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."*
