A great deal of nonsense is written every day about characters in fiction - from the side of those who believe too much in character and from the side of those who believe too little. Those who believe too much have an iron set of prejudices about what characters are:we should get to "know" them; they should not be "stereotypes;" they should have an"inside" as well as an outside, depth as well as surface; they should "grow" and " develop", and they should be nice. So they should be pretty much like us.
