Note 9 — The Family Law
Reading edition
The Ifugao has the remnant of a peculiar belief that a child may be begotten by two fathers. They say, for example, that if A and B, two men, are having sexual intercourse with a woman, Z, and that if it is settled by fate that A and B each shall beget a child of the male sex, Z will conceive and the child may be the son of both of them. But if A is fated to beget a female child, and B to beget a male child, the semen of the one undoes that of the other, and the woman does not conceive. This belief is not taken seriously as a rule; but I have heard it advanced in a case of illegitimate birth.9
