### Famous quotes containing the word relation:

“The instincts of the ant are very unimportant, considered as the ant’s; but the moment a ray of *relation* is seen to extend from it to man, and the little drudge is seen to be a monitor, a little body with a mighty heart, then all its habits, even that said to be recently observed, that it never sleeps, become sublime.”

—Ralph Waldo Emerson (1803–1882)

“You know there are no secrets in America. It’s quite different in England, where people think of a secret as a shared *relation* between two people.”

—W.H. (Wystan Hugh)

“Every word was once a poem. Every new *relation* is a new word.”

—Ralph Waldo Emerson (1803–1882)
