Suppose next the case of a man who is thrown out of correspondence with a part of his environment by some physical infirmity. Let it be that by disease or accident he has been deprived of the use of his ears. The deaf man, in virtue of this imperfection, is thrown out of _rapport_ with a large and well-defined part of the environment, namely, its sounds. With regard to that "external relation," therefore, he is no longer living. Part of him may truly be held to be insensible or "Dead." A man who is also blind is thrown out of correspondence with another large part of his environment. The beauty of sea and sky, the forms of cloud and mountain, the features and gestures of friends, are to him as if they were not. They are there, solid and real, but not to him; he is still further "Dead." Next, let it be conceived, the subtle finger of cerebral disease lays hold of him. His whole brain is affected, and the sensory nerves, the medium of communication with the environment, cease altogether to acquaint him with what is doing in the outside world. The outside world is still there, but not to him; he is still further "Dead." And so the death of parts goes on. He becomes less and less alive. "Were the animal frame not the complicated machine we have seen it to be, death might come as a simple and gradual dissolution, the 'sans everything' being the last stage of the successive loss of fundamental powers."[57] But finally some important part of the mere animal framework that remains breaks down. The correlation with the other parts is very intimate, and the stoppage of correspondence with one means an interference with the work of the rest. Something central has snapped, and all are thrown out of work. The lungs refuse to correspond with the air, the heart with the blood. There is now no correspondence whatever with environment--the thing, for it is now a thing, is Dead.
This then is Death; "part of the framework breaks down," "something has snapped"--these phrases by which we describe the phases of death yield their full meaning. They are different ways of saying that "correspondence" has ceased. And the scientific meaning of Death now becomes clearly intelligible. Dying is that breakdown in an organism which throws it out of correspondence with some necessary part of the environment. Death is the result produced, the want of correspondence. We do not say that this is all that is involved. But this is the root idea of Death--Failure to adjust internal relations to external relations, failure to repair the broken inward connection sufficiently to enable it to correspond again with the old surroundings. These preliminary statements may be fitly closed with the words of Mr. Herbert Spencer: "Death by natural decay occurs because in old age the relations between assimilation, oxidation, and genesis of force going on in the organism gradually fall out of correspondence with the relations between oxygen and food and absorption of heat by the environment. Death from disease arises either when the organism is congenitally defective in its power to balance the ordinary external actions by the ordinary internal actions, or when there has taken place some unusual external action to which there was no answering internal action. Death by accident implies some neighboring mechanical changes of which the causes are either unnoticed from inattention, or are so intricate that their results cannot be foreseen, and consequently certain relations in the organism are not adjusted to the relations in the environment."[58]
With the help of these plain biological terms we may now proceed to examine the parallel phenomenon of Death in the spiritual world. The factors with which we have to deal are two in number as before--Organism and Environment. The relation between them may once more be denominated by "correspondence." And the truth to be emphasized resolves itself into this, that Spiritual Death is a want of correspondence between the organism and the spiritual environment.
