Live in the world like a waterfowl. The water clings to the bird, but the bird shakes it off. Live in the world like a mudfish. The fish lives in the mud, but its skin is always bright and shiny.
Every bird which flies has the thread of the infinite in its claw. Germination includes the hatching of a meteor and the tap of a swallow's bill breaking the egg, and it leads forward the birth of an earth-worm and the advent of Socrates.
You may call a jay a bird. Well, so he is, in a measure--because he's got feathers on him, and don't belong to no church, perhaps;but otherwise he is just as much a human as you be. And I'll tell you for why. A jay's gifts and instincts, and feelings, and interests, cover the whole ground. A jay hasn't got any more principle than a Congressman.
