Pregnancy demonstrates the deterministic character of woman's sexuality. Every pregnant woman has body and self taken over by a chthonian force beyond her control. In the welcome pregnancy, this is a happy sacrifice. But in the unwanted one, initiated by rape or misadventure, it is a horror. Such unfortunate women look directly into nature's heart of Darkness. For a fetus is a benign tumor, a vampire who steals in order to live. The so-called miracle of birth is nature getting her own way.
