What is a Hole?


Details
The question is quite simple, but the answer is quite tricky: What is a hole?
The question on what a hole is and whether it exists begin the dialogue between Argle and Bargle as they grapple with the challenging questions, like: What is the nature of holes? Are they material? Are they mere absence? Not quite, because there has to a be a perforated object for a hole to form, right? Maybe, or maybe not. And so it goes.
This will be a free discussion in light of David and Stephanie Lewis challenge to materialist ontology. The conversation will focus on defining holes, but also the troubling nature holes prose for materialist inclinations towards ontology.

What are Holes? (Metaphysics) (Video Lecture over the topic)
‘A hole?’ the rock chewer grunted. ‘No, not a hole’, said the will-o’-the-wisp despairingly. ‘A hole, after all, is something. This is nothing at all’.—Ende (1979/1983: 19)
