This book can be only a guide to you. You are to help your students study human nature. You must, to some extent, be a psychologist yourself before you can teach psychology. You must yourself be a close and scientific student of human nature. Develop in the students the spirit of inquiry and investigation. Teach them to look to their own minds and their neighbor's actions for verification of the statements of the text. Let the students solve by observation and experiment the questions and problems raised in the text and the exercises. The exercises should prove to be the most valuable part of the book. The first two chapters are the most difficult but ought to be read before the rest of the book is studied. If you think best, merely read these two chapters with the pupils, and after the book is finished come back to them for careful study.
