The story is a semi-autobiography of sorts, following the relationship between Von Humboldt Fleischer and Charlie Citrine. Humboldt is modeled on Bellow's friend Delmore Schwartz, and Citrine is based on Bellow himself. The plot seems almost like an afterthought, with the main focus being on Citrine's daily life in 1970s Chicago and his reminiscences about Humboldt.
The argument for "Humboldt's Gift" being a classic is that it won the 1976 Pulitzer Prize and the Nobel Prize for literature that same year. It is also a textbook example of Postmodernism, with its thoughtful, self-referential, and slyly funny nature. The language is beautiful, and it focuses on character rather than plot.
However, there are also arguments against it being a classic. Some readers find it to be an overwritten mess, an example of academic navel-gazing. They argue that it was part of the reason why novels lost their dominance in society, as academes took over the literary industry with their "deconstructionism" and "metafiction."
My verdict is that while I personally adored "Humboldt's Gift" as an overeducated intellectual and fellow Chicagoan, I can also understand the complaints of those who found it a chore to read. It is a perfect example of both the good and bad aspects of Postmodernism. It is intelligent and charming, but it also serves as a bad premonition of things to come. Therefore, I do not consider it a classic and recommend it only to fans of Postmodernist masters. In conclusion, "Humboldt's Gift" is a complex and controversial work that will continue to be debated by readers and critics alike. Whether or not it is a classic depends on one's perspective and personal taste.
