Observation of the effect of certain accidents and diseases intimates that man forms no exception but that the same results would probably be obtained from similar experiments with him. Though such experiments are out of the question, we can, however, in many different ways ascertain that the soul of man is also inactive in the vegetative functions of his organism. In earliest childhood this is perfectly evident. To possess a soul that has no functions is, as far as the result is concerned, identical with possessing no soul. If we observe a child during the very earliest period of its life we will find that it behaves essentially just as the animals referred to above. Even the child remains in the position it is given and is unable to comprehend what happens around him. The child would likewise starve to death unless food were brought to his mouth, but he swallows and digests the nourishment normally. The movements of the heart, the circulation of the blood and respiration all take place as normally as with the fully developed man during sleep when his soul also ceases to function. The fact that the vegetative processes of the organism are not governed and controlled by the soul may be observed by anyone also during his conscious state. In regard to respiration we may repress it only for a few minutes. A command is soon given by certain cells in the central nerve-system which _against_ the soul’s will brings the organ in question into action. Experience tells us that strong agitations generally disturb the vegetative processes. Sudden fear, for instance, accelerates the heart’s motion. Therefore these processes take place more evenly with animals deprived of their brain just because disturbing influences from the soul are then impossible. Thus it is certain beyond doubt that the cells not only execute but regulate and control through the central nerve-system a multitude of functions in which the soul does not take part. But just as certain it is that there are many functions which the cells could not perform without the co-operation of the soul. Vision, hearing, smelling, tasting and feeling would be entirely meaningless to the cells without the aid of the soul. The same is the case in a high degree with the motions of the body which also require such a higher guidance. The dove could fly, the dog walk, and so forth, but the motions were relatively purposeless. The predetermined plan was lacking. The cells could assimilate the food, when brought into the body, but they could not search it in nature. Such action requires a power of combination that exceeds their measure of intelligence.
