(M169) The jealous protection thus afforded by Australian men and women to bats and owls respectively (for bats and owls seem to be the creatures usually allotted to the two sexes)(583) is not based upon purely selfish considerations. For each man believes that not only his own life but the lives of his father, brothers, sons, and so on are bound up with the lives of particular bats, and that therefore in protecting the bat species he is protecting the lives of all his male relations as well as his own. Similarly, each woman believes that the lives of her mother, sisters, daughters, and so forth, equally with her own, are bound up with the lives of particular owls, and that in guarding the owl species she is guarding the lives of all her female relations besides her own. Now, when men’s lives are thus supposed to be contained in certain animals, it is obvious that the animals can hardly be distinguished from the men, or the men from the animals. If my brother John’s life is in a bat, then, on the one hand, the bat is my brother as well as John; and, on the other hand, John is in a sense a bat, since his life is in a bat. Similarly, if my sister Mary’s life is in an owl, then the owl is my sister and Mary is an owl. This is a natural enough conclusion, and the Australians have not failed to draw it. When the bat is the man’s animal, it is called his brother; and when the owl is the woman’s animal, it is called her sister. And conversely a man addresses a woman as an owl, and she addresses him as a bat.(584) So with the other animals allotted to the sexes respectively in other tribes. For example, among the Kurnai all emu-wrens were “brothers” of the men, and all the men were emu-wrens; all superb warblers were “sisters” of the women, and all the women were superb warblers.(585) § 4.
