Bounding is an act: excluding what lies beyond the self-sustaining relational unit.
Given that the coherence of the self-sustaining relational unit is determined by its need to distinguish itself from what it is not, it cannot not derive a dynamic of determination: Bounding. This is the act that enacts the exclusion of what lies beyond the relational unit — relationlessness.
The derivation has seen exclusion before: Excluding was the original act of setting aside what lies outside the something’s identity. Bounding enacts the same logic at the level of the whole self-sustaining unit. What lies beyond the unit’s boundary is not merely “something else” but the absence of relation — the non-relational.
Bounding produces Distinction (the condition maintaining the division between relation and non-relation) and ultimately Boundary (the structure stabilizing that division).
