I develop ontological pluralism about non-being, the view that there are multiple ways, kinds, or modes of non-being. I suggest that the view is both more plausible and defensible than it first seems, and that it has many useful applications across a wide variety of metaphysical and explanatory problems. After drawing out the relationship between pluralism about being and pluralism about non-being, I discuss quantificational strategies for the pluralist about non-being. I examine historical precedent for the view. Finally, I suggest (...) that pluralism about non-being has explanatory power across a variety of domains, and that the view can account for differences between nonexistent past and future times, between omissions and absences, and between different kinds of fictional objects.
