The Pretension of Exteriority: Referential Closure and the Jurisdiction of Articulation

Reality appears to be independent of its appearing: it resists, constrains, and persists regardless of attention. Imagination, by contrast, feels derivative and optional. This paper argues that the asymmetry, while phenomenologically real, cannot be ontologically grounded from within the practice that registers it. A survey of grounding accounts---causal, phenomenological, physicalist---reveals a shared presupposition: that reference to the grounding relation is independently settled. The paper formalizes referential closure---the condition under which all reference within a practice is internally stabilized---and proves a parity theorem: no consequence available within the practice distinguishes the hypothesis that reference is externally anchored from the hypothesis that it is closure-stabilized. The demand for ontological grounding exceeds referential jurisdiction. The paper then develops a positive structural account. An appearance hierarchy identifies structural aboutness as the constitutive floor for articulation; qualia are modeled as multi-plane stabilization patterns whose explanatory gap is invariant; and the reality/imagination distinction is explained as differential stabilization---high-constraint versus low-constraint---within referential closure. The framework does not claim exhaustiveness: the possibility of non-articulative being remains genuinely open. What is removed is the demand for ontological grounding---not because it is false, but because it exceeds the jurisdiction of the only adjudicative practice available.
