Famous quotes containing the words attack and/or scenarios:
“I’ve seen things you people wouldn’t believe. Attack ships on fire off the shoulder of Orion. I watched seabeams glitter in the dark near the Tennhauser Gate. All those moments will be lost in time like tears in rain. Time to die.”
—David Webb Peoples, U.S. screenwriter, and Ridley Scott. Roy Batty, Blade Runner, final words before dying—as an android he had a built-in life span that expired (1982)
“The taste for worst-case scenarios reflects the need to master fear of what is felt to be uncontrollable. It also expresses an imaginative complicity with disaster.”
—Susan Sontag (b. 1933)
