There is also a chemico-vital, kinetic, or magnetic body, diffused through and inter-penetrating all the rest. This gives the contrast between the living organism (with the flush of health upon the cheek and the light of intelligence in the eyes), and a corpse. Death is often instantaneous, while decomposition often waits for days. There is a still further analogy regarding a single function, like a sensory or motor impulse, passing to or from the central brain, the organ of consciousness. The journey is one of relays and orderly sequences. This is proven in a great variety of forms of paresis. I cannot, as an individual intelligence, _directly_ move my hand any more than I can move a mountain. I conceive the object or act and set the will in motion. The impulse traverses the nerves, is transferred to the muscle, and then, when the circuit is complete, _I_ move my hand. The gap between my conscious intelligent wish and will, and my physical hand, is very great. One is metaphysical, the other physical. There is, therefore, a point of correlation where the one is converted into the other. The knowledge of these facts, and of this orderly sequence and correlation, constitutes the Science of pathology and enables us to locate the lesion or disease. I cannot move my hand, and the pathologist locates the "short-circuit" in brain, or nerve, or "terminal plate," or muscle, as the case may be. Now it is this _system_ of _composite systems_ that deserves special attention. We know that it exists as a series of relays and refining processes. In disease it is interrupted, or out of joint, or broken down. Health means harmony, concord, rhythm between every part, and the power of the one individual intelligence to use it all, to act or refrain from action, and to hold and maintain through all, repose, equilibrium, and self-mastery. The physical body we know to be a thing of sense and time. We know its beginning, its gestation, its entrance and exit on this material plane. Its secrets are all involved in the subtle relations it bears to the soul that inhabits, unifies, and utilizes it. The Individual Intelligence, Ego, Soul, or Entity, is as patent to us in our _awareness of self_ as is the body it inhabits. It is our _very self_. Our knowledge of it is a _direct personal experience_, so direct, immediate, and constant that we overlook its significance. I can see no reason to imagine that a human being, passing from the earthly plane and consciously living on the spiritual plane and recognizing itself as the same individual, would be any wiser as to the exact nature and origin of the Individual Intelligence than he is now; though his field of vision and range of conscious experience had so immeasurably increased and expanded. If he had solved this problem of _ultimates_, he would be at the end of his thread of life and would compass the Infinite. He would be no longer Man, but God.
