Dave Shaw said...writtenwyrdd, you should read Alicia's book - it covers that particular point and many others very well.
Thanks, Dave! The book is Power of Point of View, by Alicia Rasley, and it's available at Amazon-- http://www.amazon.com/Power-Point-View-Make-Story/dp/1582975248/ref=sr_1_1?ie=UTF8&s=books&qid=1208986849&sr=8-1
So do you want to hear my totally unscientific theory of how POV approach relates to apprehension of reality? Yes? Well, here goes.
I think which POV approach you naturally take connects to the way you view reality.
For example, omniscient writers tend to think that there is an actual external reality that is knowable, if only by a "god" or "author"-- the omniscient narrative persona.
Single-third-POV writers tend to be agnostic on whether there is a knowable reality, because they are far more interested in the internal reality-- what's going on inside a single character and how that person interprets what is happening around him/her. That is, there may or may not be an external absolute reality, but what really matters is how the individual perceives and interprets.
Multiple- POV writers, the most cinematic of all, believe that if reality is knowable, it's only knowable through a collage of viewpoints, no one of which is completely reliable. Only by juxtaposing different views of an event can the reader get any sense of what really happened.
First-person POV writers doubt the existence of a knowable reality. In fact, they doubt their own narrators. They create narrators who are hiding things and lying and deceiving (else might as well go with third person). They're most interested in how "reality" or "events" can be distorted by the lens of viewpoint.
Notice that the last two require active reader participation to understand the meaning of the story events-- with multiple, the reader has to put all the viewpoints together to arrive at some understanding, and with first-person, the reader has to figure out what's true and what's not in the narrative, and what the lies tell about the narrator and the story.
Now I know that most everyone will be thinking, "Huh. The books I've read don't do that." That just means that the writers aren't sufficiently exploring and exploiting the potential of POV. :) But it's there... really. In my theory, anyway! :)
