“And this, children, is what I shall teach you. How to be a tree. How to war for space …” “But trees don’t move,” another said. “They move,” the Pragma replied, “but they are slow. A tree’s heart beats but once every spring, so it must war in all directions at once. It must branch and branch until it obscures the sky. But you, your hearts beat many, many times, you need only war in one direction at a time. This is how men seize space.”
