Abstract
Material Plenitude is the view that there is an abundance of coincident objects wherever there is any material object. Although plenitude has garnered increased attention from metaphysicians in recent years, it has yet to be well‐understood beyond its slogan from. The goal of this article is to explore a few places for puzzlement about plenitude; in particular, how we ought to motivate and formulate the target view. I'll suggest along the way that an investigation of plenitude is not merely of interest in its own right, but can provide valuable insights into abundant ontologies more generally.
