I have Enda Duffy's The Subaltern Ulysses from UCC Library. I intend to look for possible arguments or thesis ideas in his works, and perhaps I can see if there is a connection here between Wollaeger's mention of Spivak's subaltern argument.

A subaltern is basically someone in a subordinate position/social status, but not so basically, it's also used in postcolonial studies, including by Spivak, who merges feminism and postcolonial studies in "Can the Subaltern Speak?"
