Famous quotes containing the word groups:
“Women over fifty already form one of the largest groups in the population structure of the western world. As long as they like themselves, they will not be an oppressed minority. In order to like themselves they must reject trivialization by others of who and what they are. A grown woman should not have to masquerade as a girl in order to remain in the land of the living.”
—Germaine Greer (b. 1939)
“Trees appeared in groups and singly, revolving coolly and blandly, displaying the latest fashions. The blue dampness of a ravine. A memory of love, disguised as a meadow. Wispy cloudsthe greyhounds of heaven.”
—Vladimir Nabokov (18991977)
“Only the groups which exclude us have magic.”
—Mason Cooley (b. 1927)
