Chapter III The power of the father Once paternity is recognized as a fact of physiology, in the primary sense of love of man to children there is a completely new element, which leads to the emergence almost everywhere patriarchal society. When a man realizes that the child - in the words of the Bible - is the fruit of his "seed", his feeling of love is doubly enhanced by the fact that he has a feeling of parental authority and the desire to conquer death in the sense that the achievements of his descendants continue his achievements and life is a continuation of his life. The feeling of vanity does not disappear with his life, but is transmitted to descendants indefinitely. Look how happy was Abraham, when he learned that the tribe "the seed" shall possess the land of Canaan. In times of matriarchal family vanity probably seen only in women; but since they do not participate in the war, a desire for the glory of his family have been much weaker than that of men. Apparently, the new father's sense of making society more dynamic and active, has made it an element of competition and struggle, which was not in the matriarchal society. In addition, exposure to some extent hypothetical, was a new and much more important reason, which served as the basis for compliance with the requirements of fidelity to their wives. Note that in the sense of jealousy purely instinctive element is not as significant as we imagine.
