Flatland、Section 21の要約

起こる出来事

1. The narrator wakes eager to spread knowledge of three dimensions, beginning with his Wife.
2. A herald announces punishments for claims about another world, so the narrator chooses mathematical demonstration instead of personal revelation.
3. He avoids teaching his Sons, misleads his Wife about the mysterious visitor, and summons his Grandson as his first pupil.
4. Behind a locked door, he reviews how points and lines generate figures and asks about a square moving beyond two dimensions.
5. The repeated proclamation frightens the Grandson, who denies seriously suggesting a third dimension.
6. The narrator fails to demonstrate the movement with a square, and his laughing Grandson leaves.
