But at last men have reached a state of enlightenment in which they realize that the human body is a machine - none the less a machine because made of flesh instead of iron; that the proper working of the machine is health; its derangement, disease and its stoppage, death. They are able to grasp the great principle that disease means merely that the conditions governing the mechanism have not been met.'
