 The subjects' lifespans range from third-century to 20th century, as the authors' only criterion was that living women would not be included.The book contains a mixture of women with a positive and negative impact on the world, with Adams saying that feminism should reflect "the fullness of women" rather than only "women who are doing heroic, amazing things" and Sarkeesian commenting that "Women are fully human.Sometimes, that means we're terrible."
