Ain't Nature Grand

I've finally come up with a kind of unified field theory of human behavior, explaining why we just cannot and never will get our act together as a successful species, like say, cockroaches. Mankind is doomed by our conflicting impulses, on the one hand noble, on the other selfish. Both are evolved survival strategies, but to keep them in balance we need institutions, like churches and government, and institutions have a tendency to devolve into the opposite of what they were originally meant for. And there you have all of history in a nutshell.
