Dear Paola,

understand thanks
please note that I have not problem with the fact that observable reality is bounded by spatiotemporal continuum
just that some parts of reality are not observable
and yes, I can understany why an ontology would want to model the observable world, for practical reasons

[MW] The point is that things that are not considered observable are still spatio-temporal extents that are part of some spatio-temporal continuum, unless they are sets (according to 4D anyway). So it is not a matter of wanting only to model the observable world, it is about how things are understood to be.

Regards

Dear Paola,

Ontologies differ in the way they approach what you think of as intangibles. Some of them have specific things that would claim to be intangible, others do not.

For 4D ontologies like IDEAS and ISO 15926, everything is either a spatio-temporal extent (possible or actual) and sets (including relations).

So I will not talk for others, but I will say what the list below is from a 4D perspective.

I understand that most intangibles can be associated with a tangible countepart
even the wind, which we cannot touch, is indeed a physical phenomenon

however, things exist that are abstract, ie, do not have physical qualities
I can make a list but surely you can come up with a list too

emotions (okay, sweat and heartbeat are indicators of emotions but not emotions themselves)
ideas

[MW] This is usually some sort of plan of how things could be, so we are into possible worlds (or John's version of them)

Thoughts

[MW] Thinking is an activity that goes on in a spatio-temporal location, and a thought is presumably the result of this, and is a state of, perhaps part of, someone's brain.

Beliefs

[MW] Beliefs would usually be about rules that are followed. So the rules would be around some classes, and the belief part is about how someone views those rules.
