An expanded model adding two crucial dimensions to the basic framework. Axis 1: Materialism-Idealism (matter vs. mind). Axis 2: Monism-Pluralism (one vs. many). Axis 3: Realism-Antirealism (reality exists independently vs. reality depends on mind/language). Axis 4: Atomism-Holism (reality consists of fundamental parts vs. wholes are primary). These four axes create sixteen metaphysical positions. Scientific realism is materialist, pluralist (many particles), realist, atomist (particles fundamental). Quantum holism might be materialist, monist (field), realist, holist (wholes primary). Idealism is idealist, could be monist or pluralist, could be realist (ideas independent) or antirealist (ideas depend on larger Mind). The 4 Axes reveal that metaphysical positions are defined by clusters of commitments.
The 4 Axes of the Spectrum of Metaphysics "You think you're just a realist. The 4 Axes ask: realist about what? Material or ideal? One or many? Atomist or holist? Scientific realism is very different from Platonic realism, even though both are realist. The axes show you what kind of realist you actually are—or whether you've even thought about it."
