Famous quotes containing the words alternative, star and/or systems:
“If the alternative is to keep all just men in prison, or give up war and slavery, the State will not hesitate which to choose.”
—Henry David Thoreau (1817–1862)
“Never tell me that not one star of all
That slip from heaven at night and softly fall
Has been picked up with stones to build a wall.”
—Robert Frost (1874–1963)
“What is most original in a man’s nature is often that which is most desperate. Thus new systems are forced on the world by men who simply cannot bear the pain of living with what is. Creators care nothing for their systems except that they be unique. If Hitler had been born in Nazi Germany he wouldn’t have been content to enjoy the atmosphere.”
—Leonard Cohen (b. 1934)
