This section serves as the publisher's preface to the second revised edition of Flatland, detailing the hardships faced by the author. Years of imprisonment, skepticism, and old age have diminished the Square's intellectual vigor, leading the editor to address two primary criticisms on his behalf.
The first objection concerns intellectual logic, noting that inhabitants of Flatland should perceive length and thickness rather than length alone. Through the editor, the Square explains that while a third dimension exists as brightness or an imperceptible height, it cannot be measured or directed without proper sensory comprehension. He compares this plight to an inhabitant of Spaceland facing a Fourth Dimension visitor, highlighting the universal tendency of societies to persecute those who challenge dimensional prejudices.
The second objection addresses moral criticisms, specifically accusations of misogyny and aristocratic bias within the text. Although the Square's views on women and lower classes have evolved during his confinement, he maintains his role as an impartial historian reflecting his society. The preface concludes with the author's hope that his work will inspire imagination and humility among readers in Spaceland when considering realms beyond ordinary experience.
