Kierkegaard, the Danish philosopher, told a story about a goose who was wounded and who landed in a barnyard with some chickens. He played with the chickens and ate with the chickens. After a while that goose thought he was a chicken. One day a flight of geese came over, migrating to their home. They gave a honk up there in the sky, and he heard it.

Kierkegaard said, "Something stirred within the breast of this goose. Something called him to the skies. He began to flap the wings he hadn't used, and he rose a few feet into the air. Then he stopped, and he settled back again into the mud of the barnyard. He heard the cry, but he settled for less."
