The Theatre of the Absurd ... can be seen as the reflection of what seems to be the attitude most genuinely representative of our own time.  The hallmark of this attitude is its sense that the certitudes and unshakable basic assumptions of former ages have been swept away, that they have been tested and found wanting, that they have been discredited as cheap and somewhat childish illusions. The decline of religious faith was masked until the end of the Second World War by the substitute religions of faith in progress, nationalism, and various totalitarian fallacies. All this was shattered by the war.
