To return to the question of jealousy, we have, after having stated the general problems, discussed the influence exercised on it by social pressure or custom and other psychical factors. Finally we have shown that the sexual act is not in all tribes conceived as leading to childbirth, and that this bears upon the problem of jealousy. But it must be remembered that they have ideas of the sexual act which are entirely foreign to us, and which may account also for some differences in their views of, and feelings about, jealousy. Here come in ideas of the magic influences and virtues attributed to the sexual act. In Australia there are unmistakable signs of it. The ceremonial act of defloration, in connection with the initiation of females, is undoubtedly connected with some mystic ideas of its magical character. This is shown especially clearly in the fact that this ceremonial act is employed for medicinal or hygienic purposes, as stated in Roth and in Beveridge.[351] We saw that the only instance of the exchange of wives in the Kurnai tribe was when it was ordered by the old men, to avert impending evil. The same is reported by Cameron of some of the Darling River tribes. This shows clearly how feelings of jealousy, which seem to have been fairly strong in this tribe, may be subservient to a belief in the magical, beneficial influence of sexual intercourse, performed in a certain prescribed way. The many instances in which sexual intercourse, usually not between husband and wife, takes place during certain religious ceremonies, as well as the fact of sexual abstinence, which is often to be observed on such occasions, shows that it has its magical side. From this conception of the sexual act as endowed with some magic properties, there would result differences in the ideas and feelings connected with jealousy. On the one hand, such magic properties would require in some cases the waiving of individual sexual rights, as we saw in some of the instances just mentioned. And in these cases the instincts of jealousy would be suppressed by the more powerful feelings inspired by supernatural apprehensions. On the other hand, it is possible--although there are no examples of it--that the very magical aspect of the sexual act would make it especially subject to jealous watchfulness and exclusiveness. Apart from any speculations, it appears certain that all these different ideas and conceptions are in intimate interdependence, and that we can only safely speak about jealousy (or any other such compounded psychical complex) in a given society, when we know all such connections.[352] [351] Roth, _Ethnol. Stud._, p. 174. Beveridge, p. 53, Latin note. [352] The idea of a radical difference in the psychological aspect of jealousy among lower races of men is set forth by Dr. Westermarck: "Jealousy ... is far from being the same feeling in the mind of a savage as in that of a civilized man."--_H.H.M._, p. 30.
