When God works miracles, he does not do it in order to supply the wants of nature, but those of grace. Whoever thinks otherwise, must needs have a very mean notion of the wisdom and power of God.

There is no way in which a simple substance could begin in the course of nature, since it cannot be formed by means of compounding.

But in simple substances the influence of one monad over another is ideal only.

Now this connection or adaption of all created things with each, and of each with all the rest, means that each simple substance has relations which express all the others, and that consequently it is a perpetual living mirror of the universe.

And there must be simple substances, because there are compounds; for the compound is nothing but a collection or aggregatum of simples.

Every present state of a simple substance is the natural consequence of its preceding state, in such a way that its present is big with its future.

Every mind has a horizon in respect to its present intellectual capacity but not in respect to its future intellectual capacity.
