Since now every monad, as shut up within itself, has no influence upon the body and its movements, and yet the infinite multitude of their atoms correspond with one another, Leibnitz places this harmony in God; a better definition of the relation and the activity of the Monad of monads is therefore that it is what pre-establishes harmony in the changes of the monads.[270] God is the sufficient reason, the cause of this correspondence; He has so arranged the multitude of atoms that the original changes which are developed within one monad correspond with the changes of the others. The pre-established harmony is to be thought of somewhat in this style; when a dog gets a beating, the pain develops itself in him, in like fashion the beating develops itself in itself, and so does the person who administers the beating: their determinations all correspond with one another, and that not by means of their objective connection, since each is independent.[271] The principle of the harmony among the monads does not consequently belong to them, but it is in God, who for that very reason is the Monad of monads, their absolute unity. We saw from the beginning how Leibnitz arrived at this conception. Each monad is really possessed of the power of representation, and is as such a representation of the universe, therefore implicitly the totality of the whole world. But at the same time this representation is not in consciousness; the naked monad is implicitly the universe, and difference is the development of this totality in it.[272] What develops itself therein is at the same time in harmony with all other developments; all is one harmony. “In the universe all things are closely knit together, they are in one piece, like an ocean: the slightest movement transmits its influence far and wide all around.”[273] From a single grain of sand, Leibnitz holds, the whole universe might be comprehended in its entire development—if we only knew the sand grain thoroughly. There is not really much in all this, though it sounds very fine; for the rest of the universe is considerably more than a grain of sand, well though we knew it, and considerably different therefrom. To say that its essence is the universe is mere empty talk: for the fact is that the universe as essence is not the universe. To the sand grain much must be added which is not present; and since thought adds more than all the grains of sand that exist, the universe and its development may in this way certainly be comprehended. Thus according to Leibnitz every monad has or is the representation of the entire universe, which is the same as saying that it is really representation in general; but at the same time it is a determinate representation, by means of which it comes to be this particular monad, therefore it is representation according to its particular situation and circumstances.[274]
