Sigmund Freud skriver til sin venn Wilhelm Fliess i Berlin (her gjengitt i engelsk oversettelse -- originalen er på tysk):
"Recently at the College of Physicians Breuer gave a big speech in my honor and introduced himself as a converted adherent to the sexual etiology. When I thanked him for this in private, he spoiled my pleasure by saying, "But all the same, I don't believe it."
Do you understand this? I don't. "
