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.
