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.
Common sense revolts against the doctrine that pain is a good thing, and the fact of this is everywhere seen in the attempt of man to get rid of it. No one trusts it as a sure warning against disease, no one turns to it as a means of purifying character. All these pleas are the mere platitudes of a religious apologetic trying to harmonise a primitive theory of things with a larger knowledge and a more developed moral sense. Pain and suffering in the world remain facts whether we believe in the existence of a God or not, but we are at least freed from the paralysing horror of the belief that all the suffering and pain in nature is part of a plan. If man realised all that that belief involved it might indeed rob his mind of all strength to struggle against the forces that make for his destruction. Fortunately no race of people could act upon the logical implications of the theistic theory and maintain its existence. In practice, as well as in theory, theism has had to come to terms with facts. And now the series of adjustments have almost reached their end. The belief in God has been traced to its origin, and we know it to have issued in an altogether discredited view of the world and of man. We know that man does not discover God, he invents him, and an invention is properly discarded when a better instrument is forthcoming. To-day the hypothesis of God stands in just the same relation to the better life of to-day as the fire drill of the savage does to the modern method of obtaining a light. The belief in God may continue awhile in virtue of the lack of intelligence of some, of the carelessness of others, and of the conservative character of the mass. But no amount of apologising can make up for the absence of genuine knowledge, nor can the flow of the finest eloquence do aught but clothe in regal raiment the body of a corpse.
