Famous quotes containing the words message and/or structure:
“The whole idea of image is so confused. On the one hand, Madison Avenue is worried about the image of the players in a tennis tour. On the other hand, sports events are often sponsored by the makers of junk food, beer, and cigarettes. What’s the message when an athlete who works at keeping her body fit is sponsored by a sugar-filled snack that does more harm than good?”
—Martina Navratilova (b. 1956)
“What is the structure of government that will best guard against the precipitate counsels and factious combinations for unjust purposes, without a sacrifice of the fundamental principle of republicanism?”
—James Madison (1751–1836)
