Consider the number of young people all over the world who are getting married, day in and day out, for no other reason than that someone of the opposite sex looks well in a green jersey or sings baritone, and then tell me that divorce has reached menacing proportions. The surface of divorce has not even been scratched yet.
—Robert Benchley (1889–1945)
Your pier-glass or extensive surface of polished steel ... will be minutely and multitudinously scratched in all directions; but place now against it a lighted candle as a centre of illumination, and lo! the scratches will seem to arrange themselves in a fine series of concentric circles round that little sun. It is demonstrable that the scratches are going everywhere impartially, and it is only your candle which produces the flattering illusion of a concentric arrangement, its light falling with an exclusive optical selection. These things are a parable. The scratches are events, and the candle is the egoism of any person now absent.
—George Eliot [Mary Ann (or Marian)
