Julia Kristeva uses both dialogue and essay to analyze our "incredible need to believe"--the inexorable push toward faith that, for Kristeva, lies at the heart of the psyche and the history of society. Examining the lives, theories, and convictions of Saint Teresa of Avila, Sigmund Freud, Donald Winnicott, Hannah Arendt, and others, this provocative intellectual maps the intersection between the desire for God and the shadowy zone in which belief resides. Kristeva suggests that human beings are formed by their need to believe, beginning with our first attempts at speech and following through to our adolescent search for identity and meaning. She then applies her insight to contemporary religious clashes and the plight of immigrant populations, especially those of Islamic origin. Even if we no longer have faith in God, Kristeva argues, we must believe in human destiny and creative possibility. Reclaiming Christianity's openness to self-questioning and the search for knowledge, the renowned thinker urges a "new kind of politics" that restores the integrity of the human community.
