Civil society refers to a wide variety of communities and groups such as non-governmental organizations (NGOs), labor unions, indigenous groups, charitable organizations, faith-based organizations, professional associations, and foundations that function outside of government to provide support and advocacy for certain people or issues in society.
Sometimes called the “third sector” to differentiate it from the public sector—which includes the government and its branches—and the private sector—which includes businesses and corporations—social society has the power to influence the actions of elected policymakers and businesses.
While the concept of civil society in the context of political thought continues to evolve today, its roots date at least as far back as Ancient Rome. To Roman statesman Cicero (106 BCE to 42 BCE), the term “societas civilis” referred to a political community encompassing more than one city that was governed by the rule of law and typified by a degree of urban sophistication. This kind of community was understood in contrast to uncivilized or barbarian tribal settlements.
During the 17th century Enlightenment era, English writers like Thomas Hobbes and John Locke added social and moral sources of the legitimacy of the state or government in relation to the idea of civil society. In contrast to the widely held thought in ancient Greece that societies could be characterized according to the character of their political constitution and institutions, Hobbes and Locke contended that as an extension of their “social contract,” society was conceived before the establishment of political authority.
Between these two perspectives, 18th-century Scottish economist Adam Smith put forward the concept that civil society emerged from the development of an independent commercial order. Within this order, Smith contended, a chain of interdependence between predominantly self-seeking individuals proliferated, and an independent “public sphere,” where the common interests of society as a whole could be pursued. From Smith’s writings, the idea that the public possessed its own opinions on matters of common concern and that such “public opinion” as shared in visible forums like newspapers, coffeehouses, and political assemblies could influence elected policymakers.
Considered the main representative of 19th-century German Idealism, philosopher G. W. F. Hegel developed an understanding of civil society as a non-political society. As opposed to classical republicanism civil society, which was generally synonymous with political society, Hegel, as had Alexis de Tocqueville in his classic book Democracy in America, Tocqueville saw separate roles for civil and political societies and associations. As had Tocqueville, Hegel argued that the direct role these associations played in solving problems meant that they could be solved without having to involve the federal or state government. Hegel considered civil society to be a separate realm, a “system of needs,” representing the “difference which intervenes between the family and the state.”
By the 1980s, the importance of the social society as originally envisioned by Adam Smith became popular in political and economic discussions as it became identified with non-state movements that were defying authoritarian regimes, especially in central and Eastern Europe and Latin America.
The English and German versions of civil society have been particularly influential in shaping the thinking of Western theorists since the late 20th century. After rarely being discussed during the 1920s to 1960s, civil society had become common in political thought by the 1980s.
Various modern neoliberal theorists and ideologues have strongly adopted the English version as synonymous with the idea of the free market accompanied by a powerful but constitutionally limited government. This idea played a key role in the idealization of civil society that arose in eastern European intellectual circles following the fall of the Berlin Wall in 1989 and the collapse of the Soviet Union in 1991. In these settings, civil society signified either the growth of a web of free autonomous associations that were independent of the state and that bound citizens together in matters of common concern or a necessary means of achieving the economic prosperity and civil liberties of Western democracy.
At the same time, the German interpretation’s concern with the sources and importance of the ethical ends learned through participation in the corporations of civil society reemerged in the work of a body of American political scientists and theorists who came to view civil society organizations as sources of the stocks of human capital and mutual public-private cooperation required by a successful democracy.
During the 1990s, many authors, politicians, and public authorities came to view civil society as a sort of “Swiss Army knife” for fixing the many problems facing developing countries. Relatedly, civil society emerged as a mainstay of academic thinking about democratic transitions and a familiar part of the discourse of global institutions, leading nongovernmental organizations, and Western governments.
During the 1990s, in particular, many authors, politicians, and public authorities keen to find solutions to some of the different kinds of problems facing developing countries seized upon civil society as a kind of panacea. Relatedly, this term became a conceptual mainstay of academic thinking about democratic transitions and a familiar part of the discourse of global institutions, leading nongovernmental organizations, and Western governments. The ideological character and political implications of such ideas have become increasingly clear over time. Such thinking helped sustain various attempts to kick-start civil societies from “above” in different African countries, for example, and simultaneously served to legitimize Western ideas about the kinds of political structure and economic order appropriate for developing states. In philosophical terms, applying civil society in this kind of way raises the profound question of whether it can be removed from its status within the Western political imagination and applied in ways that are appropriate for the indigenous developmental trajectories and political cultures of some of the poorest countries in the world.
By the end of the 1990s civil society was seen less as a cure-all amid the growth of the anti-globalization movement and the transition of many countries to democracy and more as a means of justifying its legitimacy and democratic credentials. As non-governmental organizations and the new social movements emerged on a global scale during the 1990s, civil society as a distinct third sector became treated as more of a means of establishing an alternative social order. Civil society theory has now assumed a rather neutral stance with marked differences between its nature of implementation in richer societies and in developing states.
While “civil society” has become a central theme in the modern discussion of philanthropy and civic activity, it remains hard to define, deeply complex, and resistant to being specifically categorized or interpreted. In general, the term is used to suggest how public life should function within and between societies. It also describes the social action that occurs within the context of voluntary associations.
Civil society is made up largely of organizations that are not associated with the government, such as schools and universities, interest groups, professional associations, churches, cultural institutions, and—sometimes—businesses. Now considered essential to a healthy democracy, these elements of social society are an important source of information for both citizens and the government. They monitor government policies and actions and hold government leaders accountable. They engage in advocacy and offer alternative policies for the government, the private sector, and other institutions. They deliver services, especially to the poor and underserved. They defend individual rights and work to change and uphold accepted social norms and behaviors.
