cur aliquid potius extiterit quam nihil - Gottfried Wilhelm Leibniz

I don't really eliminate body, but reduce it to what it is. For I show that corporeal mass, which is thought to have something over and above simple substances, is not a substance, but a phenomenon resulting from simple substances, which alone have unity and absolute reality.

Et comme tout présent état d'une substance simple est naturellement une suite de son état précédent, tellement, que le présent y est gros de l'avenir.

Reality cannot be found except in One single source because of the interconnection of all things with one another.
