Although I only got about two-thirds of the way through this book, I am very glad that I read to the point that I did wear the idea of changeable and moving intelligence is discussed. sewing notion of Intelligence being fixed which never did sound very reasonable in fact is not reasonable. This is good to know for a variety of reasons. I think this is a good book to read for those who worry about the impact of Intelligence on our society and what we can do about it in terms of making a place with dignity for everyone.
