The level of set > the level of members, or their absence, for example:
The level the outer "{" and "}" is 0 and it is > than no level at all (nothing).
This reasoning is equivalent to the difference between nothing and a point, where a point is
something at the level of 0-dimensianal space.
A Ur-element is something at level 0 > no level at all (nothing).
According to my reasoning the outer "{" and "}" is the set level, where this level is above members' membership.
As a result no amount of members is accessible to the set's level that, by definition, is above members' membership.
Given {...{{{}}}}...} expression, no amount of members' levels ...{{{}}}... is is accessible to the set's level (where the set's level is notated by the outer "{" and "}" of the expression {...{{{}}}}...}.
According to this reasoning, no set is its own member, and we are able to distinguish between the actual (the set's level) and the potential (the members level).
The
actual level of a set is above the
potential level of members, no matter if the amount of members' levels is finite or infinite.
In such a framework contradiction is impossible, simply because contradiction is derived only from things on the same level.
Moreover, infinitesimals are the distinct signature of the inaccessibility of the members' level into the set level (as seen in the case of {...{{{}}}...} expression).
Negative numbers have nothing to do with cardinality (in the case of standard reasoning) or with levels (in the case of my non-standard reasoning), where is both cases < or > are used.
Since my non-standard reasoning of levels is equivalent the levels among dimensional spaces (where the term "dimensional spaces" is not restricted to Geometry or metric-spaces), an expression like {...{{{}}}...} asserts that ...{{{}}}... is the inaccessibility of any amount (amount of levels, in this case) to the outer "{" and "}" level of {...{{{}}}...} expression.
In terms of dimensional spaces, the outer "{" and "}" level of {...{{{}}}...} expression is irreducible into the ..{{{}}}... infinitely many levels, and the ..{{{}}}... infinitely many levels are non-extensible (inaccessible) to the outer "{" and "}" level.
An example of this non-standard reasoning (in terms of dimensional spaces, not restricted to Geometry or metric-spaces) is given in
