This more varied and adventurous existence roused new centres of activity in his brain; he began to perceive, though dimly, the possibilities of a larger life, though doubtless one which would minister to his own comfort rather than to that of his family—the natural and only road to better things. He began to devise more expeditious means of securing food, and circumventing his enemies, among whom the most formidable was his fellow-man, because in him he met his match. In the course of his wanderings he had learned the use of stones as weapons—which he could never have done in the forests—and he had also discovered the value of his family as ministers to his comfort, if only by setting them to collect such food as did not require strength and cunning in its capture. An inherent love of the chase for the sake of the excitement which this afforded probably made him nothing loth to regard hunting as his own peculiar duty. A little later the advantages of neighbourliness were borne in on him, largely for the sake of the greater ease wherewith the animals of the chase could be captured by their combined efforts; but this begat comradeship and some of the graces which follow therefrom. Thus was laid the foundation of Society and “civilization” with all its attendant barbarities. Then, as now, whatever discordant notes were heard, were those struck by the twin Demons Envy and Jealousy. These disturbers of the peace are parasites on Society, their very existence depends on it. They have played a larger part in fashioning its rules and regulations than is generally realized. Their influence is as powerful to-day as ever in the past. It expresses itself in varying degrees in different individuals, and is roused by varying causes. But the most potent of all is jealousy in regard to sexual matters.
