What are we to think of the miraculous cures reported in Christian Science "experience meetings" and in the columns of the Christian Science journals? Are we to consider them as genuine and accurate records of fact, or are we to reject them as fabrications? It would be easy to deal with the subject by driving Christian Scientists into a corner and logically refuting their claims; for if it is true, as stated on page 120 of "Science and Health," that "health is not a condition of matter but of mind, _nor can the material senses bear reliable testimony on this subject_," of course "the material senses" cannot be trusted when they testify that cancer, consumption, broken bones, or locomotor ataxia have been cured by Christian Science. There is no such thing as the diagnosis of these diseases without reliance on the testimony of "the material senses." But although it is easy thus to refute the Christian Scientists, such refutation satisfies no one and proves nothing except their logical bankruptcy. The victory over their weak-kneed theory is a barren one, for is it not notorious that people's practice may be better than their theory? Skill in logic and in the accurate statement of one's principles may be very slight, and yet the successful application of these misstated or absurd principles may be a fact and a blessing. I shall therefore undertake to examine and to discuss Christian Science cures, not from the point of view of logic or consistency, but by a study of the written testimonials and of my own experience gained in the attempt to verify the claims of those who pronounce themselves cured. Some years ago I followed up, so far as was possible through personal interviews and through letters, all the Christian Science "cures" of which I could hear any details in or near Boston. Within a short time I have returned to the subject and studied one hundred of the cases recorded in the recent volumes of the _Christian Science Journal_ under the caption, "Testimonies from the Field." Putting together this evidence and comparing it with my experience regarding the accuracy of my own patients' statements about their own diseases, past and present, my conclusions are, first, that most Christian Science cures are probably genuine; but, second, that they are not the cures of organic diseases. In my own personal researches into Christian Science "cures," I have never found one in which there was any good evidence that cancer, consumption, or any other organic disease had been arrested or banished. The diagnosis was usually either made by the patient himself or was an interpretation at second or third hand of what a doctor was supposed to have said. As I have followed up the reported cures of "cancer" and other malignant tumors, I have found either that they were not tumors at all, or that they were assumed to be malignant without any microscopic examination. In other words, the diagnosis was never based upon any proper evidence.
