"Things are different with Luna: every month she is darkened and extinguished; she cannot hide this from anybody, not even from herself. She knows that this same Luna is now bright and now dark—but who has ever heard of a dark sun? We call this quality of Luna “women's closeness to nature,” and the fiery brilliance and hot air that plays round the surface of things we like to call “the masculine mind."
— Carl Jung, Swiss psychiatrist, born July 26, 1875
