Expressionism and all other unconventional techniques in drama have only one valid aim, and that is a closer approach to truth. When a play employs unconventional techniques, it is not, or certainly shouldn't be, trying to escape its responsibility of dealing with reality, or interpreting experience, but is actually or should be attempting to find a closer approach, a more penetrating and vivid expression of things as they are. The straight realistic play with its genuine frigidaire and authentic ice cubes, its characters that speak exactly as its audience speaks...has the same virtue of a photographic likeness. Everyone should know nowadays the unimportance of the photographic in art: that truth, life, or reality is an organic thing which the poetic imagination can represent or suggest, in essence, only through transformation, through changing into other forms than those which were merely present in appearance.
These remarks... have to do with a conception of a new, plastic theater which must take the place of the exhausted theater of realistic conventions if the theater is to resume vitality as a part of our culture.
Tennessee Williams, 1945
