nonexistences
States of nothing
Nonexistences is the plural of nonexistence, referring to multiple instances or types of absence or failure to exist.
The word appears in philosophical discussions where different kinds of nonbeing are distinguished: The nonexistences of unicorns and square circles differ—one is merely factual, the other logically necessary.
