Famous quotes containing the word expressions:
“We ought to celebrate this hour by expressions of manly joy. Not thanks, not prayer seem quite the highest or truest name for our communication with the infinite,—but glad and conspiring reception,—reception that becomes giving in its turn, as the receiver is only the All-Giver in part and infancy.”
—Ralph Waldo Emerson (1803–1882)
“Its idea of “production value” is spending a million dollars dressing up a story that any good writer would throw away. Its vision of the rewarding movie is a vehicle for some glamour-puss with two expressions and eighteen changes of costume, or for some male idol of the muddled millions with a permanent hangover, six worn-out acting tricks, the build of a lifeguard, and the mentality of a chicken-strangler.”
—Raymond Chandler (1888–1959)
“Those expressions are omitted which can not with propriety be read aloud in the family.”
—Thomas Bowdler (1754–1825)
