After reading just one chapter of Invisible Man, I’m risking it all and stating what I think will be themes in the novel: darkness and light–with variations including blindness (or being blindfolded)
Chapter 1 is a doozy. There’s the battle royal and other incidents that I prefer not to discuss on our PG rated blog. Did you focus on the darkness? The narrator says “I was unused to darkness” as he’s blindfolded and forced to brawl.
Perhaps I have insight or perhaps I took the prologue as a huge hint. Remember the narrator’s lightbulb style of home decorating? Yes, I’m quite confident that darkness and light are themes in this classic.
