�Without the employment of critical thinking by our most famous inventors, scientists, artists, writers, and engineers, most of the achievements that have made human life better for the most part since the Middle Ages would not have occurred. When cultures reject critical thinking, they eventually sink below the intellectual horizon. This book is a remedy for that rejection. So, is this book important and necessary to read? The answer is a resounding yes!� �from the foreword by Jordan Grafman, Ph.D., director of Brain Injury Research and professor, Department of Psychology, Northwestern University
