Apparently no one has read Finnegans Wake in its entirety. It took Joyce, who is said to have had the greatest English vocabulary which has ever existed, almost 20 years to write a book which he deliberately made abstruse to the point of pretty much inventing his own dialect of English. Unless you have some sort of obsessive compulsive disorder (as Joyce probably did) which drives you to spend a decade or so of your life trying to decrypt it, is there any point in trying to read it?
