The book’s longest chapter, “Down with Childhood,” chronicled the ways that children’s lives had become constrained and regulated in modern society. “With the increase and exaggeration of children’s dependence, woman’s bondage to motherhood was also extended to its limits,” Firestone wrote. “Women and children were now in the same lousy boat.” The argument drew the appreciation of one notable feminist, which must have pleased Firestone. Simone de Beauvoir told Ms. that only Firestone “has suggested something new,” noting how the book “associates Women’s Liberation with children’s liberation.”
