Famous quotes containing the words extension and/or property:
“The motive of science was the extension of man, on all sides, into Nature, till his hands should touch the stars, his eyes see through the earth, his ears understand the language of beast and bird, and the sense of the wind; and, through his sympathy, heaven and earth should talk with him. But that is not our science.”
—Ralph Waldo Emerson (1803–1882)
“We do not deride the fears of prospering white America. A nation of violence and private property has every reason to dread the violated and the deprived.”
—June Jordan (b. 1939)
