"Asking about twins, Alessandra Piontelli has made astonishing discoveries about human nature and culture. This brilliant book reads as an adventure story, taking us along on a remarkable doctor's travels into worlds so remote and yet so human that they illuminate many of our own quandaries about mothers and children." -Carol Gilligan, author of In a Different Voice ...

Is it that having twins overburdens our capacity to look after the young, or are there other reasons as well? Dr. Piontelli explores this odd dilemma with great learning and admirable imagination." -Jerome Bruner, author of The Process of Education "Twins in the World reads like a good novel, as well as good scientific observation. Piontelli shows us something wondrous, like the face of the moon up close. She then leads us around to the hidden side where we glimpse human nature and ourselves differently than ever before." - Daniel Stern, author of The Interpersonal World of the Infant Show Less
