character to the hearts of all moral beings as the spiritual realm, and that in which He reveals His creative power to the minds of all intelligent beings as the natural realm.
If we do not distinguish these realms to start with, we invite confusion; and if we should reach right conclusions without this classification, it would be due to accident, rather than to scientific accuracy.
But that this classification is universally recognized is proved by the fact that the moment science reaches the line where the natural ends and the spiritual begins, it pursues its investigations no farther, on the ground that it has neither the implements nor the capacities with which to investigate in that realm. This proves as conclusively as anything could that the distinction between these two realms is so sharp, as well as so self-evident, that science is compelled to accept it and act accordingly.
2. The Faculties of Investigation Must be Distinguished.
The scientific man will next distinguish the faculties with which the investigating is to be done, according to the respective realms. That this classification is required by the fundamental difference in the nature of the truths in these two realms is so self-evident that it ought to be axiomatic to all who think with any degree of scientific accuracy. For in the nature of things, natural truth requires investigation by intellectual faculties, and spiritual truth by spiritual faculties. Indeed, this distinction is fully recognized when science halts its pursuit of truth at the boundary line of the spiritual realm.
