What narrative perspective is found in Orwell's Animal Farm?
I would say that the narration in this story is third person and is unobtrusive, objective, and limited.
The narration is third person because the narrator is not a character. The narrator does not say "I saw this..." or "I heard that."
The narration is unobtrusive, objective and limited because it is just looking at the characters from outside of themselves, not really knowing what they are thinking, necessarily. The narration reports mainly just actions, not thoughts. It does not claim to know what the charcters are thinking. Finally, it does not take the point of view of any of the characters.
The narrative is third person.
The power in this narrative is that it tells exactly what is reported to the animals without judgment. As readers, it forces us to see the propaganda, the satire and the fallacy for what it is. It doesn't point it out to us, it leads us to the conclusion.
This makes an author very powerful because it gives the reader some creative responsibility in the story. It causes the reader to think, not just digest.
