Famous quotes containing the words lighter and/or air:
“The problem of the twentieth century is the problem of the color-line—the relation of the darker to the lighter races of men in Asia and Africa, in America and the islands of the sea. It was a phase of this problem that caused the Civil War.”
—W.E.B. (William Edward Burghardt)
“I wonder whether mankind could not get along without all these names, which keep increasing every day, and hour, and moment; till at the last the very air will be full of them; and even in a great plain, men will be breathing each other’s breath, owing to the vast multitude of words they use, that consume all the air, just as lamp-burners do gas.”
—Herman Melville (1819–1891)
