Mary Catherine Bateson, sociologist, daughter of Margaret Mead, and author of the groundbreaking books Peripheral Visions and Composing A Life, sees aging today as an “improvisational art form calling for imagination and the willingness to learn.” Her new book is an ardent, affirming study of the experiences of men and women—herself included—who, upon entering the period she refers to as "Adulthood II," have found new meaning and new ways to contribute to society, composing their lives in new patterns. She challenges us to approach our later lives with the full force of our imagination, curiosity, and enthusiasm. She also speaks to us as members of a larger society concerned about the world that our children and grandchildren, born and not yet born, will inherit.
