Demarcation Guillotine

A sharp separation between “science” and “non‑science,” used to dismiss entire fields or practices as illegitimate. It draws a clean line based on a single criterion (e.g., falsifiability, empiricism, peer review) and then uses that line to exclude anything that doesn’t fit. The Demarcation Guillotine ignores the messy, contested history of demarcation and the fact that many legitimate disciplines (history, mathematics, design) don’t meet strict criteria. It is a favourite tool of scientistic debaters who want to purge “pseudoscience” without engaging with its content.
Example: “He declared that psychoanalysis was unscientific because it wasn’t falsifiable, and therefore worthless. The demarcation guillotine: one swing of the criterion, and an entire tradition is decapitated.”

Demarcation Domination

The power to draw and enforce boundaries between “science” and “non‑science,” “knowledge” and “belief,” “rational” and “irrational.” Those who control the demarcation criteria control which fields receive funding, which voices are heard in public debate, and which worldviews are pathologised. Demarcation domination is often wielded by institutional science against alternative medicine, indigenous knowledge, or critical social science. It is a form of epistemic gatekeeping that preserves the authority of dominant paradigms.
Example: “The funding agency refused to consider research on traditional healing because it fell outside their demarcation of ‘biomedical science.’ Demarcation domination: cutting off whole domains of inquiry.”

Science Domination

The broad exercise of power through science as a social institution: its authority to define truth, its influence on policy, its control over funding and publication, and its ability to marginalise non‑scientific ways of knowing. Science domination is not conspiracy but structure: scientific experts hold privileged positions in government, media, and education, and their claims are rarely questioned by the public. This domination can be benign (e.g., public health) but also oppressive (e.g., eugenics, race science). Understanding science domination is crucial for democratic oversight.

Example: “Economists, not citizens, set the parameters of national budgets. Science domination: expert authority replacing democratic deliberation.”

Demarcation Hegemony

The cultural dominance of a particular boundary between science and non‑science, to the point where that boundary is accepted as natural and eternal. Demarcation hegemony determines what counts as “real science” in public discourse, what gets funded, what children learn in schools. It shapes the public understanding of science and dismisses alternative epistemic traditions as “pseudoscience” or “religion.” Under demarcation hegemony, the act of drawing the line itself is rarely questioned.
Example: “In popular culture, astrology is automatically ‘pseudoscience’ while economics is ‘science’—demarcation hegemony, where the boundary is inherited, not examined.”

Science Hegemony

The cultural, political, and ideological dominance of science as the ultimate arbiter of truth, value, and reality. Under science hegemony, any claim that cannot be validated by scientific methods is considered lesser: mere opinion, belief, or superstition. Science hegemony permeates media, education, and government, often invisibly. It is not that science is wrong, but that its dominance forecloses other ways of knowing. Science hegemony is the background condition for scientism, the science guillotine, and the various other guillotines and dominations.

Example: “The philosophy department was defunded because ‘science answers everything.’ Science hegemony: reducing the university to the laboratory.”

Demarcation Pataphysics

A playful field that draws arbitrary and absurd boundaries between science and non‑science, then treats them with utmost seriousness. For example, declaring that only research conducted on Tuesdays counts as “science,” or that peer review requires the approval of at least three unicorns. Demarcation pataphysics exposes the contingency of real demarcation criteria by showing how easily they can be replaced with equally arbitrary rules. It is a weapon against scientific gatekeeping.
Example: “He proposed that any paper citing itself more than ten times should be reclassified as ‘pseudoscience.’ Demarcation pataphysics: mocking the line‑drawers by drawing a different line.”

Science Pataphysics

The pataphysical study of imaginary sciences, scientific theories that are internally consistent but refer to nothing real, and the social rituals of science performed as if their objects existed. Science pataphysics includes invented disciplines like “drainology” (the study of drains), “gnomonistics” (the art of sundial reading), and “unbecoming” (the study of things that never happen). It is a loving critique of science, celebrating its creativity while mocking its pretensions to final truth.

Example: “His science pataphysics lecture on ‘cryptopterology’ (the study of missing wings) used all the trappings of real science: abstracts, citations, graphs. The subject was entirely invented.”

Demarcation Metaphysics

A philosophical project that seeks a single, necessary and sufficient criterion to separate science from non‑science once and for all. Demarcation metaphysics assumes that the boundary is real, fixed, and discoverable, rather than a human convention that shifts over time. It drives the search for “the” demarcation criterion (falsifiability, problem‑solving, research programme) that has repeatedly failed. Demarcation metaphysics is an impossible quest that distracts from more productive discussions about knowledge and its evaluation.
Example: “His paper proposed a new demarcation criterion, the fifth this decade. Demarcation metaphysics: the endless search for a perfect line that doesn’t exist.”

Metaphysics of Science

A branch of philosophy that examines the fundamental assumptions and entities of science: what are laws of nature? What is causation? Do unobservable entities exist? It is a legitimate and important field. However, when the metaphysics of science is treated as the only legitimate ontology, it can become a form of hegemony, dismissing other metaphysical systems (e.g., process philosophy, hylomorphism) as unscientific. Used critically, it illuminates; used dogmatically, it excludes.

Example: “He argued that only particles are real, dismissing the reality of fields as ‘mathematical fiction.’ The metaphysics of science, turned into dogma.”

Reality Demarcation Problem

The philosophical and practical difficulty of cleanly separating "base reality" from the many conceptual, digital, or subjective layers we live within. It's the problem of pinpointing where the shared, objective physical world ends and where human constructions—like nations, economies, or social media reputations—begin. Since we experience everything through the filter of consciousness and culture, any line we draw is itself a constructed concept. Is a border wall "real"? The concrete is, but the political meaning enforcing it is a constructed layer on top. The problem shows that "reality" isn't a single tier, but a tangled hierarchy of things that have tangible consequences.
Example: "Arguing with a flat-earther, I hit the Reality Demarcation Problem. I cited satellite photos. He said they're CGI by a global cabal. I was appealing to a consensus reality built by science; he was appealing to a counter-reality built by conspiracy. There was no shared foundation to even start the debate. The 'real world' wasn't a fixed stage; it was the prize in the argument."

Objectivity Demarcation Problem

The core challenge in science and philosophy: how to distinguish an objective claim (true independent of observers) from a subjective one (dependent on a point of view). Since all observation is theory-laden and filtered through human senses and instruments, pure objectivity might be an impossible ideal. The "problem" is that every method we create to ensure objectivity (double-blind trials, peer review) is itself a socially constructed process. We demarcate the objective as that which survives these constructed filters, but the line is always provisional.
Example: "Two scientists saw the same data curve. One called it random noise; the other, a significant signal. The Objectivity Demarcation Problem is that their prior beliefs—their subjective 'priors'—dictated where they drew the line. Their argument wasn't about the data, but about where to place the demarcation between objective pattern and subjective illusion. Even statistics, our tool for objectivity, requires a subjective choice: the p-value threshold."
