I thoroughly enjoyed reading this book. Being a student of complexity, I appreciated John Kay's thought provoking and academic discussion. I think the author strikes a balance between lucidly articulating the oblique approach in this book, as well as acknowledging there are more direct approaches to goal achievement that beome available in contained environments.
The author does us a great service by describing the oblique approach well, and reminding us of many of the flaws of the direct approaches. The book is rather well written, succinct and has great ideas in it to consider.
