Immanence Without Exterior: Admissibility Regimes, the Operator δ , and Recursio Intensitatis

This manuscript rewrites a familiar Deleuzian demand into an operatorial constraint: immanence is not a thesis about what exists, but a discipline governing how existence becomes admissible without appeal to an exterior axis. The guiding problem is sharpened by a transdisciplinary reading of Deleuze’s conception of immanence as requiring a mechanism (a working machine) that maintains the articulation of two inseparable facets without collapsing them into either representational tracing or idealist conditioning. Here the plane of immanence is reconstructed as a membrane of admissibility regimes. The operator δ∗ is introduced as a threshold-shifter on this membrane, and Recursio Intensitatis (RI) as the cyclic process that reconfigures availability while keeping the system strictly interior, i.e., without invoking time or space as priors. The outcome is a practical philosophy: immanence becomes testable by failures, not celebrated by slogans.
