Nobody says that matter does not exist. That would be denying simple
facts. The point is that matter has phenomenological existence.
I thing we should never use the term ‘exist” without making precise if
we talk about ontological existence, or phenomenological existence.
Right. And that of course also applies to "non-existence". And
ontologies are theory dependent. To often the theory is assumed
implicitly and "exist" is use equivocally.
With mechanism there are eight important different notion of
phenomenological existence, and one simple notion of ontological
existence valid only for numbers.
And that "ontological existence" is in the context of the theory of
countable things, i.e. the natural numbers.
