(M103) If the reader still doubts whether the rules of conduct which we have just been considering are based on superstitious fears or dictated by a rational prudence, his doubts will probably be dissipated when he learns that rules of the same sort are often imposed even more stringently on warriors after the victory has been won and when all fear of the living corporeal foe is at an end. In such cases one motive for the inconvenient restrictions laid on the victors in their hour of triumph is probably a dread of the angry ghosts of the slain; and that the fear of the vengeful ghosts does influence the behaviour of the slayers is often expressly affirmed. The general effect of the taboos laid on sacred chiefs, mourners, women at childbirth, men on the war-path, and so on, is to seclude or isolate the tabooed persons from ordinary society, this effect being attained by a variety of rules, which oblige the men or women to live in separate huts or in the open air, to shun the commerce of the sexes, to avoid the use of vessels employed by others, and so forth. Now the same effect is produced by similar means in the case of victorious warriors, particularly such as have actually shed the blood of their enemies. In the island of Timor, when a warlike expedition has returned in triumph bringing the heads of the vanquished foe, the leader of the expedition is forbidden by religion and custom to return at once to his own house. A special hut is prepared for him, in which he has to reside for two months, undergoing bodily and spiritual purification. During this time he may not go to his wife nor feed himself; the food must be put into his mouth by another person.(564) That these observances are dictated by fear of the ghosts of the slain seems certain; for from another account of the ceremonies performed on the return of a successful head-hunter in the same island we learn that sacrifices are offered on this occasion to appease the soul of the man whose head has been taken; the people think that some misfortune would befall the victor were such offerings omitted. Moreover, a part of the ceremony consists of a dance accompanied by a song, in which the death of the slain man is lamented and his forgiveness is entreated. “Be not angry,” they say, “because your head is here with us; had we been less lucky, our heads might now have been exposed in your village. We have offered the sacrifice to appease you. Your spirit may now rest and leave us at peace. Why were you our enemy? Would it not have been better that we should remain friends? Then your blood would not have been spilt and your head would not have been cut off.”(565) The people of Paloo, in central Celebes, take the heads of their enemies in war and afterwards propitiate the souls of the slain in the temple.(566) In some Dyak tribes men on returning from an expedition in which they have taken human heads are obliged to keep by themselves and abstain from a variety
