From this time on, its rate of rotation would diminish until it stopped. If its integrity were suddenly violated, this stop would come at once. Fifty years ago, heat, light, and electricity were all talked of, and believed to be forces whose existence was in no way dependent upon matter. Since the investigations of Thomson and Helmholtz, there is no unbiased scientist who can for a minute think that the manifestation of any of these could possibly exist without material of some sort, such as in a general way we call matter. Even chemism, the most obscure of all physical forces, we know to be very closely allied to gravitative attraction, and to be so powerful since it operates through such short distances. In fact, if we adopt the only known feasible hypothesis to account for the formation of matter, we must, in the end, admit that motion, and not matter, is the most potent of all the primal causes which we can imagine to-day. If we could eliminate motion entirely from the universe, we do not know of a single characteristic which would be left, by which we could identify existence as we know it, certainly not even matter itself. Every investigation or experiment which has been made in the domain of the natural sciences has only amassed additional evidence to the tremendous amount already gathered; all going certainly to prove that at least the former two of the old three universally accepted postulates were false, _viz._: the free moral agency of man, the immortality of the soul, and the existence of a personal God, or a power outside of and superior to nature. The latter will in no wise interest us, inasmuch as experience has taught us that, in general as well as in particular, the universe is governed by law; all honor to Humboldt and Descartes for so clearly demonstrating this.
