Donella Meadows is one of the 20th Century's most well known systems theorists, mostly due to her landmark book Limits to Growth. This follow-on, written in the 90s and published in 2006, is a high-level introduction to systems theory.

As a basic book on a subject, it is accessible and sometimes enjoyable. It is strongeSt when Meadows is exploring comcepts like nonlnear systems, where as a reader you can consider the implications. But the book is not well written, and uses far too many examples, sometimes contradictory ones, without useful evidence or theory. While it is refreshing to see a stance in the 90s that supports systemic change, other more recent books do this better.

Also, the unapologetic references to Garrett Hardin are pretty unpalettable to anyone who knows about him.
