3. THE PRE-ESTABLISHED HARMONY.—The universe is thus the sum of all the monads. Every thing, every composite, is an aggregate of monads. Thus every bodily organism is not one substance, but many, it is a multiplicity of monads, like a machine which is made up of a number of distinct pieces of mechanism. Leibnitz compared bodies to a fish-pond, which might be full of living elements, though dead itself. The ordinary view of things is thus wholly set aside; the truly substantial does not belong to bodies, _i. e._ to the aggregates, but to their original elements. Matter, in the vulgar sense, as something conceived to be without mind, does not at all exist. How now must the inner connection of the universe be conceived? In the following way. Every monad is a representative being, and at the same time, each one is different from every other. This difference, therefore, depends alone upon the difference of representation: there are just as many different degrees of representation as there are monads, and these degrees may be fixed according to some of their prominent stages. The representations may be classified according to the distinction between confused and distinct knowledge. Hence a monad of the lowest rank (a monad _toute nue_) will be one which _simply_ represents, _i. e._ which stands on the stage of most confused knowledge. Leibnitz compares this state with a swoon, or with our condition in a dreamy sleep, in which we are not without representations, (notions)—for otherwise we could have none when awaking—but in which the representations are so numerous that they neutralize each other and do not come into the consciousness. This is the stage of inorganic nature. In a higher rank are those monads in which the representation is active as a formative vital force, though still without consciousness. This is the stage of the vegetable world. Still higher ascends the life of the monad when it attains to sensation and memory, as is the case in the animal kingdom. The lower monads may be said to sleep, and the brute monads to dream. When still farther the soul rises to reason or reflection, we call it mind, spirit.—The distinction of the monads from each other is, therefore, this, that each one, though mirroring the whole and the same universe in itself, does it from a different point of view, and, therefore, differently, the one more, and the rest less perfectly. Each one is a different centre of the world which it mirrors. Each one contains the whole universe, the whole infinity within itself, and in this respect is like God, the only difference being that God knows every thing with perfect distinctness, while the monad represents it confusedly, though one monad may represent it more confusedly than another. The limitation of a monad does not, therefore, consist in its containing less than another or than God, but only in its containing more imperfectly or in its representing less
