(_f_) Most of the amusements as well as the occupations of mankind depend for their zest upon the spirit of hunting and fighting, which they gratify and relieve, either directly or in a conventionalised and symbolical way, and at the same time keep alive. Sports and games involve the pursuit of some end by skill and strategy, often the seizing upon some sort of prey, or slaying outright, and they give scope to emulation. Emulation is a motive in the race for wealth, in every honourable career, even in addiction to science and learning: though here the main stress is upon an instinct older than the pack—curiosity, a general character of the Primates. That children at first play alone, later play together, and then “make up sides,” repeats the change from the comparatively solitary life of anthropoids to the social life and combined activities of the hunting-pack. From the interest of the chase and the aggressiveness that is involved in it must be derived all that we call “enterprise,” whether beneficent or injurious: a trait, certainly, which there is little reason to regard as inherited from the anthropoid stock. (_g_) The great amusement and pastime of feeding has, no doubt, descended to us in unbroken tradition, through harvest and vintage festivals, from the unbridled indulgence that followed a successful hunt. And I offer the conjecture that the origin of laughter and the enjoyment of broad humour (so often discussed) may be traced to these occasions of riotous exhilaration and licence. We may suppose, indeed, that these conditions began to prevail not in the earliest days of the ravenous pack, but after some advance had been made in the customs of eating. Savages usually cram to repletion when possible, and with huge gusto, for there may not soon be another opportunity. If uproarious feasting was advantageous physically and socially (as till recently we all thought it was), addiction to the practice was a ground of survival; and laughter (a discharge of undirected energy, as Spencer says), being its natural expression and enhancement, shared in its perpetuation. This social origin agrees with the infectiousness of laughter, with its connection with triumph and cruelty, and with the quality of the jokes that still throughout the world excite most merriment—practical jokes and allusions to drunkenness, the indecorous, the obscene. Sir Robert Walpole preferred such humour as the most sociable; because in that everybody could take part. Many refinements have been introduced in polite circles; but it is in vain that one begins a theory of laughter with an analysis of the genius of Molière. Similarly, I suppose that weeping, lamentation and the facial and bodily expressions of grief were developed by the social utility of common mourning in tribal defeat and bereavement. § 7.
