At present, like Dr Myers, I am not convinced; but I have seen enough of Christian Science results among my own friends to prevent me from denying anything. I merely suspend judgment. But I do believe that the power of the mind over the body is so great that almost anything is possible; and I think that the medical advance of the next half-century will be chiefly in this hitherto neglected direction. I happen to know that this, or something very near this, was the strongly-held opinion of the late Professor William James of Harvard, who, in addition to being the most brilliant psychologist of his generation, was also a qualified doctor of medicine. JOAN OF ARC Great results often flow from small causes. Pascal said that if Cleopatra's nose had been shorter the history of the world would have been different. Similarly it may be truly said that if a peasant girl of Domrémy had not had hallucinations, France would now have been a British province. And it is curious to reflect that the Church which burnt her as a heretic and sorcerer has her, and her only, to thank for such hold as it still maintains on France, for the latter would have become Protestant if England had won. The Roman church now recognises this, and has beatified the Maid. The next step will be her canonisation as a saint. Thus does the whirligig of Time bring its revenges. Jeanne d'Arc was born in the village of Domrémy near Vaucouleurs, on the border of Champagne and Lorraine, on January 6th, 1412. She was taught to spin and to sew, but not to read or write, these accomplishments being beyond what was necessary for people in her station of life. Her parents were devout, and she was brought up piously. Her nature was gentle, modest, and religious, but with no physical weakness or morbid abnormality--on the contrary, she was exceptionally strong, as her later history proves. At or about the age of thirteen, Jeanne began to experience what psychology now calls "auditory hallucinations". That is, she heard voices--usually accompanied by a bright light--when no visible person was present. This, of course, is a common symptom of impending mental disorder; but no insanity developed in Jeanne d'Arc. Startled she naturally was at first, but continuation led to familiarity and trust. The voices gave good counsel of a commonplace kind, as, for instance, that she "must be a good girl and go regularly to church." Soon, however, she began to have visions: saw St Michael, St Catherine, and St Margaret; was given instructions as to her mission; eventually made her way to the Dauphin; put herself at the head of 6,000 men, and advanced to the relief of Orleans, which was besieged by the conquering English. After a fortnight of hard fighting the siege was raised, and the enemy driven off. The tide of war had turned, and in three months the Dauphin was crowned King at Rheims, as Charles the Seventh.
