Famous quotes containing the words common, laboratory and/or stains:
“What climbs the stair?
Nothing that common women ponder on
If you are worth my hope! Neither Content
Nor satisfied Conscience, but that great family
Some ancient famous authors misrepresent,
The Proud Furies each with her torch on high.”
—William Butler Yeats (18651939)
“The best work of artists in any age is the work of innocence liberated by technical knowledge. The laboratory experiments that led to the theory of pure color equipped the impressionists to paint nature as if it had only just been created.”
—Nancy Hale (b. 1908)
“I cannot assent to a measure which stains our credit. We must keep that untainted. We are a debtor nation. Low rates of interest on the vast indebtedness we must carry for many years, is the important end to be kept in view. Expediency and justice both demand honest coinage.”
—Rutherford Birchard Hayes (18221893)
