Long-Duration Motion Machines of the Second Kind (LDMM2)
Devices designed for extreme-duration motion by optimizing against the Second Law of Thermodynamics—not violating it, but approaching its limits asymptotically. The Second Law says entropy increases; LDMM2 fight entropy by creating near-perfect isolation from dissipative processes. They don't reverse entropy; they just slow its increase to a crawl. A supercooled ring levitating in vacuum, spinning for thousands of years—that's LDMM2. The energy gradually dissipates, but so slowly that human civilization could rise and fall while it's still spinning. LDMM2 are the thermodynamic equivalent of putting your leftovers in a freezer that lasts millennia: entropy still wins, but it takes its time.
Long-Duration Motion Machines of the Second Kind (LDMM2) "They've got gyroscopes in space that will spin for thousands of years before slowing down. That's LDMM2—not defying the Second Law, just making it work overtime. The universe still wins, but it has to wait. LDMM2 is what happens when engineers decide to play the long game against entropy itself."
Long-Duration Motion Machines of the First Kind (LDMM1)
A class of devices designed to maintain motion for extremely long periods—thousands of years or more—by optimizing energy storage and minimizing losses, while respecting the First Law of Thermodynamics (energy conservation). Unlike perpetual motion machines (which claim to violate physical laws), LDMM1 acknowledge that energy must come from somewhere; they just store it so efficiently that motion continues far beyond human timescales. Think of a flywheel in a perfect vacuum, on frictionless bearings, spinning for millennia on the energy you gave it once. LDMM1 don't create energy—they hoard it, releasing it so slowly that "long-duration" means geological time. They're possible because the First Law isn't violated; energy is conserved, just doled out over eons.
Long-Duration Motion Machines of the First Kind (LDMM1) "That clock they built in 1986 is still running on its original battery? It's not perpetual motion—it's just really, really efficient. That's LDMM1: store energy once, release it over centuries. Not magic, just engineering so good it looks like magic to anyone who's ever changed a smoke detector battery."
Theory of Reason Privilege
The broadest formulation: the claim that "reason" itself is a privileged category, constructed and deployed in ways that serve some interests while excluding others. Reason privilege operates when one group's way of knowing is treated as Reason itself, while others' ways are treated as mere opinion, belief, or emotion. Reason privilege is invisible to those who have it—they just think they're being reasonable. For those excluded, the privilege is painfully visible. Theory of Reason Privilege doesn't reject reason; it rejects the monopolization of reason, the use of reason as a tool of exclusion.
Theory of Reason Privilege "You say 'let's be reasonable' and expect everyone to agree. Theory of Reason Privilege says: your reason isn't everyone's. You've been trained in a particular tradition of reason; others have different traditions. Calling your tradition 'reason' and theirs 'culture' is privilege in action. Reason can be shared, but only when it's not owned. Your privilege is thinking your reason is the only one."

Theory of Rational Privilege
The critical claim that certain groups, practices, or traditions are granted "rationality" while others are denied it—that rationality is distributed unevenly along lines of power. Western science is rational; indigenous knowledge is "belief." White men are rational; women and people of color are "emotional." The powerful are rational; the powerless are "irrational." Theory of Rational Privilege exposes how rationality functions as a gatekeeping concept, conferring authority on some while denying it to others. Rationality isn't just a standard—it's a weapon.
Theory of Rational Privilege "He's called 'passionate' when he argues; she's called 'hysterical.' That's Rational Privilege—rationality distributed by gender. His passion is reason; her passion is pathology. Rationality isn't just about thinking; it's about who gets to be seen as a thinker. Theory of Rational Privilege asks: who gets rationality, who doesn't, and what power does that serve?"

Theory of Logical Privilege
The critical theory that certain logical systems are privileged—treated as universal, neutral, and authoritative—while others are marginalized, dismissed, or invisible. Western classical logic enjoys logical privilege: it's taught as logic itself, not as one logic among many. Indigenous logics, Eastern logics, feminist logics are treated as alternatives at best, deviations at worst. Theory of Logical Privilege exposes this hierarchy, asking who benefits when one logic is treated as the logic, and whose knowing is silenced when other logics are dismissed.
Theory of Logical Privilege "You keep saying 'that's not logical.' Theory of Logical Privilege asks: not logical by which logic? You're using classical Western logic as the standard, assuming it's universal. But other logics exist—relational, dialectical, fuzzy. Your privilege is invisible to you, but it's real. Logic isn't neutral when one logic gets to define what logic is."

Theory of Constructed Reason
Similar to Constructed Rationality but emphasizing reason as a process, a practice, a tradition—not a faculty but an activity, shaped by history, culture, and context. Reason is something we do, not something we have; it's constructed in communities of inquiry, passed down through education, modified by experience. Theory of Constructed Reason studies how reason is built, how it changes, how it might be rebuilt. Reason is not a given—it's an achievement, always in progress, always at risk.
Theory of Constructed Reason "You think reason is just thinking clearly. Theory of Constructed Reason says: reason is a practice you learned—in school, from parents, through argument. It was constructed, and it's still under construction. Clear thinking in one context may be confusion in another. Reason isn't a possession; it's a process, built and rebuilt in every conversation."

Theory of Constructed Rationality
The claim that rationality is not a universal faculty but a constructed standard—built differently in different contexts, serving different purposes, reflecting different values. What counts as rational in science differs from what counts as rational in law, in ethics, in everyday life. What counted as rational in one era may seem irrational in another. Theory of Constructed Rationality doesn't abandon reason—it recognizes that reason is always reason-within-a-tradition, reason-for-a-purpose, reason-shaped-by-history. Rationality is constructed, and understanding its construction is part of using it well.
Theory of Constructed Rationality "You appeal to rationality as if it's neutral, universal. Theory of Constructed Rationality says: whose rationality? When? For what purpose? The rationality of a corporate boardroom differs from the rationality of an indigenous community. Both are rational; both are constructed. The question isn't 'is it rational?' but 'what kind of rationality, serving what ends, constructed by whom?'"
