A broad term for logical systems that fundamentally break with the Classical tradition, often inspired by developments in quantum mechanics, continental philosophy, or computer science. Post-Classical Logic questions the very foundations: maybe the excluded middle isn't always excluded; maybe contradictions can be productive; maybe truth isn't the only thing logic should track. These systems embrace paradox, explore paraconsistency (allowing contradictions without exploding), and treat logic less as a mirror of reality and more as a tool among tools. It's logic that has accepted its own contingency.
"Quantum mechanics requires a Post-Classical Logic where particles can be in two states at once. Your relationship status might also require Post-Classical Logic if you're in that 'it's complicated' phase where classical true/false just doesn't capture the situation."
