Fundamentalist Evidentialism
A rigid, uncompromising form of evidentialism that treats any belief not supported by “proper” scientific evidence as not merely unjustified but immoral. It dismisses intuition, tradition, and personal experience as worthless, and it insists that evidential standards are universal and absolute. It is fundamentalist because it converts a methodological principle into an ethical absolute.
Fundamentalist Evidentialism Example: “He said that believing in love without a double‑blind study was ‘epistemically irresponsible.’ Fundamentalist evidentialism: measuring the heart with the tools of the lab.”
Fundamentalist Physicalism
A dogmatic physicalism that treats the non‑existence of the non‑physical as an a priori certainty rather than a working hypothesis. It rejects any evidence of mental causation or top‑down causality as impossible by definition, and it dismisses philosophical zombies and the hard problem as “language games.” It is fundamentalist in its refusal to examine its own metaphysical assumptions.
Example: “He insisted that consciousness is ‘obviously’ just brain activity, and that the hard problem is a ‘pseudoproblem.’ Fundamentalist physicalism: solving mysteries by denying they exist.”
Fundamentalist Reductionism
A thoroughgoing reductionism that treats explanation at higher levels as at best a convenience and at worst a deception. It holds that only the most fundamental level (e.g., particle physics) is real, and that all other sciences are mere shadows. It is fundamentalist in its zeal to eliminate levels, ignoring the successful autonomy of chemistry, biology, and psychology.
Example: “He claimed that ‘ultimately’ only quarks are real, and that tables and chairs are ‘illusions.’ Fundamentalist reductionism: sawing off the branch you’re sitting on.”
