A flood of light has been thrown upon the psychology of paternity by Malinowski's books on the Trobriand Islanders. Three books especially - Sex and Repression in Savage Society, The Father in Primitive Psychology, and The Sexual Life of Savages in North-West Melanesia- are quite indispensable to any understanding of the complex sentiment which we call that of paternity. There are, in fact, two entirely distinct reasons which may lead a man to be interested in a child: he may be interested in the child because he believes it to be his child, or again he may be interested in it because he knows it to be his wife's child. The second of these motives alone operates where the part of the father in generation is not known.
