   It should perhaps be noted that, throughout the development of his psychological system, [Carl] Jung demonstrated a remarkable passion for the detection of opposites and their resolution through the constellation of quaternities. Not only are there four psychic functions of thinking, feeling, sensation and intuition, but he pointed to Empedocles' four elements, Hippocrates' four 'humours', the ascending quaternity of anima figures (Eve, Helen, Mary, Sophia), the four figures of the Trinity together with the Virgin Mary, and he frequently quoted the lines from the 'Kabeiroi Scene' of [Johann Wolfgang von] Goethe's Faust II: 'Three we took off beside us, / The fourth of them denied us.'
