Flatland is divided into two parts: front and back. In the first part, the world of Flatland is described by a square; while the second part talks about the zero-dimensional and one-dimensional worlds, the three-dimensional space country that is difficult for Flatlanders to understand, and briefly mentions the analogy and imagination of four-dimensional space. Abbott uses the "square", a fictional two-dimensional space in the book, to express his bitter satire on the class system of the Victorian era, and the longer-term contribution of this novel is the examination of dimensions. In 1884, the second industrial revolution had not yet been completed, and modern physics had not yet even a shadow. Abbott was already imagining high-dimensional space in "Flatland". Even now that people have proposed that the microscopic world may be composed of ten or higher dimensions, "Flatland" is still highly praised and cited as an "enlightenment book" on multi-dimensional space.
