  • Russel's paradox is trivial to solve. It's just defined in a sneaky way. It falsely presents the problem as stateless. Once you consider system state, you understand why nature / reality has no problem with this false paradox. In the barber's case, the sneaky part is that "shaves himself" is specified too vaguely, to throw you off. The key is that the act of shaving someone (whether it's yourself or someone else) changes the state of the system and thus the classification of which men shave themselves. Let's include system state and a more precise / honest specification of the problem: Each morning, the barber shaves all men who did not shave themselves the the day before. As you can see, the problem resolved itself by properly considering system state and removing the ambiguity in what "shaves himself" means. The barber will, or course, shave other men every day and himself every other day.
