Elster said "[there] are no societies, only individuals who interact with each other" on page 248 of "The Cement of Society". This was cited in Marcus Roberts' book "Analytical Marxism: A Critique". I will try to track down the paragraphs in Elster where the sentence occurs and post them. Roberts' book is worth a look-see, but it has two problems. It was originally a PhD thesis and, because of this I suppose, is wordy and unclear. Moreover, Roberts' own politics are not that sharply defined so he is always invoking somebody else's expertise in refuting the AM'ers, such as Mandel, etc. If I ever wrote a book like this, I would use it as an opportunity to clarify basic Marxist concepts rather than nit-picking AM'ers, which is Roberts' tendency.
