Famous quotes containing the words optimal and/or rulers:
“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)
“They lived under a just and moderate government, and they admitted that one bond of their fidelity was that their rulers were the better men.”
—Titus Livius (Livy)
