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."*

Theory of Logical Constructions

The theory that logic is not discovered but constructed—built by communities, shaped by cultures, developed through history, contingent rather than necessary. Logical Constructions argues that what counts as logical varies across time and place, that different societies develop different reasoning norms, that even the laws of logic are human products. This doesn't mean logic is arbitrary; it means logic is a tool, not a revelation—a human creation for human purposes. The Theory of Logical Constructions explains why different cultures reason differently, why logical systems change over time, why what seems self-evident in one context seems strange in another. Logic is constructed, not found—and constructed things can be reconstructed.

Theory of Logical Constructions Example: "He'd always thought logic was universal—the same for everyone, everywhere, always. Then he encountered the Theory of Logical Constructions and learned that different cultures had developed different logics, that even the law of non-contradiction wasn't universal, that logic was a human product like any other. His certainty wavered; his curiosity grew. Logic wasn't less real; it was differently real—made, not found."
