William James told the story of a group of hunters in the forest. One of the men sees a squirrel on a tree, and the squirrel sees him. The squirrel scrambles to the opposite side of the tree from the man. The man circles the tree, and the squirrel cautiously stays on the opposite side of the tree from him, and around and around they go, The other hunters disagree. One says the man goes around the tree and the squirrel, and another objects that the man goes around the tree, but not the squirrel. They turn to James to get the opinion of a philosopher. "It's all a matter of defining your terms," James answers. "If by 'going around' you mean 'going east, south, west, north, east, etc.,' then the man certainly goes around the squirrel. But if by 'going around' you mean 'going from side to back to side to belly to side, etc.' then the man does not go around the squirrel."
