This book is very well written for the layman, dealing with complex ideas and issues. It is controversial and the points are well made and argued. Using many other sources, Kohn makes a good case for the way he believes we think. The book fits in well with current behavioural psychology, sociology and anthrolopology and reclaims many of the ideas that have been fallen into disfavour. I found this book fascinating to read, although I did not agree with all of the premises. I also do not think that Kohn goes far enough in his interpretation and analysis of some of the data. That said, the style of writing encourages and makes for lively debate!
