Dr. Schofield says: "That life involves mind has, of course, like all else, been vigorously disputed and equally vigorously affirmed. 'Life,' says Prof. Bascom, 'is not force; it is combining power. _It is the product and presence of mind._' ... The extent to which the word mind may be employed as the inherent cause of purposive movements in organisms is a very difficult question to solve. There can be no doubt that the actual agents in such movements are the natural forces, but behind these the directing and starting power seems to be psychic.... There being an indwelling power, not only for purposive action in each cell, but for endless combinations of cell activities for common ends not at all connected with the mere nutrition of the single cell, but for the good of the completed organism." Dr. R. Dunn says: "From the first movement when the primordial cell-germ of a human organism comes into being, the entire individual is present, fitted for human destiny. From the same moment, matter, life and mind are never for an instant separated, their union constituting the essential work of our present existence." Carpenter says: "The convertibility of physical forces and correlation of these with the vital and the intricacy of that nexus between mental and bodily activity which cannot be analyzed, all lead upwards towards one and the same conclusion--_the source of all power is mind_. And that physical conclusion is the apex of the pyramid which has its foundation in the primitive instincts of humanity." Having seen the evidences of life and mind in the single cell, let us now proceed to a consideration of the intelligence or mind inherent and manifest in the groups of cells, large and small, including the largest groups which compose the several organs of the body. This line of investigation will lead us to a fuller understanding of the influence of the mental states upon the health or disease of the organs and parts. It will be seen that Mental Healing has a sound biological as well as a psychological basis of truth, and that it is not necessary to invade the fields of metaphysics or theology in order to find an explanation of the effect of mind over body.
