How can we achieve and sustain a "decent" liberal society, one that aspires to justice and equal opportunity for all and inspires individuals to sacrifice for the common good? In this book, a continuation of her explorations of emotions and the nature of social justice, Martha Nussbaum makes the case for love. Amid the fears, resentments, and competitive concerns that are endemic even to good societies, public emotions rooted in love--in intense attachments to things outside our control--can foster commitment to shared goals and keep at bay the forces of disgust and envy.
