanding of the determination of exchange-value by labour-time. Labour is reduced to simple labour, labour, so to speak, without any qualitative attributes; labour which creates exchange-value [...] is specifically social labour; finally, labour in so far as its results are use-values is distinct from labour in so far as its results are exchange-values.

"Different use-values are, moreover, products of the activity of different individuals and therefore the result of individually different kinds of labour. But as exchange-values they represent the same homogeneous labour, i.e., labour in which the individual characteristics of the workers are obliterated. Labour which creates exchange-value is thus abstract general labour."

"Quite irrespective, therefore, of their natural form of existence, and without regard to the specific character of the needs they satisfy as use-values, commodities in definite quantities are congruent, they take one another’s place in the exchange process, are regarded as equivalents, and despite their motley appearance have a common denominator."
