Yet there is a consideration generally applicable to savage life that must not be overlooked here. Vague, uncertain, and contradictory as the savage may be in his beliefs, sluggish as his mind may be in regard to matters of speculation,--in matters of practical importance, the provision of food and shelter, the protection of his women and children, and the defence of his little community against aggression by human foes or the wild beasts, he is bound to be on the alert and to act. His wits are therefore sharpened for action. Action is natural to him; thought which has no immediate objective in action is strange. The energies remaining when the body is satisfied with food, when shelter is assured, and hostilities against his fellow-man or the lower animals are for the moment forgotten, must be expended in other kinds of action. Bodily recreation--play--satisfies this craving for movement and excitement, while at the same time it fulfils the useful purpose (albeit unconsciously to him) of keeping his faculties, bodily and mental, ready and supple, and of training them still further for more directly practical ends. This form of activity, organized into dances and games, easily begets ritual. The Hottentots danced all night at full moon with extravagant gestures, saluting the moon and invoking her for cattle-fodder and milk.[115.1] The Wichita of {116} North America played every year in the spring a game of shinny, which represented, there can be little doubt, the contest of winter and spring.[116.1] In such cases as these, and they are legion, a recreation has been indulged in at a period appropriate for it--the dance in the clear, cool night, the game under the mild returning warmth and stimulating influences of the early spring. Because it thus naturally recurs at definite times it comes to be regarded as proper, even necessary: it develops into a rite. To a similar game played by the Omaha was attached, in the phrase of the writers who describe it, “a cosmic significance.”[116.2] The impulse to movement, to exertion, liberates emotion; the emotion is in turn intensified by its collective expression; and this intensification would lead to the conviction that the expression has somehow or other in itself an influence on external nature, just as it would have in human relations. The exact mechanism by which it acted probably would not trouble the savage at an early stage. Later, it would be fitted into the framework of his ideas. The Hottentot rite came to be addressed to the moon. The Wichita rite seems to have been thought to assist directly in conquest of the evil power of winter and the renewal of life.
