The deductions of her philosophy are often characterised by an astonishing naivete. "God being All-in-all, He made medicine," she tells us; "but that medicine was Mind. . . . It is plain that God does not employ drugs or hygiene, nor provide them for human use; else Jesus would have recommended and employed them in His healing." She frequently makes use of ingenious statements whose very candour is disarming, but she had considerable dialectical gifts, and can argue persuasively, especially against spiritualism. In _Science and Health_ she violently denies the authenticity of spiritualistic phenomena, "As readily can you mingle fire and frost as spirit and matter. . . . The belief that material bodies return to dust, hereafter to rise up as spiritual bodies with material sensations and desires, is incorrect. . . . The caterpillar, transformed into a beautiful insect, is no longer a worm, nor does the insect return to fraternise with or control the worm. . . . There is no bridge across the gulf which divides two such opposite conditions as the spiritual, or incorporeal, and the physical, or corporeal." In the confusion of precepts and principles championed by Mrs. Eddy there are sometimes to be found thoughts worthy of a great metaphysician. Her teaching, when purified from admixture, does at any rate break away energetically from all materialistic doctrines. Her literary output was considerable, for in addition to her gospel, _Science and Health_, she wrote _The Concordance of Science and Health_, _Rudimentary Divine Science_, _Christian Science versus Paganism_, and other works, including some verse. The Christian Science churches, with their adherents, who number more than a million, are spread all over the world, each having an independent existence. They are found chiefly in the United States, England, Germany, and the British Colonies. The number of "healers" exceeds several thousands, for the most part of the female sex. In France the first "Church of Christ, Scientist" has been founded in Paris, in the Rue Magellan, under the name of Washington Palace. The Christian Science leader denounced the established churches and spared them no criticism, and her doctrine contained a seed of truth which enabled it to triumph even over its own lack of logic and coherence. The world, submerged in matter, either denies spirit or turns away from it. Mrs. Eddy exalts the power of spirit above that of matter, the universal goddess, by means of statements which are heroic rather than scientific.
