Hence, there has been, unfortunately, the great army of investigators and thinkers, in the realm of matter, studying its phenomena and laws, never approaching the threshold of the spiritual; and, on the other hand, the more important knowledge of spirit, of man’s future, which retrospects his present life and all past ages, and reaches into the infinite ages to come, was the especial care of those who scorned nature and abhorred reason. Hence the antagonism, which can only be removed by the priest laying aside his books as infallible authority, discarding beliefs, dogmas, and metaphysical word legerdemain, and studying the inner world in the same manner that the outer has been so advantageously explored. When this has been done, it may be found that physical investigators have not the whole truth, even when they have been the most exact. It may be found that, having omitted the spiritual side in all their investigations, their conclusions are erroneous to the extent of that factor, which may be one of the most important. It may be found that in order to have a complete and perfect knowledge of the external world, the internal or spiritual must be understood. Here we face the time-old questions: What is matter? What is spirit? The philosophy of nature here rests. There is no middle ground. The materialist starts from the atom, which, he says, has in itself all the possibilities of the universe and outside of which there is nothing. THE ATOM.--But who knows of the atom, into which matter, at last analysis, is resolved? No one. Aside from the active forces which apparently flow from it, we know nothing, and speculation takes the place of knowledge. That speculation, unfettered by the requirements of accurate science, grew rankly in the minds of the sages of antiquity, and bore the strangest fruits. From that time to the present, speculative thought has not ceased in activity, nor arrived at any certain conclusion. The atomic theory is one of the most splendid generalizations in the whole circle of sciences. As a working hypothesis its aid is invaluable, and the solution it affords of the most intricate combination of the elements, truly marvelous. Yet it is a conjecture; the existence of the atom a guess. No one ever saw, tasted, or felt the atom. It is absolutely beyond the senses, as it is beyond any instrumental aid thereto. The entire structure of physical science, as expounded to-day, rests on conjecture, the only evidence in support of which is that it explains the phenomena. There is no assurance that other conjectures might not explain them quite as well. It would be a waste of time to explore this field, wherein the baseless dreams of philosophers and scientists have grown like Jonah’s gourd, over-shadowing the barren sands.
