Bloom’s quirky questions and final comment, “if we were all suddenly somebody else,” reveal his genuine curiosity about other people’s perspectives and experiences. Of course, Joyce’s strategy as an author is precisely to dig into other people’s lives, feelings, and thoughts in order to present a composite view of the world from multiple perspectives. But this is only possible in literature—never in reality. Bloom also realizes that his curiosity violates social norms. Clearly, Joyce is interested in showing how such norms are artificial, and people are constantly violating and ignoring them in their minds. The man in the macintosh is one of the enduring mysteries in
Ulysses—Joyce chooses never to identify him, and he could represent anyone or anything. (One popular theory is that he's James Joyce himself, and another popular theory is that he's a red herring, inserted in the novel to send readers on wild goose chases.)
