### Famous quotes containing the words sign and/or equals:

“He had that curious love of green, which in individuals is always the *sign* of a subtle artistic temperament, and in nations is said to denote a laxity, if not a decadence of morals.”

—Oscar Wilde (1854–1900)

“I repeat, sir, that in whatever position you place a woman she is an ornament to society and a treasure to the world. As a sweetheart, she has few *equals* and no superiors; as a cousin, she is convenient; as a wealthy grandmother with an incurable distemper, she is precious; as a wet-nurse, she has no equal among men. What, sir, would the people of the earth be without woman? They would be scarce, sir, almighty scarce.”

—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
