    I think it's clear that Alex simply jumped too quickly to a conclusion --and not out of malice but out of sheer enthusiasm for the subject. I'm reminded of a famous navigator who believed that he had found an error in his table of logarithms, and that this was something that he "could prove beyond a doubt". It happens to everyone. We make little errors and find ways to justify them. And there's nothing "ivory tower" about it!

    Some words to live by:
