I first read this when I was 16, and it changed my life, giving me a whole new take on history and psychology and even math. I even tried a year as a psych major in college to see if the statistical approach was really the answer. Forty years later, I read it again, just to see what effect it would have. What I noticed was that the plot was carefully staged and not "fair" (in that the writer often kept some secret informaiton up his sleeve that the reader didn't know, but still it was a good read, and it reminded me of a time when a lot of us believed that science would eventually solve all our problems. It's a classic anyway, and worth devling into. Now on to the rest of the series.
