Flatland, Section 12 summary
Section 12 of 22 · Part 1: This World · 7 min to read the section
In Section 12, the Square explains the Circles’ claim that bodily shape determines conduct, then exposes difficulties in punishment, family life, and marriage. He also argues that denying women education forces males to maintain conflicting languages and beliefs, and he appeals to the authorities to reconsider that policy.
What happens
- The Circles teach that bodily shape determines conduct, so irregular figures need treatment rather than moral judgment.
- The Square finds this doctrine difficult to apply when his grandson uses it to excuse disobedience and demand sweets.
- The Circles require fathers to put descendants first, while marriage depends on state-certified female ancestry.
- The Square warns that Circles neglect their wives’ ancestry, risking infertility, irregular offspring, and constitutional collapse.
- He explains that withholding education from women forces males to use separate domestic and scientific vocabularies.
- He appeals for reconsideration of female education because this divided training appears to weaken male understanding.
