From eminent critic Peter Brooks, an exploration of the modern preoccupation with identity "We know that it matters crucially to be able to say who we are, why we are here, and where we are going," Peter Brooks writes in Enigmas of Identity. Many of us are also uncomfortably aware that we cannot provide a convincing account of our identity to others or even ourselves. Despite or because of that failure, we keep searching for identity, making it up, trying to authenticate it, and inventing excuses for our unpersuasive stories about it. This wide-ranging book draws on literature, law, and psychoanalysis to examine important aspects of the emergence of identity as a peculiarly modern preoccupation. In particular, the book addresses the social, legal, and personal anxieties provoked by the rise of individualism and selfhood in modern culture. Paying special attention to Rousseau, Freud, and Proust, Brooks also looks at the intersection of individual life stories with the law, and considers the creation of an introspective project that culminates in psychoanalysis. Elegant and provocative, Enigmas of Identity offers new insights into the questions and clues about who we think we are.

How identity influences the economic choices we make Identity Economics provides an important and compelling new way to understand human behavior, revealing how our identities—and not just economic incentives—influence our decisions. In 1995, economist Rachel Kranton wrote future Nobel Prize-winner George Akerlof a letter insisting that his most recent paper was wrong. Identity, she argued, was the missing element that would help to explain why people—facing the same economic circumstances—would make different choices. This was the beginning of a fourteen-year collaboration—and of Identity Economics. The authors explain how our conception of who we are and who we want to be may shape our economic lives more than any other factor, affecting how hard we work, and how we learn, spend, and save. Identity economics is a new way to understand people's decisions—at work, at school, and at home. With it, we can better appreciate why incentives like stock options work or don't; why some schools succeed and others don't; why some cities and towns don't invest in their futures—and much, much more. Identity Economics bridges a critical gap in the social sciences. It brings identity and norms to economics. People's notions of what is proper, and what is forbidden, and for whom, are fundamental to how hard they work, and how they learn, spend, and save. Thus people's identity—their conception of who they are, and of who they choose to be—may be the most important factor affecting their economic lives. And the limits placed by society on people's identity can also be crucial determinants of their economic well-being.

A wide-ranging and original study on how enigmas and riddles work in literature.

"What do we fear most? Repetition or difference? The return of a barbarism that is remote and prehistoric or the advent of a barbarism that is technological as post-human?"

Identity: The Necessity of a Modern Idea is the first comprehensive history of identity as the answer to the question, "who, or what, am I?" It covers the century from the end of World War I, when identity in this sense first became an issue for writers and philosophers, to 2010, when European political leaders declared multiculturalism a failure just as Canada, which pioneered it, was hailing its success. Along the way the book examines Erik Erikson's concepts of psychological identity and identity crisis, which made the word famous; the turn to collective identity and the rise of identity politics in Europe and America; varieties and theories of group identity; debates over accommodating collective identities within liberal democracy; the relationship between individual and group identity; the postmodern critique of identity as a concept; and the ways it nonetheless transformed the social sciences and altered our ideas of ethics. At the same time the book is an argument for the validity and indispensability of identity, properly understood. Identity was not a concept before the twentieth century because it was taken for granted. The slaughter of World War I undermined the honored identities of prewar Europe and, as a result, the idea of identity as something objective and stable was thrown into question at the same time that people began to sense that it was psychologically and socially necessary. We can't be at home in our bodies, act effectively in the world, or interact comfortably with others without a stable sense of who we are. Gerald Izenberg argues that, while it is a mistake to believe that our identities are givens that we passively discover about ourselves, decreed by God, destiny, or nature, our most important identities have an objective foundation in our existential situation as bodies, social beings, and creatures who aspire to meaning and transcendence, as well as in the legitimacy of our historical particularity.
