allowed none to others.  The
     mind, he declared, adapted, consciously or unconsciously; it did not
     create.  In a letter which follows he elucidates this doctrine.  The
     reference in it to the "captain" and to the kerosene, as the reader
     may remember, have to do with Captain "Hurricane" Jones and his
     theory of the miracles of "Isaac and of the prophets of Baal," as
     expounded in Some Rambling Notes of an Idle Excursion.

     By a trick of memory Clemens gives The Little Duke as his suggestion
     for The Prince and the Pauper; he should have written The Prince and
     the Page, by the same author.

To Rev. F. Y. Christ, in New York:

DEAR SIR,—You say "I often owe my best sermons to a suggestion received in reading or from other exterior sources." Your remark is not quite in accordance with the facts. We must change it to—"I owe all my thoughts, sermons and ideas to suggestions received from sources outside of myself." The simplified English of this proposition is—"No man's brains ever originated an idea." It is an astonishing thing that after all these ages the world goes on thinking the human brain machinery can originate a thought.

It can't. It never has done it. In all cases, little and big, the thought is born of a suggestion; and in all cases the suggestions come to the brain from the outside. The brain never acts except from exterior impulse.

A man can satisfy himself of the truth of this by a single process,—let him examine every idea that occurs to him in an hour; a day; in a week—in a lifetime if he please. He will always find that an outside something suggested the thought, something which he saw with his eyes or heard with his ears or perceived by his touch—not necessarily to-day, nor yesterday, nor last year, nor twenty years ago, but sometime or other. Usually the source of the suggestion is immediately traceable, but sometimes it isn't.

However, if you will examine every thought that occurs to you for the next two days, you will find that in at least nine cases out of ten you can put your finger on the outside suggestion—And that ought to convince you that No. 10 had that source too, although you cannot at present hunt it down and find it.

The idea of writing to me would have had to wait a long time if it waited until your brain originated it. It was born of an outside suggestion—Sir Thomas and my old Captain.

The hypnotist thinks he has invented a new thing—suggestion. This is very sad. I don't know where my captain got his kerosene idea. (It was forty-one years ago, and he is long ago dead.) But I know that it didn't originate in his head, but it was born from a suggestion from the outside.

Yesterday a guest said, "How did you come to think of writing 'The Prince and the Pauper?'" I didn't. The thought came to me from the outside—suggested by that pleasant and picturesque little history-book, Charlotte M. Yonge's "Little Duke," I doubt if Mrs. Burnett knows whence came to her the suggestion to write "Little Lord Fauntleroy," but I know; it came to her from reading "The Prince and the Pauper." In all my life I have never originated an idea, and neither has she, nor anybody else.

Man's mind is a clever machine, and can work up materials into ingenious fancies and ideas, but it can't create the material; none but the gods can do that. In Sweden I saw a vast machine receive a block of wood, and turn it into marketable matches in two minutes. It could do everything but make the wood. That is the kind of machine the human mind is. Maybe this is not a large compliment, but it is all I can afford.....
