Famous quotes containing the words gray and/or line:
“Chrome: her pretty childface smooth as steel, with eyes that would have been at home at the bottom of some deep Atlantic trench, cold gray eyes that lived under terrible pressure. They say she cooked her own cancers for people who crossed her, rococo custom variations that took years to kill you.”
—William Gibson (b. 1948)
“What we are, that only can we see. All that Adam had, all that Caesar could, you have and can do. Adam called his house, heaven and earth; Caesar called his house, Rome; you perhaps call yours, a cobbler’s trade; a hundred acres of ploughed land; or a scholar’s garret. Yet line for line and point for point, your dominion is as great as theirs, though without fine names. Build, therefore, your own world.”
—Ralph Waldo Emerson (1803–1882)
