The books tries to answer the question: "What holds society together?" by using theoretical conceptual tools of Parsonisan functionalist sociology. I work exepcially with Parsons's concept of societal community and then I try to reconstruct this concept by using thouhts of others authors (Jeffrey Alexander, Richard Münch, Shmuel Eisenstadt, David Lockwood, Stein Rokkan, Lewis Coser and John Rawls).
