When mediums cultivate relationships between the living and the dead, argues Diana Espírito Santo, they develop, learn, sense, dream, and connect to multiple spirits (muertos), expanding the borders of the self. This understanding of selfhood is radically different from Enlightenment ideas of an autonomous, bounded self and holds fascinating implications for prophecy, healing, and self-consciousness. Developing the Dead shows how Espiritismo's self-making process permeates all aspects of life, not only for its own practitioners but also for those of other Afro-Cuban religions.
