A dogmatic metaphysical stance that only matter (its particles, forces, and interactions) is real, and that any appeal to mind, meaning, or value independent of matter is delusion. The materialist fanatic dismisses consciousness as mere epiphenomenon, free will as illusion, and morality as evolutionary by‑product. They treat scientific materialism as proven truth, ignoring that materialism itself is a philosophical assumption, not a finding of science. Materialist fanaticism often appears in online atheist and rationalist communities, where any hint of non‑materialist thinking is met with ridicule.
