Leibniz's Worlds The Connection between the Best Possible World and the Monadic Realm

In this paper I claim that in Leibniz s metaphysics, we can use the notion of world in a twofold sense; on the one hand to refer to highly complex divine thoughts, i.e. the ideal realm, and on the other hand to refer to a network of living substances with their perceptions and appetitions, i.e. the substantial realm. Firstly, I will clarify the ideal realm in Leibniz's metaphysics, which consists of three combinatorial levels about the fundamental entities, namely the simple ideas in God's mind complex ideas, complete individual notions and possible worlds. The second part is about the individual substances, i.e. the monads. In the third section, finally, I will discuss different ways to think about the connection between the ideal and the monadic world.
