These come from the second section of Gravity's Rainbow, by Thomas Pynchon. The section, called Un Perm' au Casino Hermann Goering (a soldier on leave at the Hermann Goering casino) shifts from an endless hedonistic chaotic party at a French resort into a world of manipulation and fear. The main character, Theodore Slothrop has all of his identification papers stolen and is passed around from one shady character to another. As he decends into abject paranoia, he learns the lessons of each of these proverbs.
