Famous quotes containing the words extension and/or ladder:
“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)
“O, when degree is shaked,
Which is the ladder to all high designs,
The enterprise is sick.”
