women as having a "genius that belongs" to them and called on them to use it to restore "sensitivity for human beings in every circumstance. Women are mothers and caregivers as well as participants in every realm of human endeavor. He describes the 'feminine genius' as including empathy, interpersonal relations, emotive capacity, subjectivity, communication, intuition and personalization. In the controversial section 24 of this letter, John Paul II defends the equality of women and argues that husbands and wives are to be mutually submissive to each other. John Paul II had begun his theologically-based affirmation of integral gender complementarity in his Wednesday audiences between 1979 and 1984, in what is now compiled as the Theology of the Body. In this work, he describes his belief that men and women are formed as complementary human beings for the sake of loving and being loved. John Paul II continued his call for women to become advocates of humanity in his Apostolic Letter to Women prior to the 1995 Beijing Women's conference. Since then, women interested in advocating for the person--along with their male collaborators--have been developing personalist feminism.

Women have also been developing new feminism as a philosophical theory about sexual complementarity. They agree that being the equal to men in their professional and social capacities does not require denying their physical differences as women nor the importance of being a mother whether physically or spiritually.

The first western philosopher to articulate a complete theory of sex complementarity was Hildegard of Bingen, a 12th-century Benedictine nun. Her advances were soon buried by the 13th century Aristotelian Revolution, and the lack of higher education for women in the following centuries. Philosophical developments in the concept of integral gender complementarity were popularized in the early 20th century by two students of Edmund Husserl: Dietrich von Hildebrand and Edith Stein. Von Hildebrand argued against the "terrible anti-personalism" of his age, stating that it is the "general dissimilarity in the nature of both which enables... a real complementary relationship". Stein revived the metaphysics of Thomas Aquinas to
