I have gotten a few private questions about this list's charter, so I thought I'd best make a brief statement. This very new Symposium is open to discussion of any and all issues that relate to the pre-agricultural lifestyle pattern for humans. The assumption is that you know enough about the subject to pose intelligent questions or give reasonably authoritative answers, but otherwise discussion -can- be in any area desired. Indeed, I hope that discussion turns at some point to issues like exercise, ethics, and biosustainability. Not that there is any hurry; I just want to avoid anyone getting the impression that diet is the only -allowed- subject because it -happens- to be all that anyone is discussing at the moment. There is a greek word, "nomos," which refers to the concept of spontaneous order--that is, when anarchy somehow generates order. It's a concept implicit in Adam Smith's free market economic theories, for example, and also to the theory of evolution. A mailing list like this one operates under similar principles, and might even be considered as a living organism. It has certain set limitations and patterns, but what happens within those parameters is rarely more than moderately predictable. If discussion stays focused on any one topic, that will be solely because no member has chosen to bring anything else up. There is nothing wrong with that, because whatever the group finds stimulating or enlightening is perfectly acceptable. But if anyone should ever wish to turn the beast in a different direction, he need only do one thing: post a message about a different subject. If the beast doesn't turn the first time, a little patience and further prodding should produce the desired result. (Just don't prod too hard or you might get an undesirable reaction.) The only person "in charge" here is me, and my only function is to maintain the minimal order necessary to prevent the organism from disintegrating. You as list members may bring up any subject you wish, so long as it relates in a substantive way to the pre-agricultral lifestyle pattern for humans. Indeed, you are encouraged to do so at any time, so long as it relates in a substantive and informed manner. I hope this clears up any private misapprehensions. Please continue. :-)
