Flatland

In 1884, Edwin Abbott Abbott published a mathematical adventure set in a two-dimensional plane world, populated by a hierarchical society of regular geometrical figures--who think and speak and have all-too-human emotions. Since then Flatland has fascinated generations of readers, becoming a perennial science-fiction favorite. By imagining the contact of beings from different dimensions, the author fully exploited the power of the analogy between the limitations of humans and those of his two-dimensional characters.
