I am speaking of the modernists, of course, from Pirandello to Joyce. But the modernists still had a sense of something beneath them, even if they sensed that solidity below might be illusory. Because of that, their relativism was contained, in a way, by the real world. Post-modernists instead had to deal with a present void, the horrors of what had happened, a nothingness beneath that threatened to devour our precarious existence above. So lightness, ‘leggerezza’, as the Italians say, became an important theme in post-modernism, in contrast to ‘heavy’, certain characters and contexts. If the world itself could disappear, what is it we live in?
