All the world's a stage,

 And all the men and women merely players;

 They have their exits and their entrances,

 And one man in his time plays many parts,

His acts being seven ages.
william shakespeare

But now I have come to believe
that the whole world is an enigma,
a harmless enigma that is made terrible
by our own mad attempt to interpret it
as though it had an underlying truth.
