Joyce’s mode of punning is synthetic– proceeding by the concretion of words within words based on the basic logic of homophony.
The puns proceed like imagistic-collages. Think John Cage’s “Imaginary Landscapes” of tape-collage. When I read, I try to create unfolding fields of meaning, imagistically, among other ways of feeling one’s way through the text. It’s not unlike experimenting with cognitive dissonance, a la Duchamp’s “Anemic Cinema.”
So, for example, a found-image interpretation of an early sentence from FW.
“Sir Tristram, violer d’amores,”
Making collages like this is a fun way to proceed. If you so choose, read a few pages, find a juicy pun, hemorrhaging with meanings, like a palmofgranite, and make a field for it (sound collages are also a possibility–or computer programming or flow-proofs in non-euclidean geometry). If a method like this isn’t too constricting.
