When you define the system this broadly, it takes on a more spiritually suggestive cast. The technological part of cultural evolution has relentlessly expanded social organization, leading us from isolated hunter-gatherer villages all the way to the brink of a truly global society. And the continuing cohesion of this social system (also known as world peace) may depend on people everywhere using their moral equipment with growing wisdom — critically reflecting on their moral intuitions, and on the way they’re naturally deployed, and refining that deployment.
Clearly, this evolutionary narrative could fit into a theology with some classic elements: a divinely imparted purpose that involves a struggle toward the good, a struggle that even leads to a kind of climax of history. Such a theology could actually abet the good, increase the chances of a happy ending. A more evolved religion could do what religion has often done in the past: use an awe-inspiring story to foster social cohesion — except this time on a global scale.
