"I Am a Strange Loop" by the same guy covers the same concepts, albeit without the whimsey or color.
(I also enjoyed Joyce the one time I read him, so it's possible that I can just appreciate a good slog...)
But the whims and color were the best things about the book!
I also appreciate that I learned a lot of tangential things mentioned in the book that had nothing to do with the mind or consciousness.
