This is the other side of the fair shield of religious faith. Why, if there be a power which loves and can be persuaded to aid us, may there not also be a power which hates, and can be persuaded to destroy? No religion has ever been able to answer this, and therefore none has ever been able to escape from devil-terrors. Even Jesus was pursued by Satan, and the Holy Catholic Church has its ceremonies for the exorcising of demons, and a most frightful formula for cursing. And here are our friends the Christian Scientists, proclaiming the unreality of all evil, their ability to banish disease by convincing themselves that they are perfect in God--yet tormented by a squalid phobia called "Mental Malpractice", or "Malicious Animal Magnetism". Christian Science is the most characteristic of American religious contributions. Just as Billy Sunday is the price we pay for failing to educate our base-ball players, so Mary Baker Glover Patterson Eddy is the price we pay for failing to educate our farmer's daughters. That she had a power to cure disease I do not doubt, because I have a little of it myself. At first my opinion was that her "Science" made its way by curing the imaginary ailments of the idle rich. If a person has nothing to do but think that he is sick, you can work easy miracles by persuading him to think that he is well; and if he has nothing to do but think that he is well, he will help you to build marble churches and maintain propaganda societies. But recently I have experimented with mental healing--enough to satisfy myself that the subconscious mind which controls our physical functions can be powerfully influenced by the will.
