The initial period of childhood is essentially about adapting to and incarnating on Earth and establishing a provisional balance between the "spiritual" and the "physical," between the prenatal cosmic and the earthly factors. During this time, according to Rudolf Steiner, "all the forces of a child's organization emanate from the neurosensory system. . . . By bringing respiration into harmony with neurosensory activity, we draw the spirit-soul element into the child's physical life."
Peter Selg investigates how children's early experience of the world begins as an undifferentiated sensory relationship to their phenomenological environment. This aspect of a child's incarnation leads to leaning through imitation and to the process of recognizing "the Other" as a separate entity with which to interact.
