Theories of the body are particularly important for feminists because historically (in the humanities) the body has been associated with the feminine, the female, or woman, and denigrated as weak, immoral, unclean, or decaying.

Kristeva emphasizes the maternal function and its importance in the development of subjectivity and access to culture and language. While Freud and Lacan maintain that the child enters the social by virtue of the paternal function, specifically paternal threats of castration, Kristeva asks why, if our only motivation for entering the social is fear, more of us aren't psychotic?

Kristeva argues that there are three phases of feminism. She rejects the first phase because it seeks universal equality and overlooks sexual differences. She implicitly criticizes Simone de Beauvoir and the rejection of motherhood; rather than reject motherhood Kristeva insists that we need a new discourse of maternity.
