If he’d been the type

If he’d been the type who evolves theories of political history for his own amusement, he might have said all political events: wars, governments and uprisings, have the desire to get laid as their roots; because history unfolds according to economic forces and the only reason anybody wants to get rich is so he can get laid steadily, with whomever he chooses.

-Thomas Pynchon, in the novel V (p. 198, Bantam Windstone paperback edition, 1963)
