Famous quotes containing the words voice, frequency, primary, patch and/or bay:
“The only true madness is loneliness,
the monotonous voice in the skull
that never stops
because never heard.”
—John Montague (b. 1929)
“One is apt to be discouraged by the frequency with which Mr. Hardy has persuaded himself that a macabre subject is a poem in itself; that, if there be enough of death and the tomb in one’s theme, it needs no translation into art, the bold statement of it being sufficient.”
—Rebecca West (1892–1983)
“The traditional American husband and father had the responsibilities—and the privileges—of playing the role of primary provider. Sharing that role is not easy. To yield exclusive access to the role is to surrender some of the potential for fulfilling the hero fantasy—a fantasy that appeals to us all. The loss is far from trivial.”
—Faye J. Crosby (20th century)
“Imperious Caesar, dead and turned to clay,
Might stop a hole to keep the wind away.
O that that earth which kept the world in awe
Should patch a wall t’expel the winter’s flaw!”
—William Shakespeare (1564–1616)
“Three miles long and two streets wide, the town curls around the bay ... a gaudy run with Mediterranean splashes of color, crowded steep-pitched roofs, fishing piers and fishing boats whose stench of mackerel and gasoline is as aphrodisiac to the sensuous nose as the clean bar-whisky smell of a nightclub where call girls congregate.”
—Norman Mailer (b. 1923)
