"Joyce was a realist, but his reality was not ours," writes John Gordon in his new book. Here, he maintains that the shifting styles and techniques of Joyce's works is a function of two interacting realities the external reality of a particular time and place and the internal reality of a character's mental state. In making this case Gordon offers up a number of new readings: how Stephen Dedalus conceives and composes his villanelle; why the Dubliners story about Little Chandler is titled "A Little Cloud"; why Gerty MacDowell suddenly appears and disappears; what is happening when Leopold Bloom stares for two minutes on end at a beer bottle's label; why the triangle etched at the center of Finnegans Wake doubles itself and grows a pair of circles; why the next to last chapter of Ulysses has, by far, the book's highest incidence of the letter C; and who is the man in the macintosh.
