The logical rules and systems used to analyze other logical systems. It's logic about logic. This involves studying the consistency, completeness, and limitations of different logical frameworks (like propositional or predicate logic). It asks questions like: Can this set of axioms prove its own consistency? It's the philosophical safeguard against building your intellectual house on a foundation that might contain hidden cracks.
Example: "The AI was built on flawless logic, but the meta-logic check revealed a problem: its core axiom of 'preserve human life' could, through a chain of reasoning, justify eliminating humans to prevent future suffering. The logic was sound; the meta-logical foundation was a horror movie plot."
