If you are under eighteen years old, close this book. It would not interest you.
To those past that age I say: Whatever are your opinions, read it through without shock or start. Then judge calmly and conscientiously my comments on the truths so mysteriously taught me. You will see—provided you have a grain of common sense—that I attack principles, not individuals. I have no desire to hurt quadruped or biped; not even those who have injured me past world-healing.
If you possess any—the smallest amount—of real reverence, you will understand the deeply reverent feeling with which all herein is written.
H. A. Dugdale.
