Once primitive man had made the discovery that it lay in his own hands—speaking literally—to improve his lot on earth by working, it cannot have been a matter of indifference to him whether another man worked with him or against him. The other acquired the value of a fellow-worker, and it was advantageous to live with him. Even earlier, in his ape-like prehistory, man had adopted the habit of forming families: his first helpers were probably the members of his family. One may suppose that the founding of families was in some way connected with the period when the need for genital satisfaction, no longer appearing like an occasional guest who turns up suddenly and then vanishes without letting one hear anything of him for long intervals, had settled down with each man like a permanent lodger. When this happened, the male acquired a motive for keeping the female, or rather, his sexual objects, near him; while the female, who wanted not to be separated from her helpless young, in their interests, too, had to stay by the stronger male.[13] In this primitive family one essential feature of culture is lacking; the will of the father, the head of it, was unfettered. I have endeavoured in _Totem und Tabu_ to show how the way led from this family-life to the succeeding phase of communal existence in the form of a band of brothers. By overpowering the father, the sons had discovered that several men united can be stronger than a single man. The totemic stage of culture is founded upon the restrictions that the band were obliged to impose on one another in order to maintain the new system. These taboos were the first ‘Right’ or law. The life of human beings in common therefore had a twofold foundation, _i.e._ the compulsion to work, created by external necessity, and the power of love, causing the male to wish to keep his sexual object, the female, near him, and the female to keep near her that part of herself which has become detached from her, her child. Eros and Ananke were the parents of human culture, too. The first result of culture was that a larger number of human beings could then live together in common. And since the two great powers were here co-operating together, one might have expected that further cultural evolution would have proceeded smoothly towards ever greater mastery over the external world, as well as towards greater extension in the numbers of men sharing the life in common. Nor is it easy to understand how this culture can be felt as anything but satisfying by those who partake of it.
