The fundamental error of modern scientists is that they limit their investigations to the physical and palpable, while we have demonstrable evidence of the existence of the spiritual and invisible. We know nothing of matter but from its properties and manifestations, and we have the same kind of evidence in regard to spirit, and know that it is superior to gross matter, and therefore cannot be tested by the same crucibles. In the very nature of things a great cause must ever be imponderable and invisible. It cannot be weighed and measured, but must ever remain intangible and incomprehensible. The spirit in physical man in its relation to the Supreme Spirit is as the drop of water to the ocean or the single glimmering ray to the full-orbed, refulgent sun. Men may talk of “force correlation," and trace its progress and products, but they must remain dumb as to the beginning or origin of force unless they accept the doctrine of an _intelligent First Force_. There is no way of accounting for the existence of spirit, of life, of intelligence, but by premising the prior existence of spirit, life, and intelligence. Like only causes like. An egg does not come from a stone, and the ascidian did not come from a lifeless rock. The logical conclusion from the facts and principles herein suggested is that there must be an intelligent First Cause of all things—an all-pervading, fecundating, animating Spirit of the universe; and we prefer to call this God. Science has taught us the processes of his work, and denominates them the “laws of Nature.” In point of fact, as little is known of the origin and essence of matter as of spirit, and there is as good ground for agnosticism in the former as in the latter. There is therefore no necessary conflict between true science and a rational theism or monism. It is a rational proposition that something must have been before what is called creation. There must have been an _intelligent potency_, and that power theists call God. Materialism in its last analysis ascribes to matter all that theists ascribe to God. It gives matter an eternal self-existence—endows it with an inherent infinite intelligence and an omnipotent potency. It spells “God” with six letters instead of three. It makes a God of matter, and then denies his existence!
