Margaret Atwood in The Atlantic:
In the early years of the 1980s, I was fooling around with a novel that explored a future in which the United States had become disunited. Part of it had turned into a theocratic dictatorship based on 17th-century New England Puritan religious tenets and jurisprudence. I set this novel in and around Harvard University—an institution that in the 1980s was renowned for its liberalism, but that had begun three centuries earlier chiefly as a training college for Puritan clergy.
In the fictional theocracy of Gilead, women had very few rights, as in 17th-century New England. The Bible was cherry-picked, with the cherries being interpreted literally. Based on the reproductive arrangements in Genesis—specifically, those of the family of Jacob—the wives of high-ranking patriarchs could have female slaves, or “handmaids,” and those wives could tell their husbands to have children by the handmaids and then claim the children as theirs.
Although I eventually completed this novel and called it The Handmaid’s Tale, I stopped writing it several times, because I considered it too far-fetched. Silly me. Theocratic dictatorships do not lie only in the distant past: There are a number of them on the planet today. What is to prevent the United States from becoming one of them?
