It was a full novel my stepmom owned.
The paperback cover was a wizard with robes and a hat. It gave me the vibes of being a fantasy comedy. Kinda like the Another Fine Myth series.
The first paragraph was “Some people say the entire universe is carried around in a marble bag, and if that were true then that would mean the man and his marble bag are also apart of the universe so they’d be inside of it too. But then again they’re just as likely to be right as anyone else.” Or something along those lines. It definitely mentioned the marble bag theory, and addr3ssed the paradox. The concept of that always stuck with me but I never had a chance to read the whole book.
If this rings a bell with anyone I’d be greatful for any help
