The end of my inquiry is to try to clarify the relations between physics, metaphysics and mathematics in Leibniz’s case. This is not an easy task and much ink of pertinent Leibniz scholars was spread for its clarification. Although my analysis will focus mainly on the relation between physics and metaphysics in Leibniz-Clarke correspondence, yet, the other two fields, theology and mathematics will not be neglected, as well as previous works of Leibniz or of his contemporaries, which will be also targets of my analysis. Basically, there are three2 main alternatives:
1. Leibniz’s metaphysics derives from his logic;3
2. Leibniz’s metaphysics derives from his physics;4
3. Leibniz’s metaphysics is not grounded in anything else and, on the contrary, offers a fundamental basis for shaping and understanding the other two domains.

My position concerning these points of views is to defend the last, and thus to say that Leibniz metaphysical inquiry shapes the other domains and not the vice versa.
