Could an all-powerful being create a stone even they couldn't lift?
If the being can create such a stone, then there's something they can't do (lift it); if they can't create it, there's also something they can't do (create it). Either way, their power seems to have a limit, which seems to contradict the very definition of omnipotence. Medieval scholastic philosophers used this puzzle to probe whether "unlimited power" is even coherent, with some concluding that true omnipotence only requires the ability to do anything logically possible.
