A good civilisation spreads over us freely like a tree, varying and yielding because it is alive. A bad civilisation stands up and sticks out above us like an umbrella-artificial, mathematical in shape; not merely universal, but uniform.
Heaven, in the production of things, is sure to be bountiful to them, according to their qualities. Hence the tree that is flourishing, it nourishes, while that which is ready to fall, it overthrows.
