Jean Grondin’s endeavor to revive metaphysics in a “post-metaphysical” age resonates with the ramifications of Cheng’s onto-generative hermeneutics for Western philosophy. However, Cheng also pinpoints that Grondin’s underdeveloped understanding of the cosmological source of creativity undermines his aims. To resolve this dilemma, Grondin’s claim that Gadamer rejects the source of metaphysical light in Plato is reassessed based on 1) Heidegger’s rethinking of existence as the Daoist Fourfold and 2) a reinterpretation of “the Good beyond Being”. Rather than a boundary to understanding, for Cheng, “beyond Being” signals an existential encounter with the Daoist void. In this way, the light in Grondin’s metaphysical hermeneutics surfaces from the ground up in Cheng’s cosmo-ontology.
