Isolation is a theme much present in the story line since throughout almost the entire story Brian is found stranded and alone. Brian is completely isolated from the rest of the world physically and mentally and therefore we only had his thoughts to be our understanding of what was happening. For example, we were able to see the thought process of the many intents Brian made to build a fire. The reader is then able to learn that you can build a fire from creating sparks with metal, your breath, and flammable material like paper; almost as if you were in Brian’s shoes.
