To begin with, the author introduces features of private life friendship. From that perspective, he observes “friendly” elements of social life. He describes a continuous spectrum of communities – from the ones which are united by the highest number of positive ties to those full of fight and hatred. The author points out that even in a fight to death one feels some remnants of positive ties with an enemy as a human being. He calls this phenomenon “a friendship with an enemy”. Even a little experience of “the friendship with an enemy” gives power to use possibilities of friendly relations with a stranger – the most common type of human we meet in social life. The author points out that high culture, as well as social climate are the conditions of developing positive ties.
