Description: The barber paradox is a puzzle derived from Russell's paradox. It was used by Bertrand Russell himself as an illustration of the paradox, though he attributes it to an unnamed person who suggested it to him. It shows that an apparently plausible scenario is logically impossible. Specifically, it describes a barber who is defined such that he both shaves himself and does not shave himself. (Russell's popularization of his set theoretic paradox.) OR An adult male barber shaves all men who do not shave themselves, and no one else. Can he shave himself? Flaws in accepted reasoning
