Da Costa's Logic

Da Costa's logic is a formal system developed to analyze reasoning involving contradictions. Unlike classical logic, which deems any statement from a contradiction to be true, Da Costa’s approach allows for contradictions (called "paradoxes") without collapsing the entire system. It introduces special rules to control how contradictions are handled, preserving meaningful reasoning and inference. This logic is useful in areas like philosophy and computer science, where inconsistent information may occur but doesn’t necessarily invalidate the whole theory or system. Essentially, it provides a structured way to reason even when some contradictions are present.
