“The Germans—once they were called the nation of thinkers: do they still think at all? Nowadays the Germans are bored with intellect, the Germans distrust intellect, politics devours all seriousness for really intellectual things—Deutschland, Deutschland Über alles was, I fear, the end of German philosophy.”

“In the most desirable conditions, the child learns to manage anxiety by being exposed to just the right amounts of it, not much more and not much less. This optimal amount of anxiety varies with the child’s age and temperament. It may also vary with cultural values.... There is no mathematical formula for calculating exact amounts of optimal anxiety. This is why child rearing is an art and not a science.”
—Alicia F. Lieberman (20th century)
