Famous quotes containing the words stain and/or hops:
“No more be grieved at that which thou hast done,
Roses have thorns, and silver fountains mud,
Clouds and eclipses stain both moon and sun,
And loathsome canker lives in sweetest bud.
All men make faults, and even I in this,
Authorizing thy trespass with compare,
My self corrupting salving thy amiss,
Excusing thy sins more than thy sins are:”
—William Shakespeare (1564–1616)
“The earth has become small, and on it hops the last man, who makes everything small. His race can no more be exterminated than the flea can be. The last man lives the longest.”
—Friedrich Nietzsche (1844–1900)
