A logical framework that is closed to external influence—its axioms are fixed, its rules are unchanging, and no new information or perspective can alter its operations. Closed logical systems are characteristic of mathematics (within a given axiomatic system), of formal logic (within a given calculus), and of rigid ideologies (within a given framework). They're clean, consistent, and predictable—and completely unable to learn or adapt. Closed systems are useful for certain purposes (formal proofs, computer programs) but disastrous for understanding a changing world. When applied to life, they produce certainty without wisdom, stability without growth.
Example: "Her mind was a closed logical system—axioms fixed decades ago, rules unchanging, no new information allowed. Arguments bounced off, evidence dissolved, experience meant nothing. The system was consistent, perfectly consistent, and perfectly useless for navigating a changing world. She was never wrong and never learned."
