The conception of social capital has revitalized the study of civil society. Alexis de Tocqueville's examination of 19th-century America is a major source of inspiration for much of this work. Tocqueville's analysis has been used to help support the idea that a strong civil society is crucial to democratic success. A reconsideration of Tocqueville's analysis, and, more important, of his American case, however, suggests that an active civil society is not an unalloyed good for democratic politics. A strong society can be not only a support but also a threat to democracy and liberal democratic ideals. One's evaluation of the health of democratic politics must depend on a study of the effects of political institutions and constitutional structures, as well as of civil society.
