Human civilization depends on cooperation, which can be obtained through numerous mechanisms -- everything from violent coercion to mutual aid to shared ideals.

Human civilization depends on cooperation, which can be obtained through numerous mechanisms -- everything from violent coercion to mutual aid to shared ideals. The more effective forms of cooperation depend on a shared imaginary space (culture). I especially appreciate what you've written about the danger of monopolization of this imaginary space. Today, we talk about "information bubbles", but it seems the effect is that we've simply carved up this imaginary space into little city states so that two people of the same age from the same town can disagree on who won the last presidential election.
