Counterfactual Logic

Counterfactual logic is a branch of modal logic that explores what could have happened if things were different. It evaluates "what if" scenarios, examining alternate realities based on changes in facts or events. For instance, it might ask, "What if I had taken a different route home?" In doing so, it helps us understand causality and the relationships between events. This logic is important in fields like philosophy, decision theory, and artificial intelligence, as it allows us to reason about possibilities and their implications, enabling better decision-making by considering outcomes that did not actually occur.
