This, frankly is deeply impressive. Thanks The Long Now Foundation for leading me into something that I fear will obsess me for some time! We always think we are so new and original in our thinking and we forget how old the concepts and ideas we are working with actually are. This is a as true in books as it is in techonology of all sorts. If you doubt it, read this book which has much to say on the subject.
Having a spiffy weekend.
