The Flat: A Multidimensional Novel by Edwin Abbott is a philosophical allegory that explores the gradual discovery and understanding of new realities different from those known in the ordinary three-dimensional world. In this book, the reader will immerse himself in the world of Lines, Planes, Cubes and other geometric figures, which are endowed with their own imaginary worlds and possibilities. The author leads the reader through an exciting journey of learning about new dimensions, leaving behind him vast expanses of important philosophical and anthropological questions about the perception of reality. "Flat" is not only a work of science fiction, but also a challenge to think about the limitations of our perception of the world and the possibilities of its expansion.
