There are many books which give some help to many people. There are books which give a set of rules, or even one master rule, by which to meet the problems of life. This is not such a book. It suggests no simple recipe for the conquest of fear. Instead, it presents, what all too few of us to-day possess, a philosophy of life.
Moreover, in contrast to the dominant thinking of our age, which is materialistic, King's philosophy is spiritual and religious. Indeed, the ideas in this book are so profoundly different from the commonly accepted ideas of our times that they will come as a shock to many readers. One purpose of this introduction is to prepare the reader for such a shock.
