Why do you think Paulson chose to use Brian's third limited point of view rather than either Brian's first person point of view or a third person objective point of view?

Paulson's choice of a third limited point of view for Hatchet succeeds on several levels. Yet this choice poses two distinct questions. Why not the first person, and why not the third person objective? 
The power in this book is the capacity for the reader to feel akin to Brian's situation and actions; to feel as closely tied to Brian in this moment as possible. This makes the reader feel as though they are trapped in the Canadian wilderness, having to tackle the unknown challenges of each grueling day. Were the story written from the third person objective point of view, none of Brian's thoughts or feelings would be transmitted in the narrative. Especially considering the absence of dialogue in this book, that would utterly deaden the empathy the reader feels for Brian. When the book describes Brian's fear, anger, and doubt, the reader can feel it too, is further drawn into the story. 
If Brian's thoughts and feelings are so important, why not just use the first person point of view? The reader does not read from Brian's direct thoughts and experiences, but watches him and his struggles in the third-person. Though it seems contradictory, this point of view also instills more empathy in the reader than if it were a first-person point of view. If Brian were telling the story, the reader would feel as though they are Brian, and Brian is in charge. Looking at Brian as a separate entity heightens his loneliness, his isolation, and creates a tension for young readers: they are their own person, simply watching Brian, and they cannot help him. 
In a way, the method of third-person limited point of view in this book is an exercise in moderation. The author gives insight into Brian's thoughts and feelings, but not enough insight to see the bigger picture, including any clear sign that Brian will eventually be saved. The author's point of view gives enough information to feel drawn in but not so much information that the reader feels detached and knowledgeable about this story. Just as Brian suffers and wonders what will happen, so too must the reader.
