Famous quotes containing the words warning and/or signs:

By night thy silent signal lamps to swing.”

“The good of a book lies in its being read. A book is made up of signs that speak of other signs, which in their turn speak of things. Without an eye to read them, a book contains signs that produce no concepts; therefore it is dumb.”
—Umberto Eco (b. 1932)
