At 80 years of age and surrounded by the woes of the world, I must tell the author Ruy Teixeira I NEEDED THIS BOOK. He carefully outlines the last 100 years and brings together the information I needed to see the sweep of the global struggles and successes. He painted the big picture and reveals that the arc of history is bending toward a more evolved world. I keep a record of all the books I read and they are listed by the author last name. Today when I added this book to that list it came right after Teilhard de Chardin. I see this as an affirmation of Teilhard’s vision. If you need an antidote to the daily news this book is for you.
