God does not play dice with the universe: He plays an ineffable game of His 
own devising, which might be compared, from the perspective of any of the 
other players  i.e. everybody , to being involved in an obscure and complex 
variant of poker in a pitch-dark room, with blank cards, for infinite 
stakes, with a Dealer who won't tell you the rules, and who *smiles all the 
time*. 
        -- (Terry Pratchett & Neil Gaiman, Good Omens)
