Mereologia della sostanza e mereologia del vivente in Leibniz

Any study of Leibniz's mereology, i.e. his doctrine of the relationship between parts and wholes, involves at best engaging with concepts of strong polysemicity; in the end, such an inquiry could even be misleading. A mereological approach may require, in relation to Leibniz's thought, to consider very different objects, to which tools apply that are also significantly different. This paper will therefore deal with the question of Leibnizian mereology from a limited point of view: that of the different orders of composition and of the different relationships whole / parts that are found in Leibniz's thought, or that do not occur in it, and of the possible correspondence between them. The starting point will be his ideas on the composition of substances, from which different orders of parts and wholes ensue. This may be of help in solving certain problems that concern substances and substantiated entities, but mereological problems concerning the parts of living beings cannot be solved in this way.
