Neither of these descriptions goes far beneath the surface. In individual development, as we have said, the main accent falls on the egoistic trend, the striving for happiness; while the other tendency, which may be called the ‘cultural’ one, usually contents itself with instituting restrictions. But things are different in the development of culture: here far the most important aim is that of creating a single unity out of individual men and women, while the objective of happiness, though still present, is pushed into the background; it almost seems as if humanity could be most successfully united into one great whole if there were no need to trouble about the happiness of individuals. The process of development in individuals must therefore be admitted to have its special features which are not repeated in the cultural evolution of humanity; the two processes only necessarily coincide in so far as the first also includes the aim of incorporation into the community. Just as a planet circles round its central body while at the same time rotating on its own axis, so the individual man takes his part in the course of humanity’s development as he goes on his way through life. But to our dull eyes the play of forces in the heavens seems set fast in a never-varying scheme, though in organic life we can still see how the forces contend with one another and the results of the conflict change from day to day. So in every individual the two trends, one towards personal happiness and the other towards unity with the rest of humanity, must contend with each other; so must the two processes of individual and of cultural development oppose each other and dispute the ground against each other. This struggle between individual and society, however, is not derived from the antagonism of the primal instincts, Eros and Death, which are probably irreconcilable; it is a dissension in the camp of the libido itself, comparable to the contest between the ego and its objects for a share of the libido; and it does eventually admit of a solution in the individual, as we may hope it will also do in the future of civilization—however greatly it may oppress the lives of individuals at the present time.
