Focusing on the art of self-portraiture, this effortlessly engaging exploration of the lives of artists sheds fascinating light on some of the most extraordinary portraits in art history. Self-portraits catch your eye. They seem to do it deliberately. Walk into any art gallery and they draw attention to themselves. Come across them in the world’s museums and you get a strange shock of recognition, rather like glimpsing your own reflection. For in picturing themselves artists reveal something far deeper than their own physical looks: the truth about how they hope to be viewed by the world, and how they wish to see themselves. In this beautifully written and lavishly illustrated book, Laura Cumming, art critic of the Observer, investigates the drama of the self-portrait, from Durer, Rembrandt and Velazquez to Munch, Picasso, Warhol and the present day. She considers how and why self-portraits look as they do and what they reveal about the artist’s innermost sense of self – as well as the curious ways in which they may imitate our behaviour in real life. Drawing on art, literature, history, philosophy and biography to examine the creative process in an entirely fresh way, Cumming offers a riveting insight into the intimate truths and elaborate fictions of self-portraiture and the lives of those who practise it. A work of remarkable depth, scope and power, this is a book for anyone who has ever wondered about the strange dichotomy between the innermost self and the self we choose to present for posterity – our face to the world.

We have a strong instinct to belong to small groups defined by clear purpose and understanding--"tribes." This tribal connection has been largely lost in modern society, but regaining it may be the key to our psychological survival. Decades before the American Revolution, Benjamin Franklin lamented that English settlers were constantly fleeing over to the Indians-but Indians almost never did the same. Tribal society has been exerting an almost gravitational pull on Westerners for hundreds of years, and the reason lies deep in our evolutionary past as a communal species. The most recent example of that attraction is combat veterans who come home to find themselves missing the incredibly intimate bonds of platoon life. The loss of closeness that comes at the end of deployment may explain the high rates of post-traumatic stress disorder suffered by military veterans today. Combining history, psychology, and anthropology, TRIBE explores what we can learn from tribal societies about loyalty, belonging, and the eternal human quest for meaning. It explains the irony that-for many veterans as well as civilians-war feels better than peace, adversity can turn out to be a blessing, and disasters are sometimes remembered more fondly than weddings or tropical vacations. TRIBE explains why we are stronger when we come together, and how that can be achieved even in today's divided world.
