Paraconsistent Logic

A branch of logic that allows contradictions to exist without exploding the entire system—unlike classical logic, where a single contradiction allows you to prove anything (the principle of explosion). Paraconsistent logic acknowledges that real-world information is often contradictory: eyewitnesses disagree, scientific studies conflict, and your phone's terms of service both grant and restrict rights simultaneously. Instead of treating contradiction as catastrophic, paraconsistent logic develops frameworks that can tolerate inconsistency, extract useful information, and reason productively even when premises don't perfectly align. It's the logic of living with cognitive dissonance, managing competing priorities, and still managing to function despite the fundamental contradictions of existence.

*Example: "She used paraconsistent logic to navigate her job. The company claimed to value work-life balance while expecting 60-hour weeks. Classical logic would say these can't both be true, leading to resignation or breakdown. Paraconsistent logic allowed her to hold both, notice the contradiction, and still show up Monday. The system was broken; she worked anyway. The contradiction didn't destroy her; she just lived with it."*
