"Truth in drama is forever elusive. You never quite find it but the
search for it is compulsive. The search is clearly what drives the
endeavour. The search is your task. More often than not you stumble
upon the truth in the dark, colliding with it or just glimpsing an
image or a shape which seems to correspond to the truth, often without
realising that you have done so. But the real truth is that there
never is any such thing as one truth to be found in dramatic art.
There are many. These truths challenge each other, recoil from each
other, reflect each other, ignore each other, tease each other, are
blind to each other. Sometimes you feel you have the truth of a moment
in your hand, then it slips through your fingers and is lost."

-- Harold Pinter (Nobel Prize lecture)
