Ruddick is best known for her analysis of the practices of thinking that emerge from the care of children. She argued that mothering is a conscious activity that calls for choices, daily decisions and a continuing, alert reflectiveness. Lisa Baraitser describes her contribution: "Along with Adrienne Rich, Ruddick was probably the most important philosophical thinker to address the issue of mothering and motherhood since second-wave feminism, and in a similar spirit to that of Grace Paley, to extend her analysis of mothering under patriarchy to the development of the valuesnecessary to oppose militarism and war."
