ontological

Etymology

ontology + -ical

adj

1. Of or relating to ontology.
   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. 1948, W.v.O. Quine, On What There Is
2. Of or pertaining to the nature of being or existence.
   Such is the human ontological imagination, and such is the convincingness of what it brings to birth. Unpicturable beings are realized, and realized with an intensity almost like that of an hallucination. 1902, William James, The Varieties of Religious Experience, Lecture 3
