A curious thing about the ontological problem is its simplicity. It can be put in three Anglo-Saxon monosyllables: "What is there?" It can be answered, moreover, in a word -"Everything" - and everyone will accept this answer as true. However, this is merely to say that there is what there is. There remains room for disagreement over cases.
