Famous quotes containing the words soft, active and/or galactic:
“The thundering line of battle stands,
And in the air Death moans and sings:
But Day shall clasp him with strong hands,
And Night shall fold him in soft wings.”
—Julian Grenfell (1888–1915)
“Things happen to us, all the time. It was like that for a century, and it is again. It’s not like here: People always do things, because you are born with it; you are brought up in this spirit, the active approach to life: “Stand up and go.” We were not. We were always passive in our lives.”
—Natasha Dudinska (b. c. 1967)
“In sci-fi convention, life-forms that hadn’t developed space travel were mere prehistory—horse-shoe crabs of the cosmic scene—and something of the humiliation of being stuck on a provincial planet in a galactic backwater has stayed with me ever since.”
—Barbara Ehrenreich (b. 1941)
