The following letter was written by a Scientist to his brother.
Dear Brother:—It is more than a year since I wrote to you. I also wrote C. a letter on Christian Science, but when she answered it she never mentioned the subject. She sent the letter to S., who got so excited about it that she wanted the mother of the two children who were visiting here to send for them to come home at once, for they would be ruined by attending a Christian Science Sunday School. Of course She, and I suppose you all, think I am crazy. I made up my mind then that I would not write home again until I had such a knowledge of Science as I thought would convince you that I had some sense left.
I suppose you think, as a great many others do who have not studied the subject, that Christian Science is some newfangled theory, such as spiritualism, theosophy, etc. That is not the question. The only question is, is it true? Nothing is true but the absolute Truth. The only way to prove the truth of anything is by demonstration. If I have a theory that I can build a machine to do a certain thing and show you the drawing of it, and your theory is that it cannot be done, your theory may be just as good as mine; now, if I build the machine and it works just as I said it would, that proves my theory as correct and yours as not; then it is no longer a theory, but an actual fact.
