Now I have read this story a few times, even looked at background information and read it again but I can't seem to put my finger on the theme of the story. Roget is clearly obsessed to classify things. He hates disorder, had his mother make him become a doctor and yet not realize what he actually wanted to do. His father died when he was young, he married late and was widowed early, lived one hell of a sad life and so after reading throughout the story I just can't place the theme. Any help from someone who has read/interpreted the story before would be appreciated.
