Famous quotes containing the word necessity:
“Our good schools today are much better than the best schools of yesterday. When I was your age and a pupil in school, our teachers were our enemies.
Can any thing ... be more painful to a friendly mind, than a necessity of communicating disagreeable intelligence? Indeed it is sometimes difficult to determine, whether the relator or the receiver of evil tidings is most to be pitied.”
—Frances Burney (1752–1840)
“The sadness of the women’s movement is that they don’t allow the necessity of love. See, I don’t personally trust any revolution where love is not allowed.”
—Maya Angelou (b. 1928)
“For us necessity is not as of old an image without us, with whom we can do warfare; it is a magic web woven through and through us, like that magnetic system of which modern science speaks, penetrating us with a network subtler than our subtlest nerves, yet bearing in it the central forces of the world.”
—Walter Pater (1839–1894)
