There are moments when a rope's end, a pole, the branch of the tree, is life itself, and it is a frightful thing to see a living being lose his hold upon it, and fall like a ripe fruit.
And after we returned to the savannahs and abandoned the trees, did we long for those great graceful leaps and ecstatic moments of weightlessness in the shafts of sunlight of the forest roof?
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.
Creation destroys as it goes, throws down one tree for the rise of another. But ideal mankind would abolish death, multiply itself million upon million, rear up city upon city, save every parasite alive, until the accumulation of mere existence is swollen to a horror.
