Logic Forging

The deliberate fabrication of a false chain of deductive reasoning, presenting a series of statements that appear to follow formal logical rules but which contain a secretly invented or twisted rule. This creates a simulacrum of a logical proof that "proves" something false. It's like writing a mathematical proof where you quietly redefine what the equals sign means halfway through.

Example: "He forged a logic to prove his conspiracy: 'Premise 1: Powerful people keep secrets. Premise 2: I have a secret. Conclusion: I am powerful. If I am powerful and they are powerful, we are part of the same secret network. QED.' He'd forged a link between trivial and grand secrets, creating a fake logical bridge to inflate his own importance." Logic Forging

Logic Crafting

The careful, architectural design of a reasoning system using valid logical rules, but with carefully chosen, biased, or false premises that the audience is likely to accept. The logic itself is sound, but the entire structure is engineered to lead to a pre-determined outcome because the starting points were rigged. It's giving someone a perfectly accurate map that leads directly to your own boutique because you secretly defined "destination" as "my store."

Example: "The lawyer crafted his logic flawlessly: 'If the defendant was at home, he couldn't be at the crime scene. His smart home data shows his lights were on at home. Therefore, he was at home.' The logic was valid, but he'd crafted it to omit the fact the defendant's lights were on a timer—a premise he carefully avoided examining." Logic Crafting

Theory of Constructed Logic

The provocative idea that even the rules of logic (like non-contradiction: a thing cannot be both A and not-A) are not timeless, Platonic truths discovered by the brain, but are cognitive tools our minds and cultures have constructed because they are useful for survival and communication. Other systems of reasoning (dialetheism, fuzzy logic) can be constructed, showing that our "common sense" logic is one possible system among many.

*Example: "In our logic, 'the statement is true or false' seems obvious. In quantum computing, a qubit can be in a superposition—both 1 and 0 at once. The Theory of Constructed Logic suggests our everyday logic isn't the law of the universe, but a very useful mental model we built to navigate a middle-sized, slow-moving world. For the subatomic realm, we had to construct a weirder logic."*

Logical Pragmatism

A philosophical approach that judges the validity of ideas, arguments, and beliefs primarily by their practical consequences and usefulness in navigating the world, rather than by their abstract, formal logical purity or their correspondence to an absolute "truth." If a belief leads to successful prediction, effective action, or psychological well-being, it holds pragmatic value, even if it contains logical imperfections or is unprovable in a closed system.

Example: Believing in free will, despite philosophical debates about determinism, is Logical Pragmatism. The belief has immense practical consequences—it underpins our systems of law, morality, and personal motivation. Even if it's logically fuzzy, it's useful and thus, for a pragmatist, holds a form of validity that a perfectly logical but paralyzing belief in absolute determinism does not.

Closed System Logic

Reasoning that operates within a strictly defined, self-contained set of axioms, rules, or assumptions, deliberately ignoring or rejecting any external information or context that might challenge the internal consistency of the system. It values internal coherence over correspondence with a messy reality. This is the logic of pure mathematics, certain ideological dogma, and airtight (but possibly irrelevant) theoretical models.

Example: A libertarian think-tank model that "proves" minimal government always leads to optimal outcomes, but which excludes variables like historical racism, environmental externalities, or public health crises from its equations, is using Closed System Logic. The argument is perfectly logical inside its own defined world, but may fail catastrophically when applied to the open system of real human society.

Open System Logic

A mode of reasoning that acknowledges and incorporates external factors, new information, feedback loops, and changing contexts. It treats arguments and systems as permeable and evolving, where conclusions are tentative and must be updated when new data or perspectives from "outside" the initial frame are introduced. It is the logic of science, adaptive engineering, and pragmatic philosophy—flexible and responsive to reality.

Example: Designing a traffic flow system using Open System Logic means you install sensors, monitor accident data, and are ready to change light timings or road layouts based on real-world usage, weather, and new housing developments. The system isn't a fixed, perfect solution; it's a responsive organism that evolves with its environment.

Logical Bias

The error of privileging formal, deductive logic above all other ways of knowing (empathy, intuition, experiential knowledge, moral reasoning) and dismissing any argument that doesn't fit into a neat syllogism as "illogical" and therefore invalid. It's a bias that mistakes a specific tool for the entire toolbox of human understanding, often to coldly justify inhuman conclusions.

Example: "Logically, a corporation's only duty is to maximize shareholder value. Therefore, laying off 10,000 people to boost stock price is not just permissible, it's illogical not to do it." This Logical Bias uses a narrow, amoral logical framework to justify a human catastrophe, dismissing ethical concerns as sentimental "illogic."
