Grinberg traces the concept of curiosity through all its vicissitudes. The relationship of curiosity to the child's need to explore the mother's body is one of the genetic elements emphasized. Since the author has had an opportunity to analyze a number of physicians, she postulates that the wish to know what is inside the mother's body might be connected with the drive to become a physician. She does not elaborate this point and has not had a surgeon in analysis, from whom the idea might be more clearly evident. However, phallic, anal, and other aspects of the concept are well described, as are the ego elements involved in the object imago.
