An ultra-fine-grained model adding dimensions of universals, particulars, and modality. Building on the 8 Axes, we add: Axis 9: Realism-Nominalism about Universals (universals like redness exist independently vs. only particulars exist). Axis 10: Actualism-Possibilism (only actual things exist vs. possibilities are real). Axis 11: Endurantism-Perdurantism (things persist wholly through time vs. things have temporal parts). Axis 12: Presentism-Eternalism (only present exists vs. past and future equally real). These twelve axes generate 4096 metaphysical positions. Platonism is idealist, pluralist (forms and particulars), realist about universals, possibilist (forms are possibilities), endurantist (forms are timeless), eternalist (all times equally real). The 12 Axes reveal that debates about time, universals, and possibility are all interconnected—your position on one constrains your options on others.
The 12 Axes of the Spectrum of Metaphysics "You think numbers are real. The 12 Axes ask: real as universals (Platonism) or real as mental constructions (conceptualism)? Real in all possible worlds or just actual? Timeless or temporal? Present or eternal? 'Numbers are real' is eight words; the axes turn it into twelve questions. That's not overcomplicating—that's precision."
