But in fact, because all motion is relative, we cannot distinguish between the hypothesis that the earth goes round the sun and the hypothesis that the sun goes round the earth. The two are merely different ways of describing the same occurrence, like saying that A marries B or that B marries A. ... We say that a train travels to Edinburgh, rather than that Edinburgh travels to the train. We could say the latter without intellectual error, but we should have to suppose that all the towns and fields along the line suddenly took to rushing southward, and that this extends to everything on the earth except the train, which is logically possible but unnecessarily complicated.
