Faces are what newborns naturally seek. They are the objects of our love, trust, fear, longing, and memory. They inspire poetry and the visual arts. We rely on faces to reveal mood and character, allowing them to influence hiring decisions, criminal convictions, and elections. In this magisterial work, Todorov takes us on a tour of the face, its role in human affairs, and its power to influence and mislead. You'll always look at faces, but never the same way again. - Eldar Shafir, coauthor of Scarcity: The New Science of Having Less and How It Defines Our Lives
