Gottfried Leibniz Substance Quotations

And as every state of a simple substance is a natural consequence of its preceding state, so that the present state of it is big with the future.

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

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

The monad, of which we shall speak here, is nothing but a simple substance which enters into compounds; simple, that is to say, without parts.

Every substance is as a world apart, independent of everything else except God.

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.
