Aspects of geography are important in relation to the establishment of body ego, since they inevitably supply from the external world the early symbols that represent in the mind the basic elements of infantile experience in regard to body parts, functions, and relationships with primal objects.

These conflicts center on the developmentally evolving meanings of the mother's body as epitomized in the riddle of the Sphinx. Illustration of the concepts includes a brief clinical report and selected literary and mythological examples.
