Flatland

Imagine living in a super flat world like a drawing on paper, where everybody is a shape: tiny triangles are poor workers, squares like the storyteller are middle class, and circles are bosses. One night, a square guy dreams of a boring world of just straight lines, then a magic ball from a 3D world lifts him up to show him there's an 'up' direction with amazing big spaces. He tries telling his flat friends about it, but they think he's crazy, lock him in jail, and only his grandson believes him later. It's a cool story about how hard it is to imagine things beyond what you can see!

Flatland: A Romance of Many Dimensions by Edwin Abbott Abbott presents a two-dimensional universe where inhabitants are geometric polygons, with social hierarchy strictly determined by the number of sides: isosceles triangles at the bottom as laborers, equilaterals as professionals, higher polygons as nobility, and circles as the priestly elite. Women, reduced to mere straight lines, are feared for their lethal pointed ends and granted special legal protections due to their volatility. Narrated by A Square, a modest equilateral professional, the story exposes the absurdities of this rigid, sightless society reliant on touch and sound for recognition, satirizing Victorian England's class prejudices, gender roles, and clerical authority through exaggerated geometric conventions. A Square first dreams of Lineland, a one-dimensional realm of monotonous lines ruled by a tyrannical monarch, illustrating perceptual myopia. Then, a benevolent Sphere from three-dimensional Spaceland elevates him to witness volume and height, shattering his worldview. Zealously returning to proselytize the third dimension, A Square faces scorn, mob violence, and imprisonment for heresy. His grandson eventually carries the torch of enlightenment, but the tale ends in poignant resignation, profoundly exploring how limited senses confine understanding and how societies resist paradigm-shifting truths.
