Psyche's Knife examines the myth of Eros and Psyche as a metaphor for the development of soul in the psychology of women, explicating the tropes of love and power as depicted by Psyche's use of a knife in attempting to learn the identity of her lover. Nelson examines the metaphor of the knife from all angles--alchemical, sacrificial, lunar, phallic--and delves into the mythology and imagery of women and knives, connecting our deep past to our present lives and our possibilities for the future.
