Thanks for the comments, Paul. Just a brief note right now: I do think that whatever you want to call what Wolfram has done in his book, it really is as import as what Darwin did in his. If it seemed otherwise, I just wanted to show that we show look at all claims with some skepticism, but be prepared to accept them no matter how they are packaged, or who says them. We got a peek yesterday that science is not just a bland mechanical process, but there are real people "doing it" and each of them have personalities, egos, lives, etc. To me, if something "account[s] for all known phenomena", then there is something very "real" about it, whatever we mean by "real". I may believe that I am heading for the "truth"; you maybe "getting it less wrong". Either way, we still do the same kind of science every day. Finally, take a look at: http://bubo.brynmawr.edu/~dblank/images/ant.jpg More later...
