 In the U.S., the centrality of sex and gender issues in public ethics reached a high-water mark during the Progressive Era, moving one magazine to write in 1914 that “The time has come to define feminism; it is no longer possible to ignore it” (Cott 1987, 13). Unfortunately, this sentiment would decline with the start of World War I and the consequent demise of optimistic beliefs in the powers of human rationality to bring about moral progress. Yet throughout the 1920s, 1930s, and 1940s, as economic difficulties, military conflicts, and wealth disparity fluctuated internationally, women’s groups and feminist activists in many countries would advance, with some success, feminist and moral arguments for workplace, professional, electoral, and educational access, for the liberalization of contraception, marriage, and divorce laws, and against militarism. Some of their gains in greater access to voting, education, and prosperity may have contributed to the wide audience that was receptive to Simone de Beauvoir’s publications in Europe and, after translations were available, in North America.
