An excerpt from Harold Pinter's 2005 Nobel Lecture:
In 1958 I wrote the following:
'There are no hard distinctions between what is real and what is unreal, nor between what is true and what is false. A thing is not necessarily either true or false; it can be both true and false.'
I believe that these assertions still make sense and do still apply to the exploration of reality through art. So as a writer I stand by them but as a citizen I cannot. As a citizen I must ask: What is true? What is false?
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.
I believe the search for truth as he describes it here could be applied to more than just drama, or art, and to more than just the search for truth.
