Pasolini wished to bring to the attention of the public the existence of this underground class they thought extinct. As he saw it, "They were thought of as a closed book. Yet, poor devils, they really did exist". He wrote the book in lowbrow language and derogatory slang that the real life "
lumpen proletariat" would use. It made the book difficult for mainstream readers, the reading public that Pasolini opposed. He later wrote in
Heretical Empiricism that literature should be "written in a language substantially different from that of the writer, not leaving out of consideration a certain naturalism". Another alienating characteristic of the book is the fact that the narrator does not provide any background information for readers unfamiliar with the social setting of his story. His narration puts himself on the same level as his characters. He does not narrate from above. He saw the underground class as the only ones who survived the corruption brought about of industrialization and modernity, a sort of human time capsule, the only ones who are truly free. He respects them for this and sees them as the true underclass that even the
Communist Party looks down on. ==Significance==
