I also take it as granted that every created thing, and consequently the created monad also, is subject to change, and indeed that this change is continual in each one.
Now where there are no parts, there neither extension, nor shape, nor divisibility is possible. And these monads are the true atoms of nature and, in a word, the elements of things.
