Art must take reality by surprise.
It seems to me that there are two kinds of trickery: the "fronts" people assume before one another's eyes, and the "front" a writer puts on the face of reality.
Of course the illusion of art is to make one believe that great literature is very close to life, but exactly the opposite is true. Life is amorphous, literature is formal.
