Re: [ontolog-forum] entity: nothing

["Peter F Brown" <peter@xxxxxxxxxx>]

A hole is not the same as a “nothing” – there are two separate threads in this discussion: are we not talking about two different “things” (I use the word advisedly and very cautiously)?

Hi Paola -

The Cage analogy came around to silence being able to be bounded by sound. Carved sculptures take away unwanted material until only the essential parts remain. In museum design certain content is not ready to be named but it can be classified, subject areas yet to be defined are left as blank, un-labeled placeholders allocating space, hoping future requirements will fit without rearranging everything again.

More to your point surely is John's statement "more like a boundary than pure nothingness". So with the stretched metaphors above.....What do you think needs to be bounded? What are opposite each other inside and outside the boundaries? What could possibly be consistent across a range of ontologies? What existing communication system like OWL, or ___, or ___, or ___ is best suited to indicating a boundary? How do you know when you encounter a boundary? Simply won't process? How do you "see" the holes and can you measure how big or small they are?

Following the discussion on holes, the one questrion that I am left
with is  whether
holes are entities as such, or non entities  and

if so
whether they would belong to a  ' class of nothing' being
proposed/discussed somewhere earlier on this forum

It looks to me that they are non entity cause they dont have a mass
that can be measured
I mean an entity is determined by its attributes and properties while
the only property of a hole that we can say is 'absence of energy'

This is an attempt to bring the hole discussion into the focus of
current ontological question

apologies if this is trivial
