"Flatland: A Romance of Many Dimensions" is a novella written by Edwin A. Abbott in 1884. It is set in a two-dimensional world inhabited by geometric shapes, where social hierarchy is determined by the number of sides a shape has. The story follows a square named A. Square, who narrates his experiences and observations about life in Flatland. The narrative explores themes of perception, dimensions, and the limitations of understanding. A. Square's encounter with a three-dimensional being, a sphere, challenges his views and introduces him to the concept of higher dimensions, ultimately questioning the nature of reality and existence.
