An Introduction to General Systems Thinking might be interested in my answers to his questions:
Reader: I'm interested in learning more about the "Law of Medium Numbers" described in your book of An Introduction to General Systems Thinking. I feel the "Law of Medium Numbers" sheds light on many puzzles I have run into in dealing with nature and society. Thus I wonder whether I may ask you a few related questions? -
1. As I searched the literature trying to learn more about this subject and the "Law of Medium Numbers", I was surprised by how little I could find. I wonder whether I was not doing right searches or you may have more insights into this?
Jerry: It's not a popular subject with many scientists, because it shows how science—though amazingly successful in some areas—it's awfully limited in dealing with some of the most interesting problems. As someone pointed out years ago, "Physics is merely the study of those systems for which the methods of physics work."
Reader: 2. I wonder whether the "Law of Medium Numbers" might imply a kind of defiance of classical Western science and technology (which emphasize certainty and perfection)?
Jerry: That's well put. We'd like things to be different, but they aren't.
Reader: 3. Perhaps human individuals are medium number systems and thus may explain why we all have certain limitations (in other words, no one is perfect). So medium number systems may also be called imperfect systems. Am I right on this?
Perfect Software and Other Illusions about Testing. It's extremely popular among software testers. They use it to explain to their customers what amounts to the Law of Medium Numbers applied to software. And, a few software developers have shown violent reactions to the claim that perfection is simply not possible.
