ETHICS AND ONTOLOGICAL GROUNDING IN MODERN AND POSTMODERN PHILOSOPHY: A Critical Survey of Foundational Authorities

Abstract Contemporary scholarship remains marked by epistemic fragmentation arising from the absence of principled mechanisms for adjudicating truth claims across disciplinary domains. While postmodern critique successfully dismantled naïve foundationalism, it failed to provide a reconstructive architecture capable of governing knowledge without reduction or relativism. The Metadisciplinary Knowledge System (MKS©-Thronaxis) is proposed as a post-postmodern architectonic designed to address this governance failure. This paper articulates the architectonic foundations of MKS©-Thronaxis and formalises its model of epistemic governance, grounded in four mutually implicating pillars: Thronaxis Cosmology (ontological grounding), Hierarchical Epistemology (cognitive ordering), Synthesism (philosophical coherence), and Empirical Metadisciplinary Theology (methodological integration). It argues that genuine integration requires vertical ordering rather than horizontal aggregation, differentiated authority rather than epistemic flattening, and revelatory ontology rather than methodological eclecticism. Functioning as a Phase Two consolidation text within the MKS®-Thronaxis research program, this paper stabilises terminology, clarifies governance mechanisms, and positions MKS©- Thronaxis as a coherent post-critical architectonic for knowledge after postmodernism.
