In the latter case resulting in the hostility towards the culture. Freud here examines what factors make the origin of culture, and what determined its subsequent course. From the beginning, primitive man realized that to survive withother human beings should be organized. In 'Totem and Taboo', was already seen how the family spent the early fraternal alliance, where the mutual restrictions (taboo) allowed the establishment of the new social order, more powerful than the isolated individual. This restriction led to deflect the sexual impulse toward another end (an end-inhibited pulse) generated a kind of love for all humanity, but not fully annulled direct sexual satisfaction. Both variants seek to unite the community with stronger links than those derived from the need to organize to survive.
But soon there is a conflict between love and culture: love is opposed to the interests of culture, and it threatens to restrictions. The family advocates love, and the broader community culture. restricted to culture sexuality canceling its manifestation, and that culture needs energy for its own consumption. In 'Beyond the pleasure principle' had been nominated two instincts: life (Eros) and aggression or death. They are not isolated and can be complemented, for example when the aggression directed outward saves the subject of self harm, or preserve his life. Libido is the energy of Eros, but more than this, is the biggest obstacle aggressive tendency that is opposed to culture. Mutual aggression between humans endanger society itself, and it is not held together solely by survival needs, hence the need to build loving relationships among members.
