This book explains that the natural and only quite wholesome way of teaching is to let the child's desire for knowledge operate in the schoolboy and guide the teacher. This means that without foregoing discipline, nor cutting ourselves off from tradition, we must continue experiments already being started in our elementary schools. These are based on the chastening fact that children learn best before we adults begin to teach them at all: and hence that however uncongenial the task may be, we must conform our teaching methods to those of Nature. The attempt has often been made before. But in this book there is a rare combination of intuitive insight and practical sagacity. The author refused to believe that the collapse of the desire for knowledge between seven and seventeen years of age is inevitable.
