Abstract

In this paper I claim that in Leibniz’s metaphysics we can use the term ‘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. First of all, 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, fnally, I will discuss different ways to think about the connection between both worlds—how the best possible world is linked to the actual monadic world.
