[Flatland] Could you convince the 0th dimension being to believe in higher dimensions?

He believes that everything is himself, including thoughts and ideas. Would he adopt spoken ideas about higher dimensions as his own so much that he believes them?

I feel like in order to understand the dimensions above you, you'd need to experience the dimensions below.  Without those experiences, it's far more difficult to make the leap to understanding something greater.

A Square got to experience Lineland, so when he was introduced to Spaceland, he was able to understand the experience.

The Sphere (and the reader) gets to experience Flatland, so you'd think that if we were pulled into Hyperspaceland, we'd be able to understand what's going on - if we're willing.

But in Pointland, there's no step below, so Pointy couldn't learn to recognize the ignorance of believing there's nothing greater than what you can see.  Because of that, and because he's all that he's ever known (compared to the other dimensions, which are densely populated by segments, shapes, and beings), it'd be pretty hard for him to learn what a "line" is.
