“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)

“We are, I know not how, double within ourselves, with the result that we do not believe what we believe, and we cannot rid ourselves of what we condemn.”
—Michel de Montaigne (1533–1592)
