Meta Ontology

In his book Persons and Objects, Professor Chisholm undertakes to show the satisfactoriness of an ontology which does not admit the existence of concrete events, such as sneezings, runnings, etc. He attempts to show that if we allow the existence of states of affairs, these being everlastingly existing entities, we need not acknowledge the existence of those perishing entities which are concrete events. I n this paper I discuss the tenability of this contention, considering especially whether the reductions that Chisholm offers cope satisfactorily with the phenomena of tense. I conclude that they do not. My conclusion is that, at this point in history, we do not know whether ontology can do without concrete events
