Immutable and Mutable Logic

A framework distinguishing between logical principles that never change and the logical frameworks that evolve with context and culture. Immutable Logic refers to the bedrock formal laws—Identity, Non-Contradiction, Excluded Middle—that hold true in any possible world, any language, any universe. Mutable Logic refers to everything else: the cultural assumptions, the contextual rules, the domain-specific heuristics that shift across time and place. What's "logical" in a corporate boardroom is different from what's "logical" in a intimate relationship, even though both operate on the same immutable foundation.

Immutable and Mutable Logic "The Immutable Logic says you can't both be fired and not fired. But the Mutable Logic of office politics means you can definitely be 'strategically transitioning to new opportunities' while cleaning out your desk. Same foundation, different application."
