Names generate meaning in a short amount of space — they provoke thoughts, questions. That's something I like doing. Of course, you have to be careful. Sometimes it can alienate the reader, it can be another level of mediation, to make a character carry the great burden of a metaphoric name. The character can be a device before he or she becomes a person, and that can be a bad thing for a writer who wants to offer up a kind of emotional proximity in the work. It's a constant struggle, the desire to be playful and the desire to communicate on some very stark emotional level.
It's very difficult to lie to yourself about certain things. I'm not necessarily convinced about how information is gathered and I don't think the credence that's given to it is valid.
