Read this passage.
“And that's not all,” the number devil added, picking up a walking stick with a silver knob and twirling it in front of Robert's nose. “When you get to five million etcetera, you can go on. Indefinitely. There's an infinite number of numbers.”

Robert didn't quite know whether to believe him.

“How can you be so sure?" he asked. "Have you ever tried?”

“Can't say I have,” the devil answered. “It would take too long, for one thing. And it makes no sense anyway. It would be a waste of time."

Robert didn't see why.

“Either I can count to the end, in which case there is no such thing as infinity, or there is no end and I can't count to it.”

“Wrong!” the number devil shouted, his mustache quivering, his eyes bulging, and his face turning red with rage.
