Structure

Why do we have this preference for all things structured? Is it that somewhere along the evolutionary chain we lost our sense of structure and so we are constantly forced to look for it and keep on reinventing what we’ve lost? There’s a sense of structure and predictability in the so-called non-rational world of animals. National Geographic will probably vouch for this. So, does that mean rational beings are compelled to articulate structures, build consensus, codify them, and make sure that everyone else is more or less following them because pure reason is rooted in non-structure?
