 to replace the geometric difference between uniform and  accelerated motion with the dynamic difference between  guidance and force. Opponents of Einstein asked the question:  Since the church tower receives a jolt in its motion relative to the  train just as the train receives a jolt in its motion relative to the church tower, why does the train become a wreckage and not the church tower which it passes? Common sense would answer: because the train  is ripped out of the pathway of the guiding field, but the church  tower is not. … As long as one ignores the guiding field one  can neither speak of absolute nor of relative motion; only if one  gives due consideration to the guiding field does the concept of  motion acquire content. The theory of relativity, correctly  understood, does not eliminate absolute motion in favour of relative  motion, rather it eliminates the kinematic concept of motion and  replaces it with a dynamic one. The worldview for which Galileo  fought is not undermined by it [relativity]; to the contrary, it is  more concretely interpreted.
