America grows older yet stays focused on its young. Whatever hill we try to climb, we're "over" it by fifty and should that hill involve entertainment or athletics we're finished long before. But if younger is better, it doesn't appear that youngest is best: we want our teachers, doctors, generals, and presidents to have reached a certain age. In context after context and contest after contest, we're more than a little conflicted about elders of the tribe; when is it right to honor them, and when to say "step aside"? In Lastingness , Nicholas Delbanco, one of America's most celebrated men of letters, profiles great geniuses in the fields of visual art, literature, and music-Monet, Verdi, O'Keeffe, Yeats, among others - searching for the answers to why some artists' work diminishes with age, while others' reaches its peak. Both an intellectual inquiry into the essence of aging and creativity and a personal journey of discovery, this is a brilliant exploration of what determines what one needs to do to keep the habits of creation and achievement alive.
