The real significance of this much debated but otherwise unimportant episode is that it seems to have thrown Mrs. Eddy upon her own resources, for now that Quimby was dead she begins to develop what she had received from him through both experience and teaching along lines of her own. She had found a formula for the resolution of problems, both physical and mental, which had hag-ridden her for years. She had a natural mental keenness, a speculative mind, a practical shrewdness (the gift of her New England ancestors) and an ample field. The theology, the medical science and indeed the philosophy or psychology of the New England of the sixties contributed strongly, through their limitations, to the growth of bizarre systems which had in them elements of truth. We shall need to come back to this again in any evaluation of Christian Science as a whole, but we cannot understand the rapid development of the movement of which Christian Science was just one aspect without taking all this into consideration. Medicine itself has been greatly revolutionized within the last fifty years. While Mary Baker Glover Patterson Eddy was finding her unhappy way through border-land regions into a cloudy light, Louis Pasteur, sitting, in the phrase of Huxley, "as humbly as a little child before the facts of life," was making those investigations in bacteriology which were to be, in some ways, the greatest contribution of the nineteenth century to the well-being of humanity. He was following patiently the action of microscopic organisms, especially in their relation to health, discovering the secret of contagion and infection, outlining methods of defense against the attacks of these invisible armies, finding the true basis for inoculation, extending its operation, robbing hospitals of their terrors and surrounding surgery with safeguards heretofore undreamt of, literally performing miracles (in his control of swine plague and the like), and for the want of another subject preparing to experiment upon himself for the prevention of hydrophobia, and in doing it all in the most simple and humble way, naively unconscious of his own fame and living from first to last in a noble and comparative poverty which contrasts dramatically with the material well-being for which Mrs. Eddy was so eager. Nothing of this had ever come into Mrs. Eddy's field or those whom she addressed. With all the aid which the modern physician has at his control, diagnosis is still a difficult matter, physicians confess it themselves. There is still, with all the resource of modern medical science, a residuum of hopeless and obscure cases which baffle the physician. That residuum was very much larger fifty years ago than it is now. _She Begins to Teach and to Heal_
