The winds and seas, the powers of water and earth an light, all that these do, and all that the beasts and green things do, is well done, and rightly done. All these act within the Equilibrium. From the hurricane and the great whale's sounding to the fall of a dry leaf and the gnat's flight, all they do is done within the balance of the whole. But we, insofar as we have power over the world and over one another, we must learn to do what the leaf and the whale and the wind do of their own nature. We must learn to keep the balance. Having intelligence, we must not act in ignorance. Having choice, we must not act without responsibility.
Ursula K. Le Guin, The Farthest Shore
