It is tedious going over the arguments which reduce this mode of reasoning to an absurdity. The same reasoning has been applied to every important discovery in physical science for the past three hundred years; and if it were carried out to its logical conclusions no substantial advance in human knowledge could ever take place, since every discovery or observation of phenomena outside of known laws must on that ground be rejected. And the history of scientific discoveries shows that this has actually been the case. The announcement of the discovery of the movements of the planets around the sun, of the attraction of gravitation, of the identity of lightning with electricity, of the relation and derivation of species in the world of living forms--of the discovery of living toads in geological strata of untold antiquity, and scores of other now accepted facts, were accounted visionary and were received with scoffs and jeers by the accredited leaders of science, because they were outside of any known natural laws; and it was only after the study and contemplation of the new discoveries had educated and enlarged the minds of a new generation of men to a better understanding of the extent and magnitude of nature and her laws that the scoffs subsided and the new facts quietly took their places as accredited science. The same process is going on regarding mental phenomena to-day. It may require a generation for men unused to think in this direction to become familiarized with the thought that telepathy, clairvoyance, and the subliminal self, with its augmented powers, are facts in nature; but thousands of intelligent people, and many accustomed to examine facts critically and according to approved methods, are already so interpreting nature, and their number is constantly increasing.
