Nonmonotonic Logic
Nonmonotonic logic is a type of reasoning that allows conclusions to be withdrawn when new information contradicts them. Unlike traditional logic, where adding new facts never changes previously established truths, nonmonotonic logic reflects how humans think and adapt their beliefs based on new evidence. For example, if you believe birds can fly, you might revise that belief upon learning about ostriches. In the context of general knowledge, it helps in understanding and modeling uncertain or changing information, making it useful in artificial intelligence and decision-making processes.

Nonmonotonic logic is a type of reasoning that allows for flexibility in drawing conclusions based on general knowledge. Unlike traditional logic, where conclusions are fixed once established, nonmonotonic reasoning acknowledges that new information can change prior conclusions. For instance, if we know that birds typically fly, we might conclude that a sparrow flies. However, if we learn that the sparrow is injured, we might revise our conclusion. This approach better reflects real-world reasoning, where our beliefs adapt as we acquire new facts. It recognizes that knowledge is often incomplete and subject to change.
