The Invisible Question

Invisibility is not just a question of class or race. When someone lacks direction they seem to drop from view. They float, ghostlike through the world without really impacting anything.

In the book the narrator seems to move from mold to mold without really fitting comfortably into any of them. When he becomes a communist pundit he can't quite comfortably fit into the doctrine and so what shines through to those who hear his speech is the mold not the man within it. Similarly when he becomes a factory worker he is unhappy and unmotivated he is invisible. People only saw a factory worker they did not see the narrator.
