Now there is still another possibility: someone may not take the path we have tried to follow to the activities of the spiritual Hierarchies, but may still come to an acceptance of certain spiritual beings. The celebrated German philosopher, Leibnitz, was a man of this kind. Leibnitz had got beyond the prejudice that anything merely material can exist in the world. He found the actual, he sought the actual. (I have treated this more precisely in my book, The Riddles of Philosophy.) His view was that a being—as, for example, the human soul—can build up existence in itself. But he formed no further ideas on the subject. He only said to himself that there is such a being that can build up existence in itself, and force concepts outwards from within itself. For Leibnitz, this being is a “Monad‿. And he said to himself: “There must be many Monads, and Monads of
the most varied capabilities. If I had here a bell, there would be many monads in it—as in a swarm of midges—but they would be monads that had never come even so far as to have sleep-consciousness, monads that are almost unconscious, but which nevertheless develop the dimmest of concepts within themselves. There are monads that dream; there are monads that develop waking ideas within themselves; in short, there are monads of the most varied grades.‿
A person with this outlook does not come so far as to picture to himself the individual spiritual beings in concrete terms, as the Spiritist does, but he reflects in the world upon the spiritual element in the world, allowing it to remain indefinite. He calls it “Monad‿—that is, he conceives of it only as though one were to say: “Yes, there is spirit in the world and there are spirits, but I describe them only by saying, ‘They are entities having varying powers of perception.’ I pick out from them an abstract characteristic. So I form for myself this one-sided world-outlook, on behalf of which as much as can be said has been said by the highly intelligent Leibnitz. In this way I develop Monadism.‿ Monadism is an abstract Spiritism.
