Famous quotes containing the word necessity:
“We are sure that, though we know not how, necessity does comport with liberty, the individual with the world, my polarity with the spirit of the times. The riddle of the age has for each a private solution.”
—Ralph Waldo Emerson (1803–1882)
“The necessity of labor and conversation with many men and things to the scholar is rarely well remembered.”
—Henry David Thoreau (1817–1862)
“The necessity of poetry has to be stated over and over, but only to those who have reason to fear its power, or those who still believe that language is “only words” and that an old language is good enough for our descriptions of the world we are trying to transform.”
—Adrienne Rich (b. 1929)
