Another form of the same argument meets us in the familiar plea that bodily pain "sounds the alarm bell of disease in time for its removal." In some sense it may be admitted that a painful feeling, in certain circumstances, does act as a warning that persistence will lead to disaster. But it is not universally true in the sense and in the degree that is needed to justify the argument, and it is a "warning" out of all proportion to the danger faced. In the first place, pain cannot be a warning against disease, it can only be an indication of its presence. It does not warn us against the dangers of a contemplated course of conduct, nor can it tell us what conduct has led to the pain experienced. And in the case of contagious diseases, what amount of warning is there given? In some case the victim is stricken and is dead in so short a time as not to know with what it is he has been afflicted, and certainly without any chance of being warned. What warning is there in the case of a violent poison? Or what relation is there between pains felt and dangers run? The most dangerous diseases may have painless beginnings, and be well rooted in the system before the victim is driven by discomfort to seek medical advice. On the other hand, a corn or a toothache, neither of them very deadly ailments, create pain out of all proportion to their gravity. And if we take the case of excessive cold we have here an instance where instead of pain acting as a warning, the danger just acts as an anaesthetic. The victim is oppressed by drowsiness, sinks into insensibility, finally death. Here it is not the approach of death that is painful, but the return to life, the pain of restoring circulation being very severe indeed. Fear, which may be classed as a species of pain, appears to act, in the majority of instances, as an enemy, rather than as a friend to the animal experiencing it. Thus Professor Mosso points out that in the animal organism there exists a number of harmful reactions that increase in number the graver the peril becomes. We have all read of the "fascination" of the bird by the serpent, and there are other animals that in the presence of an enemy become so palsied with fear as to become incapable of defence, even that of flight. And with man it is not as the danger becomes most acute that his nerves become steadier and his courage firmer. The opposite is probably more often the case. In all these cases it is as though nature had lured the animal or man into a position of grave danger, and then does its best to divest him of adequate means of defence against it.
