How many people live in Pointland?

I don't think that a population is directly given to the reader. Chapter 20 is short, yet profound in meaning. When Square returns to Flatland, he is frightened to tell his wife his experience, not because of fear she will tell others, but in the knowledge she will not understand. During his dream, he visits Pointland, the abyss dimension, the land of no dimension. In it, he sees a small creature, convinced he is the only object in the universe. Sphere's point that self-complacence is a sign of ignorance, and evil, is symbolic of Abbott's own Victorian era, in a number of ways. First, the concept of God appears in this no dimensional land, as the being believes itself to be the center of everything. By noting the ignorance of such a belief, Abbott is declaring not that God is ignorant, but that any society refusing to aspire to further notions, or entertain other conceptual ideas of God, is ignorant. In addition, Abbott seems to be noting the upper classes, or those who see themselves as higher than others and complacent in their own worlds, are ignorant if they refuse to aspire to higher learning.
