“Coincidence is God's way of remaining anonymous.”
The source generally (but falsely) cited is Einstein's The World As I See It http://en.wikipedia.org/wiki/The_World_as_I_See_It_(book) (1949). The quotation is probably a translation of "Der Zufall ist das Pseudonym, das der liebe Gott wählt, wenn er inkognito bleiben will" (attributed to Albert Schweitzer).
