Christian Science, then, is not monism, it is rather a dualism; it confronts not one but two ranges of reality and it is compelled to admit the existence of the reality which it denies, even the fact of denying it, for it is a philosophical axiom that what we deny exists for us--we could not otherwise deny it. Denial is the recognition of reality just as much as affirmation. To repeat, it is this continuous interwoven process of trying to reconcile the one-sided idealism of Christian Science with the necessity of its argument and the facts of life which gives to "Science and Health" what one may call its strangely bifocal character, though indeed this is a somewhat misleading figure. One has the same experience in reading the book that one has in trying to read through glasses which are out of focus; you are always just seeing and just missing because Mrs. Eddy herself is always just seeing and just missing a really great truth. This fundamental inconsistency penetrates the whole system even down to its practical applications. Christian Science denies the testimony of the senses as to sickness and yet accepts them as to health. It goes further than this, it accepts the testimony of the senses of other people--physicians, for example, in accepting their diagnosis. The edition of "Science and Health" published in 1918 offers in chapter eighteen a hundred pages of testimonials sent in by those who have in various ways been helped by their faith. These letters are shot through and through with a recognition of the testimony of the senses which no explanation can possibly explain away. "I was afflicted with a fibroid tumour which weighed not less than fifty pounds, attended by a continuous hemorrhage for eleven years." If the senses have any language at all, this is their language. A growth cannot be known as a fibroid tumour without sense testimony, nor its weight estimated without sense testimony, nor a continuous hemorrhage be recorded, or its cessation known without sense testimony, nor can epilepsy be diagnosed, nor bilious attacks recognized without sense testimony. On page 606 a grateful disciple bears witness to the healing of a broken arm, testimony to said healing being demonstrated by a visit to a physician's office "where they were experimenting with an X-ray machine. The doctor pointed out the place as being slightly thicker at that part, like a piece of steel that had been welded." In other words, Christian Science cannot make out its case without the recognition of the veracity of a sense testimony, whose truth its philosophy denies.
