Finally, what they need is not physiology alone, but physiology and faith together. There has been a great deal too much science talked about adolescence. Too much physiology, pathology, psychology――not that psychology really is a science――too much analysis, too many statistics. If any of you, as parents or as teachers, do require a short science-book, there is Dr. Starr’s _The Adolescent Period_. It has its faults. It is unduly apprehensive of some things which are not important. It makes too much of those boys and girls who are abnormal. Some children are abnormal; and some, but very few, are as it were demoniac, to their own misery and the misery of others. These most unhappy children have been put under the microscope for us by our kind friends the psychologists. But the vast majority of boys and girls are normal. Dr. Starr’s book is not for general reading. Still, for the right sort of readers, it is a good and useful book. But what, after all, do we want with books? It is the children that we have got to read; not books about them, but them. I doubt whether psychologists understand ordinary children better than a wise old family nurse understands them. Boys and girls are human beings: they were not discovered by science: they refuse to be elucidated by science. The way for us to help them is not by psychology, but by faith, self-preparation, courage, and common sense. _Printed in England by_ Butler and Tanner, _Frome and London_ Transcriber’s Notes: ――Text in italics is enclosed by underscores (_italics_). ――Punctuation and spelling inaccuracies were silently corrected. ――Archaic and variable spelling has been preserved.
