In each of us two powers preside, one male, one female: and in the man's brain, the man predominates over the woman, and in the woman's brain, the woman predominates over the man. If one is a man, still the woman part of the brain must have effect; and a woman also must have intercourse with the man in her. Coleridge perhaps meant this when he said that a great mind is androgynous. It is when this fusion takes place that the mind is fully fertilized and uses all its faculties.
