It is as if the savage tribe, instead of finding two bars of iron to play with, had found scattering the seashore fiddles, flutes, saxophones, trumpets, grand pianos by Erhard and Bechstein, and had begun with incredible energy, but without knowing a note of music, to hammer and thump upon them all at the same time.

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.
