Something contingent here.
The concept of existence Becomesrelevant issue here.
The consciessness which makes meaning manifest in
this context, brings the patent theory of meaning to the fore, thereby ‘existence’ gains meaning.
Which brings to the fore the the idea of 0 as symbolic of nothingness. A nothingness which has a double value: a conceptual nothingness, and a functional nothingness.
How does this relate to consciousness of the void qua nothingness, as a lack of existence?
The significance of this train of thought lies in another difference, but one which subsumed the former, vis: conscience as a self differentiating function, or as a pre-existing field of possibility.
In the later case, the field or whatever you designate it, ‘exists’ prior, not in the temporal sense, of course,
but in the sense of a a shift away from a quantifiable difference.
This difference is evident in the sharp difference in the awareness of human beings away from animals.
The quanta(fiability) has changed the quality of awareness to a high degree and has progressed to the awareness of the in-it’s self, as a probable field.
In this sense, the idea of 0 , as nothingness, has gained a material substance.
You can divide by this, but it is always self consuming, and always results with the same result, = 1. It is the most basic logical equation, the law of identity.
