“In the twentieth century, death terrifies men less than the absence of real life. All these dead, mechanized, specialized actions, stealing a little bit of life a thousand times a day until the mind and body are exhausted, until that death which is not the end of life but the final saturation with absence.”
—Raoul Vaneigem (b. 1934)
“Life will show you masks that are worth all of your carnivals.”
—Ralph Waldo Emerson (1803–1882)
“And ye shall hear of wars and rumours of wars: see that ye be not troubled: for all these things must come to pass, but the end is not yet. For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places.”
—Bible: New Testament Jesus, in Matthew, 24:6-7.
“Just opening up the door, having this ordinary person fly, says a lot for the future. You can always equate astronauts with explorers who were subsidized. Now you are getting someone going just to observe. And then you’ll have the settlers.”
—Christa McAuliffe (1948–1986)
