"Flatlands" is a novella written by Edwin A. Abbott in 1884. It presents a two-dimensional world inhabited by geometric shapes, where social hierarchy is determined by the number of sides a shape has. The story is narrated by a square who describes life in this flat world, highlighting the limitations of its inhabitants' understanding of dimensions. The novella serves as an allegory for Victorian society, critiquing class distinctions and the resistance to new ideas. As the square encounters a three-dimensional being, he begins to grasp the concept of higher dimensions, challenging the rigid beliefs of his flat world and encouraging readers to think beyond their own limitations.
