This paper argues that Calvinist monism fails not only as a metaphysical and theological framework but as an honest intellectual project. It is structurally designed to be unfalsifiable, to insulate authority from accountability, and to reward closed interpretive control rather than genuine inquiry. The paper further argues that its appeal is partly psychological: it offers certainty, control, and immunity from correction while refusing serious contact with logic, mathematics, physics, and geometry as structured features of creation. The conclusion is that a serious ontology must remain open to correction, capable of explanation across domains, and accountable to reality rather than jargon.
