Consensus isn't just about agreement. It's about changing things around: You get a proposal, you work something out, people foresee problems, you do creative synthesis. At the end of it, you come up with something that everyone thinks is okay. Most people like it, and nobody hates it.
David GraeberNow, we're used to thinking of communism as being once-upon-a-time-all-things-were-owned-in-common, maybe-someday-this-will-come-again. And people agree that there is a sort of epic narrative going on here. I think we should just throw this narrative out, it's irrelevant anyway, and who cares who owns things? I don't. You know, we all own the White House. So what? I still can't go in, right?
David GraeberWithin a capitalist corporation, someone says, "Lend me a wrench," and someone asks, "Yeah, what do I get?" You assume that the idea of each according to his or her abilities, each according to his or her needs - in solving a problem - is actually the only thing that works. And in situations of disaster, there are often communistic notions of improvisation, where you basically exchange hierarchies and all of a sudden all those things that are luxuries that you can't afford, you have them in an emergency.
