2. THE MONADS MORE ACCURATELY DETERMINED.—The monads of Leibnitz are similar to atoms in their general features. Like these they are corpuscular units, independent of any external influence, and indestructible by any external power. But notwithstanding this similarity, there is an important and characteristic difference between the two. First, the atoms are not distinguished from each other, they are all qualitatively alike; but each one of the monads is different in quality from every other, every one is a peculiar world for itself, every one is different from every other. According to Leibnitz, there are no two things in the world which are exactly alike. Secondly, atoms can be considered as extended and divisible, but the monads are metaphysical points, and actually indivisible. Here, lest we should stumble at this proposition (for an aggregate of unextended monads can never give an extended world), we must take into consideration Leibnitz’s view of space, which, according to him, is not something real, but only confused, subjective representation. Thirdly, the monad is a representative being. With the atomists such a determination would amount to nothing, but with Leibnitz it has a very important part to play. According to him, in every monad, every other is reflected; every monad is a living mirror of the universe, and ideally contains the whole within itself as in a germ. In thus mirroring the world, however, the monad is not passive but spontaneously self-active: it does not receive the images which it mirrors, but produces them spontaneously itself, as the soul does a dream. In every monad, therefore, the all-seeing and all-knowing one might read every thing, even the future, since this is potentially contained in the present. Every monad is a kind of God.
