"In this book, J'études the capitalist mode of production and the relations of production and exchange which correspond to it. [...] This is not the more or less complete development of the social antagonisms that the natural laws of capitalist production generate, but of these laws themselves, tendencies that manifest themselves and are realized with the necessity of iron. At first glance, the commodity appeared to us as something double-sided, use value and exchange value. Then we saw that all the characters that distinguish productive work from usage values disappear as soon as it is expressed in the value itself. I first highlighted this double character of the work represented in the commodity. [...] As long as it is bourgeois, that is, as long as it sees in capitalist order, not a transitional phase of historical progress, but the absolute and definitive form of social production, political economy can remain a science only if the class struggle remains latent or manifests itself only by isolated phenomena." Karl Marx.
