Famous quotes containing the words solar system, leaving, solar and/or system:
“The solar system has no anxiety about its reputation, and the credit of truth and honesty is as safe; nor have I any fear that a skeptical bias can be given by leaning hard on the sides of fate, of practical power, or of trade, which the doctrine of Faith cannot down-weigh.”
—Ralph Waldo Emerson (1803–1882)
“The mere fact of leaving ultimate social control in the hands of the people has not guaranteed that men will be able to conduct their lives as free men. Those societies where men know they are free are often democracies, but sometimes they have strong chiefs and kings. ... they have, however, one common characteristic: they are all alike in making certain freedoms common to all citizens, and inalienable.”
—Ruth Benedict (1887–1948)
“Senta: These boats, sir, what are they for?
Hamar: They are solar boats for Pharaoh to use after his death. They’re the means by which Pharaoh will journey across the skies with the sun, with the god Horus. Each day they will sail from east to west, and each night Pharaoh will return to the east by the river which runs underneath the earth.”
—William Faulkner (1897–1962)
“The United States is unusual among the industrial democracies in the rigidity of the system of ideological control—”indoctrination” we might say—exercised through the mass media.”
—Noam Chomsky (b. 1928)
