Two good passages nicked from friends:
“Since men are, as physiological beings, directly entwined with nature, organs of its circulation process, what befalls all creatures befalls them; like all animals they die, and nothing comes thereafter, as Brecht puts it. If they wish to separate themselves off from nature as Subjects, they must tackle this problem in order to reproduce their life. They must work with nature, and negate it, and in all forms of society this means the sacrifice of pleasure, and self-denial. Whether man’s relation to nature is considered from the point of view of that of diversity, it is not possible to speak of an attempt to make nature metaphysical.”
and from a passage Bonefeld has clearly taken to heart:
Instead of dealing with the question of the material nature of the soul, which can have at times an idealist, that is to say a diversionary, function in society, even when the reply to it is a materialist one, Marxist materialism is primarily concerned with the possibility of removing hunger and misery from the world.’
Finally three additional points of importance for this work: I would say it also was (1) the first–or one of the first–works to use the Grundrisse (2) Was probably enormously influential on the philological method many Marxologists use today. (3) Got Adorno to further engage and ground his work in Marx’s thought.
