the theory of defeasible reasoning

Defeasible reasoning is a type of logical thinking that allows for conclusions to be re-evaluated or reversed when new information emerges. Unlike traditional logic, where conclusions are absolute, defeasible reasoning recognizes that our knowledge can be incomplete or uncertain. For example, we might conclude that "birds can fly," but learn that "ostriches are birds that cannot fly." This flexibility is important in everyday decision-making and reasoning, enabling us to adapt our beliefs based on new evidence or insights, which is essential in navigating the complexities of general knowledge.
