h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I've been reading some on how children's minds develop, and I've found something interesting. The book I have talks some about Lawrence Kohlberg, a psychologist who did some studies on children/young adults and about how they develop morality. He says that there are 3 levels, and the last level is "post-conventional thinking," and the book that I read says that Kohlberg thought that only a minority of adults reach this stage, and that they are nearly always at or above age 20. And, I quote, "They [post-con. people] accept that laws have to be upheld but there are exceptional circumstances, reasons of principle where it is acceptable to break the law for moral reasons." Um, I know a lot of people who are at that stage, myself included. I'm 20, and I have been in this level of morality for quite some time, and I know that in my high school there were A LOT of students who were in this level. But, I wonder how old this study is, and how normal my high school was. Everyone at my school cared about their studies, which I know doesn't normally happen in a public school. I also have not read too far past the author explaining what Kohlberg said, so I might not have gotten the whole point yet.

I'm also reading Anne McCaffery now. I read most of the Pern books a year ago, but I had to stop reading them because of college. So, I'm starting all of the books over again. Fun!
