- Is Bartleby merely a lazy person who decides he no longer wants to work? And in this way does the story show what happens to people who isolate themselves from the world? (a variation on the theme present in "The Fall of the House of Usher").
- Is Bartleby a kind of victim? Is he someone who, through years of dehumanizing and monotonous work, has been turned into a human machine, and the story shows what happens when such a machine malfunctions?
- Is Bartleby a kind of failed industrial, modernized romantic hero? In this sense, his romantic self has been so battered and oppressed by years and years of dehumanizing labor that the only thing left is a tiny, mouse-like "I'd prefer not to." At some point he is described as being "like the last column of some ruined temple." Maybe Bartleby's "I'd prefer not to" functions as the last death rattle of romantic expression, Whitman's "Yawp" reduced to a faint cry of self-assertion just before the grave. Yeah? Maybe???
All food for thought. You might have an entirely different idea. The main question I want you to get at is... What's wrong with Bartleby?
