What kinds of ideas were explored in post-WWII literature (the period after the atomic bombing of Hiroshima)?I have to visually represent the ideas...

In the post world war ii literature, the sense of doom initiated by the first took on a more permeated and almost fatalistic turn and the themes of fragmentation, devaluation, chaos, pessimism, absurdity, desolation and despair defined the moods of the literary output. The incredulity towards the metanarrative or the grand-narrative which Lyotard calls the defining feature of the postmodern was all over the place with the disillusionment with the humanist premises of nobility and peace.

The chaotic connotations of the Theatre of the Absurd or the Theatre of Panic or Artaud's Theatre of Cruelty are important expressions of this temper. As Agamben has shown us now, another important trait of this era was the testimonial literature of the Jewish people who had to go through all the nightmares of the concentration camp. Adorno called for an intellectual investigation and soul-searching by raising the question--can there be poetry after the Auschwitz?

To take an instance, we can think of Samuel Beckett's play Endgame and the way it implicitly builds on the neuclear disaster without a single particular reference to the bomb or the explosion. The post-holocaust art in this way absorbed the chaotic experiences into its bodily form, way beyond mere representation.
