Non-monotonic Logic
Non-monotonic logic is a type of reasoning where adding new information can change previous conclusions. In traditional logic, if something is true, it always remains true when new facts are introduced. However, in non-monotonic logic, especially in contexts like modal logic (which deals with possibilities and necessities), new evidence can lead us to revise our beliefs. This flexibility reflects real-world reasoning, where our understanding evolves as we learn more, allowing for conclusions that are more applicable to complex and changing situations.

Non-monotonic logic is a type of reasoning that allows conclusions to be retracted when new information becomes available. Unlike traditional logic, where once something is proven true it remains true, non-monotonic logic acknowledges that our understanding can change as we learn more. For example, if we know most birds can fly and then discover that penguins are birds that cannot fly, we adjust our conclusions. This approach is valuable in general knowledge because it reflects how we often update our beliefs in real life, accommodating new evidence and making our reasoning more flexible and realistic.
