Famous quotes containing the words active, noise and/or control:
“Play is a major avenue for learning to manage anxiety. It gives the child a safe space where she can experiment at will, suspending the rules and constraints of physical and social reality. In play, the child becomes master rather than subject.... Play allows the child to transcend passivity and to become the active doer of what happens around her.”
—Alicia F. Lieberman (20th century)
“With the noise of the mourning of the Swattish nation!
Fallen is at length
Its tower of strength;
Its sun is dimmed ere it had nooned;
Dead lies the great Ahkoond,
The great Ahkoond of Swat
Is not!”
—George Thomas Lanigan (1845–1886)
“Who can control his fate?”
—William Shakespeare (1564–1616)
