Diseased conditions in the human body are often traceable, by a subtle and penetrating analysis, to diseased conditions in the human soul. Medical science deals chiefly with the physical organism, and so long as it persists in regarding only that part of the being of man, so long will it continue to find its theories falsified, its carefully prepared experiments turned into blind guesses, and its high percentage of failures maintained. I might make my point clearer, perhaps, by stating that the body is after all only a sensitive machine, and that if the thinking and feeling man who uses that machine in self-expression is distorted, unbalanced, or discordant in any way, then these undesirable qualities will reproduce themselves in the physical organism as appropriate disease or functional derangements.
