“The simplest formula for the new conception of morality, which is beginning to be opposed to the moral dogma still esteemed by all society, but especially by the women, might be summed up in these words: Love is moral even without legal marriage, but marriage is immoral without love.”

Swedish writer and social thinker

Ellen Key was a Swedish writer and social thinker associated with the Modern Breakthrough movement. She lived from 1849 to 1926 and wrote on family life, ethics, education, and women's rights. She is especially remembered as an early advocate of child-centered education and parenting. Her work also placed her among the women’s suffrage advocates of her time, and her writing often returned to questions of home, moral life, and how society should shape the next generation.
