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.
