Ex-centric Life: Helmuth Plessner and the Phenomenology of Positional Being

This paper reconstructs Helmuth Plessner’s concept of positionality as a phenomenological topology of life that dissolves the reflexive interiority presupposed by transcendental thought. Plessner defines the living being as a form that sustains itself at its boundary—in Grenze stehen—by mediating between inside and outside. Such positional being is neither self-enclosed nor purely exposed: it persists through the tension of its own limit. This ex-centric structure, in which the organism relates to itself from its boundary, constitutes a mode of structural exteriority that precedes both subjectivity and objectivity. Through a reading of Plessner alongside Fink and Merleau-Ponty, the paper develops an account of ex-centric life as the ontological condition of participation and as a model of self-maintenance without recursion.
