Famous quotes containing the word throat:
“Superstition, bigotry and prejudice, ghosts though they are, cling tenaciously to life; they are shades armed with tooth and claw. They must be grappled with unceasingly, for it is a fateful part of human destiny that it is condemned to wage perpetual war against ghosts. A shade is not easily taken by the throat and destroyed.”
—Victor Hugo (1802–1885)
