Famous quotes containing the words high, visibility and/or signals:
“Let the saints be joyful in glory: let them sing aloud upon their beds. Let the high praises of God be in their mouth, and a two-edged sword in their hand; to execute vengeance upon the heathen, and punishments upon the people; to bind their kings with chains and their nobles with fetters of iron; to execute upon them the judgment written.”
—Bible: Hebrew Psalms 149:5-9.
“My children have taught me things. Things I thought I knew. The most profound wisdom they have given me is a respect for human vulnerability. I have known that people are resilient, but I didn’t appreciate how fragile they are. Until children learn to hide their feelings, you read them in their faces, gestures, and postures. The sheer visibility of shyness, pain, and rejection let me recognize and remember them.”
—Shirley Nelson Garner (20th century)
“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)
