The twentieth century did not merely criticize metaphysics; it dismantled its foundations. When Martin Heidegger exposed the structure of onto-theology, he revealed that Western metaphysics had long conflated Being with a highest being, thereby transforming ontology into theology. His retrieval of the ontological difference—between Being and beings—redefined the task of philosophy. Being could no longer function as ground, substance, or supreme presence. It withdrew even as it granted disclosure.
This transformation imposed a new discipline upon thought. Ontology became inseparable from finitude. The clearing replaced metaphysical architecture. Temporality—ecstatic, historical, and bounded by mortality—became the horizon of intelligibility. The sacred, if it remained, could no longer be articulated as a metaphysical foundation. It lingered at the margins of language, guarded by reticence.
Yet this discipline raises a further question: does the end of metaphysics require the flattening of manifestation? If being must not be objectified, must ontology remain structurally horizontal? Is finitude the ultimate and exhaustive horizon of disclosure?
It is precisely at this juncture that Henry Corbin becomes philosophically significant.
Corbin, whose early engagement with Heidegger decisively shaped his intellectual formation, did not reject the ontological difference. Nor did he seek to restore classical metaphysical hierarchy. Instead, through his retrieval of Islamic visionary philosophy—particularly the concept of the mundus imaginalis—he articulated what may be called a vertical differentiation of manifestation.
The imaginal, in Corbin’s usage, does not denote fantasy or subjective projection. It names a mode of being irreducible to both sensory empiricism and abstract conceptuality. Through angelology, symbolic mediation, and archetypal presence, Corbin proposed a grammar of manifestation that appears, at first glance, to challenge Heidegger’s austerity. Angels, graded presence, vertical temporality—such language risks reinstating hierarchy and foundation.
The philosophical question, however, is not whether Corbin employs religious vocabulary. It is whether his articulation reintroduces metaphysical grounding.
My book, Henry Corbin and Martin Heidegger: From Phenomenology to Angelology, examines this tension in detail. It reconstructs Heidegger’s ontology with conceptual precision—clearing, ontological difference, ecstatic temporality, and finitude as closure—before turning to Corbin’s imaginal expansion. The aim is not comparative theology nor intellectual biography, but ontological analysis.
Can the imaginal function as a differentiated manifestation without collapsing into a metaphysical hierarchy?
Can angelology be understood as a structure of mediation rather than a cosmological system?
Can temporality admit vertical articulation without dissolving the ontological difference?
These are not theological questions. They are structural ones. They concern the grammar of ontology after the end of metaphysics.
Heidegger safeguards thought by narrowing its articulation. Corbin tests whether articulation can occur without regression. The divergence between them is not simply opposition. It may represent two complementary fidelities: fidelity to the non-objectifiable character of Being, and fidelity to the depth of manifestation.
To think beyond finitude is not to deny finitude. It is to ask whether finitude exhausts the structure of manifestation. The risk of expansion is regression into a metaphysical foundation. The risk of restraint is the reduction of ontological depth. The future of post-metaphysical ontology may depend on sustaining this tension rather than resolving it prematurely.
This book argues that the movement from phenomenology to angelology is neither betrayal nor simple continuation. It is an ontological translation—a shift in the grammar of manifestation. Whether that translation ultimately succeeds remains open, but its philosophical stakes are considerable.
The question of Being did not end with metaphysics. It became more fragile and perhaps more demanding.
