Famous quotes containing the words earth and/or materials:
“Let Rome in Tiber melt and the wide arch
Of the ranged empire fall! Here is my space.
Kingdoms are clay; our dungy earth alike
Feeds beast as man. The nobleness of life
Is to do thus; when such a mutual pair
And such a twain can do ‘t, in which I bind,
On pain of punishment, the world to weet
We stand up peerless.”
—William Shakespeare (1564–1616)
“He was no specialist except in the relation of things.... He took most of his materials at second hand.... But no matter who mined the gold, the image and superscription are his.”
—Woodrow Wilson (1856–1924)
