Flatland, Section 5 summary
Section 5 of 22 · Part 1: This World · 7 min to read the section
In Section 5, the narrator explains how Flatlanders identify people through hearing and touch, despite seeing almost everyone as a line. He describes dangerous introductions, an ancestral accident, and schools that exploit low-angle Isosceles people, showing how recognition practices support social rank while leaving a third method unexplained.
What happens
- The narrator explains that voices distinguish friends and some classes, but imitation and similar voices make hearing unreliable.
- Touch identifies most classes through a single angle, although polygons with many sides are harder to distinguish.
- Feeling requires stillness because a sudden movement can injure or kill the person making contact.
- The narrator recounts an ancestor’s accidental stabbing of a Polygon and the resulting setback to his family’s advancement.
- Schools teach angle recognition with chained Isosceles people, sometimes withholding food and replacing them monthly.
- The narrator judges touch more reliable than hearing but notes that its dangers encourage another method.
