How many angels can be in the same place at the same time? A defense of mereological universalism

Abstract

I reply to Hawthorne and Uzquiano's (2011) arguments for the incompatibility between mereological universalism and plenitudinous co-location. I argue that a mereology in which antisymmetry for parthood fails is independently motivated, and allows for both universalism and plenitudinous co-location. There can be as many angels in a place as there are cardinalities.
