111:6 Christian Science is natural, but not physical. The Science of God and man is no more supernatural than is the science of numbers, though departing 111:9 from the realm of the physical, as the Science of God, Spirit, must, some may deny its right to the name of Science. The Principle of divine metaphysics 111:12 is God; the practice of divine metaphysics is the utiliza- tion of the power of Truth over error; its rules demon- strate its Science. Divine metaphysics reverses perverted 111:15 and physical hypotheses as to Deity, even as the ex- planation of optics rejects the incidental or inverted image and shows what this inverted image is meant to 111:18 represent. Pertinent proposal A prize of one hundred pounds, offered in Oxford Uni- versity, England, for the best essay on Natural Science, 111:21 - an essay calculated to offset the tendency of the age to attribute physical effects to physical causes rather than to a final spiritual cause, - is one of 111:24 many incidents which show that Christian Science meets a yearning of the human race for spirituality. Confirmatory tests After a lengthy examination of my discovery and its 111:27 demonstration in healing the sick, this fact became evi- dent to me, - that Mind governs the body, not partially but wholly. I submitted my 111:30 metaphysical system of treating disease to the broad- est practical tests. Since then this system has gradually gained ground, and has proved itself, whenever scien- 112:1 tifically employed, to be the most effective curative agent in medical practice. One school of Truth 112:3 Is there more than one school of Christian Science? Christian Science is demonstrable. There can, there- fore, be but one method in its teaching. Those who de- 112:6 part from this method forfeit their claims to belong to its school, and they become adher- ents of the Socratic, the Platonic, the Spencerian, or some 112:9 other school. By this is meant that they adopt and ad- here to some particular system of human opinions. Al- though these opinions may have occasional gleams of 112:12 divinity, borrowed from that truly divine Science which eschews man-made systems, they nevertheless remain wholly human in their origin and tendency and are not 112:15 scientifically Christian.
