Famous quotes containing the words famous, mural and/or instruments:
“In a famous Middletown study of Muncie, Indiana, in 1924, mothers were asked to rank the qualities they most desire in their children. At the top of the list were conformity and strict obedience. More than fifty years later, when the Middletown survey was replicated, mothers placed autonomy and independence first. The healthiest parenting probably promotes a balance of these qualities in children.”
—Richard Louv (20th century)
“And each of the huge white creatures was huger than fourscore men;
The tops of their ears were feathered, their hands were the claws of birds,
And, shaking the plumes of the grasses and the leaves of the mural glen,
The breathing came from those bodies, long warless, grown whiter than curds.”
—William Butler Yeats (1865–1939)
“I rejoice that America has resisted. Three millions of people, so dead to all the feelings of liberty, as voluntarily to submit to be slaves, would have been fit instruments to make slaves of the rest.”
—William Pitt, The Elder, Lord Chatham (1708–1778)
