ABSTRACTHow did the traditional doctrine of parts and wholes evolve into contemporary formal mereology? This paper argues that a crucial missing link may lie in the early modern and especially Wolf...

The approach adopted by Early Modern authors to the notions of ‘whole’ and ‘part’ (what is called, in contemporary metaphysics, “mereology”, from the Ancient Greek word μερος: ‘part’) constitutes a central feature of their respective systems. The issue of what constituted a whole became all the more crucial as the new, revolutionary approaches to matter and extension – which mark the unavoidably fuzzy beginning of what we define as “modernity” – demanded a novel (and in some cases, radical) approach to (...) the questions of what constitutes a whole and how parts are arranged and bound together. It is important to mention that diverse attitudes towards mereology characterised Early Modern philosophers orthogonally to their belonging to different camps, such as the traditional categories of ‘Rationalists’ and ‘Empiricists’. Some of these philosophers considered wholes to be ontologically and/or logically prior to their parts (an approach that we may call “organicist” or “holist”, applying an anachronistic but nonetheless appropriate label). Others considered wholes to be derivative, resulting from the union of their parts (an approach that could be named “mereological mechanism”). Therefore, a word about terminology is in order: in what follows, I will apply the label “holist/organicist” to refer to a philosopher who would favour the priority of wholes over parts. Vice versa, I shall label as a “mereological mechanist” any philosopher favouring the priority of parts over the wholes formed by those parts, regardless of such parts being exclusively material, or including spiritual/mental parts as well as material ones.
