The Ontology of Finitude: Foundations for Credible Theological Grammar

This paper challenges the Western philosophical and theological tradition’s subordination of finitude to the infinite, arguing instead for finitude as the positive ontological foundation of human existence and credible theological discourse. Drawing primarily on Emmanuel Falque’s critique of “the pre-emption of the infinite” and Jan Patočka’s concept of “being shaken,” the study demonstrates how finitude constitutes not a limitation to be overcome but the necessary horizon within which any authentic encounter with transcendence must occur. The argument proceeds through four stages: deconstructing the Cartesian legacy that privileges the infinite over the finite; establishing phenomenological reorientation toward “impassable immanence;” introducing “being shaken” as the existential manifestation of finitude; and addressing critiques of this approach. The paper argues that Christianity’s incarnational logic—particularly Christ’s assumption of human finitude—provides theological validation for this phenomenological insight. The central contribution lies in proposing “credible theology”—theological discourse that derives legitimacy not from abstract rationality but from fidelity to the common human condition of finitude. This approach offers a methodological alternative to traditional fundamental theology by grounding theological reflection in the shared structures of existence.
