Said a friend of mine to me some months ago: “Well now, why don’t you write a sensible book? I should like to see you make people think.”

“Do you believe it can be done, then?” I asked.

“Well, try,” he replied.

Accordingly, I have tried. This is a sensible book. I want you to understand that. This is a book to improve your mind. In this book I tell you all about Germany—at all events, all I know about Germany—and the Ober-Ammergau Passion Play. I also tell you about other things. I do not tell you all I know about all these other things, because I do not want to swamp you with knowledge. I wish to lead you gradually. When you have learnt this book, you can come again, and I will tell you some more. I should only be defeating my own object did I, by making you think too much at first, give you a perhaps, lasting dislike to the exercise. I have purposely put the matter in a light and attractive form, so that I may secure the attention of the young and the frivolous. I do not want them to notice, as they go on, that they are being instructed; and I have, therefore, endeavoured to disguise from them, so far as is practicable, that this is either an exceptionally clever or an exceptionally useful work. I want to do them good without their knowing it. I want to do you all good—to improve your minds and to make you think, if I can.

What you will think after you have read the book, I do not want to know; indeed, I would rather not know. It will be sufficient reward for me to feel that I have done my duty, and to receive a percentage on the gross sales.
