But capitalism did require already existing institutions and organizing mechanisms. Trade, profit, ownership, commodities, price, all existed before "Capitalism". What existing institutions will fill out into its ism to replace that?
Not many people living before the era of capitalist dominance would have foreseen those institutions and mechanisms becoming vehicles of capitalist revolution, though. They only appear as such in hindsight.
That said, it's an area worthy of consideration. Paul Mason's recentish book
Postcapitalism explores the possibility that groupsourcing, peer-to-peer networks, wikis, and the like, all prefigure, if not socialism, then something that will exceed and replace capitalism. I can't say I agree with all of his conclusions- there are moments when it feels less like an advance over Marx than a retreat to Proudhon, and overall I think there's a preoccupation with the novel and the digital- and overall it's framed less like a resolution than a sort of sideways stumbling (although, given Mason's politics, I suspect this was as much as anything else a concession to the Fabian politics of the average left-wing Briton). Whatever one's politics, though, there are certainly some interesting ideas that bear exploration.
I mean we can disagree what is and what isn't communism all day long, but anyone who says 1970s Poland wasn't a communist country has 0 credibility on the subject
I'd hazard that Trotsky or Bordiga probably had a
little credibility on the subject.
Human nature is not just social - humans are basically pack animals. We're territorial, competitive, and hierarchical.
You can argue that humans are territorial and competitive, but you'd have a very difficult time arguing that humans are naturally hierarchical. Very few simple societies exhibit hierarchical tendencies, and many are actively anti-hierarchical. Hierarchy, real and enduring hierarchy rather than simple inequality of status, emerges falteringly, takes millennia to become entrenched, and centuries more to begin seriously penetrating the workings of everyday life.
Hierarchy is in fact a mess of contradiction. Effective hierarchy depends on there being sufficient social and economic complexity to make themselves necessary, but the greater the complexity, the less effective any one hierarchy becomes. The hierarchy peasant-baron-king is effective because it is simple and direct, because each rung has a clear position in the relation to the others, but ineffective because it supports only a very basic division of labour, so it struggles to exert itself over the business of daily and is easily toppled by those on the lower wrongs. The more complexity that is introduced- sheriffs and stewards and magistrates and monasteries- the more more stable and penetrative hierarchies can becomes, but the less effective any
one hierarchy becomes, the less clear and direct the relationships between any of the participants becomes, and the less authority any one person can bring against any other. Authority becomes less and less a characteristic of people and more of institutions.
The historical tendency is not towards the domination of humans by hierarchy so much as towards the domination of humans by institutions, towards a certain perverse equality, in which nobody has any power because all important decisions are made by impersonal institutions. That does not reflect any fundamental human nature, rather, it reflects the exhaustion of human nature, the failure of humanity's hardwired programming to keep pace with an ever-increasing social complexity.
