Here's what I got from that...
1. Crusie thinks pshycology is quackery.
2. He thinks there is no such thing as a chemical imbalance
3. He says drugs only masks the problems.
4. He says, and Matt agreed, that, ideally, no one should be on drugs in order to live a happy life.
I think he's got some points. I don't know squat about scientology but I do think we're drugging way to many people in our society, especially kids, and I do think part of the problem is not facing problems and fixing them, but masking them with, as Tom almost said, gobbledy gook, and drugs.
