Narrators, Part 2 -- The Cess of Omniscience
At the end of a work of fiction, the ideal reader knows as much as the author. How could it be otherwise? There is nothing else to know.
This means that the end of the work is the end of omniscience.
Thackeray
Narrators, Part 1 -- How can you know it's third person?
When I was a kid I hated what I called I-books, first person narratives. It was not only that there was something unseemly about people telling the kinds of stories I liked (genre: heroic, adventurous, courageous) about themselves. There was also something just a little bit viscerally off-putting about them.
