Artificial vs. Natural Science - reading Herbert A. Simon's "The Sciences of the Artificial"

"The Sciences of the Artificial " is an amazing book. The author Simon could combine such a varitey of topics ranging from economics, organization, engineering design and Artificial intelligence into one theme called "Artificial". Of course, it must be much more challenging to establish artificial science than Natural Science, because it is man made, and it is changing for ever. Not like natual science, you progress to further understanding of same phenomena, the Artificial, with human involved, is about generating, which makes it impossible to have a fixed or stable set of principles.
