Abstract
This chapter outlines a novel solution to the problem of the many, according to which objects can be simultaneously constituted by many collections of particles. To support this proposal, it develops a conception of objects that implies it. On this view, objects are fundamentally subjects of change: the changes an object can survive are explanatorily prior to its constitution. From this perspective, PM arises, and objects are multiply constituted because the changes that objects survive are too coarse-grained to distinguish among the many different collections of particles that are candidates for constituting the relevant object.
