Communitarianism is a philosophy that emphasizes the connection between the individual and the community. Its overriding philosophy is based upon the belief that a person's social identity and personality are largely molded by community relationships, with a smaller degree of development being placed on individualism. Although the community might be a family unit, communitarianism usually is understood, in the wider, philosophical sense, as a collection of interactions, among a community of people in a given place (geographical location), or among a community who share an interest or who share a history.
The philosophy of communitarianism originated in the 20th century, but the term "communitarian" was coined in 1841, by John Goodwyn Barmby, a leader of the British Chartist movement, who used it in referring to utopian socialists, and other idealists, who experimented with communal styles of life. However, it was not until the 1980s that the term "communitarianism" gained currency through association with the work of a small group of political philosophers. Their application of the label "communitarian" was controversial, even among communitarians, because, in the West, the term "communitarian" evokes associations with the ideologies of socialism and collectivism; so, public leaders—and some of the academics who champion this school of thought—usually avoid the term "communitarian", while still advocating and advancing the ideas of communitarianism.
The term is primarily used in two senses:
While the term communitarian was coined only in the mid-nineteenth century, ideas that are communitarian in nature appear much earlier. They are found in some classical socialist doctrine (e.g. writings about the early commune and about workers' solidarity), and further back in the New Testament. Communitarianism has been traced back to early monasticism, but in the twentieth century began to be formulated as a philosophy by Dorothy Day and the Catholic Worker movement. In an early article the Catholic Worker clarified the dogma of the Mystical Body of Christ as the basis for the movement's communitarianism. Communitarianism is also related to the personalist philosophy of Emmanuel Mounier.
