@aaronssongs,
Underground Man: The central figure, indeed the anti-hero, of Notes from the Underground, is the Underground Man. It's important to note that although the UM shares many of Dostoevsky's own viewpoints about romanticism, the enlightenment and other issues, the author and his character must be clearly separated. Dostoevsky himself alludes to this in his prologue. Though the UM says that his liver is diseased, the reader soon learns that the UM's illness is more than physical: indeed it's a psychological disease-he is hyperconscious. He admits that day after day he rushes home to hide in his "corner," only to anguish and "gnaw" at himself, reconsidering the actions he has taken that day. At the same time, however, he finds a kind of pleasure in the humiliation and even despair caused by this "overly acute consciousness."
Indeed........a small, angry, bitter, outcast of a man, hiding in the shadows of society, harboring sinister thoughts and intentions about it he's too weak to act on.
