What are the motifs in The Recognitions a Novel by William Gaddis?

Through the characters, the novel raises then question whether creativity in the pursuit of fakery is any less important than creativity for the purpose of making unique works of art. For example Herschel concocts phony interviews with celebrities and sells them to fan magazines; he justifies this by thinking that his work, whether genuine of false, brings pleasure to readers and money for himself. Valentine collects art and sells forgeries but rationalizes it by convincing himself that purchasers derive satisfaction from believing they have acquired a timeless masterpiece, whether it's genuine or fake.
