A 20th-century revival and refinement of Classical Logic that attempts to address its limitations while preserving its core insights. Neo-Classical approaches keep the basic framework but introduce more sophisticated tools: modal logic (necessity and possibility), multi-valued logic (more than two truth values), and higher-order quantification. It's Classical Logic with an upgrade package—same operating system, better apps. Neo-Classicists believe the old tools are basically right but need to handle complexity the ancients never imagined, like time travel paradoxes or the logical structure of infinite sets.
"You can't solve a time travel paradox with Classical Logic—it just throws an error. Neo-Classical Logic at least gives you a debug console and a few more truth values to work with before your brain crashes."
