Cavarero refutes a long-standing set of assumptions in moral philosophy by contesting the classical figure of the homo erectus or 'upright man,' and by proposing a feminist, altruistic, open model of the subject-one inclined toward others.

In this new and accessible book, Italy's best known feminist philosopher examines the moral and political significance of vertical posture in order to rethink subjectivity in terms of inclination. Contesting the classical figure of homo erectus or "upright man," Adriana Cavarero proposes an altruistic, open model of the subject—one who is inclined toward others. Contrasting the masculine upright with the feminine inclined, she references philosophical texts (by Plato, Thomas Hobbes, Immanuel Kant, Hannah Arendt, Elias Canetti, and others) as well as works of art (Barnett Newman, Leonardo da Vinci, Artemisia Gentileschi, and Alexander Rodchenko) and literature (Marcel Proust and Virginia Woolf).
