I have previously repeated
some transcriptions from the correspondence Marx and Engels. I tried to concentrate on some formulations from
Engels of ideas important in Marxism, Marx stating what is important and novel in Capital, or
outlines of the project, particularly concentrating on the so-called transformation problem.
This long letter certainly belongs in this collection.
Marx’s ideas were fairly well-developed in 1858. Here he has promised Duncker, a publisher, to write
what eventually became A Contribution to the Critique of Political Economy.
After delay, he only delivered to the publisher the first part of what he was aiming for.
I have always found this short book less inspiring, as compared with Capital.
Capital does not contain anything on advocates of labor notes, though.
