“There is a close tie of affection between sovereigns and their subjects; and as chaste wives should have no eyes but for their husbands, so faithful liegemen should keep their regards at home and not look after foreign crowns. For my part I like not for my sheep to wear a stranger’s mark nor to dance after a foreigner’s whistle.”
—Elizabeth I (1533–1603)
“The term preschooler signals another change in our expectations of children. While toddler refers to physical development, preschooler refers to a social and intellectual activity: going to school. That shift in emphasis is tremendously important, for it is at this age that we think of children as social creatures who can begin to solve problems.”
—Lawrence Kutner (20th century)
“Napoleon has not been conquered by men. He was greater than any of us. God punished him because he relied solely on his own intelligence until that incredible instrument was so strained that it broke.”
—Jean Baptiste Bernadotte (1763–1844)
