The women capture them, meet them with calm, un-fearful competence rather than awe, and educate them. Each man's ideas about women fail against the reality: Terry's conquest fantasy ends in his expulsion after he attempts to force himself on his wife Alima, Jeff's pedestal worship proves irrelevant, and only Van's willingness to be corrected works.
The traits labelled 'feminine' — timidity, vanity, coquetry, physical frailty — are not inherent to women but are adaptations to economic dependence on men and to competing for them. Remove men as the source of livelihood and status, and those traits disappear, leaving only 'human' qualities; the men cannot recognise the women as women because what they called womanliness was a product of their own presence.
Herland treats raising children as the highest collective function rather than a private domestic duty: children belong to the whole community and are raised by trained specialists instead of solely by the biological mother. Every institution — education, economy, population policy — is designed around producing better next generations, and the women voluntarily limit births to what their land can sustain.
Herland children learn through environments deliberately engineered so that exploration, games and following their own curiosity lead to real knowledge, without punishment, grading, or fear. The book argues that obedience-based schooling produces rebellion and ignorance, whereas when adults design the setting rather than enforce the lesson, children willingly learn more.
