things have been grasped, analyzed, and, what is more, reproduced by the giant progress of science; and what we can produce, we certainly cannot consider as unknowable. To the chemistry of the first half of this century organic substances were such mysterious objects; now, we learn to build them up one after another from their chemical elements without the aid of organic processes. Modern chemists declare that as soon as the chemical constitution of no matter what body is known, it can be built up from its elements. We are still far from knowing the constitution of the highest organic substances, the albuminous bodies; but there is no reason why we should not, if only after centuries, arrive at that knowledge and, armed with it, produce artificial albumen. But if we arrive at that, we shall at the same time have produced organic life, for life, from its lowest to its highest forms, is but the normal mode of existence of albuminous bodies.
As soon, however, as our agnostic has made these formal mental reservations, he talks and acts as the rank materialist he at bottom is. He may say that, as far as we know, matter and motion, or as it is now called, energy, can neither be created nor destroyed, but that we have no proof of their not having been created at some time or other. But if you try to use this admission against him in any particular case, he will quickly put you out of court. If he admits the possibility of spiritualism in abstracto, he will have none of it in concreto. As far as we know and can know, he will tell you there is no Creator and no Ruler of the universe; as far as we are concerned, matter and energy can neither be
