"Quine's Theorem"

Quine's Theorem states that in propositional logic, it's impossible to create a perfect, complete, and sound system for all logical truths using only a finite set of axioms and inference rules. In simpler terms, no matter how carefully you choose your initial truths and reasoning steps, there will always be some logical statements that the system can't prove or disprove. This highlights inherent limitations in formal logical systems, suggesting that some truths are unprovable within any given finite logical framework.
