Query: Thought provoking and fun to read.

It's humorous and it also shows how hard it is to expand your outlook. The difficulty for someone living in one dimension (point land) trying to conceive of two dimensional life (flatland) and the flatlanders trying to imagine three dimensional life (space land).It was written over one hundred years ago and I have read reviews that say it's politically incorrect, but I don't see it. Anyway, it's worth looking at and the price is right.
