I have seen spirits whose earthly condition was one of grandeur, whose mortal life was one of study, experimentalism, achievement, and triumph,—scientists who gave their entire thought, time, and attention to the investigation of certain laws, elements, and forces of the physical world, and who made grand and important discoveries in the domain of Nature. Their demonstrations of scientific law have been of value to mankind; their achievements and the practical results of their discoveries and studies have benefited humanity. But certain ones of this learned body did not believe in the existence of any force or power outside of organic law,—would not accept the thought that any manifestation of human or divine intelligence, skill and wisdom, could possibly be made aside from matter, and declined to investigate any department of life outside of that particular field of scientific inquiry that chained their attention. Anything savoring of occult law, or denoting the existence of subtle forces in the universe, that physical science could not explain, they scoffed at as unworthy their thought and investigation. The condition of such spirits as these in the spiritual world is not an envious one. For a time they are unaware that they have left the material body. Dependent upon gross matter for their thought, study, labor, and research, they do not gravitate above the earth, and for awhile they continue their investigations and experiments in the laboratories of their former earthly associates.
